摘要
利用Moldflow软件模拟分析了一模两腔PET/PEN瓶坯的注射成型过程,预测塑件成型过程中可能出现的缺陷,优化冷却水道直径、布局和浇注系统尺寸,提出优化的注射成型方案,然后利用注塑机和PET/PEN瓶坯模具注射成型高质量的瓶坯,再利用吹瓶机等设备拉伸-吹塑成型PET/PEN瓶,这样可确保成型瓶子的厚度均匀分布,以生产合格的PET/PEN瓶。
The Moldflow software was used to analyze the injection molding process of a 2-cavity hot runner injection mould for PET/PEN bottle-blank. The mold filling, flowing and cooling processes were visually simulated and the parameters under the conditions of the molding process were obtained. It predicted the potential defects of plastic parts during forming process. The aim was to optimize the cooling channels＇ diameter,layout and gating system size to propose a better injection scheme;then high-quality bottle-blank was to be injected and finally PET/PEN bottle was made through stretch-blow molding process. Thus it could ensure the even-distributed thickness of the bottle and make it a qualified bottle.
