Abstract: An unscrewing mechanism for forming threaded components includes at least one rotatable elongate mold core having a threaded portion at one end for molding a threaded component, a stripper plate that is separable from a stationary plate and underlying a cavity plate in which is integrated a mating mold cavity, and a drive gear with a jack screw at one end and with gear teeth that mesh with mating gear teeth on the mold core for rotating the mold core such that a movement of the stripper plate away from the stationary plate for ejecting a formed threaded component is at the same rate as the unscrewing of the mold core. The jack screw is threaded such that a riser component pushes the stripper plate at the same rate that the mold core is unscrewing.
