基于PRO/E的调料盒注塑模设计 摘要 本次模具所设计的课题是基于PRO/E调料盒注塑模设计，针对调料盒进行了相关的工艺、模具的相关设计。首先对塑料件材料ABS，塑料件的尺寸精度，使用性能，塑料表面质量，其结构布局进行分析，计划选用注射机，本模具利用CAD与PRO/E等软件对模具开始相应计算和相关分析。重点在于注塑模设计，起首分析可注塑性，对塑件外面质量不可轻视，表外面不可以出现较明显的接痕，和气泡疤痕，可以利用软件对注塑件可能出现的接触面痕和气泡进行分析。然后是可制造性，确认选定型腔数目，模具类型，模具主要布局结构，在模具主要结构设计中包括型腔结构，浇口的选择，型面计划，浇注体的设计，排气系统的设计，导向机构的设计，限位拉杆的设计，随后可以确选模具的首要布局。然后选择模架，校准开模行程，算出推出间隔大小，选定推出方式，设划侧抽芯机构，冷却系统，随之可以选定模具的总体布局结构。分析模具结构和功能，其中包括型腔的结构，型芯的结构，型芯镶件的结构，模具导向复位的结构。计算成型零件工作尺寸，包括型芯尺寸大小，型腔尺寸大校最后是模具的安装与试模，使用PRO/E绘制模具安装结构图。 关键词：注塑模；调料盒； PRO/E Abstract The subject of this die desig
