摘要： A sprue gated injected molding system having nozzles with a removable hollow gate insert received in a seat in the forward end of each nozzle to form the gate. Each gage insert has a forward portion with a tapered outer surface which abuts against a matching tapered surface of an opening through to mold to the cavity. The forward portion of the gate insert is resilient which ensures extremely good contact between them under bearing pressure due to thermal expansion of the nozzle. Thus optimum uniform heat transfer is provided between the gate insert and the cooled mold. The gate insert has a circumferential removal flange to facilitate it being pryed out of the seat if replacement is required. In an alternate embodiment an elongated torpedo is seated centrally in the melt bore of each nozzle. The torpedo has an outer retaining ring and a number of radially extending tapered fins which form melt flow channels between them. The torpedo is mounted with the retaining ring secured in the seat in the forward end of the nozzle by the gate insert and a pointed tip formed by the fins extending to provide additional heat in or adjacent the gate. The torpedo has pointed tips at opposite ends and is reversible for different dimensioned applications.
摘要翻译：浇口浇口注射成型系统具有喷嘴，其具有容纳在每个喷嘴的前端中的座中的可移除的中空浇口刀片，以形成浇口。每个量具插入件具有前部，其具有锥形的外表面，其与开口的匹配的锥形表面抵接以模制到空腔。门插入件的前部是弹性的，这确保了由于喷嘴的热膨胀而在轴承压力下它们之间的极好的接触。因此，在浇口插入件和冷却的模具之间提供最佳的均匀传热。门插入件具有周向移除法兰，以便在需要更换时便于将其从座椅中撬出。在替代实施例中，细长的鱼雷位于每个喷嘴的熔体孔中央。鱼雷具有外保持环和多个径向延伸的锥形翅片，它们之间形成熔体流动通道。鱼雷安装有固定环，其通过门插入件固定在喷嘴前端中的座中，并且由翅片形成的尖端延伸以在门中或邻近门处提供额外的热量。鱼雷在相对的两端有尖头，对于不同尺寸的应用是可逆的。

摘要： A number of heated injection molding nozzles are mounted along the side surface of a melt conveying manifold. In one embodiment of the invention, a connector collar having a tapered flange portion is bolted to the side surface of the manifold to provide each melt bore outlet. Each nozzle has a matching flange portion with a melt bore inlet extending laterally from a side surface. The nozzle is mounted on the manifold by securing the flange portions together by bolting a wedge clamp having two halves over the aligned flange portions. This accurately aligns the inlet with the outlet and allows the nozzle to be rotated to a particular angular position. In another embodiment, a melt conduit member is mounted between the manifold and each nozzle. The melt conduit member is clamped to the manifold after being rotated to a desired angular position about a first axis. A nozzle is clamped to the melt conduit member after being rotated to a desired angular position about a second axis which is substantially perpendicular to the first axis. Thus, each nozzle can be located with any desired angular orientation without the melt flowing through an acute angle bend.
摘要翻译：多个加热的注射成型喷嘴沿着熔体输送歧管的侧表面安装。在本发明的一个实施例中，具有锥形凸缘部分的连接器套环螺栓连接到歧管的侧表面以提供每个熔体孔出口。每个喷嘴具有匹配的凸缘部分，其中熔体孔入口从侧表面横向延伸。通过将具有两个半部的楔形夹具螺栓固定在对准的凸缘部分上方，将喷嘴固定在歧管上。这使得入口与出口精确对准，并允许喷嘴旋转到特定的角位置。在另一个实施例中，熔体管道构件安装在歧管和每个喷嘴之间。在围绕第一轴旋转到期望的角度位置之后，熔体管道构件被夹紧到歧管。在基本上垂直于第一轴线的第二轴线旋转到期望角度位置之后，将喷嘴夹紧到熔体管道构件。因此，每个喷嘴可以以任何期望的角度方向定位，而不会使熔体流过锐角弯曲部。

摘要： An injection molding system having at least one insulation gate seal extending outwardly to bridge an insulative air space between a heated nozzle and the adjacent cooled cavity plate. Each seal has a central bore therethrough to convey pressurized melt from the nozzle to the aligned gate. The outer end of each seal has a circular groove extending between a central portion and a surrounding flange portion. The flange portion is substantially larger in diameter than the gate and extends outwardly past the face of the central portion into sealing contact around the gate against the surrounding surface of the cavity plate. The combination of the clearance provided between the face of the central portion and the surrounding surface of the cavity plate and the distance between the gate and the surrounding flange portion limits the temperature of the cavity plate immediately around the gate, while still providing the necessary seal.

摘要： This invention relates to an injection molding system having a number of nozzles conveying melt from an elongated manifold to a common cavity. In the preferred embodiment, each heated nozzle has a melt channel which is offset from a central valve pin bore for conveying the melt to the gate. The melt channel extends through a side portion of the nozzle which is bolted to the side surface of the manifold. The bolts provide a seal against leakage of the pressurized melt, while at the same time allow slight lateral movement between the manifold and the nozzle. This provides for thermal expansion of the manifold relative to the nozzle which is accurately located in a well in the core. The system is used for large cavities which require large flow volumes and avoids the difficulty of accurate machining of the large molds to provide sealing.

摘要： This invention relates to a method of providing an injection molding heated nozzle with an improved electrical terminal. A plug is seated in a radial opening in the collar portion with heating element extending through it and the rear end of the heating element projecting a minimum distance from the front surface of the plug. The insulation and casing are stripped from the projecting portion and the exposed resistance wire is welded to a flat surface on a larger diameter threaded conductive stud. A sleeve having a threaded and broached inner surface is mounted over the stud with the outer end of the stud projecting beyond the outer end of the sleeve. The plug and sleeve are integrally brazed in place during the brazing step forming the rest of the nozzle. A liquid ceramic insulating material is poured to fill the space between the stud and the surrounding sleeve. A ceramic insulating washer and a steel washer are mounted on the projecting outer end of the threaded stud, before receiving the electrical lead which is held in place by a nut. The ceramic material bonds to the threads and grooves on the inner surface of the sleeve and to the stud and secures it against the applicaiton of lateral and axial forces, as well as torque and considerably reduces failure of the resistance wire.

摘要： This invention relates to an improved injection molding filter assembly to be located between the molding machine and the mold. The assembly has an elongated inner torpedo member with a generally cylindrical outer surface which is centrally located in a passage through a hollow outer member. The passage is defined by a generally cylindrical inner wall which is interrupted by an even number of inwardly opening longitudinally extending channels. Inlet channels extending from the inlet of the assembly and dead ending adjacent the outlet alternate with outlet channels extending from the outlet of the assembly and dead ending adjacent the inlet. Filtering apertures are formed between the outer surface of the torpedo member and the lands between the inlet and outlet channels through which the melt flows from the inlet channels to the outlet channels. A single elongated aperture may be formed at each land or a plurality of smaller apertures may be formed by providing alternating laterally extending ridges and grooves on the inner surfaces of the lands and/or on the outer surface of the torpedo member. Contaminants which are too large to pass through the filtering apertures accumulate adjacent the dead ends of the inlet channels. The outer member has a collar portion which may be detached to take out the torpedo member for periodic removal of accumulated contaminants. The location of the channels in the outer member provides improved heat flow characteristics and allows the width of the filtering slits to be quickly and easily changed by substituting a relatively inexpensive torpedo member having a different diameter.
