Abstract
A molded disk is transferred out of the mold with short-stroke low-mass motions of a pair of mechanical guides which can grip, then release, the O.D. edge of the molded disk, when acting in coordination with movable mold members having undercuts for molded-on retention of the inner portion of the molded disk and/or sprue. Acting together, the disk is stripped off the molding surfaces and can be oriented in a second vertical plane to freely drop out an aperture in the mold, to exit through a discharge chute. Two ways of separating the sprue from the disk are shown, with a molded-in centerhole being preferred. This method and apparatus for transferring the molded disk out faster by gravity discharge wherein an optical disk mold can be enclosed against airborne dirt throughout molding cycles.
