A forging die for producing cylindrical objects, having undercut flanges, comprising a lower die having an embossing insert therein; a motor-driven upper die movable towards said lower die; actuating means subdivided in a vertical plane into two actuating elements which define with an upper limiting surface of the embossing insert an embossing groove receiving a blank, said actuating elements being horizontally movably driven between an open position and a closed molding position; at least one locking member for locking said actuating elements in said closed positions; hydraulic piston-cylinder units adapted to act on at least portions of the at least one locking member, said hydraulic piston-cylinder units being loadable at both sides with pressure of a pressure medium and with said actuating elements being movable between the open and closed position by said piston-cylinder units; unlocking means acting on an underside of said locking member and being motor-driven to move in a vertical plane; a push rod for pushing a forged object away from said embossing groove and actuated by said unlocking means; and wherein each of said actuating means has an outer conical surface, said locking member has a conical inner surface cooperating with the conical surface of each actuating element so as to releasably engage the same.
