| Abstract: | Producing the large-scale thin shell part can easily result in defects. It can effectively reduce defect with the correct die-casting process and mould structure design and the mold cavity vacuum. Numerical simulation-assisted method to determine gate and the pouring system , and position of the slag traps and location of the exhaust port provide the basis for proper design mould structure. With rationally determined the exhaust timing and a reasonable die-casting process, the final casting can be qualified. |
