MOULD DESIGN OF THE COMPOSITE LAUNCH BOX

Abstract

Abstract: This paper uses the unique mould design to slove the demoulding problem of the launch box. According to the technical features of composite launch box′s large size and high precision,combined with the process characteristics of integral SCRIMP forming and demoulding, through the finite element analysis, the steel mould with arch door ribs and web ribs was designed and optimized. Using the CAD/CAE technology to design the launch box mould and taking variable fillet to solve the problem of demoulding, the prototype of the launch box was successfully manufactured and it had met the requirements of product design.Through those works, a feasible technological plan of the mould design technology for compsite products with large long axis structure was explored.

Key words: composite, launch box, mould design, variable fillet design
