[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention moves the first force-bearing block through the extrusion plate, thereby driving the connecting rod to move downward. As the connecting rod moves downward, the lower pressure plate can be driven to move downward. The downward movement of the lower pressure plate can generate a downward extrusion force on the filter plates on both sides. At this time, the filter plates rotate downward through the first rotating shaft, so that the filter plates on both sides can be opened, so that the impurities and scale accumulated thereon can roll downward for subsequent centralized collection and treatment. In this way, the impurities and scale in the cooling water can be filtered and the scale impurities can be centrally treated, thereby preventing the cooling trough and the filter plate from being blocked by the scale, thereby ensuring the normal operation of the subsequent cooling work.

[0022] According to the present invention, the upper mold moves upward to drive the second force-bearing block to move upward. At this time, the second force-bearing block is squeezed by the squeezing rod and moves inward, driving the sliding column to move during the movement, and squeezing the second spring at the same time. The second force-bearing block drives the sealing plate to move synchronously. When the sealing plate moves to the lower end of the sealing frame, the cooling groove opened in the upper mold can be sealed. This can prevent the cooling water in the cooling groove from leaking and dripping onto the valve body during the upward movement of the upper mold, thereby affecting the casting of the valve body.

[0023] The present invention drives the second bevel gear to rotate by rotating the first bevel gear, thereby driving the turntable and the shifting rod to rotate. At this time, the shifting rod will squeeze the rotating rod so that the rotating rod rotates upward through the rotation of the second rotating shaft, and at the same time drive the striking block to rotate downward. As the second rotating shaft rotates, the torsion spring is synchronously driven to rotate. When the shifting rod is away from the rotating rod, the torsion spring performs reset rotation and then drives the striking block to reset and strike the bottom end of the filter plate, thereby striking and vibrating the filter plate, so that the impurities and scale accumulated thereon can be vibrated to loosen them, thereby improving the flow guidance of the impurities and scale, ensuring that the impurities and scale can roll downward as the filter plate is tilted and opened, thereby preventing the impurities and scale remaining thereon from clogging the filter plate and ensuring the subsequent filtering effect.

[0024] The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Embodiment 3:

[0047] The difference between the above embodiment and this embodiment is that: Figures 1 to 9 As shown, a ball valve body casting process, the filtering vibration mechanism 33 includes a first bevel gear 331, the first bevel gear 331 is meshed with a second bevel gear 332, the outer wall of one end of the second bevel gear 332 is connected to a connecting shaft 334, the outer wall of the connecting shaft 334 is rotatably provided with a limiting sleeve 333, one end of the limiting sleeve 333 is connected to the outer wall of the filter box 3110, the connecting shaft 334 is connected to a turntable 335 at one end away from the second bevel gear 332, the outer wall of the turntable 335 is provided with a movable hole, the inner wall of the movable hole is connected to a third spring 3312, and the end of the third spring 3312 away from the inner wall of the movable hole is connected to a lever 3313.

[0048] Furthermore, the outer wall of the filter box 3110 is connected to a fixed block 336, and a rotating groove is provided on the outer wall of the fixed block 336. The inner wall of the rotating groove is connected to a torsion spring 337, and the end of the torsion spring 337 away from the inner wall of the rotating groove is connected to the second rotating shaft 338, and the outer wall of the second rotating shaft 338 is connected to a rotating rod 339, and the outer wall of one end of the rotating rod 339 is connected to a knocking block 3310. A through groove is provided on the outer wall of the filter box 3110, and the outer wall of the rotating rod 339 is movably arranged on the inner wall of the through groove, and the outer wall of the rotating rod 339 is connected to a sealing cloth 3311, and the sealing cloth 3311 is connected to the inner wall of the through groove away from the rotating rod 339. There are several levers 3313, and the levers 3313 are evenly and equidistantly distributed on the outer wall of the turntable 335, and the end away from the third spring 3312 is set in an arc shape.

[0049] Furthermore, the sealing cloth 3311 is made of a flexible material and is distributed on the inner wall of the through groove in a folded and wavy state, so that a distance space for pulling up and down can be provided during the rotation of the lever 3313, and the through groove can be sealed at the same time.

[0050] The implementation principle of a ball valve body casting process of this embodiment is as follows: after the casting is completed, the water pump 3121 is started, so that the cooling water in the water tank 3120 can be transmitted to the cooling groove 313 opened in the lower mold 3123 and the upper mold 311 through the second connecting pipe 3122, so that the cooling water flows and circulates in the cooling groove 313 between the two, and then passes through the filter box 3110 and recirculates to the water tank 3120 to repeatedly achieve the cooling effect. The cooling water in the filter box 3110 will be filtered through the filter plate 3112, so that the scale generated by the cooling water due to cooling and heating can be filtered to prevent long The cooling cycle of the time adheres to the cooling groove 313 or the water tank 3120. After cooling is completed, as the upper mold 311 moves upward, the sealing plate 327 will seal the cooling groove 313 of the upper mold 311, so that the sealing plate 327 can drive the extrusion plate 314 to move, and the extrusion plate 314 will squeeze the first force block 315, and then the first force block 315 will move downward. As the first force block 315 moves downward, the connecting rod 316 can be driven to move downward, and at the same time, the connecting rod 316 drives the supporting connecting plate 3124 to move downward, and then the supporting connecting plate 3124 squeezes and compresses the first spring 3125, and at the same time The connecting rod 316 drives the lower pressure plate 3113 to move downward, and the lower pressure plate 3113 that moves downward will squeeze the filter plates 3112 on both sides. At this time, the filter plates 3112 on both sides will rotate downward through the rotation of the first rotating shaft 3111. During the rotation of the filter plates 3112, the first hinge seat 3116, the linkage rod 3117 and the second hinge seat 3118 can be driven to rotate. In this way, the filter plates 3112 on both sides can be in a downwardly inclined state, so that the filtered accumulated impurities can be guided downward to roll due to the action of gravity, so that the impurities are accumulated on the inner wall base of the filter box 3110, and finally the working Personnel can concentrate on collecting and processing. Later, as the upper mold 311 is reset for casting, the sealing plate 327 is reset to drive the extrusion plate 314 to no longer contact the first force block 315, and the first spring 3125 can be reset to drive the connecting rod 316 to move up and reset. Then the connecting rod 316 drives the lower pressure plate 3113 to move up, thereby pulling the filter plates 3112 on both sides to reset and rotate, and complete the closure. In this way, impurities and scale in the cooling water can be filtered while the scale impurities can be centrally processed, thereby preventing scale from causing blockage of the cooling trough 313 and the filter plate 3112, thereby ensuring the normal operation of subsequent cooling work.

[0051] As the upper mold 311 moves upward, the second force-bearing block 326 will be driven to move upward. As the second force-bearing block 326 moves upward, it will contact and be squeezed by the squeezing rod 322. The squeezed second force-bearing block 326 will drive the connecting plate 325 to move inward. As the connecting plate 325 moves, the sliding column 324 can be driven to move. At this time, the sliding column 324 can squeeze the second spring 323. The synchronous connecting plate 325 will drive the sealing plate 327 to move inward, so that the sealing plate 327 can move to the bottom end of the sealing frame 329. The second spring 323 is used to seal the sealing plate 327, thereby sealing the cooling groove 313 of the upper mold 311. This can prevent the cooling water in the cooling groove 313 from leaking and dripping onto the valve body during the upward movement of the upper mold 311, thereby affecting the casting of the valve body. As the upper mold 311 moves downward, the second force block 326 will gradually lose the extrusion of the extrusion rod 322, and then the sealing plate 327 can be reset by the rebound of the second spring 323, thereby reopening the cooling groove 313 opened on the upper mold 311.

[0052] As the filter plate 3112 rotates downward, the first rotating shaft 3111 will drive the first bevel gear 331 to rotate, thereby driving the second bevel gear 332 meshing therewith to rotate, and the rotation of the second bevel gear 332 can drive the connecting shaft 334 and the rotating disk 335 to rotate counterclockwise, and as the rotating disk 335 rotates, the lever 3313 on its outer wall can be driven to rotate, and as the lever 3313 rotates, it can contact and squeeze the rotating rod 339, and the squeezed rotating rod 339 will drive the second rotating shaft 338 to rotate, and at the same time, the second rotating shaft 338 drives the torsion spring 337 to rotate, and as the rotating rod 339 rotates, the knocking block 3310 on one side will be driven to move downward, and as the rotating disk 335 continues to rotate, the lever 3313 continues to rotate, and then The lever 3313 will be squeezed by the rotating rod 339 and slide inward, while squeezing the third spring 3312. At this time, the lever 3313 will release the contact and squeezing on the rotating rod 339, so that the torsion spring 337 can be reset to drive the second rotating shaft 338 and the knocking block 3310 to reset and rotate upward. At this time, the top end of the knocking block 3310 can knock on the bottom end of the filter plate 3112, thereby vibrating the filter plate 3112, so that the impurities and scale accumulated thereon can be vibrated and loosened, thereby improving the flow guidance of the impurities and scale, ensuring that the impurities and scale can roll downward as the filter plate 3112 is tilted and opened, thereby preventing the impurities and scale remaining thereon from clogging the filter plate 3112 and ensuring the subsequent filtering effect.
