<P>PROBLEM TO BE SOLVED: To provide an airbag cover molding method capable of realizing smooth flow of a molding material during the molding and preventing generation of dents or the like to degrade the design property. <P>SOLUTION: During the molding, a molding material M is poured in a part of a breakage scheduled part 16b on the back side of an airbag cover along the direction orthogonal to the arrangement direction of the breakage scheduled part 16b, and a shape-forming recessed part 40 of a continuous side shape-giving part 37 and a recessed part 47 of a connection side shape-forming part 44 are juxtaposed to each other along the pouring direction of the molding material M to pass the molding material M. After the pouring, the connection side shape-giving part 44 is moved to form a connection groove part 24 while a shape-giving projection part 45 of the connection side shape-giving part 44 is arranged between shape-giving projecting parts 38, 38 of the connection side shape-giving part 37, and a molded airbag cover is released and manufactured. When the breakage scheduled part 16b is pressed by an airbag and broken, a thin-walled part to connect a thin-walled part 20 formed of the shape-giving projecting part 38 to the connection groove 24 is broken. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
