Description of the drawings
Using attached drawing, the utility model is described in further detail, but the embodiment in attached drawing is not formed to the utility model
Any restrictions.
Fig. 1 is a kind of structure diagram of stamping die of the utility model.
Specific embodiment
The utility model is further described with attached drawing with the following Examples：
A kind of stamping die, as shown in Figure 1, including upper mold 10 and with the corresponding lower mould part 30 in 10 position of upper mold, on
Mould 10 is provided with the punch 11 of evagination, and lower mould part 30 is included successively into setting up and down thick
Mould 40 and fine cut lower die 50 are cut, mould 40 is slightly cut and is provided with and 11 matched first die cavity 41 of punch, fine cut
Lower die 50 is provided with to be connected with 11 matched second die cavity 51 of punch, the first die cavity 41 with the second die cavity 51, the first die cavity 41
It is overlapped with the longitudinal axis center of the second die cavity 51, punch 11 is pressed into the first die cavity 41 and the second die cavity 51 successively.
The lower mould part 30 of the stamping die of the utility model includes slightly cutting mould 40 and fine cut into setting up and down successively
Lower die 50, the first die cavity 41 for slightly cutting mould 40 are connected with the second die cavity 51 of fine cut lower die 50.During punching press, punch 11 is pressed successively
Enter the first die cavity 41 and the second die cavity 51, i.e. embryo material disposably first passes through thick the first die cavity 41 for cutting mould 40 and slightly cut, again
After the second die cavity 51 by fine cut lower die 50 carries out fine cut, from the finished part of 50 bottom of fine cut lower die out.Due to this reality
Included slightly cutting mould 40 and fine cut lower die 50, and first into setting up and down successively with the lower mould part 30 of novel stamping die
The longitudinal axis center of 41 and second die cavity 51 of die cavity overlaps, simple in structure, and the thick of part can be completed in a procedure and is cut and smart
It cuts, only needs one-time positioning, do not need to reposition after thick cut, so the stamping die presswork rate height of the utility model,
Manufacturing procedure is simple, does not allow to be also easy to produce substandard products, and production cost is low.
Preferably, as shown in Figure 1,11 both sides of punch of upper mold 10 position upper mold 10 and lower mould part 30 when being provided with punching press
Guide post 20, slightly cut mould 40 be provided with 20 matched first positioning hole 42 of guide post, fine cut lower die 50 is provided with and guide post
20 matched second location holes 52, first positioning hole 42 are connected with the second location hole 52, and guide post 20 is sequentially inserted into the first positioning
42 and second location hole 52 of hole.When the punch 11 of upper mold 10 is pressed into the first die cavity 41 and the second die cavity 51, guide post 20 is inserted successively
Enter 42 and second location hole 52 of first positioning hole, positioning is played in guide post 20 and first positioning hole 42, the cooperation of the second location hole 52
The effect of upper mold 10 and lower mould part 30, prevents in punching course, 30 dystopy of upper mold 10 and lower mould part, to ensure stamping die
The stability of 30 relative position of upper mold 10 and lower mould part during tool punching press, and then ensure the yield rate of stamping products.
Preferably, as shown in Figure 1, the bore of 51 connectivity part of the first die cavity 41 and the second die cavity of fine cut lower die 50 is less than slightly
Cut the bore of 40 lower end of mould.Because fine cut is cut on the basis of thick cut, the first die cavity 41 of fine cut lower die 50 and the second mould
The bore of 51 connectivity part of chamber is less than the bore for slightly cutting 40 lower end of mould, i.e., fine cut lower die 50 is in the first die cavity 41 and the second die cavity 51
Protrusion cutting position 53 can be formed on the top of connectivity part, and when embryo material enters fine cut, the rim charge of embryo material can be kept under fine cut after fine cut
On the cutting position 53 that mould 50 protrudes, rim charge is not fallen out to the second die cavity 51, therefore is not in get stuck in punching course, is had
Fine cut is smoothed out conducive to fine cut lower die 50.
Preferably, as shown in Figure 1, the top of the second die cavity 51 is the cutting portion 54 that inner wall is through state, under
Portion is that inner wall is the horn-like discharge part 55 that upper bore is small, lower relative aperture is big.The cutting portion 54 of through state is to embryo material
Carry out fine cut, for that upper bore is small, lower relative aperture is big is horn-like, the inner wall of discharge part 55 has certain oblique for the inner wall of discharge part 55
Spend r so that rim charge and finished part after embryo material fine cut can be discharged smoothly, be not in get stuck.
Preferably, as shown in Figure 1, stamping die be additionally provided with positioning slightly cut mould 40 and the pin 70 of fine cut lower die 50,
Fine cut lower die 50 be provided with 70 matched third location hole 56 of pin, slightly cut mould 40 be provided with it is matched with pin 70
4th location hole 46, third location hole 56 are connected with the 4th location hole 46, and pin 70 is sequentially inserted into third location hole 56 and the 4th
Location hole 46.Pin 70 is sequentially inserted into 56 and the 4th location hole 46 of third location hole, i.e. pin 70 plays positioning and slightly cuts mould 40
It with the effect of fine cut lower die 50, can prevent in punching course, slightly cut mould 40 and fine cut lower die 50 since the effect of impulse force is produced
Raw dystopy.
Preferably, as shown in Figure 1, the top of upper mold 10 is provided with buffer plate 80.Buffer plate 80 is loaded on upper mold 10
Buffering after 10 punching press of upper mold cutting during return, is played the role of in top.
Finally it should be noted that above example is only to illustrate the technical solution of the utility model rather than to this reality
With the limitation of novel protected range, although being explained in detail with reference to preferred embodiment to the utility model, this field it is general
Lead to it will be appreciated by the skilled person that can be modified or replaced equivalently to the technical solution of the utility model, without departing from this
The spirit and scope of utility model technical solution.
