Description
Technical field
The invention belongs to Cellphone Accessories technical field, be specifically related to a kind of mobile phone frame support body anode process after the processing of fine aluminium housing implantation compression mod connecting shaping obtained and preparation method thereof.
Background technology
Current numerous high-end consumer electronics metal shell, the middle frame support of especially high-grade mobile phone is all adopt fine aluminium section bar or stainless steel materials, and first makes it process type through CNC milling machine to go out basic frame structure.
Wherein for this technique of numerical control mill, especially the section bar that employing one is complete is by multiple working procedure straight forming, that is to say housing and the as a whole structure of inside casing, it is very high to the requirement on machining accuracy of equipment, and also have process-cycle length, the equipment that takies is many, waste of raw materials is many, fraction defective is high and high in cost of production is not enough, once a certain customer demand is large, being limited to output can be not enough, first must configure a large amount of CNC milling machine equipment, early investment is excessive, is one huge threshold to medium-sized and small enterprises.
For above difficult point, enterprise is had to consider with die casting production integration outside framework, but die casting almag out, its rough surface, and there is the defect such as sand holes, impurity, in addition based on the characteristic of alloy itself, anode oxidation process cannot be adopted to obtain the appearance of high-quality, namely cannot reach the designing requirement of numerical control mill technique.
Existing almag die casting cannot obtain good appearance when doing anode process, and the process of fine aluminium anode can have beautiful appearance but not be suitable for die cast.Consumer electronics high-grade on market does anode process, cost intensive, inefficiency after adopting pure aluminum plate machined.
Summary of the invention
In order to solve the problem, an object of the present invention is to provide a kind of mobile phone frame support body, the appearance of high-quality can be obtained, reach the designing requirement of numerical control mill technique, there is the advantage that the process-cycle is short, the equipment that takies is few, percent defective is low, cost-saving simultaneously.
Two of object of the present invention is the preparation method providing described mobile phone frame support body.
The present invention is achieved through the following technical solutions:
A kind of mobile phone frame support body, comprise housing and be located at the center body in described housing, the outer rim of described center body is connected on the inner edge of described housing; Described housing is fine aluminium part, and described center body is die-casting magnalium alloy.Wherein, the aluminum component that housing uses is preferably 5 is that more preferably housing adopts AL6063 material to 7 aluminium alloys being or more; Center body selects ADC10, ADC12, AZ91D.5 is make housing to 7 aluminium alloys being or more can meet outward appearance exquisiteness, there is not the requirement of the high-quality such as sand holes, impurity, the percent defective produced when die-casting magnalium alloy also reduces and uses aluminium alloy as the cost of center body as center body simultaneously and reduce die casting simultaneously.
Preferably, groove is respectively equipped with inside the described long limit of housing two.
Preferably, described groove structure rectangular in cross-section.Further, the groove depth of described groove can not be less than 0.3mm, can not be greater than 1/2 of housing design width.
Preferably, the incomplete closed pores of each reserved more than a group on two minor faces of described housing.These apertures are used as inside casing die casting and draw glue to be connected between housing to use.
Preferably, describedly often organize incomplete closed pores and have 4 to 5; Further, the diameter of described each incomplete closed pores is 1mm, and the centre distance edge in hole is 0.3mm.
Prepare the method for described mobile phone frame support body, it is characterized in that:
A. drill two holes on one block of aluminium alloy, using these two holes as locating hole, uses CNC milling machine to mill out the general profile of housing;
B. inside two long limits, used by housing obtained above T cutter to mill out two grooves 21, groove depth can not be less than 0.3mm, can not be greater than 1/2 structure of housing design width;
C. housing obtained above is needed on two minor faces the incomplete closed pores of each reserved more than a group;
D. housing is inserted in compression mod, reserved locating dowel in compression mod, after coordinating with the locating hole in A operation, the runner space that mold cavity should communicate with die casting sprue in addition after holding housing;
E. inject magnadure, die cast goes out the center body in headspace;
F. after the demoulding, the removal mouth of a river is carried out to inside casing, the operation of polishing burr;
G. behind location, to excision housing redundance, and carry out High Speed Milling Operation, mill out appearance and bevel edge on CNC milling machine;
H. sandblasting and anodized are carried out to appearance, the mobile phone frame support body of the color standard that finally met the requirements of the customers.
Further, if there is requirement height light chamfering, need after F step, use CNC milling machine chamfering again.
The present invention includes housing and be located at the center body in described housing, the outer rim of described center body is connected on the inner edge of described housing; Described housing is fine aluminium part, and described center body is die-casting magnalium alloy.The one-body molded manufacture of numerical control of existing mobile phone framework is split as several step process, first to be made by machined by the simple housing of structure or extruded obtained, the housing of having reprocessed puts into mould, utilizes die casting to obtain the center body of structure relative complex.The present invention, in conjunction with fine aluminium and almag die casting good characteristic separately, manufactures quality product, reduces costs, raise the efficiency, and improves product competitiveness in the market, meets the designing requirement of high-end handsets to high-quality outward appearance.Relative to consumer electronics high-grade on market for ensureing that appearance does anode process after adopting pure aluminum plate machined, product structure Partial Feature is many, relative complex, machined length consuming time, and cost is high, and efficiency is low.Fine aluminium part of the present invention and almag die casting in conjunction with die-casting and molding technology in mould by the structure division of product complexity by die cast, anode performance excellent for fine aluminium and the good die casting performance of almag are perfectly combined, reduce by 50% machining time, raising efficiency, reduce costs.
