技术领域
本发明涉及用于注射模制机的模具的液压阀式浇口致动器。更具体地,本发明涉及延长液压阀式浇口致动器的寿命。
背景技术
现在,注射模制机在制造业中是常见的。在这些机器中,熔融塑料经由阀式浇口被迫压到用于制造固化的聚合物制件的模具中。
通常,注射模制机包括注射螺杆,注射螺杆将已加热的聚合物材料经由热流道组件迫压到用于制作最终模制件的模具中。该热流道组件包括一个或更多个副管道以及可动销,所述一个或更多个副管道附接至模具中的浇口,该可动销用于在注射循环期间打开及关闭阀式浇口。该销通过某种致动器提升或降低,其中液压活塞式致动器是最常用的。
这些致动器设计成将销抬离浇口座以开始注射,并且之后,当特定位置处的塑料的注射完成时,使销向降回至浇口中。在目前使用的大多数模具中,一个模具中使用多个浇口以通过致动器和浇口的共同排序来产生最佳的结果。
由于使用多个浇口,因此即使是致动器中的一个出现故障或磨损也会毁坏整个制件的模制成型。这在部件的寿命达到其寿命极限的情况下并且在这些制件的高容量运行期间尤其是个问题。如果由于有故障的阀式浇口致动器而使制件模制程序必须停止,则必须拆卸整个热流道组件以进行替换,从而导致昂贵且费时的停工和修理时间。更不用说在注意到并改正该问题之前可能已存在有缺陷的制件。
例如,已经发现的是,当配备有标准配置的密封件时,在30000至50000次的射出之后,由于内部密封件的失效,常规的序贯阀式浇口致动器易于泄露且反应迟缓。一些故障可能变得严重到足以因为冲刷而毁坏缸体壳。
销移动迟缓所引起的制件缺陷很难确定其根本原因。然而,可以确信,在许多情况下是由于致动器反应时间短致使SVG(序贯阀式浇口)的销移动缓慢,从而导致了这些缺陷以及制件的失效。
因此,在现有技术中存在着对提供如下更持久的液压阀式浇口致动器的需求,该液压阀式浇口致动器将能够承受诸如汽车工业中的大批量生产运行。
发明内容
依照本发明,提供用于在注射模制中使用的模具的具有增长的寿命的液压阀式浇口致动器。该致动器包括插入到具有可移动的阀式浇口销的热流道组件中的壳体。壳体中的孔接纳与浇口销连接的驱动活塞。在组件中的液压室使活塞升高及降低以驱动阀式浇口中的销。驱动活塞包括居中定位的周向双唇密封件。孔的壁包括用于与活塞的外周接合的一对周向密封件。所述密封件轴向地定位在活塞的所述居中定位的双唇密封件的两侧以密封及引导活塞。孔的周向密封件包括聚四氟乙烯环和由氟橡胶材料制成的第二密封部件,该聚四氟乙烯环在密封件失效下对孔进行保护。组合在一起的密封件使致动器的寿命增长至超过类似驱动阀的寿命的三倍。

具体实施方式
以下关于优选实施方式的描述本质上仅是示例性的,并且无意于限制本发明及其应用或用途。
根据本发明提供了一种液压阀式浇口致动器(在图1中大体上以10示出),当该液压阀式浇口致动器在注射模制机中的模具中的序贯阀式浇口中应用于高容量生产环境中时——诸如应用于汽车注射模制生产线——提供增长的寿命。
一般而言,阀包括一套替代的密封件(在图4中大体上在12处示出)。致动器10包括用于插入到具有可移动的阀式浇口销18的热流道组件工具背板16中的壳体14。壳体中的孔20接纳驱动活塞22,该驱动活塞22与浇口销18相连接以使销在孔20中上下移动。
在组件中的液压室24使活塞22升高和降低以驱使销18打开及关闭注射模具中的阀式浇口。
驱动活塞22包括在优选的实施方式中优选的居中定位的周向双唇密封件26,双唇密封件26是邵氏A硬度大致为大约90.25至大约99.75、优选为大约95的Hytrel材料(聚酯树脂族)。背衬密封件28在周向槽30中位于密封件26下层,周向槽30由活塞22中的两个径向延伸的壁32和34形成。背衬密封件28确保密封件26牢固地保持在槽30中,并且背衬密封件28具有大致为大约66.5至大约73.5、优选为大约70的邵氏A硬度。孔20的壁包括用于与活塞22的外周接合的一对周向密封件36和38。密封件36和38在壳体中轴向地定位于活塞22的居中定位的双唇密封件26的两侧以密封及引导活塞22。孔的周向密封件36和38是同样类型的两部分式密封件。如图4及图11中最佳地示出的,密封件36和38均包括内部的聚四氟乙烯环42和由氟橡胶材料制成的唇式的第二密封部件40,聚四氟乙烯环42在密封件失效的情况下对孔提供保护。本发明的密封部件40具有大致为大约76至大约84、优选为大约85的邵氏A硬度。聚四氟乙烯环42具有大致为大约52.25至大约57.25、优选为大约55的邵氏D硬度。在替代性实施例中,包含以下步骤:环40形成轴向唇部,并且聚四氟乙烯密封件嵌套在紧邻唇部形成的空间中。
密封件44由具有邵氏A硬度大致为大约66.5至大约73.5、优选为大约70的腈类材料制成,密封件44用于下方可移动密封板46的密封。密封板46借助于螺纹紧固件48保持在致动壳体处14。
在操作中,密封件26与现有技术中使用的基本“O”形环相比具有更好的擦拭密封效果,此外,密封件26及背衬密封件28占据了槽30内的所有空间,从而防止密封件26在槽内滚动。这增加了这种密封装置的寿命,因为可以确信的是,在现有技术中,“O”形环在槽内的滚动将导致“O”形环密封件发生破损从而引发致动器的故障。此外,内部聚四氟乙烯环密封件42的应用是坚固的并且足以防止在其他密封件失效的情况下金属与金属的接触及劣化,这也增长了致动器的寿命。安装在如本发明中所教示的成套部件上的组合在一起的密封件使致动器的寿命增长至超过如图中所示的使用常规密封件的类似驱动阀的寿命的三倍。
本发明的描述本质上仅是示例性的,并且因此,未偏离本发明主旨的变体均包含在本发明的范围内。这样的变体不能被视作偏离本发明的精神及范围。
