。[Claims for Utility Model Registration] (1) A pressure dome connected to a control unit having a hydraulic pressure intensifier, a slide having a male mold pushed into the pressure dome and lowered by a main pressure cylinder, and a molding A press for hydro restriking, characterized in that it is equipped with a pressurization holding means that increases the descending force of the slide at the final stage to maintain the pressurizing force at the bottom dead center of the male mold. (2) A pressure holding means that increases the descending force of the slide at the end of molding to maintain the pressure at the bottom dead center of the male mold is a pressure holding cylinder provided on the press frame, and this pressure holding cylinder. A utility model registration claim 1 comprising: a pressure holding ram extending from the pressure holding ram to the slide; and a stopper mechanism provided in a relationship intersecting the axis of the pressure holding ram and transmitting the downward force of the pressure holding ram to the slide. Press for hydro restriking as described in section. (3) The press for hydrorestriking according to claim 1, wherein the pressure intensifier is in the hydraulic control circuit. (4) The hydro restrike according to claim 1 of the utility model registration claim, in which a pressure intensifier is disposed below the slide, and uses the descending force of the slide to compress the liquid and send it into the pressure dome. press.
