Material 61 and by the cavity of its air-pressure forming 15；High pressure air flue 16 is offered in the top mold frame 11；The high pressure air flue 16 and institute
State the connection of cavity 15.By being equipped with cavity 15 in the first lower mold core 14 of air-pressure forming mold, height is equipped in top mold frame 11
It calms the anger and 16 and is connected to the cavity 15.Wherein, the high pressure air flue 16 can be (not shown) even with external pneumatic compression devices
It connects, the raw material sheet material 61 of softening is squeezed into cavity 15 with to inject high pressure gas and be molded.Because the molding of raw material sheet material 61 be with
High pressure gas drives, rather than it is traditional driven with mechanical force, advantage is that gas pressure is adjustable, and uniform force.
The sheet material workpiece processed in this way, surface smoothness is very good, and puts be not easy to moulding rebound long, meanwhile, use warp
Mobile phone shell is made in the 3D sheet materials 62 of air-pressure forming, can also substantially reduce the deflection of manufactured goods.
As shown in figure 4, causing to avoid the high pressure gas sprayed from the outlet of high pressure air flue 16 from directly impacting raw material sheet material 61
It is damaged, and the top mold frame 11 is equipped with the groove 17 coordinated with cavity 15 close to the one side of lower mold holder 12, pacifies in the groove 17
Equipped with the first upper mold core 13 for shunt gas；If first upper mold core 13 is equipped with dry gas close to the side of high pressure air flue 16
Slot 131；The high pressure air flue 16 is connected to by air drain 131, groove 17 with cavity 16.By the way that multiple air drains 131 are arranged, ensureing
The impact force of high pressure gas is also reduced while air pressure abundance.
With continued reference to Fig. 2,4, first upper mold core 13 is plane close to the one side of the first lower mold core 14.There is no due to
Upper and lower mold core has to mutually agree with and there are the demands at molding angle, it is possible to which sheet material, which is made side, the shape of reversed draft
Shape, therefore, the madial wall of the cavity 15 is the cambered surface with back-off position.
Further, for ease of in molding the top mold frame 11 be preferably directed at lower mold holder 12, the top mold frame 11 is set
There is guide post 21, guide pillar hole 21 is offered on the lower mold holder 12；The guide post 21 and the guide pillar hole 22 are coaxially connected.
As shown in figures 5-9, the present utility model application also provides a kind of punching system.The punching system is related to material piece
61 high-pressure molding of material and 3D sheet materials 62 are cut.In the present embodiment, the punching system includes above-mentioned air-pressure forming mould
Tool, further includes the die cutting die for being cut to the 3D sheet materials 62 after air-pressure forming；The die cutting die includes upper die holder
31, the second upper mold core 32, lower die holder 33, the second lower mold core 34 and punching component 4；Second upper mold core 32 is arranged on described
31 lower section of die holder, second lower mold core 34 are arranged in 33 upper surface of the lower die holder；Under second upper mold core 32 and second
The die cavity for housing 3D sheet materials 62 to be cut is formed between mold core 34；Punching component 4 is slidably arranged in second lower die
34 surrounding of core.
In the present embodiment, the die cutting die includes the punching component 4 of four groups of energy lateral movements, to be punched 3D pieces
The side edge shape of material 62 and lateral aperture position, the second upper mold core 32 and the second lower mold core 34 are no longer punching working faces, and have only been
To the effect of fixed semi-finished products sheet material 62.
As shown in Figure 10,11, each punching component 4 includes power seat 41, link block 42 and punching tool 43；It is described
Power seat 41 is installed in 33 upper surface of the lower die holder and the link block 42 is driven to carry out expanding-contracting action；The link block 42 1
End connects the power seat 41, and the other end connects the punching tool 43；The punching tool 43 is slidably arranged in lower die holder 33
Boring cutter upper and equipped with the profile cutter head 431 to match with 62 profile of 3D sheet materials and for the lateral opening hole in 3D sheet materials 62
First 432.The trimming working face of second lower mold core 34 is equipped with and the position lateral incision of 43 matched hole of the punching tool.Such as Figure 12
Shown, the extra rim charge in 62 side of 3D sheet materials has been removed, the Kong Weiru volumes key position hole of side, screen locking keyhole, charging hole etc.
Also it opens and cuts out.
More preferably, to avoid in clamping process, the upper die holder 31 and lower die holder 33 carry out rigid contact, the punching
Mold is additionally provided with bolster 5；The bolster 5 is compressed spring；Described compressed spring one end against second upper mold core 32,
The other end is against upper die holder 31.
By using the punching system, not only flatness is good, is not easy plasticity rebound for the 3D sheet materials 62 of output, or even can side
Face trepanning and it is enough to coat the reversed draft region of mobile phone shell side.Certainly, two molds in punching system must match
Conjunction, which is used together, can be only achieved expected effect.
It should be understood that above example is only to illustrate the technical solution of the utility model, it is rather than its limitations, right
For those skilled in the art, it can modify to technical solution described in the above embodiment, or to which part skill
