All kinds of tools and products used in our daily production and life, ranging from the base and body shell of the machine tool to the shell of a germ head screw, button and various household appliances, are closely related to the mold.
The shape of the mold determines the shape of these products, and the processing quality and precision of the mold also determine the quality of these products. Because of the different materials, appearances, specifications and uses of various products, molds are divided into casting molds, forging molds, die-casting molds, stamping molds, and injection molds.
General definition of mould: in industrial production, parts or products made of metal or non-metallic materials by various presses and special tools installed on the presses are generally called moulds.
A set of stamping die is composed of many parts. The quality of the parts directly affects the quality of the stamping die, and the final quality of the parts is guaranteed by finishing, so it is important to control the finishing. In most domestic mold manufacturing enterprises, the methods adopted in the finishing stage are generally grinding, electric machining and bench work processing. At this stage, many technical parameters such as part deformation, internal stress, shape tolerance and dimensional accuracy should be controlled. In specific production practice, it is difficult to operate.
The processing of mold parts can be roughly divided into three categories according to the different appearance and shape of the parts: plates, special-shaped parts and shafts. The common technological processes are roughly as follows: rough machining, heat treatment, fine grinding, electrical processing, fitter (surface treatment), and assembly processing.
