Abstract: This paper describes a virtual reality technology, designs a virtual reality system for mould teaching. The teaching system is customized for mould assembly and try-out. It is designed in accordance with the working conditions and operation requirements of the mould assembly process, and ensures the friendliness and stability.A database for assembly and try-out of the large covering parts is built. Users can take efficient and accurate implementation of the design concept in the process of operation based on virtual reality environment, and can get rid of the issue that have idea but can’t be realized in conventional CAD software quickly. If this system is applied to the teaching system, students can quickly acquire relevant knowledge and increase their interest, which fundamentally solves the boring of mould teaching.

Key words: virtual reality, mould assembly, mould teaching, Unity 3D, auto mould
