Abstract

PURPOSE:To quicken the response speed when the mold is opened and closed and injection is carried out, to save energy and to prolong the life of a pump, by providing a combined circuit including an accumulator and a flow rate control valve, and a circuit connected to an accumulator. CONSTITUTION:A flow rate control valve 14 is provided in a circuit 13 extending from a variable hydraulic pump 5 to a hydraulic motor 4, and a check valve 15, a proportional flow rate valve of servo valve 16 and an accumulator 18 are provided in a circuit 13a leading from a pump 5 to electromagnetic change-over valves 8, 9. In the case where the mold is opened and closed, and high response to injection is required, pressure is accumulated once in the accumulator 18, and the control is carried out by a flow rate regulating valve 16, while only in the case of plastisizing where response speed is not required, the flow control valve 14 is actuated a pressure oil in the pump 5 is sent via its pilot port 17 to a hydraulic motor 4, and the rotational frequency of the hydraulic motor is controlled by the pressure and flow rate according to the load.
