Description
Technical field
The utility model belongs to technical field of mold, more particularly to a kind of stamping die negative angle bending structure.
Background technique
It is very frequent that product bending and molding appears in hardware mould, some angles of product require very high, and material thickness has difference
Product surface has the high product of plucking phenomenon angle requirement and is unable to reach after causing bending angle to change the straight bending of weight after different
It is required that production not can guarantee bending angle stability.The conventional downward bending the case where, it is desirable to which the product of bending negative angle is normal
Downward bending mechanism can only be 90 degree of bending, the bending of Yao Shixian negative angle can not achieve, even lower die enter block mill negative angle, on
The not anti-shape of stamping head, the angle of bending is also unstable after mold is closed.
Utility model content
In view of the deficienciess of the prior art, to provide a kind of stamping die negative for technical problem to be solved in the utility model
Angle bending structure, can a bending in place, guarantee bending angle it is qualified, without plucking phenomenon, product is stable, high production efficiency.
In order to solve the above technical problems, technical solution adopted in the utility model is: a kind of stamping die negative angle bending
Structure, including upper die component and lower mold assemblies are equipped with de- material component between the upper die component and lower mold assemblies；The upper mold group
Part includes upper die holder, and the upper die holder bottom is equipped with upper padding plate, and the upper padding plate bottom is equipped with upper clamp plate；The lower mold assemblies packet
Lower die holder is included, lower bolster is equipped at the top of the lower die holder, is equipped with lower template at the top of the lower bolster；The de- material component includes only
Baffle, the baffle plate bottom are equipped with upper de- plate；The upper die component is equipped with formed punch, and the lower mold assemblies are equipped with foldable component,
The foldable component includes shaping angled-lift splits and enters block, the shaping angled-lift splits with the lower die shaping of shaping angled-lift splits cooperation
Enter block bottom with lower die shaping and be equipped with reset mandril, the reset mandril bottom is equipped with reset spring.
Above-mentioned stamping die negative angle bending structure, the formed punch are mounted on upper clamp plate, and the shaping angled-lift splits are under
Mould shaping enters block in the cavity of lower template, and the reset mandril is set in lower bolster, and the reset spring is set to lower die holder
In.
Above-mentioned stamping die negative angle bending structure, the cavity are in inverted trapezoidal structure, the shaping angled-lift splits and lower die
Shaping adapts to cavity after entering block combination.
Above-mentioned stamping die negative angle bending structure, the shaping angled-lift splits height are greater than lower die shaping and enter block height.
The advantages of the utility model stamping die negative angle bending structure, is:
1, the utility model stamping die negative angle bending structure can improve bending angle using negative angle bending structure
Stability reduces the maintenance of mold, improves production production capacity；When the rebound of product bending angle is unable to reach greatly, by using negative angle
Bending structure may be implemented；Bending vertically downward can be reduced, and to destroy this mechanism to the scratch of product surface easy to process, is conducive to adjust
Die repair mould；Product shaping is stablized, and production capacity and product quality are promoted.
2, the utility model stamping die negative angle bending structure, using bending negative angle shaping mechanism, can from flank movement,
Shaping angled-lift splits can enter block with lower die shaping and be closed completely the stability that can improve bending angle with negative angle bending, and mold is opened
Shaping angled-lift splits and lower die shaping enter block all and are that will not be deformed from flank movement angles of product because of de- material power will not when mould
There is plucking phenomenon to product surface, negative angle bending mechanism promotes the stability of mould bending, reduces maintenance, improves production effect
Rate.
Detailed description of the invention
Fig. 1 is the utility model mold Unclosing structure schematic diagram；
Fig. 2 is the utility model mold closing structure schematic diagram.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
Embodiment 1, a kind of as shown in Figure 1, 2, stamping die negative angle bending structure, including upper die component and lower mold assemblies,
De- material component is equipped between the upper die component and lower mold assemblies；The upper die component includes upper die holder 1,1 bottom of upper die holder
Portion is equipped with upper padding plate 2, and 2 bottom of upper padding plate is equipped with upper clamp plate 3；The lower mold assemblies include lower die holder 8, the lower die holder 8
Top is equipped with lower bolster 7, is equipped with lower template 6 at the top of the lower bolster 7；The de- material component includes baffle plate 4, the baffle plate
4 bottoms are equipped with upper de- plate 5；The upper die component is equipped with formed punch 9, and the lower mold assemblies are equipped with foldable component, the foldable component
Enter block 11 including shaping angled-lift splits 10 and the lower die shaping cooperated with shaping angled-lift splits 10, the shaping angled-lift splits 10 are under
Mould shaping enters 11 bottom of block and is equipped with reset mandril 12, and 12 bottom of reset mandril is equipped with reset spring 13.
The formed punch 9 is mounted on upper clamp plate 3, and the shaping angled-lift splits 10 enter block 11 set on lower template 6 with lower die shaping
Cavity 61 in, the reset mandril 12 be set to lower bolster 7 in, the reset spring 13 be set to lower die holder 8 in.
The cavity 61 is in inverted trapezoidal structure, and the shaping angled-lift splits 10 enter after block 11 combines with lower die shaping to be adapted to hold
Chamber 61.
10 height of shaping angled-lift splits is greater than lower die shaping and enters 11 height of block.
Guide post guide die moves downward, and upper de- plate 5 first pushes down material, and upper de- plate 5, which moves downward, pushes lower die shaping to enter
Block 11 moves, and upper mold reforming plunger 9 contacts shaping angled-lift splits 10, continues to push shaping angled-lift splits 10 when movement downwards, mold is complete
After complete closure, shaping angled-lift splits 10 shift position onto and lower die shaping enters 11 closed pair product bending of block and carries out negative angle shaping.Mold is opened
After mould, reset spring 13 pushes reset mandril 12 that shaping angled-lift splits 10, lower die shaping are entered block 11 and opens reset, and product buoyance lift is de-
It opens.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the specific implementation of the utility model is not
It is limited by above embodiment.Those skilled in the art can be under the premise of without departing from the utility model technical concept, to this
Various modification can be adapted or modification for utility model, these modifications or modification are also fallen within the protection scope of the utility model certainly.
