摘要： This invention relates to an improved heated nozzle probe for injection molding and an improved stack molding system in which it is used. Each nozzle probe has an inner helical shaped heating element which extends into the pointed tip, and a separate outer one which does not. In addition to providing more heat to the pointed tip, this has the advantage that a standard unit can be used for various applications. In the stack molding system, two heated nozzles are arranged in alignment to bridge the parting line and the pointed tip of only the downstream one is heated. Combined with tapering the aligned gates to gradually increase in diameter in a downstream direction, this has been found to considerably reduce stringing and drooling problems as the mold opens for ejection.
摘要翻译：本发明涉及一种用于注射成型的改进的加热喷嘴探针和其中使用的改进的叠层模制系统。每个喷嘴探针具有延伸到尖端的内螺旋形加热元件，以及不是的单独的外部加热元件。除了为尖头提供更多的热量之外，这具有以下优点：标准单元可用于各种应用。在堆叠成型系统中，两个加热的喷嘴排列成对齐以桥接分型线，并且只有下游的尖端被加热。结合使对准的门逐渐变细以在下游方向上逐渐增加直径，已经发现，当模具打开用于喷射时，已经发现这显着地减少了拉紧和流口水问题。

摘要： This mould assembly for elastomers is of the type comprising a center block whose temperature is regulated. The block has means for injection of the elastomer into each mould cavity fed with elastomer by a nozzle of the injection device of the press. The center block has projections which are mounted on the block, or are part of the same material as the block, and project from two of opposite sides of the block. Small nozzles for directly injecting the elastomer into the mould cavities are detachably secured on the ends of the projections and adapted to cooperate with adjacent sections of at least two moulds in two or more sections which are disposed on the opposite sides of the center block. Means distinct from those of the block are provided for separately controlling the temperature of the projections and of the small nozzles. Means are provided for controlling the flow through the small nozzles. Means are provided for compensating for the expansion of the block and the moulds. The mould assembly further comprises a special nozzle for feeding elastomer to the block, the temperature of the special nozzle being controllable.

摘要： A system for injecting synthetic-resin material into an injection-molding assembly having ganged mold cavities, i.e., a multiple-separation mold in which the mold chambers to be charged are located one behind or above another in the mold-opening or mold-closing direction, wherein the mold-charging duct is so constructed and arranged that, from the outlet of the duct, the injectable material flows along equal-length paths to all of the chambers.

摘要： An injection mold (100) including a core plate assembly (200), a cavity plate assembly (400) and a stripper plate assembly (300) arranged between the core and cavity plate assemblies (200, 400). The mold (100) includes a plurality of mold stacks (MS) with a molding configuration, in which the mold stacks (MS) are closed to define molding cavities. A gap (G) is provided between the core plate (210) and the stripper plate (310) when the mold (100) is in the molding configuration, such that a clamping load (CL) applied to urge the core plate (210) toward the cavity plate (410) is directed substantially entirely through the mold stacks (MS).

摘要： An injection-molding machine includes a stack mold having a snorkel supplying melt to a central part of the stack mold. A biased movable part of the snorkel and a nozzle of an injection unit can be pressed against one another during the injecting process, wherein a position of the injection unit can be fixed in the longitudinal machine direction, when the stack mold is in a position for performing a compression molding stroke. A bias and a stroke executable by the movable part of the snorkel can be adjusted, so that the nozzle and the snorkel remain pressed against each other at least while the compression molding stroke is executed during the injection process. The position of the injection unit is held during an injection process while the compression molding stroke is executed

摘要： The present invention relates to a method for use in injection molding with the capability to have precise and adjustable control of the molten plastic flow when molding at least two (2) non-identical (i.e. with more than 50% difference in weight or form) or identical complex-shaped and intricate plastic parts at the same time, utilizing a mold with at least two (2) parting layers via a standard conventional injection machine. This invention incorporates the principle of having two (2) valve pins in which their movements are back-to-back and can be independently opened and closed as controlled by stepper, servo or linear motors linked to a separate independent tool controller. The two (2) valve pins are positioned at the floating half of the mold for sequential, stack or multi-layer mold with multiple cavities.
