Application of Sand Mold Printing Technology in the Development Stage of Inlet Manifold
With the rapid development of sand 3D printing technology,the problem of sand mold and sand core manufacturing of some complex structural parts has been solved.Based on the research and development of aluminum alloy intake pipe castings,this paper analyzed the complex structure,process design and solidification process simulation of the products,optimized the process plan and parameters,combined with the cold iron and vacuum pressure solidification measures,and quickly produced qualified castings through 3D printing sand mold,reducing the cost of mold manufacturing and modification,shortening the development and trial production cycle,and providing a reference for the rapid manufacturing of similar products.
