The utility model relates to the field of extrusion dies, and discloses a high-efficiency hard aluminum core extrusion die which comprises two bases, the top ends of the two bases are fixedly connected with a lower transverse plate, the middle of the top end of the lower transverse plate is fixedly connected with a lower die, and the left side of the top end of the transverse plate is fixedly connected with a motor. The motor drives the threaded rod to rotate, meanwhile, the threaded sleeve spirally connected to the outer portion of the threaded rod moves rightwards, the shell on the connecting rod is driven to move rightwards and slowly get close to the upper portion of the lower die, and the brush below the shell is attached to the surface of the lower die. And residual aluminum on the surface of the lower die can be cleaned. A plurality of springs are arranged above the brush, when the brush reaches the concave position of the lower die, the internal springs drive the T-shaped pushing plate to move downwar
