The key role pl    ayed by each part of the injection molding machine

    The injection molding machine can take out the cavities of various plastic parts through a simple manipulator, which is conducive to fine molding. The injection molding machine complements each other through various parts, and the various parts are closely connected to each other, so that the performance of the injection molding machine is idealized to meet the needs of users. The professional staff of injection molding machine manufacturers specifically inquired and sorted out the key roles played by each part of the injection molding machine for users who did not understand the injection molding machine, and stopped the following elaboration.

    (1) Injection system: The function of the injection system is one of the main components of the injection molding machine. There are generally three main methods: plunger type, screw type, and screw pre-plasticized plunger injection type. At present, the most common application is the screw type. Its function is that in a cycle of the plastic injection machine, a certain amount of plastic can be heated and plasticized within a regular time, and the molten plastic can be injected into the mold cavity through the screw under a certain pressure and speed.

    (2) Mold clamping system: The function of the mold clamping system is to ensure that the mold is closed, opened and the product is ejected. At the same time, after the mold is closed, sufficient clamping force is supplied to the mold to resist the cavity pressure generated by the molten plastic entering the mold cavity, avoiding the mold opening, and forming the unfavorable status of the product.

    (3) Hydraulic system: The function of the hydraulic transmission system is to provide power for the various actions required by the process of the injection molding machine, and to meet the requirements of pressure, speed, temperature, etc. required by each part of the injection molding machine. It is mainly composed of various hydraulic components and hydraulic auxiliary components, among which the oil pump and the motor are the power source of the injection molding machine. Various valves control the oil pressure and flow rate to meet the requirements of the injection molding process.

    (4) Electrical control system: The electrical control system and the hydraulic system are reasonably coordinated to complete the process request and various program actions of the injection machine. It is mainly composed of electrical appliances, electronic components, meters, heaters, sensors, etc. There are generally four control modes, manual, semi-automatic, fully automatic, and adjustment.

    (5) Heating/cooling system: The heating system is used to heat the barrel and the injection nozzle. The barrel of the injection molding machine manufacturer generally uses an electric heating ring as a heating installation. The device is located outside the barrel and is detected in sections by a thermocouple. The heat conducts heat conduction through the wall of the cylinder to provide a heat source for the plasticization of the material; the cooling system is mainly used to cool the oil temperature, too high oil temperature will cause a variety of problems, so the oil temperature must be controlled.
