PURPOSE:To cover easily and swiftly an open part of a skin material with a back cover part after molding of a foam, by a method wherein an end of the back cover part is connected with the skin material, a holding part closed up tightly with mold register between a bottom and top forces is formed on the outside of the side of the bottom force and the back cover part is held into the holding part. CONSTITUTION:A skin material 22 is arranged on a bottom force 12, a back cover part 24 connected with the skin material 22 is held within a holding part 18 through the top of the side 15 of the bottom force 12 and a core mold 14 is fitted to the bottom force 12. A top force 13 is mold-registered to the bottom force 12, an upper open part 19 of the holding part 18 is made into a closed state with an end part 31 of the top force 13, a stock solution of foamed synthetic resin is poured through a pouring port 32 formed into the top force 13 and a foam 35 is formed integrally with the skin material 22. When the top and bottom forces 12, 13 are broken, the core mold 14 is removed, a monolithic foam 21 of the skin material is taken out through the bottom force 12 and the back cover part 24 is fitted to the back open part 23 of the skin material 12 through fasteners 25a, 25b, the monolithic foam 21 of the skin material can be obtained. |
