The plastic injection mould is mainly a moulding mould most commonly used in the production of thermoplastic plastic parts. The processing equipment corresponding to the plastic injection mould is a plastic injection moulding machine. The plastic is first heated and melted in the heating cylinder at the bottom of the injection machine, and then injected Driven by the screw or plunger of the machine, it enters the mould cavity through the nozzle of the injection machine and the pouring system of the mould. The plastic is cooled and hardened to form, and the product is released from the mould. Its structure is usually composed of moulded parts, pouring system, guide parts, ejection mechanism, temperature adjustment system, exhaust system, support parts and so on. The manufacturing materials are usually plastic mould steel modules. The commonly used materials are mainly carbon structural steel, carbon tool steel, alloy tool steel, high-speed steel, etc. The injection moulding processing method is usually only suitable for the production of thermoplastic products. The plastic products produced by the injection moulding process are very wide. From daily necessities to various complex machinery, electrical appliances, vehicle parts, etc., are formed by injection moulding. It is the most widely used processing method in the production of plastic products.
