    摘要: Gas (air) is supplied into an oil transfer line extending between a front oil chamber of an injection cylinder and an oil tank during a molding cycle, excluding an injection step, thereby preventing impact which would otherwise occur due to oil pressure generated upon start of injection in the injection step. Thus, immediately before the start of the injection step, the oil transfer line becomes empty of or almost empty of oil. Accordingly, even when high-pressure oil is supplied into the injection cylinder in an impactive manner upon start of injection, pressure oil ejected from the injection cylinder flows swiftly through the oil transfer line.

    摘要: Disclosed is a hydraulic drive system of an injection molding machine which has a hydraulic power source equipped with a fixed-displacement hydraulic pump and a servomotor for driving the hydraulic pump and functioning to control discharge rate and discharge pressure of the hydraulic pump through control of the rotational speed of the servomotor. In the hydraulic drive system, a pilot port of a control valve connected to a hydraulic actuator of the injection molding machine is connected to a supply line of working fluid discharged from the hydraulic power source, via a series circuit including a check valve for preventing backflow from the pilot port and a changeover valve.
