橡胶注射机胶料过滤装置研究

Research on Compound Filtering Device of Rubber Injection Machine

对比分析橡胶注射机模腔内胶料过滤装置与注射单元胶料过滤装置的基本结构、在设计过程中出现的问题及使用优缺点。模腔内胶料过滤装置过滤面积大,通用性强,但拆装维护不便,成本高。注射单元胶料过滤装置拆装维护便捷,但过滤面积受一体式活塞头直径限制,过滤能力有限。应根据实际需求选择过滤装置,对于大型注射机,应优先选择模腔内胶料过滤装置。

The basic structure,problems in design process,and advantages and disadvantages of the compound filtering devices in the mold cavity and injection unit of rubber injection machine were comparatively analyzed.The compound filtering device in the mold cavity had a large filtering area and strong versatility,but it was inconvenient to disassemble and maintain,and the cost was high.The compound filtering device in the injection unit was easy to disassemble and maintain,but the filtration area was limited by the diameter of all-in-one plug head,so the filtration capacity was limited.The selection of filtering device should be made according to the actual needs.For large injection machine,the compound filtering device in the mold cavity was preferred.
