Abstract
The invention discloses a hand-held communication device front casing manufacturing method. The steps are that: at least a patterned film is disposed into a first female mould; plastic is poured into a first male mould and the first female mould and then the plastic is jetted to be molded into an embryo which is firmly combined with the film to form a window glass; the first male mould and a second male mould are rotated and replaced after the moulds are opened so as to make the window glass move with the first male mould; another film is disposed in the first female mould and at the same time the mould is closed so that the plastic can be poured into the moulds; the plastic is jetted and forms a first front casing in the first male mould and the first female mould, and another window glass is formed in the second male mould and the first female mould, then the front casing is taken out. Compared with prior art, the method is dispensed with the making process of the back-adhesive area and the adhibitting process. With the invention, the thickness of the whole body can be reduced and the assemblage can be simplified.
Description
Technical field:
The present invention relates to a kind of front casing manufacturing method of hand-holding communication device, refer to a kind of processing procedure that forming technique combines with the double-material jet formation technology in the film that utilizes especially.
Background technology:
Generally speaking, hand-holding communication device such as mobile phone comprise a fore shell, and fore shell has a window eyeglass and a shell.(In-Mold Film IMF) makes the window eyeglass, and it is printed on the surface of plastic sheeting in the ink printing mode with required pattern, after high-pressure forming, will become required appearance and size with the film slitting of pattern again with the in-molded technology of film.And will insert in the jetting mold with the film of pattern by artificial or mechanical system, plastics are combined closely through penetrating with the film with pattern, are finished product after the taking-up.
Shell can utilize pure ejection forming technique or double-material jet formation technology (doubleinjection) to make, the thin material ejection formation cooperates a mold to carry out the plastic product moulding with the thin material pipe of plastics Jet forming machine, the product taking-up that just can be shaped after once penetrating.Double-material jet formation mainly cooperates two molds with the extra quality pipe of extra quality plastic molding press, makes extra quality double-colored product through twice moulding sequentially, can use different plastics to reach integrally formed manufacture.As shown in Figure 1, mould 10 and mould 20 comprise an identical shaped male model (11,21), the operating type that opening and closing mould and the rotation simultaneously of each difform master mold of arranging in pairs or groups (12,22), two moulds (10,20) replaced.The mould of this kind form is because of using two kinds of plastics, so adopt difference to advance the cast gate injection moulding; And on business mould is identical, adopts sub marine gate to carry out injection moulding in male model (11, a 21) side usually; If mould (10,20) is provided with slide block structure, slide block structure can be incorporated into master mold (12, a 22) side.Its forming step is as follows:
A, two molds (10,20) have a male model (11,21) and a master mold (12,22) can be superimposed with each other each other.
B, allow the mould closure become the matched moulds state, at this moment, plastics can be flow into the internal mode chamber 13 of 12 of male model 11 and master molds, allow 14 moulding of part idiosome.
C, allow mold open become die opening state, make male model (11,21) rotation, and master mold (12,22) maintains static, last position of rotation will make male model 11 and master mold 22 collocation, and male model 21 and master mold 12 collocation, and part idiosome 14 is also along with male model 11 displacements.
D, allow the mould closure become the matched moulds state, and simultaneously plastics are flow into the internal mode chamber (13,23) of mould, and in male model 11 and master mold 22, make an extra quality or double-colored shell 24, and in another group male model 21 and master mold 12, make another part idiosome 15 simultaneously.
E, allow the mould die sinking, take out shell 24.
As shown in Figure 2, be that 24 on window eyeglass 30 and shell are combined into one it with adhesive tape 31 with above-mentioned finished product, only this kind combination needs unnecessary plastics as attach area, can't reduce integral thickness.Moreover window eyeglass 30 must can be reached by two Jet forming machines and two molds with the forming method of shell 24, this shows that two make-up machine and gum mode will be brought extra cost and time, must add consideration.
Summary of the invention:
Technical problem to be solved by this invention is: at above-mentioned the deficiencies in the prior art, a kind of front casing manufacturing method of hand-holding communication device is provided, utilize in the film forming technique to combine and make integrated fore shell, can remove in the prior art processing procedure from the gum attaching with the double-material jet formation technology.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of front casing manufacturing method of hand-holding communication device, this method utilizes a Jet forming machine molded and shaped by plastics injection set of molds, this set of molds has first male model, second male model of identical shaped and rotatable replacement, reaches difformity and fixed first master mold, second master mold; This front casing manufacturing method comprises:
A, provide and have one at least with the film of pattern;
B, this film is inserted first master mold with artificial or mechanical system;
C, plastics are flow in the first public film and first master mold, plastics allow idiosome moulding and combine closely with film and make a window eyeglass through ejaculation;
This first male model and second male model are replaced in d, rotation, force the collocation of this first male model and second master mold, and second male model and the collocation of first master mold, this window eyeglass is then along with the first male model displacement;
E, another film is inserted first master mold with artificial or mechanical system;
F, simultaneously plastics are flow in this set of molds separately, plastics are made a fore shell through penetrating in first male model and second master mold, and make another window eyeglass simultaneously in second male model and first master mold; And
G, taking-up fore shell.
Compared with prior art, advantage of the present invention is:
1, reduces thickness:, can reduce integral thickness because of reducing gum of the prior art zone.
2, simplify assembling process: can remove the processing procedure with artificial secondary assembling (gum attaching) of the prior art from, can save built-up time and manpower.
3, promote intensity: one-body molded and have enough intensity.
4, reduce cost: only need a double-material jet formation machine.
5, reduce the loss of yield.
