The injection molding machine is composed of an injection system, a mold closing system, a hydraulic transmission system, an electrical control system, a lubricating system, a heating and cooling system, a safety monitoring system and the like, and is characterized in that the injection molding machine is used for injecting plastic in a plasticized molten state (namely, viscous state) into a closed mold cavity by means of the thrust of a screw (or a plunger), and obtaining a product after solidification and shaping. The selection of injection process action, feeding action, injection pressure, injection speed and ejection type, the monitoring of the temperature of each section of the charging barrel, the regulation of injection pressure and back pressure and the like are respectively carried out.
