Glass light guide plate injection mold and light guide plate injection molding process

Abstract

The invention discloses a glass light guide plate injection mold and a light guide plate injection molding process. The glass light guide plate injection mold comprises a male mold holder and a femalemold holder which are used in cooperation. The female mold holder comprises a panel, a stripper plate, a female mold plate and a female mold core. The male mold holder comprises a bottom plate, moldlegs, a male mold plate and a male mold core. A light guide plate cavity is formed between the female mold core and the male mold core. The male mold holder is internally provided with a male mold cooling water runner. The female mold holder is internally provided with a female mold cooling water runner. A positioning structure used for relative sliding of the male mold holder and the female moldholder is included. The positioning structure further comprises positioning sleeves fixedly connected with the periphery of the male mold plate and positioning rods fixedly connected with the female mold plate, and further comprises positioning convex blocks located on the side wall of the male mold plate and positioning grooves located in the side wall of the female mold plate. According to the mold, positioning stability of the male mold holder and the female mold holder can be improved through matched sleeving connection of the positioning sleeves and the positioning rods and matched clamping connection of the positioning convex blocks and the positioning grooves.

Description

technical field [0001] The invention belongs to the technical field of moulds, in particular to an injection mold for a glass light guide plate. Background technique [0002] With the continuous improvement of people's living standards, plastic products have become an indispensable synthetic material in modern life. Plastic has the advantages of light weight, stable chemical properties, excellent electrical insulation properties, good noise reduction and shock absorption, high specific strength, and wide distribution of mechanical strength. Injection molding technology is to add granular or powdery polymer raw materials into the polymer barrel, plasticize under heating or mechanical shearing, and finally enter the mold under the push of a plunger or screw, and cool and solidify to form a mold cavity. Consistent polymer articles. Injection molding technology is one of the main processing methods of plastic products and can produce and manufacture complex molded products at ...

AI Technical Summary

Problems solved by technology

[0003] With the continuous development of the plastics industry, the mechanical properties and dimensional accuracy of products are increasingly required in plastic products. The existing injection molds often cause air pockets, weld lines, and even warping in the finished product due to unreasonable design. Deformation and other defects, resulting in low production efficiency and low product qualification rate, and the unreasonable design of the mold will also shorten the service life of the mold
