A pressurized molding machine is an industrial equipment that injected thermoplastic or thermoplastic into the shape cavity through processes such as heating, plasticizing and pressure application, and then cooled and hardened to form plastic products of various shapes. Its operating principle is similar to that of the injection syringe. The propulsion cord (or plunger) transmits the plasticized molten plastic into the closed cavity of the shape, after which the product is hardened and molded. The thermal plast consists mainly of injection system, mold clamping system, hydraulic transmission system, electric control system, lubricant system, heating and cooling system, safety control system, etc. 12
The injection system is one of the most important components of the injection molding machine. It usually has three main forms: plunger type, screw type and casting type with a pre-formed screw plunger. The most widely used type is screw type. Its function is to heat and plasticize a certain amount of plastic over a certain period of time in the injection molten plastic through the screw at a certain pressure and speed. In the shape cavity.
The function of the form clamping system is to close, open and push the product. Moulding is a method of processing used in the mass production of certain parts of complex shape. The specific principle is that the heated and molten plastic material is pushed by a heat plastavtomat cord and injected into the plastic cavity at high pressure. Under the pressure. After cooling and hardening, molded plastic products are obtained.
The hydraulic part includes oil storage tanks, various action cylinders and oil pipelines that transfer kinetic energy through motor pumps, while the electrical part consists of a host computer, a control panel and various electromagnetic valves. Moulding machines can be divided into shape adjustment systems, shape clamping systems, glue injection systems and safety systems according to their mode of operation.
