Resin lens injection mold

Abstract

The invention relates to the technical field of injection molds, and in particular, relates to a resin lens injection mold which comprises a fixed mold body and a movable mold body; the fixed mold body is fixedly mounted on an upper mold frame and provided with a convex part used for resin lens forming, and the movable mold body is fixedly mounted on a lower mold frame and provided with a concave part used for resin lens forming; a gap between the concave part and the convex part forms a mold cavity matched with the shape of the resin lens, and the mold cavity comprises a plurality of first injection molding cavities and a plurality of second injection molding cavities; and the plurality of first injection molding cavities are provided, the number of the second injection molding cavities is the same as that of the first injection molding cavities, the second injection molding cavities are matched with the shape of the resin lens, the upper mold frame is provided with a first cooling cavity, a first cooling mechanism is arranged in the first cooling cavity, the lower mold frame is provided with a second cooling cavity, and a second cooling mechanism is arranged in the second cooling cavity. Through mutual cooperation of the first cooling mechanism and the second cooling mechanism, bidirectional cooling is achieved in advance, and the injection molding cooling demolding efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to a resin lens injection mold. Background technique [0002] Injection mold is a tool for producing plastic products; it is also a tool for giving plastic products complete structure and precise dimensions. Injection molding, also known as injection molding, is a molding method of injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, automatic operation, various designs and colors, simple to complex shapes, large to small sizes, accurate product sizes, easy replacement of products, and complex shapes. Parts, injection molding is suitable for mass production and complex shape products and other molding processing fields. [0003] When the injection mold is being injected, it needs to be cooled and demolded in the later stage. However, during the cooling and demoulding process of special-shaped products, the coolin...

AI Technical Summary

Problems solved by technology

[0004] Based on this, it is necessary to address the problems of the prior art and provide a resin lens injection mold, which passes through the first cooling mechanism in the first cooling cavity of the upper mold base and the second cooling mechanism in the second cooling cavity of the lower mold base. At the same time, the mechanism cools the unseparated movable mold and fixed mold for one end of time in advance, so that the resin lens in the mold cavity is uniformly cooled. After cooling for one end of time, the upper mold frame and the movable mold rise, and then pass through the The second cooling mechanism cools the bottom of the resin lens in the second injection cavity, so as to better cool the resin lens and demould, which solves the problem of poor local heat dissipation during injection molding of the resin lens, which will eventually lead to insufficient demoulding effect , technical issues affecting product quality
