Some are formed on the mold surface 52. The suction portion 51 is constituted by a small-diameter suction hole 53 penetrating from the back side of the mold surface 52 to the surface of the mold surface 52, and communicates with a suction device V such as a vacuum pump via a tube or the like. Then, the film or sheet-like flexible material 54 is suction-held on the mold surface 52 by the suction of the suction device V.

外観が損なわれ易かった。However, the structure of the conventional suction unit is such that a film or sheet-like flexible material 5 is formed through one small suction hole 53 formed in the suction unit 51.
4, the suction force is not sufficient and the mold surface 5
In some cases, the film or sheet-like flexible material 54 may shift and wrinkle during closing or foam molding depending on the shape and the like of No. 2. In particular, as shown in this figure, the film or sheet-like flexible material 54 is formed into a predetermined shape, and then the periphery thereof is cut in accordance with the product shape. In this case, the edge of the flexible material 54 was not pinched by the parting surface of the mold, so that the flexible material 54 was easily fallen, and the appearance of the obtained resin molded product was easily damaged.

Holes are drilled from the surface side of No. 2; however, since the mold surface 52 is made of a hard material in terms of strength and has a sufficient thickness, it is difficult to say that drilling is easy. Moreover, in order to make the film or sheet-like flexible material 54 to be suctioned well, it is preferable to open the suction hole 53 perpendicularly to the mold surface 52. However, the mold surface 52 has a size and a shape corresponding to the product. Since there is also a curved surface portion in addition to the flat portion, when the drill blade is applied to the mold surface 52 of the suction portion 51 perpendicularly, a part of the drill hits another portion of the mold surface, and Often the blade cannot be vertical.
