Abstract
The invention discloses a production mould for a front frame of a notebook display, comprising a runner and a mould cavity, wherein the runner is of a double-channel structure and comprises a first runner and a second runner with the completely same structure, and discharging holes of the first runner and the second runner are connected to the mould cavity after being communicated. By using the production mould for the front frame of the notebook display, provided by the invention, the structure of the runner is changed, impact force towards two sides is acted on fused materials flowing into the mould cavity, the speed of filling the fused materials into the whole mould cavity is increased, and the product forming quality is improved.
Description
Technical field
The present invention relates to the production mould of notebook display outside framework, relate in particular to the production mould of the preceding frame of a kind of notebook display.
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, the structure of running channel is the single channel structure, and promptly each running channel all only has a charging aperture and a discharging opening that is communicated with die cavity, and only possesses a communication passage between charging aperture and the discharging opening.The running channel of this structure is no problem when producing bonnet; Because the die cavity space of bonnet is bigger; The melted material that gets into from running channel only need flow to this die cavity middle part than large space, and in flow process, spreads to avris, fills full whole die cavity promptly.And just there is the problem of Shanghai Communications University in the running channel of this structure during frame before production; Because the width of preceding frame is less; The melted material that gets into from running channel need separately flow to both sides, and in order to guarantee the uniformity that flows of material, must designing melted material, to flow to the impulse force of both sides identical as far as possible with flow; It is vertical with the length direction of corresponding preceding edge that such requirement can only design running channel down; Like this, can analyze and obtain melted material after getting into die cavity, be to fill completely whole die cavity with the mode that spreads to both sides; Owing to there is not the impulse force of direct guiding both sides, the speed that melted material is filled is slower, influences the formed product 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 the production mould of the preceding frame of a kind of notebook display, makes melted material in getting into die cavity, receive impulse force rapidly to two side flow through appropriate design running channel structure, improves filling speed.
Technical scheme: for solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
The production mould of frame comprises running channel and die cavity before the notebook display, and said running channel is a channel structure, comprises identical in structure first running channel and second running channel, and the discharging opening of said first running channel and second running channel is communicated with the back and inserts die cavity.
The running channel of said structure; Two strands of melted materials flow to discharging opening simultaneously after getting into first running channel and second running channel; Melted material from first running channel and the outflow of second running channel all can not be vertical with the length direction of corresponding preceding edge like this, certainly exists a mutual impulse force, forces two strands of melted materials separately to flow to both sides; Improve melted material and fill the speed of full die cavity, improve the quality of formed product.
As a kind of selectable structure, said first running channel and second running channel form V-shape, the charging aperture connection independently of one another of the charging aperture of first running channel and second running channel.
As the selectable structure of another kind, said first running channel and second running channel form the O font, and the charging aperture of the charging aperture of first running channel and second running channel is connected.
Preferably, said running channel is an arcuate structure.
Beneficial effect: the production mould of frame before the notebook display provided by the invention; Changed the structure of running channel; Make the melted material that flows in the die cavity receive impulse force, improved melted material and filled the speed that expires whole die cavity, improved the quality of formed product to both sides.
Description of drawings
Fig. 1 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 1 as the production mould of the preceding frame of a kind of notebook display; Comprise running channel and die cavity 3; Said running channel is twin-channel arcuate structure structure, comprises identical in structure first running channel 1 and second running channel 2, and the discharging opening of said first running channel 1 and second running channel 2 is communicated with the back and inserts die cavity; As shown in the figure, said first running channel 1 and second running channel 2 form V-shape, the charging aperture connection independently of one another of the charging aperture of first running channel 1 and second running channel 2.
Said first running channel 1 and second running channel 2 can also be designed to form the structure of O font, and the charging aperture of the charging aperture of such first running channel 1 and second running channel 2 is connected.
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.
