Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is a part of embodiment of the invention, rather than whole embodiments.Based on this hair
Embodiment in bright, the every other implementation that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example, belongs to the scope of protection of the invention.
The embodiment of the present invention provides casing manufacturing method after a kind of mobile terminal, as shown in figure 1, shell is manufactured after the mobile terminal
Method includes：
Shell mould after step S1, one mobile terminal of offer.
Exemplarily, shell mould can be shell mould after mobile phone battery cover mould, tablet personal computer etc., ability after the mobile terminal
Field technique personnel can be selected according to the actual requirements, and those skilled in the art can also select according to actual conditions and open vertically
The mould of mould or the level die sinking of mould.
Step S2, light metal alloy melt filled into type into shell mould after mobile terminal, die casting formed it is preforming it is mobile eventually
Shell behind end.
It should be noted that " light metal " signified in the embodiment of the present invention is that well known to a person skilled in the art density
Metal less than 4500 kilograms per cubic meter, such as aluminium, magnesium, potassium, sodium, calcium, strontium, barium, exemplarily, above-mentioned light metal alloy
Melt can be Al-Si alloy melt or mg-si master alloy melt etc..Those skilled in the art can be according to actual manufacture demand from tool
The light metal alloy of body, the embodiment of the present invention is without limiting.
Step S3, to after preforming mobile terminal shell carry out closed die forging, formed mobile terminal after shell.
After the mobile terminal that the present embodiment is provided in casing manufacturing method, light metal alloy melt is filled into type to a set of movement
After terminal in shell mould, die casting is formed after preforming mobile terminal after shell, you can to the preforming movement in same mould
Shell carries out closed die forging after terminal, forms shell after mobile terminal.It follows that shell after mobile terminal provided in an embodiment of the present invention
Manufacture method manufactures shell phase ratio after mobile terminal with existing use CNC machine, can avoid to preforming mobile terminal
The multiple clamping position of shell, so as to simplify the manufacturing process of shell after mobile terminal, effectively reduces shell after mobile terminal afterwards
The manufacturing process cost of shell after finished product machining period, reduction mobile terminal.
You need to add is that, by closed die forging, it can also make the crystal grain refinement after mobile terminal inside shell, sbrinkage blowhole is notable
Reduce, evaded using CNC machine manufacture mobile terminal after shell when, because multi- pass rolling and caused by mobile terminal after shell crystal grain
It is thick, the serious defect of material line.Further, since the crystal grain refinement after the mobile terminal produced inside shell, and hence it is also possible to right
Shell is heat-treated after the mobile terminal, further to improve the intensity and hardness of shell after the mobile terminal, strengthens the movement whole
Wearability behind end.
Exemplarily, above-mentioned that light metal alloy melt is filled into type into shell mould after mobile terminal, die casting forms preforming
Shell concretely comprises the following steps after mobile terminal：Light metal alloy melt low speed is filled into type into shell mould after mobile terminal, die casting shape
Shell after into preforming mobile terminal.It should be noted that " low speed " signified in the embodiment of the present invention is people in the art
Member is known：10cm/s~15cm/s.Compared with high speed fills type, light metal alloy melt low speed is filled into type to shell after mobile terminal
In mould, it can make it that volume gas and stomata after the mobile terminal to be formed inside shell are less, so as to be conducive to shaping is various to have
Shell after the mobile terminal of complex internal shape.
Preferably, as shown in Fig. 2 from shell after the Making mold mobile terminal molded vertically, specifically, the mobile terminal
Shell mould includes afterwards：Mould mo(u)ld top half 1, mold cavity 2, mould mo(u)ld bottom half 3, mold closing forging and stamping drift 4, push rod 5, running channel 6, horizontal pressure chamber
7th, pouring slot 8 and injection tup 9.When using shell after the Making mold mobile terminal, controllable injection cuts somebody's hair 9, passes through level
Light metal alloy melt is filled type into mold cavity 2 by pressure chamber 7 and running channel 6, and in the vertical direction completes closed die forging.With making
The mould molded with level is compared, and because the pressure chamber in the mould that molds vertically is horizontal pressure chamber, therefore, can be cut somebody's hair by injection
Control the filling velocity of light metal alloy melt, it is to avoid the filling velocity of light metal melt is too fast, the mobile terminal resulted in
The more situation of volume gas and stomata afterwards inside shell occurs, so as to be conducive to the shaping various mobile ends with complex internal shape
Shell behind end.
Exemplarily, as shown in figure 1, casing manufacturing method may also include after above-mentioned mobile terminal：
Step S4, to after mobile terminal shell carry out Shape correction.
Further, the specific steps that shell after mobile terminal carries out Shape correction may include：
Step S41, to after mobile terminal shell carry out trimming, obtain shell after the mobile terminal after trimming.
Step S42, using anode oxidation process shell after the mobile terminal after trimming is surface-treated.
It should be noted that when being surface-treated to shell after the mobile terminal after trimming, can also be using spray painting, baking vanish etc.
Technique, and due in casing manufacturing method after mobile terminal provided in an embodiment of the present invention, preferably by light metal alloy melt low speed
Type is filled into shell mould after mobile terminal, therefore, if during from Al-Si alloy melt, can select the relatively low alusil alloy of silicone content
Melt, specifically, the mass content of silicon is less than or equal to 6% in the Al-Si alloy melt of selection, so that producing
Mobile terminal after shell anode oxidation process can be applicable to be surface-treated, add what shell outward appearance after mobile terminal was handled
Possibility, also improves the overall quality of shell after mobile terminal.
The embodiment of the present invention also provides shell after a kind of mobile terminal, and shell uses shell after above-mentioned mobile terminal after the mobile terminal
Manufacture method is manufactured.
The beneficial effect of shell and casing manufacturing method after above-mentioned mobile terminal after mobile terminal provided in an embodiment of the present invention
Beneficial effect is identical, therefore is no longer repeated herein.
In addition, the present invention also provides a kind of mobile terminal, the mobile terminal includes shell after above-mentioned mobile terminal.
The beneficial effect of mobile terminal provided in an embodiment of the present invention is identical with the beneficial effect of shell after above-mentioned mobile terminal,
Also no longer repeated herein.For the other components of the mobile terminal, those skilled in the art can refer to existing shifting
Dynamic terminal is configured, and the present invention is implemented without limiting.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
Those familiar with the art the invention discloses technical scope in, change or replacement can be readily occurred in, should all be contained
Cover within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
