DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0029] Please refer to Figures 1-6 The utility model provides a kind of technical scheme: a heat dissipation mechanism for mould, including outer frame 1, the outer surface of outer frame 1 is fixedly installed with connecting rod 4, and the outer surface of one end of connecting rod 4 is fixedly installed with hydraulic cylinder 2, the output end of hydraulic cylinder 2 is through the outer surface of outer frame 1, and upper die 5 is provided between outer frame 1, and upper die 5 is fixedly installed in the output end of hydraulic cylinder 2, the outer surface of outer frame 1 is fixedly installed with lower die 6, and lower die 6 is engaged with upper die 5, pump body 10 is fixedly installed on the side surface of outer frame 1, water tank 11 is fixedly installed on the side of outer frame 1 close to pump body 10, ventilation mechanism is provided between outer frame 1 and pump body 10, and upper die 5 and lower die 6 can be cooled without contacting water by ventilation mechanism.

[0030] Connecting rod 4 can be assembled and installed together with outer frame 1, which is convenient for replacement and maintenance after damage, and the pushing of hydraulic cylinder 2 enables upper die 5 and lower die 6 to be combined and opened, so that material can be taken after cooling.

[0031] Ventilation mechanism includes: top plate 15, top plate 15 is fixedly installed on the end of outer frame 1 close to pump body 10, and the water inlet of pump body 10 is connected with water tank 11, the water outlet of pump body 10 is connected with top plate 15, and a plurality of water dripping nozzles are evenly formed on the outer surface of top plate 15, water immersion cooling fin 13 is fixedly installed on the outer surface of top plate 15, fan 8 is fixedly installed on the side of outer frame 1 away from water immersion cooling fin 13, and fan 8 and water immersion cooling fin 13 are concentrically designed.

[0032] When cooling is required, simply start the pump body 10 to draw water from the water tank 11, allowing the water to enter the top plate 15 and drain from the drip nozzles of the top plate 15. The water then soaks into the water-immersed cooling plate 13. Combined with the rotation of the fan 8 and the evaporation of water from the water-immersed cooling plate 13, the air passing through the water-immersed cooling plate 13 is quickly cooled. The cooled air quickly carries away the temperature of the upper mold 5 and the lower mold 6 without the need for water spraying for cooling, reducing the chance of deformation of the upper mold 5 and the lower mold 6 and extending their service life.

[0033] Fins 7 are fixedly installed on the outer surface of the lower mold 6, and the fins 7 are evenly distributed on the outer surface of the lower mold 6.

[0034] The fins 7 provided on the outer surface of the lower mold 6 increase the surface area of ​​the lower mold 6, allowing the temperature of the lower mold 6 to be dissipated more quickly.

[0035] A guide rod 3 is fixedly installed on the outer surface of the upper mold 5, and the outer surface of the guide rod 3 penetrates the outer surface of the outer frame 1. A copper bushing is provided between the outer frame 1 and the guide rod 3.

[0036] After the hydraulic cylinder 2 is activated and pushed out, the guide rod 3 will restrict the movement direction of the upper mold 5, so that the upper mold 5 can only move vertically up and down. This will prevent the upper mold 5 and the lower mold 6 from getting stuck due to positional displacement when they open and close. Furthermore, if displacement occurs later, the vertical movement of the upper mold 5 can be ensured by replacing the copper sleeve.

[0037] A baffle 9 is fixedly installed on the outer surface of the outer frame 1, and through holes are evenly arranged on the outer surface of the baffle 9. A protective plate 14 is fixedly installed on the outer surface of the top plate 15, and the protective plate 14 is located on both sides of the water-immersed cooling plate 13.

Furthermore, the protective plate 14 can effectively protect the water-immersed cooling plate 13 without affecting air passage, reducing the chance of the water-immersed cooling plate 13 being damaged when handling items and extending the service life of the water-immersed cooling plate 13.

[0039] A liquid cooling pipe 12 is fixedly installed on the outer surface of the outer frame 1, and one end of the liquid cooling pipe 12 is connected to the water tank 11, and the other end of the liquid cooling pipe 12 is connected to the water inlet of the pump body 10. A solenoid valve 17 is fixedly installed between the pump body 10 and the liquid cooling pipe 12, and the outer surface of the liquid cooling pipe 12 is in contact with the outer surface of the lower mold 6.

[0040] The pump body 10 is activated to draw water into the liquid cooling pipe 12, which can remove the heat from the upper mold 5 and allow the hot water to be discharged from the top plate 15. The water is cooled by the immersion cooling plate 13. When the water temperature is too high, the liquid cooling pipe 12 can be closed by the solenoid valve 17, so that the device can have multiple heat dissipation methods.

[0041] A bottom water receiving box 16 is fixedly installed at one end of the outer frame 1 near the water tank 11. The bottom water receiving box 16 has an inclined interior design and a water immersion cooling plate 13 is fixedly installed inside the bottom water receiving box 16. A water outlet is provided at one end of the bottom water receiving box 16 and the water outlet of the bottom water receiving box 16 is connected to the water tank 11. An observation window is provided on the side surface of the water tank 11.

[0042] After the water soaks the cooling pad 13, the excess water will flow into the bottom water collection box 16 and then flow back into the water tank 11 through the inclined surface of the bottom water collection box 16. The observation window on the side surface of the water tank 11 can be used to check whether water needs to be added, so that the water can be recycled and reused, reducing water waste.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
