目前我国的型材挤压模具设计水平仍停留在经验设计阶段，模具寿命偏低。为了提高挤压模具的设计水平，实现模具设计的实时化、自动化、科学化与集成化，提出了挤压模具智能CAD新概念，并介绍了其系统构成。
At present, China’s profile extrusion die design level is still stuck in the design stage of experience, die life is low. In order to improve the design level of extrusion die, realize the real-time, automatic, scientific and integration of die design, a new concept of die CAD for extrusion die was put forward and its system structure was introduced.
