The inner wall of the lower side of the box 7 is welded, and the baffle 10 is symmetrically welded and fixed on the adjusting rod 9. The baffle 10 is in contact with the inner wall of the cooling box 1 connected with the ventilation pipe 8. When the adjusting rod 9 moves up and down, the baffle 10 can The through groove 10 is closed, so that the high-temperature steam in the cooling box 1 cannot flow into the upper part of the air pressure box 7 from the through groove 11, so that the adjusting rod 9 cannot move upward.

The opening mechanism includes a T-shaped rod 15 passing through the water hole 14. The lower end of the T-shaped rod 15 is welded and fixed with a clamping plate 17, and the clamping plate 17 is in contact with the lower side of the partition plate 2. One end is welded and fixed with a second spring 16, the second spring 16 is welded with the upper side of the partition plate 2, the lower end of the water passage 14 is welded and fixed with a communication pipe 18, and the lower end of the communication pipe 18 is welded and fixed and communicated with an annular cylinder 19. 19 A plurality of water mist holes are provided through the side wall.

The cross-sectional radius of the clamping plate 17 is larger than the cross-sectional radius of the water passage hole 14 , the cross-sectional radius of the clamping plate 17 is smaller than the cross-sectional radius of the communication pipe 18 , and the cross-sectional area of the upper end of the T-shaped rod 15 is smaller than that of the water passage hole 14 . , so that the water passage hole 14 cannot be blocked. When the clamping plate 17 is in contact with the lower side of the dividing plate 2, the water flow cannot flow into the communication pipe 18 from the water passage hole 14. When the clamping plate 17 is out of contact with the lower side of the dividing plate 2 , the water flow can flow into the communication pipe 18 from the water passage hole 14 .

One side of the cooling box 1 is provided with a concave hole, and the opposite side of the cooling box is provided with a corresponding groove, the filter plate 4 is inserted into the groove through the concave hole, and the filter plate 4 is sealed and slidably connected with the groove to prevent the inside of the cooling box 1. The water flow overflows from the connection between the filter plate 4 and the side wall, and when the filter plate 4 needs to be cleaned, the filter plate 4 is taken out.

The ventilation pipe 8 communicates with the cooling box 1 and the chute 6 between the filter plate 4 and the partition plate 2. The ventilation pipe 8 communicates with the air pressure box 7 at the lower end of the adjustment rod 9, and the high temperature steam flows through the ventilation pipe 8 to the air pressure box. 7. Push the adjusting rod 9 upward, the air in the air box 7 above the adjusting rod 9 flows out from the through hole 12, and the adjusting rod 9 moves upwards under the push of high temperature steam, thereby adjusting the water outlet mode of the annular cylinder 19.

In the initial state of the device of the present invention, the adjusting block 20 on the adjusting rod 9 is located at the entire bottom of the annular cylinder 19 and is not in contact with the annular cylinder 19. Open the box door and place the mold on the filter plate 4, close the box door, and open the water pump to the storage tank. The water in the water chamber 3 is supplied with water, and the water in the water storage chamber 3 is subjected to the pressure given by the pressure pump, and the water pushes the T-shaped rod 15 downward to make the clamping plate 17 move downward. The cross-sectional area is large, so that the water passage hole 14 cannot be blocked, and the second spring 16 is compressed, so that the water storage chamber 3 and the communication pipe 18 are connected through the water passage hole 14, and the water flow flows from the communication pipe 18 to the annular cylinder 19. At this time, the annular The cylinder 19 is in the downward spraying state of the water column, and the water flow cools the mold. Since the surface temperature of the mold is too high, the water adheres to the surface of the mold and absorbs heat and evaporates to take away heat. The surface of the mold begins to cool down, and the high-temperature steam flows through the ventilation pipe 8 to the air pressure The adjusting rod 9 is pushed upward in the box 7, the air above the adjusting rod 9 of the air pressure box 7 flows out from the through hole 12, the adjusting rod 9 moves upwards under the push of the high temperature steam, and when the adjusting rod 9 moves up and down, the baffle 10 can The through groove 10 is closed, so that the high temperature steam in the cooling box 1 cannot flow into the upper part of the air pressure box 7 from the through groove 11, so that the adjusting rod 9 cannot move up and down.

The adjustment rod 9 drives the adjustment block 20 to move upward, and the adjustment block 20 starts to move into the annular cylinder 19. After the adjustment block 20 enters the annular cylinder 19, a part of the outlet at the lower end of the annular cylinder 19 is blocked, so that the pressure in the annular cylinder 19 increases, resulting in The water mist hole on the side wall of the annular cylinder 19 begins to emit water, and the water is converted into water mist and scatters outward. At this time, the water outlet of the annular cylinder 19 is a part of the water column plus a part of the water mist, and the adjustment block 20 completely enters the annular cylinder 19. , the outlet at the lower end of the annular tube 19 is completely blocked, so that the pressure in the annular tube 19 increases, causing all the water mist holes on the side wall of the annular tube 19 to start to flow out water and the lower end of the annular tube 19 no longer emits water, and all the water is converted into water mist to the When the water is sprayed out, the water outlet of the annular cylinder 19 is in the state of completely spraying water mist.

At this time, the surface temperature of the mold is low, and no steam is generated in the cooling box. The water mist can cool the mold well. The water flowing out from the annular cylinder 19 enters the water storage cavity after being filtered by the filter plate 4. 5, after the cooling work is completed, the water pump is stopped, and the clamping plate 17 is in contact with the lower side of the partition plate 2 under the elastic force of the second spring 16, so that the water flow stops flowing out, the high-temperature steam is cooled, and the adjusting rod 9 is in the first spring 13. Under the action, it returns to the initial position, and the valve is opened so that the liquid in the water storage chamber 5 flows out.

The above description is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited to this. Equivalent replacement or modification of the new technical solution and its utility model concept shall be included within the protection scope of the present utility model.
