[0022] In order to make the structure and advantages of the present invention more clear, the structure of the present invention will be further described below with reference to the accompanying drawings.

[0023] The front, back, left and right described in this embodiment are all relative positions and do not limit the use direction of the specific structure.

[0024] A bolt-free quick mold change structure, see attached Figure 1 As shown, it includes a bottom mold frame 27, a bottom module 21, a side mold frame 11, and a side module 12. The bottom mold frame 27 and the side mold frame 11 are both rectangular cube frame structures. The upper end of the bottom mold frame 27 is limitedly connected to the bottom module 21, and the bottom module 21 is detachable; the upper end of the side mold frame 11 is fixedly connected to the side module 12.

[0025] The bottom mold frame 27 and the side mold frame 11 can be relatively buckled, so that the bottom module 21 and the side module 12 are positioned and matched to form the groove of the sole. According to the soles of different sizes, the bottom module 21 and the side module 12 of the corresponding size need to be replaced.

[0026] See attached Figure 3 As shown. One side of the side mold frame 11 is hinged to the bottom mold frame 27. In order to achieve quick connection, the side mold frame 11 and the bottom mold frame 27 adopt a plug-in matching structure. The specific structure is as follows:

[0027] A top plate 24 is fixed to the upper end of the bottom mold frame 27, and a slot 22 is provided in the middle of one side of the top plate 24;

[0028] One side of the side mold frame 11 is connected to a flip shaft 13, and a connector 14 is rotatably mounted on the flip shaft 13. The connector 14 matches the size of the slot 22 and can be inserted into the slot without shaking.

[0029] See attached Figure 2 As shown, the specific structure of the connector 14 includes a sleeve 141, a connecting plate 142, a flat plate 143, and an insert 144. The sleeve 141 is assembled on the tilt shaft 13 and can rotate around the tilt shaft 13 but cannot move axially. One end of the connecting plate 142 is fixed to the radial outer wall of the sleeve 141. The other end of the connecting plate 142 is fixed to one end of the flat plate 143. The other end of the flat plate 143 is fixed to the insert 144. The size of the insert 144 matches the size of the slot 22 of the bottom mold frame 27. The connecting plate 142, flat plate 143, and insert 144 are arranged vertically at 90 degrees. When the insert 144 is installed in the slot 22, the upper end surface of the flat plate 143 is flush with the upper end surface of the top plate 24. This ensures that when the bottom module 21 is installed on the top plate 24, the lower end surface of the bottom module 21 abuts the flat plate 143, thereby locking the position of the connector 14.

[0030] A limiting groove is provided in the middle of the top plate 24, and the bottom module 21 is inserted into the limiting groove and connected to the bottom mold frame 27. The side of the bottom module 21 close to the flip axis 13 abuts against the upper end of the plug-in component 14, so that the plug-in is fixed in the slot 22, thereby realizing the hinge connection between the side mold frame 11 and the bottom mold frame 27 without the assistance of bolts. Figure 4 、 5 shown.

[0031] In order to ensure the rapid positioning and locking of the bottom module 21, see the attached Figure 6 As shown, a locking piece 26 for locking the bottom module 21 is installed in the bottom mold frame 27 below the top plate 24. The locking piece 26 is an oblong structure. A rotating shaft is connected to the middle of the locking piece 26, and the rotating shaft is fixedly connected to the lower end of the top plate 24. A handle is connected to the side of the locking piece 26. Pushing the handle can drive the locking piece 26 to rotate, thereby rotating the two major diameter ends of the oblong shape to an angle, so as to insert or leave the positioning groove at the lower end of the bottom module 21.

[0032] Two positioning blocks are fixedly installed at the lower end of the bottom module 21, and positioning grooves are provided on the opposite sides of the two positioning blocks. When the bottom module is installed on the bottom mold frame, the positioning blocks pass through the through holes on the top plate so that the positioning grooves are located below the top plate; the size of the positioning grooves can match the locking plate, and when the long diameter end of the locking plate is rotated to insert into the positioning groove, the bottom module is locked. When the long diameter end of the locking plate is rotated out of the positioning groove, the bottom module can be freely removed.

[0033] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
