The structure of plastic machinery injection molding machine is usually composed of injection system, mold closing system, hydraulic transmission system, electrical control system, lubrication system, heating and cooling system, safety monitoring system, etc.<\/p>\n\n\n\n<p>Injection system Function of injection system<\/p>\n\n\n\n<p>The injection system is one of the most important components of the injection molding machine, which generally has three main forms: plunger type, screw type and screw pre plastic plunger injection type. At present, screw type is most widely used. Its function is that in a cycle of the injection molding machine, a certain amount of plastic can be heated and plasticized within a specified time, and then the molten plastic can be injected into the mold cavity through the screw under a certain pressure and speed. After the injection is completed, the molten material injected into the mold cavity is kept shaped. Composition of the injection system: The injection system consists of a plasticizing device and a power transmission device. The plasticizing device of screw injection molding machine is mainly composed of a feeding device, a barrel, a screw, a rubber passing component and a nozzle. The power transmission device comprises an injection oil cylinder, a movable oil cylinder of the injection base and a screw driving device (a glue melting motor).<\/p>\n\n\n\n<p>Mold closing system Function of mold closing system<\/p>\n\n\n\n<p>The function of the clamping system is to ensure that the mold is closed, opened and ejected. At the same time, after the mold is closed, sufficient clamping force shall be supplied to the mold to resist the pressure of the mold cavity caused by the molten plastic entering the mold cavity, and prevent the mold from opening and causing the bad status of the products. Composition of mold closing system: The mold closing system is mainly composed of mold closing device, machine hinge, mold adjusting mechanism, ejection mechanism, front and rear fixed templates, mobile templates, mold closing cylinder and safety protection mechanism.<\/p>\n\n\n\n<p>Hydraulic system Hydraulic transmission system<\/p>\n\n\n\n<p>The function is to provide power for the injection molding machine according to various actions required by the process, and meet the requirements of pressure, speed, temperature, etc. required by various parts of the injection molding machine. It is mainly composed of various hydraulic components and hydraulic auxiliary components, of which the oil pump and motor are the power source of the injection molding machine. Various valves control the oil pressure and flow to meet the requirements of the injection molding process.<\/p>\n\n\n\n<p>electric control system<\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>Injection molding machine is one of the plastic machines commonly used in plastic processing.
