The present invention relates to the technical field of dies. Provided is a die core-pulling mechanism. The problem of an existing die failing to perform blanking on irregular parts is solved. A die comprises an upper die and a lower die. The core-pulling mechanism comprises: a swinging block, which is hinged in the lower die; and a sliding block, which is movably arranged in the lower die, wherein the swinging block is located on the sliding block and abuts against the sliding block, and the top of the swinging block has a cavity wall; an irregular cavity is recessed in the cavity wall, and the bottom of the swinging block has a first guide surface and a first abutting surface; the top of the sliding block has a second abutting surface and a second guide surface; and when the sliding block moves to cause the first guide surface and the second guide surface to be fitted with each other and relatively move, the swinging block swings about a hinged joint, and when the first abutting surface and the second abutt
