Plastic injection mold is a tool for producing plastic products; it is also a tool for the complete structure and precision of plastic products. Injection molding is one of the processing methods used in the production of certain complex parts. Concrete means that the material will be melted by the high pressure into the mold cavity, after cooling and curing, the forming product.
Injection mold according to the characteristics of forming distinguish for thermosetting plastic mold, thermal plastic plastic mold two; according to the forming process of distinction for transfer modeling, blow molding, casting molding, thermoforming mould, hot die (mould, injection mold, the hot pressing die with spilled material and can be divided into overflow type and semipositive, does not overflow type, injection mold gating system can be divided into two kinds of cold runner mold, hot runner mold; according to the loading and unloading mode can be divided into two kinds of mobile, fixed.
Although the structure of the mold because of the plastic varieties and properties, the shape and structure of plastic products and the type of injection machine and so on may vary, but the basic structure is the same. Mainly by die casting system, temperature control system, forming parts and structural parts. The gating system and molding parts is direct contact with the plastic parts, and changed with the plastics and products, mold, the most complex, change is the biggest, the highest part of the smoothness and accuracy of processing.
The injection mold is made up of two parts, the model of the injection mold and the fixed mold, and the dynamic mold is fixed on the mobile template of the injection molding machine. In injection molding movable die and decides the mold closed form pouring system and cavity, mold moves the mold and fixed mold separation to remove the plastic products. In order to reduce the heavy workload of injection mold design and manufacturing, mostly used the standard mold.
