Stamping mold for dual-phase steel forming springback control

The invention discloses a stamping mold for dual-phase steel forming springback control in the technical field of stamping, comprising a stamping base, a lower template, a lower mold holder, a mold cavity, a guide column, an upper mold holder, a punch, a lug block and a sliding groove; a circulation cavity is formed in the lower mold holder; a pipe joint is arranged on the outer wall of the lower mold holder; two pipe joints respectively communicate with a liquid inlet and a liquid outlet of external heat-conducting oil conveying equipment; and a plurality of bulges are arranged on the part, corresponding to the mold cavity, of the top of the lower template. By means of a concave part defined by every two adjacent bulges, when dual-phase steel is stamped, the acting force borne by a stamping surface of the dual-phase steel can be counteracted through deformation of a non-stamping surface towards the interior of the concave part, and therefore the springback amplitude of the dual-phase steel can be reduced; an
