【正文】 ecision injection molding machine, and some still blank, which is the main gap with industrial countries 。 20036000kN The clamping force。s plastics processing enterprises Xing Luo cloth across the country, the skill levels of the equipment, the equipment of most of the processing enterprises need technological innovation. In recent years, China39。 Injection molding machine The injection molding machine is a kind of plastic machinery, referred to as the injection molding machine or injection molding machine, thermoplastic or thermosetting material the use of plastic mold into various shapes of plastics molding equipment. Injection molding by the injection molding machine and mold. Type The type of injection molding machine: vertical, horizontal, allelectric, but no matter the kind of injection molding machines, the basic functions of two (1) heating plastic to reach the molten state (2) to exert high pressure on the molten plastic. it shot full of mold cavity. Working principle and mode of The working principle of injection molding machine and injection syringe, it is with the thrust of the screw (or plunger), the plasticizing good molten state (ie, viscous flow state), the plastic injected into the mold cavity closed good After curing stereotypes made the process of the products. Injection molding is a cyclical process, with each cycle including: dosing molten plastics to put pressure injection filling Cooling Kaimode pickup. Remove the plastic parts and then reclosed mode, the next cycle. Injection molding machine operating items: injection molding machine operating projects including the control keyboard operation, the operation of electrical control system and hydraulic systems operating in three aspects. Separate action of the injection process, feeding action, injection pressure, injection speed, the top choice of the type, barrel temperature of each monitor, injection pressure and back pressure regulation. Screw injection molding machine molding process: First, granular or powdered plastic in the machine barrel, through which the screw rotates and the outer wall of the barrel, heating the plastic to bee molten state, then the machine before clamping and injection shift, so that the nozzle closely aligns the mold gate Road, then the oil pressure to the injection cylinder Walter, screw forward to high pressure and a faster speed will melt into the closed mold temperature is low , after a certain period of time and pressure to keep (also known as pressure), cooling, curing, the mold can be opened to remove the products (the purpose of holding pressure to prevent the reflux of the melt in the mold cavity, supplementary material to the mold cavity, and to ensure that products have a certain density and 5 dimensional tolerances). The basic requirements of the injection molded plastics, injection and molding. The plasticizing premise to achieve and guarantee the quali
