[0042] The lower side of the tank body 1 is provided with a mounting plate 6, and a mounting groove 7 is provided on the upper side of the mounting plate 6. A bidirectional screw 8 is rotatably engaged with the inner wall of the mounting groove 7. Two sliding seats 24 are threadedly engaged on the bidirectional screw 8. A lifting plate 9 is provided on the mounting groove 7. Two connecting rods 10 are provided between the lifting plate 9 and the sliding seat 24. A motor 11 is installed on one side of the mounting plate 6. A sealing disk 12 is installed on the upper side of the lifting plate 9. An air intake groove 13 that cooperates with the sealing disk 12 is provided on the lower side of the tank body 1. The two ends of the connecting rod 10 are respectively rotatably engaged with the lifting plate 9 and the sliding seat 24. The output end of the motor 11 is fixedly connected to one end of the bidirectional screw 8, and the sliding seat 24 is slidably engaged with the inner wall of the mounting groove 7.

[0043] Implementation process: Under the action of the motor 11, the bidirectional screw rod 8 rotates, and the rotation of the bidirectional screw rod 8 drives the two sliding seats 24 to move outward. Under the transmission of the connecting rod 10, the lifting plate 9 moves upward, so that the blocking disk 12 cooperates with the air inlet groove 13 to seal the tank body 1, which is convenient for vacuuming the inside of the tank body 1. When it is necessary to cool the heating furnace 2, the motor 11 is reversed to make the bidirectional screw rod 8 drive the two sliding seats 24 to move inward. Under the transmission of the connecting rod 10, the blocking disk 12 is separated from the air inlet groove 13, and the seal of the air inlet groove 13 is cancelled.

[0044] Implementation benefits: It is easy to seal and open the air inlet groove 13, and the sealing effect is good, the separation is convenient, and the convenience of using the equipment is improved.

[0045] Example 2

[0046] A mounting bracket 14 is fixedly connected to the lower side of the inner wall of the tank body 1, and a fan 15 is installed on the mounting bracket 14, and the fan 15 cooperates with the air inlet groove 13.

The lower side of the heating furnace 2 is provided with multiple air inlets 17, and the upper side of the heating furnace 2 is provided with an air outlet 18.

[0047] Implementation process: When it is necessary to cool the mold body 4 inside the heating furnace 2, the sealing disk 12 is separated from the air inlet groove 13 under the action of the motor 11, and then the outside air is transported into the tank body 1 through the air inlet groove 13 under the action of the fan 15, and then transported into the heating furnace 2 through the air inlet 17. As the air circulates, the fan blades 16 are driven to rotate to disperse the air.

[0048] Implementation benefits: The fan blades 16 rotate to make the air flow even, thereby improving the cooling effect on the mold body 4.
