Mold core for manufacturing light guide plate and microstructural manufacturing method of mold core

Abstract

A microstructural manufacturing method of a mold core comprises the following steps that an aligned insert is mounted on a mold core body; then the aligned insert and the mold core body are subjectedto mirror polishing, so that a datum plane is formed by the aligned insert, and a polished face is formed by the mold core body, wherein the datum plane and the polished face are cut flush; after thealigned insert and the mold core body are subjected to mirror polishing, the aligned insert and the mold core body are separated; then the aligned insert and a processed insert are fixed to the horizontal plane, wherein the bottom face of the aligned insert and the bottom face of the processed insert are both located on the horizontal plane; then the processed insert is planed to form a smooth face, wherein the height of the smooth face relative to the horizontal plane is substantially equal to the height of the datum plane relative to the horizontal plane; and then the processed insert is cutfrom the smooth face to form a microstructural insert. In addition, the mold core is provided.

Description

technical field [0001] The present invention relates to a tool for manufacturing a light guide plate and a method for manufacturing a light guide plate, and in particular to a mold core for manufacturing a light guide plate and its microstructure. method. Background technique [0002] A light guide plate is an existing common optical element, which can be used as a surface light source capable of emitting light uniformly, and the existing light guide plate is usually used in liquid crystal displays and lamps. There are usually microstructures on the surface of the light guide plate, which can scatter light, so that the light transmitted in the light guide plate can exit from the light-emitting surface of the light guide plate. The current light guide plate has been made by mold core, and the microstructure can also be formed by mold core. The above-mentioned microstructure can influence the optical performance of the light guide plate, so the mold core used to manufacture ...

AI Technical Summary

Problems solved by technology

However, when designing the local microstructure of the mold core, the entire mold core needs to be nickel-plated before processing. The large-area nickel layer is easily damaged during production, and maintenance needs to be completely reprocessed, which consumes more production costs and man-hours.
