In an alternative embodiment of the present invention, the first tab 102 and the second tab 103 are of different lengths. As shown in fig. 3, the first fold 102 of the left titanium alloy strip is shorter relative to the second fold 103. Of course, in other examples, the lengths of the first flap 102 and the second flap 103 may be the same.
After the titanium alloy strip is bent to a predetermined size to form a shape shown in fig. 3, the outer frame 100 is subjected to numerical control processing, as shown in fig. 4, in order to facilitate matching with the middle plate 200, the outer frame 100 is further provided with a plurality of matching tables 110, matching holes 120 and matching recesses 130 which are machined by CNC, the matching tables 110 are used for bearing the middle plate 200, and the matching holes 120 and the matching recesses 130 are used for receiving the first plastic 300 for filling. Wherein, the matching table 110 comprises a transverse matching table 111 and a longitudinal matching table 112, and the transverse matching table 111 is used for holding the middle plate 200. The longitudinal mating table 112 is adapted to be insert mated with the injection molding hole 210 of the intermediate plate 200. In addition, necessary structures such as a charging groove, a side strengthening groove, an audio jack and the like can be processed on the titanium alloy strip, and the details are not described since the invention point is not involved.
Referring to fig. 5, in the embodiment of the present invention, the middle plate 200 is preferably an aluminum plate, which has the characteristics of light weight and easy processing and is formed into a predetermined shape by stamping, and as shown in fig. 6, the middle plate 200 is stamped to form a plurality of injection holes 210. The plurality of injection molded holes 210 may include half holes and full holes provided at the edges.

Referring to fig. 10, the phone frame further includes a second plastic 400, and the second plastic 400 is filled from the injection hole 310 of the first plastic 300, wherein the material used for the second plastic 400 is different from the material used for the first plastic 300, the material used for the first plastic 300 mainly plays a role in fixing and connecting, and the material used for the second plastic 400 is beneficial for transmission of wireless signals.
Referring to fig. 11, finally, unnecessary plastic is removed and shaped, the wall of the injection hole and the excess plastic filler are removed, and the CNC is used to machine the smooth-transition outer contour.
The invention can improve the processing efficiency of the mobile phone shell and simultaneously improve the product quality of the mobile phone shell.
Different from the traditional method for manufacturing the mobile phone frame, the mobile phone frame is processed into two parts, namely the outer frame 100 and the middle plate 200, wherein the outer frame 100 is made of a high-hardness material (such as titanium alloy), the middle plate 200 is made of an aluminum material (titanium alloy can be adopted, cost is mainly considered, and the high-hardness material is not required in the mobile phone), and the processing technology is as above, so that on one hand, the whole aluminum plate is not required to be machined, but the titanium alloy section is cut, and the middle plate 200 is stamped, so that the processing time is saved, and the efficiency is improved; meanwhile, the outer frame 100 is made of a high-hardness material, so that the mobile phone shell is firmer, not easy to deform and not easy to scratch.
The invention has the advantages of less processing amount, short processing time and the like, and avoids the defects of difficult surface treatment and the like caused by the incompact material of the die casting, and the like.
In addition, the invention also provides a mobile phone, which comprises components known by persons skilled in the art, such as a screen, a circuit board unit, a battery module and the like, and the mobile phone frame, wherein the battery module supplies power to the screen and the circuit board unit, and the mobile phone frame supports the installation of the screen, the circuit board unit and the battery module.
Referring to fig. 12, fig. 12 is a flowchart of a method for manufacturing a frame of a mobile phone according to a preferred embodiment of the invention.
The invention also provides a manufacturing method of the mobile phone frame, which comprises the following steps:
and S110, bending the titanium alloy strip material to form an outer frame according to a preset size. In this step, the outer frame may be folded from one strip of titanium alloy, or the outer frame may be folded from two strips of titanium alloy as shown in fig. 6.
And S120, processing the outer frame to form a mounting structure.
And S130, performing stamping treatment on the aluminum intermediate plate.
And S140, fixedly connecting the outer edge of the middle plate and the inner side wall of the outer frame in an injection molding mode by using first plastic.
S150, machining an end groove through CNC (computer numerical control) on the outer frame, and forming an injection molding hole in the first plastic at the end groove.
And S160, filling the second plastic from the injection molding hole on the first plastic.
And finally, removing and cleaning unnecessary plastic, and machining the smoothly-transitional outer contour through CNC.
The material used by the second plastic is different from the material used by the first plastic, the material used by the first plastic mainly plays a role in fixed connection, and the material used by the second plastic is beneficial to the transmission of wireless signals.
In summary, those skilled in the art can easily understand that the mobile phone frame provided by the present invention adopts the titanium alloy outer frame and the aluminum intermediate plate and is fixed by injection molding, so that the mobile phone frame has the advantages of simple structure, relatively less processing workload, relatively shorter processing time, high efficiency, high yield, high material utilization rate, convenient manufacture, reliable strength and exquisite appearance. Because the hardness of the titanium alloy is far greater than that of the aluminum alloy, the mobile phone frame made of the titanium alloy is more difficult to scratch, and the mobile phone frame is fixed in an injection molding mode, then is subjected to CNC (computerized numerical control) processing, and then is subjected to secondary injection molding, so that the processing consistency and accuracy are ensured.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
