Abstract

The invention relates to a method for preventing a shrinkage crack of a casting. The casting is produced by adopting sand mold casting, the method for preventing the shrinkage crack of the casting comprises the following steps that a strength technical standard of a sand mold is adjusted, and the strength technical standard comprises the sand mold tensile strength and the sand mold compressive strength; and a design structure of the sand mold is optimized, the sand mold is designed to be of a structure with a hollow inner cavity, and a plurality of reinforcing ribs are arranged in the hollow inner cavity. According to the method for preventing the shrinkage crack of the casting, the problems that the casting is prone to cracking and having size deviation during production can be effectively solved, so that the sand mold rejection rate of the casting is reduced, the research and development progress of a new product is accelerated, the research and development cost is reduced, and rapiddevelopment of a new product and a new technology is promoted.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to a method for reducing shrinkage cracks of casting sand molds. Background technique [0002] With the continuous update and development of science and technology, the casting of non-ferrous alloys has developed rapidly in recent years, and the update and iteration of new products and new technologies has developed in a straight line, among which the automotive, aviation, and aerospace industries are represented. Due to the rapid development of new products and new technologies, the development time of verification parts is even more urgent. In order to quickly produce samples, most industries choose to use 3D printing sand molds for casting. In the prior art, the 3D printing sand casting method is generally as follows: first, the sand mold modules are designed separately in the 3D software, and then the designed files are transferred to the 3D printer and printed, and then the pri...
