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

[0003] The existing die-casting mold consists of an upper mold structure and a lower mold structure, and the workpiece is cast through the internal molding cavity of the mold body. However, it has the following defects: (1) When the existing die-casting mold is used to discharge the workpiece, the upper and lower molds are opened, and then the workpiece is lifted up by the ejection structure. Workers stand on both sides of the die-casting workpiece, use tools to clamp the surface of the workpiece, lift the workpiece and move it out of the mold. The discharge process requires the assistance of multiple people, which makes the discharge of the die-casting mold cumbersome and laborious. For this reason, we propose a die-casting mold that is easy to discharge. Utility Model Content
