汽车保险杠模设计 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。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。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 AbstractThe 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 up the mold assembly drawing as well as each kind of Molding Parts drawing using CAD . This is that the first time makes use of the software drawing to carry out design on package mould
