塑料洗脸盆的注塑模设计
摘要
本文主要介绍了注射模具的特点和发展趋势,叙述了塑料盆注射模具设计和相关的计算过程,介绍了该塑件的成型工艺、注射模具的结构特点与工作过程,以及在注射模设计中应注意的问题。在对塑料洗脸盆的模具设计过程中,本次设计的主要内容如下:设计的塑件比较的合理;选择的分型面有利于塑件成型;设计的脱模机构不但结构简单,而且脱模动作稳定可靠;选择的进浇口不影响塑件外观,而且可以保证塑件充填均匀;冷却水道的设计可以使模具效率达到最高,保证了塑件质量要求;在设计的过程中用了计算机辅助设计软件如CAD等使设计更合理、更有效;本次设计大量使用标准件,使模具制作成本大大降低;最关键的一点就是本次设计已达到实际生产的要求。
关键词:塑料洗脸盆,注射模,分型面,侧抽芯,脱模机构。
