1、 1 摘摘 要要 本文以实际应用中的接触片为基础，详细介绍了接触片冲压模具的设 计方法，冲压模具由于其高效率、高品质的制造功能，在实际生产中极大 的节省了原材料和劳动力，所以正在得到越来越广泛的关注和应用。 针对实际的拨动杆设计出了一整套模具，对其工艺进行了分析,并对其 中的各个零件进行了具体的设计。由于此次零件的特殊性，本次设计着重 考虑了顶出装置的设计，选择了三板式结构和二次顶出方式，同时也分别 的介绍了注塑机的选择方法，塑件、模具型腔材料选择过程，型腔数量、 分型面、主流道、分流道、浇口、排气方式的选择方法，也对一些关键零 件进行了强度校核，最后介绍了模具的动作过程。 本文另加入了三维立

2、体设计，在传统二维 CAD 设计的基础上，配合当 今应用广泛的三维立体设计软件 Pro/Engineer 的设计效果图，使各个部分 表达的更加清晰，同时也对软件 Pro/Engineer 做了简单的介绍。 关键词：关键词：拨动杆；模具设计；冲压模；顶出机构；Pro/Engineer 2 Abstract The design method of injection mold for the Poke rod is introduced in detail based on the practical the Poke rod. The injection mold attracts more

3、attention and implement, due to its high efficiency, high manufacturing quality and saving raw material and the labor force in the actual production. A suit of injection mold is designed based on the the Poke rod. The processing is analyzed and every part is designed. As a result of this components

4、traits, the ejector structure is thought of emphatically and a 3-plank structure and secondary ejector style is chosen. Simultaneously, also introduces respectively injection molding machine choosing, models, the material of mold cavity choice process, the number of mold cavity, parting surface, main channel, sub-channel, gate, exhaust style, etc. In addition, the intensity of some key elements is checked. Finally, the motion process of mould is presented. 3D solid design is applied in the pap
