Description
Technical field
The present invention, relevant for a kind of handset shell method for making and structure thereof, refers to that a kind of sidewall is configured as handset shell method for making and the structure thereof of spill especially.
Background technology
General mobile phone as shown in Figure 1, there is corresponding forward and backward housing, and as shown in side body after in figure, known known handset shell 10 mainly is configured as the structure with spill opening 11 forms, and this handset shell 10 has a diapire 12 of relative this opening 11 and a sidewall 13 that connects this opening 11 and this diapire 12; It should be noted that, as shown in Figure 2, known known handset shell 10 processing procedures generally need to coordinate a molding tool A to complete forming step, wherein, as shown in Figure 2, the relative both sides of opening 11 that define this spill handset shell 10 have a wide cut W, and there is a distance B between these sidewall 13 relative both sides inner faces 131, by this, known known handset shell 10 finished products are in order to facilitate from the mould A demoulding, its sidewall 13 must be configured as the vertical wall form, makes the opening 11 wide cut W of handset shell 10 have the length suitable with sidewall 13 distance B.
Quite variation of 3C Product at present, as attracting the consumer, the outward appearance that how has the design sense become one of key affected sales volume, though there is the mobile phone products designer design variation to be extended on the sidewall 13 and diapire 12 joint line forms of handset shell 10, yet, after considering to reduce manufacturing cost, as having opening 23 wide cut W, Fig. 3 is less than sidewall 22 ultimate range D
maxHandset shell 20 forms, because the problem of demoulding difficulty is arranged, cause known known handset shell 10 sidewalls 13 de-aforementioned vertical wall form yet, form the restriction of handset shell 10 appearance designs, therefore known known handset shell method for making space real to be improved.
Summary of the invention
The object of the present invention is to provide a kind of handset shell method for making and structure thereof of tool concave side walls, it is mainly to using to contain the moulding material of the fibrage of resin pickup as handset shell, the mould that cooperation forms with elasticity internal mold and hard external mold, make the opening wide cut of handset shell be less than the side wall inner surface distance, reach the purpose that forms concave side walls in handset shell.
For reaching above-mentioned purpose, according to the handset shell method for making of a kind of tool concave side walls provided by the present invention, this recipe step comprises:
(a) external mold manufacturing step: get a hard block and be arranged with a die cavity, defining this die cavity, to be arranged with direction be a Z direction, and a bottom surface of this die cavity is the face that an orthogonal directions X and a Y-direction form, this die cavity has a wall and forms in its bottom surface periphery, the variation that makes this wall have Y-direction on this X-Z face changes (Δ y) and have the variation variation (Δ x) of directions X on this Y-Z face, is configured as a hard external mold of curved-surface structure to manufacture the die cavity wall; (b) internal mold manufacturing step: get an Elastic Block to the die that should external mold die cavity shape be shaped, to manufacture an elasticity internal mold and this external mold to synthetic a molding tool; (c) the impregnation fibrage enters the mould step: bottom surface and wall prior to this external mold die cavity attach an impregnation fibrage, then insert this elasticity internal mold die and really be close to bottom surface and the wall of this external mold die cavity with extruding impregnation fibrage; (d) hot briquetting step: getting a vacuum glued membrane, to be coated at this mould outside and vacuumize and make this external mold and this internal mold close apposition, and this elasticity internal mold and this impregnation fibrage push mutually, make this internal mold elasticity reduce with this external mold and the impregnation fibrage is shaped as to the handset shell shape of tool concave side walls, then this impregnation fibrage heat hardening is configured as to the flexible handset shell finished product of tool; (e) demoulding step: remove this vacuum glued membrane, this external mold die cavity takes out this elasticity internal mold certainly, and the mat elastic deformation takes out this handset shell finished product, take and makes the handset shell that sidewall is concave structure.
Further, the preimpregnation of described impregnation fibrage plural number fibrage in conjunction with glue after mutual stacking moulding person.
Further, described fibrage is carbon fiber or glass fibre.
Further, in described external mold manufacturing step, the wall of described external mold die cavity encloses the cave mouth that is shaped, and defines the place, relative both sides of described external mold die cavity, there is a wide cut between the mouth periphery of described cave, and there is a ultimate range between described wall and be greater than described cave mouth wide cut.
Mobile phone casing structure according to a kind of tool concave side walls provided by the invention, this handset shell is arranged with the space that is shaped, defining this space, to be arranged with direction be a Z direction, this handset shell is in this space bottom one diapire, defining this diapire is the wall that an orthogonal directions X and a Y-direction form, one sidewall forms in this diapire week side, makes this sidewall have the variation (Δ y) of Y-direction on this X-Z face and have the variation (Δ x) of directions X on this Y-Z face.
Further, described handset shell sidewall encloses the opening that is shaped, and defines place, the relative both sides of described handset shell, between described opening periphery, has a wide cut, and has a ultimate range between described sidewall wall and be greater than described wide cut.
So, the present invention sees through above-mentioned method for making, and reach the shaping side wall construction and change various handset shell, and the use of mat elasticity internal mold, not only break through the problem that known handset shell processing procedure is limited to demoulding step, and the handset shell that moulding has concave side walls really and rapidly.
Relevant for the present invention, for reaching above-mentioned purpose, the technology adopted, means and other effects, hereby lift a better possible embodiments and coordinate graphic being described in detail as follows.
