초록

A molded foam article with an integral skin is produced by blow-molding a parison in a cavity of a metal mold to form a hollow member, filling the hollow member with pre-expanded thermoplastic resin besides before cooling and solidification of the hollow member, and heating the pre-expanded beads to cause the beads to expand further and fuse together. A filler for the pre-expanded thermoplastic resin beads is provided with a cutter for making a hole in the hollow member before introducing the resin beads into the hollow member.

청구항

A method of producing a molded foam article with an integral skin in a cavity of a mold having a parting line plane comprising the steps of: blow-molding a parison suspended in a blow-molding metal mold to form a hollow member; cutting a hole in said hollow member in registry with a drivable cutter slidably and rotatably fitted within a bore which opens into the cavity of said mold at a location other than the parting line plane of said mold, said drivable cutter being a frontal part of a filler for pre-expanded thermoplastic resin beads and being extend...
