Abstract: Disclosed is an injection molding process control method of a multi-color injection molding machine, and its automated process setting includes a mold-opening ending process setting and a mold-closing ending process setting. The mold-opening ending process setting includes a multiple of action options sequentially carried out after a setting is selected from the mold-opening ending automated process option, and the mold-closing ending process setting is a setting selected from the mold-closing ending automated process option according to each switching action, so that the multi-color injection molding machine can use a page of the automated process setting together with the desired action option to click and select a setting according to different injection molding objects or molds, so as to complete the correction and setting of the injection stroke quickly and improve the operational efficiency of the injection molding.

Abstract: A rotary-shaft type turntable positioning method of an injection molding machine is disclosed. A first encoder and a second encoder are installed at a driving shaft of a servomotor and a speed reducer respectively, so that after the injection molding machine finishes an injection molding, the driving shaft of the servomotor drives a transmission belt on an output shaft of the speed reducer to rotate a rotary shaft for the turntable to be rotated and positioned. During rotation, the first encoder and the second encoder sense a first rotation signal and a second rotation signal to adjust the position, so as to control the turntable to be rotated to a precise position.

Abstract: An electrical mold clamping apparatus of a plastic injection molding machines includes a motor unit mounted onto a link base for driving a gear at an end of a ball screw in the link base to rotate and a ball screw socket disposed at a fixed base, and the other end of the ball screw of the link base is screwed into the ball screw socket. When the motor unit drives the ball screw to rotate, the link base is displaced with the rotation of the ball screw to achieve the effect of reducing the load of the motor unit as well as the loss of energy.

Abstract: A rotary-shaft type turntable positioning device of an injection molding machine includes a first encoder and a second encoder installed at a servomotor of a positioning device and a speed reducer respectively, so that after the injection molding machine finishes an injection molding, the servomotor is used to drive the driving shaft and link the output shaft to drive the driving wheel to rotate a rotary shaft, while rotating and positioning a turntable. During rotation, signals of the first encoder and the second encoder are sensed to adjust the position, so as to control the turntable to be rotated to a precise position.
