HPDC vs LPDC Die Casting High-pressure die casting(HPDC) High-pressure casting is a process in which molten metal is poured into a pressure chamber so that the molten metal fills the mold cavity at high speed and then solidifies under high pressure to form a casting. The flow speed during filling can reach 30-80mm/s, and the time for filling the cavity is extremely short. ​ Advantages and disadvantage of HPDC It has the advantages of good surface finish, stable dimensions, and direct molding of thin-walled structures. It is mainly used for the manufacture of shells and other castings, Its work efficiency is high, and it will also provide a smoother surface for finishing. The surface finish depends on the finish of the mold. This high-quality surface can be directly applied to other paints. However, the disadvantage is that it generates high operating and investment costs. In high-pressure production, thicker parts may be difficult to cast. Porosity may also occur in high-pressure die-casting parts, which generally cannot be heat-treated and have high operating costs. ​ Feature and application of HPDC High-speed, high-pressure, and metal casting are the main characteristics of pressure casting production. Thin-walled castings with complex shapes can be cast, and fine grains, holes, teeth, grooves, etc. can be directly cast. The dimensional accuracy and surface quality of the castings are relatively high. High, realizing less cutting or no cutting. Due to the high production efficiency of this die-casting machine and the high metal utilization rate, the application in the die-casting production of zinc, aluminum, and magnesium alloys has a growing trend. The strength and surface bending hardness of the casting are higher, and the tensile strength is 25%~30% higher than that of sand casting. However, due to the fast filling speed of liquid metal, the gas in the cavity is difficult to discharge, and it is often filled with gas under the surface Therefore, under normal circumstances, die castings cannot be heat treated or mechanically processed to avoid porosity on the surface of the casting. HPDC mainly used for the mass production of non-ferrous metals such as aluminum, magnesium, zinc, copper, etc., and it is widely used in industries such as automobiles, meters, electronics, aerospace, lighting, furniture, mechanical, hardware, and communication, etc. In recent years, new technologies such as vacuum die casting, new processes, as well as new equipment such as double-punch die-casting machines, horizontal parting full-vertical die casting machines, etc., have continued to emerge. Although the quality of castings has been greatly improved to effectively control casting defects, there are still have pores, shrinkage holes, and shrinkage porosity. At the same time, due to the continuous emergence of new die-casting materials, the scope of application of die casting will continue to expand. Free Quote & Part Analysis → Low-pressure die casting(LPDC) LPDC is to make the liquid alloy fill the cavity from bottom to top under lower pressure, and crystallize under pressure to cast the casting part. Therefore, compared with high-pressure casting, the pressure is different and the direction of liquid metal flow is different, and it can be heat treated. ​ Advantages and disadvantage of LPDC Due to the stable filling of LPDC and the same direction of liquid flow and airflow, the castings produced by casting have fewer defects such as porosity and slag inclusion; the structure is dense and the mechanical properties of the castings are high; the filling ability is strong, which is conducive to the formation of clear and clear contours. Castings with smooth surface, so important aluminum alloy castings will be low-pressure casting. Although LPDC has a dense structure and better mechanical properties, its productivity is low. After HPDC, the surface quality is better, but there are inevitably some pores inside, and its productivity is high, so it is more suitable for thin-walled castings, but the castings are shrinkage and loose, not dense, and are not used for castings with high airtightness requirements. Feature and application of LPDC LPDC is used when selecting castings with high air-tightness requirements. The production batch is large, and small and medium-sized non-ferrous metal castings without tightness requirements are HPDC. The difference is that LPDC parts can be strengthened by heat treatment, and the toughness can be greatly improved. Therefore, the design depends on the product wall thickness and the weight of the entire product. If the wall thickness is thicker and the product weight is heavier, the LPDC process should be selected. Otherwise, if the wall thickness is lighter, the HPDC process should be selected. The feature of LPDC as below: LPDC can use sand, metal, graphite, etc., and has the following advantages: Filling with pure molten metal improves the purity of castings. The molten metal fills smoothly, thereby reducing the formation of oxide slag. The casting has good moldability. The molten metal is filled under pressure, which can improve the fluidity of the molten metal, which is beneficial to the formation of castings with clear contours and smooth surfaces, and is more beneficial for the molding of large thin-walled castings. The casting is solidified under pressure, and the structure of the casting is dense. Convenient production and operation, good working conditions, high production efficiency, and easy realization of mechanization and automation. contact

How to extend the life of die casting dies The service life of die-casting dies is closely related to the material, design, manufacture, and maintenance. In the actual application, we found, affect the die-casting dies life of the proportion of each element is rough as follows: mold design and manufacturing about 80%; including mold materials about 10% ~ 15%; mold use and maintenance and maintenance of about 5% ~ 10%. Take the following measures is to avoid die-casting mold failure, improve its life effective method. 1. Mold material 2. Mold design 3. Mold manufacturing 4. Heat treatment of the mold 5. Use and maintenance of the mold 1. Mold material 1 Die cavity material should be selected with the excellent overall performance of the hot work mold steel. Try to use finer grain, isotropic good, good heat treatment performance of the material as the mold cavity material. At present, the domestic common use SK61, DACS5, 8407, and other imported materials as mold cavity materials. Before the mold material is put into processing, the appearance inspection, metallographic inspection, and ultrasonic flaw inspection should be used to check the material to avoid using defective material, which will cause early scrap of the mold. 2. Mold design 2 (1) Pouring system design The pouring system design is the core part of die casting mold design, especially the position and size of the inner sprue. When choosing the location of the inner sprue, try to avoid the frontal impact of the aluminum liquid on the core, in order to reduce the generation of erosion. In the case of ensuring that the casting is well-formed, increase the cross-sectional area of the inner sprue, so that the aluminum liquid enters the cavity in the form of laminar flow, thus reducing the speed of the inner sprue and reducing the impact of the aluminum liquid on the cavity. (2)Forming parts design As far as possible to avoid sharp corners, in order to prevent the corresponding parts of the mold due to stress concentration and cracking. The unavoidable vulnerable parts, such as the slender core, should be used in a reasonable patchwork structure, so as to facilitate timely replacement when damaged. (3)Formwork design Determine the appropriate thickness of the template, so that it has sufficient rigidity and strength to effectively resist bending deformation. In the template, especially the structure design of the moving mold template, the integral template instead of the traditional support plate and through the template, is conducive to improving the overall bearing capacity of the die casting mold. (4)Design of guiding parts First of all, each guide part should choose the correct tolerance fit and surface roughness level. Second, improve the structure of the guiding parts, such as with the slider with the side and bottom surface into easy to replace the guide slip, while the guide slip chooses to wear resistance and thermal expansion of better alloy materials. (5) Easy to replace the design of maintenance For the easily damaged core and sliding fit parts, design the structure to facilitate rapid replacement and maintenance. Such as the core from the step-type fixed structure to the screw-type connection structure. (6) Maintain the thermal balance of the mold Reasonable design of cooling system to ensure the overall thermal balance of the mold. If conditions permit, you can choose to configure the mold temperature balancing system. (7)Apply CAD/ CAE technology CAE simulation analysis is carried out to determine the distribution of temperature field, flow field, and stress field of the mold after the preliminary design has been completed. And on this basis, the mold design optimization, in order to improve the overall quality of mold design, so as to improve the die casting mold life to provide a strong guarantee. 3. Mold manufacturing 3 (1)Develop reasonable processing technology The machining process of the mold is the link that directly affects the life of the mold and needs to pay attention to the details of the process. For example: choose the appropriate processing benchmark, it is best to unify the parts of the processing benchmark, in order to reduce the cumulative error; two-sided butt method of processing longer cooling water hole, in order to ensure the smooth surface of the water hole at the same time, should also pay attention to ensure its coaxial, to avoid stress concentration and cracking; comprehensive use of CAD / CAM technology, improve the accuracy of processing, etc. (2)Electric discharge machining EDM is widely used in mold manufacturing. After EDM, a hardened layer appears on the surface of the cavity. The thickness of the hardened layer is determined by the current intensity and frequency of machining, which is deeper for rough machining and shallower for finishing.2 No matter how deep or shallow the hardened layer is, it will produce large stress on the surface of the mold. Therefore, the hardened layer should be eliminated or stress relieved by high-frequency EDM and other technological measures. (3) Grinding The large amount of frictional heat generated by grinding may soften the surface of the mold and reduce its ability to resist thermal fatigue, thus causing early failure of the mold. Therefore, when grinding, the amount of coolant should be moderate, and avoid excessive grinding volume and feed to avoid fine cracks in grinding. (4)Weld repair Welding is a common means of repairing mold processing errors. When welding, the surface is thoroughly cleaned and dried, the mold is preheated to 440~460℃ together with the welding rod, and after the surface of the mold is at the same temperature as the heart, the welding is carried out under protective gas. After the repair is completed, temper once at a temperature 50~80 below the original tempering temperature to eliminate stress. (5)Polishing Focus on polishing the narrow seams and deep grooves in the cavity to ensure that the overall roughness of the cavity reaches 0.2um, so as to reduce the flow resistance of the cavity surface and improve its resistance to galling and fatigue. 4. Heat treatment of the mold 4 (1)Quenching and tempering Vacuum quenching can effectively prevent the cavity surface decarburization and carbonization, reduce the early cracking of the mold caused by inadequate dissolution of carbide during heat treatment. After vacuum quenching, 2~4 times tempering is required. In general, the larger the mold, the higher the quenching temperature, and the lower the tempering temperature. (2)Stress relief tempering The new mold in the mold after passing the test should be tempered to eliminate stress. (3)Nitriding Nitriding treatment of cavity surface can improve the ability of mold surface to resist wear, adhesion, and thermal fatigue. After the new mold is qualified, the first nitriding is carried out. In the process of use, the timing of nitriding is determined according to the specific maintenance procedures and the condition of the mold. When nitriding, the hardness of the nitriding substrate should be between 35~43HRC, and the thickness of the nitriding layer should not exceed 0.15mm, and attention should be paid to the cleanliness of the nitriding surface to ensure the uniformity of the nitriding layer. When the cracking of the mold is serious, nitriding is not suitable. 5. Use and maintenance of the mold 5 (1)Reasonable setting of die-casting process parameters Under the premise of ensuring the quality of the castings, try to reduce the pouring temperature of the aluminum liquid, injection speed and injection pressure, shorten the high temperature holding time, especially to eliminate the practice of relying solely on increasing the injection pressure to improve the quality of the castings. In addition, you can use the parameter tester to seek the best combination between the parameters. (2) Evenly preheat the mold Avoid using the gas heating method to preheat the mold to prevent different thermal expansion of each part due to uneven preheating. It is better to preheat the mold with the oil temperature of the mold temperature machine. In the case of no mold temperature machine, can use the method of several molds before test pressing, rely on aluminum liquid preheat mold cavity. (3)Spraying evenly Focus on spraying the deep cavity of the mold, and at the same time, pay attention to avoid long-time spraying. (4)Keep the heat balance of the mold Regularly check and clean the cooling system to prevent the cooling water channel from being blocked, so as to ensure a stable mold temperature. (5)Timely mold inspection Pay attention to check whether there are cracks, crazing, and erosion on the mold surface. If these conditions appear, it is necessary to use the method of welding repair in time. If the nitriding layer on the surface of the mold cavity is partially damaged, the nitriding treatment should be carried out again. (6) Periodic stress relief tempering This is an effective method to retard cracking. According to the size and complexity of the mold to determine the time interval of stress-relieving tempering. In general, the aluminum alloy die casting mold in the first batch production 5000 ~ 8000 times, after every 10000 ~ 15000 times for stress relief treatment. However, if the mold cracking is serious, it is not suitable to carry out stress relief tempering, so as not to intensify the expansion of cracks. (7)The mold maintenance when stopping During the production, when stopping temporarily, you can reduce the cooling water flow and let the mold cool slowly. If it is stopped for a long time, the mold must be thoroughly cleaned and maintained and put into storage after passing the inspection. (8) Operation training Pay full attention to the operator's work training, to eliminate the mold damage caused by improper operation. Conclusion: Improving the life of aluminum alloy die-casting mold is a comprehensive technical issue. In the actual application, comprehensive consideration of the role of the influencing factors, and take targeted measures, it is possible to improve the service life of aluminum alloy die-casting dies. contact

​ FLOW PATH How long does it take to turn ideas into reality and drawings into real products? Generally, different industries have different production cycles. For the die casting mold industry, the processing volume is determined according to the size and structure complexity of the parts. CAMEL DIE got a set of a die-casting mold project from one of our American customers in May of 2020. This die-casting part is a metal gasket used on aircraft seats. Due to the product design updates and change in the number of cavities from 2 cavities to 4 cavities we provided the updated quotation within 24 hours with all related details such as the mold base, tool action (slider requirement), cavities, estimated casting machine size for the first trial, estimated die casting mold size(mm), estimated mold life, design confirmation timing, steel cutting to T1 (weeks), mold cost and freight cost. etc. CAMEL is committed to improving our response speed. Serving our customers and fulfilling their requirements is our standard. When our client wanted to proceed to start this project however, they needed to expedite the lead time to 5 weeks instead of the 8 weeks we had originally quoted. Had this requirement not been met, we would have stood to lose the order. After strong communication with our team of experts and the detailed evaluation of this project, we determined that it could be completed in advance within the required time. To support long-term cooperation with our customer, we proceeded with the designing in advance before we got the order. This saved us one week of lead time, and we were thus able to adjust the processing schedule accordingly. With our strong motivation to go above and beyond our customer’s expectations to build quality molds we thrive on being flexible with lead time without cutting any corners. After we confirmed the completion of the required changes with our customer the order was promptly confirmed. Upon receiving the order confirmation, we immediately began to prepare for the die casting mold design and submitted the product analysis report in one working day. In the DFM report, all details were confirmed with our client, such as the parting line, injection pin, visible areas, inserts, split lines, ejection location, engraving & cavity, radii, machining & allowance, complete information of the die-casting machine, clamping slot, etc., as well as some suggestions about the parts. ​ The mold flow analysis report was provided within 3 working days and the 3D mold drawing in 2 working days. Our teamwork cooperation and communication were smooth and efficient and because of that the design confirmation was completed in one week. During the mold building process, we strictly followed our project management system in order to ensure quality control. If there were any pending questions that required confirmation with our clients our team ensured that a prompt reply was provided with our suggestive solutions so that everything remained on schedule. Because of our teams’ strong work ethic and attention to detail the entire project went very smoothly and in fact we were able to finish the project one week in advance which our client was incredibly pleased with. During the mold building process, we made sure to keep our client up to date on every step and detail to ensure we were all on the same page. An example of this is that we submitted the tooling schedule and weekly report status with pictures of the mold process. After we finished the mold build and completed the T1 trial, we provided our client with the trial report with detailed photos of the mold and parts. We also provided the die casting machine parameter data. The FAI report was provided in 3 working days to ensure all measurements were in the correct tolerance . After inspection by our engineers, we confirmed that there were no issues with the samples and sent 5-10pcs to our customer for assembly inspection. The whole project went exceptionally smooth. As normal it took 7 days by express freight for our client to receive the samples. After inspection and measurement confirmation our client provided feedback to CAMEL If there were any updated suggestions. With detailed review and confirmation our client approved these samples after 2 weeks then informed us to arrange the mold shipment. We promptly proceeded with inspecting all mold components, assembling the mold, and running one more trial before shipment. CAMEL has more than 12 years of experience in the mold industry, and in order to support our customers well, we have also developed multiple after-sale partnerships in the customer's area, which can provide mold landing services and follow-up parts replacement services, as well as technical support if needed.

How does cold-chamber die casting machine work During operation, the pressure chamber is placed vertically, and the upper punch is above the pressure chamber, and the lower punch is located at the position where the nozzle orifice is blocked, to prevent molten metal from pouring into the pressure chamber and flowing into the nozzle hole by itself. The opening and closing movements of the mold move horizontally. After the mold is opened, the die casting remains in the movable mold. The working steps of the cold chamber die casting machine are as follows: Close the mold. Pour molten metal into the press chamber manually or by other means. The upper punch moves down at a lower injection speed and enters the pressure chamber until it just touches the molten metal surface. When the upper punch is turned to a higher injection speed and pressed down, the lower punch and the upper punch will move down synchronously while maintaining the relative distance between the upper punch and the molten metal. When the lower punch moves down to let out the nozzle orifice, it just descends to the nozzle part and is supported, therefore, the upper and lower punches squeeze the molten metal at high speed to the nozzle hole (part of the sprue) injection. The molten metal is filled into the mold cavity from the inner gate through the sprue composed of the nozzle, the sprue sleeve, the tapered hole of the fixed mold, and the diverter. After the filling is completed, the upper punch can still maintain a certain pressure until the molten metal in the cavity is completely solidified into the die casting 1, and the molten metal in the runner and the pressure chamber solidifies into the direct gate and the remaining material respectively cake. The upper punch lifts and resets; at the same time, the lower punch moves upwards to cut away the remaining cake that is still connected to the straight gate. The lower punch continues to rise, lift the remaining cake out of the top surface of the pressure chamber, and then take it away manually or by other means. Move the lower punch down and reset to block the nozzle orifice. Open the mold, the die-casting part and the straight gate remain on the movable mold together, and then eject and take out the die-casting part; once the remaining material cake is cut away, the mold opening action can be executed immediately, or it can be executed at an appropriate time, Has nothing to do with the movement of the lower punch to complete the lifting and resetting.

Installation and debugging of die casting mold 4.7.1 Mold installation 1.Preparation before installation (1) Familiar with process documents 1) According to the product drawing and mold assembly drawing, understand the mold structure and working characteristics, understand the mold ejection method, core pulling method and fixing method. 2) Understand the relevant process documents and the main technical parameters of related die-casting. (2) Check the mold and installation conditions 1) Understand the structural characteristics of the mold to be installed. 2) Check the mold: ① Check the sign to understand the basic information. Check the overall dimensions of the mold, whether the length and width can be installed on the selected die-casting machine, whether it is within the distance of the tie rod, if there is a hydraulic cylinder, check whether it can be directly installed, if not, you need to determine whether it can be connected to the mold after installation On the mold; ②Check the total height of the mold, the total height should be greater than the minimum opening of the machine, and the total height of the mold + the mold opening stroke should be less than the maximum opening of the machine; ③Check the mold opening stroke, whether there is enough distance after the mold is opened Eject and remove the casting. Minimum stroke: the maximum height of the protruding part of the movable mold + the maximum height of the casting + the reserved margin 3~5m; ④Check whether the size and position of the mold fixing holes, lifting holes and slots are appropriate; ⑤Check whether the installation position of the mold cooling water pipe interferes; ⑥Check whether the top (pull) rod position corresponds to the machine, and whether the pull position has tooth patterns; ⑦Check whether the sprue sleeve and the machine nozzle size and matching method are appropriate; horizontal machine The inner diameter and height of the sprue sleeve are the same as the basic size of the nozzle; the vertical and hot chamber machinesThe mold inlet hole is generally 0.5~1.0mm larger than the machine nozzle; ⑧ check whether the movable parts of the mold are flexible; ⑨If necessary, open the mold to check the mold cavity, clean the mold installation joint surface must be wiped clean, there must be no oil and debris; the edge of the spray liquid should be removed, ready for installation. (3) Turn on and check the die casting machine 1) Whether the work is normal, each mechanism is in good condition, the movement is stable, and the ejector rod is reset. 2) Adjust the movable and fixed template to the proper position, clean the installation surface, and remove oil and debris. (4) Check the lifting equipmentCheck whether the hoisting equipment is normal, safe and reliable.Prepare the relevant tools for installing the mold, such as wrenches, pressure plates, bolts, hooks (rings), afterburners, cooling water pipes (5) Preparation toolsPrepare the relevant tools for installing the mold, such as wrenches, pressure plates, bolts, hooks (rings), afterburners, cooling water pipe joints, tie rods, etc. 2. Install the mold According to the size and weight of the mold, it can be divided into small molds, medium molds, (super) large molds, and mold installation steps are roughly the same, but there are some differences. Small molds can generally be moved and installed directly, which is very easy. Medium and large molds must be installed by special hoisting equipment. The difference is that large molds generally use splitHoisting, that is, moving and fixed molds are installed separately. The following are the basic steps of mold installation: (1) For hoisting, use a crane or other special lifting tools to hoist the mold between the movable and fixed template of the machine tool. First, the plane of the fixed mold and the fixed template of the machine tool should be close. (2) Properly adjust the position of the hoisting equipment so that the press chamber or nozzle of the machine tool is inserted into the hole of the mold sprue, and the positioning is done. (3) Start the machine, make the movable mold of the machine tool approach slowly, and stop when the mold is 3~5mm closed. (4) Confirm that the mold is positioned accurately, click to close the mold, close it slowly, check it carefully, and close it slowly. (5) Turn off the machine, install the pressure plate (note that the pressure plate should be flattened), lock the movable and fixed molds on the movable and fixed template of the machine respectively, and tighten the bolts. (6) Fasten the movable and fixed molds with afterburners, and they shall not be loosened. (7) Install auxiliary systems, such as cooling water pipes, hydraulic oil pipes, tie rods, etc. (8) Complete the installation, clean up and put away the tools. 3 matters needing attention (1) The fixed mold should be installed before the large mold is installed, but the fixing device cannot be tightened when the fixed mold does not fall off. You must wait for the fixed mold to be installed and closed before tightening together. (2) When installing the mold, pay attention to safety, and the operator cannot be directly under the lifting mold. (3) When the mold is installed, there are 2 people andWork together to ensure safety, and then act in unison. 4.7.2 Mold debugging After the mold is installed, relevant inspections need to be done before the mold can be opened and debugged. Be careful during the debugging process. The machine action should not be too large at a time, otherwise the mold will be easily damaged when there is an abnormality, especially if there is a core pulling device and a reset mechanism. Mold. (1) Adjust the clamping force according to the process regulations and the machine manual. (2) Select a reasonable machine action program according to the process requirements (3) If you need to pull the core first and then open the mold, check the hydraulic core pulling system, whether the oil circuit is unobstructed, whether the core pulling action is smooth, and whether the core pulling position sensor works normally (for the later core pulling, you can check after opening the mold). (4) Check the overall installation and tightening status of the mold. (5) Open the mold slowly, and stop immediately if there is any abnormality (to avoid mold damage, you can click to open the mold). (6) Adjust the ejection device of the machine tool after the movable template is in place and stop to ensure that the ejection distance is reasonable. (7) If there is no abnormality, open and close the mold slowly several times. During the process, pay attention to observe whether the movement of the machine tool and the mold is stable and there is no abnormality. (8) After determining the reliability, add lubricating oil to the movable part, and then open and close the mold to check to ensure that it is working properly.

Steps Of Die Casting Die(HPDC Mold) Design III Die casting mold design, We often said as design of die casting dies or die casting die design. Also, Which be called die casting mould design in some countries. The basic die casting die design steps are summarized as follows: 1. Understand and determine the task 2. Design preparation 3. Select the parting surface and die casting system 4. Choose the die casting equipment 5. Determine the appropriate mold structure and draw the mold assembly sketch * 6. Calculation and verification of relevant parameters * 7. Draw the die casting mold pattern * 8. Proofreading and review * 9. Organize and archive design materials At last, The steps 7-9 of die casting mold design on this page. STEPS OF DIE CASTING DIE(HPDC MOLD) DESIGN III 7. Draw the die casting mold pattern * 7 Draw according to the national drawing standards, sometimes combined with factory custom drawing methods that are not specified by the national standards 1) Draw a die-casting drawing Before drawing the mold assembly drawing, the die-casting drawing should be drawn, and it should meet the requirements of the part drawing and process data. The size guaranteed by the next process should be marked with the words "process size" on the drawing. If after die-casting, except for repairing the burrs, no other machining is performed, then the process drawing is exactly the same as the part drawing. It is best to mark the part number, name, material, material shrinkage rate, drawing ratio, etc. under the die-casting drawing. Die casting drawing and material shrinkage are usually drawn on the mold assembly drawing. 2) Draw the mold assembly structure diagram The die-casting mold assembly drawing reflects the assembly relationship between the parts, the shape and size of the main parts and the working principle of die-casting. When drawing the mold assembly drawing, try to use a 1:1 ratio, first start drawing from the cavity, and draw the main view and other views at the same time. Code all the part numbers in order, and fill in the detailed list, marking the technical requirements and instructions for use. The mold assembly drawing should include the following: the structure of the pouring system and the overflow system, the position of the parting surface and the method of parting and taking parts, the shape of the mold and the positioning of all connecting parts, the position of the guide, the overall size of the mold, auxiliary tools ( Picking and unloading tools, calibration tools, etc.), related technical instructions, etc. 3) Draw a part drawing In addition to standard parts, all mold parts that need to be self-made should be separately drawn to meet the requirements of mechanical drawing specifications to meet the requirements of delivery processing; the drawing number of the part drawing should be consistent with the part drawing number in the assembly drawing so that it is easy to check the reason The sequence of disassembling and drawing parts of the mold assembly drawing should be: first inside and then outside, first complicated and then simple, first dismantling and drawing forming parts, and then dismantling and drawing structural parts. Graphics requirements: draw according to scale, allowing zoom in or zoom out. The view selection is reasonable, the projection is correct, and the layout is appropriate. In order to make the processing personnel easy to understand and easy to assemble, the graphics should be as consistent as possible with the assembly drawing, and the graphics should be clear. The dimensioning requirements are unified, centralized, orderly, and complete. The order of dimensioning is: first mark the main part dimensions and draft angle, then mark the matching dimensions, and then mark all the dimensions. Mark the mating dimensions first on the non-main parts drawings, and then mark all the dimensions. Other content, such as part name, mold drawing number, material designation, heat treatment, and hardness requirements, surface treatment, graphic ratio, processing accuracy of free size, technical description, etc. must be filled in correctly. 8. Proofreading and review * 8 Check the view positions of all parts drawings and assembly drawings, whether the projection is correct, and whether the drawing method meets the national standards of drawing. Whether the placement of each mold part on the assembly drawing is appropriate and whether it is clearly indicated; whether the part number, name, and production quantity on the part drawing are omitted, whether it is a standard part or a non-standard part; the material, heat treatment, surface treatment, and surface of the mold part Whether the degree of finishing is marked and clearly described; the working size and matching size figures should be correct and no missing size. Check the processing performance (whether the geometric structure of all parts, drawing methods, dimensions, etc. are conducive to processing); whether the position of the parting surface and the precision of finishing meet the needs, and whether there will be flashing. After opening the mold, can it be ensured that the die-casting parts remain on the side of the mold with the ejector device, whether the demolding method is correct, whether the size, position, and quantity of the push rod (push tube) are appropriate, and whether the push plate will be stuck by the core, Will it scratch the die casting parts. Whether the location, size, and quantity of the flow line of the cooling medium are appropriate; whether the location and size of the pouring system and the overflow system are appropriate. When the die casting part has an undercut, whether the mechanism for removing the undercut is appropriate, such as whether the slider and push rod in the inclined pin core pulling mechanism interfere with each other. 9. Organize and archive design materials 9 From the beginning to the success of mold design processing and inspection, the technical data generated during this period, such as the task book, the part drawing, the technical manual, the mold assembly drawing, the mold part drawing, the base drawing, the mold design manual, and the inspection record sheet, Trial and repair records, etc., are sorted, bound, numbered and archived according to regulations.
