The cooling structure 7 includes a cooling fin 71 fixedly connected to the outer surface of the side mold plate 61 and a cold water tank 72 and a hot water tank 73 connected to the cooling fin 71. The cold water tank 72 is connected to the cooling fin 71 through a water inlet pipe 74, and the hot water tank 73 is connected to the cooling fin 71 through a water outlet pipe 75. The cold water tank 72 and the hot water tank 73 are isolated from each other by a heat insulation plate 710.

A recovery box 94 is installed on the side of the liquid metal electromagnetic pump 93. The recovery box 94 is connected to the output end of the liquid metal electromagnetic pump 93, so that the excess casting liquid poured into the lower mold plate 62 can flow out from the overflow groove 91 and be recovered to the recovery box 94 under the extrusion of the upper mold 4 and the suction of the liquid metal electromagnetic pump 93, waiting to be reheated and used. At the same time, under the extrusion of the upper mold 4 and the suction of the liquid metal electromagnetic pump 93, the casting liquid can fill all parts of the lower mold plate 62, thereby greatly improving the quality of the flange.

[0040] The specific implementation method is as follows: during use, during use, the staff first turns on the heating wire 64 in the lower template 62, so that the heating wire 64 heats the heating chamber 63, thereby increasing the temperature of the surface of the lower template 62, thereby avoiding the formation of cracks or bubbles and unevenness on the surface and inside of the flange during flange formation due to the temperature of the lower template 62 being too low, which greatly reduces the quality of the flange. After the temperature of the lower template 62 rises, the staff pours the casting liquid into the lower template 62, and at the same time, the staff controls the electric slider 22 to press down, thereby driving the lower pressing plate 23 to press down, so that the upper mold 4 slowly fits with the lower template 62 until the upper mold 4 is engaged in the lower template 62. During the extrusion process of the upper mold 4, it is beneficial for the casting liquid to fill every corner of the lower template 62. While pressing the mold, the liquid metal electromagnetic pump 93 is started, and under the extrusion of the upper mold 4, the excess metal outside the lower template 62 is The casting liquid can be sucked by the liquid metal electromagnetic pump 93 through the suction pipe 92 and the overflow groove 91, and discharged into the recovery box 94 for recycling, waiting to be reheated and used, effectively avoiding unnecessary waste. When the casting liquid is poured into the lower mold 6, the staff turns off the heating wire 64 and adds cooling water through the water inlet 78, so that the cooling water enters the cold water tank 72 and enters the cooling fin 71 from the water inlet pipe 74. Under the action of the first ring plate 76 and the second ring plate 77, the lower mold 62 is cooled by the side mold plate 61. The cooling water that has absorbed the heat enters the hot water tank 73 from the outlet pipe 75, and is then discharged from the outlet 79, thereby achieving the effect of cooling the casting liquid. When the casting liquid is cooled, the staff controls the electric push rod 82 to shrink downward, so that the lower mold plate 62 is separated from the side mold plate 61, which makes it convenient for the staff to take out the flange, saving time and effort, and greatly improving practicality.
