模具专业论文范文 Abstract With the development of the plastic industry, the plastic injection mould has already been become one of main methods of manufacturing plastic products. By designing Ming Yi automobile combinative instrument cover, this paper firstly introduces the choosing basis and significance of the subject, its home and abroad studying station and main studying contents with its adopting methods, design’s difficulties and solutions, briefly expounding its development prospects. Next, the whole design process of injection mould is introduced, that is, analysis plastic part, choose injection machine with some of its parameters being checked so as to satisfy design demands, then the injection mould overall design is introduced, such as the forming parts and components design forming plastic part’s geometry and dimension, the pouring systems design transporting melt plastics, the overflow and bleed system design discharging air which affects plastic part’s precision, the temperature adjusted system design only designing the cooling system here, demould mechanism design isolating and retrieving already molding part, and mould-frame design. UG drawing software is utilized to accomplish the forming parts and components design, in addition helix-pillar and moving-core are used to form and extract the side-hole, helix-slider is used to extract the pock-hole’s block ears. Experiences are expounded in the end of the paper. Keywords：Injection mould ；Cooling system；Pouring system； Side-extracting core mechanism ；Helix-slider 摘 要 随着塑料工业的发展，塑料注塑模已经成为塑料制品接着介绍了注塑模的整个设计流程，分析塑件、选取注射机并作出部分参数的校核，然后是注塑模的整体设计，包括成型塑件几何形状和尺寸的成型部分及其零部件设计、输送熔融塑料的浇注系统设计、排出影响塑件精度气体的排溢与引气系统设计、这里只进行冷却系统设计的温度调节系统设计、分离并取出成型塑件的脱模机构设计以及模架设计。的主要成型方法之一。 针对路宝车组合仪表罩注塑模的设计，本文首先介绍了课题选择的依据和意义、课题的国内外研究现状、课题的主要内容及拟采取的方法、设计的难点与解决方法和注塑模的发展前景的简述。本文利用UG绘图软件完成成型部分及其零部件的设计，另外利用斜导柱和活动型芯完成塑件上侧向凹孔的抽芯动作，凹孔耳座的脱出由组合斜滑块完成。论文最后阐述了此次设计的心得体会。 关键词：注塑模 ；冷却系统；浇注系统；侧向抽芯机构；斜滑块 论文目录，请与本站客服联系查看。
