Aluminum ingot demolding device

The invention relates to the technical field of metal casting, in particular to an aluminum ingot demolding device which comprises a rack, a working table is arranged on the upper surface of the rack, a mold cavity is formed in the working table, a demolding mechanism is arranged in the portion, below the mold cavity, of the rack, and the demolding mechanism comprises a plurality of ejector rod assemblies and control rod assemblies which are transversely arranged at intervals. The bottoms of the ejector rod assemblies and the bottoms of the control rod assemblies are connected through driving parts to control the up-down movement direction, due to the matched arrangement of the ejector rod assemblies, the control rod assemblies, the L-shaped plates and the control plates, the action synchronism of the ejector rod assemblies in all rows can be improved, it is guaranteed that the impact force of all the positions of the bottom face of the die cavity is consistent, and the die quality is improved. And the proble
