本科毕业设计(论文) 题目：电话机底座注塑模具设计 系 别：机电信息系 专 业：机械设计制造及其自动化 班 级： 学 生： 学 号： 指导教师： 2013年05月 电话机底座注塑模具设计 摘要 模具是工业生产的基础工艺装备，也是发展和实现少无切削技术不可缺少的工具。它在工业生产中使用极为广泛，是当代工业生产的重要手段和工艺发展方向，许多现代工业的发展和技术水平的提高，在很大程度上取决于模具工业的发展水平。因此，模具技术发展状况及水平的高低，直接影响到工业产品的发展。也是衡量一个国家工艺水平的重要标志之一。 本文主要论述了塑料注射模的基本原理和设计过程，并着重讲述了充电器外壳注射模的设计过程。首先，讲述了模具的作用和国内外的发展状况及其发展方向。然后论述了方案的选择和确定。再次对于所确定的方案给出了详细的设计过程和计算过程，最后还对所设计的模具进行了经济性可行性分析。此次设计中，最关键的是确定型芯和型腔的结构，此外还分析了模具受力，脱模机构的设计、冷却系统的设计等。 总的来说，所设计的这套模具经济合理，可行性强，生产方便，是一套实用性较强的模具。 关键词：注射模；定模；动模；抽芯；斜导柱 Telephone base injection mold design Abstract The molding tool is a foundation craft that industry produce to equip, it also a development with realizes the little having no slice the indispensable tool in the technique of cutting .It is in industry produce the usage is extremely extensive, it an important means that contemporary industry produce to develop the direction with the craft, many modern industrial developments with horizontal exaltation in technique, be decided by the industrial development in molding tool level to a large extent. Therefore, moldings tool technique development condition and horizontal and high and low, affect the development of the industry product directly. Too is to measure the one of the horizontal and important markings in a national craft. The graduation project title is the camera bracket a parts injection mold design., this text discussed primarily the plastics injects the basic principle of the mold with design the process, combining to emphasize to relate the Chargers shell inject the design process of the mold. First, related the function of the molding tool with domestic and international development condition and its development directions. Then discussed the choice of the project with certain. Returns a project for making sure give a detailed design process with compute process; very much again the molding tool to design t
