PURPOSE:To replace forming molds easily in a short time, by replacing forming molds with plural mold carrying dollys and a ascending and descending means which allows these dollys to ascend and descend. CONSTITUTION:This replacing device consists of a carrying dolly 3 for a forming mold 5 provided with plural running wheels 7 and an ascending and descending means for ascent and descent of the dolly 3 which is used to set a lower face 4 of the dolly placed on a fixed base onto an upper face 2a of the fixed base 2 or separate this lower face 4 from the upper face 2a. This ascending and descending means is operated to raise the dolly 3, and this means is stopped when the upper face 2a of the fixed base 2 and the upper face of a supporting member 12 have the same height. Next, the dolly 3 where the forming mold 5 is set is carried to the outside. The second dolly 103 on a floor 13 is pressed in and is carried to the upper face of the supporting member, thus replacing the forming mold 5. |
