A nozzle 10 for an injection mold has a nozzle body 12 which can be mounted on a mold or manifold and in which at least one duct 22 for molten material is provided which opens at a terminal side at, or in, a nozzle tip 26. In order to be able to realize extremely small pitches in two independent directions in space, the nozzle body 12 has at least one substantially plane lateral surface 14, 15 which carries or accommodates in a plane 2D-type joining and/or arrangement a heating and/or cooling device 28, 28′ for the molten material. In a special embodiment, the nozzle 10 within in a row of nozzle R are located next to each other in very close relationship, and two opposing lateral surfaces S or the row of nozzles R are provided with heating and/or cooling devices 28, 28′, which are adapted to be connected in groups to a heating or cooling circuit via a common external terminal.
A nozzle (10) for an injection mold comprising a nozzle body (12) including a mounting structure on an end thereof having a longitudinal axis that is adapted to be mounted on a mold or manifold, the nozzle body including at least one duct (22) for a melt flow which duct opens endwise at or in a nozzle tip (26), and comprising a heating and/or cooling means (28, 28′) for the melt flow, the nozzle body (12) having at least one substantially plane lateral face (14, 15) which is generally parallel to the longitudinal axis of the mounting structure and supports or accommodates said heating and/or cooling means (28, 28′) in a full-faced engaging and/or joining arrangement, the at least one substantially plane lateral face (14, 15) being provided with the at least one heating and/or cooling means.
A nozzle (10) for an injection mold comprising a nozzle body (12) adapted to be mounted on a mold or manifold, the nozzle body including at least one duct (22) for a melt flow which duct opens endwise at or in a nozzle tip (26), and comprising a heating and/or cooling means (28, 28′) for the melt flow, the nozzle body (12) having two opposing substantially plane lateral faces (14, 15) each of which supporting or accommodating the heating and/or cooling means (28, 28′) in a full-faced engaging and/or joining arrangement, each of the substantially plane lateral faces (14, 15) being provided with the heating and/or cooling means (28, 28′).
A nozzle assembly for injection molds comprising at least two nozzles (10), each having a nozzle body (12) adapted to be mounted on a mold or manifold, each nozzle body including at least one melt flow duct (22) which opens endwise at or in a nozzle tip (26), and comprising a heating and/or cooling means (28, 28′) for the melt flow, wherein the nozzles (10) form a nozzle row (R) in the form of a flat body (K) within which they are disposed in close packing parallel to each other, the flat body (K) having at least one substantially plane lateral surface (S) supporting or accommodating the heating and/or cooling means (28, 28′) in a full-faced engaging and/or joining arrangement, the substantially plane lateral face (14, 15) being provided with the heating and/or cooling means (28, 28′), the total thickness (D) of the flat body (K) being substantially determined by the thickness (width B) of the nozzle bodies (12).
