摘要：
The mold temperature field is an important factor to affect the solidification of liquid aluminum in the low pressure die casting process of aluminum wheels. As the main cooling method of casting die, the influence mechanism of water cooling on mold temperature field is still unclear and needs to be further studied. In this paper, the edge die water cooling module of aluminum wheel casting die was used as the research object, and the water cooling experiments was designed to study the influence of water cooling on mold temperature. The flow state of cooling water was analyzed by ProCAST and ANSYS, and the software inverse solution was carried out based on the measured temperature data. The numerical model of interface heat transfer was established based on Beck nonlinear estimation method. In order to provide data support for the simulation and validation of low pressure die casting of aluminum wheels, a comparative analysis of the two solution methods and forward solving were used to verify the accuracy of the two solution methods. It is expected to obtain the real heat transfer coefficient between the cooling water and the mold as well as revealing its heat transfer behavior and mechanism. © 2024 Central South University of Technology.
