Basic classification and mold composition of the injection mold
Custom Plastic Extrusion Supplier China shares that injection mould is a tool for producing plastic products. It is also the tool that gives plastic products complete structure and precise size. Injection molding is a process used in the mass production of complex shaped parts. Specifically refers to the heat melts the plastic by the injection molding machine high pressure into the mold cavity, after cooling curing, forming products.
The basic classification of the Plastic Injection
Injection moulds are divided into thermosetting plastic moulds and thermoplastic plastic moulds according to their forming characteristics. According to the molding process, it can be divided into transfer mold, blow mold, casting mold, thermoforming mold, hot pressing mold (pressure molding mold), injection mold, etc., in which hot pressing mold can be divided into overflow type, half overflow type, no overflow type three, injection mold with pouring system can be divided into cold runner mold, hot runner mold two; According to the loading and unloading mode can be divided into two types of mobile, fixed.
The mould of the Plastic Injection
Although the structure of the mold may vary due to the variety and properties of the plastic, the shape and structure of the plastic products and the type of injection machine, the basic structure is the same. The mould is mainly composed of pouring system, temperature-regulating system, forming parts and structural parts. Among them, the casting system and molding parts are the parts in direct contact with plastics, and change with plastics and products. It is the most complex part in the plastic mold, with the biggest change and the highest processing finish and precision required.
The injection mold is composed of moving mold and fixed mold. The moving mold is installed on the moving template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. During injection molding, the moving mold and the fixed mold are closed to form the casting system and cavity, and the moving mold and the fixed mold are separated to take out the plastic products. In order to reduce the heavy mold design and manufacturing workload, the injection mold mostly USES the standard mold frame.
