Problems solved by technology

However, in the actual casting process, due to the different shapes, sizes, volumes, and lengths of the cast products, in order to reduce the cost of the sand box, several fixed models of sand boxes are often used to cast various types of parts, generally not for each A separate sand box is manufactured for a part, which will lead to the use of a large sand box for the casting of some small parts. In order to improve the quality of castings, many of them now use self-setting resin sand for casting, and the cost of self-setting resin sand High, if a large sand box is used to cast small parts, it will lead to a lot of waste of self-setting resin sand, which will increase the cost of casting

Abstract

The invention relates to the technical field of foundry equipment, and in particular discloses a combined sand box structure, which includes a number of shrouds, each of which is connected end to end to form a complete sand box cavity wall, and one of the two adjacent shrouds The two connecting ends of the board are provided with pin holes and connecting grooves passing through the pin holes, and the two connecting ends of the other panel are provided with connecting bosses and connecting holes passing through the connecting bosses, and the connecting bosses are snapped into the connecting grooves and Connected by positioning pins, the connecting end of the coaming is also provided with threaded holes communicating with the pin hole and the connecting hole. There are several through holes on the side of the positioning pins. After the two adjacent coamings are connected, the through holes on the positioning pins The position is aligned with the threaded hole, the threaded hole is provided with a bolt, and one end of the positioning pin is provided with a rotating adjustment handle. Therefore, the present invention has the beneficial effects of being able to adjust the size of the sand box according to the size of the casting, reducing the amount of sand used, and reducing the casting cost.

Description

technical field [0001] The invention relates to the technical field of casting equipment, in particular to a combined sand box structure. Background technique [0002] In the casting production process, the sand box is an indispensable tooling. Reasonable sand box structure and size play a great role in obtaining high-quality castings and improving casting production efficiency. However, in the actual casting process, due to the different shapes, sizes, volumes, and lengths of the cast products, in order to reduce the cost of the sand box, several fixed models of sand boxes are often used to cast various types of parts, generally not for each A separate sand box is manufactured for a part, which will lead to the use of a large sand box for the casting of some small parts. In order to improve the quality of castings, many of them now use self-setting resin sand for casting, and the cost of self-setting resin sand High, if a large sand box is used to cast small parts, it will...
