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 resistance. Mold raw materials are one of the life spans of the mold. Due to mold material problems, the quality of the mold is reduced. 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. Again, the unrefined mold steel has a large number of smelting defects, and the forging process of the convex and concave die forging blanks is imperfect, leaving hidden dangers in heat treatment. Imperfect molding technology is mainly manifested in the poor inherent quality of the convex and concave die forging blanks, and problems with the heat treatment technology and process, resulting in the quenching of the convex and concave dies that are not quenchable, have soft spots and uneven hardness. Sometimes micro-cracks or even cracking occur due to insufficient grinding and polishing, and the surface roughness value is too large. Then there is the problem of mold design. Mold design is the fundamental design of the mold, which leads to defective products in the overall product and structural design problems in corporate production efficiency. The die structure is unreasonable and the slender punch has no design reinforcement device. The discharge port is not smooth, causing accumulation and excessive discharge force. The punch is subjected to increased alternating loads, etc.
