An improved injection molding apparatus for molding snap-on, thermoplastic air bag covers is provided including a plurality of wedge-shaped outboard mold parts slidably mounted on bearing surfaces of a plurality of gibs which are removably mounted to a central wedge all nested together within a central recess in the lower mold half in retracted positions of the outboard mold parts. Each of the outboard mold parts has a clip member-defining surface for forming front and rear sections and a snap-on groove of its corresponding clip member of the air bag cover. Each outboard mold part is in sliding contact with its respective gib during its entire sliding movement between its retracted and fully extended positions.
