Abstract
The utility model discloses a reverse buckle ejection mechanism of a die, which includes a left forming sheet and a right forming sheet, wherein the left forming sheet and the right forming sheet are matched; the left forming sheet and the right forming sheet are both mounted in a channel of a lower template; the front part of the channel is designed into a V-shaped chute; the tail ends of the left forming sheet and the right forming sheet are matched with an elastic resetting mechanism fixed on the lower template; and the elastic resetting mechanism includes a spring and a guide post. The reverse buckle ejection mechanism of the die is simple in structure, reasonable in design, easy to maintain and use, and is suitable for processing and ejecting a reverse buckle of a small product.
Description
Technical field
The utility model relates to a kind of mould structure, specifically a kind of back-off ejecting mechanism of mould.
Background technology
In the prior art, when plastic product will have been made back-off, adopt following method to solve usually: one, to do the undercut structure of loosing core at the back-off place; Two, use secondary ejecting mechanism that the back-off place is carried out forced stripper mechanism.
When the buckle shape hour, because the mould design is restricted, just can't use above-mentioned first method to realize, and the use second method will make the more complicated and great cost that increased of mould structure, die life is low, the mould development cost is too high.
The utility model content
The purpose of this utility model is to overcome traditional moulds back-off ejecting mechanism and is applied in existing deficiency on the small size back-off product, and a kind of mould back-off ejecting mechanism is provided.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of back-off ejecting mechanism of mould, include left matrix band, right matrix band, and it is characterized in that:
Described left matrix band cooperates with right matrix band;
Described left matrix band, right matrix band are installed in the conduit of lower bolster;
The be in the shape of the letter V skewed slot design of the front portion of described conduit;
The flexible restoring organ that the tail end and of described left matrix band, right matrix band is fixed on lower bolster matches;
Described flexible restoring organ includes spring and guide pillar;
The bottom of described left matrix band, right matrix band all is shaft-like, and the middle part all is thin rod shape, and forming blocks has all been designed on top;
The middle part diameter of described left matrix band, right matrix band is less than the diameter of top and bottom;
Forming blocks on the described left matrix band is adjacent to forming blocks on the right matrix band and cooperates the cavity that forms a shaped article back-off.
Operation principle of the present utility model is, after the product that has a back-off machines, in producing the process that Lu ejects, back-off drives left matrix band, right matrix band rises, portion in left and right matrix band is thin rod shape, and the certain elastic deformation ability is specifically arranged, in the process that left and right matrix band rises, under the cooperation of V font skewed slot, the forming blocks of left and right matrix band is separated, and back-off is deviate from, after deviating from, left and right matrix band resets under the drive of flexible restoring organ.
Of the present utility model simple in structure, reasonable in design, be easy to safeguard and use, be applicable to the small size product back-off processing and eject.

The specific embodiment
To understanding of the present utility model, existing 1,2 pair of the utility model is by reference to the accompanying drawings made further instruction for convenient.
Embodiment:
A kind of back-off ejecting mechanism of mould includes left matrix band 4, right matrix band 5, it is characterized in that: described left matrix band 4 cooperates with right matrix band 5; Described left matrix band 4, right matrix band 5 are installed in the conduit 3 of lower bolster 1; The be in the shape of the letter V skewed slot design of the front portion of described conduit 3; The flexible restoring organ 6 that the tail end and of described left matrix band 4, right matrix band 5 is fixed on lower bolster 1 matches; Described flexible restoring organ 6 includes spring and guide pillar; The bottom of described left matrix band 4, right matrix band 5 all is shaft-like, and the middle part all is thin rod shape, and forming blocks has all been designed on top; The middle part diameter of described left matrix band 4, right matrix band 5 is less than the diameter of top and bottom; Forming blocks on the described left matrix band 4 is adjacent to forming blocks on the right matrix band 5 and cooperates the cavity that forms shaped article 2 back-offs.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified to the equivalent embodiment of equivalent variations, but all technical solutions of the utility model contents that do not break away from,, all still belong in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does according to technical spirit of the present utility model.
Claims (1)
1. the back-off ejecting mechanism of mould includes left matrix band, right matrix band, it is characterized in that: described left matrix band cooperates with right matrix band; Described left matrix band, right matrix band are installed in the conduit of lower bolster; The be in the shape of the letter V skewed slot design of the front portion of described conduit; The flexible restoring organ that the tail end and of described left matrix band, right matrix band is fixed on lower bolster matches; Described flexible restoring organ includes spring and guide pillar; The bottom of described left matrix band, right matrix band all is shaft-like, and the middle part all is thin rod shape, and forming blocks has all been designed on top; The middle part diameter of described left matrix band, right matrix band is less than the diameter of top and bottom; Forming blocks on the described left matrix band is adjacent to forming blocks on the right matrix band and cooperates the cavity that forms a shaped article back-off.
