Preferably, the second string 417 is an elastic string.

Preferably, the top of the valve body 41 is provided with a through hole 418.

Preferably, as shown in fig. 8 to 11, the mold with the water cooling device further includes an upper mold body 6, the upper mold body 6 is covered on the lower mold body 3 and forms a mold cavity 61 with the lower mold body 3, an air outlet 62 is formed in the middle of the upper mold body 6, and the air outlet 62 is communicated with the through hole 418.

Preferably, the first cooling flow channel 32 is composed of a first horizontal flow channel 321, a spiral flow channel 322, a vertical flow channel 323, and a second horizontal flow channel 324, the first horizontal flow channel 321 is communicated with the second cooling flow channel 413, the lower end of the spiral flow channel 322 is communicated with the first horizontal flow channel 321, the upper end of the spiral flow channel is communicated with the upper end of the vertical flow channel 323, the lower end of the vertical flow channel 323 is communicated with the second horizontal flow channel 324, and the second horizontal flow channel 324 is communicated with the liquid outlet 325.

The working mode of the invention is as follows: as shown in fig. 3, when molten metal is not added, the temperature in the first air chamber 412 is low, so that the first sliding rod 42 pushes the control valve core 44 downward, the control valve core 44 pushes the valve plate to block the liquid inlet flow passage 511, and at this time, the second pulling ropes 417 are in a pre-tensioned state, and the control valve core 44 is in a central position because the pulling forces of the second pulling ropes 417 on the control valve core 44 are the same.

After molten metal is poured into the lower die body 3, as shown in fig. 7, the gas in the first gas cavity 412 expands due to heating, and drives the first slide rod 42 to move upward, so as to drive the control valve core 44 to move upward and fit to the upper wall of the inner cavity 411, meanwhile, the elastic member 53 pushes the valve plate 52 to rise to open the liquid inlet flow channel 511, and the cooling liquid enters the inner cavity 411 through the liquid inlet flow channel 511, and then flows out from the liquid outlet 325 through the second cooling flow channel 413, the first horizontal flow channel 321, the spiral flow channel 322, the vertical flow channel 323, and the second horizontal flow channel 324 to cool the lower die body 3. The air in the second air cavity 21 is also expanded by heat, so that the second sliding rod 22 moves downwards, the control valve core 44 is still kept in a balanced central position due to the pre-stretching length of the second pull rope 417, and the second air cavity 21 is gradually reduced as the molten metal is gradually cooled.

When the temperature of the middle part of the lower die body 3 is too fast, the gas in the second air cavity 21 at the corresponding position contracts to drive the second slide bar 22 to ascend, and further the second pull rope 417 and the first pull rope 416 are pulled to move the control valve core 44 to the corresponding side, so that the size of the connecting port between the strip-shaped opening and the inner cavity 411 is reduced, the flow of the cooling liquid in the first cooling flow channel 32 at the corresponding side is reduced, the cooling efficiency is slowed down, the flow of the cooling liquid in the first cooling flow channel 32 at the opposite side is increased, and the cooling efficiency is improved. When the temperature at this point is about the same as the temperature at other points, i.e., the other second slide bar 22 rises to the same height as the second slide bar 22 at this point, the control spool 44 returns to the center position. Similarly, when the temperature of the middle part of the lower mold body 3 is too slow, the gas in the second air cavity 21 at the corresponding position contracts too slowly, so that the contraction speed of the second pull rope 417 is slower than that of the second pull ropes 417 at other positions, and the control valve core 44 moves in the direction away from the pull ropes, so that the strip-shaped opening at the corresponding position and the connecting port of the inner cavity 411 are increased, and the flow rate of the cooling liquid is increased to improve the cooling speed.

It is worth mentioning that the movement of the control valve core 44 can synchronously change the size of the connecting port of each strip-shaped opening and the inner cavity 411, and because the heat has the characteristic of conduction, when the temperature of a certain position is too high, the peripheral side of the certain position can form a transition area with gradually changed temperature, so that the strip-shaped openings are radially arranged, the circular control valve core 44 can be effectively matched with the temperature control of the circular hub, and the phenomenon that the temperature of the certain position is too high or too low is avoided.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
