[0032] The working principle of the present utility model: In use, after the shoe lasts are sent out from the outlets of multiple injection molding machines, they are conveyed by the corresponding first feeding conveyor or the second feeding conveyor of each injection molding machine, and are sent into the right part of the water tank through the first conveyor belt and the second conveyor belt. The continuous entry of the shoe lasts will press down the previous shoe last. The shoe lasts pass through the sinking baffle and enter below the guiding conveyor. Due to the buoyancy of water, they will move upward to abut against the conveyor belt of the guiding conveyor, and are slowly moved leftward in the water tank under the pressure of the conveyor belt of the guiding conveyor to cool the injection-molded shoe lasts. The shoe lasts conveyed by the first feeding conveyor are conveyed by the first guiding conveyor belt, and the shoe lasts conveyed by the second feeding conveyor are conveyed by the second guiding conveyor belt. When conveyed to the feeding conveyor, the scraping plates arranged on the conveyor belt of the feeding conveyor can pick up the shoe lasts and convey them to the upper left. The scraping teeth arranged on the scraping plates can ensure better picking up of the shoe lasts. The shoe lasts fall onto the conveyor belt of the discharging conveyor under the conveyance of the feeding conveyor, and then are sent into the heat preservation box for heat preservation, and are left to cool slowly naturally in the heat preservation box for 3 days to prevent different internal and external cooling speeds, thermal expansion and contraction, and generation of air bubbles; Through the setting of the double feeding conveyor in cooperation with the double guiding conveyor belts, the overall efficiency can be improved.
