Description
Technical field
The present invention relates to mobile phone and manufacture field, in particular, relate to a kind of manufacture method of mobile phone center and a kind of mobile phone center.
Background technology
Along with the raising of the level of consumption, consumer not only focuses on its quality to the requirement of electronic product, also more and more pays close attention to its texture and feel, and the electronic product with special texture and feel commercially has competitiveness more.
At present, most of handset shell adopts plastic production to form on the market.Plastic casing wears no resistance, and uses after a period of time and there will be the situations such as cut even fades, and texture and feel more coarse.In order to solve above-mentioned plastic handset housing Problems existing, increasing mobile phone adopts metal shell, metal-back physical efficiency brings beyond challenge visual impact sense, not only there is feel exquisiteness, wear-resisting, shatter-resistant, the advantage such as anticorrosive, and exquisite appearance, extremely consumer praises highly all the time, represents the developing direction of high-end electronic product.
But existing metal shell generally adopts a block of metal section bar to process, by the restriction of processing method, machine-shaping length consuming time, production cost is high, larger to the volume production restriction of metal shell.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind ofly to cut down finished cost, the manufacture method of the mobile phone center that reduces process time and the mobile phone center that uses the method to manufacture.
The object of the invention is to be achieved through the following technical solutions:
A manufacture method for mobile phone center, comprises the following steps:
S1, employing metallic plate punching become reeded first blank of band;
S2, the spacer processing injection moulding region and be connected with the frame of described first blank on the first blank, obtain the second blank;
S3, carry out in-mould injection in the injection moulding region of the second blank, obtain the 3rd blank;
S4, the frame of the 3rd blank is worked into preset thickness, obtains the 4th blank;
S5, the spacer in the 4th blank to be removed.
Preferably, also comprise in step S1, processing injection moulding connecting hole and assembly fixing hole.The base plate of the first blank is processed injection moulding connecting hole and assembly fixing hole, can when in-mould injection, make stable coupling together between moulding and frame, ensure stability when mobile phone uses, processing assembly fixing hole can allow the face-piece of circuit board of mobile phone, mobile phone or be connected by screw between the drain pan of mobile phone and center, ensures the fastness that mobile phone is installed.
Preferably, step S2 comprises, and while processing injection moulding region, at least one limit on frame processes partition grooves.Frame processes partition grooves, can aided injection mould part be connected with frame stable, and frame can cut off by partition grooves, like this after mobile phone assemble, can reduce the impact of frame on mobile phone signal of metal, the normal work of guarantee antenna for mobile phone.
Preferably, described partition grooves comprises and is separately positioned on the first partition grooves on frame on two minor faces and the second partition grooves.Such setting is because the position residing for two minor faces of frame, all can be provided with antenna for mobile phone, so need to arrange partition grooves on two minor faces of frame, reduces the frame of metal to the impact of mobile phone signal.
Preferably, the preset thickness in step S4 is less than or equal to the degree of depth of described partition grooves.Arrange when can ensure to process frame in S4 like this, when frame is added to preset thickness, frame can cut off at partition grooves place by moulding, thus make frame can not form a continuous print metal frame, so just can reduce the screening effect of frame to mobile phone signal, make mobile phone better receive signal, facilitate the normal operation of mobile phone.
Preferably, also comprise in step S1, the spacer region processing locating hole on the first blank.Locating hole processing, on spacer, in injection moulding with add man-hour, directly can position according to locating hole, facilitate injection moulding and processing.
Preferably, also comprise in step S4, described frame processes side opening.Processing side opening conveniently can install the side switch of mobile phone.
Preferably, step S2 comprises, and when processing injection moulding region and spacer, reserves the brace connected between spacer and the frame of the first blank in injection moulding region; Step S5 comprises, and by cutting off brace, is removed by spacer.Spacer, brace and frame are all one, form blank so more accurate, and the precision of processing is also better, and the yield of finished product also can more be increased.
Preferably, described locating hole is provided with three, and three locating holes lay respectively at leg-of-mutton three summits place.Just blank can be located completely by these three locating holes, thus improve the precision of injection moulding and processing.
A kind of mobile phone center, uses above-mentioned arbitrary manufacture method manufacture.Adopt the mobile phone center that above-mentioned manufacture method manufactures, the cost of manufacture is lower, and the time of manufacture is shorter, and yields is higher, is more applicable to volume production, can meet the demand that modern industry is produced.
The present invention obtains being with reeded first blank owing to first sheet metal to be carried out punching press; Afterwards, the spacer the first blank processing injection moulding region and is connected with the frame of the first blank, obtains the second blank; Then, carry out in-mould injection in the injection moulding region of the second blank, obtain the 3rd blank; Thereafter, the frame of the 3rd blank is worked into preset thickness, obtains the 4th blank; Finally, the spacer in the 4th blank is removed.Adopt this manufacture method, first sheet metal is carried out punching press, and aft-loaded airfoil injection moulding region and spacer, facilitate follow-up processing like this, when carrying out in-mould injection, accurate location when can carry out injection moulding by spacer, to ensure the stable and accurate of injection moulding, when the frame of the 3rd blank is worked into preset thickness, is also undertaken clamping and locating by spacer, can conveniently process, ensure the accurate of processing, finally, spacer is removed, just obtain shaping middle frame structure.In whole process, the allowance of each step has all carried out effective control, and punching press can reduce the allowance of digital control processing, punching press required time is shorter, and cost is lower, and the surplus of digital control processing is thereafter also less, thus shorten the time of processing, reduce the cost of processing.And by the accurate location of spacer, the precision of injection moulding and processing is higher, thus improves the yields of center finished product, so just reduce further the cost of manufacture.
