In our daily life and industrial production, often used in a wide variety of industrial supplies, and large plastic mold to the machine's various plastic mold, plastic body shell, small living small items and a variety of household appliances shell, everything is plastic mold and have a close relationship. Determines the shape of the plastic mold shape these products, processing quality and accuracy will determine the quality of these products. This plastic mold products because of different material, appearance, size and purpose, divided into a casting mold, forging mold, die casting mold, stamping mold and other non-plastic mold and plastic mold.
In recent years, with the plastic mold in the industrial life is becoming increasingly popular, rapid technological development and continuous improvement of engineering plastics in common with the strength and accuracy, etc., plastic mold industry and life in the range of applications is constantly expansion, such as: large household appliances, daily necessities, instrumentation, construction equipment, automotive, medical equipment, etc., the proportion of plastic mold is rapidly increased. A well-designed plastic parts can often replace multiple traditional metal pieces. Industrial plastic mold products and household plastic products plastic mold of the trend is rising.
The general definition of the plastic mold: in industrial production, with a variety of presses and special tools mounted on the press, by the pressure of the metallic or non-metallic material of a desired shape of the part or article, this special tool referred to as the mold.
Plastic mold injection molding process must be noted that: plastic mold is a tool for the production of plastic products. It consists of several groups of components parts, the success of this combination mold cavity. When injection molding, plastic mold clamping on the injection molding machine, molten plastic is injected into the mold cavity, and the cavity cooling stereotypes, and then die down separate products through the top of the system will leave from the top of the mold cavity, and finally die again closed for the next injection, the entire injection molding process is a cycle.
