Abstract

本实用新型涉及一种具有龙门架的注塑模具顶出油缸的安装机构,该机构的顶出油缸上安装有为其提供液压油的进出油管,动模的侧部设置有油缸龙门架,油缸龙门架呈∏字型,油缸龙门架的两底脚固定在顶针板上,顶出油缸位于油缸龙门架内,顶出油缸的缸体固定在动模板座上,顶出油缸的油缸杆端部通过连接件固定在油缸龙门架顶部。本实用新型在顶出、复位过程中,顶出油缸的缸体以及其上的进出油管是静止不动的,有效的起到保护进出油管的作用。同时,整个顶出油缸位于油缸龙门架内,因此较好的受到油缸龙门架的保护,避免了油缸杆被撞弯导致不能顶出或油缸漏油。

Description

具有龙门架的注塑模具顶出油缸的安装机构
技术领域
本实用新型涉及一种具有龙门架的注塑模具顶出油缸的安装机构,属于模具技术领域。
背景技术
顶出机构是注塑模具必不可少的机构,其主要作用是对成型后的塑料产品进行顶出脱模。如图1所示,目前的顶出机构主要包括顶出油缸12、动模座板15和顶针板13,所述顶出油缸12上安装有进出油管11,所述顶出油缸12的缸体固定在所述顶针板13上,所述顶出油缸12的活塞杆14端部固定在所述动模座板15上。这种顶出机构存在如下缺点:由于顶出油缸12的活塞杆14是固定在动模座板15上,顶出油缸12的缸体固定在顶针板13上,当顶出油缸12顶出时,顶出油缸12与顶针板13一起向上运动,每顶出复位一次,进出油管11都要弯曲变形一次,时间长后,进出油管易破裂或漏油。为此,本发明人设计出一种注塑模具顶出油缸的安装机构,该机构将顶出油缸的缸体固定在动模上,顶出油缸的油缸杆端部固定在顶针板上。工作时,油缸杆与顶针板一起上下运动,顶出油缸的缸体以及安装在缸体上的进出油管不动,这样有效的起到保护了进出油管的作用,但仍存在如下问题:模具在存放时,顶针板是处于复位状态,油缸杆是露在外面的,容易被撞弯,会导致不能顶出或油缸漏油。
实用新型内容  
针对背景技术中的缺陷,本实用新型提供一种保护整个顶出油缸的具有龙门架的注塑模具顶出油缸的安装机构。
为达到上述实用新型目的本实用新型所采用的技术方案是:
具有龙门架的注塑模具顶出油缸的安装机构,包括顶出油缸、动模板座、顶针板和动模,所述顶出油缸上安装有为其提供液压油的进出油管,其特征在于所述动模的侧部设置有油缸龙门架,所述油缸龙门架呈∏字型,所述油缸龙门架的两底脚固定在所述顶针板上,所述顶出油缸位于所述油缸龙门架内,所述顶出油缸的缸体固定在所述动模板座上,所述顶出油缸的油缸杆端部通过连接件固定在所述油缸龙门架顶部。
本实用新型将顶出油缸的缸体固定在动模板座上,而顶出油缸的油缸杆通过带动油缸龙门架进而带动顶针板运动,在顶出、复位过程中,顶出油缸的缸体以及其上的进出油管是静止不动的,有效的起到保护进出油管的作用。同时,整个顶出油缸位于油缸龙门架内,因此较好的受到油缸龙门架的保护,避免了油缸杆被撞弯导致不能顶出或油缸漏油。
下面结合附图对本实用新型的实施方式做进一步说明。
附图说明
图1是一种现有技术的结构示意图。
图2是本实用新型一种较佳实施方式的结构示意图。
具体实施方式
如图2所示,具有龙门架的注塑模具顶出油缸的安装机构,包括顶出油缸3、动模板座5、顶针板6和动模7,所述顶出油缸3上安装有为其提供液压油的进出油管4,其特征在于所述动模7的侧部设置有油缸龙门架1,所述油缸龙门架1呈∏字型,所述油缸龙门架1的两底脚固定在所述顶针板6上,所述顶出油缸3位于所述油缸龙门架1内,所述顶出油缸3的缸体固定在所述动模板座5上,所述顶出油缸3的油缸杆2端部通过连接件固定在所述油缸龙门架1顶部。
本实用新型将顶出油缸的缸体固定在动模板座上,而顶出油缸的油缸杆通过带动油缸龙门架进而带动顶针板运动,在顶出、复位过程中,顶出油缸的缸体以及其上的进出油管是静止不动的,不用弯曲变形,有利于进出油管的耐久使用,有效的起到保护进出油管的作用。同时,整个顶出油缸位于油缸龙门架内,因此较好的受到油缸龙门架的保护,避免了油缸杆被撞弯导致不能顶出或油缸漏油。
以上详细描述了本实用新型的较佳具体实施例。应当理解,本领域的普通技术无需创造性劳动就可以根据本实用新型的构思作出诸多修改和变化。因此,凡本技术领域中技术人员依本实用新型的构思在现有技术的基础上通过逻辑分析、推理或者有限的实验可以得到的技术方案,皆应落入本实用新型的保护范围内。
