。[Claims for Utility Model Registration] A mold opening/closing cylinder that moves the mold via a toggle mechanism, a hydraulic source that supplies hydraulic oil to the mold opening/closing cylinder, and the amount of hydraulic oil supplied from the hydraulic source. and a pressure control valve that controls the hydraulic pressure applied to the mold opening/closing cylinder, so that the moving speed of the mold and the mold clamping pressure are controlled by the stroke of the piston provided in the mold opening/closing cylinder. In a control device for an injection molding machine that is changed in the middle of the process, the piston of the mold opening/closing cylinder has a piston installed in a conduit provided between the mold opening/closing cylinder and the flow rate control valve. 1. A control device for an injection molding machine, characterized in that an oil amount release switching valve is sometimes connected to release a part of the hydraulic oil to the outside of the pipe.
