The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] This utility model embodiment provides a shoe sole mold with an adjustable cavity, such as Figure 1-5 As shown, the adjustable cavity shoe sole mold includes: a lower mold base 1, on both sides of the lower mold base 1, mounting brackets 2 are fixedly installed, and an upper mold base 3 is slidably installed on the two mounting brackets 2. The inner wall of the upper mold base 3 is provided with two upper molds 4; two cavities 5, both of which are located on the lower mold base 1, and a lower mold 6 is slidably installed in each of the two cavities 5; a mounting groove 7, which is located on the lower mold base 1; and an adjustment mechanism, which is located on the mounting groove 7 and is used to adjust the position of the lower mold 6 in the cavity 5.

[0023] In this embodiment, the lower mold base 1 serves as the basic support structure for the entire mold. Two mounting brackets 2 are fixedly installed on the lower mold base 1 to support and slide the upper mold base 3. The upper mold base 3 is slidably mounted on the two mounting brackets 2. The inner wall of the upper mold base 3 is provided with two upper molds 4, which cooperate with the lower mold 6 to form a complete cavity. The lower mold base 1 is provided with two cavities 5, and the lower mold 6 is slidably mounted in each cavity 5. By adjusting the position of the lower mold 6 in the cavity 5, the size of the cavity can be changed, thereby adapting to the production needs of shoe soles of different thicknesses. The lower mold base 1 is provided with mounting grooves 7 for adjustment. The adjustment mechanism is located on the mounting groove 7 and is used to precisely adjust the position of the lower mold 6 within the cavity 5. Traditional shoe sole mold cavities have a fixed depth, which cannot adapt to the production needs of shoe soles of different thicknesses. By adjusting the mechanism, the position of the lower mold 6 within the cavity 5 can be precisely adjusted, thereby changing the size of the cavity and achieving the effect of one mold for multiple uses. This flexibility allows the mold to adapt to the production needs of shoe soles of different styles and thicknesses, greatly improving the flexibility and efficiency of production. At the same time, due to the increased versatility of the mold, the time for mold replacement and debugging is reduced, further reducing production costs.

[0024] In a further preferred embodiment of this utility model, the adjusting mechanism includes two threaded cylinders 8, two threaded rods 9, a rotating rod 10, four sprockets 11, and two chains 12. The two threaded cylinders 8 are rotatably installed in the mounting groove 7. The two threaded rods 9 are respectively threaded onto the two threaded cylinders 8, and the top ends of the two threaded rods 9 are respectively fixed to the bottoms of the two lower molds 6. The rotating rod 10 is rotatably installed in the mounting groove 7. The four sprockets 11 are respectively disposed on the two threaded cylinders 8 and the rotating rod 10, and the two chains 12 are respectively sleeved on the four sprockets 11.

[0025] In this embodiment, two threaded cylinders 8 are rotatably installed in the mounting groove 7, serving as the basic support and rotating component of the adjustment mechanism. Two threaded rods 9 are respectively threaded onto the two threaded cylinders 8. The rotation of the threaded cylinders 8 realizes the lifting and lowering movement of the threaded rods 9. The rotating rod 10 is connected to the threaded cylinders 8 through sprockets 11 and chains 12, and is used to drive the rotation of the threaded cylinders 8. Four sprockets 11 are respectively installed on the threaded cylinders 8 and the rotating rods 10. Two chains 12 pass around the sprockets 11 to form a chain drive system. The chain drive system is used to synchronize or link the rotation of the two threaded cylinders 8, ensuring that the two threaded rods 9 can lift and lower synchronously. The top ends of the two threaded rods 9 are respectively fixed to the bottom of the two lower molds 6. The lifting and lowering movement of the threaded rods 9 drives the lower molds 6 to slide in the cavity 5, thereby adjusting the size of the cavity. This precise adjustment helps to meet the production needs of shoe soles of different thicknesses and improves the dimensional accuracy and quality stability of the product.

[0026] In a further preferred embodiment of the present invention, the mounting bracket 2 is provided with a sliding groove 13, a sliding rod 14 is fixedly installed in the sliding groove 13, a sliding seat 15 is slidably installed on the sliding rod 14, and the sliding seat 15 is fixed to the upper mold base 3.
