Abstract

In a method and system of controlling an injection molding machine in which molten metal in an injection cylinder is injected into a metal mold by an injection plunger operated by an oil pressure operator and in which pressurized oil is supplied to the oil pressure operator through adjustable valve means actuated by actuator means, various factors relating to an injection condition are measured and an injection command signal is calculated based on the measured factors for providing a predetermined injection pattern. The actuator means is operated by the injection command signal so as to adjust the adjustable valve means to a degree of opening necessary to establish an optimum injection condition.
