A bending mold capable of thermally bending an automotive windscreen comprises a fixed frame and two movable frames. A curvature adjusting apparatus is additionally provided corresponding to the bottom of each movable frame. Each curvature adjusting apparatus comprises two sidings, two hooks and an adjusting lever. The adjusting lever is in parallel to the connection line of two hinge connection points of the movable frame and the fixed frame on the same side, and the tops of the two hooks are respectively hanged on two corresponding sidings at adjustable positions. The process of thermally bending automotive glass can be accomplished with the bending mold, and does not require installing an anti-gravity mechanism. It has the advantages of simple mold structure design, less amount of materials and so on.
