Abstract
A die apparatus permits the formation of an internal recess in a molded part. The die apparatus includes first and second mold members which are movable between an open and closed position. A core pin assembly includes a first core pin element and a second core pin element supported between the movable mold members for relative movement therewith. A resiliently deformable element is positioned between the first and second core pin elements. The resiliently deformable element is deformably expandable to form an external projection upon relative movement of the mold members to a closed position, and is elastically returnable upon the relative movement of the mold members to an open position.
