APPARATUS FOR MANUFACTURING LENS AND MANUFACTURING METHOD USING THE SAME

摘要

PURPOSE: A lens molding apparatus is provided to increase size accuracy of a lens shape and to minimize void formation in lens by discharging whole air of a chamber before supplying a material into the chamber of a lens mold. CONSTITUTION: A lens molding apparatus comprises a lens mold(200) and a vacuum molding unit(100). The lens mold comprises a connecting portion(240) at one side. The lens mold is mounted at a light-emitting surface side of a light-emitting means. The vacuum molding unit discharges air inside the lens mold to the outside or injects a material to the inside of the lens mold through the connecting portion. The vacuum molding unit comprises a body unit(110) and a material feeding portion(111). The body unit comprises an air discharge portion(121) of which one end is connected to the connecting portion. The material feeding portion is mounted inside the body unit. The lens mold comprises a convex part(220) and a plate part(230). At least one excessive material accommodating groove(260) is formed in an inner periphery of the lens mold.
