MOLD FOR MOLDING EXPANDED RESIN AND PROCESS FOR PRODUCING SAME

A mold for molding an expanded resin, wherein a silicone rubber layer (40) having a JIS-A hardness of 20 to 70 is formed as a heat-insulating layer at least on a part or the whole of the inner wall surface that forms a cavity (20) of a mold main body (10) which is for use in molding an expanded resi...

Beschreibung
Zusammenfassung:	A mold for molding an expanded resin, wherein a silicone rubber layer (40) having a JIS-A hardness of 20 to 70 is formed as a heat-insulating layer at least on a part or the whole of the inner wall surface that forms a cavity (20) of a mold main body (10) which is for use in molding an expanded resin and which is made of an aluminum material. This mold for molding an expanded resin is effectively usable in molding expanded polystyrene or the like by a bead molding method, and can produce a molded product of an expanded resin with high thermal efficiency by virtue of high heat insulation performance. Further, the mold can be easily produced with good execution efficiency.
