Plastic flowerpot forming device and method

The invention provides a plastic flowerpot forming device and a method thereof, and belongs to the technical field of plastic flowerpots, the plastic flowerpot forming device comprises a lower mold plate, an upper mold plate is arranged on the upper side of the lower mold plate, two electromagnets are connected in a spaced mode through the electromagnetic attraction effect between the two electromagnets, then a motor is started to enable an output shaft of the motor to rotate, and the lower mold plate is arranged on the lower mold plate. When injection molding is carried out, a driving disc, a plurality of telescopic rods, a follow-up disc, a threaded rod, a connecting rod, a third upper hopper and a third lower hopper are sequentially driven to rotate, then the third upper hopper and the third lower hopper gradually move upwards or downwards, deformation treatment is also carried out, and then injection molding liquid is injected into a lower mold plate through an injection molding opening.
