Zusammenfassung:	PROBLEM TO BE SOLVED: To improve the workability of mold opening when an elastic molded article is molded in a mold for molding. SOLUTION: An air intake hole 8 provided in a mold 3 is made under closed condition until a molding material 14 is solidified but is made under opened condition after the molding material 14 is solidified. Pressurized air is fed into a cavity 12 from this opened air intake hole 8 to open the mold while an elastic molded article is elastically bent and the air is made to flow into the gaps of the molding faces 7 and 11 of the cavity 12. Therefore, as the pressurized air is made to flow between the molding faces 7 and 11 of the cavity and the elastic molded article, there exists no possibility of acting of back pressure when the mold is opened and therefore, it is possible to open the mold only by human power without using such a tool as a bar.
