<p>PURPOSE:To install reliably a skin material to an undercut part of a product, by a method wherein after mold clamping, resin is cast between the skin material on a bottom force side and a top force and at the time of molding of a core material integrated with the skin material, an end part of the core material is molded by squeezing the end part of the skin body into the top force by pulling the other end part of a line. CONSTITUTION:A skin material 41 is run in a stuck state along a recessed part 2 of a bottom force 1 and an end part 41a is arranged on a holding groove 3 of a clamping thread 8. After clamping, when resin 42 is cast, filled almost completely with the same by foaming and it becomes a state where a core material 43 is moldable up to an undercut part 43a an air motor 11 is driven. Then the clamping thread 8 is wound up, an end part 41a of the skin material 41 is squeezed into a recessed groove 33 of a top force 31 and presses the undercut part 43a of the core material 43. When molding of the core material 43 is completed and the air motor 11 is made free, the clamping thread 8 is restored to the holding groove 3 of four pulling-back devices 21 of the bottom force 1. Then mold is broken, the core material 3, which is integrated with the skin material 41, is taken out, an end treatment is performed and the title method is completed.</p> |
