【正文】 英文原文 Injection Molding CAE Technology0 IntroductionPlastic products from product design to production including molding plasticproducts design mold design mold manufacturing and injection molding processparameters and several other main areas. The traditional injection mold design mainlyrely on the designers experience while the injection molding process is very plexplastic melt flow properties of different and everchanging products and die structureprocess conditions vary forming various defects mold design often require repeatedtrialmode maintenance mode can be put into production with little of a successfulidentify problems not only to readjust the process parameters or even to modify theplastic products and molds not only timeconsuming and laborious but also reducesproduct development time . The use of injection molding CAE technology in moldmanufacturing prior to simulate injection molding process including filling packingand cooling and the early detection of problems optimize mold design and processconditions set to reduce the number of test mode in order to improve productionefficiency has bee a injection molding technology is an important direction The history of Injection Molding CAE technologyInjection Molding CAE technology is based on plastics processing rheology and heattransfer of the basic theory the melt in the mold cavity in the flow heat transferphysics mathematical model using numerical solution method of constructing thetheory the use of puter visualization technology image visually simulate thedynamics of the actual shape of the melt filling and cooling process an 20th century 60 years the United Kingdom the United States and Canada andother countries of the scholars such as JRPearson United Kingdom JFStevensonAmerica MRKamal Canada and KKWang America etc. to carry out a series ofplastic melt in the moldtype cavity flow and cooling of basic research. At areasonable simplification based on 60 years pleted a onedimensional flow andcooling analysis programs 70 years to plete the twodimensional cooling analysisprograms and 80 years from the injection molding CAE technology has begun totheoretical research into the practical phase launched a threedimensional flow andcooling analysis and the study extended to packing fiber orientation and warpageprediction of molecular and other fields. After 90 years carried out into the flowpacking cooling and stress analysis the whole process of injection molding processesare integrated technologies for the injection mold design provides a reliable guarantee that itsapplication is mold design in the history of a major The role of Injection Molding CAE technologyUsing traditional methods of design of injection mold design success will rely heavilyon the experience of designers but also for plex parts gate position is reasonableor not the location of the exhaust slot settings to determine the location of weld linesand so very difficult.
