Mold, various molds and tools used in industrial production to obtain the required products by injection molding, blow molding, extrusion, die casting or forging, melting, stamping and other methods. This tool is composed of various parts, and it mainly realizes the processing of the shape of the article by changing the physical state of the molding material.
In addition to the mold itself, the mold also needs the mold base, the mold base, and the device for ejecting the parts caused by the mold core. These parts are generally made into universal models. Known as the "mother of industry".
Extended data:
Mould forming materials are divided into hardware mould, plastic mould and its special mould.
Hardware dies are divided into: punching dies (such as punching dies, bending dies, stretching dies, hole-turning dies, shrinking dies, wavy dies, bulging dies, shaping dies, etc.). ), forging die (such as forging die, upsetting die, etc. ), extrusion die, extrusion die, die casting die, forging die, etc.
Among them, with the rapid development of polymer plastics, plastic molds are closely related to people's lives. Generally, plastic molds can be divided into injection molds, extrusion molds and gas-assisted molding molds.
