Embodiment 1
[0022] In this embodiment, as attached Figure 1~4 As shown, the sawtooth insert 1 includes a sawtooth part 11, a fixed slope 12 and a fixed protrusion 13. The sawtooth part 11 is provided with a plurality of sawtooth forming grooves, and its end is a sharp inverted mold structure. The fixed protrusion 13 Set on the edge of the sawtooth insert 1, the fixed slope 12 is arranged on the inner side of the fixed slope 12, the bottom end of the fixed slope 12 is on the plane where the sawtooth part 11 is located, and the protective insert 2 is provided with a joint part 21, locking The inclined surface 22 and the locking portion 23, the locking portion 23 is specifically a right-angled structure, and one end of the locking inclined surface 22 is connected to one end of the locking portion 23, and the other end is connected to one end of the joint portion 21, and the joint portion 21 is arranged on the protective cover. One side of insert 2. The protection part is specifically a smo...

The invention discloses a forming mold for light-in sawteeth of a light guide plate. The forming mold comprises a sawtooth insert and a protective insert, wherein the sawtooth insert comprises a fixing bulge and a sawtooth part, the sawtooth part is arranged on the upper surface of the sawtooth insert, the fixing bulge is arranged at the edge of the sawtooth insert, the protection insert comprisesa combination portion and a clamping portion, the combining portion is arranged on the upper surface of the protective insert, the clamping portion is arranged on one side of the combining portion, the protective insert is arranged on the sawtooth insert, the combining portion is arranged on the sawtooth part, and the clamping portion and the fixing bulge are mutually clamped. The protective insert is additionally arranged, and the structure of the sawtooth insert is modified, so that not only can the sawtooth mold on the mold be protected after the protective insert and the sawtooth mold arecombined, but also the problems of the overflow edge and the non-uniform stress deformation after combination can be solved.
Description
technical field [0001] The invention relates to the field of design mold processing, in particular to a structural mold for forming a light guide plate. Background technique [0002] In the current processing process of backlight light guide plate, because the structure of the light guide plate itself is relatively complex, and the structure changes between different requirements, it is generally produced in the form of a combined mold. The combined mold will need to produce different parts of the light guide plate. The structure is divided into multiple moulds, which are combined and then injection molded at one time during the overall production, so the production is simple. When it is necessary to modify the parameters of a certain part of the light guide plate, the mold of the part that needs to be modified can be directly taken out, processed or replaced, which greatly solves the problem of production cost. [0003] In the process of light guide plate production, the p...
