ABSTRACT:
An assembly (10) for molding a two-tone, thin-walled plastic shell (12) for parts such as automobile door panels, control and instrument panels and the like includes a charge box (24) for supplying dry thermoplastic material to separate casting surfaces (30, 32) on a heated mold (22) selectively connected to the charge box (24) during the casting process. A pressurized inflatable seal gasket (60) is connected to the charge box (24) for sealing a division surface (36) on the heated mold (22) which surface (36) separates the casting surfaces (30, 32) of the mold (22). The seal gasket (60) is attached to the charge box (24) on a divider wall (42) via a sliding member (80) which positions the seal gasket (60) longitudinally along the divider wall (42). The sliding member (80) is secured to the divider wall (42) via threaded pins (86). The gasket seal (60) may be removed and reinserted in the slider member (80) providing automatic adjustment thereof.
