Development and Verification of Shell Low Pressure Die Casting Process Based on Sand Mould 3D Printing Technology
The shell casting has characteristics of complex internal cavity and thin-walled structure,therefore,it is not only difficult to adopt the traditional method of molding,but also from the mould design to the development and verification of the overall casting process,has characteristics of long cycle and low efficiency.Thus,the production cost is increased.Based on the advantages of 3D sand printing technology,this experiment adopted the shape design scheme for the shell pouring system to realize the integrated structure forming manufacturing of cavity and blade.Combined with the numerical simulation calculation and analysis,the pouring process was optimized,and the pouring trial production and casting detection were carried out.The results showed that the 3D sand printing integral forming process could achieve the short period,low cost and high precision manufacturing of complex structure shell,and realize the rapid manufacturing of process samples.
