            The all-electric injection molding machine meets the characteristics of reducing energy consumption. It is an injection molding machine that uses a servo motor to replace the original hydraulic device to complete the screw rotation, injection, and mold opening and closing operations. Qingdao injection molding machine's all-electric injection molding machine works basically the same as the traditional hydraulic injection molding machine, except that the control part uses a servo motor to replace the original hydraulic device, and its injection device also includes two parts, plasticizing and driving.

            The plasticized part is composed of a screw, a barrel and a nozzle, and the transmission part is composed of a ball screw, a servo motor, a transmission gear and a clutch. The clamping device of the all-electric injection molding machine also has two types of toggle lever type and direct pressure type, which is basically the same as the traditional injection molding machine. Because the drive system of the electric injection molding machine does not use hydraulic oil, the process parameter fluctuation caused by the possible leakage of hydraulic oil and the characteristic parameters of hydraulic oil with temperature changes are eliminated. The ball screw has higher accuracy and better repeatability, which is conducive to processing stability. The servo motor is used to control the plasticization of the screw, which has higher measurement accuracy, is more stable, and is more conducive to speed adjustment. Direct power transmission also helps to save energy. However, this type of injection molding machine uses a servo motor to drive the ball screw to drive the screw for injection. Due to the large load of the ball screw and high wear during high-speed rotation, the injection rate of an all-electric injection molding machine is generally less than 500mm / s. So work efficiency is not high.
