非回转体复合材料壳结构件模具设计方案的探讨

Mould Design Solution for Non-rotation Composite Shell Structures

本文结合应用实例介绍了一种整体成型非回转体复合材料壳结构模具方案。结构形式复杂的壳结构整体成型方式可以避免后期装配所带来的尺寸偏差和其他影响质量的不确定因素。通过模具的型腔尺寸来保证厚度,设计模具时则可以不考虑各型面受力的先后顺序,只考虑各型面的空间几何形状。不同的非回转体壳结构在保证最终成型压力不变的前提下,针对具体情况对加压方式和顺序作不同的改变,可以使模具的设计、加工、产品的成型操作都得到简化。

This paper introduced a mould design solution for non- rotation composite shell structures with practical example. Complex shell structures are molded in whole - form process to avoid the dimension error and other instable quality in the post as- sembles. Mould cavity size can assure thickness, the load sequence of all faces is not taken into account except for geometry shape. The different non- rotation shell structures can make mould design, machining, product molding operation simpler under changing pressure methods and sequence according to the specific condition.
