[0041] The cooling structure 3 includes a support frame 301, a cooling frame A302, and a cooling frame B303. The support frame 301 is sleeved on the lower mold body 2. The cooling frame A302 is sleeved on the lower mold body 2. The bottom side of the cooling frame A302 supports and cooperates with the support frame 301. The cooling frame B303 is sleeved on the lower mold body 2. The cooling frame B303 supports and cooperates with the cooling frame A302, and the inner cavity of the cooling frame B303 is connected to the inner cavity of the cooling frame A302. A water inlet connector 304 is arranged on one side of the cooling frame A302, and a water outlet connector 305 is arranged on one side of the cooling frame B303. The front and rear ends of the docking point of the cooling frame B303 and the cooling frame A302 are respectively positioned and cooperated by positioning components 306.

[0042] This utility model, by setting up a support frame 301, a cooling frame A302, and a cooling frame B303, has the advantage that the cooling frames A302 and B303 can be opened and separated, allowing for separate cleaning of the inner cavities of the cooling frames A302 and B303. This solves the problem that scale on the inner wall of the water tank after prolonged cooling can affect the heat exchange effect.

[0043] Specifically, the positioning component 306 includes a fixing block 3061, an L-shaped block 3062, and a bolt 3063;

[0044] The fixing block 3061 is fixed on the cooling frame A302; the lateral end of the L-shaped block 3062 is fixed on the cooling frame B303; wherein, the longitudinal section of the L-shaped block 3062 is limited to the outer end of the fixing block 3061; the bolt 3063 is threaded through the longitudinal section of the L-shaped block 3062, and the inner end of the bolt 3063 is inserted into the opening at the outer end of the fixing block 3061.

[0045] This utility model, by setting a fixing block 3061, an L-shaped block 3062 and a bolt 3063, has the advantages of quickly fixing the cooling frame A302 and the cooling frame B303 after they are connected, and is also easy to disassemble.

[0050] Working principle: Using the device of this utility model, cooling frames A302 and B303 are docked and fixed. The water inlet connector 304 is connected to the cooling water inlet pipe to introduce cooling water. After heat exchange, the cooling water is discharged from the water outlet connector 305, achieving automatic cooling. Cooling frames A302 and B303 are periodically disassembled, separating the upper mold body 1 and the lower mold body 2. The bolt 3063 is rotated outwards until its inner end leaves the outer opening of the fixing block 3061. Cooling frames A302 and B303 are then removed. After separation, the inner cavity is cleaned. The cleaned cooling frames A302 and B303 are then sequentially fitted onto the lower mold body 2 and docked. The bolt 3063 is rotated in the opposite direction until its inner end inserts into the outer opening of the fixing block 3061 for fixation.

[0051] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations.
