1、毕业设计(论文) I 旋钮注塑模模具设计 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。 从零件图分析,该零件的材料为 ABS 塑料且需大批量生产,所以选用注塑模 具。在本次注塑模具设计(旋钮)过程中,介绍了注射成
2、型的基本原理,对注塑产 品提出了设计原则,主要介绍了浇注系统和推出系统的设计过程。 通过对注塑模具设计(旋钮)及型腔数控加工工艺编程的设计,我对注塑模 具有了一定的认识,对其设计原理及设计步骤也有了更深的认识,并掌握了塑射 成型模具的结构特点及设计计算方法,对能独立设计模具有个一次不错的锻炼机 会。 关键词:ABS 塑料;塑料模具;注射成型;模具设计; 毕业设计(论文) II Caps injection mold die design ABSTRACT In recent years, Chinas household electrical appliance industry in the
3、 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 a
4、n 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. Analysis from the parts, materials for the components are Acrylonitrile Butadiene Styrene and the need to mass production
