Definitions

  • the invention relates to a method for operating a hot-chamber die casting machine, in the liquid metal shot by a back and forth movable plunger from a dipping into a metal bath Casting through the riser to a mouthpiece body and a nozzle tip conveyed into a mold and placed there under pressure becomes.
  • the invention also relates to a hot-chamber die casting machine for Implementation of such a procedure.
  • the object of the present invention is to remedy this situation and to provide a method of operating a hot chamber die casting machine and a correspondingly designed die casting machine to propose, with which relatively safe the air out of the mold and can be removed from the casting system.
  • a hot chamber die casting machine is suitable for carrying out the new method.
  • the one with the riser to the nozzle tip rising channel in the mouthpiece body and with one in the area of Nozzle tip arranged metal sensor is provided, however, the Metal sensor deviating from the proposal according to WO 95/33588 to the Bottom of the mouthpiece body is attached.
  • the metal sensor of the in the Vorphilllphase the casting system slowly filling liquid metal flooded and it can be a sensitive regulation take place.
  • have mouthpiece body common hot-chamber die casting machines have a slope of about 5 °, which can be exploited to the metal in this inclined mouthpiece channel slowly by the forward movement of the casting piston to rise to the metal sensor.
  • Fig. 1 shows first that the total number 1 provided casting system from a furnace 2, not shown in detail a tempered extraction chamber 3 is in the up to the level 4 liquid metal 5 is located.
  • a tempered extraction chamber 3 is in the up to the level 4 liquid metal 5 is located.
  • Metal bath immersed a casting container 6, which has a cylindrical casting chamber 7 and a movable up and down casting piston 8 and a with the casting chamber 7 has associated riser channel 9.
  • the Rising channel 9 opens into a mouthpiece body 10, which in the end the riser 9 provided connection piece 11 of the casting container. 6 used and as well as this is heated, but not shown in detail is.
  • the casting chamber 7 is also provided with a connection opening 12 for Metal bath 5 provided, which in the position shown retracted the casting piston 8 is released.
  • the casting piston 8 in turn is about a piston rod 13 controlled driven, the intended Casting piston drive is not shown.
  • the mouthpiece body 10 is provided with a nozzle tip 14 inserted in it provided, which is apparent from Fig. 2.
  • Fig. 2 is also around the Mouthpiece body 10 arranged around heater 15 indicated.
  • a metal sensor 16 which from the bottom in the Mouthpiece body 10 is inserted and via a connecting cable 17 with a control device 18 is in communication, which in turn is not closer shown manner is connected to the drive for the casting piston 8.
  • Fig. 1 To Fig. 1 is still to be noted that the mouthpiece with the nozzle tip 14 is attached to the feed system 19 for the mold 20, which consists of a on the fixed mold clamping plate 21 of the die casting machine not shown further clamped solid mold half 22 and from the not shown on the attached to the die-casting movable platen movable mold half 23 is constructed.
  • This form 20 is known in the art Way provided with ventilation channels and it is in Fig. 1 in the closed Condition drawn.
  • the closed mold according to FIG. 1 is now opened according to the new method for removing the workpiece which is still in the mold.
  • This mold opening occurs according to FIG. 3 at time zero on the time axis t extending to the right.
  • the casting piston 8 is now moved downwards by its drive from the position shown in FIG. He closes the connection opening 12 to the metal bath 5 and pushes the present in the casting chamber 7 and in the adjacent riser channel 9 to the level 4 liquid melt material through the riser channel upwards into the slightly rising to the mold 20 channel 24 of the mouthpiece 10.
  • the liquid Metal melt 5 reaches, as indicated in FIG.
  • the metal sensor 16 which is inserted from below into the channel 24 of the mouthpiece 10 and flooded at a horizontally extending level 25, so that a signal can be emitted when the liquid melt 5 at the metal sensor 16 or - after a further short period of time to be determined empirically - at the nozzle tip 14 to the horizontally extending maximum level 25a is present.
  • This time, or the time at which the molten metal 5 reaches the metal sensor 16, is now utilized together with "mold closed" as a start signal for the rapid mold filling. In the embodiment of FIG. 3, this is the case at time t after two seconds.
  • the mold itself is closed at time t F , so that afterwards - at the time of the lapse of three seconds - the mold filling process can be used at high speed in the manner already known.
