The invention discloses a bimold drawing mold structure which comprises a front mold and a rear mold, wherein at least one guide wheel is arranged between the front mold and the rear mold; the guide wheel ensures that distribution of steel wires between the two molds changes, and the steels wires are not distributed on a straight line; on one hand, due to the existence of the guide wheel, the front and rear steel wires of each mold and the calibration bench of the mold are on a same straight line, so that the straightness of the steel wires during drawing can be ensured, i.e., the two molds are not required to have concentricity, so that the precision requirement for the two molds in use can be reduced; on the other hand, due to the existence of the guide wheel, the front mold and the rear mold preserve respective independence, when one mold is rotated so as to regulate the ring diameter of the steel wire, the ring diameter of the steel wires drawn by the other mold is not influenced, so that the ring diameter and pitch of the drawn steel wires can be regulated conveniently.
