Abstract

The utility model discloses a liquid crystal display frame panel formed by double-layer compound injection molding. The liquid crystal display frame panel is made of two different plastic materials by adopting an inner layer and a surface layer which are formed by integrated injection molding, wherein the inner layer is completely wrapped by the transparent surface layer. The surface layer of the liquid crystal display frame panel formed by double-layer compound injection molding can be made of transparent friction-resistant plastics with excellent surface fineness such as PMMA and the like, and the inner layer is made of high-strength plastics such as ABS, HRPS and the like, so that the liquid crystal display frame panel not only solves the problem of the strength of a frame panel, but also solves the problem of appearance quality of the frame panel, and simultaneously reduces product cost.

Description

The LCD frame panel of two-layer compound injection mo(u)lding

Technical field:

The utility model relates to a kind of LCD frame panel, relates in particular to a kind of LCD frame panel of two-layer compound injection mo(u)lding.

Background technology:

Framework face frame is the main member that is used for installing LCDs in the LCD.During assembling, earlier LCDs is fixed on the framework face frame, and then framework face frame is fixed on the front port place of casing.

Along with the progress of expanding economy and society, LCD is maximized people and aesthetic property has had higher requirement, at this requirement, just seem particularly important as the intensity and the presentation quality of the critical piece in the display-display frames face frame.

Present display frames face frame substantially all adopts same injection molding, and this class display framework face frame exists following problem:

1), in order to increase the intensity of display frames face frame, sometimes need in plastics, increase auxiliary agent, but increasing auxiliary agent makes material flowability poor, be difficult to guarantee the surface smoothness of framework face frame, thereby have influence on the presentation quality of product, sometimes just need framework face frame table face to carry out spray treatment, thereby increased the production cycle of product, also polluted environment the same period.Reduce the increase of amount of auxiliary if only consider the outward appearance of product, can sacrifice the intensity of framework face frame again.

2), adopt the framework face frame of unitary plastic injection mo(u)lding, for other part of display is installed, as button, loudspeaker, pilot lamp, need on display frames face frame, offer some holes and some supports are set, and the presentation quality that these holes and support will certainly have influence on display frames face frame is set.

3) if should guarantee the intensity of framework face frame, guarantee its presentation quality again, sometimes adopt the better plastics of performance to carry out injection moulding, increased cost of products so again with regard to needs.

The utility model content:

Technical problem to be solved in the utility model is to provide at the deficiencies in the prior art a kind of LCD frame panel of two-layer compound injection mo(u)lding, this framework face frame can guarantee the intensity of framework face frame, presentation quality can be guaranteed again, the cost of product can also be reduced simultaneously.

To achieve these goals, the technical solution of the utility model is as follows:

The LCD frame panel of two-layer compound injection mo(u)lding, this liquid crystal display panel adopts the internal layer and the surface layer of subtend injection integrated injection molding to constitute by two kinds of different plastic materials, and described surface layer coats internal layer fully, and wherein surface layer is a transparent surface layer.

The middle part, bottom of described internal layer is provided with the breach that is used to install display unit.

Be provided with the leg that several are used to install LCDs around the described surface layer inboard.

Owing to adopt technique scheme, the LCD frame panel of two-layer compound injection mo(u)lding of the present utility model, its surface layer can adopt the plastics that PC, PMMA etc. are transparent and surface smoothness is good, internal layer employing ABS, the plastics that the HRPS equal strength is high, promptly solved the strength problem of framework face frame, solve the appearance quality of framework face frame again, reduced cost of products simultaneously.

Description of drawings:

Further specify the utility model below in conjunction with the drawings and specific embodiments.

Fig. 1 is the utility model structural representation.

Fig. 2 is an A-A view among Fig. 1.

Embodiment:

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

As depicted in figs. 1 and 2: the LCD frame panel of two-layer compound injection mo(u)lding, this liquid crystal display panel adopts the internal layer 100 and the surface layer 200 of integrated injection molding to constitute by two kinds of different plastic materials, surface layer 200 materials are PC or PMMA, and internal layer 100 adopts ABS.Surface layer 200 coats internal layer 100 fully, and surface layer 200 is a transparent surface layer, is provided with the breach 110 that is used to install display unit in the middle part, bottom of internal layer 200, is provided with the leg 210 that several are used to install LCDs around surface layer 200 inboards.

The LCD frame panel of the utility model two-layer compound injection mo(u)lding adopts Mitsubishi's Large Electric two material compound rotating injection molding machines, its Shooting Technique is leading domestic technology, what adopt is the method for rotation, combined shaping in subtend injection molding unit, the mould machine, this injection molding machine is based on electric injection machine forming machine 1450emR series, append counter-rotating template and 2 adapted to injection system, realize that two material compound rotating electric injection machines are shaped.This injection molding machine has following feature:

1), the configuration of the subtend of injection device, give mould and design great degree of freedom;

2), in counter-rotating with on the template equipment, realize the chilled water that each is serial, the Multi Loading and Unloading Functions of electric and oil hydraulic circuit;

3), can change system by corresponding laterally automatic die;

4), motorized operation, reach the remarkable environmental energy-saving effect thereby adopt the electric power technology of bringing back to life effectively to economize on electricity.

The injection molding machine of the utility model employing in processing is handled also has two material composite moldings in addition, reduces the spraying assembling procedure, and rationally materials used is realized the advantage that two kinds of resins are fitted.

More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
