ABSTRACT:
A mold for forming an article having one or more substantial radial protrusions. The mold includes a core movable along a molding axis, a stripper ring movable a limited distance along one set of guide rods with axes parallel to the molding axis, a split ring having segments movable adjacent to the stripper ring for the limited distance and movable relative to the stripper ring on a second set of guide rods at an angle to the molding axis, and a cavity. The article is removable from the mold when the core is moved away from the cavity, the stripper ring is moved its limited distance, and the split ring segments are moved with the stripper ring and then relative to the stripper ring at an angle to the molding axis.
