摘要： In a manifold, the valve pin has a sealing surface proximate its bottom end, which surface is engageable with a gate sealing surface to inhibit melt flow into the mold cavity. A first guidance and alignment structure is connected to the valve pin, and a second structure to the mould block upstream from the gate. Both structures include first and second guide surfaces of a diameter decreasing gradually in a downstream direction and first and second cylindrical alignment surfaces. The first guide surface is positioned immediately downstream from the first alignment surface, the second guide surface immediately upstream from the second alignment surface. The second guide surface is positioned to complete alignment of the valve pin with the gate prior to contact between the valve pin and gate. Further, it is positioned to engage the first alignment surface to maintain the valve pin in alignment with the gate during its movement towards the gate.

摘要： A melt transfer device for an injection molding apparatus includes a first shut off valve coupled to a first nozzle having a first melt channel. The first melt channel delivers a melt stream of moldable material to a second melt channel of a second nozzle, which is movable relative to the first nozzle. A second shut off valve is coupled to the second nozzle. The first shut off valve and the second shut off valve are retractable to open a melt transfer channel of the melt transfer device device to allow melt to flow between the first channel and the second melt channel.

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 being aligned with a first axis. A nozzle tip is received in a downstream end of the 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 provided at a downstream end of the nozzle tip including an outwardly extending flange having a peripheral edge that abuts an inner wall of the opening to align the 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 nozzle tip is flexible in order to compensate for the first axis and the second axis being out of alignment.

摘要： A control module (216) is attached to a machine platen (104) of an injection molding machine (100) The control module (216) is coupled to at least one sensor (110) that reports a value of a processing condition associated with an injection mold and is disposed within the injection mold. The control module (216) is also coupled to at least one controllable device (109) that varies the processing condition of the injection mold and is disposed within the injection mold. The control module (216) collects and processes sensor output, and provides a control signal to at least one controllable device (109). A display interface module (226) is linked to the control module (216). The display interface module accepts user-entered data set-points, provides the user-entered data set-points to the control module, and collects the processed sensor output from the control module for display to a user. Associated injection mold control methods are also presented.

摘要： In-line valve-gated nozzles for a single or multiple cavity applications wherein a valve-gated hot runner nozzle has a melt channel uniformly heated along the entire path. The valve pin is driven by an actuation device that is located adjacent to the nozzle to regulate the flow of melt. The actuation device has a linear motion and applies a uniform axial pressure on to the valve pin. This valve-gated nozzle can be linked directly to a machine nozzle, to an injection manifold or to a stack mold.

摘要： A nozzle (18) for an injection molding apparatus has a nozzle body (19) and a nozzle tip (24). A securing device (46) is used to secure the nozzle tip (24) to the nozzle body (19) via non-metallic threads (50) or threads (50) having a non-metallic coating that mate with complementary threads (54) on the nozzle body (19). In this example, through use of the non-metallic threads (50) or threads (50) having a non-metallic coating, the securing device (46) has a longer life than conventional securing devices by eliminating or substantially reducing thread galling.

摘要： A seal (44) is provided between a nozzle (20) and a manifold (12). The seal (44) provides a melt channel between an outlet (18) of manifold (12) and a nozzle channel (22). The seal (44) has higher thermal expansion coefficient than both the nozzle (20) and the manifold (12) to provide an improved seal between the manifold (12) and the nozzle (20) when the injection molding apparatus is at an operating temperature.
