1、河南科技大学毕业设计（论文）I打印机墨盒卡头注射工艺及模具设计摘 要塑料制品具有原料来源丰富、价格低廉、性能优良等特点。它在电脑、手机、汽车、电机、电器、仪器仪表、家电和通讯产品制造中具有不可替代的作用，应用极其广泛。注射成形是成形热塑件的主要方法，因此应用范围很广。墨盒卡头结构较为复杂、质量较小、壁厚薄，是一个小型塑料注射件；其形状中间为盒形，一端带有两个勾形，另一端有侧孔。通过墨盒卡头的这些特点以及零件原材料的特性分析和比较，设计点浇口双分型面带侧向抽芯的注射模具。通过模具侧抽芯结构以及零件要求，确定一模双腔的型腔对称排布结构。根据墨盒卡头原材料的工艺性能确定模具的浇注系统。然后，根据注射
2、体积选择注射机并校核。侧向抽芯机构采用常用斜导柱侧抽芯机构。根据零件结构形状，设计两侧对称的抽芯机构。设计四个斜导柱，每侧两个对称分布。推出系统采用推杆推出系统及复位杆复位。而浇道凝料采用挡板拉断点浇口，定距拉杆和弹簧配合的推出系统。导向机构采用导柱导向结构，采用带头导柱和直导套配合导向机构。导柱和导套都按标准件进行设计。冷却系统采用冷却水冷却，水道根据模具结构设计了正向和侧向两个方向的流向。此模具设计紧凑，采用一模双腔结构，满足了生产墨盒卡头的技术要求，并保证了较高的生产效率。关键词：注塑模，塑料模，侧向抽芯，双分型面，墨盒卡头INJECTION PROCESSES AND MOLD DES
