Abstract
A pouring device for the hub casing of a wind driven generator comprises a straight pouring runner provided with a melted iron feeding end, a cross pouring runner and an inner pouring runner. The straight pouring runner is vertical to the cross pouring runner and communicated with the cross pouring runner. The cross pouring runner is communicated with the inner pouring runner. The inner pouring runner is disc-shaped, the inner pouring runner is arranged in the middle of the bottom surface of the lower end of the molding cavity of the hub casing, a circumferential boss is arranged on the disc-shaped inner pouring runner in a position near the outer edge, and the connecting part of the disc-shaped inner pouring runner with the bottom surface of the lower end of the molding cavity of the hub casing is arranged on the outer edge of a round hole of a main bearing at the lower end of the molding cavity of the hub casing. The utility model has the advantages that as the pouring device adopts the bottom injection type pouring system, the cross section area of the straight pouring runner, the cross pouring runner and the inner pouring runner is limited and gradually increased or reduced by the structure of the inner pouring runner on the bottom surface of the molding cavity, melted iron can uniformly reach all parts of the molding cavity, and sand washing defect can be overcome; the structure is also favorable for the flotation of residue type impurities in the melted iron and air bubbles.
Description
Technical field
The utility model relates to a kind of apparatus for pouring, specifically is a kind of apparatus for pouring of hub of wind power generator foundry goods.
Background technology
Along with the needs of progress of science and technology and industrial development, the more and more wider model of the application of heavy castings, demand is also increasing.Applicant unit has accepted the cast task of hub of wind power generator foundry goods recently, 8 tons of the whole substances of this foundry goods, appearance and size is 2212mm * 2734mm * 2368mm, and proposed shrinkage cavity, shrinkage porosite that foundry goods inside must not influential use, be mingled with, the inherent quality requirement of defective such as air gap, crackle.Finish the cast of this type of foundry goods, the structure of apparatus for pouring is particularly important, if adopt traditional apparatus for pouring, obviously is to meet the requirements of.This is because traditional normally closed and open dual mode of apparatus for pouring: the sectional area of the sprue of closed apparatus for pouring, cross gate, ingate diminishes gradually, the molten metal flow velocity is fast, turbulent flow is serious, and scour cast causes volume gas and inclusion defect easily; The sectional area of the sprue of open apparatus for pouring, cross gate, ingate is to enlarge gradually, when causing liquid metal filling, in running channel, there is very air gaps, gas and molten metal interact and form oxide-film, gas and oxide-film are involved in the molten metal, become crackle and shrinkage porosite source, make foundry goods be easy to generate crackle and shrinkage defect.Therefore, need look for another way, design is fit to the apparatus for pouring of hub of wind power generator foundry goods more.
The utility model content
Technical problem to be solved in the utility model is, a kind of apparatus for pouring of hub of wind power generator foundry goods is provided, satisfy in the foundry goods must not influential use shrinkage cavity, shrinkage porosite, be mingled with, the inherent quality requirement of defective such as air gap, crackle.
For solving the problems of the technologies described above, the apparatus for pouring of a kind of hub of wind power generator foundry goods that the utility model provides comprises and is provided with the into sprue of iron liquid end, cross gate and ingate, described sprue communicates perpendicular to cross gate and with cross gate, described cross gate communicates with ingate, described ingate is discoid, described ingate is positioned at wheel hub casts die cavity lower end bottom surface central authorities, described discoid ingate is being provided with circumferential boss near the outer rim place, and described discoid ingate is positioned at the outer rim place of taking turns hub casts die cavity lower end base bearing circular hole with the connecting portion of wheel bottom surface, hub casts die cavity lower end.
After adopting above structure, the apparatus for pouring of a kind of hub of wind power generator foundry goods of the utility model compared with prior art has the following advantages:
Because this apparatus for pouring is to have adopted bottom gating, by being located at the discoid ingate structure of die cavity bottom surface, the sectional area that not merely limits sprue, cross gate, ingate increases gradually or reduces gradually, make molten iron can balancedly arrive each place of beginning to speak, can prevent the sand washing defective, and help the come-up of slag class impurity and bubble in the molten iron.
Described sprue comprises first sprue and second sprue, described cross gate communicates between first sprue and second sprue and with both, the disc centre of described discoid ingate communicates with the lower end of second sprue, this structure can change the position of sprue according to the needs of actual conditions, makes the design of running channel more reasonable.
Be provided with filter in the described cross gate.
Described filter is a filter.
Described filter is for filtering the loam core.
Above filtration helps further stopping slag class impurity.
