Beneficial effect using above-mentioned further scheme is：Die joint arrange portion gas by setting pressure sand ring to enter
In tapered rod and central discharge air needle, the gas in forming cavity is enabled to permeate discharge, but can prevent molten iron from entering again simultaneously, arranged
Gas effect is good, improves product quality.
Further, the tapered rod is up big and down small frustum cone structure, and the gradient of the tapered rod is 5 °~20 °.
Further, it is greater than the tide mould sand of 50mm in the drag box forming cavity equipped with thickness, the tide mould sand is located at casting
Between tapered rod.
Beneficial effect using above-mentioned further scheme is：Tapered rod is conducive to improve product matter using suitable gradient
Amount, avoids gradient is too small from being unfavorable for moulding and molding, also avoids gradient excessive so that gradually apart from too in tapered rod microcephaly part
Far it is unfavorable for gas infiltration discharge.
Further, the height of the tapered rod is greater than or equal to casting height, and the both ends of tapered rod exceed the two of casting
End is flushed with the both ends of casting, is conducive to the infiltration discharge of gas.
Further, peripheral exhaust needle is additionally provided at the top of the cope, the peripheral exhaust needle is disposed around the center
The surrounding of exhaust needle.

Specific embodiment
The embodiments of the present invention is illustrated by particular specific embodiment below, those skilled in the art can be by this
Content disclosed by specification understands other advantages and effect of the utility model easily.
It should be clear that the term of such as "upper", "lower", "left", "right", " centre " and " one " cited in this specification, also
Only being illustrated convenient for narration, rather than to limit the enforceable range of the utility model, relativeness is altered or modified,
Under the content of no substantial changes in technology, when being also considered as the enforceable scope of the utility model.
As shown in Figures 1 to 4, the revolving body casting mould of the utility model embodiment, including cope 1 and drag box 7,
Drag box 1 is equipped with the molding forming cavity of casting 5, and the center of forming cavity is equipped with the internal tapered rod 3 for hollow structure, cope 1
Equipped with the internal central discharge air needle 2 for hollow structure, when cope 1 and the molding of drag box 7, central discharge air needle 2 and tapered rod 3
Contraposition connection forms blast pit, and the gas in casting process is constantly penetrated into blast pit and is discharged.Cope 7
Top is additionally provided with peripheral exhaust needle 4, and peripheral exhaust needle 4 is disposed around the surrounding of central discharge air needle 2, and molten iron is injected by sprue 6
Type chamber, when peripheral exhaust needle 4 is filled by molten iron, gas can not be discharged by peripheral exhaust needle 4 again, just can only be arranged by center
2 discharge gas of air tube.The quantity of the upper conical stick of drag box 7 selects to be arranged according to demand, the quantity and tapered rod of central discharge air needle
Quantity is correspondingly arranged.
As shown in Figures 1 to 4, tapered rod 3 is up big and down small frustum cone structure, the stub end and central discharge air needle 2 of tapered rod 3
Connection, the preferred height of tapered rod 3 are greater than or equal to casting height, and both ends or and casting of the both ends of tapered rod beyond casting
Both ends flush, the both ends of tapered rod 3 as close as the both ends of casting 5 be conducive to it is multiple rows of go out gas.The gradient α of tapered rod
Be 5 °~20 °, avoid gradient is too small from causing molding and moulding difficult, also avoid the excessive small head end for causing tapered rod 3 of gradient from
Casting 5 is unfavorable for gas and penetrates into blast pit too far.It is greater than the tide mould sand 8 of 50mm in 7 forming cavity of drag box equipped with thickness,
Tide mould sand has gas permeability, gas is passed through, but molten iron can not pass through, tide mould sand 8 be located at casting 5 and tapered rod 3 it
Between, gas penetrates into blast pit from the molten iron of casting forming cavity.When tapered rod structure does big, the thickness of tide mould sand 8
Thinning, although the thinning tapered rod that is conducive to of tide mould sand is close with casting, convenient for infiltration gas, tide mould sand is excessively thin to cause moulding
It is bad, therefore tide mould sand needs to keep suitable thickness.
As shown in Figures 1 to 4, when cope 1 and drag box 7 mold, the top of the bottom of cope 1 and drag box 7 it
Between be installed with the exhaust passage 9 being connected to tapered rod 3, the height H1 of exhaust passage 9 is 0.5mm~2mm, the height of exhaust passage 9
Spending H1 is preferably 1mm.The pressure sand ring 10 that limitation molten iron pours into tapered rod 3 is equipped on exhaust passage 9, by the way that exhaust passage is arranged
9 and pressure sand ring 10 be combined be conducive to using die joint row portion gas prevent molten iron from entering blast pit into blast pit, while again.
Pressure sand ring 10 is semicircular structure, and the height of pressure sand ring 10 is 1.5mm, and the height of pressure sand ring 10 is higher than the height of exhaust passage 9
Degree, enables pressure sand ring 10 that molten iron is prevented to enter blast pit, and the width D 1 of pressure sand ring 10 is 3mm.
The utility model solves large-scale dell revolving body casting by the improvement to mould structure and makes because exhaust is bad
At scab major defect the problem of, improve the degree of packing of casting mold, reduce the dosage of tide mould sand, alleviate cleaning difficulty,
Product surface quality is improved, manufacturing cost is reduced.
The above embodiments are only illustrative of the principle and efficacy of the utility model, and not for limitation, this is practical new
Type.Any person skilled in the art can all carry out above-described embodiment under the spirit and scope without prejudice to the utility model
