假塑性流体模型在橡胶冷流道注射硫化机模具改造设计中的应用

Application of pseudoplastic fluid model in the mold modification design of rubber cold runner injection curing press

冷流道模具因为节省材料,可以明显降低材料报废,提高产品质量,目前越来越多的被用在注射式硫化的橡胶产品生产工艺中。其中,冷流道的设计成为整个硫化模具设计的关键,如何能最大限度的设计模具型腔,提高效率,本文采用假塑性流体模型来讨论验证多孔模具的可行性。

Cold runner mold can significantly reduce material waste and improve product quality because of material saving.At present,it is more and more used in the production process of injection vulcanized rubber products.Therefore,the design of cold runner has become the key to the design of the curing mold.How to maximize the design of mold cavity to improve efficiency has become a key point.In this paper,a pseudoplastic fluid model is used to discuss and verify the feasibility of porous die.
