Abstract
The utility model belongs to stamping die technology, it is related to a kind of arc backboard shaping mould for facilitating de- material, including upper die and lower die, the upper mold includes the cope plate of concave structure and the peripheral and liftable de- plate positioned at cope plate, the lower die includes surrounding the lower template of structure and the interior and liftable lower de- plate positioned at lower template, the lower de- plate is in the convex structure of cooperation cope plate structure, and the lower template is in the position close to lower de- edges of boards edge equipped with liftable several floating blocks.When this shaping mould is opened, the Web edges for encasing lower de- plate originally can be detached from, such worker could more easily remove the tablet of forming again by the top lift of floating block from lower de- plate.
Description
Technical field
The utility model relates to stamping die technology, in particular to a kind of arc backboard shaping mould for facilitating de- material.
Background technique
With the continuous improvement of industrial product quality, compared with other methods of machining and plastic processing, punching press adds
It is many unique no matter work all has the advantages that in technical aspect or economic aspect.It is mainly shown as:
1, the high production efficiency of punch process, and it is easy to operate, it is easy to accomplish mechanization and automation.
2, since mold ensure that the size and shape precision of punching press when punching press, and do not destroy the surface matter of stamping parts generally
Amount.
3, the processable size range out of punching press is larger, complex-shaped part.But mold one used in punch process
As there is specificity, sometimes one complex parts need several molds could machine-shapings, and the precision of mold manufacture is high, technology
It is required that it is high, it is technology-intensive product.
Liquid crystal display is mainly made of panel, backboard and control circuit etc., and backboard is subject to panel and control circuit
The Assembly part of important component part, backboard is more, and there are many structures such as notch, aperture, bent angle for backboard setting, to its essence
Degree requires very high.Backboard is sheet metal mostly, and since backboard is not simple pieces of sheet, it has certain radian, meanwhile,
Arcwall face is punched out, and the processes such as raising, because of the requirement of product cambered surface, common mold in process can the coefficient of resilience
Height, stress is big, and backboard can encase punch-pin when demolished, so that being difficult to de- material.
The utility model is to provide for the new mold of one kind just to solve the above problems.
Utility model content
The main purpose of the utility model is to provide a kind of arc backboard shaping moulds for facilitating de- material.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of arc backboard shaping mould facilitating de- material,
Including upper die and lower die, the upper mold includes the cope plate of concave structure and is located at cope plate periphery and liftable de- plate,
The lower die includes surrounding the lower template of structure and the interior and liftable lower de- plate positioned at lower template, and the lower de- plate is in match to close
The convex structure of formwork structure, the lower template are equipped with liftable several floating blocks in the position close to lower de- edges of boards edge.
Specifically, the upper de- plate lower end is equipped with locating piece, the lower template is equipped with locating slot, locating piece and locating slot
Between match.
Specifically, being equipped with raising punching in the lower template, the cope plate is equipped with jigger pin, raising punching and jigger pin
It matches.
By adopting the above technical scheme, the beneficial effect of technical solutions of the utility model is:
When this shaping mould is opened, the Web edges for encasing lower de- plate originally can be again by the top lift of floating block, under
It is detached from de- plate, such worker could more easily remove the tablet of forming.

Specific embodiment
The utility model is described in further detail combined with specific embodiments below.
Embodiment:
As depicted in figs. 1 and 2, a kind of arc backboard shaping mould of the utility model, including upper mold 1 and lower die 2, upper mold 1
Cope plate 11 and the peripheral and liftable de- plate 12 positioned at cope plate 11, lower die 2 including concave structure include surrounding structure
Lower template 21 and be located in lower template 21 and liftable lower de- plate 22, lower de- plate 22 in cooperation 11 structure of cope plate convex
Structure, lower template 21 are equipped with liftable several floating blocks 23 in the position close to lower de- 22 edge of plate.It is originally smooth when molding
Tablet 3 can form the structure of the downward turnup in edge under the action of cope plate 11 and lower de- plate 12.When die sinking, encase originally
The top lift that 3 edge of tablet of de- plate 22 can again by floating block 23 down is detached from from lower de- plate 22, and such worker could be relatively more square
Just the tablet 3 of forming is removed.
As shown in Figure 1, upper 12 lower end of de- plate is equipped with locating piece 14, lower template 21 is equipped with locating slot 211,14 He of locating piece
It is matched between locating slot 211.When molding, locating piece 14 can be penetrated in locating slot 211, keep de- plate 12 and lower template 21 accurate
Positioning, such cope plate 11 can be also accurately positioned with lower de- plate 22, guarantee 3 formed precision of tablet.
As shown in Figure 1, being equipped with raising punching 24 in lower template 21, cope plate 11 is equipped with jigger pin 13, and raising rushes 24 Hes
Jigger pin 13 matches.Raising punching 24 is used to form the bulge-structure on tablet 3, and jigger pin 13 then pushes up bulge-structure rear
Firmly, guarantee to stretch to complete.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to practical
Novel protection scope.
