Claims

[Scope of utility model registration request]

The press device includes an upper mold and a lower mold that are arranged opposite to each other so as to be close to each other or to be separated from each other along the pressing force loading direction, wherein the upper mold has a front end surface facing in the pressing force loading direction that is connected to the upper mold first. One of the two side surfaces located in a direction orthogonal to the press force loading direction is used as a molding surface, and one side surface is used as a second molding surface of the upper mold that is substantially orthogonal to the first molding surface of the upper mold, and the other side surface is shaped like an arc. The lower mold has a guide surface composed of a circumferential surface, and is movable around a fulcrum pin that is orthogonal to the press force loading direction. While the first molding surface is a surface that is continuous with the first molding surface of the lower mold and faces the second molding surface of the upper mold in a direction orthogonal to the press force loading direction, a press force is applied from the first molding surface of the lower mold. A second molding surface of the lower mold is formed of an inclined surface that gradually separates from the upper mold in a direction perpendicular to the press force loading direction as it moves away from the upper mold in the loading direction, and the upper mold is further moved in the swinging direction of the upper mold. At a position where the second molding surface of the upper mold is opposed to the second molding surface of the lower mold, the second molding surface of the upper mold is brought into surface contact with the guide surface of the upper mold as the upper mold and the lower mold approach each other. A press device characterized in that a back-up is provided with an arc-shaped guide surface that presses against the second molding surface side of the mold.
