Description
Technical field
The utility model relates to pouring molten steel technical fields, more particularly, to a kind of exhaust that solution sand core type chamber is felt suffocated
Plug.
Background technique
Heat-resisting steel product is excessively high in the medium-sized chamber air pressure of casting process, needs that type intracavity gas is discharged in time, can just make iron
Water quickly fills with type chamber, therefore needs to be exhausted using venting plug in actual production process.
Original venting plug uses enclosed construction, and structure is as depicted in figs. 1 and 2, is mounted on the sand core of molding sand, monolithic devices chamber
It is in air-tight state in casting process, is not connected with atmosphere, exhaust process can only be by the gas permeability of sand core itself come complete
At, portion gas cannot quick discharge type chamber, hinder molten iron flow speed and direction, keep cavity filling process not smooth, increase cold shut
Risk.Venting principleand additionally, due to the venting plug is to utilize 30/50 mesh precoated sand in coremaking bonding process since sand grains is straight
Diameter is big, and own gap can be generated in bonding process, using sand core since the gap of the not fine and close generation of institutional framework is exhausted；By
In the discharge characteristic, coremaking cannot be carried out by high temperature and pressure, can only be carried out by traditional manual core making, worker's amount of labour
Huge, quality cannot be guaranteed, and sand core coremaking efficiency is very low, and the buying of 30/50 precoated sand is difficult.
Utility model content
In view of this, the purpose of this utility model is in view of the deficiencies of the prior art, to provide a kind of solution sand core type chamber and suppress
The venting plug of gas, the venting plug good exhaust effect, low manufacture cost.
In order to achieve the above objectives, the utility model uses following technical scheme:
A kind of venting plug for solving sand core type chamber and feeling suffocated, the venting plug are conical hollow structure, including exhaust obturating plug, institute
It states and air exhaust rod is set on exhaust obturating plug, exhaust head is set in the air exhaust rod, and the apex angle of the exhaust obturating plug is 6 °, the exhaust
The apex angle of bar is 2 °, and the apex angle of the exhaust head is 1 °.
Further, the exhaust obturating plug, air exhaust rod and exhaust head total height are 170mm.
Further, the height of the exhaust obturating plug is 20mm, and the height of the air exhaust rod is 65mm.
Further, the exhaust obturating plug, air exhaust rod and exhaust head are an integral molding structure.
The beneficial effects of the utility model are:
1, the utility model discloses a kind of venting plug that solution sand core type chamber is felt suffocated, and improves to original venting plug,
Improved venting plug use communicating structure, using equipment coremaking, monolithic devices chamber in casting process by venting plug realize and
Atmosphere communicates, and is more advantageous to quickly flowing, fill type for molten iron.
2, the venting principleand of original venting plug is using bulky grain coarse sand in coremaking bonding process, due to sand grains diameter
Greatly, own gap can be generated in bonding process, using sand core since the gap of the not fine and close generation of institutional framework is exhausted.Due to
Discharge characteristic cannot carry out coremaking by high temperature and pressure, can only be carried out by traditional manual core making, production efficiency is low, labor
Fatigue resistance is big.And the venting principleand of improved venting plug is exhausted using communicating structure, without the concern for the cause of sand core
Close performance, even if sand core compactness is very strong, does not influence exhaust effect still by equipment coremaking.Therefore life can be greatly improved
Efficiency is produced, labor intensity of workers is mitigated, reduces production cost.

In figure: 1- is vented obturating plug, 2- air exhaust rod, 3- exhaust head.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
Embodiment 1
As depicted in figs. 1 and 2, the venting plug before transformation is enclosed construction, is mounted on sand core, is highly with width
36mm is exhausted by 30/50 mesh overlay film sand permeability, and venting quality is poor, and in view of needing the bonding using precoated sand
Gap is exhausted, and needs to carry out manual core making, difficulty is big, at high cost.
The utility model discloses a kind of venting plug that solution sand core type chamber is felt suffocated, and improves, changes to original venting plug
Structure after is as shown in Figure 3 and Figure 4, and venting plug is conical hollow structure, including exhaust obturating plug 1, the lower end peace of exhaust obturating plug 1
On sand core, wherein air exhaust rod 2 is arranged on exhaust obturating plug 1, exhaust head 3 is set in air exhaust rod 2, is vented obturating plug 1, air exhaust rod 2
It is an integral molding structure with exhaust head 3, the apex angle α for further limiting exhaust obturating plug 1 is 6 °, is arranged to pyramidal structure, facilitates peace
Dress；The apex angle ss of air exhaust rod 2 is 2 °, and the apex angle γ of exhaust head 3 is 1 °, and the venting plug contour structures are longer, and design is in an inverted cone,
Be conducive to gas to be quickly discharged from type chamber, it being capable of rapid shaping when making venting plug.
Venting plug total height is 170mm in the utility model, and the height of exhaust obturating plug 1 is 20mm, and the height of air exhaust rod 2 is
65mm, the outer diameter of air exhaust rod 2 are greater than the outer diameter of exhaust obturating plug 1 and exhaust head 3, facilitate pick-and-place and installation the utility model.
Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, this field
Other modifications or equivalent replacement that those of ordinary skill makes the technical solution of the utility model, it is practical without departing from this
The spirit and scope of new technique scheme should all cover in the scope of the claims of the utility model.
