Abstract (en)
[origin: WO8601442A1] For cooling, cleaning and/or lubrication purposes, a device (10) for wetting mould surfaces (12) is arranged on a pressure-casting machine, equipped with a spray head (10), provided with directionally orientable spray nozzles (42), in which liquid passages (44) and settable throttle valves (46) are arranged. In order to design a device of this type so that it is suitable for the specific treatment of a very wide range of shaped surfaces, without it being necessary to undertake, for each new change in shape or for each new application, costly adjustments, and also to ensure a faster automatic pressure casting operation without any rejects and avoid unduly high protection and storage costs, the spray head (40) consists of a fixed part (48) as well as of an easily exchangeable spray nozzle carrier (54) which lies against the latter as a seal, whereby the fixed part contains the passages (44) and the throttle valves operating in conjunction with the passages, and is connected with the movable holding elements and the spray nozzle carrier as a relatively simple and inexpensive component equipped only with the spray nozzles (42) and, if applicable, displacement elements for moving the throttle valves (46).
