PURPOSE:To enhance the efficiency of molding work by accurately embedding a part to be embedded in a foam layer at a predetermined position, by placing the part to be embedded on a primary foam layer and molding a secondary foam layer thereon. CONSTITUTION:A foamable raw liquid is injected in the space between the first and third molds 2, 4 and solidified to form a primary foam layer 5. The third mold 4 is removed and a part 6 to be embedded is placed on the recessed part 5b formed to the primary foam layer at a predetermined position. Subsequently, the fourth mold 7 being an upper mold for molding a secondary foam layer is set to the first mold 2 to clamp both molds. The foamable raw liquid is injected in the space between the primary foam layer 5 and the fourth mold 7, and foamed and solidified to form the secondary foam layer 8. The part 6 to be embedded is held between the primary and secondary foam layers 5, 8. The first and fourth molds 2, 7 are removed to obtain a resin foam having the part 6 to be embedded accurately embedded therein at a predetermined position. |
