Accompanying drawing herein is merged in description and constitutes the part of this specification, it is shown that meet the enforcement of the application
Example, and for explaining the principle of the application together with description.
Detailed description of the invention
Below by specific embodiment and combine accompanying drawing the application is described in further detail.
As Figure 1-3, the embodiment of the present application provides the thimble 10 of a kind of casting mold, and this thimble 10 will be for processing
The workpiece completed ejects, in order to product is taken out from casting mold by operative employee.One end of thimble 10 is effect end 100, this
Effect end 100 is in the die cavity stretching into casting mold, and exhaust passage 101 is offered in the inside of thimble 10, and effect end 100 is offered
Steam vent 102, steam vent 102 is connected with exhaust passage 101, and steam vent 102 is for being connected with die cavity, steam vent 102
Be dimensioned to hinder raw material leak in exhaust passage 101.
The shapes and sizes of exhaust passage 101, the shapes and sizes of steam vent 102 can set flexibly according to practical situation
Put, such as: exhaust passage 101 is only opened in the position at effect end 100 place, and its shape can be irregularly shaped；Aerofluxus
Hole 102 can use circular port, and its size is as the criterion in leaking into exhaust passage 101 with obstruction raw material.And the position of steam vent 102 is permissible
It is on the sidewall of effect end 100.
Thimble 10 provided herein offers steam vent 102 on its effect end 100 so that the air in die cavity is permissible
Enter exhaust passage 101 by this steam vent 102, discharged by this exhaust passage 101 further.Owing to thimble 10 is casting moulds
The structure that tool generally all can be arranged, therefore compared to needing additionally to arrange the scheme of mold insert, this casting mold can save manufacture
Mold insert and the cost of installation mold insert so that the cost of this casting mold is relatively low.
Above-mentioned exhaust passage 101 the most through can function end 100 relative end to thimble 10, i.e. row
Gas passage 101 extends to the other end of thimble 10 from one end of thimble 10.This kind of structure can expand the sky of exhaust passage 101
Between, and then promote exhaust passage 101 and accommodate the ability of air, strengthen exhaust effect with this.Certainly, in such cases, air enters
After entering in this exhaust passage 101, can be always positioned in exhaust passage 101.But, along with casting mold fabrication cycles not
Disconnected increase, will gather substantial amounts of air in exhaust passage 101, and at this moment be accomplished by arranging the air in exhaust passage 101 further
Go out, specifically can perforate on thimble 10, this hole can connect with the space beyond casting mold, with reach discharge gas mesh
's.
When the volume of exhaust passage 101 is relatively big, and when needing perforate with further aerofluxus, this can be used for further
The hole of aerofluxus is opened on thimble 10 and functions end 100 relative one end.It is used for bearing top lift yet with this end, if row
The through so far position of gas passage 101, then the structural strength of this end will decline, and be unfavorable for reliably transmitting top lift.
To this end, pore 103 can be set out on the sidewall of thimble 10, this venthole 103 is connected with exhaust passage 101, venthole 103
It is connected for the space outerpace with casting mold.It is to say, the air entered in exhaust passage 101 will be from venthole 103
Discharging, owing to this venthole 103 is positioned on the sidewall of thimble 10, this sidewall bears the position of active force away from thimble 10, then
Reach object defined above.
The above-mentioned venthole 103 position on thimble 10 can optimize as follows: on the axis direction of thimble 10, goes out
Pore 103 is positioned at the medium position of thimble 10.This prioritization scheme can ensure that thimble 10 is in the position of relatively close die cavity
Putting, thus discharged by the air in die cavity more quickly, this venthole 103 is not easy to be cast other structures envelope of mould simultaneously
Stifled, and then ensure exhaust effect.
When on the sidewall that steam vent 102 is opened in effect end 100, owing to this sidewall needs and centre hole (this centre hole
It is generally disposed on die) coordinate, therefore by causing the air in die cavity to be not easily accessed in steam vent 102, even cannot enter
Enter in steam vent 102.In order to solve this problem, steam vent 102 can be opened on the end face of effect end 100, this end face edge
The direction the axis being perpendicular to push rod 10 extends.Owing to the end face of effect end 100 is nearest from die cavity, and it is not easy to be tied by other
Structure stops, therefore the exhaust effect of this kind of structure is the most preferable.
Further, steam vent 102 can be set at least two, each steam vent 102 interval is arranged.Along with steam vent
The quantity of 102 is continuously increased, and exhaust effect promotes therewith.Further, each steam vent 102 can be along the radial direction cloth of thimble 10
Putting, this radial direction is the direction of the axis being perpendicular to thimble 10.This arrangement is so that each steam vent 102 compares regularly
It is distributed on the end face of effect end 100, to improve stability during aerofluxus.Certainly, in order to strengthen this effect, each aerofluxus can be made
Hole 102 is along the radially uniform layout of thimble 10.
In a kind of embodiment, above-mentioned steam vent 102 can use V-shape hole, and the width of this V-shape hole could be arranged to 0.015mm.
The circulation area of this kind of steam vent 102 is bigger, is then easy to aerofluxus.For making the circulation area of steam vent 102 maximize, in effect
In the extended surface of the end face of end 100, one end of steam vent 102 extends to the side edge of end face, the other end of steam vent 102
Extend to the opposite side edge of end face.This structure makes the development length of steam vent 102 increased, and improves steam vent with this
The circulation area of 102.
The embodiment of the present application also provides for a kind of casting mold, and this casting mold comprises described by any of the above-described technical scheme
Thimble.
The foregoing is only the preferred embodiment of the application, be not limited to the application, for the skill of this area
For art personnel, the application can have various modifications and variations.All within spirit herein and principle, that is made any repaiies
Change, equivalent, improvement etc., within should be included in the protection domain of the application.
