The electric valve 801 can be automatically opened and closed for automatic discharging. A fixing block 9 is provided at the bottom of the shell 2 by screw connection. A push rod 10 is slidably provided at the lower part of the fixing block 9. A material return rod 11 is slidably provided on the lower mold 5. The lower end of the material return rod 11 passes through the shell 2 and contacts and cooperates with the push rod 10. The side of the material return rod 11 in contact with the push rod 10 is an inclined surface. Under the action of the inclined surface, the push rod 10 moves backward to squeeze the material return rod 11 to move upward to eject the fast food box from the lower mold 5 to achieve demoulding. An elastic member 12 is sleeved on the lower end of the material return rod 11, and the two ends of the elastic member 12 are respectively connected to the material return rod 1 and the shell 2.

[0027] When in use, the first cylinder 3 is turned on, and the first cylinder 3 drives the upper mold 4 to move up and down. When the upper mold 4 is pressed down, the telescopic tube 8 extends, and the electric valve 801 is opened to open the liquid adding tube 7. The liquid plastic in the liquid storage tank 6 flows into the lower mold 5 along the liquid adding tube 7 and the telescopic tube 8. As the upper mold 4 is pressed into the lower mold 5, the electric valve 801 is closed, and the liquid plastic stops flowing out. The upper mold 4 and the lower mold 5 press the plastic into shape. After that, the upper mold 4 moves up and separates from the lower mold 5, and the telescopic tube 8 enters the liquid adding tube 7, and then pushes the push rod 10 backward, so that the push rod 10 squeezes the material return rod 11 to move up, and the material return rod 11 lifts the fast food box in the lower mold 5 to complete the demoulding.

[0028] Based on Example 1, please refer to Figure 4A storage box 13 is provided on the left side of the shell 2, and a release agent is contained in the storage box 13. The right side of the storage box 13 is connected and communicated with one end of a rubber tube 14, and the other end of the rubber tube 14 penetrates into the shell 2 and is installed with an airbag 15. The airbag 15 is connected and communicated with one end of a hose 16, and a nozzle 17 is installed at the other end of the hose 16. The hose 16 is a telescopic structure as a whole, which can be freely lengthened and shortened for convenient movement. A fixing rod 24 is fixedly connected to the shell 2, and a magnet 25 is provided on one end of the fixing rod 24 close to the nozzle 17. After the nozzle 17 is used, the magnetic force of the magnet 25 is used to fix and support the nozzle 17.

[0029] Before each round of lunch box production, the lower mold 5 needs to be sprayed with a release agent. The release agent in the storage box 13 can be drawn into the spray head 17 by pulling the spray head 17 to the right to the top of the lower mold 5 and then pressing the air bag 15. The release agent is then evenly sprayed into the lower mold 5 by the spray head 17, which can effectively prevent the mold and the fast food box from sticking together.
