V-cut light guide plate forming method and V-cut light guide plate forming mold

Abstract

The invention discloses a V-cut light guide plate forming method and a V-cut light guide plate forming mold. The method comprises the steps that glue is injected to the mold through an injection molding machine, glue injected by a glue injector flows into glue inlet runners on the two sides of a glue inlet through the glue inlet, the glue enters a light guide plate forming cavity through a short side of the light guide plate forming cavity, the glue flows along a groove in the light guide plate forming cavity until glue in the light guide plate forming cavity and a reserved space is enough toform a light guide plate; finally, die assembly is carried out, the light guide plate forming cavity is filled with glue, and the light guide plate forming step is executed. According to the V-cut light guide plate forming method, at least one part of groove does not need to receive glue coming through transverse cutting type flowing, use of the transverse cutting type glue flowing manner is reduced, and the problems that in the prior art, all grooves have to receive cutting type flowing glue, glue flowing is not facilitated, and forming is difficult are solved.

Description

technical field [0001] The invention relates to the technical field of light guide plate forming, in particular to a V-cut light guide plate forming method and a V-cut light guide plate forming mold. Background technique [0002] In the prior art, the movable mold core in the V-cut light guide plate forming mold is to extend to both sides of the glue inlet to set up a glue inlet flow channel, which is respectively connected to a longitudinally arranged light guide plate molding through the glue inlet flow channels on both sides. Cavity, after glue injection, the glue enters the light guide plate molding cavity along the glue inlet channel, and then flows longitudinally along the groove (for forming V-cut structure) in the light guide plate molding cavity, while cutting the groove horizontally, such as figure 1 as shown, figure 1 The double-line arrow in the middle is the colloid flow direction, and the single-line arrow is the light-incoming direction of the light guide pla...

AI Technical Summary

Problems solved by technology

[0005] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a V-cut light guide plate forming method and a V-cut light guide plate forming mold, aiming at at least solving the problem that all grooves in the prior art must receive transverse cutting flow The coming colloids lead to the problem of difficult molding
