Description
Technical field
The present invention relates to technical field of mold, specially a kind of aluminium alloy stamping die with ejecting function.
Background technique
Punching press is to apply pressure to material using the mold being mounted on press machine, it is made to generate separation or plastic deformation,
To obtain a kind of pressure processing method of required part.Stamping die is essential components in punching course.It is existing
Punching press carries out punching press primarily directed to the harder material of the materials such as metal material, but with the increase to aluminum alloy materials demand,
It is essential to need to carry out punching press to aluminium alloy, but aluminium alloy quality is softer, it is easy to it deforms, it is de- in order to be easy
Mould can all be provided with liftout attachment on stamping die, part is ejected by liftout attachment, good in order to eject effect, ejection dress
It sets and multiple thimbles is generally set, ejected part by moving up and down for thimble.Due to aluminium alloy quality is softer, rushing
Part is pressed in lower die due to elevated pressures during pressure, aluminum alloy materials can be even pressed onto ejection through-hole sometimes, institute
With the damage in order to reduce part, need to reduce thimble quantity in the stamping die of aluminium alloy, but after reducing thimble quantity, it is right
Reduction is had in the jack-up effect of part.
As provided a kind of aluminium alloy stamping die liftout attachment in China Patent No. CN201720393413.X, pass through
Two horizontally movable plates are set at left and right sides of lower die, using the plug insertion part on plate and between mold core, from
And part is jacked up in the case where reducing thimble and not injuring part；But the device is still provided with thimble and top in lower die
Through-hole out, aluminium alloy, which still has to be pressed onto during punching press, to be ejected in through-hole；Still further aspect because thimble end compared with
Carefully, when ejecting part, can because stress and the too small reason of forced area can cause dent to piece surface, to influence zero
Part quality, so needing one kind for aluminium alloy stamping die in industry, to solve problems faced in industry.
Summary of the invention
The aluminium alloy stamping die with ejecting function that the purpose of the present invention is to provide a kind of, to solve existing pushing up
The problem of damage is caused to part is easy when the softer material of quality out.
To achieve the goals above, technical scheme is as follows:
A kind of aluminium alloy stamping die with ejecting function, including workbench, the suspension being installed on the workbench, setting
Hydraulic cylinder on suspension, the upper mold being connected on hydraulic cylinder, setting are on the table and lower die compatible with upper mold；
It is provided with the inner cavity communicated with lower die punching press bottom surface in the lower die, is used to support in the inner cavity equipped with liftout attachment
The load carrier of liftout attachment, the liftout attachment include the top plate slided in inner cavity, provide the Guiding machine of guiding for top plate
Structure and the driving mechanism for driving top plate to move along interior intracavitary vertical direction by guiding mechanism, the top plate are matched with load carrier
It closes.
As a further improvement of the present invention, the guiding mechanism includes symmetrical and being connected to top plate bottom two
Guide rod is correspondingly arranged on two secondary bars slided in the lumen on two guide rods, be connected between two guide rods with
The transverse slat that driving mechanism is slidably matched.
As a further improvement of the present invention, the transverse slat is provided with bar shaped groove, and the bar shaped groove and driving mechanism are sliding
Dynamic cooperation.
As a further improvement of the present invention, the driving mechanism includes the servo motor of installation in the lumen, described to watch
It takes motor coaxle and is connected with swing rod, the one end of the swing rod far from servo motor shaft connection place is slidably matched with guiding mechanism.
As a further improvement of the present invention, the load carrier be included lumenal levels sliding and with top plate cooperation
Loading plate, the loading plate are connected with the hydraulic cylinder on lower die lateral wall.
The beneficial effects of the present invention are:
The present invention solves in existing aluminium alloy punching course by the way that the top plate that can be moved up and down is arranged in lower die bottom
Since part is pressed in lower die by elevated pressures, need to be arranged excessive thimble, but thimble excessively causes part injury and top
The problem of very few ejection effect caused to part of through-hole reduces out；The configuration of the present invention is simple, maintenance easy to maintain, and operate letter
Single, cost is relatively low.

Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, tie below
The present invention will be described in detail for conjunction attached drawing and embodiment.
As shown in Figures 1 to 5, a kind of aluminium alloy stamping die with ejecting function, including workbench 1, it is mounted on work
Make the suspension 2 on platform 1, the hydraulic cylinder 3 being arranged on suspension 2, the upper mold 4 being connected on hydraulic cylinder 3, be arranged on workbench 1
And lower die 5 compatible with upper mold 4；
Be provided with the inner cavity 5a communicated with 5 punching press bottom surface of lower die in the lower die 5, be equipped in the inner cavity 5a liftout attachment with
And it is used to support the load carrier of liftout attachment, the purpose of the load carrier is that liftout attachment does not support in order to prevent, In
Huge pressure can damage liftout attachment when punching press, to influence stripping result；The liftout attachment is included in inner cavity
The top plate 6 that slides in 5a, the guiding mechanism that guiding is provided for top plate 6 and top plate 6 can be driven along inner cavity by guiding mechanism
The mobile driving mechanism of vertical direction in 5a, the top plate and load carrier cooperate.
As shown in Fig. 2, in order to preferably have guiding performance, the guiding mechanism includes that bilateral symmetry is distributed and is connected to top
Two guide rods 7 of 6 bottom of plate are correspondingly arranged on two secondary bars 71 that can be slided in the 5a of inner cavity on two guide rods 7.
As shown in Fig. 2, being connected with transverse slat 72 between two guide rods 7 in order to enhance its stability, being opened on the transverse slat 72
There is bar shaped groove 72a, is sliding combined with driving mechanism in the bar shaped groove 72a.
As shown in figure 3, symmetrical two guide chutes 5b is provided on the inner cavity 5a, it is corresponding in the guide chute 5b to slide
Two secondary bars 71 of dynamic cooperation.
As shown in Figure 1, the driving mechanism includes the servo motor 9 being mounted on the right side of the 5a of inner cavity, the servo motor 9 is left
Side is connected with swing rod 8, is provided with circular pegs 81, the circular pegs on the described one end of swing rod 8 far from 9 shaft connection place of servo motor
81 are slidably matched with bar shaped groove 72a.
As shown in Figure 1, being provided with the sliding slot 5c communicated with the right side wall of lower die 5, the load carrier packet in the inner cavity 5a
