PROBLEM TO BE SOLVED: To rationalize motor-operated rotary vertical molding machine by making the employment of an electric motor as a driving source possible by securing a wide installation space in a machine base by omitting an elevator in the middle of a rotary board by supporting the rotary board always by supporters embedded in a base. SOLUTION: A half part of a plane in a molding part A, the other half as an ejection part B, the upper part of the machine base 1, and the base 2 is installed. The rotary board 3 is mounted freely rotatably on the base 2. The motor which rotates the rotary board 3 by gears is installed in the machine base of the ejection part B. A mold clamping device 4 is installed in the machine base of the molding part A. The lower ends of towing shafts 8 formed freely vertically movably on the base 2 are connected to the mold clamping device 4, and a movable board 9 which is supported horizontally at an upper end is installed freely vertically movably. Molds 10a, 10b are installed in the movable board 9 and the rotary board 3. A projection device 5 with a driving source made an electric motor is installed in the machine base of the ejection part 4. The rotary board 3 is mounted freely rotatably on the base with the lower surface contacted always with the supporters 24 embedded in the upper surface of the base board of the molding part A. The supporters 24 are made of a composite material comprising a bearing alloy or a synthetic fiber cloth and a thermosetting resin, etc.
