Zusammenfassung:	PROBLEM TO BE SOLVED: To achieve the enhancement of energy saving properties, the reduction of a running cost and the reduction of the initial cost of the whole, achieving the enhancement of moldability and molding quality, the enhancement of reliability, and the extension of life. SOLUTION: In this injection molding machine, the number of rotations of the drive motor 3 in a hydraulic pump 2 is variably controlled and, when the respective operation processes in a molding cycle are controlled, the hydraulic pump 2 capable of setting at least a plurality of fixed discharge flow rates Qo and Qs is used to preset the fixed discharge flow rate Qo corresponding to each of the operation processes on the basis of a predetermined condition. At the time of molding, the hydraulic pump 2 is changed over to the fixed discharge flow rate Qo corresponding to each of the operation processes and the number of rotations of the drive motor 3 variably controlled to control each of the operation processes.
