Description
Technical field
The utility model is related to processing mold field, more particularly to a kind of high-accuracy blanking die.
Background technology
In processing, common punching etc. is clean steel piece, can be processed using conventional processing mold,
And the high-precision material strip used in certain fields generally by the multilayers such as positive PF films, PSA glue, SUS and reverse side PF films into being grouped as,
When processing the material strip, there is high requirement with consistent to the precision of the knife edge clearance of mold, if required requirement is unable to reach,
Often there is gap deviation, the abnormal conditions such as excessive glue, white edge, lousiness, glue laminated wound and bubble occur so as to cause product.So
The structure of conventional processing mold is difficult to the punching press demand for meeting high-precision product, and product qualification rate is not often high.
Utility model content
To solve the above problems, the utility model provides a kind of high-accuracy blanking die.
One side according to the present utility model provides a kind of high-accuracy blanking die, including upper mold portion, lower mold portion and
Part, the part are mounted on the centre of the upper mold portion and the lower mold portion；The upper mold portion is equipped with cutter, the cutter
Positioned at the top of the part；Wherein, the part is equipped with multiple dowel holes and multiple pin holes, is equipped on the dowel hole
Guide post is processed, positioning pin is fixed on the pin hole.
On the one hand high-accuracy blanking die in the utility model can reduce the multiple accumulated error of part work in-process, carry
On the other hand the overall precision of high mould parts, can be in close contact with material strip in punching press, effectively product be avoided hair occur
The abnormal conditions such as silk, bubble improve the production yield of product, reduce production cost.
In some embodiments, the upper mold portion is divided into upper mold seat, upper padding plate and upper clamp plate from top to bottom, described
Lower mold portion is divided into die holder, lower bolster and lower template from top to bottom.Thereby, it is possible to set the concrete structure of mold.
In some embodiments, the top of the lower mold portion is equipped with stripper plate.Thereby, it is possible to be used for binder de- material.
In some embodiments, multiple dowel holes are separately positioned on each angle of the part, each guide sleeve
Two processing guide posts are mounted on hole.Thereby, it is possible to set distribution of the dowel hole on part.
In some embodiments, multiple pin holes are distributed in the centre on each side of the part.Thereby, it is possible to set
Distribution of the pin hole on part.
In some embodiments, it is made of on the inside of the edge of a knife of the cutter soft binder, on the inside of the edge of a knife of the cutter
Equipped with little spring.Thereby, it is possible to make to be in close contact in punching press with part on the inside of the edge of a knife of cutter, avoid product occur lousiness,
The abnormal conditions such as bubble.
Description of the drawings
Fig. 1 covers figure for a kind of high-accuracy blanking die of one embodiment of the utility model；
Fig. 2 is the structure chart of the part of high-accuracy blanking die shown in Fig. 1.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 schematically shows a kind of a kind of high-accuracy blanking die of embodiment according to the present utility model.Such as
Shown in Fig. 1, which includes a upper mold portion 1 and a lower mold portion 2, and there are one zero for the intermediate installation of upper mold portion 1 and lower mold portion 2
Part 3.Wherein, upper mold portion 1 is divided into upper mold seat, upper padding plate and upper clamp plate from top to bottom, and lower mold portion 2 is divided into from top to bottom
Die holder, lower bolster and lower template, the top of lower mold portion 2 are equipped with stripper plate 4, and after mounting, bottom setting is located at lower die to part 3
The top in portion 2, and through stripper plate 4.Further, it is also possible to other processing plates are arranged as required to, such as in the lower section of upper mold portion 1
De- backboard of setting etc..
Upper mold portion 1 is equipped with cutter 11, and cutter 11 is specifically mounted on upper mold seat, and the edge of a knife of bottom is located at part 3
Top and can be used in process part 3.Soft binder is used on the inside of the edge of a knife of cutter 11, and equipped with little spring.Wherein, part
3 are fixed by more processing guide posts 33 and Duo Gen positioning pins 34.
Fig. 2 shows the part of high-accuracy blanking die shown in Fig. 1.As shown in Fig. 2, part 3 is substantially square, Qi Gejiao
On be all provided with there are one dowel hole 31, the inner guiding post guide sleeve of micron order can be set in dowel hole 31, and the centre on each side of part 3
Pin hole 32 is then equipped with, multiple pin holes 32 can also be uniformly arranged on longer side.When being processed to part 3, exist respectively
Installation processing guide post 33 on each dowel hole 31, and positioning pin 34 is installed to be processed fixation to part 3 on each pin hole 32.This
Outside, to facilitate installation, two shorter processing guide posts 33 can also respectively be installed on each dowel hole 31 from upper and lower ends.
In the blanking die in using the utility model, due to having used processing guide post 33 and positioning pin on part 3
34 are fixed so that and all 3 lines of part cut the locating element 3 of processing and guide elements 3 and can process at one time, so as to
More than 3 processing accumulated error of part is enough reduced, 3 overall precision of mould parts is improved, processing is cut using ultrahigh precision line in part 3
When ensure mold overall precision, and can realize precision positioning encapsulating.
