摘要： A nozzle is provided for an injection molding apparatus. The nozzle includes a nozzle body, a heater, a tip, a tip surrounding piece. The nozzle body defines a nozzle body melt passage, which has an inlet that is adapted to be downstream from and in communication with a melt source. The heater is connected to said body for heating melt in said nozzle body melt passage. The tip defines a tip melt passage that is downstream from and in communication with said nozzle body melt passage. The tip melt passage has an outlet that is upstream from a gate in a mold component. The tip includes a tip sealing surface. The tip surrounding piece includes a first tip surrounding piece sealing surface. The first tip surrounding piece sealing surface and said tip sealing surface are separated by a gap. The gap is sized to inhibit the flow of melt between said first tip surrounding piece sealing surface and said tip sealing surface.

摘要： A seal is provided between a nozzle and a manifold. The seal provides a melt channel between an outlet of the manifold and a nozzle channel. The seal has higher thermal expansion coefficient than both the nozzle and the manifold to provide an improved seal between the manifold and the nozzle when the injection molding apparatus is at an operating temperature.

摘要： The method and apparatus of the present invention includes a computer implemented injection molding configuring subsystem which enables a customer to interactively specify and design a system using a mix of parameters that the customer specifies and are manufacturing process determined. The configuring subsystem is connected to a computer network such as the Internet. The method and apparatus of the present invention further includes a computerized business and processing subsystem in communication with the configuring subsystem. The computerized business subsystem automatically provides a cost and schedule for a system configured by the configuring subsystem and additionally processes an order for the system. The processing subsystem automatically processes the customer's inputs and generates drawings for the configured system. Prior to receiving the customer's order, hot runner system components may be partially manufactured in a first phase and placed in inventory. The partially manufactured hot runner components may then be removed from inventory after receiving a customer's order, and further manufactured and assembled in accordance with the customer's parameters in a second phase.

摘要： A locking mechanism for locking a valve pin of a nozzle of an injection molding apparatus in an extended position includes a generally oblong detent coupled to a pin. The pin extends through an aperture located at a first end of the detent to secure the detent to an inner wall of a recess, which is located adjacent the piston-receiving cavity of the valve pin. The detent is pivotable about the pin to rotate a second end of the detent into abutment with a return surface of the piston to restrict movement of the valve pin.

摘要： A nozzle for an injection molding apparatus is provided. The injection molding apparatus has a mold component that defines a mold cavity and a gate into the mold cavity. The nozzle includes a nozzle body, a heater, a tip, a tip surrounding piece and a mold component contacting piece. The nozzle body defines a nozzle body melt passage therethrough, that is adapted to receive melt from a melt source. The heater is thermally connected to the nozzle body for heating melt in the nozzle body. The tip defines a tip melt passage therethrough, that is downstream from the nozzle body melt passage, and that is adapted to be upstream from the gate. The tip surrounding piece is removably connected with respect to said nozzle body. The mold component contacting piece is connected with respect to the nozzle body. The material of the mold component contacting piece has a thermal conductivity that is less than at least one of the thermal conductivity of the material of the tip and the thermal conductivity of the material of the tip surrounding piece.

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。
