Description

Technical Field

[0001] The utility model relates to the technical field of aluminum ingot processing, in particular to an aluminum ingot casting mold demoulding device for a large aluminum ingot. Background Art

[0002] Aluminum is a silvery-white metal, and its content in the earth's crust ranks third after oxygen and silicon. Aluminum has a low density, only 34.61% of iron and 30.33% of copper, so it is also called a light metal. Aluminum is the non-ferrous metal with the second largest output and usage in the world after steel. The density of aluminum is only 2.7103g / cm 3 , which is about 1 / 3 of the density of steel, copper or brass. Because aluminum is light, it is often used in the manufacture of land, sea and air transportation vehicles such as cars, trains, subways, ships, airplanes, rockets, and spacecraft to reduce their own weight and increase their load capacity.

[0003] During the processing of aluminum ingots, the corresponding mold demoulding is required. There is an aluminum ingot mold demoulding device with a Chinese patent publication number of CN210702493U. When it is used, the adjusting rod is rotated counterclockwise, and the adjusting rod drives the connecting parts to move in opposite directions. The angle between the connecting rod and the adjusting rod gradually decreases, and the connecting rod drives the lifting block to descend until the lifting block is out of contact with the lifting plate. Then the aluminum ingot mold demoulding device is placed directly below the liquid outlet of the ash roasting machine, and the aluminum liquid enters the containing frame and is shaped; the adjusting rod is rotated clockwise, and the two nuts on the adjusting rod move toward the middle part of the adjusting rod at the same time, so that the angle between the connecting rod and the adjusting rod gradually increases, and then the lifting block is pushed upward. The lifting block pushes the lifting plate during the upward movement, and the formed aluminum ingot is above the lifting plate. When the lifting plate rises, it pushes the aluminum ingot to move upward until the aluminum ingot is out of the containing frame, thereby completing the demoulding of the aluminum ingot.

[0004] However, the support base of the device is fixed to the containing frame, which makes internal maintenance inconvenient and has poor practicality. Utility Model Content
