<P>PROBLEM TO BE SOLVED: To improve flexibility to controllability and widen the control range by combination of control conditions, thereby to perform appropriate control with respect to various molding modes, too. Ž<P>SOLUTION: When performing control on respective operation processes in molding cycles, by driving to rotate a pump body 3 by a first driving motor 4, making the rotation speed of the first driving motor 4 variable, and variably controlling at least the first driving motor 4 for a hydraulic pump 2 variable in discharge flow rate; by rotation amount of a second driving motor 13 in a swash plate angle variable mechanism 12 utilizing the second driving motor 13, at least the angle (swash plate angle) of a swash plate 11 in a cam (swash) plate type axial piston pump 2s variable in discharge flow rate is made variable, and the operation processes are controlled based on the combination of a first control condition preliminarily set to the rotation speed of the first driving motor 4, and a second control condition preliminarily set to the rotation amount of the second driving motor 13.
