A mold core processing device capable of reducing adsorption and scratching of light guide plates

Abstract

The invention discloses a mold core processing device capable of reducing adsorption and scratches of a light guide plate, which includes a support base, an external casing, a stamping cylinder, an upper forming die assembly, a lower forming die assembly, and a transmission device. The external machine The shell is connected and fixed with the support base by fixing bolts, the lower molding die assembly is installed in the middle of the upper end surface of the support base, and a transmission device is arranged in the accommodation chamber of the support base, and the transmission device is connected with the lower mold assembly. The forming die assembly is fixed so that the lower forming die assembly can be relatively rotatably fixed on the support platform, and a stamping cylinder is vertically fixed inside the upper end surface of the outer casing, and the output end of the stamping cylinder It is connected and fixed with the upper forming die assembly, and drives the upper forming die assembly to slide up and down; the upper forming die assembly is located directly above the lower forming die assembly, and cooperates with the lower forming die assembly The mold core of the light guide plate is stamped and formed.

Description

technical field [0001] The invention relates to the technical field of mold core processing equipment for a light guide plate, in particular to a mold core processing device capable of reducing adsorption and scratches on a light guide plate. Background technique [0002] Liquid crystal display is currently a common display product, and the liquid crystal display itself does not emit light, so it needs a backlight module as a backlight source. The common components of a backlight module are light source, reflector, light guide plate, diffusion sheet, prism sheet, etc. However, the light guide plate in the backlight module often absorbs with the reflector because the depth of the lower surface structure is too flat, resulting in white spots on the screen. Among them, the main structure of the mold core of the light guide plate directly affects the light guide plate. Light guiding performance. However, in the prior art, for the preparation of the mold core of the light guide ...

[0002] Liquid crystal display is currently a common display product, and the liquid crystal display itself does not emit light, so it needs a backlight module as a backlight source. The common components of a backlight module are light source, reflector, light guide plate, diffusion sheet, prism sheet, etc. However, the light guide plate in the backlight module often absorbs with the reflector because the depth of the lower surface structure is too flat, resulting in white spots on the screen. Among them, the main structure of the mold core of the light guide plate directly affects the light guide plate. Light guiding performance

However, in the prior art, for the preparation of the mold core of the light guide plate, the mold core of the light guide plate made by two-way machining is usually processed longitudinally with an R-angle cutter, and the top of the R angle is often too flat to effectively reduce the adsorption phenomenon. In order to eliminate the white spots and scratches caused by adsorption, it is necessary to reduce the contact area between the core structure of the light guide plate and the light guide plate. Processing, the processing difficulty coefficient is high, the processing procedure in manual cutting processing is relatively cumbersome, and the precision is low
