Embodiment Construction

[0018] In this application, the middle frame of the mobile phone is a metal structure, which refers to the whole middle frame of the mobile phone that is formed by forging and CNC (numerically controlled machine tool) to form an outer frame body, and then press-injection-molded in the outer frame body to form an inner frame body. The middle frame of the mobile phone is used to carry the PCB main board, screen components, and batteries of the smart phone. The metal structure of the mobile phone middle frame can effectively improve the strength of the fuselage and stably hold the components of the mobile phone.

[0019] see Figure 1 to Figure 6 As shown, the mobile phone middle frame 10 of the present application includes an outer frame body 11, a holding groove 12 formed on the inner surface 112 of the outer frame body 11 by CNC machining, and an inner frame formed in the outer frame body 11 by die-casting body (not shown). The retaining groove 12 does not pass through the ou...

Abstract

The invention discloses a mobile phone middle frame. The mobile phone middle frame comprises an outer frame body, a retaining groove which is formed in the inner side face of the outer frame body by machining, and an inner frame body which is formed in the outer frame body through die casting, wherein the retaining groove is of a dovetail groove structure being wider at bottom and narrower at the opening; the opening direction of the retaining groove and the outer frame body are at a certain inclination angle; and the inclination angle is between 15 degrees and 30 degrees. Through the application, the defect of inconvenience in machining of the retaining groove in the inner side face of the outer frame body in the prior art can be overcome effectively.

Description

technical field [0001] The present application relates to the field of metal processing, in particular to a middle frame of a mobile phone and a processing method thereof. Background technique [0002] With the trend of ultra-thin and large-screen smart phones, in order to strengthen the overall strength of the mobile phone and improve the user's tactile experience, smart phones have adopted a large-scale metal middle frame as the body. At present, the manufacturing of metal middle frames is generally carried out by forging first and then CNC machining, but the manufacturing cost of this process is very high, and some irregular internal structures are difficult to realize by forging process; there is another commonly used method is Die-casting is used. Although the cost of die-casting is very low, the structure of the middle frame completed by die-casting is not tight enough and the surface gloss is not good. It is usually used for low-end models. [0003] Under such circum...
