Abstract
The anti-blocking structure of the small-hole female die comprises a female die base, wherein an installation through hole is processed in the female die base, and a punching female die gasket are sequentially sleeved in the installation through hole; the bottom of the concave die holder is provided with a sealing plate through a screw; a punching die hole is processed at the center of the punching female die, a blanking hole is processed at the center of a gasket of the punching female die, and an avoidance port is processed on the sealing plate; the punching die hole and the blanking hole are coaxially arranged; the avoiding opening is positioned below the blanking hole. Compared with the prior art, the anti-blocking structure of the small-hole female die of the utility model has the advantages that the punching die holes are arranged in the punching female die, the blanking holes are arranged in the punching female die gasket, the punched waste can smoothly leak and is not easy to accumulate because the aperture of the blanking holes is larger than that of the punching die holes, and the punching female die gasket are processed in a segmented manner, so that the processing difficulty and the processing cost are reduced; the service condition of the female die and the male die is well guaranteed by the structure, and the risk of part damage is reduced.
Description
Technical Field
The utility model relates to the technical field of mold, specifically indicate a stifled material structure is prevented to aperture die.
Background
In the die structure, a punching female die with an integral structure is generally arranged in a female die base, and the punching female die needs to be improved because small-sized punching waste materials are small in size and light in weight and are extremely easy to turn and accumulate in the female die, so that the waste materials are not smooth in leakage, and finally the female die is cracked and broken.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is not enough to above-mentioned prior art, and provide a stifled material structure is prevented to aperture die.
In order to solve the technical problem, the utility model discloses a technical scheme is:
the anti-blocking structure of the small-hole female die comprises a female die base, wherein an installation through hole is processed in the female die base, and a punching female die gasket are sequentially sleeved in the installation through hole; the bottom of the concave die holder is provided with a sealing plate through a screw; a punching die hole is processed at the center of the punching female die, a blanking hole is processed at the center of a gasket of the punching female die, and an avoidance port is processed on the sealing plate; the punching die hole and the blanking hole are coaxially arranged; the avoiding opening is positioned below the blanking hole.
Further, the height of the die holder is 25mm, the height of the punching die is 12mm, and the height of the punching die gasket is 13 mm.
Further, the diameter of the orifice of the die hole is 1.2mm, and the inner wall of the die hole is provided with a single side with an inclination of 0.13 degrees; the diameter of the orifice of the blanking hole is 4mm, and the inner wall of the blanking hole is provided with a single-side inclination of 0.5 degrees.
Furthermore, the avoiding opening is a round hole, and the diameter of the avoiding opening is 8 mm.
Compared with the prior art, the anti-blocking structure of the small-hole female die of the utility model has the advantages that the punching die holes are arranged in the punching female die, the blanking holes are arranged in the punching female die gasket, the punched waste can smoothly leak and is not easy to accumulate because the aperture of the blanking holes is larger than that of the punching die holes, and the punching female die gasket are processed in a segmented manner, so that the processing difficulty and the processing cost are reduced; the service condition of the female die and the male die is well guaranteed by the structure, and the risk of part damage is reduced.

Fig. 1 is a schematic structural diagram of the present invention;
the punching die comprises a die holder 1, a die seat 2, a punching die 3, a punching die gasket 4, a sealing plate 5, a die hole 6, a blanking hole 7 and an avoiding opening.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below.
As shown in fig. 1, the anti-blocking structure of the small-hole female die comprises a female die holder 1, wherein an installation through hole is processed in the female die holder 1, and a punching female die 2 and a punching female die gasket 3 are sequentially sleeved in the installation through hole; the bottom of the concave die holder 2 is provided with a sealing plate 4 through a screw; a die hole 5 is formed in the center of the punching female die 2, a blanking hole 6 is formed in the center of the punching female die gasket 3, and an avoidance opening 7 is formed in the sealing plate 4; the punching die hole 5 and the blanking hole 6 are coaxially arranged; the avoiding opening 7 is positioned below the blanking hole 6.
In the embodiment, the height of the die holder 1 is 25mm, the height of the punching die 2 is 12mm, and the height of the punching die gasket 3 is 13 mm; the diameter of the orifice of the die hole 5 is 1.2mm, and the inner wall of the die hole 5 is provided with a single-side inclination of 0.13 degrees; the diameter of the orifice of the blanking hole 6 is 4mm, and the inner wall of the blanking hole 6 is provided with a single-side inclination of 0.5 degrees; the avoiding opening 7 is a round hole, and the diameter of the avoiding opening 7 is 8 mm.
The utility model discloses in, the die in the die holder 1 falls into die 2 and the die packing ring 3 that punches a hole of punching a hole to punch a hole 5 and blanking hole 6 of punching a hole respectively in die 2 and the die packing ring 3 that punches a hole, adopt segmentation processing to reduce the processing degree of difficulty and processing cost, die hole 5 after shortening moreover makes the waste material can neatly leak down, do not take place the upset downthehole, unfavorable condition such as pile up, set up the blanking hole 6 that is greater than die hole 5 in die packing ring 3 that punches a hole simultaneously, make the waste material can the unhindered quick hourglass down.
The present invention is not limited to the above-described embodiments, and those skilled in the art can make modifications or changes without departing from the spirit of the present invention.
