<p>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.</p> |
