[0002] Shoes are important daily necessities that facilitate walking and protect feet from injury. The sole is one of the main components of shoes. After the sole is produced, the upper is sewn or glued to the sole to form the shoe.

[0039] The cooling mechanism 30 includes a heat dissipation component 31 and a water cooling component. The heat dissipation component 31 includes a heat conducting plate 311, a heat dissipation fin 312 and a heat dissipation fan 313.

[0043] Specifically, in another embodiment of the present invention, Figure 1 As shown, the refrigeration component 322 includes a water pump 322a, a refrigerator 322b and a water tank 322c. One end of the water pump 322a is connected to the lower mold base 20, and the other end is connected to the refrigerator 322b.

During refrigeration, the water pump 322a and the refrigerator 322b are started one by one, and the water in the water tank 322c is refrigerated by the refrigerator 322b, and then the cooling water is pumped into the cooling component 323 by the water pump 322a, and the heat is discharged by the cooling water, and the exchanged cooling water is discharged back to the water tank 322c, so as to achieve rapid cooling.

[0044] The cooling component 323 includes a cooling pipe 323a and a plurality of groups of shunt pipes 323b. The cooling pipe 323a is arranged below the molding groove 21. The plurality of groups of shunt pipes 323b are evenly distributed on the cooling pipe 323a, and the top of the shunt pipe 323b is connected to the cooling pipe 323a. The inlet end of the cooling pipe 323a is connected to the water pump 322a, and the outlet end of the cooling pipe 323a is connected to the water tank 322c.

[0048] Specifically, in another embodiment of the present invention, Figure 4-Figure 5 As shown, the upper mold base 10 is provided with a plurality of groups of circumferentially arranged limiting columns 14. The lower mold base 20 is provided with a plurality of groups of limiting grooves 23 corresponding to the limiting columns 14. When the mold is closed, the limiting columns 14 and the limiting grooves 23 cooperate with each other to prevent the upper mold base 10 and the lower mold base 20 from having position deviation, thereby improving the position accuracy of the shoe mold and the production quality of the sole.

[0049] By setting the heat dissipation component 31 and the water cooling component, when the upper mold base 10 and the lower mold base 20 are closed, the heat in the molding groove 21 is transferred through the heat conduction plate 311, and the heat is quickly discharged to the outside through the action of the heat dissipation fins 312 and the heat dissipation fan 313. At the same time, the temperature in the shoe mold is monitored by the temperature sensor 321. When the temperature reaches the preset value, the water pump 322a and the refrigerator 322b are started one by one, and the refrigerated water is pumped into the cooling component 323 by the water pump 322a.
