Die pressing facility and method for forming optical lenses

Abstract

The invention discloses a die pressing facility and method for forming optical lenses. In one implementing manner, the die pressing facility comprises a preheating module, a forming module and a cooling module, wherein the preheating module circularly receives and preheats a plurality of prefabricated pieces for forming the optical lenses; the forming module is provided with a single machining station and continuously receives the multiple preheated prefabricated pieces from the preheating module, and the multiple prefabricated pieces are formed into the optical lenses in the single machiningstation; and the cooling module circularly receives the optical lenses from the forming module and cools and outputs the optical lenses. By adoption of the scheme, single-station forming can be achieved only through usage of one formal die, and compared with the situation that traditionally, N formal dies are needed for N stations, the die cost can be obviously reduced, and the product manufacturing period can be greatly shortened.

Description

technical field [0001] The invention relates to the field of optics, in particular to the field of forming optical lenses, and more particularly to a molding device and method for forming optical lenses. Background technique [0002] With the rapid development of optical technology, the performance requirements of optical lenses are constantly improving, and the demand for glass aspheric lenses is increasing. However, the high manufacturing cost of glass aspheric surfaces has always been a bottleneck affecting their wide application. [0003] At present, the existing glass aspheric lenses at home and abroad are basically formed by precision hot molding and isothermal molding, that is, the mold and the prefabricated parts in the mold are molded together in the molding equipment. Refer below figure 1 with figure 2 Briefly introduce conventional molding equipment. [0004] figure 1 is a schematic diagram of a conventional compression apparatus, and figure 2 It is a plan...

AI Technical Summary

Problems solved by technology

[0008] This molding equipment and molding method have a long molding cycle, low production efficiency, a large number of molds, short life, and low utilization, which will eventually lead to an increase in the manufacturing cost of optical lenses (such as glass aspheric lenses)
