摘要： A molding arrangement is provided for multi-level stack molds wherein mold sets and runners are made up of modular sections interchangeable individually or as larger assemblies for exchanging molds for one part for those for different parts or exchanging runners between hot tip and valve gate designs to accommodate different molding arrangements. The arrangement has discrete melt paths for each mold level, at least some of which extend around rather than through the mold levels and which incorporate readily separable connectors. This enables one set of molds and possibly as well the runners for one mold level to be interchanged without interfering with the mold and runner arrangement for an adjacent level.

摘要： A method for connecting and disconnecting an injection molding machine to and from a shutoff assembly includes the steps of mating a nozzle of the injection molding machine to a seat in an exterior wall of a chamber of the shutoff assembly, advancing an elongate stem through a first opening into the chamber, and flowing molten polymer into the chamber and out a second opening in the chamber and on to a mold or sprue bar. The mold may be decompressed by maintaining a movable body disposed in the chamber in a forward position with the elongate stem and allowing the molten polymer to flow out the first opening. The injection molding machine may be disconnected from the shutoff assembly by withdrawing the stem of the nozzle from the chamber through the first opening, allowing molten polymer downstream of the movable body to push the movable body into engagement with a sealing surface of a interior entry wall of the chamber, and disconnecting the nozzle from the seat.

摘要： An injection molding shutoff assembly that includes a chamber containing a movable body movable between rear and forward positions. In the rear position, the movable body provides a seal and prevents flow of molten plastic out the chamber inlet, called drool. When the movable body is in the forward position, one or more passages permit flow of the molten plastic around the movable body and to an exit in the chamber, leading to one or more molds. In an alternate embodiment, the apparatus also includes an elongate stem that maintains the movable body in the forward position allowing the injection molding system to decompress, thereby eliminating drool and decreasing downtime.

摘要： 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 (144, 146) 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).
摘要翻译：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）对准并且支撑其中的喷嘴（60,62）的安装的孔（144,146）。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）。

摘要： The present invention is a multiple-level stack mold for balancing the injection of molten plastic from an injection molding machine to a plurality of cavities, at least one cavity on each level of the multiple-level stack mold, for producing plastic parts facing in the same direction. Cavity plates are assembled in the multiple-level stack mold all facing in a first direction, and either core plates or plates having inserts thereon are assembled in the multiple-level stack mold all facing in a second direction. The clamping mechanism simultaneously moves the cavity plates and the core plates into engagement. Molten plastic is then evenly and simultaneously injected and distributed through a plurality of channels and passages, such that the flow of molten plastic is balanced throughout the system. Thereafter, the cavity plates and the core plates are simultaneously separated, thereby allowing removal of the resulting plastic parts, which are all facing in the same direction.

摘要： A nozzle controls flow of melt in injection molding equipment by passive actuation with opening and closing of a mold assembly. The nozzle comprises a valve pin having a pin passage therethrough movably supported within a nozzle passage and a contact arm transverse to and extending beyond the nozzle passage, the valve pin sealingly engaging the nozzle passage. Biasing means biases the valve pin to a closed position preventing passage of melt through the nozzle. The contact arm effects movement of the valve pin to an open position when closing of the mold assembly exerts a force on the contact arm to overcome the biasing means. A mold arrangement of plural mold assemblies comprises pairs of nozzles of the invention to control flow of melt through mating conduit segments between an injection unit and at least one mold assembly, the nozzles arranged and configured for seating engagement with abutment of the conduit segments.
