    Abstract: Multi-cavity injection molding apparatus includes a plurality of injection nozzles, each of which has a two-piece tip assembly in the nature of a replaceable tip and a retainer that detachably secures the tip to the nozzle body. The retainers are constructed from material having a lower coefficient of thermal conductivity than the tips so that the retainers also serve to insulate the tips from the relatively cold, surrounding heat sink presented by the mold. Although each retainer prevents its tip from being unintentionally axially released from the nozzle body, the retainer engages the tip at only two axially spaced locations along its length so as to present an insulating air gap in surrounding relationship to much of the tip. The otherwise exposed end of the air gap is sealed off when the nozzle is hot by virtue of a sealing collar on the retainer that progressively tightens against the cooperating, beveled surface of the tip as the tip heats up. Each nozzle is mounted on the manifold block in a ball and socket relationship so that the nozzles can swivel and self-align as the manifold block and nozzles heat up from room temperature to operating temperature at the commencement of the injection process.

    Abstract translation: 多空腔注射成型装置包括多个注射喷嘴,每个注射喷嘴具有可更换尖端的两件式末端组件和可拆卸地将尖端固定到喷嘴体的保持器。 保持器由具有比尖端更低的导热系数的材料构成,使得保持器还用于使尖端与由模具呈现的相对冷的周围的散热器绝缘。 虽然每个保持器防止其尖端被无意地从喷嘴主体轴向地释放,但是保持器仅沿着其长度仅在两个轴向间隔开的位置处接合尖端,以便呈现与大部分尖端相关的绝缘空气间隙。 当喷嘴热时,气隙的另外暴露的一端由于保持器上的密封环被密封,当尖端加热时,该密封环逐渐紧固在尖端的配合的斜面上。 每个喷嘴以球和插座的关系安装在歧管块上,使得喷嘴可以随着歧管块和喷嘴在注射过程开始时从室温升高到工作温度而旋转和自对准。

    Abstract: A mold gate insert (24f) includes a mold gate insert body, which is comprised of a material having a high thermal conductivity, and a thermal insulation element (74), which is nested in the mold gate insert body. The thermal insulation element (74) is provided to abut a nozzle seal (28f) and align the nozzle with a mold gate (34f). The amount of heat transferred from the nozzle to the mold gate insert (24f) is reduced by the thermal insulation element (74).

    Abstract: A mixer method and apparatus for use generally in injection molding machines is provided. The apparatus and method is generally comprised of a mixer insert that retains a mixing element that is sealingly inserted in the injection molding machine, for example a hot runner manifold. The mixing element reduces the melt imbalances in a flowing melt stream for the formation of improved molded parts.

    Abstract: A hot runner mould for injection moulding multilayered mouldings by simultaneously injecting various plastic melts into several cavities has a hot runner block (23a-c) slidingly supported between a top plate (21) at the side of the extruder and a hot runner plate (22) at the side of the cavities. A joining piece (24) firmly secured to said hot runner block is coupled to a feed bush (12) slidingly mounted on the top plate (21). The hot runner plate (22) can thus expand freely with temperature changes and the compression forces of the extruder do not act upon the hot runner block (23a-c) but are absorbed by the top plate (21). The feed paths for the various plastic melts change thanks to the structure in several parts of the hot runner block (23a-c) and to the controlled expansion movements of the hot runner block (23a-c) that are identical for all cavities.
