INJECTION MOLDING MACHINE, HYDRAULIC ACTUATING MECHANISM OF INJECTION MOLDING MACHINE, AND CONTROL METHOD THEREFOR |
摘要 |
The present invention provides a hydraulic actuating mechanism of an injection molding machine, in which a plurality of hydraulic actuators are driven by one hydraulic pump, wherein the hydraulic pump of the hydraulic actuating mechanism is a variable discharge pump having the maximum necessary delivery capacity at least for each of the hydraulic actuators at the time of the highest rotational speed of the pump; the discharged fluid pressure is controlled by a discharge cutoff function of a pressure compensator ancillary to the variable discharge pump; and the pump is driven by a motor whose rotation can be controlled in a stepless mode.
