Embodiment
In order further to explain technical scheme of the present invention, below by specific embodiment, the present invention will be described in detail.
As shown in Figures 2 to 6, it is the preferred embodiment that the present invention relates to a kind of production method of frame bracket in mobile phone 100, and this production method comprises the steps:
1. mold, respectively two housings 1, it at least needs to mold structure as shown in Figure 2; Preferably, as shown in Fig. 3, Fig. 4 and Fig. 4 A, also comprise step 1.-1 in the process of moulding housing 1, on housing 1, process the step of die casting groove 11, this die casting groove 11 at least has an outer narrow inner width portion; A kind of concrete structure as this die casting groove 11, as shown in Fig. 4 A, Fig. 9 and Fig. 9 A, this die casting groove 11 is to process by CNC milling machine, concrete, this die casting groove 11 cross section is trapezoidal, this trapezoidal Zhong compare Chang base is positioned at the bottom of die casting groove 11, and this trapezoidal Zhong compare Duan base is positioned at the opening part of die casting groove 11.Certainly these die casting groove 11 China and foreign countries narrow inner width portions can also be other structure, such as adopting metal etching process to process, specifically as shown in figure 10.
2., two housings 1 are placed to respectively in the die cavity of die casting, this die cavity also has headspace after accommodating housing 1, and this headspace communicates with the sprue in die casting;
3., die cast goes out to riddle the supporting member 2 of headspace; Preferably, this step is the multistage that is mutual disconnection shape corresponding to the headspace of same housing 1 in 2., and each reserved section all communicates with the sprue of die casting by corresponding with it runner; As shown in Figure 5, it completes the structural representation forming after this step for the utility model preferred embodiment, as can be seen from the figure, corresponding each supporting member 2 of a plurality of supporting member 2(that is provided with interval shape setting of each housing 1 is all to be formed out by a corresponding reserved section), and each supporting member 2 is connected with thin mouth of a river part 21,21 of Gai Xi mouth of a river parts are for forming out corresponding to runner, 22 of the thick mouth of a river parts ，Qi Yuxi mouth of a river part 21 that forms out corresponding to sprue is connected; More preferably, the length of each supporting member 2 is all less than 1mm, is preferably also greater than 0.8mm; In addition, this step 2. die cavity of middle die casting also has connection chamber, and this connection chamber is for molding the connecting portion 3 of frame bracket in mobile phone 100, and this connection chamber is formed on two corresponding to housing 1 both sides; Thereby connect two housings 1 and make the as a whole parts of whole frame bracket in mobile phone 100 energy.
4., after the demoulding, through water dividing gap, deburring and surface treatment procedure, obtain finished product, as shown in Figure 6; Concrete, this surface treatment procedure can be adjusted accordingly according to actual conditions, and such as in the present embodiment, it can adopt sandblast and anodised operation to make.
Particularly, this step 1. in the moulding of housing 1 be that to take aluminium or stainless steel materials be raw material, by diel punch forming, go out stock, then stock carried out after bending is processed obtaining.
In sum, the production method the present invention relates to, it at least has following beneficial effect:
One, the first one-step forming of frame body being split as to above-mentioned a plurality of step by the one processing and manufacturing of CNC milling machine processes, wherein for the moulding of housing 1 and the die cast of supporting member 2, all there is the feature that production cost is low and production efficiency is high, make thus the production method of whole frame bracket in mobile phone 100 on the basis of dropping into without great amount of cost, can complete the processing and manufacturing of generation in enormous quantities, thereby improve the market competitiveness of enterprise.
Two, the present invention is further because headspace is the multistage that is mutual disconnection shape, so in die cast process, be that supporting member 2 is being become from liquid state in solid-state process, its shrinkage stress can be dispersed, so make housing 1 can, because of being subject to presenting center protrusion shape compared with the impact of large shrinkage stress, can not improve the quality that the method the present invention relates to can be produced finished product.
Three, the present invention is further owing to being also included in the step of processing die casting groove 11 on housing 1, and this die casting groove 11 all at least has an outer narrow inner width portion, so make can make this supporting member 2 to be formed with projection 23 in press casting procedure, by and projection 23 and die casting groove 11 between card join relation, projection 23 cannot be departed from this die casting groove 11, thereby this die cast supporting member 2 out can be positioned on housing 1 securely, further improve and the present invention relates to the quality that method is produced finished product.
Above-described embodiment and graphic and non-limiting product form of the present invention and style, suitable variation or modification that any person of an ordinary skill in the technical field does it, all should be considered as not departing from patent category of the present invention.
