Abstract: The mould plays a key role in the composite product modeling. In this paper, a cylindrical body composite products for a typical shapes were studied, and designed a composite mold making for metal and resin two kinds of material, which was simple structure, low production cost , in compare with the split mold designed by the metal material, which provides a design ideal for composite mold design workers.

Key words: composite cylinder, split mould of metal, metal-resin combined mould
