Abstract

PURPOSE:To obtain a molded article which is hinged so that mounting parts can be turned over on the main part of a cushion by a method wherein netlike hinge materials are prepared on the pivots of common walls, molds are shut, original liquids different in the composition of foam resin are injected for foam-molding into a lower mold body and side lower molds respectively. CONSTITUTION:A mold 8 is composed of a combination lower mold 4 on which the lower mold body 1 for the main part A of a combined cushion body C in the desired form of a seal and the like and the side lower molds 2 for conbination mounting parts B that are turnover on the lower mold body are connected through common walls and the combination upper mold 7 on which stop pins 6 of netlike hinge material 5 such as Victoria lawn are laid. The original liquids A', B' different in the composition of resin foam material are injected into the lower mold body 1 and the side lower molds 2 respectively and the upper mold on which the said hinge material 5 is set temporally to the pins 6 is mounted on the lower mold to close the molds. When putting one side of the hinge material 5 in the lower mold body 1 and the other side thereof in the side lower mold 2, the original liquids are made to foam and age and then these molds are opened, one can obtain the combined cushion body C in which the hinges are laid in a unitary body so that the mounting parts B can be turned over on the cushion body A through the hinge materials 5.
