Description

technical field [0001] The invention relates to the technical field of low-pressure casting, in particular to an electromagnetically driven low-pressure casting forming heat balance device. Background technique [0002] In the electromagnetic-driven low-pressure casting molding equipment, many parts need to be cooled, and many parts need to keep the molten aluminum warm to prevent the solidification of the molten aluminum and ensure the continuity of the casting filling process. In the electromagnetic-driven low-pressure casting molding equipment, the insulation and cooling parts include: 1) The aluminum liquid in the aluminum liquid holding furnace needs to be maintained at 690-730 °C, and it can be adjusted; 2) The aluminum liquid in contact with the electrode part needs to be kept constant Temperature, due to the extremely small thermal resistance of the metal electrode, under a large temperature gradient, the heat dissipation capacity is greater than the heat compensatio...

Problems solved by technology

In the existing technology, the electromagnetically driven low-pressure casting equipment mainly relies on increasing the insulation layer to solve the problem. The effect is not good, and the temperature of the system is frequently unbalanced, making it difficult to ensure the continuous operation of the equipment and the quality of the molded castings.
