In a method of mounting and demounting at least two, upper and lower dies to and from a press molding machine, a workpiece is inserted into a press position between the upper and lower dies. The workpiece is then pressed or stamped at the press position by the upper and lower dies. The upper and lower dies are maintained at the press position to leave the workpiece after having been pressed or stamped, at the press position between the upper and lower dies. The upper and lower dies are mounted and demounted to and from the press molding machine, with the workpiece maintained at the press position between the upper and lower dies.
