[0038] In one embodiment of the present invention, Figure 1-Figure 6As shown, a shoe mold for adjusting the thickness of the sole is provided, including an upper mold base 10 and a lower mold base 20.

The adjustment mechanism 30 is arranged above the molding protrusion 11, and the adjustment mechanism 30 includes an adjustment drive 31, a lifting plate 32 and a connecting block 33. The adjustment drive 31 is a cylinder, and the output end of the adjustment drive 31 is connected to the lifting plate 32, the lifting plate 32 is connected to the connecting block 33, and the connecting block 33 is connected to the top of the molding protrusion 11. Both ends of the lifting plate 32 are provided with guide columns 36 for sliding connection, and the lifting plate 32 is provided with a buffer layer 34 and a plurality of groups of buffer protrusions 35.

[0039] In this embodiment, the buffer layer 34 and the buffer protrusion 35 are both made of rubber material. By providing the buffer layer 34 and the buffer protrusion 35, the lifting plate 32 is prevented from colliding with the upper mold base 10 when the adjustment mechanism 30 runs to the upper and lower limit positions, thereby improving the service life of the shoe mold.

[0040] Before the sole is formed, the lifting plate 32 and the connecting block 33 are driven upward or downward by adjusting the driving member 31, and the height position of the forming protrusion 11 relative to the forming recessed block 22 is adjusted, thereby adjusting the thickness of the sole after forming, simplifying the adjustment operation steps. At the same time, a lifting mechanism 60 is also provided. After the sole is formed, the lifting mechanism 60 is used to lift the sole from the forming recessed block 22, which is convenient for the staff to take the material and improves the production efficiency.

The temperature sensor 42 is arranged on the inside of the molding concave block 22, and is used to detect the temperature in the lower mold base 20. The temperature in the lower mold base 20 is detected by the temperature sensor 42. When the temperature exceeds the preset value, the heat dissipation component 41 is activated, which discharges the heat in the lower mold base 20 to the outside, thereby improving the heat dissipation effect of the shoe mold.

The heat in the forming concave block 22 is quickly transferred to the heat dissipation fan 412 through the heat conducting plate 411, and the heat is discharged to the outside through the heat dissipation fan 412, thereby improving the heat dissipation effect of the shoe mold, and also by setting the filter 413, dust from the outside is prevented from entering the lower mold base 20, thereby preventing the accumulation of dust from affecting the heat dissipation effect of the heat dissipation assembly 41.

[0043] A digital display 23 is provided on the lower mold base 20. The digital display 23 is electrically connected to the temperature sensor 42 and is used to display the temperature inside the lower mold base 20.

The cooling pipe 51 is arranged below the molding concave block 22. The plurality of groups of manifolds 52 are evenly distributed on the cooling pipe 51, and the top of the manifold 52 is connected to the cooling pipe 51. In this embodiment, the input end and the output end of the cooling pipe 51 are both connected to an external water tank, and the cooling water in the water tank is passed into the cooling pipe 51 and the manifold 52 to achieve water-cooled conduction heat dissipation and improve the heat dissipation effect of the shoe mold.

[0045] Specifically, in another embodiment of the present invention, Figure 2 As shown, the ejection mechanism 60 includes a fixed plate 61 and an ejection assembly 62.

By providing the guide column 36 in the mounting cavity 15, the lifting plate 32 can stably move up and down during movement, preventing the lifting plate 32 from moving unstably, and improving the service life of the adjustment mechanism 30.

[0047] Specifically, in another embodiment of the present invention, Figure 5-Figure 6 As shown, the upper mold base 10 is provided with a plurality of groups of circumferentially arranged limiting columns 12. The lower mold base 20 is provided with a plurality of groups of limiting grooves 24 corresponding to the limiting columns 12. When the mold is closed, the limiting columns 12 and the limiting grooves 24 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.

[0048] By setting up the adjustment mechanism 30, before the sole is formed, the lifting plate 32 and the connecting block 33 are driven to move upward or downward by adjusting the driving member 31, and the height position of the forming protrusion 11 relative to the forming recessed block 22 is adjusted, thereby adjusting the thickness of the sole after forming, simplifying the adjustment operation steps. At the same time, a lifting mechanism 60 is also set. After the sole is formed, the lifting mechanism 60 is used to lift the sole from the forming recessed block 22, which is convenient for the staff to take the material and improves the production efficiency.
