[0027] The working principle and use process of the utility model are as follows: first, by setting the cooling component 4, when cooling the graphite mold sleeve 2, the water pump 42 can be started to circulate the water in the water tank 41 to the spiral cooling pipe 43, and the water in the spiral cooling pipe 43 absorbs the heat of the graphite mold sleeve 2 to cool the graphite mold sleeve 2. By setting the heat dissipation component 44, when the water in the water tank 41 dissipates heat, the heat conduction pipe 442 conducts the heat in the water tank 41 to the heat conduction plate 441, and the heat of the heat conduction plate 441 is absorbed by the cold end of the refrigeration plate 4431, and the heat is dissipated to the hot end through the heat dissipation plate 4432 and the heat dissipation fan 4433, so that The water in the water tank 41 is quickly cooled and refrigerated to improve the cooling effect; by setting the demolding component 5, when the graphite mold core 3 is inserted into the graphite mold sleeve 2, the graphite mold core 3 pushes the demolding rod 51 downward, so that the demolding rod 51 moves downward and squeezes the demolding spring 52. When the demolding rod 51 passes over the limiting rod 541 and reaches below the limiting rod 541, the limiting spring 542 pushes the limiting rod 541 to press against one side of the demolding rod 51 to limit the demolding rod 51. When demolding is required, it is only necessary to pull the limiting rod 541 to separate the limiting rod 541 from the demolding rod 51, and the demolding rod 51 can be lifted up under the elastic force of the demolding spring 52, which makes the operation more convenient.
