An injection molding machine is also known as an injection molding machine or an injection machine. The main molding equipment is used for manufacturing thermoplastic plastics or thermosetting plastics into plastic products with various shapes by using a plastic molding die. The injection molding machine can heat the plastic, apply high pressure to the molten plastic, and inject it to fill the mold cavity. The injection moulding machine is similar to the injection syringe for injection, and is a technological process in which the plasticized plastic in a molten state (i.e. viscous state) is injected into a closed mould cavity by means of the thrust of a screw (or a plunger), and the product is obtained after solidification and shaping. Injection molding is a cyclic process, each cycle consisting essentially of: quantitative feeding, melting and plasticizing, pressure injection, mold filling and cooling, mold opening and part taking. And taking out the plastic part, closing the mold again, and performing the next cycle.
In the actual production process, due to the difference of the temperature of the injection mold, the molding speed and the cooling demolding speed of the injected liquid plastic are different, so that the molding speed and the cooling speed of the injection molding part are not controlled, the cooling demolding efficiency of the injection molding part is lower, and the specification of the produced plastic part needs to be readjusted by replacing the mold after a batch of products is produced.
