Die casting can be divided into two categories: hot chamber die casting machine pressure casting and cold chamber die casting machine pressure casting, of which cold chamber die casting machine pressure casting is divided into vertical, horizontal and full vertical die casting machine die casting.
Commonly Used Die Casting Machine Die Casting Process
1, Hot press chamber die casting machine die casting process
The pressure chamber of hot die casting machine is in the insulated crucible molten alloy, the press injection parts are mounted on top of the crucible, and when the press injection punch rises, the molten alloy enters the chamber through the inlet. When the die is closed and the press punch is pressed down, the molten alloy fills the die through the nozzle along the channel and cools and solidifies. When the die punch returns, the die is opened and the part is taken, completing a die casting cycle.
2, Die casting process of vertical cold chamber die casting machine
The center of the vertical cold chamber die casting machine is parallel to the parting surface of the mold, which is called vertical side chamber. After closing the mold, the molten alloy poured into the chamber is held by the counter punch which has sealed the nozzle hole; when the press injection punch goes down to the molten alloy, the counter punch starts to descend to open the nozzle and the molten alloy is pressed into the mold cavity; after solidification, the press injection punch returns and the counter punch rises to cut off and push out the residual material; after the residual material is taken away, the counter punch descends to the original position and the mold is opened to take the parts, completing a die casting cycle, this die casting machine is especially suitable for This kind of die casting machine is especially suitable for the production of die casting machine with center gate.
3, Horizontal cold chamber die casting machine die casting process
The center line of the horizontal cold chamber die casting machine is perpendicular to the mold parting surface, called horizontal chamber. After the mold is closed, the molten alloy is poured into the chamber, and the injection punch is pushed forward to fill the cavity through the sprue; when the mold is opened, the injection punch pushes out the remaining material, the die pushing out mechanism pushes out the die casting, and the punch is reset to complete a die casting cycle.
4, The die casting process of all vertical cold chamber die casting machine
The die casting machine with vertical arrangement of die closing mechanism and press injection mechanism is called all-vertical die casting machine, which can be divided into the following two types.
1) The die-casting process of the punch head press type all-vertical cold chamber die-casting machine. The molten alloy is first poured into the chamber and then the die is closed, the pressurized injection punch rises to press the molten alloy into the mold cavity, and after cooling and solidifying, the die is opened and the die casting is pushed out, and the punch is reset to complete a die casting cycle.
2) The die casting process of punch down type all vertical cold chamber die casting machine. After the mold is closed, the molten alloy is poured into the mold, and when the pressurized punch goes down to the molten alloy, the counterpunch goes down to open the channel, and the molten alloy is pressed into the mold cavity through the sprue; after solidification, the pressurized punch returns, and the counterpunch goes up to cut off and push out the remaining material. After the remaining material is taken away, the counter punch is reset to complete a die-casting cycle.
In the above die-casting method, horizontal cold chamber die-casting machine is most widely used.
