Abstract
The utility model relates to the technical field of ultrathin light guide plates and especially relates to a flow channel of an ultrathin light guide plate mould. The flow channel of an ultrathin light guide plate mould comprises a flow channel body, wherein mould glue openings are arranged on the two ends of the flow channel body, and the length of the flow channel body is 60-80mm. The length of the flow channel body is 70mm. The mould glue opening is a mould glue opening with a trapezoidal cross section, one side with small aperture of the mould glue opening is communicated with the flow channel body, and the side with large aperture of the mould glue opening is communicated with a mould die cavity. A vertical plate vertical to the mould die cavity is arranged on the large aperture side of the aperture of the mould glue opening communicated with the mould die cavity. The flow channel of an ultrathin light guide plate mould disclosed by the utility model guarantees small pressure for the molten plastic liquid flowing into the mould die cavity and good uniformity of the manufactured ultrathin light guide plates, and the structure of the flow channel is simple.
Description
Technical field
The utility model relates to the ultra-thin light guide board technical field, especially a kind of runner of ultra-thin light guide board mould.
Background technology
Runner refers to the path that fluid flows in the hydraulic system in element.Common flow passage system is also referred to as runner system or running gate system, be molten plastic from the ejaculator nozzle to die cavity must channel.Flow passage system comprises sprue, runner and cast gate.
Consult Fig. 1, in the injection molding technology of ultra-thin light guide board, adopt the following linear pattern runner charging of size 50 mm so that the pressure of the interior molten plastic liquid of mold cavity is larger, because the material of mfg. moulding die is not absolute rigid material, in the large situation of pressure, can produce certain deformation, the pressure that is plastic liquid struts mold cavity, make the desired shape of mold cavity and product that difference slightly be arranged, for common LGP, impact is not very large, but slight difference is just very obvious for ultra-thin light guide board, even causes product undesirable.
Summary of the invention
The utility model has overcome shortcoming of the prior art, and the runner of ultra-thin light guide board mould is provided, and mold cavity can not strutted by the pressure of plastic liquid, the ultra-thin light guide board high conformity of manufacturing.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The runner of ultra-thin light guide board mould comprises the runner body, and described runner body two ends are provided with the mold glue mouth, and described runner body length is 60 to 80mm.
Further, described runner body length is 70 mm.
Further, described mold glue mouth is that to have cross section be trapezoidal mold glue mouth, and the small-bore side of described mold glue mouth is communicated with described runner body, and the bigbore side of described mold glue mouth is connected with mold cavity.
Further, the bigbore side of described mold glue mouth that is connected with described mold cavity is provided with the riser perpendicular to mold cavity.
Compared with prior art, the beneficial effects of the utility model are:
The long pressure that flows into the molten plastic liquid in the mold cavity that makes of the runner of the utility model ultra-thin light guide board mould is less, the ultra-thin light guide board high conformity of manufacturing, and also simple in structure.
Description of drawings
Accompanying drawing is used to provide further understanding of the present utility model, is used from explanation the utility model with embodiment one of the present utility model, does not consist of to restriction of the present utility model, in the accompanying drawings:
Fig. 1 is the flow passage structure schematic diagram of prior art products mould;
Fig. 2 is the flow passage structure schematic diagram of the utility model ultra-thin light guide board mould.
Wherein, 1---the runner body;
2---the mold glue mouth;
3---mold cavity;
4---riser.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in restriction the utility model.
As shown in Figure 2, the runner of ultra-thin light guide board mould described in the utility model comprises runner body 1, and runner body 1 two ends are provided with mold glue mouth 2, and runner body 1 length is 70 mm.Traditional runner body 1 length is 50mm, and runner body 1 of the present utility model is longer than traditional runner body 1, and the pressure that therefore flows into the molten plastic liquid in the mold cavity 3 is less, the ultra-thin light guide board high conformity of manufacturing.
Mold glue mouth 2 is trapezoidal mold glue mouth 2 for having cross section, and mold glue mouth 2 small-bore sides are communicated with runner body 1, and mold glue mouth 2 bigbore sides are connected with mold cavity 3.Mold glue mouth 2 bigbore sides that are connected with mold cavity 3 are provided with the riser 4 perpendicular to mold cavity.
LGP Jiao Kou is cropped neat, good product consistency, and no longer need subsequent handling manually again to process can to reach requirement, improve production efficiency, save human cost.
It should be noted that at last: above only is preferred embodiment of the present utility model; be not limited to the utility model; although with reference to embodiment the utility model is had been described in detail; for a person skilled in the art; it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing; perhaps part technical characterictic wherein is equal to replacement; but all within spirit of the present utility model and principle; any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
