Abstract
An injection mold and a cooperating molding system and method that allows for the parting line of a molded vehicle bumper fascia to be hidden within the wheel arch portion thereof. The invention contemplates two different mold designs for producing such a parting line: a double-lifter design and a collapsing slide core design. The bumper fascia remains in the cavity portion of the mold after molding due to the presence of undercuts in the mold cavity. A robotic part removal device is used to remove the molded bumper fascia from the mold cavity after mold opening. The part removal device is adapted to temporarily deform the bumper fascia in the wheel arch flange areas thereof to facilitate its removal from the cavity.
