高光无痕挤压模具优化设计

针对模具设计不合理和模腔温度不均匀，分析了型材挤压成型及表面质量的缺陷，提出了挤压模具热冷温控装置方案，介绍了高光无痕挤压模具的结构和优化设计。实验证明快速成型模具能有效清除型材表面条纹，提高型材质量和生产效益。

Optimized Design of High Smooth and No Mark Extrusion Die

According die design no reasonable and die temperature no even, Analyzed defects of aluminium section molding and surface quality, The heat and cold temperature control methods of extrusion die are raised. The good design method and the constitution of high smooth and no mark extrusion die are introduced. Experiment showed the streak on surfaces of profiles can be cleared away effective by the quick molding die design methods. Raise quality of profiles and produce beneficial result.
