摘要： A method and apparatus for removing melt from a stagnation zone in a melt conduit extending from a melt source to a mold cavity is provided. The stagnation zone may be created by the presence of a valve pin in the melt conduit for controlling melt flow therethrough. The apparatus includes a stagnation zone cleaner that is moveable through the stagnation zone for urging melt out of the stagnation zone.

摘要： An injection molding system includes a manifold and a valve gated hot runner nozzle. The gating mechanism includes an actuated valve pin, where the mold gate orifice is open when the valve pin is in a first position to allow melt to flow there through. The mold gate orifice is closed when the valve pin is in a second position to prevent melt from flowing there though. A flow control pin is disposed within the melt stream, either coaxially with the valve pin within the melt channel of the nozzle or within the manifold melt channel. The flow control pin has a head with a complementary geometry with that of the melt channel at a flow control surface. The flow control pin is raised and lowered by an actuation mechanism to constrict or release the flow of the melt stream independent from the movement of the valve pin.

摘要： An injection molding apparatus includes an injection piston that is slidable within a nozzle having a movable valve gate pin. The injection piston is movable from a retracted position to an extended position in order to force melt towards a mold cavity. A valve is located at a forward end of the piston to selectively block communication between a recess, which is provided in an outer wall of the piston adjacent the valve, and a melt chamber of the nozzle. Movement of the injection piston from the retracted position to the extended position causes the valve to close so that the predetermined volume of melt located below the valve is forced into the mold cavity, when the valve gate pin opens the mold gate.

摘要： An injection molding method, an injection mold and a valve gate device, in which a movable pin moves easily, without excess force being exerted thereto, to properly open and close a gate. Closing a gate 10B by a cylindrical movable pin 27 allows excess resin to easily return back to a resin conveying path side through an outer edge portion at the end of the movable pin 27, so that even a large-diameter gate 10B can be reliably closed by the movable pin 27 which can be easily moved due to reduced resin resistance on the movable pin 27.
