Abstract

PURPOSE: To obtain a cushion body efficiently without the need of deburring by placing in advance a sheet-shaped cushion body in a split mold composed of plural mold component members, in such a manner as to bridge the joint portions between the members, injecting a foamable solution into the mold, and foaming the solution.
CONSTITUTION: A sheet-shaped cushion body 3 is placed along the inside surface of the lower mold 1 of a split mold A composed of lower and upper molds 1 and 2, with the end portions of the cushion body 3 extended up slightly beyond the brim portion 1a of the lower mold 1. After a foamable solution 4 of a synthetic resin is flowed onto the cushion body 3, the mold 1 is covered with the mold 2, and the solution 4 is foamed, to integrate a foamed body 5 of the solution 4 with the cushion member 3 and to yield a cushion body molded in accordance with the inside shape of the mold A under the foaming pressure. As the foamed body 5 is prevented from penetrating into the joing portion between molds 1 and 2 by the cushion member 3, the thus obtained cushion body is free of burrs.
