Problems solved by technology

[0003] In addition, the manufacture of light guide plates often uses precision mold cores for injection molding. When processing mold cores, due to the processing of microstructures with gradual angles, mold cores often have burrs. Due to the special mold cores In the past, if the model was injured, it could only be scrapped and remade, which is more wasteful

Embodiment Construction

[0033] see Figure 1~5 , in an embodiment of the present invention, a mold core processing device for manufacturing a light guide plate with a gradual angle, which includes a machine body 1, an oscillating uniform liquid component 2, a processing table 3, a mold core 4, and a burr repair component 5, wherein , the oscillating uniform liquid component 2 is arranged in the body 1, and the oscillating end of the oscillating liquid uniform component 2 is connected to a processing table 3, and a mold core 4 is fixed on the processing table 3, and the mold core 4 The burr repair assembly 5 is arranged above;

[0034] The burr repair component 5 can sequentially provide coating, sandblasting and polishing for the mold core;

[0035] Wherein, when the burr repairing component 5 sprays liquid and coats the mold core, the oscillating uniform liquid component 2 can drive the mold core 4 to vibrate at the same time, so that the coating liquid does not adhere to the burrs higher than the ...

Abstract

The invention discloses a mold core processing device for manufacturing a light guide plate with a gradual angle, which relates to the technical field of light guide plate mold core manufacturing, and includes a machine body, an oscillating uniform liquid component, a processing table, a mold core and a burr repair component , wherein, the oscillating uniform liquid component is arranged in the body, and the oscillating end of the oscillating liquid uniform component is connected to a processing table, a mold core is fixed on the processing table, and a mold core is arranged above the mold core. The burr repairing assembly; the burr repairing assembly can provide coating, sandblasting and polishing for the mold core in turn; wherein, when the burr repairing component sprays liquid coating on the mold core, the oscillating uniform liquid component can simultaneously drive The mold core is oscillated so that the coating liquid does not adhere to the burr higher than the molding surface of the mold core, so that the subsequent sandblasting treatment is possible.

Description

technical field [0001] The invention relates to the technical field of mold core manufacturing for light guide plates, in particular to a mold core processing device for manufacturing light guide plates with gradual angles. Background technique [0002] Known backlight modules can be mainly divided into direct-type and side-type backlight modules. The current common backlight module structure is mainly based on single-side light input, so it is easy to reach the two sides of the backlight module due to the relatively small amount of light. less, but lower than the central luminance, and there is a certain gap between the side luminance and the central luminance. When using a high-directivity structure, it can improve the forward light-emitting efficiency and increase the overall luminance. However, due to its Due to the convergence of the emitted light, the luminance difference between the side and the center will increase, which will intensify the contrast between light and...
