Air bag cover body forming apparatus

摘要

An apparatus for forming air bag covers includes mold portions (2A, 2B), a grooving blade (3), and a supporting rod (4). The mold portions form a cavity (20) for molding a resin air bag cover (1) provided with an air bag door. The grooving blade forms a break groove (11) defining the air bag door at the air bag cover. The supporting rod supports the air bag door of the air bag cover molded in the cavity. The molding apparatus includes movable cores (21a, 21b) reciprocally movable between a position where the core contacts the air bag cover and a position where the core is separated from the air bag cover. The supporting rod comes into contact with the air bag door when the core is separated from the air bag door, thereby preventing stress concentration on the break groove.
