PURPOSE:To join a foamed resin molded product firmly to a base while reducing the cost greatly, by a method wherein after the base is arranged within a cavity of a mold, beads are filled into spaces formed on both sides of the base and the beads are heated, melted and foamed. CONSTITUTION:A base 5 is inserted into a cavity 9, supported by a pin provided on the top of a core in a standing state and mold clamping is performed by putting a top force 2 over a core 1. Spaces 8a, 8b having fixed thicknesses are formed respectively on a top 5a side and bottom 5b side of the base 5 and beads 7 comprised of granular resin containing a glass component composition is cast through a casting port 4. Then steam is introduced into a shell 3, the steam is put into the spaces 8a, 8b, heats the beads 7 filled into the spaces 8a, 8b, melts and foams the beads 7. Among the foamed resin and between the same and base 5 are welded to each other and the foamed resin molded product is molded by integrating the same on both sides 5a, 5b of the base 5. |
