Abstract
The invention discloses a novel casting and pouring system for cabin casts of a wind driven generator. The novel casting and pouring system comprises an outer cast moulding sand box, an internal sand box and a base, wherein the internal sand box is arranged in the outer cast moulding sand box; the base is connected to the outer cast moulding sand box in a seal mode; the shapes of the outer cast moulding sand box and the internal sand box are both consistent to that of a cabin of the to-be-manufactured wind driven generator; the upper surfaces of the outer cast moulding sand box and the internal sand box are fixedly connected in a seal mode; resin moulding sand coats the opposite side walls of the outer cast moulding sand box and the internal sand box; a cast moulding cavity is formed between the resin moulding sands; and a horizontal pouring gate for circulation of a metal liquid is also formed on the base, and the cast moulding cavity is communicated with an external metal liquid injection system through the horizontal pouring gate. The casting and pouring system saves materials and labor, and lowers production costs effectively.
Description
Technical field
The present invention relates to casting and pouring processing technique field, relate in particular to the novel casting running gate system of engine rooms of wind power generators foundry goods.
Background technology
Traditional system for casting and pouring generally comprises the top box 5, raising middle flask 6 and the nowel 7 that connect successively from top to bottom, and in sandbox potting resin molding sand, surrounded the foundry goods die cavity of required foundry goods shape by resin bonded sand, then by sprue to casting of molten metal in foundry goods die cavity.But existing wind power casting is large product mostly, such as the foundry goods such as taper support, wheel hub, like this in the time of casting, just need to prepare a casing that volume is very large, but also need to fill a large amount of resin bonded sands, so not only increase production cost, but also wasted a large amount of resources and labour, do not met the energy-saving and cost-reducing demand that country advocates.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of novel casting running gate system of engine rooms of wind power generators foundry goods, this system for casting and pouring not only can improve the quality of product, but also has effectively reduced production cost, energy-saving and cost-reducing.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of novel casting running gate system of engine rooms of wind power generators foundry goods, comprise foundry goods external form sandbox, be arranged in the interior sandbox in described foundry goods external form sandbox and be sealedly attached to the base below described foundry goods external form sandbox, wherein, the shape of described foundry goods external form sandbox and interior sandbox is all consistent with the shape of engine rooms of wind power generators to be processed, the fixed seal connection above of described foundry goods external form sandbox and interior sandbox, the another resin bonded sand that is all coated with in the opposing sidewalls of described foundry goods external form sandbox and interior sandbox, this is to being formed with foundry goods die cavity between resin bonded sand, and on described base, also offer a horizontal running channel for molten metal circulation, described foundry goods die cavity connects by this horizontal running channel and extraneous molten metal injected system.
As a further improvement on the present invention, extraneous molten metal injected system includes a sprue, and described sprue and described horizontal running channel connect.
The invention has the beneficial effects as follows: this system for casting and pouring comprises foundry goods external form sandbox, be arranged in the interior sandbox in described foundry goods external form sandbox and be sealedly attached to the base below described foundry goods external form sandbox, wherein, the shape of described foundry goods external form sandbox and interior sandbox is all consistent with the shape of engine rooms of wind power generators to be processed, the fixed seal connection above of described foundry goods external form sandbox and interior sandbox, the another resin bonded sand that is all coated with in the opposing sidewalls of described foundry goods external form sandbox and interior sandbox, this is to being formed with foundry goods die cavity between resin bonded sand, and on described base, also offer a horizontal running channel for molten metal circulation, described foundry goods die cavity connects by this horizontal running channel and extraneous molten metal injected system.This system for casting and pouring material-saving, saving of labor, reduced production cost effectively.

Detailed description of the invention
The embodiment of the novel casting running gate system to engine rooms of wind power generators foundry goods of the present invention is elaborated with reference to the accompanying drawings.
The novel casting running gate system of a kind of engine rooms of wind power generators foundry goods of the present invention, comprise foundry goods external form sandbox 1, be arranged in the interior sandbox 2 in described foundry goods external form sandbox and be sealedly attached to the base 3 below described foundry goods external form sandbox, wherein, the shape of described foundry goods external form sandbox 1 and interior sandbox 2 is all consistent with the shape of engine rooms of wind power generators to be processed, the fixed seal connection above of described foundry goods external form sandbox 1 and interior sandbox 2, the another resin bonded sand that is all coated with in the opposing sidewalls of described foundry goods external form sandbox and interior sandbox, this is to being formed with foundry goods die cavity between resin bonded sand, and on described base, also offer a horizontal running channel for molten metal circulation, described foundry goods die cavity connects by this horizontal running channel and extraneous molten metal injected system.
In the present embodiment, extraneous molten metal injected system includes a sprue 4, and described sprue and described horizontal running channel connect.
In the present invention, this system for casting and pouring can also be used for casting the foundry goods such as wheel hub, conical supports of wind-driven generator, and the shape of described foundry goods external form sandbox 1 and interior sandbox 2 can change according to the difference of casting structure.
Patent of the present invention not only can be applied in wind-power electricity generation foundry goods industry, can also be applied in the foundry goods of other industry, every relate to the novel casting pouring technology principle that uses in the present invention all within the protection domain of patent of the present invention.
