    • A nozzle assembly for use in injection molding comprises a pair of spacers acting between the manifold and either a cover plate or a hot runner plate of an injection molding machine to apply a contact pressure between the nozzle body melt channel and the manifold melt channel to achieve a seal therebetween. The resilience of the spacers result in an increased operational temperature range for the nozzle assembly, the contact pressure being generated and/or maintained over the range of the operational temperatures. An additional advantage is provided in that the nozzle assembly is compact and can be closely spaced with similar nozzle assemblies to achieve center spacings as small as eight millimeters. The assemblies can be mounted and/or removed from the cavity of the manifold plate, and/or changing of the nozzle heater elements, without requiring removal of the mold from the injection mold machine. In one embodiment, the nozzle assemblies can be removed or mounted by removing a cover plate from the manifold plate, the cover plate being capable of retaining multiple nozzle assemblies in place. In another embodiment, the nozzle assembly has a mounting flange and one or more bolts extend through the and engage the manifold plate and these bolts allow mounting and removal of the nozzle assembly.
    • 用于注射成型的喷嘴组件包括一对间隔件,其作用在歧管与注射成型机的盖板或热流道板之间,以在喷嘴体熔体通道和歧管熔体通道之间施加接触压力,以实现 之间的密封。 间隔物的弹性导致喷嘴组件的增加的工作温度范围,在工作温度的范围内产生和/或维持接触压力。 提供了一个额外的优点,因为喷嘴组件是紧凑的并且可以与类似的喷嘴组件紧密地间隔开来,以实现小到8毫米的中心间距。 组件可以从歧管板的空腔中安装和/或移除,和/或改变喷嘴加热器元件,而不需要将模具从注射模具机器中取出。 在一个实施例中,可以通过从歧管板上移除盖板来移除或安装喷嘴组件,盖板能够将多个喷嘴组件保持在适当位置。 在另一个实施例中,喷嘴组件具有安装凸缘,并且一个或多个螺栓延伸穿过并接合歧管板,并且这些螺栓允许喷嘴组件的安装和拆卸。

    • An apparatus and method for folding a hinged molded part in a molding machine. As a part-removal apparatus, preferably a swing arm mechanism, grips one of the lid portion or the base portion of the molded part and moves the molded part out of the mold, a deflector connected to a portion of the mold engages the other portion of the part and initiates folding of the lid portion to the base portion at the hinge. The deflector further folds the part as the mold closes. The portions of the part are pushed together and latched in one embodiment by the swing arm mechanism that grips and moves the molded part against the deflector, and in another embodiment by a closing actuator operated separately from the swing arm mechanism.
    • 一种用于在模制机中折叠铰接模制件的装置和方法。 作为部件去除装置,优选地是摆臂机构,夹住模制部件的盖部分或基部中的一个并将模制部件移出模具,连接到模具的一部分的偏转器与另一部分接合 并且在铰链处开始将盖部分折叠到基部。 当模具关闭时,导流板进一步折叠该部件。 在一个实施例中,部件的部分通过摆臂机构被推在一起并锁定,所述摆臂机构将模制部件夹紧并移动抵靠偏转器,并且在另一实施例中通过与摆臂机构分离地操作的关闭致动器。
