Casting and gating system for conical support castings of wind turbines

Abstract

The invention discloses a novel casting and pouring system for a conical support casting of a wind driven generator. 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 the to-be processed conical support of the wind driven generator; the casting outer molding sand box is fixedly and hermetically connected with the top of the inner sand box; the opposite 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 pouring gate for circulation of molten metal is also formed on the base; and the casting mold cavity is communicated with an outside molten metal injection system via the horizontal pouring gate. 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 [0001] The invention relates to the technical field of casting and pouring processing, in particular to a casting and pouring system for tapered support castings of wind power generators. Background technique [0002] The traditional casting pouring system generally includes an upper box 5, a middle box 6 and a lower box 7 connected sequentially from top to bottom, and resin molding sand is filled in the sand box, and the casting cavity of the required casting shape is surrounded by the resin molding sand, and then The molten metal is poured into the casting cavity through the sprue. However, most of the existing wind power castings are large-scale products, such as engine room, wheel hub and other castings, so when casting, it is necessary to prepare a large box, and also need to fill a large amount of resin sand, which not only increases the production cost, Moreover, a large amount of resources and labor are wasted, which does not meet the needs of energy...

AI Technical Summary

Problems solved by technology

However, most of the existing wind power castings are large-scale products, such as castings such as nacelles and hubs. In this way, a large box needs to be prepared when casting, and a large amount of resin sand needs to be filled, which not only increases the production cost, but also increases the production cost. And it also wastes a lot of resources and labor, which does not meet the needs of energy saving and consumption reduction advocated by the state.
