PURPOSE:To contrive a reduction in man hours and improvement in reliability by fitting a skin material to a foam mold simply and accurately, by a method wherein a mold part coincides with a part obtained by joining a skin material to a skin end fitting member is formed on the fringe of the upper part of the inner mold part of a bottom force, the skin material is stuck to the inside of the bottom force and the skin material and urethane mold are foamed unitarily by casting foamed raw materials. CONSTITUTION:O-P-Q parts of a skin material 1 fitted to a fitting member 3 of a terminal of the skin material is bent and fitted after a bottom force 6. The terminal part of the skin material 1 is positioned between O-P parts of the bottom force 6, and a, top force 8 is inserted into the skin material by descending the top force 8, In the case where the fitting member 3 of the terminal of the skin material has elasticity, the same is fitted by pressing the same against the bottom force 6. Then urethane foam raw materials are either foamed by casting the same through raw material casting port 8a or foamed by the top force 8 heaving no raw material casting port 8a by casting the urethane raw materials into the bottom force. In the case where a casting and foaming method is of neither high pressure nor a high speed, a heat-meltable film is put on the skin or a wadding on which the urethane raw materials are cast and foaming is performed by inhibiting impregnation. Then the heat-meltable film is melted and the urethane and the skin or the wadding are stuck together. |
