[0026] Please refer to Figures 1-6 As shown in the figure, which shows the specific structure of the preferred first embodiment of the utility model, it is a mold cooling structure, including the upper die 10 and the main flow channel 20 in the upper die 10, the sleeve 30 is sleeved on the main flow channel 20, the main flow channel 20 and the sleeve 30 are provided with the cooling flow channel 40 which is communicated, the inlet and outlet of the cooling flow channel 40 are communicated with the first water inlet 11 and the first water outlet 12 on the upper die 10. When the solution passes through the main flow channel 20, the heat of the solution is conducted to the main flow channel 20, in order to avoid the damage of the main flow channel 20 due to high temperature, the cooling flow channel 40 is arranged on the main flow channel 20 and the sleeve 30, and the cooling flow channel 40 is communicated with the first water inlet 11 and the first water outlet 12 arranged on the upper die 10, the cooling liquid enters the cooling flow channel 40 through the first water inlet 11, and finally flows out of the first water outlet 12, so as to cool the main flow channel 20.

[0027] As Figure 2 shown, the cooling flow channel 40 includes the first flow channel 41 provided with the outer wall of the sleeve 30 and the second flow channel 42 provided on the outer wall of the main flow channel 20, the sleeve 30 is provided with the second water inlet 31 communicated with the first water inlet 11, and the first flow channel 41 is communicated with the second flow channel 42 through the second water inlet 31. In order to effectively cool the sleeve 30 and the main flow channel 20, the cooling flow channel 40 is divided into the first flow channel 41 arranged on the outer wall of the sleeve 30 and the second flow channel 42 arranged on the outer wall of the main flow channel 20, the first flow channel 41 and the second flow channel 42 are communicated, and the liquid in the first flow channel 41 can enter the second flow channel 42, because the first flow channel 41 is located on the outer wall of the sleeve 30, when the solution in the main flow channel 20 conducts heat, the temperature of the sleeve 30 is lower than that of the main flow channel 20, the liquid in the first flow channel 41 can effectively cool the sleeve 30, and then enter the second flow channel 42 again, which can still effectively cool the main flow channel 20, so as to achieve better cooling effect.

[0028] As Figure 3 shown, the sleeve 30 is provided with the second water outlet 32 communicated with the first water outlet 12 and the second flow channel 42, and the second water outlet 32 corresponds to the outlet of the second flow channel 42. After the liquid enters the second flow channel 42 from the first water inlet 11 and the second water inlet 31, it flows through the second flow channel 42 to the second water outlet 32 and is discharged from the first water outlet 12, forming a complete cooling loop.

[0029] As Figure 4As shown, for example, the first flow channel 41 is a spiral groove 411 provided on the surface wall of the sleeve 30. The water outlet end of the spiral groove 411 is connected to the second water inlet 31. The inner cavity of the upper mold 10 is provided with a guide groove 13 connecting the first water inlet 11 and the water inlet end of the spiral groove 411. In order to allow the liquid flowing in the first flow channel 41 to enter the second flow channel 42 through the second water inlet 31, the first flow channel 41 is set as a spiral groove 411, and the water inlet end of the spiral groove 411 is located at the lower part of the sleeve 30, and the water outlet end of the spiral groove 411 is located at the upper part of the sleeve 30. The first water inlet 11 is connected to the spiral groove 411 through the guide groove 13. At this time, when the cooling liquid enters the first water inlet 11, part of it will enter the second water inlet 31 and part of it will enter the guide groove 13, thereby forming a bidirectional cooling system.

[0030] like Figure 5 As shown, exemplarily, the second flow channel 42 includes a first guide groove 421 communicating with the second inlet 31 and a second guide groove 422 communicating with the second outlet 32. The first guide groove 421 and the second guide groove 422 are connected by a third guide groove 423. The connection between the first guide groove 421, the second guide groove 422, and the third guide groove 423 allows cooling water to enter the first guide groove 421 through the second inlet 31, flow into the third guide groove 423 along the first guide groove 421, and then into the second guide groove 422 through the third guide groove 423, finally exiting through the second inlet 31.

[0031] The first guide groove 421 and the second guide groove 422 are arranged vertically and recessed around the main channel 20.

[0032] The inner wall of the sleeve 30 is adapted to the outer wall of the main channel 20, and the sleeve 30 is adapted to the inner cavity of the upper mold 10 so that the liquid cooling the main channel 20 flows in the cooling channel 40.
