IPC: B29C48/90
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To provide a promoting method for foaming of expanded synthetic resin moldings in which an accurate outer shape and a good skin layer are formed and furthermore internal foaming nonaffecting the outer shape is sufficiently achieved by only eliminating a volume reduction member after the skin layer is formed. SOLUTION: Until a fluid raw material 6 forms a skin layer 6a in the extrusion hole 7 of a die 2, foaming of the raw material 6 is inhibited by allowing a volume reduction member 9 of the extrusion hole 7 to exist. After the skin layer 6a is formed, the volume reduction member 9 is eliminated and a decompressed cavity 10 is formed on the rear side thereof and foaming of the raw material 6 is promoted. Further, the skin layer 6a is formed even in the part coming into contact with the volume reduction member of the raw material 6 by cooling the volume reduction member 9 allowed to exist in the extrusion hole 7 of the die 2 through a cooling means. The skin layer 6a is crushed and moved by foaming of the raw material 6 and a reinforcement core 12 is formed.
