[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] During the use of the die-casting mold, since the lower die seat at the bottom needs to withstand a large amount of pressure during use, the lower die seat will be worn out after long-term use, which will cause the position of the upper and lower die seats to be misaligned, resulting in the quality of processing parts by the die-casting mold in the subsequent use, reducing the work efficiency during the part processing process.
