Destruction problem to part after stretching.
The technical solution of the utility model is：A kind of stretching die part delay demolding mechanism, including upper mould and die, it is described
Die is bolted on below mould, and mould is fixedly arranged above nitrogen cylinder, the driving of the upper nitrogen cylinder on described
End is connected with material pressing core straight down, is provided with lower blank holder, sets below the lower blank holder below the die
Lower nitrogen cylinder is equipped with, mould emptier is set in the top of the lower blank holder, the mould emptier includes being fixed on lower blank holder
On push-and-pull cylinder, the outfan of the push-and-pull cylinder is connected with embedded block, and the embedded block is by being fixed on lower blank holder
Bottom guide and cover plate be embedded in the middle of material pressing core and lower blank holder.
Further, the embedded block is square block, and little inclined-plane is provided with above the built-in end of the embedded block.
Further, above the embedded block, little bevel angle is 30 to 45 °.
Further, the embedded block is threadedly coupled with push-and-pull cylinder.
Further, upper guide plate is additionally provided with above the embedded block.
Further, when the upper mould reaches bottom dead centre, the embedded block is embedded into pressure under the promotion of push-and-pull cylinder
In the middle of material core and lower blank holder.
Further, when the upper mould reaches bottom dead centre, the embedded block is retreated to initially next time in the pulling of push-and-pull cylinder
Position.
This utility model has the advantages and positive effects that：This utility model is used for replacing traditional lathe time delay and nitrogen
Cylinder system time delay, solves the problems such as traditional approach range of application is narrow, and manufacturing cost is high, debugging difficulty is big.This structure letter
Single, installation and debugging are convenient, with low cost, and reliability is high, effectively ensure mould production cycle and quality, reduce manufacturing cost.

Specific embodiment
Below in conjunction with the accompanying drawings this utility model is elaborated.
The problem that this utility model is solved is, when upper mould 1 and die 2 are up moved under the drive of lathe top shoe, under
Blank holder 5 is moved under the promotion of lower nitrogen cylinder 6 upwards, and at this moment as upper material pressing core 4 is further pressed against on part, lower blank holder 5 will
Meeting causes shape deterioration upwards to the part for completing stretching.
As shown in Fig. 1-Fig. 3 structural representations of the present utility model, this utility model provides a kind of stretching die part to postpone
Mould emptier, including upper mould 1 and die 2, the die 2 are bolted on below mould 1, the top of mould 1 on described
Nitrogen cylinder 3 is fixed with, the drive end of the upper nitrogen cylinder 3 is connected with material pressing core 4 straight down, under the die 2
Side is provided with lower blank holder 5, and the lower section of the lower blank holder 5 is provided with lower nitrogen cylinder 6, sets in the top of the lower blank holder 5
Mould emptier is put, the mould emptier includes the push-and-pull cylinder 7 being fixed on lower blank holder 5, the outfan of the push-and-pull cylinder 7
It is connected with embedded block 8, the embedded block 8 is embedded into upper material pressing core by the bottom guide 9 that is fixed on lower blank holder 5 and cover plate 10
4 and lower blank holder 5 in the middle of.
The embedded block 8 is square block, and little inclined-plane is provided with above the built-in end of the embedded block 8.On the embedded block 8
The little bevel angle in side is 30 to 45 °.The embedded block 8 is threadedly coupled with push-and-pull cylinder 7.It is additionally provided with above the embedded block 8
Upper guide plate 11.
When the upper mould 1 reaches bottom dead centre, the embedded block 8 is embedded into material pressing core 4 under the promotion of push-and-pull cylinder 7
In the middle of lower blank holder 5.When the upper mould 1 reaches bottom dead centre, the embedded block 8 is retreated to next time in the pulling of push-and-pull cylinder 7
Initial position.
The course of work of this example：This utility model provide stretching die part delay demolding mechanism when in use, when upper
When mould 1 and upper material pressing core 4 are down moved and plate is contacted, the embedded block 8 of mould emptier is in initial position；When upper mould 1 completes to draw
When reaching up to bottom dead centre, the push-and-pull cylinder 7 of mould emptier promotes embedded block 8, and embedded block 8 is pushed lower blank holder 5 and upper binder
Fill in space between core 4, when so blank holder 5 is up moved instantly, due to the presence of embedded block 8 for newly pushing, push
Embedded block 8 and upper material pressing core 4 are promoted and are moved upwards by flange 5 together, it is possible to achieve the steady rising of stretched parts and do not produce
Damaged deformation, finally, when upper mould 1 reaches top dead-centre, the push-and-pull cylinder 7 of mould emptier pulls embedded block 8 to return back to initial bit
Put.Complete an actuation cycle.
This utility model is used for replacing traditional lathe time delay and nitrogen cylinder delayed time system, solves traditional approach application model
Enclose narrow, manufacturing cost is high, the problems such as debugging difficulty is big.This simple structure, installation and debugging are convenient, with low cost, and reliability is high,
Effectively ensure mould production cycle and quality, reduce manufacturing cost.
