Abstract
This utility model relates to a kind of core with exhaust apparatus, and including core body, arbor and air bag, described core body inner hollow is provided with arbor；A nylon tube it is provided with outside described arbor；Asbestos cord uniformly it is enclosed with outside described nylon tube.Gas and steam that core can be produced by this utility model are discharged, it is ensured that the core of the band exhaust structure of casting quality.
Description
Technical field:
This utility model relates to a kind of core with exhaust apparatus, belongs to hot investment casting field.
Background technology:
Core is for manufacturing the material of core in Foundry Production, and typically by casting model powder, molding sand glues
The knot Modeling Material such as agent and additional thing mixes according to a certain percentage.During cast,
Binding agent and the Organic substance of core weight can burn releasing gas, and the residual water branch in core
By thermal evaporation, if these gases are not excluded for, then foundry goods can be caused to produce gas.
Utility model content:
This utility model provides a kind of gas that can be produced by core and steam to discharge, it is ensured that
The core of the band exhaust structure of casting quality.
In order to solve the problem existing for background technology, this utility model is to use techniques below side
Case:
A kind of core with exhaust apparatus, including core body, arbor and air bag, in described core body
Portion's hollow is provided with arbor；A nylon tube it is provided with outside described arbor；Outside described nylon tube uniformly
It is enclosed with asbestos cord.
Further, described nylon tube inner hollow, inwall is evenly distributed with steam vent.
Further, described steam vent pitch-row 50mm, hole to core surface distance 10-15mm,
Aperture 3-5mm.
Further, described air bag connects with core body one end.
Further, described nylon tube caliber is more than arbor diameter.
Further, described air bag can be dismantled after cast terminates.
Before pouring into a mould, the air bag of core body one end is compressed, in casting process, air bag by
Cumulative greatly, by the gas in core body via outside arbor surround nylon tube on steam vent, pass through
Asbestos cord layer sucks inside air bag.Air bag can be pulled down after terminating by cast, just completes exhaust process.
Gas and steam that core can be produced by this utility model are discharged, it is ensured that casting quality
The core of band exhaust structure.
This utility model has the beneficial effect that simple in construction, good exhaust effect.
Accompanying drawing illustrates:
Fig. 1 is this utility model overall structure schematic diagram；
Labelling in accompanying drawing: 1, asbestos cord；2, arbor；3, nylon tube；4, core body；5、
Air bag.
Fig. 2 is this practical nylon pipe schematic diagram；
Labelling in accompanying drawing: 3, nylon tube；6, steam vent.
Detailed description of the invention:
This utility model this utility model provides a kind of gas that can be produced by core and water to steam
Gas is discharged, it is ensured that the core of the band exhaust structure of casting quality.
In order to solve the problem existing for background technology, this utility model is to use techniques below side
Case:
A kind of core with exhaust apparatus, including core body, arbor and air bag, in described core body
Portion's hollow is provided with arbor；A nylon tube it is provided with outside described arbor；Outside described nylon tube uniformly
It is enclosed with asbestos cord.
As a kind of preferred embodiment of the present utility model, described nylon tube inner hollow, inwall
It is evenly distributed with steam vent.
As a kind of preferred embodiment of the present utility model, described steam vent pitch-row 50mm, hole
To core surface distance 10-15mm, aperture 3-5mm.
As a kind of preferred embodiment of the present utility model, described air bag connects with core body one end.
As a kind of preferred embodiment of the present utility model, described nylon tube caliber is straight more than arbor
Footpath.
As a kind of preferred embodiment of the present utility model, described air bag can be after cast terminates
Dismounting.
Before pouring into a mould, the air bag of core body one end is compressed, in casting process, air bag by
Cumulative greatly, by the gas in core body via outside arbor surround nylon tube on steam vent, pass through
Asbestos cord layer sucks inside air bag.Air bag can be pulled down after terminating by cast, just completes exhaust process.
