1、本科生毕业设计(论文)摘要熔模铸造是一种净成形工艺,其所生产的铸件精密,复杂,接近于零件最后的形状,可不经加工直接使用或经很少加工后使用。本论文介绍了熔模铸造业的发展现状、优点并应用模具CAD/CAM技术来完成零件(40336706AB)熔模模具设计,模具CAD/CAM是改造传统模具生产方式的关键技术,是一项高科技、高效益的系统工种。它以计算机软件的形式,为用户提供一种有效的辅助工具,使工种技术人员能借助于计算机对产品模具结构、成形工艺、数控加工及成本等进行设计和优化。论文中首先详细阐述了模具设计的基础知识和设计规则,并对壳体零件(4
2、0336706AB)熔模模具进行分析,确定了设计方案;其次,论文介绍了基于Pro/Engineer软件的壳体零件(40336706AB)熔模模具的设计,包括建立模具参考模型,设计模具的分型面、分割体积块、模具浇注系统,最终完成零件模具设计;再次,论文给出了上模加工工艺规程,包括所选择的毛坯材料、所用的加工机床,加工刀具及切削用量;最后,论文叙述了利用Pro/Engineer软件进行模拟数控加工、生成数控加工代码。本次设计是利用Pro/Engineer软件作为开发和制造的平台,根据制定的造型及模具设计方案,完成壳体零件(40336706
