中北大学2013届本科毕业设计说明书 PAGE \* MERGEFORMAT1 汽车保险杠注射模具设计 摘要：随着汽车工业的发展，汽车保险杆作为一种重要的安全装置走向了革新的道路，保险杆除了有保护功能外，还要追求与车体造型的和谐与统一，追求本身的轻量化和表亮化。本文叙述了其注塑模具设计的一般流程，包括塑胶件的工艺分析；模具具体结构的设计；及模具各种2D、3D工程图的绘制；热流道技术；注塑成型设备的选择；相关参数的计算与说明等等。相比其他注塑模设计，本文采用目前模具设计中先进的热流道技术，包括喷嘴的设计、流道板的具体参数的选择与设计等等。本塑件是一个宽度1.6米左右，高0.3米左右，厚度2.5~4厘米之间的汽车后保险杠。塑件整体尺寸较大，无螺纹，所以不需要涉及螺纹设计。这次设计的模具的顶出方式采用简单脱模机构中的顶杆脱模机构。顶杆脱模机构是最典型的简单脱模机构，它结构简单，制造容易且维修方便。在整个设计工作中，本文主要运用3D软件Pro/E以及CAD软件来完成产品的造型。此外还利用CAD绘制了模具装配图以及各种成型零件图。这是第一次利用绘图软件对整套模具进行设计，对所学知识进行了全面巩固，意义重大！ 关键词：热流道；注塑模设计；Pro/E; CAD Bumper Mould Design Abstract：The birth of mobile phones has changed many peoples living habits, and the cell phone charge at GM because of its exceptional circumstances (price, convenience, etc.) get more people liked it, so in our lives was widely used. Block, which is connected rechargeable cell phone battery charging devices and the key positions. This paper describes the design of its injection mold of the general processes, including plastic pieces of technology analysis; specific structure of the mold and die various 2 D, 3D rendering of the plan; hot runner technology; injection molding equipment choice of the relevant parameters Calculation and description, and so on. The plastic parts are a width of 1.6 meters, 0.3 meters high, the thickness of 2.5 to 4 cm between the car rear bumper. Overall size larger plastic parts, non-threaded, so do not involve thread design. The design of the mold ejection ejection mechanism with a simple way of mandrel pulling mechanism. Mandrel ejection mechanism is the most typical simple stripping mechanism, its simple structure, easy to manufacture and easy maintenance.Compared to other injection mold design, mold design currently used in this paper in the hot runner advanced technologies, including the nozzle design, flow-specific parameters of choice and design, and so on. Throughout the design work in this paper use 3 D software Pro / E to complete the modeling products. In addition, also has drawn u
