It is a vertical outer edge forming chamber surface 62 that defines the outer edge portion of 56. The upper surface of the outer edge mold 60 faces the lower surface (corresponding surface) 52A of the upper mold 52, and abuts on the corresponding portion of the upper mold 52, that is, the lower surface 52A of the upper mold 52 via the skin material 16. It is a flat face-to-face 64. The lower surface 52A of the upper mold 52 is flush with the molding chamber surface 53A for molding the upper surface 26A of the flange portion 26 among the molding chamber surfaces 53.

A compression coil spring 68 is provided between the outer edge mold 60 and the lower mold 54 at each of a plurality of locations separated in the extending direction of the outer edge mold 60. Each compression coil spring 68 urges the outer edge mold 60 so that the facing surface 64 faces the lower surface 52A of the upper mold 52, that is, upward. The outer edge mold 60 maintains a horizontal posture in which the facing surface 64 faces the lower surface 52A of the upper mold 52 by adjusting the urging force applied to the outer edge mold 60 by each compression coil spring 68.

A recess 61 is formed on the outer peripheral surface of the outer edge mold 60. A stopper piece 63 that engages with the recess 61 is fixed on the lower mold 54 by a stud bolt 65. As shown in FIG. 3, the stopper piece 63 defines the upper limit position of the outer edge mold 60 by abutting on the lower end of the recess 61.

At the portion sandwiched between the front surface 64 of the outer edge mold 60 and the lower surface 52A of the upper mold 52, a phenomenon of sliding displacement toward the molding chamber 56 occurs with respect to these, and this phenomenon causes the skin material 16 to slide and displace. The back surface extending portion 30A is pressed exactly against the entire surface material mounting surface 58 of the lower mold 54 without causing slack, and the end surface extending portion 30C provides slack to the entire outer edge forming chamber surface 62 of the outer edge mold 60. It may be pressed exactly without occurring.

Then, the back surface extending portion 30A is melt-bonded (welded) to the back surface 26B of the flange portion 26 in a plane shape by the molten resin, and the end face extending portion 30C is melt-bonded (welded) to the outer end surface 26C of the flange portion 26 in a plane shape. ). These welds are indicated by reference numeral W in FIG.

These welds are clamped by sandwiching one side of the welded portion W of the skin material 16 with the upper mold 52 and the outer edge mold 60, and the other side of the welded portion W of the skin material 16 with the lower mold 54. Since it is performed in a state of being clamped by being sandwiched by the clamping member 76, the back surface extending portion 30A and the end surface extending portion 30C do not have slack due to the flow of the molten resin in the molding chamber 56, and the welding portion W does not cause slack. Welding of the skin material 16 to the resin molded product 12 is surely performed.
