Definitions

  • the present utility model relates to an automatic and metered supply device for molten metal intended for presses for metal injection in cold, horizontal and vertical chambers.
  • the main idea of the invention consists in coupling a siphon system for supply the cold room injection machines with molten metal.
  • All this set is coupled in an oven or a crucible in which the cylinder -4- sinks in its widest part into the interior of said crucible -1- which is provided with a series of communicating holes -8- which remain under the cylinder -4- and fill the crucible -1-, so that the said metal will enter the cylinder -4- by acting on the piston -3-, and its push will force the molten metal to leave by the lower outlet -5- and the corresponding tubing which remains subjected, in its external part to a heating produced by a torch -7- with propane gas or by electrical resistances which maintain it at the temperature of the metal, by driving it towards the cylinder injection -6-, and the metal is established by means of a limit switch caused by the movement of the injection piston -9- which is carried out in a conventional manner and with the known means of the injection presses to which this device has been assembled .
  • the shape can be any, as well as the adaptation of the support of the piston of the metering cylinder, whatever the shape, arrangement and height of the communicating holes inside the cylinder, no matter the shape and energy of the torch which heats the mat outlet nozzle iel and, of course, any size and material that is used to make the invention.
