[0002] Engine metal castings are an important mechanical component, commonly used in high-performance mechanical systems such as automobiles, aircraft, and rockets. Metal castings have excellent mechanical properties, wear resistance, and corrosion resistance, and can meet the high strength and high durability requirements of engines. When manufacturing engine metal castings, various materials are usually required, including non-ferrous metals such as aluminum, zinc, and copper, as well as ferrous metals such as iron, chromium, and nickel. These materials are formed into metal castings of various shapes and sizes through processes such as smelting, pouring, and cooling.

[0003] In the process of manufacturing engine metal castings, it is necessary to use stamping equipment to stamp them. During the stamping process, the die is always in contact with the punched sheet, which will cause the working part of the die to be squeezed and produce surface scratches and damage, thereby making the die edge blunt, the gap larger, the shape of the forming part changes, and the surface roughness value increases, which in turn affects the quality and precision of the stamped parts. Therefore, it is necessary to replace the die of the stamping equipment to increase the service life of the stamping equipment, but the replacement of the die on the market is often too cumbersome and cumbersome.
