PROBLEM TO BE SOLVED: To provide a manufacturing method of molding an internal equipment body of automobile whose cover body part for rupture of an airbag is integrally formed of a hard resin material which does not have an apparent pressed mark of a groove forming member on its surface (a designed surface) side. SOLUTION: In the manufacturing method of molding the internal equipment main body of automobile, cover body part for rupture of the airbag is integrally formed of the hard resin material. When molding, a cover body part 16, a tear line shaping block 24 with protruding parts 22 for tear line forming corresponding to tear lines (rupture expecting fragile part) 18 and 20 for the cover body part 16 moves forward to form the tear lines 18 and 20 in a state that the material has fluidity after charging. In this case, the temperature of a metal mold of outside shaping surface (a female mold 30) on the opposite side to the groove shaping block 24 side should be higher than that of the groove shaping block 24. |
