    摘要： A velocity-pressure switching and pressure holding device and system for electrically-operated injection molding machines. The switching between closed-loop position control and closed-loop pressure control of a servo motor of an injection molding machine is quickly and smoothly achieved by a switchable loop switch to ensure the optimal control of the velocity-pressure switching during injection filling and pressure holding. Furthermore an adjustable observation value and a speed reducing set up for the injection axle before switching are provided to allow users to perform minor adjustments on the velocity-pressure switching during the slow down of the injection axle. The present invention easily and precisely achieves the optimal velocity-pressure switching parameters to facilitate better pressure holding ability to increase the quality of the plastic products.

    摘要： An injection molding machine includes a cylinder; a screw; a rotary driving unit; a reciprocation driving unit; a pressure detector that detects a pressure of a molding material in front of the screw; a control unit that performs a first type of plasticizing process where the screw is moved backward to a predetermined position and rotated at the predetermined position to transfer the molding material forward to reserve the molding material in front of the screw, performs a first type of filling process where the screw is moved forward to inject the molding material reserved in front of the screw in the first type of plasticizing process from the cylinder to be filled in a mold unit, monitors the pressure in the first type of filling process by the pressure detector, and corrects the setting of the first type of filling process based on a monitored result.

    摘要： A hybrid injection unit for an injection molding machine includes a plasticizing screw having a shaft and constructed for rotation and axial displacement. Operatively connected to the shaft is a first electric motor for rotating the plasticizing screw, and a second electric motor for axial displacement of the plasticizing screw. A cost-efficient construction of the second electric motor and reduced stress of the linkage between this electric motor and the shaft is realized by providing at least one piston and cylinder unit in fluid communication with a pressure source for support of the second electric motor in injection direction, and a traverse acted upon by one end of the piston and cylinder unit and rotatably supporting the shaft of the plasticizing shaft. The traverse acts upon the shaft between a force introduction point of the second electric motor into the shaft, on one hand, and the plasticizing screw, on the other hand.
