CLASSIFICATION OF INJECTION MOULD

Injection molds are divided into thermosetting plastic molds and thermoplastic molds according to their molding characteristics, and according to the molding process, they are divided into transfer moulds, blow moulds, casting moulds, thermoforming moulds, hot-pressing moulds (pressure-moulding moulds, injection molds, etc.),The hot pressing die can be divided into three types: overflow type, half overflow type and no overflow type. The injection mould can be divided into cold runner mould and hot runner mold by pouring system, and can be divided into mobile type and fixed type by loading and unloading mode.

The injection mould is composed of two parts: the moving mould and the fixed mould. The moving mould is mounted on the moving template of the injection molding machine and the fixed mould is mounted on the fixed template of the injection molding machine.During injection molding, the dynamic mold and the fixed die are closed to form the gating system and cavity, and the dynamic mold and the fixed mold are separated in order to remove the plastic products.

Although the structure of the mould may vary greatly due to the variety and properties of plastics, the shape and structure of plastic products and the type of injection machine, the basic structure is the same.Mold is mainly made up of gating system, temperature regulating system, forming parts and structural parts.The casting system and moulding parts are the parts directly in contact with plastics, which vary with plastics and products. They are the most complex, most changeable parts in plastic moulds and require the highest finish and precision.

The gating system refers to the flow section of the channel from the nozzle to the cavity, including the main channel, the cold hole, the shunt channel and the gate, etc.Molded parts are all kinds of parts which make up the shape of products, including dynamic die, fixed mould and cavity, core, molding rod and exhaust port.The typical moulding structure is shown here.
