Abstract
For cooling, cleansing and/or lubricating purposes on a pressure casting machine 14 there is arranged an apparatus 10 for wetting mold surfaces 12 by spraying pressurized fluid thereon, which comprises a spraying head 40 provided with spraying nozzles 42 apt to be adjusted as regards direction, in which spraying head channels 44 and adjustable throttle valves 46 are disposed. To form such apparatus such that it is suited for the selective treatment of the different mold surfaces, no expensive adaptation operations being necessary with each change of mold and/or each re-use of such mold, that moreover a rapid automatic pressure casting operation is guaranteed and that high manufacturing and storage costs are avoided. The spraying head 40 is composed of stationary member 48 and an easily exchangeable spraying nozzle carrier 54 sealingly resting thereagainst, the stationary member containing channels 44 and throttle valves co-acting with said channels and being connected to the movable holding elements, and the spraying nozzle carrier as a relatively simple and inexpensive constructional member essentially being only provided with spraying nozzles 42 and, if necessary, adjusting elements for adjusting throttle valve 46.
