    • To facilitate cleaning of melt channels in a runner system (102) in a centre-section carrier (20) or the like, a multi-piece interface adaptor (114, 116, 118) is detailed in FIG. 4. A male portion (114) of the interface adaptor (112) is securely coupled to the runner system (102) to extend the melt channel (63) thereof. The male portion (114) preferably includes a branching feature (124) that splits melt flow into opposing directions to feed distinct nozzles (60, 62). A female portion (116) of the interface adaptor includes bores (140, 142) that align with the branching feature (124, 134, 136) and support the mounting of nozzles (60, 62) therein. The female portion (116) is fixedly secured within the carrier (20). The male portion (114) and the female portion (116) are slidably engageable with one another along sealing surfaces (130, 220). At system operating temperatures, effective operational sealing occurs as a result of relative thermal expansion between the male portion (114) and the female portion (116). At lower temperatures, pulling of the runner system (102) along an axis aligned with its melt channel (63) permits the male portion (114) to be separated from the female portion (116) by disengaging the sealing surfaces (130, 220), thereby granting easy access to the melt channels and the branching feature (124) when the runner system (102) is removed from the carrier (20).
    • 为了便于在中心部分载体(20)等中的流道系统(102)中清洗熔体通道,在图1中详细描述了多件式接口适配器(114,116,118)。 接口适配器(112)的阳部分(114)牢固地联接到流道系统(102)以延伸其熔体通道(63)。 阳部分(114)优选地包括分支特征(124),其将熔体流分解成相反的方向以输送不同的喷嘴(60,62)。 接口适配器的阴部分(116)包括与分支特征(124,134,136)对齐并且支撑其中的喷嘴(60,62)的安装的孔(140,142)。 阴部分(116)固定地固定在载体(20)内。 阳部分(114)和阴部分(116)可沿着密封表面(130,220)彼此可滑动地接合。 在系统操作温度下,由于阳部分(114)和阴部分(116)之间的相对热膨胀,发生有效的操作密封。 在较低温度下,沿与其熔体通道(63)对准的轴线拉动流道系统(102)允许阳部分(114)通过使密封表面(130,220)脱离而与阴部分(116)分离, 从而当流道系统(102)从载体(20)移除时,允许容易地进入熔体通道和分支特征(124)。

    • According to embodiments of the present invention, there is provided a slide bar (108) for slidably linking a split mold insert (116, 118) to a first mold half of an injection mold for forming a preform (302) capable of being blow-molded into a container. The slide bar (108) comprises a base structure (109a) defining a first slide interface (109b) for linking the base structure to an actuating bar (110,118) of the injection mold; a second slide interface (109c) for receiving the split mold insert (116, 118); a third slide interface (109d) for cooperating with a locking structure of the first mold half (1106) of the injection mold; the second slide interface (109c) and the third slide interface (109d) formed on opposing extremes of the base structure (109a).
    • 根据本发明的实施例,提供了一种滑动杆(108),用于将分开的模具插入件(116,118)可滑动地连接到注射模具的第一半模,用于形成能够被吹塑的预成型件(302) 模制成容器。 滑杆(108)包括限定用于将基座结构与注射模具的致动杆(110,118)连接的第一滑动界面(109b)的基座结构(109a) 用于接收分割模具插入件(116,118)的第二滑动界面(109c); 第三滑动界面(109d),用于与注射模具的第一半模(1106)的锁定结构配合; 所述第二滑动界面(109c)和所述第三滑动界面(109d)形成在所述基部结构(109a)的相对的极限上。
