摘要
分析了电话机外壳上盖的塑件工艺特点 ,介绍了电话机外壳上盖注射成型模结构及模具的工作过程。重点介绍了电话机外壳上盖注射模结构的设计方法。分析和阐述了模芯零件的选材、热处理工艺 ,电话机外壳上盖的塑件的结构要素 ,塑件的尺寸公差和精度的选择 ,塑件的体积和质量的计算方法。此电话机外壳注射模设计的结构特点是点浇口形式的三分型面的注射模 ,是侧向抽芯注射模。经过生产验证 ,该模具结构设计巧妙 ,操作方便 ,使用寿命长 。
The technological characteristics of the above shell of telephone were analyzed. The die structure and working process of injection forming were introduced. The design methods of injection structure of above shell of telephone were mainly introduced. The selection of material for mould core,the heat treatment of mould,the main parts of structure of the spare parts of the plastics of the above shell of telephone,the selection of size tolerance and accurate degree of the spare parts of the plastics,the calculate method of volume and quality of the spare parts of the plastics were analyzed and stated. The structure peculiarity of the project is thrice minutes to touch the runner shape the standard injecting,and the cross range is whipped the rush pith and is injected the standard. Production proved that the mould structure was designed cleverly,the mould can be operated easily,the service life of mould is long and plastic parts products meet technical requirement.
