A precision plastic mold molding placement chamber 14 is installed inside the cooling box 1. The precision plastic mold molding placement chamber 14 is fixedly installed above the rotating chassis 15. A direction-changing transmission box 17 is installed below the rotating chassis 15. The direction-changing transmission box 17 is connected to the motor 18. The cooling box 1 is connected to the filter element 10 through a hole formed on the side wall and located above the rotating chassis 15. The filter element 10 is connected to the coolant between the cooling box 1 and the pressure pump 5 through a coolant recovery pipe 9. The supply tank 8 is connected, the coolant supply tank 8 is connected to the booster pump 5 through the coolant suction pipe 7, the side wall of the booster pump 5 is electrically connected to the operation panel 6, the booster pump 5 is connected to the three-way diverter valve 3 through the coolant discharge pipe 4, and three atomizing nozzles 301 located inside the cooling box 1 are installed at the end of the three-way diverter valve 3. The three-way diverter valve 3 is arranged above the filter element 10. Controlling the operation of the booster pump 5 and the motor 18 through the operation panel 6 is a mature existing technology and is widely used in various aspects such as chemical industry, bridges, roads, etc., so I will not go into details here.

[0022] Specifically, the bottoms of the cooling box 1, the coolant supply tank 8, and the pressure pump 5 are all fixedly mounted on the integrated base 12. The integrated base 12 is a stainless steel structure with a sandwich layer. This arrangement facilitates laying cables in the integrated base 12, avoiding the clutter caused by exposed cables, thereby increasing the overall neatness.

[0023] Specifically, a universal wheel 13 is installed at the bottom of the integrated base 12, and a self-locking device is provided on the universal wheel 13. This arrangement makes it easy to move the device at any time, thereby improving the flexibility of the device.

[0024] Specifically, a maintenance cover 2 is detachably mounted on the top of the cooling box 1 by bolts. This arrangement facilitates opening the maintenance cover 2 when necessary to inspect and maintain various devices inside the cooling box 1.

[0025] Specifically, a plurality of heat sinks 1401 are formed on the shell of the precision plastic mold forming and placement chamber 14, and a thermal conductive adhesive 1402 is adhered to the inner wall of the precision plastic mold forming and placement chamber 14. The thermal conductive adhesive 1402 provides positioning for the precision plastic mold, and the heat of the precision plastic mold is dissipated to the shell of the precision plastic mold forming and placement chamber 14 through the thermal conductive adhesive 1402 and dissipated through the heat sink 1401.

[0026] Specifically, the rotating chassis 15 is rotatably sealed with the cooling box 1 via a rotating sealing ring 16 . This arrangement can prevent the coolant from leaking through the gap to the bottom and causing damage to the motor 18 .

[0027] Specifically, a liquid level gauge 11 is provided in the coolant supply tank 8, a liquid filling port 19 is formed on the top of the coolant supply tank 8, and a net bag 20 is fixed below the liquid filling port 19.

[0028] Working principle: When using this device to cool precision plastic mold molding, first connect this device to the external power grid through the operation panel 6, and the external power grid will power this device, and inject the coolant into the coolant supply tank 8 through the liquid injection port 19 for standby use, then place the precision plastic mold to be cooled in the precision plastic mold molding placement chamber 14, and use the thermal conductive glue 1402 to provide positioning for the precision plastic mold, and use the thermal conductive glue 1402 to dissipate the heat of the precision plastic mold to the shell of the precision plastic mold molding placement chamber 14, and dissipate it through the heat sink 1401, then input the working instruction through the operation panel 6, and the operation panel 6 controls the pressure pump 5 to draw the coolant in the coolant supply tank 8 through the coolant suction pipe 7 and pressurize it Finally, the coolant is introduced into the three-way diverter valve 3 through the coolant discharge pipe 4, diverted to the atomizing nozzle 301, and then atomized and sprayed out, and sprinkled on the shell of the precision plastic mold molding placement chamber 14. At the same time, the operation panel 6 controls the motor 18 to output power through the reversing transmission box 17, and the reversing transmission box 17 drives the rotating chassis 15 to rotate. The rotating chassis 15 drives the precision plastic mold molding placement chamber 14 and the precision plastic mold in the precision plastic mold molding placement chamber 14 to rotate, so that the coolant is evenly sprayed on the heat sink 1401. The heat sink 1401 expands the contact area, thereby improving the heat dissipation efficiency of the precision plastic mold. The coolant scattered above the rotating chassis 15 is filtered by the filter element 10 and then introduced into the coolant supply tank 8 for recycling.
