Abstract

The invention relates to the technical field of dies, and discloses an ejection mechanism for an inner-outer-circle stamping die. The ejection mechanism comprises an upper die, the upper die comprises an upper die plate connected with a center-hole male die through an upper padding plate, the center-hole male die is sleeved with an outer circle female die, an upper stripper plate is embedded into the gap between the center-hole male die and the outer circle female die and can move up and down along the gap, and the ejection face of the upper stripper plate is adaptive to a finished product part in shape; a plurality of through holes are formed in the positions, corresponding to the upper stripper plate, of the upper die plate and the upper padding plate, and a stopping device for limiting downward movement of the upper stripper plate is arranged on the upper die. The upper stripper plate is arranged between the center-hole male die and the outer circle female die, and the ejection face of the upper stripper plate is adaptive to the finished product part in shape so that the ejection mechanism can eject the finished product part out integrally, and even if the finished product part is embedded into the female die too tightly, the finished product part will not be deformed; the ejection mechanism has the advantages that the structure is simple, ejection is convenient to carry out, and the part will not be deformed.

Description

A kind of ejecting mechanism of inside and outside circle diel
Technical field
The present invention relates to technical field of mold, more particularly, particularly a kind of ejecting mechanism of inside and outside circle diel.
Background technology
Inside and outside circle diel of the prior art has upper die and lower die, in the time using mould, patrix is fixed on the upper connecting base of stamping machine, and counterdie is fixed on lower connecting base, after part punching completes, finished product is generally all embedded in die die cavity, after need to using ejecting mechanism pushing-off product, could from mould, take out, the ejecting mechanism of general mould is all that knock-pin directly ejects, if finished product is embedded in tension in die, knock-pin can be by the distortion of finished product top, and the finished product of taking-up is also by displacement waste material.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, ejecting mechanism that finished product after ejecting conveniently, ejecting does not have the dangerous inside and outside circle diel of distortion.
In order to achieve the above object, the technical solution used in the present invention is as follows:
A kind of ejecting mechanism of inside and outside circle diel, comprise patrix, described patrix comprises a cope match-plate pattern, described cope match-plate pattern is connected with a mesopore punch by a upper padding plate, described mesopore punch is also arranged with an outer cupping tool outward, in space between described mesopore punch and outer cupping tool, be embedded with a loading and unloading material plate, described loading and unloading material plate can move up and down along described space, and the face that ejects of described loading and unloading material plate and the shape of fabricated part adapt, described cope match-plate pattern, on described upper padding plate and with described loading and unloading material Board position opposite position, be provided with multiple through holes, on described patrix, be also provided with the stop device that a spacing described loading and unloading material plate moves down.
Preferably, described stop device comprises that being arranged at one on described loading and unloading material plate outer wall encloses the first projection, also comprises the second projection being arranged on described outer cupping tool inwall, and described the second projection is arranged at the below of described the first projection.
Preferably, described mesopore punch middle part is also provided with a connecting hole.
Preferably, described through hole quantity is 6, uniform along described cope match-plate pattern axis.
Compared with prior art, the invention has the advantages that: by loading and unloading material plate being set between cupping tool and mesopore punch outside, and the face that ejects of loading and unloading material plate and the shape of fabricated part adapt, ejecting mechanism can eject fabricated part entirety, fabricated part can local pressure, can not cause fabricated part distortion even if fabricated part embeds tension in die yet, have advantages of simple in structure, eject conveniently, part can not be out of shape.
Brief description of the drawings
Below in conjunction with drawings and Examples, invention is described further.
Fig. 1 is the structural representation of the ejecting mechanism of inside and outside circle diel of the present invention.
Description of reference numerals: 1, cope match-plate pattern, 2, upper padding plate, 3, mesopore punch, 4, outer cupping tool, 5, space, 6, loading and unloading material plate, 7, through hole, 31, connecting hole, 41, the second projection, 61, eject face, 62, the first projection.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be described in further detail.
Consult shown in Fig. 1, provided by the invention 1, a kind of ejecting mechanism of inside and outside circle diel, comprise patrix, patrix comprises a cope match-plate pattern 1, cope match-plate pattern 1 is connected with a mesopore punch 3 by a upper padding plate 2, the outer outer cupping tool 4 that is also arranged with of mesopore punch 3, in space 5 between mesopore punch 3 and outer cupping tool 4, be embedded with a loading and unloading material plate 6, loading and unloading material plate 6 can move up and down along space 5, and the face that ejects 61 of loading and unloading material plate 6 adapts with the shape of fabricated part, cope match-plate pattern 1, on upper padding plate 2 and with loading and unloading material plate 6 position opposite positions, be provided with multiple through holes 7, on patrix, be also provided with the stop device that a spacing loading and unloading material plate 6 moves down.By loading and unloading material plate 6 being set between cupping tool 4 and mesopore punch 3 outside, and the face that ejects 61 of loading and unloading material plate 6 adapts with the shape of fabricated part, ejecting mechanism can eject fabricated part entirety, fabricated part can local pressure, can not cause fabricated part distortion even if fabricated part embeds tension in die yet, have advantages of simple in structure, eject conveniently, part can not be out of shape
In the present embodiment, stop device comprises that being arranged at one on loading and unloading material plate 6 outer walls encloses the first projection 62, also comprises that the second projection 41, the second projections 41 that are arranged on outer cupping tool 4 inwalls are arranged at the below of the first projection 62.The second projection 41 can prevent loading and unloading material plate 6 landing from space 5, plays the effect of Descending fibers.This first projection 62 and the second projection 41 also can be arranged on the contact-making surface between loading and unloading material plate 6 and mesopore punch 7, also do not affect enforcement of the present invention.
Preferably, mesopore punch 3 middle parts are also provided with a connecting hole 31.This connecting hole 31 is for holding connecting bolt, this connecting bolt is connected with the screwed hole on upper padding plate 2 through connecting hole 31, and upper padding plate 2 is connected with mesopore punch 3, and another convenient can being used as is breathed freely, while preventing mesopore punch 3 die mould, between bottom surface and blank, assemble gas.Also save mold materials.Through hole 7 quantity are 6, uniform along cope match-plate pattern 1 axis.Knock-pin on stamping machine can be connected with loading and unloading material plate 6 by through hole 7, drives 6 rise and fall of loading and unloading material plate by knock-pin, thereby drives this ejecting mechanism pushing-off product part.
Although described by reference to the accompanying drawings working of an invention mode; but the patent owner can make various distortion or amendment within the scope of the appended claims; as long as be no more than the described protection domain of claim of the present invention, all should be within protection scope of the present invention.
