Abstract
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.
