Description

Tool auxiliary tool combined sand box for large castings

Technical Field

The utility model relates to a tool auxiliary tool combined sand box for a large casting, and belongs to the technical field of cast steel in the metallurgical industry.

Background

The large casting has the characteristics of large outline size, complex shape and small required quantity. The production capacity of the large castings is small in China, and each manufacturer hardly produces a special sand box matched with the large castings. Most manufacturers with unsuitable casting sizes adopt pit modeling, the pit modeling is troublesome in operation, the cost is increased, the rotation of pit positions is slow, and the production efficiency is low; if a special sand box is matched for a certain product or a large sand box is adopted to produce small castings, cost waste is easy to cause. Therefore, whichever mode is adopted, the cost waste is caused, the operation is troublesome, the rotation of pits is affected, and the production efficiency is reduced.

Disclosure of Invention

The utility model aims to provide a tool auxiliary tool combined sand box for a large casting, which can be freely matched with a required size when the large casting is molded, and solves the problems in the prior art.

The technical scheme of the utility model is as follows:

the utility model provides a large-scale foundry goods's frock assistance utensil combination sand box, this combination sand box is the rectangle structure that is made up by four sides sand box wall, and the sand box wall on each side is one or more, links together through the welt between the sand box wall on same side, links together through the connecting plate between the sand box wall between two adjacent sides; the sand box wall is provided with a hanging handle flange table, a reinforcing rib, an air outlet hole and an assembly hole matched with the connecting plate and the lining plate.

And a hanging handle hole penetrating through the wall of the sandbox is formed in the hanging handle flange table.

The sandbox wall is rectangular, one surface of the sandbox wall is a plane, the other surface of the sandbox wall is a concave surface, and the hanging flange table and the reinforcing ribs are arranged in the concave surface of the sandbox wall.

The reinforcing ribs are arranged in a cross shape by taking the hanging flange platform as an intersection point.

The lining board is rectangular, and the length of the lining board is the same as the width of the sandbox wall.

The connecting plate is of a right triangle structure.

The middle of the connecting plate is of a hollow structure.

The beneficial effects of the utility model are as follows: the sand box can be used in molding of various large castings, can be matched with the required size freely, is simple to operate, meets the production requirement, improves the production efficiency and reduces the production cost.
