Research on air quantitative prediction based on mold filling simulation of high pressure die-casting

Air-entrapped is a common defect for high pressure die-casting, so it is critical to discharge the air out of mold cavity as much as possible. This study takes the research on air quantitative prediction technology based mold-filling process. Firstly, the quantitative prediction technology is introduced and the mathematical model based on a simple die casting is established. Secondly, based on HZCAE technology the paper offers calculation module and post-processing module about air quantitative prediction. And then, water simulation is carried out to validate this air-entrapped prediction technology. Finally, combined with a die-casting case, we use the program to calculate its air quantitative prediction based on the simulation result of HZCAE/InteCAST.
