Abstract
In a method of controlling an injection molding machine M which controls specified operational processes in a molding cycle by variably controlling the rotation speed of a driving motor 3 in a hydraulic pump 2 and driving a specified hydraulic actuators 4a, 4b, . . . , in lowering the pressure Pd of the operational process to a specified pressure Pn, the pressure Pd is forcibly lowered by controlling the driving motor 3 in reverse rotation.
