<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a vacuum suction molding die capable of forming innumerable micro-vent-holes with a diameter of about 0.3 mm not obtained by drilling, in a die inner wall of a lower die, and of exhibiting excellent appearance quality in an integral foam molding with a skin, even when using, for the skin, a skin material such as a thick-piled fabric, a short-piled thin cloth with substantially little pile and a vinyl leather. <P>SOLUTION: Upper and lower molding dies 22, 23 are arranged with a prescribed space to form a cavity 26 therebetween, innumerable wire rods 28 are laid at a proper interval between the upper and lower molding dies 22, 23 in an inside of the cavity 26, a resin material is injected into the cavity 26 and is cured to form the molding in correspondence to a shape of the cavity 26, the innumerable wire rods 28 are extracted from the molding after molded, and the innumerable micro-vent-holes are penetrated through in the molding, to allow vacuum suction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
