Abstract

The multistep injection molding device is for manufacturing thick lenses for use with an illumination apparatus. The injection molding device includes two sets of mold core inserts forming mold cavities when the injection molding device is in a closed position. The lens core part is formed in a first injection shot station. The molded lens core part is then moved to a post-molding cooling station in which it is further cooled inside a corresponding mold cavity. Two outer lens parts are formed sequentially over the lens core part in second and third injection shot stations. A method of manufacturing a thick lens is also disclosed.
