MOLD ASSEMBLY FOR FOMRING OPTICAL LENS FOR LED

摘要

A mold assembly for manufacturing an optical lens for LED, includes an upper die, an upper die core received in the upper die, a bottom die and a bottom die core received in the bottom die. The upper die core includes a bottom surface; the bottom surface has a profile corresponding to a profile of a top portion of the optical lens. The bottom die includes a base and a replaceable die core removably received in the base. The replaceable die core includes an upper surface, and the replaceable die core defines a chamber depressed downwardly at a center of the upper surface. A bottom portion of the optical lens is formed by in the chamber. The replaceable die core defines a plurality of fixing holes recessed downwardly from the chamber for forming positioning feet of the optical lens.
