Description

Technical Field

[0001] This utility model belongs to the technical field of molding sand recovery devices, specifically a precision casting molding sand recovery device that is easy to feed. Background Technology

[0002] Molding sand is a material used to make sand molds. It is usually made by mixing foundry sand, molding sand binder, and additives in a certain proportion. Its main function is to form the shape of the casting during the casting process and withstand the impact of high-temperature molten metal. After the molding sand is used up, it needs to be recycled.

[0003] Existing molding sand recycling devices mainly include a guide frame, a fixing plate, a collection frame, and a base. During use, the guide frame guides the molding sand into the collection frame, thereby enabling auxiliary recycling of the used molding sand.

[0004] However, in actual use, molding sand may agglomerate into lumps. The lumpy molding sand will affect subsequent use and plasticity. Therefore, it needs to be screened after recycling and then collected and processed separately, which is very time-consuming and labor-intensive. Utility Model Content
