State that one end connection of backplate；Weighty slider, the axial direction along the slide bar are slippingly set on the slide bar；Stretchable bullet
Property mechanism, one end are connect with the backplate, and the other end is connect with the weighty slider.
As a kind of specific embodiment, the stretchable elastic mechanism is tension spring.
As a kind of specific embodiment, the stretchable elastic mechanism is bowstring mechanism.
As a kind of specific embodiment, the weighty slider is in the cylindrical shape convenient for human hand grip.
Further, the outer wall of the weighty slider is provided with the annular anti-slip tank along its circumferentially extending.
As a kind of specific embodiment, the inner wall of the weighty slider offers the bar-shaped trough radially extended；
Multiple balls are disposed in the bar-shaped trough.
As a kind of specific embodiment, the weighty slider is connected with impact-resistant rubber close to that one end of the backplate
Pad.
As a kind of specific embodiment, the T-slot for the tail end for accommodating mandril is offered on the connector.
The beneficial technique effect that the utility model has compared with the prior art is：
It is using the connector that the tail end of mandril is affixed, handle described in one hand grip of operator, described in another hand grip
Weighty slider stretches the stretchable elastic mechanism to a degree of by pulling the weighty slider to be slid on the slide bar
The hand for holding the weighty slider is then unclamped in deformation, stops applying external force to the weighty slider, the weighty slider is drawn described
It stretches and hits the backplate, and then the inertia force of the provision for disengagement of the die casting mandril under the elastic restoring force effect of elastic mechanism
The action for extract mandril, the operation of dismounting mandril can be completed by suitably operating for several times.The die casting mandril
The action that mandril is extracted in provision for disengagement is precisely efficient, and single homework personnel can operate well, very convenient.

Specific implementation mode
In order to better understand and implement, according to the present invention will be described in detail below with reference to the accompanying drawings.
Embodiment 1
Referring to Fig. 1, a kind of provision for disengagement of die casting mandril comprising have：Backplate 2；Handle 1, with backplate 2
One end connects；Slide bar 3 is connect with the other end of backplate 2；The connector of tail end 710 for affixed mandril 7, with slide bar 3
Separate backplate 2 that one end connection；Weighty slider 4, the axial direction along slide bar 3 are slippingly set on slide bar 3；Tension spring 5,
One end is connect with backplate 2, and the other end is connect with weighty slider 4.
The tail end 710 of mandril 7 forms T-shaped with the main body bar part of mandril 7, and therefore, connector 6 offers T in outer wall
The tail end 710 of mandril 7 is caught in T-slot 610 movement of i.e. lockable mandril 7 in the radial direction thereof by the cylindrical shape of shape slot 610.
Using the die casting mandril provision for disengagement when, one hand grip handle 1 of operator, another hand grip weighty slider 4.
Weighty slider 4 is held for the ease of operator, weighty slider 4 is designed so as to the cylindrical shape of human hand grip, certainly, according to practical need
It wants, the true form of weighty slider 4 is also designed to oval or spherical, this is that those skilled in the art can be according to this implementation
What the expressed objective of example can conclude that.Operator need to only pull weighty slider 4 so that weighty slider 4 slides simultaneously on slide bar 3
Tension spring 5 is stretched simultaneously to deformation appropriate, then unclamps the hand of grip weighty slider 4, elastic restoring force of the weighty slider 4 in tension spring 5
Backplate 2 is hit under effect, and then the inertia force of the provision for disengagement of the die casting mandril drives mandril 7 to do pull action.By
The stretching tension spring 5 of appropriate number and dynamics, you can realize the extraction of mandril 7.The entire process for extracting mandril 7 only needs single homework
Personnel can be operated, and efficiently and accurately.
In order to ensure when holding weighty slider 4 and stretching tension spring 5 operator to the grip rate of tension of weighty slider 4, weighty slider 4
The a plurality of annular anti-slip tank 410 along its circumferentially extending setting is offered on outer wall.Annular shield slot 410 can significantly increase work
Stiction between the palm of the hand and the outer wall of weighty slider 4 of industry person is conducive to grip.
Wherein, the inner wall of weighty slider 4 offers the bar-shaped trough 420 radially extended, is disposed in bar-shaped trough 420
Multiple balls 421.Such design is so that weighty slider 4 on slide bar 3 when sliding, and the frictional force between weighty slider 4 and slide bar 3 is significantly
Reduce, and guidance quality of the weighty slider 4 on slide bar 3 is more preferable.
The preferred metal material of material of weighty slider 4, metal material density is big, its quality bigger of same volume, thus has
The inertia of bigger is conducive to the extraction of mandril 7.
Weighty slider 4 hit backplate 2 when will produce certain noise, it is therefore preferred that weighty slider 4 close to backplate 2 that
End is connected with impact-resistant rubber pad 430.Certainly, further, the impact-resistant rubber material of hard can also be used in backplate 2, into one
Step reduces weighty slider 4 and hits noise caused by backplate 2.
Embodiment 2
Referring to Fig. 4, the present embodiment and the primary structure of embodiment 1 are not much different, main difference is that the present embodiment
In, the elastic force that weighty slider 4 hits backplate 2 is provided by bowstring mechanism 8.Bowstring mechanism 8 is formed by bending 820 chords 810.Bow 820 is solid
It is scheduled on slide bar 3,810 one end of string and the end of bow 820 are affixed, and the other end and weighty slider 4 are affixed.In use, by connector 6 with
After the tail end 710 of mandril 7 connects, prudent sliding block 4 is held, pulls string 810, then loose one's grip, rebound of the weighty slider 4 in bow 820
It quickly moves and beats to backplate 2 towards backplate 2 under force effect, and then the inertia of the provision for disengagement because of the die casting mandril,
The provision for disengagement of the die casting mandril drives mandril 7 to do pull action.
The utility model is not limited to the above embodiment, if the various changes or deformation to the utility model do not take off
Spirit and scope from the utility model, if these changes and deformation belong to the claims and equivalents of the utility model
Within the scope of, then the utility model is also intended to comprising these changes and deformation.
