| 中文摘要: |
| 介绍航空橡胶波纹管（以下简称波纹管）模具的轻量化设计与制造，其过程如下：在保证波纹管模具使用性能不变的基础上，将波纹管模具的上、下模实体结构变为拓扑网状点阵结构，生成STL（立体光刻）模型；选择CX模具钢，利用金属3D打印和选区激光熔化成型技术快速制造轻量化波纹管模具。模压硫化试验结果表明，采用轻量化波纹管模具制备的波纹管尺寸满足企业标准要求。 |
| 英文摘要: |
| This paper introduces the lightweight design and manufacturing of moulds of aerospace rubber
bellows. In the design process，the solid structure of the upper and lower die was changed into the topological
mesh lattic structure based on ensuring the same performance of the moulds，and then the STL（stereoscopic
lithography ） model was generated. The lightweight moulds was manufactured by metal 3D printing and
selective laser melting forming technology using CX die steel. The results of vulcanization test showed that
the size of aerospace rubber bellows prepared by the lightweight moulds met the requirements of enterprise
standards. |
