Abstract
The invention discloses a production mould for the rear cover of a notebook computer display, comprising an interior bulge located at the middle of a product, as well as an exhaust port and an air channel arranged at the interior bulge, wherein the exhaust port is communicated with the air inlet of the air channel, and the air outlet of the air channel is communicated with air. According to the production mould for the rear cover of a notebook computer display provided by the invention, the exhaust system of the mould is simplified and the exhaust quality during production is improved via the design of the air channel.
Description
Technical field
The present invention relates to the production mould of notebook display outside framework, relate in particular to a kind of production mould of notebook display bonnet.
Background technology
Frame and bonnet two parts before the outside framework of notebook display comprises, and be mostly the moulding profiled member.Through preceding frame and bonnet two parts with display screen fixing after, bonnet covers the whole back side that covers display, preceding frame covers the front avris that covers display, and exposes the display surface of display; Can find out that by this structure preceding frame is the less square frame spare of width, and bonnet relatively before frame be face type spare, so before design during the mould of frame and bonnet, all should be different to the design of liftout attachment, running channel, rising head.
The production mould of the outside framework of notebook display mainly comprises upper die and lower die and liftout attachment, and liftout attachment at first resets during production, and the matched moulds upper die and lower die inject melted material in the die cavity that behind matched moulds, forms again then; Remove patrix after the injection mo(u)lding, through liftout attachment eject the stake product after the moulding is ejected in the die cavity of counterdie, can carry out following process to the product after the moulding.
Existing upper die and lower die all adopt independently channel design when the design gas extraction system; Need the place of exhaust to design an exhaust outlet at die cavity exactly specifically; And directly derive gas through an exhaust passage; Do not have contact between each exhaust outlet, this is no problem during frame before production.But bonnet is a face type spare; The structure of bonnet 1 die cavity as shown in Figure 1; There are some slightly parts (dash area among the figure, promptly internal protrusion 2) of microprotrusion in its inboard meeting, and the height of these internal protrusion 2 is not very high; But when moulding but being the part that is filled at last, also is the critical positions of our designing and arranging gas port therefore; Existing mould design to this bonnet is as shown in Figure 2, near internal protrusion 2, designs water route 3, accelerates the cooling of melted material, and exhaust outlet is independent design and through corresponding exhaust passage gas everywhere at the needs place; For the internal protrusion that is positioned at avris 2; It is very convenient that directly the designing and arranging gas port is derived gas outside mould; But for the internal protrusion that is positioned at the centre 2; If the designing and arranging gas port will make the production and processing of mould very difficult with corresponding exhaust passage exhaust respectively, and is difficult to guarantee exhaust quality.
Summary of the invention
Goal of the invention: in order to overcome the deficiency that exists in the prior art, the present invention provides a kind of production mould of notebook display bonnet, and the design gas circuit is communicated with the exhaust outlet at the internal protrusion place of central part, simplifies the die venting system architecture.
Technical scheme: for solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
The production mould of notebook display bonnet comprises the internal protrusion, the exhaust outlet that is arranged on the internal protrusion place, the gas circuit that are positioned at the product middle part, and said exhaust outlet is communicated with the air inlet of gas circuit, the gas outlet of said gas circuit and air communication.
Said structure; Need be according to the trend of the position appropriate design gas circuit of exhaust outlet; Must discharge by limited gas outlet through gas circuit from the gas that exhaust outlet is discharged; Reduced the exhaust passage of corresponding exhaust outlet design difficulty, reduced the Mould design difficulty, the exhaust quality when producing can also be provided simultaneously.
Preferably, said gas circuit is arranged on the outside of internal protrusion and the gap location between the internal protrusion.
Preferably, the spacing of said gas circuit and internal protrusion is preferably between 6 ~ 10mm greater than 5mm.
Preferably, the aperture of said gas circuit preferably can be less than 1mm less than 2mm.
Preferably, said gas circuit is one, also can be two or three, but too much unsuitable, otherwise just loses the meaning of gas circuit.
Beneficial effect: the production mould of notebook display bonnet provided by the invention, through the gas circuit design, simplified the gas extraction system of mould, improved the exhaust quality when producing.
Description of drawings
Fig. 1 is the structural representation of bonnet die cavity;
Fig. 2 is existing mould structure sketch map;
Fig. 3 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done explanation further.
Be illustrated in figure 3 as the production mould of notebook display bonnet; Comprise internal protrusion 2, the exhaust outlet that is arranged on internal protrusion 2 places, a gas circuit 3 of being positioned at the product middle part; Said gas circuit 3 is arranged on the outside of internal protrusion 2 and the gap location between the internal protrusion 2; And the spacing of gas circuit 3 and internal protrusion 2 is greater than 5mm, and the aperture of gas circuit 3 is less than 2mm; Said exhaust outlet is communicated with the air inlet of gas circuit 3, the gas outlet of said gas circuit 3 and air communication.
The above only is a preferred implementation of the present invention; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
