Because of ID design and structure space restriction, need colouredly to close the lid pad and mobile phone key be made of one, though two traditional plate silica gel moulds can be realized the silica gel product moulding of double-colored or polychrome, the inside that this kind method can't accurately be controlled different colours is the configuration shape as a result; In order not make coloured silica gel moulding overflow to the transparent silica gel place and influence the button light transmission.Common process can only separate the silica gel spare of different colours die sinking and moulding, with glue they is pasted into one through R+R technology again after the moulding; Too little because of closing lid pad size, and the quality of fit requirement is high, and not only cost is high to cause this technology, and yield is not high, is prone to during environmental test lose efficacy.Though conventional three plate silica gel moulds can accurately be controlled internal structure and prevent defectives such as silica gel overflow, silica gel that once can only a kind of color of moulding, the silica gel of the different colours of moulding simultaneously.
Summary of the invention
The present invention aims to provide a kind of polychrome silica gel forming process, reliability puzzlement and the low problem of production efficiency when improving present coloured silica gel beam and button and making a product.
The invention provides a kind of silica gel polychrome three template die moulding process for this reason; It separates the cope match-plate pattern feed zone; The silica gel pigment that is about to different colours is placed on the different feeds district; Then through different glue-feeders, the silica gel of different colours is injected in the mould simultaneously, make the silica gel one-shot forming of different colours.
This technology can be implemented according to following master operation: key support is put into lower bolster; The middle template of closing; The silica gel of different colours is put into corresponding feed zone; Cope match-plate pattern closes; The silica gel moulding; Product is taken out in die sinking.
This technology can be used to produce the coloured silica gel beam and the one-body molded product of button of mobile phone.
Can be through the feed zone barricade be set, neither can batch mixing when making moulding, can fuse the convenient stub bar that takes out after the moulding again.
The present invention will solve following technical problem:
1. owing to good flowability is arranged during the silica gel moulding, thus need solve because of overflow causes not homochromy silica gel batch mixing during moulding, and influence outward appearance and function;
Blowing district divider wall height be set with following difficult point:
A. too high like divider wall, stub bar can not be practiced and is integral after the moulding, need when playing material to take out piecewise, and the molding cycle that extended, cost raises;
B. too low like divider wall, the silica gel of different colours meeting batch mixing has a strong impact on product appearance and function during moulding.
3. many owing to silica gel mould cave number, and different colorant need be placed apart, as adopt conventional artificial the placement, then blowing is chronic, influences molding cycle;
Utilize above-mentioned technology can obtain following beneficial effect (is example with a mobile phone key)
1. reduced silica gel mould quantity, with the synthetic cover silica gel mould of the silica gel mould that needs separately die sinking originally;
2. owing to mould reduces, so the corresponding minimizing of moulding cost that corresponding product has;
3. remove common process mid point glue the coloured silica gel of difference has been pasted the processing procedure on button, promoted efficient, saved the manpower that a sticker closes processing procedure simultaneously;
4. promote the profile fineness of product, significantly improved the reliability of product simultaneously.
Description of drawings
Fig. 1 is dual-color silica gel shaped structures figure of the present invention;
Fig. 2 is a master operation block diagram of the present invention.
The 1-cope match-plate pattern, template among the 2-, 3-lower bolster, 4-black silicon collagen material feed zone, 5-transparent silica gel raw material feed zone, 6-transparent silica gel shaping area, 7-black silicon gum forming district, 8-plastic stent rest area.
The specific embodiment
For making advantage of the present invention clearer, combine instance that the present invention is described in detail below in conjunction with accompanying drawing.Case description only is to the present invention's explanation that makes an explanation here, but the present invention is not limited only to this instance.This instance is the design of a clamshell phone function key.
ID designing requirement and structure space restriction, coloured lid pad that closes needs to be made of one with the function key support; And the function key character zone has the printing opacity requirement; Batch mixing when preventing the silica gel moulding, and influence outward appearance and function; Common process can only be opened a cover silica gel mould separately with closing the lid pad, will close the lid pad through P+R technology with glue again after the moulding and be made of one with the function key support.But because of closing lid pad too little (the wide 1.5X of long 6.6X is high by 2.1), and silica gel is softer, very easily loses efficacy when causing the very low and reliability of test manufacture examination yield to be tested; The Problem of Failure point mainly contains following item:
1. because bonding area is little, it is very little to cause closing the viscous force that covers between pad and support, is prone to part when drawing and environmental testing;
Since during the silica gel moulding support need put into inorganic agent and soak, could obtain viscous force preferably and must remove some inorganic agents when fitting; And too little because of the fit area, remove effect and be difficult to guarantee unanimity, thereby influence the stability of pulling capacity.
3. too little owing to closing the lid pad, difficulty or ease are in place when causing fitting, and efficient is hanged down and need could be satisfied ordinary production by more manpower.
For improving the problems referred to above point, the present invention realizes in the following manner:
1. the feed zone with three plate silica gel moulds is divided into different zones, is used to place the silica gel pigment of different colours;
2. through calculating and the serious final height of confirming the feed zone barricade, make it and neither can batch mixing during moulding, can fuse the convenient stub bar that takes out after the moulding again;
3. with middle plate that the different silica gel zone of product is separately strict through the lower plate in silica gel three template dies, place moulding silica gel mixed flow, and influence outward appearance and function;
4. make common process into silica gel dijection three template die technologies of the present invention and will close lid pad and be made of one, thereby reduce men hoisting efficient, significantly improved the viscous force that closes lid pad and support.
Fig. 1 is dual-color silica gel shaped structures figure.Employed three template dies comprise cope match-plate pattern 1, middle template 2 and lower bolster 3, and cope match-plate pattern 1 has a plurality of feed zones that are used for the silica gel pigment charging simultaneously of different colours.Said feed zone comprises transparent silica gel raw material feed zone 5 that is positioned at said cope match-plate pattern 1 middle part and the black silicon collagen material feed zone 4 that is positioned at said cope match-plate pattern both sides.Be provided with transparent silica gel shaping area 6, black silicon gum forming district 7 and plastic stent rest area 8 between template 2 and the lower bolster 3 in said.
As shown in Figure 2, its master operation is: key support is put into lower bolster; The middle template of closing; The silica gel of different colours is put into corresponding feed zone; Cope match-plate pattern closes; The silica gel moulding; Product is taken out in die sinking.
