  • An adjustable throttle valve is provided for each spray nozzle in order to specifically influence the amount of compressed air and / or liquid passed on to the spray nozzles.
  • the spray head itself is brought in front of the mold surface to be sprayed by means of movable holding elements.
  • Such a spray head can not only be used on a single specific shape, but can also be used on molds of different designs due to the adjustability of its nozzle arrangement.
  • adapting the spray nozzle arrangement to a new shape, in particular adjusting the direction of the individual nozzles and adjusting the associated throttle valves is very time-consuming and can only be determined empirically. This means that after a first rough adjustment, a die casting process usually has to be carried out, the quality of which then decides, if necessary, on new readjustments of the spray head. Such a procedure is not only material-intensive, but also very time-consuming.
  • the throttle valves arranged in the known spray head are "static" valves, which is intended to express that the maximum valve cross section that has been set is always the same both during the spraying process and before and after the spraying.
  • Such "static" valves tend to clog and stick, especially when a spray head has not been used for a long period of time and residues of lubricant in the relatively small valve cross-sections gum up.
  • the nozzles are fixed in a middle plane between the mold halves.
  • the spray head consists of a tubular frame on which the nozzles are either mounted in one direction or offset by 180 ° in the other direction, which means that only a spray jet running at right angles to the level of the spray head is possible. Uniform compressed air is emitted from the inside of the frame of the spray head, which is equally effective for all spray nozzles. A different spray direction and a different one Spray pressure or a different spray quantity is not possible.
  • the lubricant is fed to the nozzles via flexible hoses which have to be mounted on the spray head carrier each time the spray head is replaced and which are exposed to considerable wear during hot operation in the die casting machine.
  • the spray head carrier does not contain any valves or presets. The lubricant is simply distributed to each spray nozzle via the hoses from the spray head carrier.
  • the invention has for its object to provide a device for wetting mold surfaces with a liquid for cooling, cleaning and / or lubricating purposes in such a way that it is suitable for the targeted treatment of different mold surfaces, without each new change of shape or each Repeated reuse of a mold, expensive adjustment work has to be carried out, a fast automatic die-casting operation without rejects is ensured and excessive production and storage costs are avoided.

Abstract

Un dispositif (10) pour humecter la surface (12) de moules est agencé sur une machine à coulée sous pression (14) à des fins de refroidissement, de nettoyage et/ou de lubrification. Le dispositif (10) comprend une tête d'arrosage (40) pourvue de pulvérisateurs (42) orientables, dans laquelle sont agencées des conduites de liquide (44) et des soupapes d'étranglement (46) réglables. Afin d'obtenir un traitement approprié de surfaces de moules aux formes les plus diverses, sans qu'il soit nécessaire d'effectuer des ajustements coûteux à chaque fois qu'un nouveau moule est utilisé ou qu'un ancien moule est à nouveau utilisé, tout en assurant une coulée sous pression rapide et automatique sans rebuts et en évitant des coûts excessifs de production et de stockage, le dispositif est construit avec une tête d'arrosage (40) composée d'une partie rigide (48) et d'une partie de support des vaporisateurs (54) hermétiquement connectée à la première et aisément remplaçable. La partie rigide comprend les conduites (44) et les soupapes d'étranglement qui coopèrent avec celles-ci, et est connectée aux élémments mobiles de retenue, alors que le support des vaporisateurs est une pièce relativement simple et peu coûteuse comprenant uniquement les vaporisateurs (42) de même que, le cas échéant, des éléments de réglage pour régler les soupapes d'étranglement (46).
