摘要 本次设计的是塑料碗， 主要介绍了碗的设计思路、加工过程和碗的注射模的设计。这种聚丙烯水杯无毒、无味，密度小,强度、刚度、硬度、耐热性都较好,是人们日常生活中的必不可少的生活用品。 本次设计采纳的是注射成型。在设计过程中，首先对进行原材料分析，比较不同塑料的物理和化学性质从而选定碗的最佳原料为聚丙烯.然后计算碗的体积,初步选定注射机和标准模架，再进一步设计模具各个结构，最后对注射机进行校核. 关键词：注塑成型 注射机 模具Abstract This design is about bow。 It mainly introduces the design ideas 0f bow ， the processes ， and the injection mold 。 bow have many advantages， such as it's non-poisonous， unpalatable， low density， what’s more, it's strength ， stiffness, rigidity and heat-resistance are also good。 It's essential to daily life。 The design adopt the injection molding 。 During the design process， first， we analyse raw materials， and select PP as the best material of bowl by comparing the different physical and chemical properties of plastics. Then calculating the volume of a bowl. Following initially selected injection machine and the standard mold, design further structural of each mold. Finally， check on the injection machine。Key words : injection molding injection machine the mould 目录摘要...................................................................................................................................................IAbstract ............................................................................................................................................. 0 第一章 制品成型工艺分析 ............................................................................................................. 0 1 。 1 材料的选用 ..................................................................................................................... 0 1 。 2 注塑模工艺条件 ................................
