Abstract

The utility model discloses a die for light guide plate production. The die comprises a glass upper die and a glass lower die, wherein the glass upper die and the glass lower die are made of glass; a cavity used for accommodating a pouring liquid and molding a light guide plate is arranged in the glass lower die; the shape of the cavity is matched with that of the formed light guide plate; a plurality of formed small recesses or lug bosses used for molding optical structural points on the surface of the light guide plate are arranged on the bottom surface of the cavity; a plurality of formed small recesses or lug bosses used for molding optical structural points on the surface of the light guide plate are arranged on the bottom surface of the glass upper die. According to the utility model, the light guide plate meeting the requirements can be produced through forming at one time, so that the equipment cost and the production cost are reduced.

Description

A kind of mould of producing LGP
Technical field
The utility model relates to LGP technical field, especially relates to a kind of mould of producing LGP.
Background technology
In prior art, LGP is extruded continuously by screw extruder, the large plate of extrusion molding forms platelet unit through cutting, on platelet unit, carry out again radium-shine processing or hot pressing processing, in platelet unit, process various optics depressions or optics salient point, LGP needs multiple working procedure and various processing equipment, and production efficiency is low, production cost is higher, is therefore necessary to be improved.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of mould of producing LGP, and it is simple in structure, and equipment cost is low, and production efficiency is high, reduces the production cost of LGP.
To achieve these goals, the technical scheme that the utility model adopts is:
A kind of mould of producing LGP, comprise glass patrix and the glass counterdie by glass material, made, glass counterdie is provided with for holding potting syrup and molding the die cavity of LGP, the shape of the shape of die cavity and finished product LGP matches, in the bottom surface of die cavity, be provided with somely for molding the little depression of moulding or the lug boss of the optical texture point on LGP surface, the bottom surface of glass patrix is provided with some for molding the little depression of moulding or the lug boss of the optical texture point on LGP surface.
Further, in technical scheme, described mould also comprises fixture, and fixture is glass patrix and the glass counterdie after matched moulds fixedly.
Further, in technical scheme, described glass patrix is identical with the contour shape of finished product LGP with the contour shape of the cavity forming after glass counterdie matched moulds.
Further in technical scheme, the edge that the die cavity edges of described glass counterdie is provided with corresponding LGP cuts the edge control chamber of shape.
Further, in technical scheme, described glass patrix is provided with pressing portion, and after glass patrix and glass counterdie matched moulds, pressing portion is pressed in the die cavity of glass counterdie.
Further, in technical scheme, the pressing portion of described glass patrix protrudes from the bottom surface of glass patrix.
Adopt after said structure, the advantage that compared to the prior art the utility model had is: the utility model can be produced satisfactory LGP by one-shot forming technique, and core rod can be replaced, produce the LGP of different size and contour shape, as long as replace to the core rod with respective shapes, whole casting equipment, glass patrix and glass counterdie are general, and highly versatile reduces equipment cost and production cost.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of mould of the present utility model.
Fig. 2 is the structural representation after mould matched moulds of the present utility model.
Fig. 3 is the structural representation of glass counterdie of the present utility model.
Fig. 4 is the structural representation of the LGP that forms out of the utility model.
In figure: 1, glass patrix 2, glass counterdie 4, LGP 5, lug boss 7, die cavity 8, pressing portion.
The specific embodiment
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
Embodiment, see shown in Fig. 1 to Fig. 4: a kind of mould of producing LGP, comprise glass patrix 1 and the glass counterdie 2 by glass material, made, glass counterdie 2 is provided with for holding potting syrup and molding the die cavity 7 of LGP 4, the shape of the shape of die cavity 7 and finished product LGP 4 matches, in the bottom surface of die cavity 7, be provided with somely for molding the little depression of moulding or the lug boss of the optical texture point on LGP 4 surfaces, the bottom surface of glass patrix 1 is provided with some for molding the little depression of moulding or the lug boss of the optical texture point on LGP 4 surfaces.Glass patrix 1 is provided with pressing portion 8, and the pressing portion 8 of glass patrix 1 protrudes from the bottom surface of glass patrix 1.After glass patrix 1 and glass counterdie 2 matched moulds, pressing portion 8 is pressed in the die cavity 7 of glass counterdie 2.Glass patrix 1 is identical with the contour shape of finished product LGP 4 with the contour shape of the cavity forming after glass counterdie 2 matched moulds.The edge that die cavity 7 edges of glass counterdie 2 are provided with corresponding LGP 4 cuts the edge control chamber of shape.Mould also comprises fixture, and fixture is glass patrix 1 and the glass counterdie 2 after matched moulds fixedly.
Mould of the present utility model only has glass patrix 1 and glass counterdie 2, mould is simple, die cost is low, for the production of LGP 4, it adopts pouring technology to produce, castable is injected in the die cavity 7 of glass counterdie 2, make again glass patrix 1 and glass counterdie 2 matched moulds, the pressing portion 8 of glass patrix 1 is pressed in the die cavity 7 of glass counterdie 2, heating makes potting syrup polymerization reaction take place again, thereby LGP 4 is formed out, and mold 4 two surperficial optics depressions of LGP or optics salient point simultaneously.The utility model can be produced satisfactory LGP 4 by one-shot forming technique, and mould can replace, and produces the LGP 4 of different size and contour shape, reduces equipment cost and production cost.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
