酒瓶大官帽上盖注塑工艺分析与模具设计
摘要
随着社会的发展与资源的消耗,塑料制品的应用范围变得越来越广。塑料成型技术在形势的发展下,各种成型方法也脱颖而出被大家广泛应用。注塑成型工艺是塑料制品加工中非常重要技术类型,大多数行业的塑料件加工均需要注塑成型工艺来完成,且所涉及的行业及领域甚广。然而,由于制品问题与模具系统设计的一些不合理,在现今社会快速生产要求下,使用CAE软件解决了各项问题,提高了模具质量,加快了效率,节约了成本。
我设计的制品为酒瓶大官帽上盖模具设计,使用材料为ABS。首先我对零件结构进行了分析,确定零件形状与大小及分模形式。接着,我使用Pro/e完成零件图、零件型腔图、三维模架图,使用CAD将三维图结构改为二维工程图。本文主要介绍了对塑料性能、结构工艺、技术要求进行分析,根据零件决定模具结构、型腔数量以及注塑机选择,最后详细设计了模架上的各种结构。最终进行模具制品分析,完善不足之处。
