Definitions

  • the invention relates to a method and a device for casting under a pressure generated by a gas phase according to the preamble of claim 1 and claim 4, respectively, and is used in foundry technology for the production of castings with high physical and mechanical characteristics from light metal alloys.
  • the known control block consists of a comparison block, the inputs of which are connected to a setpoint block and a temperature sensor, while its output is connected to the first inputs of two control blocks, the second inputs of which are connected to two setpoint blocks, the outputs of which are connected to the cooling or Heater are connected, as well as connected to the input of a control amplifier.
  • the output of the control amplifier is connected to the one circuit contact of a switch, the second contact of which is connected to a multivibrator.
  • the control block also contains control blocks for the movement, the gas flow processes and the metallurgical pretreatment, as well as a setpoint block for the temperature of the melt.
  • a major disadvantage of the known die casting device is the fact that if the melt in the furnace is exhausted and if a longer-lasting metallurgical and thermal pretreatment of the melt in the furnace is required, the casting process must be interrupted for a long time, which affects both productivity the device, as well as the quality of the castings, and this with increased energy losses.
  • Another disadvantage is that due to the many branches of the gas pipe system and the change in the direction of movement of the gas streams during filling and emptying, the melting level sometimes shakes and mixes with the gas phase, which leads to a deterioration in the casting parameters.
  • a pressure-tapping device which comprises: a casting machine with two movable furnaces, a mixing device for feeding the furnaces with melt, a gas line system for conveying the melt from the furnace through a pouring pipe to the mold cavity and a control block consisting of a comparison block, the inputs of which are connected to a setpoint block and a temperature sensor, while its output is connected to the first inputs of two control blocks, the second inputs of which are connected to two setpoint blocks and the outputs are connected to the cooling and heating devices, as well with the input of a control amplifier, the output of which is connected to one circuit contact of a switch, while a multivibrator (reed frequency meter) is connected to the second circuit contact of the switch.
  • the control block also contains control blocks for the movement, the gas flow processes and the metallurgical pretreatment as well as a setpoint block for the temperature of the melt.
  • the casting machine 1 contains a pantry 16, which has the left 2 or right 3 movable oven, and an equalizing chamber 17, which has a lower housing 18 and an upper housing 19, which are connected to one another by a releasable connection 26. These chambers 16 and 17 are separated from one another by an intermediate plate 20, on which the casting mold 21 is mounted in the area of the compensation chamber 17, which is connected to the pantry by one or more pouring tubes 22 which pass through the intermediate plate 20 and are immersed in the melt are.
  • the pouring tube 22 is pressed through the lower part of the mold 21 to the intermediate plate 20 and to the seal 23.
  • an extension 24 is worked out, on which a support 25 rests with play. This support 25 is mounted on the lower housing 18.
