Description

Technical Field

[0001] The utility model relates to the technical field of compressor casting, in particular to a quick replacement structure of an aluminum liquid insulation furnace. Background Art

[0002] Existing compressors include piston compressors and scroll compressors, in which most of the compressor parts are manufactured by casting during production. Existing parts casting production is to quantitatively scoop aluminum liquid from the insulation furnace and cast it into a mold, and then cool it to obtain the part blank. After a certain amount of aluminum liquid is scooped from the insulation furnace, it is necessary to manually cut off the insulation furnace circuit and remove the current insulation furnace, replace it with a new insulation furnace full of aluminum liquid, and then close the insulation furnace circuit again to continue to maintain the continuous casting production operation of the parts. This method is complicated to operate and labor-intensive. Since the insulation furnace needs to maintain the temperature of the aluminum liquid in the furnace, there are certain safety hazards in manually cutting off or closing the insulation furnace circuit. For the existing aluminum liquid insulation furnace equipment, a method is designed that can complete the rapid switching of the insulation furnace to maintain the continuous and safe production operation of the compressor parts.
