摘要 进入二十一世纪以来，中国塑料工业取得了令世人瞩目的成就，实现了历史性的跨越。蓬勃发展的中国塑料工业，在中国现代化经济建设中发挥着越来越大的作用。塑料制品在人们的日常生活中随处可见，因此其注塑模具的需求也日益增多，市场前景广泛，而且因为不同塑件的外形不同，注塑模具也就有了很大的不同。 本设计是关于顶块的注塑模具设计，通过注塑机注塑成形零件。首先运用UG对塑件进行三维图的绘制，然后转成二维模型，进行导出，再运用AutoCAD软件修改二维模型。介绍了注塑机的选用，塑件的选材，浇注系统的设计，分型面及型腔数目的设计，导向、脱模及冷却系统的设计等，以及对模具的校核。 随着塑料加工工业持续快速发展，塑料制品在工业、农业、军事及人民生活的各个领域得到广泛的应用，塑料制品的研究、生成与应用开发得到迅速发展，塑料模具的设计、制造技术也随之不断提高。塑料制品业是一个新兴大行业。随着我国国民经济持续高速发展已逐步发展壮大，自上世纪90年代以来，塑料行业一直保持在10%以上的增长速度，已成为轻工业的支柱产业之一。随着CAD/CAM/CAE技术的引用，更是显著提高了模具设计的效率，减少模具设计过程中的失误，提高了模具和塑件的质量，缩短了生产周期，降低了模具和塑件的成本。 关键词: 模具设计 注塑模具 顶块 Pro/E AbstractInto the 21th century, Chinas plastics industry has made achievements that attracted worldwide attention, achieved a historic leap. Chinas booming plastics industry, economic modernization in China is playing an increasingly important role. Plastic products in peoples daily life everywhere, so the injection mold growing demand, broad market prospects, but also because of different shape with different plastic parts, injection molds will have a big difference. This design is about theTop block injection mold design, injection molding parts by injection molding machine. First use of UG on plasticPieces of three-dimensional mapping, and then turn into a two-dimensional model, export, re-use of AutoCAD software to modify the two-dimensional model. Describes the selection of injection molding machines, plastics material selection, design of gating system, the number of sub-surface and cavity design, direction, stripping and cooling system design, as well as checking on the mold. With the sustained and rapid development of plastic processing industry, plastic products in the industrial, agricultural, military and peoples life has been widely used in various fields, plastic products, research, generation and application development is the rapid development, plastic mold design and manufacturing technology with S continues to increase. Plastic products industry is an emerging industry. With the rapid development of Chinas national economy has gradually grown since the last century, 90 years, the plastics industry has remained at over 10% growth rate, has become one of pillar industries in light industry. With the CAD / CAM / CAE technology, reference, but also significantly improve the efficiency of mold design, mold design process to reduce errors and improve the quality of molds and plastic parts, sh
