[0002] Die casting mold is a tool for casting metal parts, a tool that completes the die casting process on a special die casting die forging machine. The basic process of die casting is: the molten metal is first cast and filled into the mold cavity at a low speed or high speed. The mold has a movable cavity surface, which is pressurized and forged with the cooling process of the molten metal, which not only eliminates the shrinkage and porosity defects of the blank, but also makes the internal structure of the blank reach the broken grains in the forged state. The comprehensive mechanical properties of the blank are significantly improved.
