塑料注塑模具设计---带轮 专业名称：机电一体化　作者： 指导教师：戴珊珊 中文摘要 摘要：近年来，我国家电工业的高速发展对模具工业，尤其是塑料模具提出了越来越高的要求，2007年，塑料模具在整个模具行业中所占比例已上升到20%左右，据有关专家预测，在未来几年中，中国塑料模具工业还将持续保持年均增长速度达到10%以上的较高速度的发展。国内塑料模具市场以注塑模具需求量最大，其中发展重点为工程塑料模具。 明确了设计思路，确定了注射成型工艺过程并对各个具体部分进行了详细的计算和校核。如此设计出的结构可确保模具工作运用可靠，保证了与其他部件的配合。最后用autoCAD绘制了一套模具装配图和零件图。 本课题通过对带轮的注射模具设计，巩固和深化了所学知识，取得了比较满意的效果，达到了预期的设计意图 关键词：塑料模具，注射成型 In recent years, Chinas household electrical appliance industry in the development of high-speed tooling industry, in particular the plastic mold of the ever-increasing demands. In 2007, the plastic mold industry in the entire Die share has risen to 20% According to the experts predict that in the next few years, China plastic mold industry will continue to maintain an average annual growth rate of 10% over the high rate of development. Domestic market to plastic mold injection mold greatest demand, which focused on the development of engineering plastics die. Plastic injection molding molding is an important method, which is primarily applicable to thermoplastic plastic molding, Molding can be a complex shape of precision plastic parts. Defined the design, determine the injection molding process as well as some specific details of the calculation and verification. The design of such a structure can be used to ensure reliable Die work to ensure that the other parts of the tie. Finally, a set of auto mapping mold parts and assembly plans. The subject of belt injection mold design, and to consolidate and deepen the learning, has been fairly satisfied with the results, achieved the desired design intent Keywords : plastic mold; injection molding; 前言目前世界模具市场供不应求，模具的主要出口国是美国，日本，法国，瑞士等国家。中国模具出口数量极少，但中国模具钳工技术水平高，劳动成本低，只要配备一些先进的数控制模设备，提高模具加工质量，缩短生产周期，沟通外贸渠道，模具出口将会有很大发展。研究和发展模具技术，提高模具技术水平，对于促进国民经济的发展有着特别重要的意义。目前，全世界模具的年产值约为650亿美元，我国模具工业的产值在国际上排名位居第三位，仅次于日本和美国。虽然近几年来，我国模具工业的技术水平已取得了很大的进步，但总体上与工业发达的国家相比仍有较大的差距。纵观发达国家对模具工业的认识与重视，我们感受到制造理念陈旧则是我国模具工业发展滞后的直接原因。模具技术水平的高低，决定着产品的质量、效益和新产品开发能力，它已成为衡
