Due to the effect of atmospheric pressure, the sucked injection molded part will be subjected to a pressure toward the surface of the vacuum suction cup 42, so that it is sucked and fixed on the vacuum suction cup 42, realizing the rapid grasping and releasing of the injection molded part.

[0033] The forward and reverse motor 51 is started by the controller, so that the worm 52, the rotating shaft 53, the worm wheel 54 and the mounting plate 55 are transmitted and cooperated, and the working direction of the manipulator is quickly changed, thereby rotating and switching the four fixing mechanisms 4 for simultaneously grasping and releasing the injection molded parts, realizing simultaneous picking and placing of the injection molded parts, improving work efficiency, and improving the efficiency of taking and placing the injection molded parts and the convenience of operation.
