Durable, surface aesthetic is wear-resisting.It is main at present to use, aluminum alloy plate materials Digit Control Machine Tool Milling Process, casting forming, Milling Process+
The forming technologies such as casting forming, wherein respectively there is drawback.
Wherein, Digit Control Machine Tool Milling Process has following drawback：Processing efficiency is low, and time length, process is more, and cost is high, product
Size is unstable, and mass production facilities fund input is big, the line brand product shell of existing market two/tri-, because price and the supply of material
Amount problem is difficult to adopt；
And casting forming material and technique are difficult to capture, die casting is the process of typical treatment after pollution, product appearance
Husky hole is produced after milling, impurity, outward appearance trace, heterochromatic after oxidation, and yields is low；It is difficult to meet the outward appearance demand of product, and milling
Cutting housing+be cast into, die casting yield is low, and deflection is big, and negative and positive line after oxidation, milling efficiency and yields are low, is not suitable for big narrow side
And complicated product shaping.
Therefore, it is badly in need of providing a kind of mobile phone center and middle plate shell, to solve the deficiencies in the prior art.
Utility model content
With in consideration of it, the utility model provides a kind of mobile phone center and backboard shell in view of the shortcomings of the prior art.
To achieve the above object, the utility model adopts the following technical scheme that：
A kind of mobile phone center and backboard shell, including backboard shell and center, the backboard shell is using alloy base material as material
Material, it is molded by semi-solid squeeze forming or semisolid pressure casting, is then milled into shape needed for product, the center is with alloy-based
Material is material, be molded by semisolid pressure casting, hot and cold compartment die cast, punch forming, forging forming or machining shaping,
The outer surface of the inner surface of the backboard shell of shaping and the center of shaping is provided with sandblasting layer, the center and it is described in
Plate shell is assembled integrally by fixture, and the center is integrated assembly with the backboard shell by welding fabrication.
More preferably, the material of the backboard shell is selected from 5 series alloys, 6 series alloys or 7 series alloys.
More preferably, the material of the center is pack alloy.
More preferably, it is additionally provided with plastic parts on the assembly.
More preferably, it is additionally provided with anodic oxide coating on the assembly.
More preferably, in the assembly, the fusion penetration ratio of the backboard shell and the center is 1:1.5.
More preferably, the intensity of every square millimeter of the assembly is not less than 10kg.
More preferably, the center is integrated assembly with the backboard shell by electron beam rapid shaping.
Compared with prior art, a kind of mobile phone center and backboard shell of the present utility model have the advantages that:The back of the body
Plate shell is molded using alloy base material as material by semi-solid squeeze forming or semisolid pressure casting, and semi-solid forming reduces material
The mobility of material, is avoided and produces husky hole in the material, and can be stripped without releasing agent, and semisolid pressure casting is molded, be cold
Hot chamber diecasting shaping, punch forming, forging forming or machining shaping are washed technique with pin and combined, and reduce the ratio of milling process
Example, make full use of semisolid pressure casting shaping, hot and cold compartment die cast, punch forming, forging forming or machining shaping work
Skill efficiency high, forming, complicated part can be manufactured, the advantages of cost is low, prepares mobile phone center, with the moulding process of milling
To prepare the mobile phone shell on the back high to appearance requirement, tentatively fixed by fixture, then center passes through welding fabrication with backboard shell
Assembly is integrated, production efficiency is high, and defective products rate is low, can substantially reduce production cost, is adapted to big specification industrialization promotion
Using.
