Claims

[Scope of utility model registration request]

The cross section of the panel work is approximately double crank shape (-low shape)
In a press mold for press molding, a pad is elastically supported so as to be able to move up and down on either an upper mold or a lower mold that approaches and separates from each other, and the pad is sandwiched between the pads on both sides of the pad and is pressed against each other. a pair of collapse cams disposed to face each other and supported by the one type so as to be movable back and forth with respect to the pad; a pair of movable gougs supported so as to be movable relative to each other; a punch attached to the other mold so as to face the pad and having a pressure surface having a double crank shape (-mouth shape) in cross section; A first cam part provided in the other mold and for retracting the collapse cam including the movable die by slidingly contacting the collapse cam in response to the approaching movement of the upper mold and the lower mold; A second cam part is provided on the mold and slides into contact with the movable die after the collapse cam retreats in response to the approaching movement of the upper mold and the lower mold to advance only the movable goo. Press type.
