摘要
Abstract
A detailed analysis is conducted on the issues of wear and lack of material issues in the lining block of TH-type molds,and the reasons for the defects are identified.The quality of the mold has a significant impact on the quality of the products,and sand cores are commonly used molds in the casting process.The wear and lack of material in the mold lining block are major causes of defective sand core products.To address these issues,technical improvements are carried out on the design flaws of the mold's sand nozzle.The improved sand core mold with the modified sand nozzle has increased the yield of sand core production and reduced the problem of reduced productivity due to insufficient sand core supply.After six months of trial use and quality control tracking,the modified mold has demonstrated better wear resistance and higher accuracy,resulting in higher quality sand core products.This not only improves the yield of sand core production and reduces the production of waste engine cylinder heads,but also enhances production efficiency and reduces production costs,creating significant economic benefits for the company.关键词
