Abstract
The utility model relates to a dead head top exhaust device of a sand-prevention air hole, which comprises a casting, wherein a dead head table is arranged above the casting, a dead head jacket is arranged on the dead head table, the top part of the dead head jacket is provided with a boss, a vent hole arranged on the top part of the boss and the air outlet hole of the dead head jacket are staggered, the air outlet hole of the dead head jacket and the vent hole of a sand die are not in the same axis, so that scattered sand falling from the vent hole can be fully gathered on the top part of the dead head jacket, in this way, the purpose of air exhausting is achieved, the effect of sand prevention is also obtained, the manufacturing method is simple, and the dead head top exhaust device can be applicable to the vent holes of all castings.
Description
Technical field
The utility model belongs to casting technology field, relates to a kind of when adding the exhaust passage at casting technique rising head top, as to prevent sand hole exhaust apparatus.
Background technology
At casting field, existing rising head top need be provided with the exhaust passage.General more general method is after moulding is finished, and adopts drill rod or electric drill directly to punch steam vent at sand rising head or riser buss top.Beat the mode of steam vent according to tradition, discharging port surface especially floor sand layer segment is quite coarse, the loose sand that distributes is more, can't depend on the labor cleaning at all, and under the vibration of external environments such as mould turnover and mould assembling or under the gas shock in the pour steel process, residual sand can fall into sand mo(u)ld and cause the foundry goods sand hole from the rising head top.
The utility model content
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of and can enhance productivity, can prevent again the rising head top exhaust apparatus of the sand control pore that the foundry goods sand hole forms.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of rising head top exhaust apparatus of sand control pore, comprise foundry goods, above foundry goods, be provided with the rising head platform, on the rising head platform, riser buss is housed, top at riser buss is provided with boss, is provided with steam vent at the top of boss and the venthole staggered positions of riser buss.
The shape of described boss is identical with riser buss.
The size of described boss is less than the size of riser buss.
The height of described boss is 4-6mm.
The beneficial effects of the utility model are: the venthole of riser buss and the steam vent of sand mo(u)ld be not on same axis, thereby make the loose sand that from steam vent, falls down all accumulate in the riser buss top, both reached the purpose of exhaust, reached the effect of sand control again, its preparation method is simple, can be popularized for the steam vent of all foundry goods.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-steam vent, 2-boss, 3-venthole, 4-riser buss, 5-rising head platform, 6-foundry goods.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Referring to Fig. 1, a kind of rising head top exhaust apparatus of sand control pore, comprise foundry goods 6, above foundry goods 6, be provided with rising head platform 5, riser buss 4 is housed on rising head platform 5, but a boss 2 that size smaller identical with riser buss 4 top shape is installed at the top of the riser buss 4 on mould, and the height of boss is 4-6mm.After having made type, steam vent 1 is punched, knock in the riser buss 4 of accomplishing fluently venthole 3 in the sand mo(u)ld die cavity fixing then.
In the present embodiment, increase the boss 2 of about 5mm at riser buss 4 mould tops, at the top of boss 2 and venthole 3 staggered positions of riser buss 4 steam vent 1 is set then; After the moulding, the sand mo(u)ld steam vent is punched, and then the venthole on the riser buss 43 is punched, put into sand mo(u)ld and fix.
In the present embodiment, increase the boss 2 of about 5mm at riser buss 4 mould tops, at the top of boss 2 and venthole 3 staggered positions of riser buss 4 steam vent 1 is set then; After the moulding, sand mo(u)ld steam vent 1 is punched, and then the venthole on the riser buss 43 is punched, put into sand mo(u)ld and fix.The steam vent 1 of the venthole 3 of riser buss 4 and sand mo(u)ld is not just on same axis like this, thereby make the loose sand that from steam vent 1, falls down all accumulate in riser buss 4 tops, and can as traditional approach, directly not fall into the die cavity from steam vent 1, thereby produce foundry goods sand hole defective, so both reach the purpose of exhaust, reached the effect of sand control again.
