Abstract
The utility model discloses a kind of edge-cutting and hole-punching molds with de- flash structure, and including cavity plate and punch-pin, the punch-pin is fixed on upper mold seat, and the punch-pin lower end is equipped with eccentric groove.Using the mould structure of the utility model, overlap turns round at eccentric groove into groove, overlap can be made to be rapidly separated with punch-pin, simple in structure, time saving and energy saving.
Description
Technical field
The utility model is related to edge-cutting and hole-punching mold, more particularly to a kind of trimming and piercing die with de- flash structure
Tool.
Background technology
Mold is that blank is made to become the instrument for having given shape and the product of size under external force, is widely used in punching
The compression moulding of the products such as sanction, die forging, cold-heading, extruding, metallic sintered products compacting, compression casting and engineering plastics, rubber, ceramics
Or in the forming of injection.Composite die is the punching that can complete multiple working procedure simultaneously under the one stroke of forcing press
Mould.Edge-cutting and hole-punching compound die is exactly a kind of common composite die, and trimming, punching can be completed under the one stroke of forcing press
Two procedures.However often occur overlap in use and be stuck in the situation for being not easy to deviate from mold, especially in processing
It is time-consuming, it is necessary to which worker strikes the lower overlap without deviating from using hand hammer after this thing happens when base-material is ductility high metal
Arduously, production efficiency is seriously affected.
Utility model content
The purpose of this utility model is to provide a kind of edge-cutting and hole-punching mold with de- flash structure, above-mentioned existing to solve
Technology there are the problem of, overlap can be made to be rapidly separated with punch-pin, it is time saving and energy saving.
To achieve the above object, the utility model provides following scheme：
The utility model provides a kind of edge-cutting and hole-punching mold with de- flash structure, described convex including cavity plate and punch-pin
Mould is fixed on upper mold seat, and the punch-pin lower end is equipped with eccentric groove.
Preferably, the eccentric groove is arc.
Preferably, the opening size of the eccentric groove is more than 40mm.
Preferably, the length of the eccentric groove is greater than or equal to the half of the punch-pin perimeter.
Preferably, the eccentric circular diameter of the eccentric groove slot bottom is identical with the convex mould diameter.
Preferably, the eccentricity of the off-centre operation of the eccentric groove slot bottom and the punch-pin is 10mm-40mm.
The utility model achieves following advantageous effects compared with the prior art：
The edge-cutting and hole-punching mold with de- flash structure provided by the utility model, in use, overlap is in bias
Groove shifts, and eccentric groove can be such that overlap is turned round along eccentric groove, so that overlap departs from punch-pin, it is simple in structure,
Design is reasonable, time saving and energy saving, improves production efficiency.
Description of the drawings
It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Needed in attached drawing be briefly described, it should be apparent that, the accompanying drawings in the following description is only the utility model
Some embodiments, for those of ordinary skill in the art, without having to pay creative labor, can also basis
These attached drawings obtain other attached drawings.
Fig. 1 is existing trimming punch structure diagram；
Fig. 2 is the edge-cutting and hole-punching mold schematic diagram that the utility model has de- flash structure；
Fig. 3 is that the edge-cutting and hole-punching mold that the utility model has de- flash structure takes off overlap schematic diagram.
In figure：1- upper mold seats, 2- punch-pin, 3- eccentric grooves.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
The purpose of this utility model is to provide a kind of edge-cutting and hole-punching mold with de- flash structure, to solve the prior art
There are the problem of.
To enable the above-mentioned purpose of the utility model, feature and advantage more obvious understandable, below in conjunction with the accompanying drawings and have
Body embodiment is described in further detail the utility model.
The utility model provides a kind of edge-cutting and hole-punching mold with de- flash structure, including cavity plate and punch-pin, such as Fig. 2 institutes
Show, punch-pin 2 is fixed on upper mold seat 1, and 2 lower end of punch-pin is equipped with eccentric groove 3, and eccentric groove 3 is arc, and arcuate structure can be to prevent
Only overlap hangs over situation about can not come off on groove, and eccentric groove slot bottom a points are straight between b points away from the bottom of other end punch-pin 2
Linear distance is less than the diameter of punch-pin 2, ensures that overlap can come off in the position for not setting groove from punch-pin 2,3 slot bottom of eccentric groove
Eccentric circular diameter it is identical with the diameter of punch-pin 2, eccentricity AB is 30mm, and the opening size of eccentric groove 3 is 40mm.
Punch-pin 2, which squeezes overlap when moving downward, in order to prevent makes overlap gross distortion, so as to cause situation about can not come off,
In the utility model when punch-pin 2 moves downwardly to extreme lower position, the remaining overlap of workpiece trimming is placed exactly in eccentric groove 3
Opening.
The too small situation for causing overlap that can not come off of the length of eccentric groove 3 in order to prevent, edge on the utility model punch-pin 2
The length for the eccentric groove 3 that circumferencial direction opens up is greater than or equal to the half of 2 perimeter of punch-pin.
The edge-cutting and hole-punching mold with de- flash structure provided by the utility model, during concrete application, upper mold seat 1
Punch-pin 2 is driven to move downward carry out trimming operation, with moving down for punch-pin 2, when eccentric groove 3 reaches the position of overlap, is flown
Side can shift at eccentric groove, and eccentric groove makes overlap be turned round along eccentric groove, then when punch-pin 2 rises, overlap
It can depart under the effect of gravity from punch-pin, it is time saving and energy saving, significantly improve production efficiency.
It should be noted that the eccentric groove 3 of the utility model can also use other shapes, such as trapezoidal, V-arrangement, appoint
The groove lower end of what shape is optimal for smooth curved surface or inclined-plane, is conducive to the fast-falling of overlap；3 slot bottom of eccentric groove it is inclined
The diameter of circle diameter and punch-pin 2 can not also be same.
The utility model applies specific case and the principle and embodiment of the utility model is set forth, more than it is real
The explanation for applying example is only intended to help the method and its core concept for understanding the utility model；Meanwhile for the general of this field
Technical staff, according to the thought of the utility model, in specific embodiments and applications there will be changes.To sum up,
This specification content should not be construed as the limitation to the utility model.
