バーフロー金型を用いた射出成形機の機能の研究

抄録

In studying the functions of injection molding machines, we performed experiments using a bar flow die, which allowed the weight of molded articles to be varied easily according to the capacitieg of various dies used by injection molding machine users. A functional evaluation was carried out in which measured volume was the signal and the weight of the resin injected into the die was the output. At the same time, referring to studies of machine tools in which power consumption was treated as a basic function, we evaluated power consumption by the injection molding machine, using the weight of the molded article as a signal and electric power consumed in measurement and injection as outputs simultaneously. The gain was shown to be reproducible in verification tests,demonstrating that the two functions are functions of the injection molding machine.
