the method comprises the following steps: an upper die (1) is arranged on the upper part of a lower die (2), and the upper die (1) and the lower die (2) are clamped with each other; when the whole die needs to be placed, adjusting rods (18) on the periphery of a base plate (7) are screwed, the adjusting rods (18) drive bevel gears (17) at the end parts to rotate, and the bevel gears (17) rotate on one sides of rack plates (23) to drive the rack plates (23) to move in the vertical direction; when the whole die needs to move, the supporting rod (22) extends out of the accommodating groove (20), and the supporting rod (22) moves downwards to drive the roller (19) at the bottom to protrude out of the accommodating groove (20); in the process that the supporting rod (22) moves up and down, the sliding grooves (21) on the two sides are clamped with the sliding rails (31), and the sliding rails (31) limit the moving direction of the supporting rod (22); after the four support rods (22) extend out, the four rollers (19) are contacted with the ground, and the rollers (19) support the whole mold at the bottom; the mould is pushed to move to the position where the mould needs to be placed; when the folding table is parked, the adjusting rod (18) is screwed to drive the supporting rod (22) to move upwards until the roller (19) at the bottom enters the containing groove (20), and the bottom of the base plate (7) is directly contacted with the ground;

step two: before the mold moves, protective mechanisms are arranged around the mold, so that the upper mold (1) and the lower mold (2) scatter after the mold is poured in the moving process; when the protection mechanism is installed, the inserting rods (28) at two ends of the protection rod (12) are respectively inserted into the inserting holes (3) in the upper die (1) and the edge plate (6), the threaded cylinder (27) is screwed to rotate, the threaded rod (30) moves in the threaded cylinder (27), the curvature of the protection rod (12) is further adjusted, and meanwhile, the protection rod (12) is adjusted to adapt to dies with different sizes;

step three: when the mould is normally used, the mould is arranged in the mould instrument; when the device is installed, the base plate (7) is fixed, then the lower die (2) is adjusted, and the upper die (1) is driven to adjust; when the lower die (2) is adjusted, the motor (4) drives the driving gear (10) at the bottom to rotate, and the driving gear (10) drives the driven gear (8) to rotate so as to drive the rotating shaft (9) to rotate; the rotating shaft (9) drives the lower die (2) and the upper die (1) on the upper part to rotate, and the orientation and the specific installation position of the die are adjusted;

step four: the base plate (7) can be installed or detached from the bottom of the lower die (2) during use; the fastening bolt (13) is unscrewed, the fastening bolt (13) is separated from the positioning hole (15), and the limiting block (14) can be separated from the inside of the insertion groove (16); when the base plate (7) needs to be used, the limiting blocks (14) are inserted into the insertion grooves (16), and the fastening bolts (13) are screwed down, so that the limiting blocks (14) can be fixed.
