Abstract
The utility model discloses a die structure for punching a small hole. The die structure for punching the small hole comprises an upper die holder, an upper cushion plate, an upper clamp plate, a stop baffle and an upper separating plate, which are arranged in sequence; the upper die holder and the upper gasket plate as well as the upper cushion plate and the upper clamp plate are respectively fixedly connected; the stop baffle and the upper separating plate are fixedly connected, are movably sleeved outside the lower end of an ejector rod and can move up and down along the axis of the ejector rod; the upper end of the ejector rod is abutted against the lower end of a reset spring; the upper end of the reset spring is abutted against the upper die holder; a punch is fixed in the upper clamp plate; the punch respectively penetrates through the interior of each of the stop baffle and the upper separating plate. The die structure for punching the small hole adopts a two-section structure, so the strength of the punch is enhanced; the damage probability of the punch is reduced, two separating-in blocks are arranged by corresponding to the punch and can perform dual-layer guide actions on the punch, so the risk that the punch is broken is further reduced and the service life of the punch is prolonged.
Description
Technical field
The utility model relates to a kind of mould structure, relates in particular to one and rushes aperture mould structure.
Background technology
In Mould Machining, often need to process the small structures such as pore, micropore to product.The general employing with small aperture drift of the same size of existing mould structure carried out punching, adopt the stripper plate mating with this punching external diameter to carry out the demoulding simultaneously, but when aperture external diameter hour, needed drift external diameter is very little too, this reduces with regard to the stress that makes drift, when drift is movable in stripper plate, be easy to impaired or fracture, reduce drift service life.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides one to rush aperture mould structure, when rushing aperture, also can effectively protect drift injury-free.
The utility model for the technical scheme that solves its technical problem and adopt is: one is rushed aperture mould structure, comprise the upper bolster setting gradually, upper padding plate, train wheel bridge, stop plate and upper de-plate, upper bolster is fixedly connected with respectively with train wheel bridge with upper padding plate and upper padding plate, stop plate is fixedly connected with upper de-plate, this stop plate and upper de-plate are movably set in outside push rod lower end and can move up and down along this push rod axis, the upper end of this push rod pushes against the lower end of returning spring, the upper end of this returning spring pushes against upper bolster, in described train wheel bridge, be fixed with drift, this drift is set in respectively in described stop plate and upper de-plate, the external diameter of described nose of punch is consistent with aperture external diameter to be rushed, the external diameter of this ram bottom is greater than the external diameter of its end, to should drift position being provided with successively from top to bottom first, taking off into piece and second and take off into piece in described de-plate, described drift is set in successively this and first takes off piece and second and take off in the drift accommodating hole in piece, and first to take off drift accommodating hole external diameter in piece consistent with the external diameter of described ram bottom for this, this second take off into the external diameter of drift accommodating hole and the external diameter of described nose of punch of piece consistent.
As further improvement of the utility model, described drift is set in the drift accommodating hole in described stop plate, and it is consistent that the drift accommodating hole external diameter in this stop plate is greater than described ram bottom external diameter.
As further improvement of the utility model, between described upper bolster and upper padding plate and upper padding plate and train wheel bridge, by screw, be connected respectively.
As further improvement of the utility model, between described stop plate and upper de-plate, by screw, be connected.
The beneficial effects of the utility model are: this drift that rushes aperture mould structure adopts two-part structure, not only can strengthen the intensity of drift, reduce its impaired probability, and corresponding drift is provided with two and takes off into piece, these two take off into piece and can play double-deck guide effect to drift again, further reduce the risk that drift is fractureed, promote drift service life.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
By reference to the accompanying drawings, make the following instructions:
1---upper bolster 2---upper padding plate
3---train wheel bridge 4---stop plate
5---above de-plate 6---drift
Second takes off into piece 7---first takes off into piece 8---
9---push rod 10---returning spring
The specific embodiment
By reference to the accompanying drawings; the utility model is elaborated; but protection domain of the present utility model is not limited to following embodiment, the simple equivalence of in every case being done with the utility model claim and description changes and modifies, within all still belonging to the utility model patent covering scope.
As shown in Figure 1, one is rushed aperture mould structure, comprise the upper bolster 1 setting gradually, upper padding plate 2, train wheel bridge 3, stop plate 4 and upper de-plate 5, upper bolster is fixedly connected with respectively with train wheel bridge with upper padding plate and upper padding plate, , stop plate is fixedly connected with upper de-plate, this stop plate and upper de-plate are movably set in outside push rod 9 lower ends and can move up and down along this push rod axis, the upper end of this push rod pushes against the lower end of returning spring 10, the upper end of this returning spring pushes against upper bolster, in described train wheel bridge, be fixed with drift 6, this drift is set in respectively in described stop plate and upper de-plate, it is characterized in that: the external diameter of described nose of punch is consistent with aperture external diameter to be rushed, the external diameter of this ram bottom is greater than the external diameter of its end, to should drift position being provided with successively from top to bottom first, taking off into piece 7 and second and take off into piece 8 in described de-plate, described drift is set in successively this and first takes off piece and second and take off in the drift accommodating hole in piece, and first to take off drift accommodating hole external diameter in piece consistent with the external diameter of described ram bottom for this, this second take off into the external diameter of drift accommodating hole and the external diameter of described nose of punch of piece consistent.This drift is owing to having adopted bottom to strengthen structure; not only can not affect punching quality; and can fully strengthen the intensity of drift; and when punching; it is movable that the bottom of drift takes off in piece at stop plate and first, and it is movable that the end of drift takes off in piece second, because first and second takes off into piece inner punch accommodating hole, mates respectively with the external diameter of ram bottom and end; when drift punching, can play better protective effect and guide effect to drift, avoid drift generation bending or fracture.
Preferably, described drift is set in the drift accommodating hole in described stop plate, and it is consistent that the drift accommodating hole external diameter in this stop plate is greater than described ram bottom external diameter.
Preferably, between described upper bolster and upper padding plate and upper padding plate and train wheel bridge, by screw, be connected respectively.
Preferably, between described stop plate and upper de-plate, by screw, be connected.
