【正文】 r plastics is injection moulding. The major advantages of the process include its versatility in moulding a wide range of products, the ease with which automation can be introduced, the possibility of high production rates and the manufacture of articles with close tolerances.Production of injection molded parts is in progress with injection molding machine and injection mould. This process is running in relatively short cycles pared to other production methods for plex shape parts. Standard demands on injection mould are:?? High accuracy and cavity surface finish?? Maximal stiffness and strength of mould ponents 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
