[0029] The working principle of the retractable sole mold provided by the utility model is as follows:

[0030] When in use, the overall thickness of the lower module 7 and the lower mold frame 8 is adjusted according to the thickness of the sole to be produced. When adjusting, the dual-axis motor 9 is started to drive the two rotating shafts 10 to rotate, and the two rotating shafts 10 will drive the two first bevel gears 12 to rotate. The two first bevel gears 12 will drive the two screws 11 to rotate through the two second bevel gears 13. The rotation of the two screws 11 will cause the two screw sleeves 14 to drive the lower mold frame 8 to slide vertically on the lower module 7, so that the overall thickness of the lower module 7 and the lower mold frame 8 can be adjusted telescopically. The greater the overall thickness of the lower module 7 and the lower mold frame 8, the thicker the sole that can be formed;

[0032] Then, the cylinder 3 is started to raise the upper mold cover 4 to the initial position, and the sole material in the lower mold module 7 and the lower mold frame 8 is cooled and hardened into a sole. Then, the electric push rod 15 is started, and the electric push rod 15 drives the push block 16 to rise, and pushes the formed sole out of the lower mold module 7 and the lower mold frame 8, so as to facilitate the demolding of the sole. Then, the electric push rod 15 is started again to drive the push block 16 to descend, and move the push block 16 to the initial position, and then the staff can carry out the next sole molding work.

[0033] Compared with the related art, the retractable sole mold provided by the utility model has the following beneficial effects:

[0034] The utility model provides a retractable sole mold. The overall thickness of a lower module 7 and a lower mold frame 8 can be adjusted according to the thickness of the sole to be produced through an adjusting mechanism. The larger the overall thickness of the lower module 7 and the lower mold frame 8 is, the thicker the sole that can be formed is. The upper mold cover 4 can be pressed against the top of the lower mold frame 8 through a cylinder 3, so that a heating component 5 in the upper mold cover 4 can heat and melt the sole material in the lower module 7 and the lower mold frame 8. The melted sole material can form a sole after cooling and hardening. The pushing mechanism can facilitate the staff to demould the formed sole. The measuring rod 19 and the limiting block 20 can be used in conjunction with the staff to know the thickness of the sole that can be formed by the lower module 7 and the lower mold frame 8.
