Description
Technical Field
[0001] The utility model belongs to the field of aluminum alloy casting, in particular to an aluminum alloy quantitative furnace adopting an electromagnetic power filling system. Background Art
[0002] At present, traditional pneumatic aluminum alloy dosing furnaces all use one end of the riser tube to insert into the aluminum liquid in the dosing furnace, and the other end of the riser tube is connected to the casting machine. Then the pressurization system fills compressed air into the furnace of the dosing furnace. The air pressure in the furnace of the dosing furnace increases, and the aluminum liquid is forced to rise upward along the bottom port of the riser tube in the aluminum liquid, flow into the casting machine, and fill into the casting mold to complete the filling.
[0003] The above-mentioned existing pneumatic aluminum alloy quantitative furnace uses compressed air as a driving source to drive the aluminum liquid into the mold for filling during the casting process. Due to the temperature changes of the compressed air, the changes in the liquid level during the filling process, and the expansion of the air, it is difficult to achieve the predetermined accuracy in pressure control. When the aluminum liquid is pushed, the liquid level of the aluminum liquid will fluctuate with the changes in the air pressure, and the quantitative accuracy of the aluminum liquid cannot be accurately controlled.
[0004] In the above-mentioned existing pneumatic aluminum alloy quantitative furnace, each mold needs to undergo a cycle of inflation and deflation during the casting process. Compressed air is repeatedly filled in, and the water vapor in the compressed air penetrates into the molten aluminum, causing the gas content of the molten aluminum to exceed the standard. A large amount of oxide slag will also be produced in and on the surface of the molten aluminum due to repeated filling of air. Utility Model Content
[0005] In view of the above technical problems, the purpose of the utility model is to provide a new aluminum liquid pressurized driving technology, namely electromagnetic power filling technology, when the aluminum liquid is quantitatively measured in the aluminum alloy quantitative furnace. The entire pressurized filling process no longer requires compressed air, and the quantitative filling process of aluminum alloy casting is completely carried out by controllable electromagnetic thrust.
[0006] The electromagnetic power filling system used in the utility model is a device for conveying aluminum alloy fluid. Its principle is to use the electromagnetic driving force generated by the combined action of alternating current and magnetic field to directly act on the conductive aluminum liquid to cause it to move in a directional manner. Driven by the electromagnetic force, the aluminum liquid flows into the mold along the flow channel to complete the filling.

[0010] The control system 3-1 of the electromagnetic power filling system 3 is started, and the electromagnetic coil 3-2 is sleeved on the outside of the ceramic tube 3-3. After the electromagnetic coil 3-2 is energized, the aluminum liquid in the ceramic tube 3-3 generates thrust. The aluminum liquid 2-3 in the insulation furnace passes through the ceramic tube 3-3 and is pushed by the thrust of the electromagnetic power filling system 3, and enters the injection barrel 1-3 along the aluminum liquid flow channel 2-4. The injection rod 1-4 then presses the aluminum liquid in the injection barrel 1-3 into the mold 1-5 for casting.
