ABSTRACT:
A molding apparatus and method for producing a thermoplastic lens having a minimum of stress including a male mold and a female mold defining therebetween a molding space, one of the molds being mounted for movement towards and away from the other mold, and a gate mounted adjacent to the other mold for the passage of thermoplastic resin. The other mold defines a window width for admitting thermoplastic resin to the molding space. A compression pressure applying member such as a wedge-shaped slide member is further provided for moving the other mold toward and away from the one mold so as to compress thermoplastic resin within the molding space as well as to automatically withdraw the other mold from the one mold prior to the injection of thermoplastic resin.
