摘要： A molding apparatus is provided which comprises a lower mold portion and an upper mold portion movable into engagement with the lower portion. A movable spray head is disposed on a traversing rack mounted within a retractable coating box. The coating box upper surface contains a first opening corresponding in size and shape to the outer periphery of the mold cavity of the upper mold and a second opening which corresponds in size and shape to the opening of an overspray recovery transition piece disposed at a position adjacent the fully disengaged upper mold portion. Prior to a molding operation, the coating box engages the upper mold permitting both the transition piece opening and cavity opening in the top surface of the box to align with the transition piece and cavity, respectively. The spray heads and drive of the traversing rack are activated and the overspray recovery transition piece fluidly communicates with an evacuated recovery booth, thereby causing the cavity of the upper mold to be coated and the overspray to be withdrawn into the recovery booth.
