Abstract
A mold for shaping a skin sheet has a three-dimensional body including a top surface and side surfaces that work as a shaping surface, respectively. The top surface and the side surfaces have a plurality of small holes communicating with a suction unit for drawing the skin sheet thereon by suction force generated by the suction unit. Each of the side surfaces has a product portion and a non-product portion parted at a trimming line, the portions corresponding to those of the skin sheet that are used as a product and not used as the product, respectively. The body has a plurality of guidance plates, each projecting outside at an edge line of the body. An upper edge of each of the guidance plates forms a ridge line in a shape of a wave. The ridge line descends from a position in the vicinity of an intersection point of the edge line and the trimming line to a direction of the bottom of the body so as to form a valley and thereafter ascends to an opposite direction so as to form a mountain. The height of the deepest point of the valley is lower than that of the trimming line.
