[0024] Example 1:

[0025] This embodiment Figure 1 As shown, a cooling device for mold water includes a mold 1 and a water pool 2. The mold 1 and the water pool 2 are connected through a cooling device 3. The cooling device 3 includes a transfer water tank 4, a heat exchange box 5 and a heat exchanger 6. The transfer water tank 4 is divided into a high-temperature chamber 41 and a low-temperature chamber 42 that are independent of each other. The water outlet of the water pool 2 is connected to the water inlet of the high-temperature chamber 41 through a water pump 20 and a pipe 7. The water outlet of the high-temperature chamber 41 and the water inlet of the low-temperature chamber 42 are connected to the pipe 7 through the water pump 20. The working end of the heat exchanger 6 and the heat exchange tube 8 (generally a copper tube) on the pipe 7 are both located in the heat exchange box 5. The heat exchange box 5 is filled with a heat storage agent. The water outlet of the low-temperature chamber 42 is connected to the water inlet of the mold 1 through the water pump 20 and the pipe 7. The water outlet of the mold 1 is connected to the water inlet of the water pool 2.

[0026] The cooling medium passing through the mold 1, here taking cooling water as an example, will return to the water pool after being heated for temporary storage and natural cooling. In order to improve the cooling efficiency of the cooling water and reduce heat loss, a cooling device 3 is set on the flow path between the mold 1 and the water pool 2. The high-temperature cooling water enters the high-temperature cavity 41 of the transfer water tank 4 through the water pump 20, and then the cooling water in the high-temperature cavity 41 enters the heat exchange box 5 through the water pump 20 to exchange heat with the heat storage agent (generally liquid heat storage agent). The heat storage agent in the heat exchange box 5 is heated, and the cooled cooling water returns to the low-temperature cavity 42 of the transfer water tank 4, waiting to cool the mold 1. During this heat exchange process, on the one hand, the cooling water is quickly cooled; on the other hand, the heat of the cooling medium is exchanged to the heat storage agent, which facilitates the heat exchanger 6 to extract heat from the heat storage agent for reuse.

[0027] Preferably, the transfer water tank 4 is provided with a thermometer 9 which is in communication with the high-temperature chamber 41 and the low-temperature chamber 42 respectively.

[0028] The thermometer 9 can always display the temperature of the cooling water in the high-temperature chamber 41 and the low-temperature chamber 42, making it convenient for the staff to grasp the temperature of the cooling water.

[0029] Example 2:

[0030] Based on the above embodiments, this embodiment Figure 2 As shown, the heat exchange box 5 is divided into a heating chamber 51, a pump liquid chamber 52 and a cooling chamber 53 by two partitions 10. The pump liquid chamber 52 is located between the heating chamber 51 and the cooling chamber 53. Two one-way valves 11 are symmetrically arranged on each partition 10. The heat exchange tube 8 is located in the heating chamber 51. A pump liquid mechanism 12 with a working end located in the pump liquid chamber 52 is installed on the heat exchange box 5, and the working end of the heat exchanger 6 is located in the cooling chamber 53.

[0031] The pumping mechanism 12, such as a reciprocating plunger pump, circulates the liquid heat storage agent in the heating chamber 51 and the cooling chamber 53, facilitating the mutual replacement of the cold heat storage agent and the hot heat storage agent in the partitions.

[0032] Preferably, the pumping mechanism 12 includes a piston 13, a slide rod 14, a bar frame 15, a rack 16, a fan gear 17 and a motor 18. The piston 13 is slidably installed in the pumping chamber 52, the slide rod 14 is slidably installed on the heat exchange box 5, and the inner end of the slide rod 14 is connected to the piston 13. The bar frame 15 is installed on the outer end of the slide rod 14. The rack 16 is symmetrically installed on the two vertical inner sides of the bar frame 15. The fan gear 17 is rotatably installed in the bar frame 15, and the fan gear 17 is alternately engaged with the two racks 16. The power output end of the motor 18 is connected to the fan gear 17.

[0033] The traditional reciprocating plunger pump may not be well adapted to the heat exchange box 5. The pumping mechanism 12 is installed based on the pump liquid chamber 52 of the heat exchange box 5, and cooperates well with the heating chamber 51 and the cooling chamber 53. The motor 18 is installed on the heat exchange box 5. The motor 18 drives the fan gear 17 to rotate. When the fan gear 17 rotates, it alternately engages with the two racks 16 in the bar frame 15, so that the bar frame 15 moves up and down. The piston 13 is driven by the slide rod 14 to perform a similar "reciprocating plunger motion" in the pump liquid chamber 52, and cooperates with the four one-way valves 11 to circulate the liquid heat storage agent in the heating chamber 51 and the cooling chamber 53, so as to facilitate the mutual replacement of the cold heat storage agent and the hot heat storage agent in the partition.

[0034] Preferably, a limiting block 19 adapted to the piston 13 is provided in the pump liquid chamber 52 .

[0035] The limit block 19 is used to limit the stroke of the piston 13.

[0036] Preferably, the tooth circumference length of the sector gear 17 is adapted to that of the rack 16 .

[0037] Ensure that the sector gear 17 can move up and down with the bar frame 15 by means of two racks 16.

[0038] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
