Embodiment Construction

[0028] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited by the embodiments.

[0029] Such as Figure 1 to Figure 3 As shown, the aluminum ingot demoulding device of the present invention mainly comprises: casting mold 10, ejection mechanism 15, lifting mechanism 19 etc., concrete structure is as follows:

[0030] Ejection mechanism 15 is made up of top plate 14, No. 2 oil cylinder 16 and No. 2 guide device 18. Top plate 14, No. 2 oil cylinder 16 and No. 2 guide device 18 are installed in the middle part of fixed frame 17, and No. 2 oil cylinder 16 is located in the middle, guiding The device 18 is symmetrically arranged on both sides of the No. 2 oil cylinder 16, and the No. 2 oil cylinder 16 is connected with the top plate 14 and the fixed frame 17 in a hinged manner. Lifting mechanism 19 is made of lifting frame 4, roller 5, No. 1 oil cyl...

Abstract

The invention relates to the field of aluminum ingot casting, and particularly relates to a demolding device for producing a large aluminum ingot and a demolding method. An ejection mechanism of the device is composed of a top plate, an oil cylinder II and a guide device II, wherein the top plate, the oil cylinder II and the guide device II are installed in the middle of a fixed rack; a lifting mechanism is composed of a lifting rack, rollers, an oil cylinder I and a guide device I, wherein the rollers are symmetrically arranged on the upper part of the lifting rack, and the lower part of the lifting rack is respectively connected with a bottom rack by virtue of the oil cylinder I and the guide device I; and a fixator is hinged to both ends of the upper part of the fixed rack by virtue of pin shafts, the fixed rack is connected with the bottom rack by virtue of profile steel, a boss which protrudes to the inner side is arranged on the upper part of the fixator, and a groove which is matched with the boss of the fixator is formed in the outer side of the lower part of a casting mold. By adopting the demolding device and the demolding method, the aluminum ingot can be smoothly demolded, the service life of the casting mold is prolonged, and the casting mold is fixed by one oil cylinder, so that the operation is stable, the working efficiency is improved, and an occupied area is small.

Description

technical field [0001] The invention relates to the field of aluminum ingot casting, in particular to a demoulding device and a demoulding method for producing large aluminum ingots. Background technique [0002] In recent years, my country's electrolytic aluminum industry has developed very rapidly and has become the world's largest producer of primary aluminum. The 500kA large prebaked electrolytic cell has become the main cell type of my country's electrolytic aluminum industry, and the 600kA large prebaked electrolytic cell has been successfully developed. The matching molten aluminum casting production line is also required to meet the needs of large-scale production. Casting small aluminum ingots of about 20kg can no longer meet the production requirements, and the aluminum ingots lose about 0.4-0.5% during the casting process, that is, the consumption of primary aluminum by small aluminum ingots is higher than that of large aluminum ingots. Small aluminum ingots need ...
