Concrete, as depicted in figs. 1 and 2, electronic product middle frame of the present utility model comprises outer rim, and this outer rim includes two side frames 1, upper side frame 2 and lower frame 3, and this two side frames 1, upper side frame 2 and lower frame 3 fit tightly and surround one week whole outer rim of formation;
The inner surface of side frame 1, upper side frame 2 and lower frame 3 is provided with back-off mesh 4, this back-off mesh 4 is processed by the mode of electrolysis half-etching, can adhesion be increased, further reduce follow-up mach difficulty, effectively ensure that the bulk strength of center;
Center support body 5 is injected with in outer rim, specifically, that the both sides of center support body 5 and side frame 1 are injection molded into one, form the semi-finished product of center, in the present embodiment, center support body 5 adopts aluminium alloy or magnesium alloy injection mo(u)lding, achieve the variation of structure on the one hand, strengthen this half-finished intensity; The center support body 5 made by aluminium alloy or magnesium alloy on the other hand can effectively be dispelled the heat, and the heat dispersion of the whole center of final molding is improved;
Draw-in groove is provided with at the upper/lower terminal of center support body 5, be positioned at this draw-in groove place and be connected with plastic cement frame, this plastic cement frame is divided into plastic cement frame 6 and lower plastic cement frame 7, the inwall of upper side frame 2 and lower frame 3 is injected with link 9, the material of link 9 is also aluminium alloy or magnesium alloy, link 9 correspondence of upper side frame 2 fits in plastic cement frame 6, link 9 correspondence of lower frame 3 fits in lower plastic cement frame 7, and that is the structure of the link 9 of upper side frame 2 and the link 9 of lower frame 3 and the structure of upper plastic cement frame 6 and lower plastic cement frame 7 are to Corresponding matching.As can be seen from Figure 2, the structure of upper plastic cement frame 6 and lower plastic cement frame 7 is according to the structure of different center support bodys 5, upper side frame 2 and lower frame 3, the shape and structure of its edge side matches with the edge of center support body 5, upper side frame 2 and lower frame 3, which is provided with some irregular holes, for the assembling of follow-up miscellaneous part.
As optimal technical scheme, side frame 1 of the present utility model, upper side frame 2 and lower frame 3 are stainless steel and make, and adopt stainless steel that the structural strength of the whole center of machine-shaping can be made to be greatly improved, and cost is low, outward appearance is beautiful, high-end fashion, noble and inexpensive.Side frame 1, upper side frame 2 and lower frame 3 are provided with key hole, and during for assembling, button puts into.
Middle frame structure of the present utility model, compared with traditional structure, with the etching of stainless steel material strip, punch forming, decreases machining processes, effectively reduces costs, but does not lose quality.And improve intensity, and metal appearance texture processing, there is the very more high-end fashion of strong metal sense.
In order to obtain above-mentioned electronic product middle frame, the utility model by the following method, prepares electronic product middle frame, and concrete process is as follows:
Step 1: choose stainless steel material strip as required, namely chooses stainless steel and makes outer rim, to improve the intensity of whole outer rim;
Step 2: two-sided etching is carried out to stainless steel material strip, concrete, as shown in Figure 3, be adopt electrolytic etching mode especially the mode of electrolysis half-etching carry out etching, mainly etching place back-off mesh 4 on material strip, increases the adhesion of whole material on the one hand, also can reduce follow-up mach operation on the other hand, effectively ensure the intensity of product, show the double-edged etching schematic diagram of stainless steel material strip in Fig. 3;
Step 3: punch forming, the stainless steel material strip being about to etch carries out punching press, the crude green body of final formation outer rim, same, with reference to Fig. 4, after this outer rim final molding, be divided into two side frames 1 and upper side frame 2 and lower frame 3, above-mentioned frame now leaves reference column 8, for steps such as follow-up injection mouldings;
Step 4: machine work refine is carried out to the outer rim crude green body after punch forming, refine antenna line of cut (i.e. the edge of each frame) and reference column 8, mainly deburring, the operations such as leveling, are convenient to follow-up procedure of processing;
Step 5: carry out in-mould injection, first, as shown in Figure 5, the injection mo(u)lding of real centering frame body 5, two side frames 1 are placed in the first mould, afterwards by injection moulding aluminium alloy or magnesium alloy, form center support body 5, afterwards as shown in Figure 6, link 9 is formed to upper side frame 2 and lower frame 3 injection moulding aluminium alloy or magnesium alloy, link 9 needs to form different shapes to mate whole middle frame structure according to design, because be injection mo(u)lding, products formed is now semi-finished product; Afterwards with reference to Fig. 7, semi-finished product and upper side frame 2 and lower frame 3 and link 9 are placed in another one mould and the second mould and carry out second time injection moulding, the material of now injection moulding is plastic cement, and injection moulding forms plastic cement frame 6 and lower plastic cement frame 7; Injection moulding process terminates afterwards, forms final center product crude green body.
Step 6: secondary refine is carried out to the center after injection moulding, the reference column 8 mainly on mill off frame, carries out deburring leveling to profile and key hole further, then carries out chamfering to each periphery of center;
Step 7: surface treatment is carried out to center, this surface treatment can select a under type as required, in the present embodiment, is first carry out wire drawing process or blasting treatment to center periphery, to form the surface configuration of better appearance; Clean afterwards, carry out electric slurry polishing after cleaning terminates, form bright even curface; Carry out PVD plated film or electroplating processes as required afterwards, form fashion, outer surface attractive in appearance more, there is good metal-like.
By this preparation method, the center of formation has the extraordinary feature of intensity, and heat dispersion have also been obtained raising, while not losing quality, reduce processing cost.
Obviously, above-described embodiment of the present utility model is only used to clearly demonstrate the utility model example, and is not the restriction to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all execution modes.All do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., within the protection range that all should be included in the utility model claim.
