Abstract：According to the structural characteristics of TDV100 cylinder block,the casting difficulties are analyzed and the casting process is designed.Triethylamine cold box method was used for core making and fiiran resin sand molding;The gating system is designed as the middle injection type,and its section is semi closed.The exhaust rod and exhaust piece are respectively designed on the oil pan mounting surface and the bearing bush surface;In the aspect of smelting,RE inoculant and Si-Ba inoculant were used for compound inoculation,which effectively improved the mechanical properties of castings;The results show that the mechanical properties and graphite morphology of the cylinder block meet the requirements,no defects are found on the surface and inside of the casting,and the quality of the cylinder block is good.
