[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 4 One embodiment of the present invention is: a cooling device for a continuous casting mold, comprising: a graphite mold 1, a connecting ring 2 is fixedly installed on the surface of the graphite mold 1, and a water inlet 3 is fixedly installed at the bottom of the connecting ring 2; a cooling device, the cooling device comprises a connecting pipe 4, a circular pipe 5, a nozzle 6, a sealing block 7, a driving device 8, a hollow ring 9, a sealing slide plate 10, a connecting rod 11 and an arc plate 12, to prevent uneven cooling from causing different shrinkage speeds of different parts of the forging during the cooling process, thereby causing size changes and shape deformation, the connecting pipe 4 is fixedly installed at the water inlet 3 surface, the circular tube 5 is fixedly mounted on the circumferential surface of the connecting tube 4, the nozzle 6 is fixedly mounted on the circumferential surface of the circular tube 5, the sealing block 7 is fixedly mounted on the inner wall of the water inlet 3, the driving device 8 is fixedly mounted on the inner wall of the water inlet 3, the hollow ring 9 is fixedly mounted on the output end of the driving device 8, the sealing slide plate 10 is slidably mounted on the inner wall of the water inlet 3, the connecting rod 11 is fixedly mounted on the bottom of the sealing slide plate 10, and the arc plate 12 is fixedly mounted on the bottom of the connecting rod 11 to prevent excessive cooling water from being sprayed out, resulting in rapid cooling and thermal stress on the surface of the casting, thereby increasing the wear and damage risk of the casting.

[0030] The hollow ring 9 is arranged below the sealing block 7, and the sealing effect is achieved by overlapping the hollow ring 9 and the sealing block 7. The connecting tube 4 and the circular tube 5 are both arranged on the inner wall of the graphite mold 1. A No. 1 spring is arranged between the sealing slide plate 10 and the water inlet 3. The No. 1 spring drives the sealing slide plate 10 to reset, and the arc plate 12 contacts the inner wall of the water inlet 3.

[0031] When the embodiment is working, cooling water enters the connecting pipe 4 through the water inlet 3, and then enters the circular pipe 5 through the connecting pipe 4. The cooling water is then sprayed out through the nozzle 6 to evenly cool the forged part in the graphite mold 1, so as to prevent uneven cooling from causing different shrinkage speeds of different parts of the forged part during the cooling process, thereby causing size changes and shape deformation. At the same time, the driving device 8 moves downward to drive the hollow ring 9 to move up and down. When the hollow ring 9 moves upward, it will overlap with the sealing block 7, and the water inlet 3 will be sealed by the overlap, so as to control the amount of cooling water entering. Controlling the cooling spray volume can ensure that the cooling medium covers the entire mold surface at an appropriate rate and amount, thereby improving the overall cooling effect. At the same time, when the cooling water flow rate is too fast, it will push the sealing slide 10 to move upward. The upward movement of the sealing slide 10 will drive the connecting rod 11 and the arc plate 12 to move upward. The upward movement of the arc plate 12 will block the water inlet hole of the connecting pipe 4, thereby reducing the amount of water entering the connecting pipe 4 and reducing the speed, thereby preventing excessive cooling water from being sprayed out, resulting in rapid cooling and thermal stress on the surface of the casting, thereby increasing the wear and damage risk of the casting.

[0034] A torsion spring No. 1 is arranged between the connecting frame 134 and the tooth block 135 , which drives the tooth block 135 to reset. The surface of the limit block 136 contacts the surface of the tooth block 135 , so that the tooth block 135 can only rotate in one direction, and the scraper 1312 contacts the surface of the filter plate 133 .

[0035] A scraping device is provided at the bottom of the filtering device, and the scraping device includes an L-shaped rod 141, a guide frame 142, a rotating plate 143, a recovery box 147 and a water outlet 148.

The scraper 1312 pushes the impurities back, affecting the collection of the recovery box 147.

[0036] A protrusion 144 is fixedly installed on the surface of the guide frame 142, a fixing plate 145 is fixedly installed on the top of the L-shaped rod 141, and a spring 146 is fixedly installed on the surface of the fixing plate 145 to prevent impurities from adhering to the scraper 1312 and falling back onto the filter plate 133 during the resetting process of the scraper 1312, thereby affecting the filtering effect of the filter plate 133 and the scraping effect of the scraper 1312.

[0037] A second torsion spring is provided between the rotating plate 143 and the guide frame 142 , and the rotating plate 143 is driven to return to its original position by the second torsion spring. One end of the guide frame 142 close to the recovery box 147 is provided as an inclined surface.

[0038] The cooling water is led into the recovery pipe 132 through the guide groove 131, and the impurities in the water are filtered by the filter plate 133 to prevent the impurities from being in the cooling water and affecting the recycling. At the same time, when the hollow ring 9 reciprocates up and down, it will drive the connecting frame 134 to reciprocate up and down, and the downward reciprocating movement of the connecting frame 134 will drive the gear block 135 to move downward. When the gear block 135 moves upward, the left gear block 135 will be limited by the limit block 136, and the gear 137 will rotate downward under the reverse force. During the downward rotation of the gear 137, it will contact the right gear block 135, and the gear 137 will push the gear block 135 to rotate in the direction away from the gear 137, without affecting the gear 137. The rotation of gear 137 forms an obstacle. At the same time, when the connecting frame 134 drives the tooth block 135 to move downward, the relationship between the two will be reversed. Through the arrangement of the tooth block 135 and the limit block 136, the gear 137 will only rotate in one direction during the up and down reciprocating motion of the tooth block 135.

[0039] At the same time, the reciprocating motion of the scraper 1312 will drive the L-shaped rod 141 to reciprocate, and the L-shaped rod 141 will move along the slide groove of the guide frame 142. When the L-shaped rod 141 moves in the direction close to the recovery box 147, it will contact the inclined surface of the guide frame 142, and the L-shaped rod 141 will move upward along the inclined surface of the guide frame 142. During the upward movement of the L-shaped rod 141, it will contact the rotating plate 143, and the L-shaped rod 141 will push the rotating plate 143 to rotate upward. When the L-shaped rod 141 is separated from the rotating plate 143, the No. 2 torsion spring will drive the rotating plate 143 to reset. The resetting of the rotating plate 143 will block the L-shaped rod 141 to prevent the L-shaped rod 141 from moving downward. The upward movement of the L-shaped rod 141 will The scraper 1312 is driven to move upward, and the scraper 1312 is separated from the filter plate 133 to prevent impurities from remaining on the filter plate 133 during the resetting process of the scraper 1312.
