subject: What Is The Mold [print this page] The mold means for plastic pressure, extrusion, injection, blow molding and low foaming molding combined plastic mold, which is mainly composed of concave die combinations of substrates, concave component and die combination clamping plate with variable cavity die, the convex die combinations of substrates, punch, punch combinations of components pallets, cavity truncated component and a side sectional composite plate with variable core of convex mold. The convex die, the concave die and the auxiliary molding system coordination changes. The injection molding machine,filling machine and other mechanical processing of different shapes, different sizes of blow mold series type. Plastics processing industry and plastic molding machine, plastic products to complete the given configuration and precise dimension tool. Because the plastic variety and processing methods are various, plastic molding machine and plastic products structure and character is not a, therefore, plastic mold in the species divided into plastic injection mold, blowing mold types, structures and varied.
As the plastic industry and the rapid development of general and engineering plastics in strength and precision, increases continuously, the application of plastic products is also expanding, plastic products the proportion of is increased rapidly. A reasonable design of the plastic parts can often replace the more traditional metal parts. The amount of plastic products also is on the rise.
The plastic injection mold is a production of plastic products, tools. It consists of several parts components, this combination has a forming die cavity. Using injection molding, the mold clamping in the plastic injection molding machine, the molten plastic is injected into the molding cavity, and the cavity cooling setting, then the upper and lower die separately, through the roof the system will products from the mold cavity top away from the mold, the mold is closed for the next injection, the injection molding process is circular.
Injection mold and blow mold are widely used for manufacture of plastic bottles, but in the plastic bottle production prior to the first is bottle design.
