摘要： Disclosed, amongst other things, is a molding apparatus and an injection molding process. The molding apparatus includes a positioner that is configured to regulate, in use, a relative position between a gate member and a nozzle of a melt distribution apparatus between a retracted position and an extended position for adjusting a volume of a nozzle melt reservoir that is definable between the gate member and the nozzle between a reduced volume and an expanded volume, respectively. The injection molding process includes regulating a relative position between a gate member and a nozzle of a melt distribution apparatus, with a positioner, into one of a retracted position and an extended position for adjusting a volume of a nozzle melt reservoir that is definable between the gate member and the nozzle between a reduced volume and an expanded volume, respectively.

摘要： A sprue bushing includes a melt channel for receiving a melt stream of moldable material from a source. The melt channel includes a first portion, a second portion and a decompression cavity located between the first portion and the second portion. A manifold having a manifold channel receives the melt stream from the melt channel of the sprue bushing and delivers the melt stream through the nozzle channels of several hot runner nozzles towards at least one mold cavity. A decompression device, which includes a rod having an enlarged head, is movable by an actuator to reciprocate within the decompression cavity between a retracted position and an extended position. Movement of the enlarged head from the extended position to the retracted position causes the suck back of the molten material in the hot runner nozzle and causes a portion of the molten material to be drawn toward the decompression cavity.

摘要： Disclosed herein, amongst other things, is a method ( 100) of operating an injection unit (110, 210) in a molding system comprising: extruding (102) a shot of a molding material with rotation of a screw (30) within a barrel (20) of the injection unit (110, 210): and retracting (104) the screw ( 30) within the barrel (20) such that during the extruding ( 102) of the shot of the molding material a melt pressure therein is kept below a pressure selected such as to substantially avoid drooling of the molding material through a nozzle (94) of a melt distribution system (92) that is associated with a mold (90).

摘要： A nozzle retention arrangement is provided for an injection molding manifold system, such as a hot runner manifold system. The nozzle retention arrangement couples an injection nozzle to a distribution manifold in a manner that locates the nozzle in its final operating position and applies an initial assembly load to retain the nozzle in position on the manifold to facilitate installation of a manifold system into a manifold plate. The nozzle retention arrangement may provide a compliant load application feature to limit sealing surface pressure between the nozzle and the manifold to prevent surface damage between the components, while also accommodating thermal expansion of the heated components during operation of the system. The nozzle retention arrangement may also provide a load control feature to prevent the machining quality of the nozzle bore in the manifold plate from determining the sealing load between the nozzle and the manifold.

摘要： An injection molding shutoff assembly includes a chamber containing a movable body that is biased to a rear position in the chamber by a magnet in the movable body. In the rear position, the movable body provides a seal and prevents flow of molten plastic through the assembly. When the movable body is in a 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. An injection molding machine nozzle tip has a beveled front end which, when in an engaged position, seals with an exterior seat of the assembly block defining the chamber and protrudes into the chamber to prop the movable body to the forward position. A portion of the assembly block proximate the opening for the nozzle tip is made of ferromagnetic material, while the rest is not.

摘要： An injection molding filtration apparatus having a filter, a decompression passage, and a filter check valve is used to filter molten polymer, while allowing for more complete decompression of the equipment downstream from the filter. The filter check valve and decompression passage are preferably internal to the filter element itself. In alternative embodiments, the decompression passage may be a separate bypass line that is arranged in a parallel configuration with an oppositely directed bypass check valve. Preferably, each of the check valves uses the molten polymer to push a movable body into a sealing engagement with an internal wall of the valve.
