Abstract: At present, practical courses have become important courses for engineering majors, among which casting practice course is an important part of metalworking practice course. However, in the existing casting practice teaching, there are some problems, such as high teaching cost and poor acceptance of students. In order to modernize and digitize the casting teaching course, reduce energy consumption and unnecessary waste in teaching, we can develop a set of virtual casting teaching system with the help of virtual reality technology, that is, Unity3D engine and professional casting software (ProCAST), and carry it out in the mode of combining virtual simulation teaching with actual teaching. The results of the questionnaire show that more than 90% of the students agree with this teaching method. After classroom simulation, the learning efficiency and enthusiasm of the students are significantly improved. This research has reference significance for green casting and casting teaching research in colleges and universities.
