注塑机工作原理（Working principle of injection molding machine） The classification of plastic injection molding machine, the working principle and operation of 2009-02-21 at 09:31 plastic injection molding machine is a kind of special plastic molding machinery, it uses thermoplastic plastics, after heated and melted, high pressure to make rapid flow into the mold cavity, after a period of pressure and cooling, a plastic products of various shapes the. Injection function of a complex shape, size precision or with plastic metal insert is dense, is widely used in national defense, electronics, automotive, transportation, building materials, packaging, agriculture, education, health and daily life in various fields. The injection molding process has good adaptability to various plastics processing, high production capacity, and easy to realize automation. Today, with the rapid development of the plastics industry, injection molding machines occupy an important position both in quantity and in variety, thus becoming one of the fastest growing and most productive machines in the current plastics machinery industry. 1, plastic injection molding machine according to the classification of plastic injection molding machine is divided into plastic plunger type plastic injection molding machine and screw type plastic injection molding machine, press machine and drive mode can be divided into hydraulic, mechanical and hydraulic - mechanical (rod) type, according to the operation mode is divided into automatic, semi-automatic and manual plastic injection machine. (1) horizontal plastic injection molding machine: This is the most common type. The die closing part and the injection part are in the same horizontal center, and the mold is opened in a horizontal direction. The utility model is characterized in that the utility model has the advantages of short body, easy operation and maintenance, low machine center of gravity and stable installation; after the product is pushed out, the util
