COUPLED FEA SIMULATION OF THE DEMOULDING PROCEDURE OFINJECTION MOULDED PARTS

摘要

A reasonable design of the injection mould has to guarantee that the moulded part can be demoulded without damaging either the ejection system in the mould or the part In the conventional mould design this damaging occurs at the very end of the development process of the injection mould when it is already assembled. A simulation procedure is presented which enables the mould maker to mechanically layout the demoulding system. It combines a process simulation with a structural analysis and hence maximises the advantage of using CAE.
