摘要： Valve gated multi-cavity injection molding apparatus for five layer molding having actuating mechanisms for reciprocating elongated valve members between four different positions. Each actuating mechanism has a front and a rear aligned cylinders, a first piston connected to the head of one of the valve members in the front cylinder and second and third pistons in the rear cylinder. The third piston has a stem portion which extends forwardly through the second piston into the front cylinder. Hydraulic pressure from four hydraulic lines connected to each actuating mechanism reciprocates each elongated valve member between the different positions. In the first closed position, the front end of the valve member is seated in the gate. In the second position, the front end of the valve member is retracted sufficiently to allow an initial amount of PET to flow from an outer annular melt channel through the gate. Then the valve member is retracted further to a third position to allow simultaneous flow of the PET and a barrier material from an inner annular melt channel. Then the valve member is retracted to a fully open position which allows the simultaneous flow of PET from a central melt channel. When the cavity is almost filled, the valve member returns briefly to the second position for filling before returning to the closed position for ejection.
摘要翻译：用于五层模制的阀门浇口多腔注射成型装置，其具有用于在四个不同位置之间的往复式细长阀构件的致动机构。每个致动机构具有前和后对齐的气缸，第一活塞连接到前气缸中的一个阀构件的头部以及后气缸中的第二和第三活塞。第三活塞具有杆部，其向前延伸穿过第二活塞进入前缸。连接到每个致动机构的四个液压管路的液压压力使每个细长阀构件在不同位置之间往复运动。在第一关闭位置，阀构件的前端位于门中。在第二位置，阀构件的前端充分缩回以允许初始量的PET从外部环形熔体通道流过门。然后，阀构件进一步缩回到第三位置，以允许PET和阻挡材料从内部环形熔体通道同时流动。然后，阀构件缩回到完全打开的位置，其允许从中心熔体通道同时流动PET。当空腔几乎被填充时，阀构件在返回到关闭位置之前短暂返回到第二位置以进行填充。

摘要： Apparatus for selectively controlling the flow of at least three melt material streams through the nozzle of a machine for injection molding multi-layer plastics articles. The nozzle has, for each stream, a flow passageway terminating at an exit orifice. Sleeve means having an internal axial material flow passageway, communicate with the central channel and with one of the flow passageways and are movable axially and/or rotationally to block and unblock at least two orifices. Each flow passageway can include material flow directing means for balancing stream flow around the passageway and its exit orifice, and a tapered portion adjacent its orifice. Preferably, the orifices are fixed. Means can pressurize melt material in a flow passageway between the flow directing means and the associate orifice so that the start of flow of the material through the orifice is substantially uniform thereabout. Co-injection nozzle means for multi-polymer injection molding and blow molding machines are provided having valve means and/or one or more of the afore-mentioned features.
