Abstract
The utility model discloses a pouring device for a cabin cast of a wind driven generator, which comprises a direct gate provided with an outer sprue, a cross gate and a sprue. The pouring device is characterized in that the direct gate comprises two first direct gates (1) and two second direct gates (2); the cross gate comprises two first cross gates (4) and two second cross gates (5); the sprue comprises over three porcelain tube gates (3); the second cross gates (5) are positioned on two sides of a cabin cast cavity and have U shapes approximately vertical to the lateral axial surfaces of the cabin cast cavity; the first direct gates (1) are communicated with the second cross gates (5) through one corresponding first cross gate (4) and one corresponding second direct gate (3) in turn respectively; and one end of each of all the porcelain tube gates (3) is communicated with the second cross gates (5), and the other end of each of all the porcelain tube gates (3) is communicated with three parts of the cabin cast cavity. The pouring device is difficult to produce slag inclusion and pores, meanwhile reduces the scouring of molten iron to the cast, and reduces the pore shrinkage and loosening probability.
Description
Technical field
The utility model relates to the spheroidal graphite cast-iron apparatus for pouring, specifically is a kind of apparatus for pouring of engine rooms of wind power generators foundry goods.
Background technology
Wind-driven generator is to be the dynamic power machine of mechanical power with wind energy transformation, and wind energy more and more causes people's retry as reproducible, free of contamination natural energy resources, and the product quality to big motor requires also more and more higher simultaneously.As shown in Figure 1, engine rooms of wind power generators is a key component of wind-driven generator, its structure comprises three faces on body and the body, it is spindle face, the side shaft face, the hatch face, its appearance and size is 3700mm * 3330mm * 2880mm, the cast of general at present employing spheroidal graphite cast-iron forms, conventional apparatus for pouring comprises sprue, cross gate, cast gate, sprue communicates with cross gate, and cross gate communicates with cast gate, and iron liquid passes through sprue successively, cross gate, cast gate enters casting mold, but because it is heavy castings, single sprue with routine, cross gate, cast gate can't reach quality requirement, and molten iron is easy to produce casting flaw, promptly produces slag inclusion, pore, simultaneously when cast, molten iron is also relatively more serious to washing away of casting mold, the sand washing defective may occur, thereby increase shrinkage cavity greatly, the probability that shrinkage porosite forms.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of difficult generation slag inclusion, pore to reduce the apparatus for pouring that wash away and reduce the engine rooms of wind power generators foundry goods of shrinkage cavity, shrinkage porosite probability of molten iron to casting mold simultaneously.
The technical solution of the utility model is, a kind of apparatus for pouring with engine rooms of wind power generators foundry goods of following structure is provided, comprise the sprue, cross gate, the cast gate that are provided with pouring basin, described sprue comprises two first sprues, two second sprues, and described cross gate comprises two first cross gates and one second cross gate; Described cast gate is three above porcelain tube running channels, described second cross gate is positioned at the both sides of casting cabin casts die cavity and is the U-shaped of the side shaft face of approximate vertical and casting cabin casts die cavity, and described first sprue is communicated with second cross gate by corresponding one first cross gate and one second sprue respectively successively; All porcelain tube running channel one ends are communicated with second cross gate, its other end is communicated with three parts of casting cabin casts die cavity, wherein a part is positioned at the side shaft face bottom of casting cabin casts die cavity, and all the other two parts lay respectively at the inclined-plane of hatch face of both sides of casting cabin casts die cavity and the bottom of die cavity.
After adopting above structure, the utility model compared with prior art, have the following advantages: because this apparatus for pouring is to adopt bottom gating, iron liquid converges to second cross gate by two first sprues and first cross gate, enter into the cast gate that communicates with the die cavity of casting cabin casts by three above porcelain tube running channels again, make the molten iron can be from each place that reaches casting mold of bottom equilibrium, help slag class magazine and bubble floating in the molten iron, be difficult for to produce slag inclusion, pore, reduce molten iron washing away and reduce shrinkage cavity, shrinkage porosite probability simultaneously casting mold.
As improvement, the cross section of described second cross gate is trapezoidal.Just second cross gate is tubaeform, helps weakening high temperature liquid iron to the washing away of casting mold, and can prevent the sand washing defective, also helps pushing off the slag.
As improvement, described first cross gate also is provided with filter cloth, is used to filter molten iron and stops slag class impurity.
As improvement, all porcelain tube running channels are equipped with filter block with the second cross gate place of connection, are used for filtering molten iron once more and stop slag class impurity.
As improvement, the quantity of described porcelain tube running channel is 32, further makes each place of the arrival die cavity of molten iron equilibrium.
