Abstract
When controlling each operational process in a molding cycle by variably controlling the number of revolutions of a drive motorin a hydraulic pump, a hydraulic pumpwhere at least multiple fixed discharge flow rate Qo and Qs can be set is used as the hydraulic pump. At the same time, the fixed discharge flow rates Qo . . . are set corresponding to operational processes based upon predetermined conditions in advance, respectively, and the hydraulic pumpis switched to the fixed discharge flow rates Qo . . . by corresponding to each operational process at the time of molding. At the same time, each operational process is controlled by variably controlling the number of revolutions of the drive motor
