PURPOSE: A mold structure for forming a crease preventing projection on a panel is provided to adjust the projected height of a projected block member forming the crease preventing projection on the panel with a screw and to improve working efficiency and cut down cost without cutting and welding processes to lower and heighten the height of the projected block member. CONSTITUTION: A structure(100) for a mold(15) forming a crease preventing projection(13) for absorbing creases generated on a panel(11) in a flanging process of the panel having an elliptical side to the panel is composed of a projected block member(10), a semicircular block member(20), and a pressurizing member(30). The projected block member is installed to slide inward the mold and one side of the projected block member is protruded out of the mold and contacted with the panel to form the crease preventing projection. The semicircular block member is made into a semicircle shape to fit into a semicircular space unit formed in the mold, and contacted with the side of which the projected block member is inserted into the mold. The pressurizing member pressurizes the side of the semicircular block member, slides the semicircular block member along the semicircular space unit, pressurizes the lower side of the projected block member and moves the projected block member upward and downward.
