Abstract
A clamping apparatus of an injection molding machine includes a servo motor installed at the center of the rear platen and two timing belts to drive two ball screws so as to push a five point inwardly bending toggle mechanism to open the mold, close the mold and mold clamping. Moreover, a servo motor is fixed to the lateral side of the movable platen to drive the nuts of the screw to rotate so as to push the ball screw, ejector rod and ejector plate to move linearly for achieving the object of ejecting. An electromotive motor on the rear platen will drive the mold adjusting means. By the assisting of the servo motor on the rear platen, the function and object of automatic mold adjusting can be achieved rapidly.
