Hot Runner Injection Mold Structure Design And Simulation Of Temperature Field,

Hot runner system is a special structure component in injection molding,It can be seen as a extention of injection molding machine. The function of hot runner is send fusing thermalplastic material to mould in heating and thermal retardation environment. Compared to traditional cold runner system,moulds which use hot runner system have some excellence such as high efficiency,good quality and save material and so on. So hot runner system will be used more and more widely in our Country in the future.Hot runner system was rise up early in foreign Countries. And they have acquired many research harvests. There are about 70% to 80% corporations use hot runner system in foreign Countries, and they have get good economic benefit from this. It's much later for our Country to start study hot runner system than foreign Countries,and the technology in our Country is not as good as foreign Countries. Most of our corporations who use hot runner system usually get technology from abroad. As the widely use of hot runner system in our country, More and more people will start to study hot runner system.This text have carry through systemic study about design and use problems of hot runner system in the basic of a great of dates and real produce. By the assist of computer I acquire the rule and conclusion to guide produce. The principle of choose hot runner system is summarized in the article. The structure of hot runner system is right designed, include runners,gates,mainflod and nozzles. Mathematical model and the equations of temprature pattern is set up,and use these equations I acquire some important parameter. At last I calculate and program the hot runner system temprature pattern by MatLab and get the distributing instance of temprature pattern then analysised the simulate results.There are little literatures about hot runner system in our Country ,most of our design are base on experience. This article use computer to ration analyse Hot runner system, avoid blindness when design. While write this article,the autor pay much attention to combine with realistic. Both graphs and acounts are in relation to real produce, so the results of simulation have important reference value for technician design and use hot runner system in real life.
