The problem of raw materials for working parts of cover molds is now mixed in China. Many companies cannot buy real products. Improper material selection, poor material performance, and non-wear-resistant mold raw materials are one of the life spans of the mold. Due to mold material problems, the quality of the mold is reduced. decline. Secondly, mold heat treatment is also an important part of mold quality. Unqualified mold raw materials or inadequate heat treatment technology are also the main factors leading to the decline of mold quality. Thirdly, the mold steel is unrefined and has a large number of smelting defects. The convex and concave molds and the forging process are not perfect, and there are still hidden dangers in heat treatment. The mold making process is imperfect, mainly manifested in the poor internal quality of the convex and concave die forging blanks, and problems with the heat treatment technology and process, resulting in the convex and concave dies not being quenched through, with soft spots and uneven hardness. Sometimes micro-cracks or even cracking occur, grinding and polishing are not in place, and the surface roughness value is too large. Furthermore, there is the problem of mold design. Mold design is the foundation of the mold. The design leads to defective products in the overall product and structural design problems in corporate production efficiency. The die structure is unreasonable, the slender punch is not designed with a reinforcement device, and the discharge port is not smooth. Accumulation and excessive unloading force will cause the punch to bear increased alternating loads, etc.
