Description

technical field

[0001] The invention relates to a die-casting nozzle, in particular a high-temperature channel nozzle, which is intended to be arranged in a die-casting mold which, depending on its structure, has a plurality of plates and has at least one rear plate or mold fastening base on its fixed mold side. and a distributor plate with at least one cavity plate on its mold side, on the mold pocket of which the nozzle tip is inserted, wherein the high temperature channel nozzle is designed with a housing collar and in a central material tube There is a flow channel for the material melt that opens into the nozzle tip, as well as connections for the heating system and temperature sensors. Background technique

[0002] A die-casting nozzle of this type is known from DE 195 42 237 B4, which is designed as a high-temperature channel nozzle with an integrated electrical heating element and has a central hole as a flow channel for conveying the thermoplastic melt up to the noz...

Embodiment Construction

[0021] The die-casting mold 1 shown in the drawing consists of a plurality of plates on its fixed mold side I and on its mold side II which has a separable mold part which has a cavity plate 2 in which Machining out model cavity 3 (see figure 1 ). Among these plates are shown on the fixed mold side I a back or mold fastening base plate 4 , a distributor plate 5 with not shown flow channels, and a frame plate or intermediate plate 6 . In the die-casting mold 1 from the front, starting from the mold side II, an die-casting nozzle, which is designed as a high-temperature channel nozzle 7 in the exemplary embodiment, is inserted. This nozzle has a flow channel 9 leading to the nozzle tip 8 in a centered sleeve for the metal melt introduced from the distributor plate 5 according to the arrow 10 in the injection direction. Come out from the nozzle tip 8 and flow into the model cavity 3 of the cavity plate 2, as by figure 1 as visible.
