【正文】 模型分流道系統(tǒng)的優(yōu)化由MPI/Flow模型來展示。分流道平衡分析被用來分流道系統(tǒng)體積的優(yōu)化，當使用足夠填充時的平衡填充方式。主要的分析是47, 92%的分流道系統(tǒng)體積的減少輸出。這也減少了材料的成本和周期。在圖31，32中，是填充始時間與冷卻時間的輸出?；谶@些數(shù)據(jù)是在模具沒有制造與修復的前提下，在設(shè)計階段中所必要的。圖31. 填充時間分析圖32. 冷卻時間的分析在想要的流道分析輸出后，基于有限元網(wǎng)格劃分的3D CAD 模型被準備好（圖41）。這個模型被輸入CAM系統(tǒng)然后在CNC機床中制造模具。 CAD 模具裝配7 / 13Design of Injection Mould Using CAEAbstractThe contribution deals with several steps puter simulation application by means of CAE system Moldflow MPI in mould development for mold plastic part. Based on result of simulation design of injection mould is made with help of Pro/Engineer CAD system. Application of the CAE methods is accentuated in the development phase of the product, which redounds to cost reducing on tools and moulds development.Keywords: injection moulding, CAE simulation, Moldflow1 IntroductionOne of the most mon processing methods for 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 pon
