Claims

[Scope of utility model registration request]

The workpiece placed on the lower mold is pressed by a pad elastically supported on the upper mold side, and the lower mold cooperates with a slide cam that is driven based on the movement of the upper mold and lower mold toward and away from each other. This is a device that applies auxiliary pressing force by pressing the pad from the side when flanging the end of the workpiece, and the pad is pressed against the side of the pad and the vertical wall of the slide cam and compressed and deformed when they are pressed against each other. A pad pressure increase device for a press molding machine, characterized in that cylindrical rubber-based elastic bodies are individually attached.
