摘要： The invention refers to an injection molding apparatus comprising a manifold (12,12a) having a first manifold channel (14,14a) for a first melt stream and a second manifold channel (24,24a) for receiving a second melt stream, said first melt stream exiting said manifold (12,12a) through a first manifold outlet and said second melt stream exiting said manifold (12,12a) through a second manifold outlet (29,29a), a first nozzle channel (52) for receiving said first melt stream from said first manifold outlet and a second nozzle channel (54) for receiving said second melt stream from said second manifold outlet (29,29a), a mold cavity (60) for selectively receiving the first and second melt stream from the nozzle (30,30a) through a mold gate, and an injection piston (70) being slidable between a retracted position and an extended position the injection piston (70) extending through an injection manifold channel (80) located between said first manifold outlet of said manifold (12,12a) and said first nozzle channel (52). The injection piston (70) is slidable through said injection manifold channel (80) and having an outer wall for selectively blocking the communication between said first manifold channel (14,14a) and said injection manifold channel (80), wherein movement of said injection piston (70) towards said extended position forces melt located in a melt chamber (78) of said first nozzle channel (52) to flow into said mold cavity (60).

摘要： An injection molding system is disclosed. The system includes a multiple valve gated nozzle (100). The flow through each valve gate (114,116) is determined by individually operated valve pins (110,112). Each valve pin (110,112) is independently controlled by a separate actuation unit (118,120). In order to achieve a tight pitch between the valve pins (110,112), the actuation units (118,120) are placed in a stacked configuration, with the valve pin (110) controlled by the upper actuation (118) unit passing through the lower actuation unit (120). The valve pin (112) of the lower actuation unit (120) is offset from a center of the upper actuation unit (118) to allow for the unimpeded passage of the valve pin (110) from the upper actuation unit (118) through the lower actuation unit (120).

摘要： An improved melt distribution system and method is provided for a multi-level stack mold having three or more moving platens. The injection machine communicates with a bifurcated sprue bar for providing pressurized melt through the first moving platen to a central distribution manifold in the second moving platen. From the central distribution manifold, the flow of pressurized melt is distributed to the first and third platens for transfer to a plurality of mold cavities.

摘要： An injection molding apparatus includes a manifold and a nozzle, which is received in an opening in a mold plate, including a nozzle channel for receiving the melt stream from the manifold channel, the nozzle channel bein g aligned with a first axis. A nozzle tip is received in a downstream end of t he nozzle. The nozzle tip includes a melt channel for receiving the melt stream from the nozzle channel of the nozzle. A valve pin guiding portion is provid ed at a downstream end of the nozzle tip including an outwardly extending flang e having a peripheral edge that abuts an inner wall of the opening to align th e melt channel with a second axis through a mold gate. A valve pin is movable through the melt channel to selectively open the mold gate. Wherein the nozz le tip is flexible in order to compensate for the first axis and the second axi s being out of alignment.

摘要： The present invention is an injection molding apparatus having a cast manifold. The manifold is made from a cast block and includes at least one pipe and a junction component fixed therein. The junction component has an axial bore having a first end and a second end, and at least one radial bore fluidly connected to the axial bore and having an opening to an outer surface of the junction component. A melt is introduced into the manifold and travels through the radial and axial bores of the junction component and through at least one pipe connected thereto to an injection molding nozzle for injection into a mold cavity. A manifold of the present invention may have a plurality of pipes and junction components to form a branched multi-level cast manifold.

The contacts between tip, alignment piece, tip surrounding piece and mold component are axially proximate the gate. The alignment piece contacts the tip surrounding piece to align the alignment piece with respect to the tip surrounding piece. The tip surround piece contacts the mold component to align the tip surrounding piece with respect to the gate. The nozzle body defines a nozzle body melt passage adapted to be in fluid communication with and downstream from the runner. The tip defines a tip melt passage downstream from and in fluid communication with the nozzle body melt passage. An Independent claim is included for injection molding apparatus.
