Abstract A method for controlling implements by means of a hydraulic pressure. A hydraulic pressure is fed from an accumulator to a first hydraulic circuit, after the operating pressure has been once lowered any arbitrary operating pressure or variation of the operating pressure is detected in the course of restoration to an initial set pressure, and a second hydraulic circuit is triggered by a detection signal based on this detection. In a secondary pressurization casting process to which this hydraulic control method is applied, when molten metal within an injection sleeve is filled under pressure within a cavity of a casting mold by means of an injection ram driven by an operating pressure of an accumulator, the injection ram is made to advance initially at a low speed and subsequently at a high speed, and while the introduction of the accumulator operation pressure to a hydraulic cylinder for driving the injection ram is sustained, a pressurizing rod is actuated after completion of filling of molten metal to make a secondary pressurizing force exert upon the molten metal. The operating pressure of the accumulator continues to lower in the course of advancing of the injection ram, and it begins to restore after the filling of molten metal into the cavity of the mold has been completed. Any arbitrary operating pressure or variation of the operating pressure in the course of restoration of the operating pressure is detected, and a hydraulic circuit for driving the pressurizing rod is triggered on the basis of the detection signal to make the pressurizing rod advance into the cavity.
