Sand-saving type sand box for manufacturing high-strength sand mould

Abstract

The invention relates to a sand-saving type sand box for manufacturing a high-strength sand mould. The sand-saving type sand box comprises an upper box body, a lower box body and a sand box locking mechanism, wherein ports in the top end of the upper box body and the bottom end of the lower box body are opened; core ports are formed in the side surfaces of the upper box body and the lower box body; arc-shaped plates are arranged in the upper box body and the lower box body; concave surfaces of the arc-shaped plates face to the centers of the box bodies; two sides of each arc-shaped plate are fixedly connected with inner walls of two sides of each box body; one end of each of the arc-shaped plates is aligned to the ports of the box bodies and connected with connecting plates; two ends of each connecting plate are fixedly connected with the sidewalls on the two sides of each box body; strip-shaped keels are arranged on the concave surfaces of the arc-shaped plates; sand baffle plates are arranged at the side edges of the core ports; and the sand baffle plates are connected to the sidewalls of the box bodies by a plurality of fixing sheets. By adopting of the sand-saving type sand box for manufacturing the high-strength sand mould, the weight of the sand box can be reduced, the sand leakage of the sand box can be prevented, and the production efficiency in casting process can be effectively improved.

Description

technical field [0001] The invention relates to a casting sand box, in particular to a sand-saving sand box used for manufacturing high-strength sand molds. Background technique [0002] Casting is an earlier metal thermal processing technology mastered by humans. It has a history of 6,000 years. Casting refers to melting solid metal into liquid and pouring it into a mold of a specific shape. After it is solidified and formed, it is obtained after cleaning. The process of castings with predetermined shape, size and performance. The sand box is commonly used in the casting process. The sand box is a part of the mold and is mainly used to accommodate and support the sand mold. The traditional sand box requires a large amount of sand filling, so that the sand The weight of the box becomes larger, and it is inconvenient to move, and the sand core head at the core mouth of the sand box is easy to collide with the sand box, resulting in damage to the core head. When the gap betwee...

The process of castings with predetermined shape, size and performance. The sand box is commonly used in the casting process. The sand box is a part of the mold and is mainly used to accommodate and support the sand mold. The traditional sand box requires a large amount of sand filling, so that the sand The weight of the box becomes larger, and it is inconvenient to move, and the sand core head at the core mouth of the sand box is easy to collide with the sand box, resulting in damage to the core head. When the gap between the core head and the sand box is too large, it will cause the sand box to leak sand. Sand mold deformation affects sand mold and casting quality
