Introduction to Plastic Mould
- Jun 14, 2017 -

With the rapid development of plastics industry and the constant improvement of general and engineering Plastics in strength, the application scope of plastic products is also expanding, and the dosage of plastic products is also increasing.

Plastic mold is a tool for the production of plastic products. It consists of several sets of parts, the combination of which has a molded cavity. Injection molding, mold clamping on the injection molding machine, molten plastic is injected into the mold cavity, and cooling in the cavity stereotypes, and then the upper and lower mold separation, through the top out of the system will be products from the mold cavity top out of the die, the final mold closed to the next injection molding, the entire injection process is cycle.

General plastic mold by the two parts of dynamic and fixed mode, dynamic mold installed in the injection molding machine moving template, fixed mold installed in the injection molding machine on the template. During injection molding, the casting system and the mold cavity are formed by closing the die and fixed die, and the mould is separated to remove the plastic products.

Although the structure of the mould may be changeable due to the variety and properties of plastic, the shape and structure of plastic products and the type of injection machine, the basic structure is consistent. The mold is mainly composed of pouring system, thermostat system, forming parts and structural parts. wherein the gating system and the molded parts are directly contacting with the plastic, and vary with the plastic and the products, is the most complex in the plastic mold, the change is the biggest, requires the processing smoothness and the highest precision part.
