The definition and development of the injection mould

Posted by: Mu Ju 2021-11-24 Comments Off on The definition and development of the injection mould

General definition of mould: in industrial production, metal or nonmetallic materials are made into parts or products of the desired shape by pressure with various presses and special tools mounted on the presses. The special tools are collectively called molds.

The injection process explains that the mold is a tool for producing plastic products. It consists of several parts, and the combination has a molding cavity. When injection molding, the mold is clamped on the injection molding machine, and the molten plastic is injected into the mold cavity. The mold is cooled and shaped in the cavity, then the upper and lower mold is separated, and the product is ejected from the cavity through the ejection system. Finally, the mold is closed for the next injection molding, and the whole injection process is carried out in a circular way.

The tools and products we use in our daily production and life range from the machine base, the fuselage shell, the small head screw, the button, and the housing of all kinds of household appliances. The shape of the mould determines the shape of these products, and the quality and precision of the mold determine the quality of these products. Mold is divided into casting die, forging die, die-casting die, stamping die and other non-plastic mold, as well as plastic mold.

In recent years, with the rapid development of plastic industry and the continuous improvement of strength and precision of general and engineering plastics, the application of plastic products is also expanding, such as: household appliances, instruments, construction equipment, automobile industry, etc. In many fields, such as daily hardware, the proportion of plastic products is increasing rapidly. A reasonably designed plastic part can often replace many traditional metal parts. The trend of plastic conversion of industrial products and daily products is on the rise.
