1、河南科技大学毕业设计说明书下水管接头注射模具中文摘要塑料制品在人们日常生活及现在工业生产领域中得到日益广泛的应用。随着塑料工业的发展，社会对塑料制品的需求愈来愈大，尤其是建筑材料中各种管道和接头。如今，pvc（聚氯乙烯）已逐步取代铸铁成为一种较为理想的管道制造材料。它与铸铁相比有质量轻，耐腐蚀，寿命长，成本低，生产率高，制造简单等优点。随着房地产业的发展，人们生活水平的提高，作为一种新兴的建筑材料，它有很广泛的应用前景和市场前景。因此本人在指导老师的建议下选择下水管接头注射模具作为毕业设计的题目，锻炼自己独立分析，
2、解决问题的能力。该产品的主要功能是配合接头螺母连接水池和下水管。该产品的成型模具经分析采用两板式斜滑块侧向分型结构，一次成型两个制件，模具在侧向分型的同时完成制件顶出动作。本说明书概述了聚氯乙烯的性能和注射成型工艺，具体的分析了制品结构和成型工艺。并重点分析了两板式斜滑块结构的工作原理，特点及成型该产品的合理性，经济性。关键词：塑料，模具，注射，下水管接头，斜滑块37第页河南科技大学毕业设计说明书MoldPipelineofJointingandSyringingAbstractRecently,theplasti
