Exhibition, mold manufacturing is higher and higher with assembly precision, and people increasingly pursue high quality, close to perfect mould.For on mould
Any one details all constantly improving, the pin that high frequency uses forces people to find safer, simple, reliable side
Formula dismounts.
During mold attaching/detaching, the common device for pulling out pin of people is completed by the momentum of moment, this is right
The damage of pin is very big, and dangerous factor, and extremely expends energy.
The content of the invention
The object of the present invention is to provide a kind of pin removal device, removes effortlessly, and can effectively reduce to pin
Damage.
To achieve the above object, the technical solution adopted in the present invention is：Bar, connecting rod and company are struck including base, bias
Fitting, the head that bias strikes bar are cam, and the cam is arranged on base, and bias strikes bar and the angled setting of base, connecting rod
Through the cam, connector is stretched out from connecting rod radially across and from the bottom of base, in use, connector with it is to be removed
Pin connection, bias is struck bar and is rotated by rotation axis of connecting rod, described when the eccentric angle struck between bar and base is gradually reduced
The distance of point to the central axis of connecting rod on the surface of cam with base contacts gradually increases.
Preferably, the base is equipped with limiting slot, and the end of the cam is placed in limiting slot.
Preferably, the base is equipped with height of multiple regulating parts to adjustment base.
Preferably, the regulating part is adjusting screw, is equipped with diverse location on base and matches somebody with somebody with the adjusting screw
The screw hole of conjunction, adjusting screw are arranged in screw hole.
Preferably, the end of the connecting rod is equipped with the fixed pin for preventing from deviating from from cam.
Preferably, the quantity of the connector is at least one, when the quantity of connector is multiple, different connectors
Specification is different.
Preferably, the connector is attachment screw, and the attachment screw is connected with pin to be removed during use.
Preferably, the bias strikes that bar is Y-shaped, and connecting rod strikes the jag position of bar through Y-shaped bias.
After adopting the above technical scheme, the present invention has the positive effect that：
(1) pin removal device of the invention, the cam structure on bar is struck using bias and drives attachment screw on base
Movement, by the connection of attachment screw and pin, smoothly takes out the pin being fixed in pin fixed plate or other structures.It is above-mentioned
The dismantlement work of pin is completed by way of gradually increasing load, protects the screw thread on pin and pin well,
Damage to pin is preferably minimized；
(2) because the quantity of attachment screw can be multiple and different specifications, the pin to different sizes can be completed
Being dismantled for task, device are adaptable；
(3) height of base can be adjusted by regulating part, and regulating part can be arranged on base at diverse location, from
And adapt to various sizes of working face requirement.

Embodiment
The present invention is described in further detail with reference to the accompanying drawings and detailed description.
In the present invention, unless otherwise clearly defined and limited, term " installation ", " connected ", " connection ", " fixation " etc.
Term should broadly understood, for example, it may be fixedly connected or be detachably connected, or integrally；Can be that machinery connects
Connect or be electrically connected；It can be directly connected, can also be indirectly connected by intermediary, can be in two elements
The connection in portion or the interaction relationship of two elements.For the ordinary skill in the art, can be according to specific feelings
Condition understands the concrete meaning of above-mentioned term in the present invention.
As shown in Figs. 1-3, bar 2, connecting rod 3, connector are struck for the pin removal device of the present invention, including base 1, bias
4th, regulating part 6, screw hole 7 and fixed pin 8.The head that bias strikes bar 2 is cam, and the cam is arranged on base 1, and bias strikes bar
2 are equipped with limiting slot 5 with 1 angled setting of base, base 1, and the end of the cam is placed in limiting slot 5, and limiting slot 5 is
Bias strikes bar 2 and provides guiding, it is moved in specified directions, and is unlikely to double swerve.
Bias strikes that bar 2 is Y-shaped, and connecting rod 3 strikes the jag position of bar 2 through Y-shaped bias, and the end of connecting rod 3 is set
There is fixed pin 8, fixed pin 8 can prevent connecting rod 3 from striking to deviate from bar 2 from bias.Bias strikes bar 2 can be with connecting rod 3 for rotation
Shaft rotates, and when the angle that bias is struck between bar 2 and base 1 is gradually reduced, the point contacted on the surface of the cam with base 1 arrives
The distance of the central axis of connecting rod 3 gradually increases, and so can progressively lift pin.
Connector 4 is stretched out from connecting rod 3 radially across and from the bottom of base 1, is had on base 1 and is easy to connector 4
The bar hole passed through, in use, connector 4 is connected with pin to be removed.In the present embodiment, connector 4 can be connection
Screw, attachment screw is connected with pin to be removed during use.The quantity of attachment screw can be one, or it is multiple,
When quantity is multiple, the size and specification of different attachment screws are different, by setting the attachment screw of different size, Ke Yishi
Dismountings of the Ying Yu to different pins uses.
Base 1 is equipped with multiple regulating parts 6, and regulating part 6 can be with the height of adjustment base 1.Regulating part 6 can adjust spiral shell
Follow closely, there is screw hole 7 on base 1, adjusting screw is bolted in screw hole 7, and screw hole 7 can be arranged on base 1 different positions
Place is put, by selecting to use different screw holes 7, so as to adapt to the requirement in different work face, when work surface very little, may be selected
Operated close to the screw hole 7 of middle part, you can smoothly extract pin.Regulating part 6 can also be spirally connected with 1 bottom of base
Adjusting screw, by adjusting the adjusting screw from the size of 1 bottom prominent length of base, to adjust the height of base 1.
The pin removal device working condition of the present invention is as follows：When needing to dismantle the pin in pin fixed plate 9, the bottom of by
Seat 1 is placed in pin fixed plate 9, is adjusted regulating part 6, is made 1 force balance of base.Connector 4 is connected with pin, is then pressed
Pressure bias strikes bar 2, the eccentric bar 2 that strikes is moved towards close to the direction of base 1, eccentric at this time to strike guiding area of the bar 2 in limiting slot 5
Interior movement, device is produced to be removed along the axial power of connector 4, pin in the motion process that bias strikes 2 head cam of bar.
It will be apparent to those skilled in the art that technical solution that can be as described above and design, make other various
It is corresponding to change and deformation, and all these change and deformation should all belong to application claims protection domain it
It is interior.
