一种应用于主喷嘴与分流板之间的防漏胶结构
本技术涉及注塑模具
,特别涉及到一种应用于主喷嘴与分流板之间的防漏胶结构。
技术介绍
注塑模具是一种生产塑胶制品的工具,也是赋予塑胶制品完整结构和精确尺寸的工具。注塑成型是批量生产某些形状复杂部件时用到的一种加工方法。具体指将受热融化的塑料由注塑机高压射入模腔,经冷却固化后,得到成形品。现有技术的主喷嘴与分流板之间的连接方式绝大部分为螺纹连接,在主喷嘴的下端的外周面上设有外螺纹,在分流板上设有主喷嘴安装腔,在主喷嘴安装腔的内周面上设有与外螺纹相配合的内螺纹,采用此种结构主喷嘴与分流板在拆卸过程中极易损坏主喷嘴与分流板连接处的螺牙,不但降低了主喷嘴与分流板之间稳定性能,并且还极易使熔融的塑胶从主喷嘴与分流板的连接处漏出,提高了漏胶的风险,给注塑模具的注塑工作带来了较大的不便。然而针对现有技术的不足,研发者有必要研制一种设计合理、结构简单、拆装方便,能够将主喷嘴牢牢的安装在分流板上,提高了主喷嘴与分流板之间的稳定性能,避免熔融的塑胶从主喷嘴与分流板的连接处漏出,降低了漏胶的风险的应用于主喷嘴与分流板之间的防漏胶结构。
