Abstract: The embodiments of invention relate to a hot runner nozzle including at least one nozzle duct for a plasticized plastic, which ends in a nozzle tip and which can be temperature-controlled by a heater, wherein the hot runner nozzle can be attached to an injection molding tool or the like and wherein the heater and the nozzle duct are provided in a common housing of the hot runner nozzle laterally next to one another. The housing encompasses at least one material recess, which divides the housing adjacent to the nozzle duct and adjoining to the heater into housing regions, which are spaced apart from one another.

Abstract: The invention relates to a device for spraying-on of especially plastic mouldings, wherein at least one mould cavity to be filled, constructed in a tool is arranged laterally next to a central nozzle body, with at least one nozzle tip arranged in and/or on the nozzle body which projects outwards over the circumferential surface of the nozzle body and forms an injection channel for the mould cavity in a recess of the tool and/or the nozzle body, wherein at least one further recess is arranged in the area of the bottom of the nozzle body, wherein this recess is provided with at least one through opening which connects the recess to the circumferential surface of the nozzle body and wherein the nozzle tip can be inserted through the recess into the opening and detachably affixed there.

Abstract: A device for opening and closing injection nozzles in an injection moulding tool. The injection nozzle comprises a nozzle member, the nozzle opening of which can be opened and closed with a needle. The needle is stationarily arranged on a piston plate that is supported in a receptacle such that it can be moved in both axial directions similar to a double-action cylinder. A first work chamber is formed on the side of the piston plate which faces away from the needle and a second work chamber that can be acted upon with a fluid in order to actuate the needle is formed on the opposite side of the piston plate. The needle extends outward from the second work chamber through a recess in an end element that lies opposite of the piston plate.

Abstract: The maintenance of tools having functional parts located in their interior is facilitated considerably if these functional parts can be permanently observed and monitored without the tool needing to be dismantled. For this purpose coverable recesses are provided in the body of the tool.

Abstract: A heated channel for use between a clamping plate and a mold plate of a plastic injection machine. The heated channel includes a heated-channel member having longitudinal bores with cross bores for connecting the connecting and branching nozzles thereon. An insert member with material-guiding bores therein for providing the connection of the nozzles in the clamping plate and the mold plate is inserted into the longitudinal bore. The insert member is provided with grooves for receiving heating elements. Connecting elements for the radial and axial fixing of the heated-channel member and the insert member are inserted into the heated-channel member.
