Description
Technical field
This utility model relates to a kind of demoulding equipment, particularly relates to a kind of installation pneumatic jack more firm, reliable.
Background technology
It is removed from the molds, it is generally required to product is entered for convenience of product after existing plasthetics injection mo(u)lding
Row automatic demoulding, existing product stripping mode has multiple, such as, ejected from rear mold by product by thimble
The demoulding, or by arranging pneumatic jack on mould, make pneumatic jack connect with die cavity, by injecting gases at high pressure profit
With air pressure product ejected and realize the demoulding.
For using the mode of the pneumatic jack demoulding, can effectively simplify the structure of mould, control simple and convenient, no
Easily damaging product, stripping result is good.Existing pneumatic jack generally comprises valve main body and plunger tip, by by gas
Mouth main body inserts the pore that mould is reserved, is passed through gases at high pressure when the demoulding, but, due to gas
Air pressure is the highest, lacks a kind of ruggedized construction between existing pneumatic jack and mould, and therefore, traditional pneumatic jack exists
Likely under the effect of gases at high pressure, undesirably fall off mould during the demoulding, so that the demoulding was lost efficacy, reduce reliable
Property.
Utility model content
The purpose of this utility model is that providing a kind of installs pneumatic jack more firm, reliable.
To achieve these goals, the pneumatic jack that this utility model provides includes valve main body and plunger tip, described top
Core is socketed in described valve main body slidably, so that the sealing-plug of described plunger tip front end and described valve main body
The gas outlet of front end opens or closes, and the rear end of described valve main body is provided with expansion buckle, described expansion buckle
Inwall be provided with for screw thread connect and make the screw thread of described expansion buckle outward expansion.
Compared with prior art, owing to this utility model is by arranging inflating clip in the rear end of described valve main body
Button, and in expansion buckle, it is provided with screw thread, therefore, when pneumatic jack is fixed in mould, by a spiral shell
After nail is threadedly connected to expansion buckle, described expansion buckle outward expansion can be made, so that described valve main body
Be fastened in firmly in mould, effectively prevent when product is in the demoulding because of be passed through the air pressure of gases at high pressure excessive and
Make whole pneumatic jack eject mould, install the most solid and reliable.
It is preferred that described expansion buckle includes at least two clamping parts, between described clamping part, there is interval trough.
Specifically, the outer ledge of described clamping part is provided with protuberance.
Described sealing-plug is made to seal described gas outlet it is preferred that be provided with between described plunger tip and described valve main body
Back-moving spring.
It is preferred that one end of the described plunger tip relative with described sealing-plug is fixed with and the central shaft of described plunger tip
Vertical pivot pin, described back-moving spring is socketed on described plunger tip and one end and supports with described valve main body, another
End is supported with described pivot pin.
It is preferred that offer the passage that some and described gas outlet connects on the sidewall of described valve main body.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model pneumatic jack.
Fig. 2 is the decomposing schematic representation of this utility model pneumatic jack.
Fig. 3 is the sectional view of this utility model pneumatic jack.
Detailed description of the invention
By describing technology contents of the present utility model, structural feature, the effect that realized in detail, below in conjunction with
Embodiment also coordinates accompanying drawing to be explained in detail.
As shown in Figure 1, Figure 2 and Figure 3, this utility model pneumatic jack 100 includes valve main body 1 and plunger tip 2,
Described plunger tip 2 is socketed in described valve main body 1 slidably, so that the sealing-plug 21 of described plunger tip 2 front end
Open or close with the gas outlet 11 of described valve main body 1 front end;Offer on the sidewall of described valve main body 1
There is the passage 12 that some and described gas outlet 11 connects.The rear end of described valve main body 1 is provided with expansion buckle
3, the inwall of described expansion buckle 3 is provided with and connects for screw thread and make described expansion buckle 3 outward expansion
Screw thread 4.Specifically, described expansion buckle 3 includes at least two clamping parts 31, has between described clamping part 31
There is interval trough 32.The outer ledge of described clamping part 31 is provided with protuberance 31a, and described expansion buckle 3 is the most swollen
Time swollen, described protuberance 31a can press in the pore of mould with mould clamping regularly.Described plunger tip 2
And it is provided with the back-moving spring 5 making described sealing-plug 21 seal described gas outlet 11 between described valve main body 1.
One end of the described plunger tip 2 relative with described sealing-plug 21 is fixed with the central axis with described plunger tip 2
Pivot pin 22, described pivot pin 22 is slidingly arranged in described interval trough 32, and described back-moving spring 5 is socketed on
Described plunger tip 2 and one end are supported with described valve main body 1, and the other end is supported with described pivot pin 22.
During use, breather line is connected to described valve main body 1, and described valve main body 1 is inserted the gas of mould
In hole, being then connected to described expansion buckle 3 by screw thread, described expansion buckle 3 outward expansion makes institute
Stating clamping part 31 to be resisted against on mould, at this moment, described pneumatic jack 100 is i.e. securable to mould, and described valve
Main body 1 connects with die cavity;Afterwards, gases at high pressure are carried by breather line and valve main body 1, and utilize
Sealing-plug 21 described in Pneumatic pushing, make described sealing-plug 21 protruding and depart from described gas outlet 11,
So that described gas outlet 11 is opened;Now, gases at high pressure can be injected into mould by described passage 12
Intracavity pushing tow product make its demoulding.After stopping supply, under the restoring force effect of described back-moving spring 5,
Described sealing-plug 21 resets and is sealed described gas outlet 11.
Compared with prior art, owing to this utility model is by arranging expansion in the rear end of described valve main body 1
Buckle 3, and in expansion buckle 3, it is provided with screw thread 4, therefore, when pneumatic jack 100 is fixed in mould,
After being connected to expansion buckle 3 by a screw thread, described expansion buckle 3 outward expansion can be made, so that
Described valve main body 1 is fastened in mould firmly, effectively prevents when product is in the demoulding because being passed through high pressure gas
The air pressure of body is excessive and makes whole pneumatic jack 100 eject mould, installs the most solid and reliable.
Above disclosed only preferred embodiments of the present utility model, can not limit this reality with this certainly
By novel interest field, the equivalent variations therefore made according to this utility model claim, still fall within
The scope that this utility model is contained.
