Title (EN) METHOD AND DEVICE FOR LUBRICATING THE TOOLS OF A PRESSURE DYE CASTING MACHINE
(FR) PROCEDE ET DISPOSITIF DE LUBRIFICATION DES OUTILS D'UNE MACHINE A COULEE SOUS PRESSION
Abstract:
(EN) A method and a device designed for lubrication of the form tools of a die casting machine, when said tools have been opened up for a casting removal, comprising a storage tank (11) for a lubricant with ducts (10, 38, 39) to spray nozzles and a propellant gas source (17) connected to said ducts as well as programming automatics. The nozzles (40, 41) are at least partly mounted on a rotary chain wheel (28), the hub of which (19) is provided with one or a plurality of bores (35, 36), which successively are connected, when the wheel is rotating, to the branches of a branch system (9) of ducts in a stationary shaft (5), which supports said hub and said chain wheel, which branch system is fed with said mixture during a first phase of a lubrication cycle and solely with a propellant gas in order to clean off the duct system and the nozzles during a second phase of said lubrication cycle.
(FR) Procédé et dispositif permettant la lubrification des outils de formage d'une machine à coulée sous pression, lorsque lesdits outils ont été ouverts pour retirer un coulage, comprenant un réservoir de stockage (11) destiné à un lubrifiant, doté de conduits (10, 38, 39) menant à des pulvérisateurs, ainsi qu'une source (17) de gaz propulseur reliée auxdits conduits, ainsi qu'un système automatique de programmation. Les ajutages (40, 41) sont au moins partiellement montés sur une roue (28) à chaîne rotative, dont le moyeu (19) est doté d'une pluralité d'alésages (35, 36) lesquels sont connectés successivement lorsque la roue est en rotation, aux ramifications d'un système de ramifications (9) de conduits se trouvant dans un arbre fixe (5), lequel supporte ledit moyeu et ladite roue à chaîne, ledit système de ramifications étant alimenté à l'aide dudit mélange pendant une première phase d'un cycle de lubrification, et uniquement à l'aide d'un gaz propulseur, afin de nettoyer le système de conduits ainsi que les ajutages pendant une seconde phase dudit cycle de lubrification.
