摘要
针对传统冷流道模具需要人工去除浇注系统凝料和冷切浇口技术效果不佳的现状,以某智能手机保护套为例,设计了具有热切浇口功能的手机保护套模具。首先根据产品搭接侧浇口的结构特点,设计了能够将浇口切除干净,且运动准确的切刀装置,并利用有限元分析方法确立了合适的进刀时间和驱动油缸。然后设计了合理的顶出和冷却机构,保证产品和浇注系统凝料在分离冷却后分别被安全顶出。
Aiming at the current situation that the traditional cold runner mold requires the manual removal of freezing materials in the gating system and the poor technical effect of cold-cutting gate,a mobile phone case was taken as an example to design a injection mold for the mobile phone case with a hot-cutting gate function.According to the structural characteristics of the lapping and side gate,an accurate motion cutting device was designed to ensure the clean gate cutting,and then a drive cylinder with appropriate infeed time was established by the finite element analysis method.Moreover,a reasonable ejector and cooling mechanism were designed to ensure the product and gating system ejected safely after separation and cooling.
