The utility model provides a simple mechanical core-pulling device which comprises a first forming block and a second forming block which are arranged on a material pressing plate, a first guide block which is arranged on an upper die and drives the first forming block to move, and a second guide block which is arranged on a lower die and drives the second forming block, the first guide block drives the first forming block to move leftwards, and the second guide block drives the second forming block to move rightwards. And the second guide block drives the second forming block to move rightwards, so that the part controlled by the second forming block moves rightwards to be formed. The device is simple in structure, stable and effective in work, and capable of effectively achieving the purposes of conducting process machining on the negative angle of a part in a limited space and achieving forming of a cold punching inverted-U-shaped part. 本实用新型提供了一种简单机械抽芯装置，包括安装在压料板上的第一成型块、第二成型块、安装在上模上的、驱动第一成型块活动的第一导向块、安装在下模
