PROBLEM TO BE SOLVED: To provide an injection molding machine which enables parallel operation, including screw rotation, of a plurality of actuators not requiring the increase of electric capacity. SOLUTION: The injection molding machine is configured so as to operate in the following way. At least, a screw 15 is driven to rotate by a servo motor 14, and a hydraulic actuator 10 other than the servo motor 14 is driven by hydraulic oil cumulatively pressurized in an accumulator 9. When the servo motor 14 rotates to drive the screw 15, the actuation of the accumulator 9 for pressure accumulation is prohibited. COPYRIGHT: (C)2008,JPO&INPIT |
