PURPOSE:To hold part of a formed piece on a top force and to strip it off from a bottom force when the top and bottom forces are separated by providing a grip for holding part of forming material at one side end of the top force in time of pressure molding. CONSTITUTION:Top and bottom forces 4a, 4b are opened, a formed piece (a) is allowed to attach to the bottom force 4b to supply the material. The top and bottom forces 4a, 4b are closed, a pressure member 3 is moved upward and pressure-molded. The grip 5 abuts with a pressure receiving member 2, a clearance is created between the lower surface of the top force 4a and the grip 5 to allow part of the material to come in. After molding, if the pressure member 3 moves downward mounting the forming force 4 on the pressure member 3, part of the formed piece (a) is held between the lower surface of the top force 4a and the grip 5. Then, when the top force 4a is fed by a piston cylinder 12 on to a work table 11 and is separated by a pushing piece 15 from the bottom force 4b, the formed piece (a) is stripped from the bottom force 4b. By advancing an extractor 17 the formed piece (a) is received on a supporting table 19. |
