从中学习到了许多模具设计的知识并对课本上所学知识有了进一步的理解，理论联系实际，综合运用了所学的模具、机械、力学、制图等方面的相关知识。

此外，本文还介绍了注塑模国外的现状，我国模具产业与国外的差距以及模具的发展前景、未来趋势。

Pro-Engineer3.0 and CAD 2007 is applied to the whole design to complete the whole of the mould design ,including the mold assembly drawing ,the three dimensional figure and the floor plan of parts。

This work makes the designer know more about the skills of mould design and deepen the knowledge he studied in the University. Theory with practice ，integrated use of the knowledge learned molds, machinery, mechanics, graphics and other aspects.In addition ，this paper also introduced the present situation of the injection mold at home and abroad ，the gap between the mould industry in China and the mould industry abroad ，prospects for development of the mould industry and the future trend of mould industry。
