In the development process of new products of diesel engine cylinder block,the sand molds are made firstly by the methods such as sand molding(core)method,digital precision molding technology without mold cutting or inkjet 3D printing molding.Then the molten metal is poured into the sand mold to form the casting.However,the above methods for preparing sand molds have long molding cycles or high manufacturing costs.Therefore,this paper has studied a rapid reshaping method to transform the original sand mold into a new sand mold that can be used again for the production of new cylinder block products,which has reduced the sand mold manufacturing cost by 39.2%in the process of product development of the cylinder block,this method has good promotion and application value.
