초록

A shot cylinder controller for injection molding machines comprises a valve connected with one side of the shot cylinder and including a valve head which is movable with respect to a seat. The valve head is connected with at least two, lineally extensible actuators, interconnected in an end-to-end relationship. The actuators are independently extended and retracted, whereby selective manipulation of the actuators varies the position of the valve head, and thereby controls the extension of the shot cylinder and regulates the speed of die injection.
