    摘要： Die opening-closing means includes a servo motor and a movement conversion mechanism and is disposed between a support plate and a base stand. A movable plate is mounted on the support plate that is disposed on the base stand via a linear movement guide. In a forging cycle, die opening and closing is performed by activation of the die opening-closing means and tie bar fixing means at a rear surface side of the movable plate, and clamping force is obtained using a die clamping cylinder provided in the movable plate. When it is necessary to change over exclusive dies and change over is performed by: extending tie bar removal cylinders provided in a frame behind the movable plate so as to remove tie bars from a fixed plate; and moving a movable rail of internal rails to an open position and moving the change over carriage in along the internal rails from the outside.

    摘要： Die opening-closing means 10 includes a servo motor 11 and a movement conversion mechanism and is disposed between a support plate 8 and a base stand 1. A movable plate 4 is mounted on the support plate 8 that is disposed on the base stand 1 via a linear movement guide 7. In a forging cycle, die opening and closing is performed by activation of the die opening-closing means 10 and tie bar fixing means 21 at a rear surface side of the movable plate 4, and clamping force is obtained using a die clamping cylinder 30 provided in the movable plate 2. When it is necessary to change over exclusive dies 3b and 5b, change over is performed by: extending tie bar removal cylinders 41 provided in a frame 40 behind the movable plate 4 so as to remove tie bars 6 from a fixed plate 2; and moving a movable rail 52b of internal rails 52 to an open position and moving the change over carriage in along the internal rails 52 from the outside.

    摘要： A movable platen (4) capable of advance and retraction with respect to a fixed plate is provided with a tie bar connecting device (12) for meshing a split nut (18) with the multiple groove portion (16) of a tie bar (10), and a mold clamping cylinder (20) operable with the split nut (18) serving as a reaction force point. The mold clamping cylinder (20) comprises a primary piston (22) contacting the split nut (18) and a secondary piston (24) movable relative to the primary piston (22). It is arranged that the movable platen (4) is stopped just before the position at which the movable mold contacts the fixed mold, and in this state the split nut (18) is reliably meshed with the multiple groove portion (16). Thereafter, the secondary piston (24) and primary piston (22) are moved integrally with respect to the movable platen (4) so as to effect mold contacting and mold clamping. After molding, the secondary piston (24) and the primary piston (22) are relatively moved to effect mold release.
