<p>The present invention relates to a mold for manufacturing a door frame. More specifically, the present invention is invented to reduce processing costs and working processes, work various shapes, manufacture a precise product, and more easily manufacture a product. To achieve the objective, the mold, according to the present invention, is manufactured such that only one mold (up, down) located on the upper side thereof is maintained as a polygon and the remaining mold is maintained at a right angle, thereby producing various shapes of door frames, reducing abrasion despite excessive use, and thus maintaining preciseness. In addition, the present invention can simplify the shape of the mold to eliminate a removal device of the door frame, reduce manufacturing costs for the mold, and raise productivity by expanding a processing range through the change of the mold shape and decreasing the number of molds and working processes.</p> |
