【文章內(nèi)容簡介】 ents and whole injection mould to resist clamping and injection pressures?? proper runner, ejection , venting and cooling system?? optimal lifetime.Tasks for injection mould designer are:?? Analyze molded part design considering shape, dimensions, gate location and ejection of part?? define parting plane considering function and appearance of molded part, define drafts in cavity?? determine number of cavities, cavity layout and cavity dimensions considering shrinkage, geometry tolerance, wear of cavity and used injection molding machine ?? select proper design of ejection, cooling and venting system? select material for mould base and other mould ponents considering conditions and load duringinjection molding cycle.? choose tightening of mould on injection molding machine.Nowadays technical drawing of injection molded part is not sufficient to describe plex shapes in 2D drawing. Reason for using 3D CAD model are wide opportunities to exact describe shape of part, easy making of cut views and detail views. More important reason to use 3D CAD model is CAE process simulation of injection molding and mold manufacturing with CAM software. (2) Using 3D CAD model for CAM software has bee integral part of mould manufacturing. (4) CAE process simulation of injection molding is being stepwise integral part of mould manufacturing process. With help of CAE simulation mould designer can test various construction solution of injection mould without need cost a time c
