Abstract: The defects such as rich glue, poor adhesive, bubble, delamination and other defects are easy to occur in the single-mode and rubber-bag moulding for composite products with small radius of curvature. A simple demoulding mechanism is designed to solve the problem of loading and unloading after the rubber-bag moulding of local punch die, which has deep embedding depth and less striping Angle. The problem of positioning and clamping of local punch die in manufacture and repair is solved by using special fixture positioning and machining on the numerical control machine tool. Therefore, the demoulding mechanism can solve all kinds of problems in the forming process of rubber-bag moulding for the composite material products with local small radius of curvature.
