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： 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： 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： A nozzle for an injection molding apparatus is provided. The nozzle includes a nozzle body, a heater and a first gap seal surface. The nozzle body defines a nozzle body melt passage, that is adapted to be downstream from and in fluid communication with a melt source, and upstream from and in fluid communication with a gate into a mold cavity in a mold component. The heater is thermally connected to the nozzle body for heating melt in the nozzle body melt passage. The first gap seal surface is positioned on a structure that is connected at least indirectly to the nozzle body. The first gap seal surface is adapted to be separated by a gap with respect to a second gap seal surface on the mold component. The gap is sized to inhibit the flow of melt between the first gap seal surface and the second gap seal surface.

摘要： An injection molding system and injection molding method for making molded parts that include one or more planar heaters having a thin or a thick film resistive heater element coupled, secured, or releaseably secured to one or more sides of each of the one or more injection molding nozzles. The releasably secure coupling allows heater device to be visually inspected, tested, removed, and/or replaced. The planar heater device can have a support device patterned with a film electrical resistive path. The electrical resistive path can include any pitch or number of electrical resistance lines, such that a longitudinal uniform heat profile is generated along a melt flow channel of the one or more injection molding nozzles when the nozzles are in use. In some examples, the planar heater has more than one film resistive heater element that can be coupled to one or each side of a nozzle, with dielectric material interposed between the planar film resistive heater elements. This can allow for additional or alternative heating in various applications.
