Vertical thermoplastic material injection molding machine and operation method thereof

The invention discloses a vertical thermoplastic material injection molding machine and an operation method thereof. The vertical thermoplastic material injection molding machine comprises a bottom plate, a base is fixedly connected to the top of the bottom plate, air cylinders are fixedly connected to the left side and the right side of the top of the base, and an injection molding machine body is fixedly connected to the inner sides of the air cylinders. According to the vertical thermoplastic material injection molding machine and the operation method thereof, mold bodies located at the top of a belt are conveyed through a first transmission wheel and a second transmission wheel, and after material injection of the mold bodies is completed, a transmission motor is started again and conveys the mold bodies to the front side of the base; and then mold bodies which are not subjected to injection molding are placed on the top of the belt again, and the mold bodies which are subjected to injection molding are d
