内容简介：

摘要 一个国家工业水平的高低，在很大程度上取决于模具工业发展的水平。模具工业的发展水平，是一个国家工业水平的重要标志之一。注塑模具是指用于成型塑料制件的模具。设计塑料模时，确定了模具结构之後即可对模具的各部分进行详细设计，即确定各模板和零件的尺寸，型腔和型芯尺寸等。这时将涉及有关材料收缩率等主要的设计参数。因而只有具体地掌握成形塑料的收缩率才能确定型腔各部分的尺寸。即使所选模具结构正确，但所用参数不当，就不可能生产出品质合格的塑件。本文介绍了童心吸水水杯杯盖的注塑模设计。首先对塑件制品进行工艺分析与研究。其次，进行分型面的选择，浇口的设计，决定模具采用三板式结构，水路冷却，结构简单，耐用，便于加工部件，生产效率高。利用推板对制品进行强制脱模。对模具的各个零件进行了设计与计算以及强度的校核。最后对模具材料的选择、使用与保养作了几点说明。关键词：童心吸水水杯杯盖 注塑模 三板式 强制脱模 AbstractA nations industrial level is largely decided by the developmental level of molding tool industry. Therefore, the level of molding tool industry is one of the important signs of its industrial level. Injecting plastic mold is a kind of molding tool that is used in modeled plastic pieces. This article deals with the injecting plastic mold design of Tongxin absorbing watercups cover. Firstly, carry out craft analysis and research on plastic products. Secondly, choose the dividing facet, design the sprinkling mouth, decide to employ the three-plank style and waterway cooling off. These structures are simple enough but enduring and easy to process the parts with high efficiency. Besides, use pushing plank to take off the mold compulsorily, design and calculate different parts of the molding tool and check its strength. Finally, make some illustration on the choice, use and maintain of the material of the molding tool. Key Words: Tongxin absorbing watercups cover i
