摘要:
In a hydraulic drive device (1) for an injection molding machine (M) that has a pressure control valve (Vs) incorporating a pressure sensor (2) for detecting a hydraulic pressure and a feedback control circuit (Cs) for controlling the hydraulic pressure by feedback based on a pressure detection value (Spd) obtained from the pressure sensor (2) and a pressure instruction value (Spc) fed from a molding machine controller (3), the molding machine controller (3) includes a second feedback control circuit (Cm) for correcting the pressure instruction value (Spc) that is fed to the pressure control valve (Vs) based on the pressure detection value (Spd) fed from the pressure control valve (Vs) and the pressure instruction value (Spci) obtained from the interior of the molding machine controller (3).
