Abstract:
A molding apparatus can include a primary mold, a stripper, and a swinging member. The swinging member can comprise a molding surface defining an undercut portion of a molded item. The swinging member can directly contact or attached to the stripper and the primary mold. To facilitate removal of a molded item, the swinging member can withdraw through a hole in the primary mold as a direct result of a motion of the stripper to pull the molded item off the primary mold. The molded item can then be easily removed.
