Embodiment Construction

[0037] The following is attached Figure 1-5 The application is described in further detail.

[0038] The embodiment of the present application discloses a mold for forming a light guide plate in which a male mold, a rubber mouth, and a core are integrated. refer to figure 1 and figure 2 ,, the light guide plate molding mold with integrated male mold, rubber mouth and core includes an upper mold assembly and a lower mold assembly, wherein the upper mold assembly includes an upper mold base 1 and a shaping block 2, and the bottom of the upper mold base 1 is provided with a shaping Groove 3 and shaping block 2 are fixedly installed in shaping groove 3 through two rows of countersunk head bolts. The thickness is slightly greater than the depth of the groove of the shaping groove 3, that is, the bottom of the shaping block 2 passes outside the shaping groove 3.

[0039] refer to figure 2 , in order to further enhance the stability of the position of the shaping block 2, the...

Abstract

This application relates to the technical field of light guide plate production, in particular to a light guide plate forming mold with integrated male mold, rubber mouth and mold core, which includes a mounting plate, a mounting groove is opened on the top of the mounting plate, and a molding block is installed in the mounting groove , the top of the forming block is sequentially recessed with a forming part, a rubber mouth part, a runner part and a main channel part along the horizontal direction, and the forming part is adapted to the shape of the light guide plate. The application has the effect of making the light guide plate less likely to produce foreign matter due to gaps during injection molding, thereby improving the production yield.

Description

technical field [0001] The present application relates to the field of light guide plate production, in particular to a light guide plate forming mold integrating a male mold, a rubber mouth, and a core. Background technique [0002] The light guide plate is a kind of plate commonly used in the backlight module of LCD display screen and notebook computer. The light guide plate is usually formed by injection molding in the production. During the forming process of the light guide plate, the molten forming material needs to be filled into the closed area by high pressure. inside the mold. [0003] In the related art, the injection mold used for the production of the light guide plate usually includes a rear mold core part and a rubber mouth part that are fitted together. The final molding is in the rear core part. [0004] In view of the above-mentioned related technologies, the inventor believes that there is a small gap between the rear mold core part and the rubber mouth ...
