The driven roller 26 is dynamically connected, and the two ends of the driven roller 26 are symmetrically connected to the second bracket 27. When the metal casting moves to the driven roller 26, the motor 23 is started, so that the active roller 24 connected to it through the coupling will rotate forward, and then the active roller 24 will rotate forward together with the driven roller 26 through the conveyor belt 25. Then the metal casting will move forward along the driven roller 26 through friction. At this time, the water pump box 201 is started again, so that the coolant in the water reservoir 21 will enter its interior and pass into the four-connected pipe 20 from its outlet. The top of the four-connected pipe 20 is connected to four sprayers 29, so the top of the sprayer 29 will spray coolant, thereby playing a role in cooling the inside and outside of the metal casting at the same time.

When the metal casting moves along the fixed rail 141 to the lower position of the door panel frame 13, the air pump 36 is started, and the air intake pipe 35 of the air pump 36 will generate suction, and the other end of the air intake pipe 35 is connected to the first double-headed pipe 31, and the other end of the first double-headed pipe 31 is connected to the suction head 33, so the suction head 33 will absorb the heat emitted from the metal casting, thereby pre-cooling it. , and prevent the high-temperature air flow from carrying out the debris on the metal casting and adhering to the skin or equipment. The heat will be discharged from the outlet pipe 38 of the air pump 36 and enter the exhaust pipe 39. Then, the hot air flow filtered by the No. 1 filter 30 will hit the heat conductive plate 303. At this time, the heat conductive plate 303 will absorb the heat in the hot air flow, and the cooled gas will be discharged outward through the inclined panel 302 and the air outlet 301 in turn, thereby cooling the hot air flow and avoiding air pollution.

[0052] A through hole 306 is provided at the portion where the control box 34 is connected to the water reservoir 21, and a second filter screen 307 is fixedly connected inside the through hole 306. A blocking plate 308 is slidably adapted on one side of the control box 34 near the second filter screen 307. The blocking plate 308 is inserted into the bottom of the control box 34, and a floating plate 309 is fixedly connected to the outside of the blocking plate 308. The floating plate 309 is slidably adapted inside the control box 34, and a spring 300 is fixedly connected to the bottom of the floating plate 309. The bottom end of the spring 300 is fixedly connected to the At the bottom of the inner cavity of the control box 34, a small water pump 304 is arranged above the floating plate 309. The small water pump 304 is fixedly connected to the bottom of the partition 37. The outer side of the small water pump 304 is fixedly connected to a suction pipe 305.

The bottom of the control box 34 is formed by the floating plate 309 and the blocking plate 308. As the coolant in the control box 34 rises, the floating plate 309 and the blocking plate 308 move upward until the blocking plate 308 blocks the No. 2 filter screen 307.

Then the large Part of the coolant will flow downward from the square hole 17 on the traction plate 16 and sprinkle on the metal casting through the outflow hole 19. Another small part of the coolant will flow downward from both sides of the inner cavity of the door panel frame 13 and flow downward from the reflux hole 18, and finally return to the water reservoir 21 along the guide plate 12, thereby pre-cooling the metal casting to prevent it from being directly poured with coolant, resulting in too fast cooling speed, inconsistent shrinkage speed of different parts of the casting, and generating greater thermal stress.

The top of the four-connected pipe 20 is connected to four sprayers 29, so the top of the sprayer 29 will spray coolant, thereby realizing simultaneous cooling and temperature reduction treatment of the inside and outside of the metal casting.

[0055] When the metal casting moves along the fixed rail 141 to the position of the door panel frame 13, the air pump 36 is started, and the air inlet pipe 35 of the air pump 36 will generate suction, and the other end of the air inlet pipe 35 is connected to the No. 1 double-headed pipe 31, and the other end of the No. 1 double-headed pipe 31 is connected to the suction head 33, so the air pump 36 will absorb the heat emitted from the metal casting, and the heat will be discharged from the air outlet pipe 38 of the air pump 36 and enter the exhaust pipe 39, and then the hot air flow filtered by the No. 1 filter 30 will hit the heat conducting plate 303, and the heat conducting plate 303 will absorb the heat in the hot air flow, and the cooled gas will be discharged outward through the inclined panel 302 and the air outlet 301 in turn. In addition, when the metal casting moves along the fixed rail 141 to the position of the door panel frame 13, part of the coolant in the water reservoir 21 will enter the bottom of the inner cavity of the control box 34 through the through hole 306 and the second filter screen 307 in turn, and as the coolant in the control box 34 rises, the floating plate 309 and the blocking plate 308 will move upward until the blocking plate 308 blocks the second filter screen 307. At this time, the small water pump 304 is started again, so that the water suction pipe 305 will pump the coolant in the control box 34 into the bottom of the inner cavity. The coolant is absorbed and discharged from the No. 2 double-ended pipe 32, and the other end of the No. 2 double-ended pipe 32 is connected to the top of the door panel frame 13, so the coolant will pass through the top hole 15 and flow on the traction plate 16, and then most of the coolant will flow downward from the square holes 17 on the traction plate 16, and sprinkle on the metal casting through the outflow hole 19, and a small amount of coolant will flow downward from both sides of the inner cavity of the door panel frame 13, and flow downward from the reflux hole 18, and finally return to the water reservoir 21 along the guide plate 12.
