Optical lens mold casting system

Abstract

The invention discloses an optical lens mold casting system. The system comprises a bottom plate I fixed at the top end of a base, and a supporting plate is fixedly connected to the top end of the bottom plate I. According to the system, through the arrangement of an infusion pump II, stretching-out and drawing-back of a hydraulic rod is combined, a liquid outlet on a round rod is utilized, a liquid raw material at a temperature is poured into a molding cavity between an upper mold and a lower mold, the hydraulic rod is used to generate downward pressure on the upper mold, the tightness and the fitting degree between the upper mold and the lower mold are improved, so that the upper mold and the lower mold are not prone to deflection, after the raw material is poured, the hydraulic rod cancontract so that the side wall of the bottom end of the round rod and the side wall of the top end of the upper mold can form a whole, the wrinkling rate of the surface of an optical lens is reduced,a cooling device is adopted to cool the optical lens, so that the optical lens can be easily separated from the mold, a worker can conveniently take out the optical lens, the whole structure is simple, the mechanization degree is high, and the operation is very convenient.

Description

technical field [0001] The invention relates to the technical field of optical lens manufacturing, in particular to an optical lens mold pouring system. Background technique [0002] At present, most of the optical lenses we see in our daily life are mainly made of resin or glass materials. Among them, optical lenses made of resin materials are favored by consumers because of their light weight, not easy to break, and strong anti-fog properties. Regardless of whether resin materials or glass materials are used to manufacture optical lenses, three major processing procedures must be carried out: substrate molding, hardening treatment, and coating packaging. [0003] Among them, substrate molding is the first and most critical production link. The main process is to introduce the pre-prepared liquid raw materials into the optical lens mold by manual injection, and then pour them into the optical lens mold. Sealed, extruded, ejected after cooling, and then enters the next step...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the shortcomings in the prior art, such as: the existing optical lens mold sealing is not high, and at the same time after the compression molding of the optical lens is completed, because the liquid raw material itself has a certain temperature, its It is easy to bond with the inner wall of the mold. If the ordinary ejection mechanism is used to eject it directly, it is easy to cause cracks on the surface of the optical lens and increase the defective rate of the product.
