Claims

[Scope of Claim for Utility Model Registration] (1) A pair of lift blocks facing each other with the plate material conveyance area sandwiched from the sides are disposed on the lower surface so as to be movable toward and away from each other. In a mold device of a press machine, which is provided with a biasing means for biasing a block in a direction in which the lift block approaches, each of the lift blocks is provided with a cock opening on the conveyance area side and extending in the conveyance direction of the plate material. The step surfaces of at least two pressing bodies having a step in the direction of movement thereof are suspended from the upper die so as to come into contact with the lift block, and the width of the pressing body with respect to the lift block is adjusted. The pair of lift blocks are brought close to each other and separated in response to the rise and fall of the upper mold by the pressing force of the thick part and the thin width part, and the plate material is slid by the formed notch while the upper mold is rising. A mold device for a press machine characterized by being movably supported. (2) The mold device for a press machine according to claim (1), wherein a rotating member is pivotally supported at a contact portion of the lift block with the pressing body.
