Chamber is provided with punch die back seat, and the bottom of the punch die back seat, which is provided with, rushes stick, and the bottom end for rushing stick sequentially passes through upper die holder
The bottom at the top at top and push plate, the push plate is provided with and rushes the ejector sleeve that stick matches, the bottom left and right sides of the push plate
It is provided with gag lever post, and the top of gag lever post is fixedly connected through push plate with the bottom of upper die holder, the top of the lower die holder
It is provided with the limit hole to match with gag lever post, the top center of the lower die holder is provided with cavity plate, is provided with product in cavity plate.
Further, four groups of slide openings to match with mandril are provided at the top of the punch die back seat.
Further, the height of the punch die back seat be punch die after pad and punch die back seat bottom between distance two/
One.
Further, the depth of the limit hole is greater than the length that gag lever post stretches out push plate.
Further, the diameter of the punch die back seat is identical as upper die holder intracavity diameter.
Further, the outer wall of the punch die back seat is provided with sliding block, and the inner wall of the upper die holder is provided with and sliding block phase
Matched sliding slot.
Compared with prior art, the utility model has the beneficial effects that the utility model when product complete punch when, with top
Bar pushes push plate to head on ejector sleeve, and ejector sleeve again ejects product, while being declined upper die holder to production by gag lever post and limit hole
It is limited when product are punched, ensure that punch position will not deviate, while rushing stick to do short, reduction flexible deformation, increasing
Add product concentricity, makes to adapt to that wide, stock utilization is high, productivity is higher, lower production costs.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
In figure: 1, upper die holder；2, lower die holder；3, it is padded after punch die；4, mandril；5, push plate；6, fixed screw；7, after punch die
Seat；8, stick is rushed；9, ejector sleeve；10, gag lever post；11, limit hole；12, product.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, the utility model provides a kind of technical solution: a kind of plate pushing structure, including upper die holder 1 and lower die holder
2, pad 3 after punch die is provided at the top of the inner cavity of upper die holder 1, and the bottom of pad 3 is provided with four groups of mandrils 4 after punch die, upper die holder 1
Bottom is provided with push plate 5, and push plate 5 is connect by fixed screw 6 with the bottom of mandril 4, after the inner cavity of upper die holder 1 is provided with punch die
Seat 7, the bottom of punch die back seat 7, which is provided with, rushes stick 8, and the bottom end for rushing stick 8 sequentially passes through the top of upper die holder 1 and the top of push plate 5,
The bottom of push plate 5 is provided with and rushes the ejector sleeve 9 that stick 8 matches, and the bottom left and right sides of push plate 5 is provided with gag lever post 10, and limits
The top of position bar 10 is fixedly connected through push plate 5 with the bottom of upper die holder 1, and the top of lower die holder 2 is provided with and 10 phase of gag lever post
Matched limit hole 11, the top center of lower die holder 2 are provided with cavity plate, product 12 are provided in cavity plate.
As shown in Figure 1, the top of punch die back seat 7 is provided with four groups of slide openings to match with mandril 4, make mandril 4 and punch die
Back seat 7 is independent of each other when moving up and down；
As shown in Figure 1, the height of punch die back seat 7 be after punch die between 7 bottom of pad 3 and punch die back seat distance two/
One, make punch die back seat 7 when rising, mandril 4 there can be enough spaces to push push plate 5, and push plate 5 is made to make product by ejector sleeve 9
It is detached from stick 8 is rushed；
As shown in Figure 1, the depth of limit hole 11 is greater than the length that gag lever post 10 stretches out push plate 5, prevent gag lever post 10 from reaching
When 11 bottom of limit hole, rushes stick 8 and punch die is not completed to product；
As shown in Figure 1, the diameter of punch die back seat 7 is identical as 1 intracavity diameter of upper die holder, make to rush stick 8 when moving up and down not
It will appear positional shift, improve the accuracy of punching；
As shown in Figure 1, the outer wall of punch die back seat 7 is provided with sliding block, the inner wall of upper die holder 1 is provided with to match with sliding block
Sliding slot, preventing punch die back seat 7 from generating positional shift causes mandril 4 larger with the appearance of the slide opening of punch die back seat 7 during decline
Frictional force.
Embodiment: after rushing the completion punching of stick 8, punch die back seat 7 starts to move upwards, under the promotion of formpiston mandril, punching
