Description

technical field [0001] The invention relates to the technical field of mold equipment, in particular to a cold pressing mold. Background technique [0002] Mold is a special process equipment, which is the foundation of modern industrial development. The development of many industries cannot be separated from the support of the mold industry. There are many types of molds, such as cold dies, plastic molds, forging molds, powder metallurgy molds and so on. The cold extrusion die is one of the cold stamping dies, and it is one of the advanced less or no cutting processes. It is a processing method in which a solid metal is plastically deformed through a mold cavity to obtain a certain shape of a part under huge pressure and a certain speed at room temperature. However, in the cold extrusion process, because the mold has to bear a large impact force, it often cracks. [0003] Therefore, it is necessary to provide an improved cold pressing die.
