Problems solved by technology

At present, companies using this technology cannot effectively remove it: either the removal is not clean; or scars or marks will be formed on the surface of the mold
Plastic products (commonly known as light guide plates) produced by using molds with metal attachments and uneven surfaces on the surface are prone to air marks and poor fluidity in injection molding; use this optical mold to assemble backlight products and display screens, It is also easy to cause yellowing of the display, uneven luminescence, and low brightness

Embodiment Construction

[0017] In order to better understand the technical solution of the present invention, the following describes the embodiments provided by the present invention in detail.

[0018] The embodiment of the present invention provides a high-pressure process for removing metal attachments and surface unevenness after microstructure processing on the surface of an optical mold. A cleaning medium, such as air, liquid (water, etc.) is added through high-pressure equipment (high-pressure air guns, high-pressure water guns, etc.) , oil or other rust-removing liquid cleaning agents, etc.), high-pressure washing the microstructure surface of the optical (display backlight) mold processed by precision laser equipment, to achieve the clean, smooth and smooth effect of the microstructure surface of the mold. Specific steps:

[0019] Step 1: Fix the mold with processed microstructure by sucking it with a magnetic disk or clamping it with a vise.

[0020] The second step: cleaning the microstr...

Abstract

The invention provides a technology for removing metal attachments and surface unevenness of a processed surface micro-structure of an optical mould under high pressure. The technology comprises the following steps of: 1, fixing a mould with a micro-structure processed in the third step by sucking through a magnetic disk or clamping through a bench clamp; 2, cleaning the surface of the micro-structure of the processed mould; 3, detaching the cleaned mould from the magnetic disk or bench clamp; and 4, checking the surface of the micro-structure of the cleaned mould. The production yield of plastic products (namely, light guide plates) is increased; the production difficulty is reduced; and the light equalization, color equalization and luminance of the light surfaces of screen backlight products and display screen end products are promoted.

Description

technical field [0001] The invention relates to the technical field of optical equipment, in particular to a process for removing metal attachments and surface unevenness after microstructure processing on the surface of an optical mold under high pressure. Background technique [0002] The surface of the optical mold will form metal deposits and surface unevenness. At present, companies using this technology cannot effectively remove it: either the removal is not clean; or scars or marks will be formed on the surface of the mold. Plastic products (commonly known as light guide plates) produced by using molds with metal attachments and uneven surfaces on the surface are prone to air marks and poor fluidity in injection molding; use this optical mold to assemble backlight products and display screens, It is also easy to cause yellowing of the display, uneven luminescence, and low brightness. Contents of the invention [0003] The invention provides a high-pressure process...
