设计简介
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，2004年，塑料模具在整个模具行业中所占比例已上升到30%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。
注射成型是塑料成型的一种重要方法，它主要适用于热塑性塑料的成型，可以一次成型形状复杂的精密塑件。本课题就是将小家电的光驱滑轮座作为设计模型，将注射模具的相关知识作为依据，阐述塑料注射模具的设计过程。
本设计对光驱滑轮座进行的注塑模设计，利用UG软件对塑件进行了实体造型，对塑件结构进行了工艺分析。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。
本课题通过对光驱滑轮座的注射模具设计，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
In recent years, China's household electrical appliance industry in the development of high-speed tooling industry, in particular the plastic mold of the ever-increasing demands. In 2004, the plastic mold industry in the entire Die share has risen to 30% 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. Is the drive pulley block as a design model, the injection mold-related knowledge as a basis for elaborate plastic injection mold design process. The drive pulley block for the injection mold design, the use of software UG plastic parts for the solid modeling, Plastic Parts of the structure analysis for the process. 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 drive pulley block 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; Mold design
