DETAILED DESCRIPTION

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0039] Example 1: Please refer to Figures 1-9, when cooling the casting mold, the existing heat dissipation structure cools the casting mold by combining spraying and air cooling. However, when spraying the mold, its own spray range is fixed, and only a fixed area of ​​the mold can be sprayed for cooling. If there is a spray blind area when cooling the mold, it is easy to cause uneven cooling of various parts of the mold, thereby reducing the molding effect of the casting in the mold cavity. In order to solve this technical problem, the following technical content is disclosed in this embodiment: an energy-saving cooling mechanism for centrifuge casting, comprising an outer shell 1 and a support ring 2 fixed inside the outer shell 1, a movable ring 3 is installed above the support ring 2, and a water pipe 4 at the lower end of the support ring 2 is connected to an external water supply device The outer shell 1 is connected with the equipment, and a reflux channel 5 is installed at the bottom of the outer shell 1, and a diverter column 6 is installed at the upper end of the movable ring 3, and a water spray head 7 is connected to the side of the diverter column 6. A servo motor 8 is fixed to the side of the outer shell 1, and the output end of the servo motor 8 is connected to a transmission gear 9, which is meshed with the gear ring on the edge of the movable ring 3. A power component 12 is installed on the side of the water spray head 7. The interiors of the movable ring 3 and the support ring 2 are interconnected, and the movable ring 3 can rotate on the support ring 2, and a plurality of diverter columns 6 are evenly distributed on the movable ring 3. A connecting blade 10 is fixed to the lower end of the transmission gear 9, and a heat dissipation fin 11 fixed to the reflux channel 5 is provided below the connecting blade 10.

[0040] When the mold is cooled during the centrifugal casting process, the outer shell 1 is located on the outside of the centrifugal casting mold, and the cooling water is transported to the water pipe 4 through the water supply equipment. After the water source enters the water pipe 4, the water source can be injected into the interior of the support ring 2. The water source in the support ring 2 can flow into the movable ring 3 and be sprayed outwardly onto the casting mold through the diverter column 6 and the water spray head 7 on the movable ring 3. During the water spray cooling process, the servo motor 8 is turned on. After the servo motor 8 is turned on, the transmission gear 9 can drive the movable ring 3 to rotate, and the rotation of the movable ring 3 can cause the diverter column 6 and the water spray head 7 on it to be rotated. The transmission gear 9 rotates synchronously, thereby increasing the water spraying range of the water spray head 7, so that the casting mold can be evenly cooled. The cooled water source flows into the bottom of the outer shell 1 and flows back to the water tank through the return channel 5, so that it is cooled by the refrigeration equipment in the water tank and then recycled. After the transmission gear 9 rotates, it can drive the connecting blades 10 to rotate synchronously. After the connecting blades 10 rotate, wind force can be generated. After the wind force acts on the heat dissipation fins 11 on the return channel 5, it can partially cool the hot water source flowing in the return channel 5, thereby relatively reducing the energy consumption of some refrigeration equipment.

[0041] 126 is connected to the shunt column 6 by a guide magnetic block 127, and a pressure block 128 is installed on the shunt column 6. , and the touch block 1212 and the linkage gear 121 are fitted together, a side baffle 129 is provided on the side of the pressure block 128, and the side baffle 129 is fixed on the sleeve ring 1210, an electromagnet 1211 is embedded on the side baffle 129, the sleeve ring 1210 is connected to the movable ring 3 through a one-way bearing, the sleeve ring 1210 is rotatably connected to the inside of the outer shell 1, the adjustment gear rack 122 and the linkage gear 121 are meshed, and the plug rod 1 on the adjustment gear rack 122 is connected to the inner surface of the outer shell 1. 23 can slide on the moving block 125 along the center direction of the outer shell 1, and the moving block 125 can move in the vertical direction of the diverter column 6. The outer contour of the pressure block 128 on the adjustment gear rack 122 is set to an arc structure, and the pressure block 128 corresponds to the side baffle 129 one by one, and the upper end of the side baffle 129 is also set to an arc shape. There are multiple side baffles 129 evenly distributed on the sleeve ring 1210, and each side baffle 129 is provided with an electromagnet 1211.

[0042] When the mold rotates during centrifugal casting, the servo motor 8 is turned on. After the servo motor 8 is turned on, the transmission gear 9 is rotated. After the transmission gear 9 rotates, the movable ring 3 can rotate toward the locking direction of the one-way bearing. After the movable ring 3 rotates, it can drive the sleeve ring 1210 to rotate synchronously. At this time, the movable ring 3 and the sleeve ring 1210 rotate synchronously. During the rotation of the movable ring 3, the electromagnet 1211 on the side baffle 129 is intermittently opened and closed. When the electromagnet 1211 is energized, it can generate a repulsive magnetic force on the guide magnetic block 127 on the adjustment rack 122. At this time, the adjustment rack 122 moves toward the direction of the mold, and the touch block 1212 on the adjustment rack 122 is The linkage gears 121 fit together, and when the adjusting gear rack 122 moves, the touch block 1212 can be used to drive the linkage gear 121 and the movable tube 702 to move toward the mold. When the electromagnet 1211 is powered off, the adjusting gear rack 122 is reset and rebounded under the action of the auxiliary spring 124. After the adjusting gear rack 122 is reset, the movable tube 702 and the linkage gear 121 can be reset synchronously. The reciprocating movement of the movable tube 702 can be used to knock on the centrifugal casting mold. The vibration generated by the knocking can reduce the bubbles in the mold cavity. At the same time, after centrifugal casting, when the mold needs to be cooled, the servo motor 8 is used to control the transmission gear 9 to rotate, and the rotation of the transmission gear 9 is used to make it The movable ring 3 rotates in the movable direction of the one-way bearing. At this time, the movable ring 3 does not drive the sleeve ring 1210 to rotate synchronously after the rotation. After the movable ring 3 rotates, the pressure block 128 on the adjustment gear rack 122 contacts the arc surface of the side baffle 129 on the sleeve ring 1210. The side baffle 129 can be used to squeeze the pressure block 128. At this time, the pressure block 128 drives the adjustment gear rack 122 to move upward. After the adjustment gear rack 122 moves, the moving block 125 can move on the diverter column 6. When the pressure block 128 disengages from the side baffle 129 as the movable ring 3 rotates, the adjustment gear rack 122 and the moving block 125 reset and rebound under the action of the built-in spring 126, thereby The up and down reciprocating movement of the adjusting gear rack 122 is realized. The up and down reciprocating movement of the adjusting gear rack 122 can make the meshing linkage gear 121 drive the movable tube 702 to rotate. The rotation of the movable tube 702 can disperse the water source sprayed by the movable tube 702, thereby further improving the spraying range of the water source and avoiding the cooling blind spot of the mold. It should be noted that the initial position of the pressure block 128 on the adjusting gear rack 122 is located at the highest point of the side baffle 129, and the built-in spring 126 is in a stretched state. When the movable tube 702 moves toward the center of the outer shell 1 to knock on the mold, the pressure block 128 on the adjusting gear rack 122 will not be separated from the side baffle 129.
