Technical field
The present invention relates to a kind of forming method of complex fiber material shell and its mould, special
It is not to be related to a kind of hot-press molding method of complex fiber material shell and its mould.
Background technology
Now the designer trends of electronic product emphasize lightening, and towards portable production development；With
Adopt the plastic shell of ejection formation toward electronic product, but the thickness considering plastic shell is less than
During 2mm probably due to the problems such as intensity is not enough and be easily broken damage and should not be thinned again, because
This, actively seek other more appropriate materials in recent years, for example excellent and outer using mechanical property
See the shell to prepare electronic product for the good carbon fibre composite.
Carbon fiber is mainly impregnated with heat by the processing procedure for preparing the carbon fibre composite of shell
After thermosetting resin forms a pre-impregnated article, then this pre-impregnated article is placed in mould it is hot pressed into
Type, forms a carbon fibre composite.Due to electronic product shell generally for again with other
Element is sealed, therefore the inner face of shell need to be provided with the structures such as such as bolt or keeper
(what i.e. industry was commonly called as buries nail), during previously used plastic shell, can be in plastic shell shaping
Meanwhile, directly using the mode of ejection formation, bolt or keeper are penetrated and be wrapped in plastic shell
On, but carbon fibre composite is to carry out hot pressing through mould, with existing processing procedure and mould
Design, and cannot in the hot pressing program making carbon fibre composite, directly by bolt or
Keeper carry out hot binding it is therefore desirable to first hot-forming go out carbon fibre composite, then enter
Bolt or keeper are incorporated on carbon fibre composite the program of row ejection formation.Also
It is to say, existing mode, it is necessary to carry out secondary operation, not only improves manufacturing man-hours and cost,
And secondary operation is also likely to result in the accumulation of error amount, it is unfavorable for the design of miniaturization structure.

The location division that die cavity protrudes.This placement step is will be placed below for this male model, and makes this pressing part
And this location division is upward, by positioning piece placement positioning on this location division more compound by one
Fibrous material is positioned on this pressing part and covers this keeper, and this complex fiber material has one
Individual fibrage, and a thermoset resin layer, and be towards this pressure with this thermoset resin layer
The direction in portion processed is placed.This heat-press step is that with this die cavity direction directed downwardly, this master mold is placed in this
The top of male model, then this male model and the combination of this master mold are carried out hot pressing, make this keeper in hot pressing
Directly in conjunction with being positioned on this complex fiber material during shaping.This demoulding step is by this
Male model and this master mold separate, you can obtain one and be combined with outside the complex fiber material of this keeper
Shell.
It is preferred that the hot-press molding method of aforementioned complex fiber material shell, wherein, this is combined
The thermoset resin layer of fibrous material has a thin layer area, and at least one thickness is thin more than this
The thick-layer area in floor area, in this placement step, is that this complex fiber material is positioned over this compacting
In portion, and this keeper is covered with this thick-layer area.
Further object is that providing a kind of aforementioned hot-press molding method of cooperation to use
Heat pressing and molding mold.
The heat pressing and molding mold of complex fiber material shell of the present invention, comprises one and has a die cavity
Master mold, an and male model that can work in coordination with this master mold.Wherein, this male model has a court
To this master mold die cavity protrude pressing part, and at least one by this pressing part towards this master mold
The location division that die cavity protrudes.
It is preferred that the heat pressing and molding mold of aforementioned complex fiber material shell, wherein, this male model
Also there is the spout hole that at least one depression is formed on this pressing part.
The beneficial effects of the present invention is: by above-mentioned design, complex fiber material is being carried out
Once in hot-forming program, just directly can be combined with positioning piece and form a composite fibre
Material envelope, reduces production process, reduces production cost, and improve Product Precision.
Brief description
Fig. 1 is a flow chart, and the hot-press molding method of complex fiber material shell of the present invention is described
Embodiment；And
Fig. 2 is a schematic diagram, aids in illustrating Fig. 1.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment the present invention is described in detail.
Refering to Fig. 1,2, the embodiment of the hot-press molding method of complex fiber material shell of the present invention,
Comprise steady step 21, a placement step 22, a heat-press step 23, and a demoulding step
24.
This preparation process 21 is a male model 3 and the master mold 4 preparing to work in coordination, wherein, should
Master mold 4 has a die cavity 41, and this male model 3 has a die cavity 41 towards this master mold 4
Protrude pressing part 31, and at least one by this pressing part 31 towards this master mold 4 die cavity 41
The location division 32 protruded.In the present embodiment, it is taking a location division 32 as a example to illustrate and paint
Show it is of course possible to design quantity and the distributing position of this location division 32 depending on actual demand, not with
Disclosed by the present embodiment, person is limited.
This placement step 22 is will be placed below for this male model 3, and makes this pressing part 31 and this is fixed
Position portion 32 upward, by positioning piece 5 placement positioning on this location division 32, then one is combined
Fibrous material 6 is positioned on this pressing part 31 and covers this keeper 5, this complex fiber material
6 have a fibrage 61, and a thermoset resin layer 62, and are with this thermoset resin layer
62 place towards the direction of this pressing part 31.To be illustrated, this complex fiber material
6 thermoset resin layer 62 has a thin layer area 621, and a thickness is more than this thin layer area
621 thick-layer area 622.The thickness in this thick-layer area 622, quantity and position are to coordinate this positioning
Part 5 and design, therefore can coordinate quantity and the distributing position of keeper 5.
In this placement step 22, it is that this complex fiber material 6 is positioned over this pressing part 31
On, and this keeper 5 is covered with this thick-layer area 622.
This heat-press step 23 is that with this die cavity 41 direction directed downwardly, this master mold 4 is placed in this male model
3 top, then this male model 3 and this master mold 4 combination are carried out hot pressing, make this composite fibre material
The thermoset resin layer 62 of material 6 is heated after thawing, and this thick-layer area 622 can more intactly
Cladding positions this keeper 5, and then makes this keeper 5 direct during hot-forming
In conjunction with being positioned on this complex fiber material 6.In addition it is noted that this male model 3 also has
One depression is formed at the spout hole 33 on this pressing part 31, for for unnecessary thawing resin
Overflow, to avoid affecting the structure of finished product.
This demoulding step 24 is to separate this male model 3 and this master mold 4, you can obtain a combination
There is the complex fiber material shell 7 of this keeper 5.
This case is from the different places of general hot pressing die: general hot pressing die is typically with public affairs
Mould 3 upper, master mold 4 under mode work in coordination use, and this case be with male model 3 under,
Master mold 4 uses in upper configuration mode, therefore can be directed through being formed at the positioning of this male model 3
Portion 32, reach position this keeper 5 effect, just can in once hot-forming program,
This complex fiber material 6 is made to be combined to obtain this complex fiber material shell 7 with this keeper 5,
It is not required to carry out secondary operation program, reduce production process and its error amount that may accumulate.
