Abstract
The utility model discloses a novel casting and pouring system of wind turbine hub castings. The system comprises a casting outer molding sand box, an inner sand box and a base, wherein the inner sand box is arranged in the casting outer molding sand box; the base is hermetically connected at the bottom of the casting outer molding sand box; the shapes of the casting outer molding sand box and the inner sand box are consistent with the shape of a wind turbine hub to be processed; the casting outer molding sand box is fixedly and hermetically connected with the top of the inner sand box; the relative side walls of the casting outer molding sand box and inner sand box are coated by resin molding sands; a casting mold cavity is formed between the resin molding sands; a horizontal runner for molten metal to flow is also formed on the base; and the casting mold cavity is communicated with an outside molten metal injection system via the horizontal runner. The casting and pouring system saves materials and labor, effectively reduces the production cost and meets the requirements of energy conservation and consumption reduction advocated by the state.
Description
Technical field
The utility model relates to the casting and pouring processing technique field, relates in particular to the novel casting running gate system of hub of wind power generator foundry goods.
Background technology
Traditional system for casting and pouring generally comprises top box 5, raising middle flask 6 and the nowel 7 that connects successively from top to bottom, and in sandbox the potting resin molding sand, surround the foundry goods die cavity of required foundry goods shape by resin bonded sand, then by sprue casting of molten metal in the foundry goods die cavity.But existing wind-powered electricity generation foundry goods is large product mostly, such as foundry goods such as taper support, cabins, like this when casting, just need to prepare the casing that volume is very big, 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 defective, the utility model provides a kind of novel casting running gate system of hub of wind power generator foundry goods, and this system for casting and pouring not only can improve the quality of product, but also has reduced production cost effectively, and is energy-saving and cost-reducing.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of novel casting running gate system of hub of wind power generator foundry goods, comprise foundry goods external form sandbox, be arranged in the interior sandbox in the described foundry goods external form sandbox and be sealedly attached to base below the 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 hub of wind power generator to be processed, the top fixed seal connection of described foundry goods external form sandbox and interior sandbox, on the opposing sidewalls of described foundry goods external form sandbox and interior sandbox, all be coated with resin bonded sand in addition, this is to being formed with the foundry goods die cavity between the resin bonded sand, and on described base, also offering a horizontal running channel for the molten metal circulation, described foundry goods die cavity connects by this horizontal running channel and extraneous molten metal injected system.
As further improvement of the utility model, extraneous molten metal injected system includes a sprue, and described sprue and described horizontal running channel connect.
The beneficial effects of the utility model are: this system for casting and pouring comprises foundry goods external form sandbox, be arranged in the interior sandbox in the described foundry goods external form sandbox and be sealedly attached to base below the 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 hub of wind power generator to be processed, the top fixed seal connection of described foundry goods external form sandbox and interior sandbox, on the opposing sidewalls of described foundry goods external form sandbox and interior sandbox, all be coated with resin bonded sand in addition, this is to being formed with the foundry goods die cavity between the resin bonded sand, and on described base, also offering a horizontal running channel for the 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 have reduced production cost effectively, meet the energy-saving and cost-reducing demand that country advocates.

The specific embodiment
Embodiment to the novel casting running gate system of hub of wind power generator foundry goods of the present utility model is elaborated with reference to the accompanying drawings.
The novel casting running gate system of a kind of hub of wind power generator foundry goods of the present utility model, comprise foundry goods external form sandbox 1, be arranged in the interior sandbox 2 in the described foundry goods external form sandbox and be sealedly attached to base 3 below the 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 hub of wind power generator to be processed, described foundry goods external form sandbox 1 and interior sandbox 2 top by the top box fixed seal connection, on the opposing sidewalls of described foundry goods external form sandbox and interior sandbox, all be coated with resin bonded sand in addition, this is to being formed with the foundry goods die cavity between the resin bonded sand, and on described base, also offering a horizontal running channel for the 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 utility model, this system for casting and pouring can also be for foundry goods such as the cabin that casts wind-driven generator, taper supports, and the shape of described foundry goods external form sandbox 1 and interior sandbox 2 can change according to the different of casting structure.
The utility model patent not only can be applied in the 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 used in the utility model all within the protection domain of the utility model patent.
