Embodiment
The technical solution of the utility model is further illustrated by embodiment below in conjunction with accompanying drawing.
Embodiment 1
A kind of middle frame structure, as shown in Figure 1, middle frame structure comprises frame 1 and injection moulding plastic structure 7, injection moulding plastic structure 7 is overlying on middle plate 2, and frame 1 is divided into multistage segmentation frame 3, forms antenna slot segmentation 9 between adjacent sectional frame 3, in segmentation frame 3, plate 2 edge is arranged, and is connected with middle plate 2.
The material of frame 1 is stainless steel, and the material of middle plate 2 is stainless steel, to ensure the strength demand of middle frame structure.
Frame 1 is provided with earpiece holes 4, USB hole 5 and key hole 8.
Injection moulding plastic structure 7 is that frame 1 and middle plate 2 are adopted insert injection molding and formed.
The production technology of this middle frame structure, comprises the following steps:
Step one, shaping frame 1 and middle plate 2, wherein, frame 1 comprises the discrete segmentation frame 3 of multistage, and 1 point, frame is in order to 3 sections of segmentation frames 3 in the present embodiment, and as shown in Figure 2, middle plate 2 is shaping by Sheet Metal Forming Technology, and the schematic diagram after shaping is as shown in Figure 3;
Step 2, the frame 1 after shaping by step one and middle plate 2 are assembled fixing, segmentation frame 3 along in plate 2 edge arrange, form antenna slot segmentation 9 between adjacent sectional frame 3, as shown in Figure 4, the connected mode between segmentation frame 3 and middle plate 2 is welding, bolt connects or riveted joint;
Step 3, first time machine work, be included in shaping earpiece holes 4, USB hole 5 on frame 1, and finish-milling is carried out to antenna slot segmentation 9 or frame 1, then by middle plate 2, the part that follow-up in-mode inserts injection mo(u)lding is unnecessary is excised, the multiple holes 6 arranged along frame 1 are formed, as shown in Figure 5 after unnecessary Partial Resection;
Step 4, in-mode inserts injection mo(u)lding is carried out to the frame 1 formed in step 3 and middle plate 2, form injection moulding plastic structure 7, as shown in Figure 6.Insert injection molding refers to load resin by injection after pre-prepd different material inserts in mould, and the material of melting and inserts engagement cure, make the forming method of integration product;
Step 5, second time machine work are finish-milling frame 1 side outer surface, key hole 8 or chamfering place, as shown in Figure 7;
Plate 2 in step 6, cutting, to not carry out the Partial Resection of insert injection molding in the middle part of described middle plate 2, the middle part of middle plate 2 is cut, forms the middle frame structure comprising frame 1 and injection moulding plastic structure 7, injection moulding plastic structure 7 is overlying on not cut middle plate 2, obtains middle frame structure;
