PROBLEM TO BE SOLVED: To perform simultaneous control of a plurality of actuators by a single variable pump and to shorten the molding cycle of an injection molder. SOLUTION: This control device comprises a variable pump 11; a plurality of actuators; control valves disposed corresponding to the respective actuators and controlling an oil pressure fed to the actuator; a variable pump control valve 81 to control an amount of oil discharged from the variable pump 11; and a valve opening control means to control the valve openings of the control valve and the variable pump control valve 81 independently from each other. In this case, since the valve openings of each control valve and the variable pump control valve 81 independently from each other, a plurality of the actuators are simultaneously actuated. This constitution shortens the molding cycle of an injection molder. |
