[0042] The lower fixing structure 12 in this embodiment includes a connecting seat 121, a slide rod 122, a third spring 123, a support rod 124, and a hinge shaft 125. The connecting seat 121 is disposed on the upper fixing structure 11. The slide rod 122 and the third spring 123 are both disposed inside the connecting seat 121, and the two ends of the third spring 123 abut against the connecting seat 121 and the slide rod 122 respectively. The support rod 124 is disposed on the slide rod 122 through the hinge shaft 125. A torsion spring is fitted on the hinge shaft 125, and the two ends of the torsion spring abut against the support rod 124 and the slide rod 122 respectively. A connecting post 1211 is disposed on the upper part of the connecting seat 121. A locking hole 1212 is disposed on the connecting post 1211, and the locking hole 1212 is engaged with the locking block 116. The elastic force of the third spring 123 is greater than the elastic force of the torsion spring, which is not shown in the figure.

[0043] In this embodiment, the lower part of the connecting seat 121 is provided with a first connecting sleeve 1213, which is connected to a second connecting sleeve 1214. The first connecting sleeve 1213 and the second connecting sleeve 1214 are respectively provided with a first connecting groove 1215 and a second connecting groove 1216. The upper end of the slide rod 122 is connected to the slide rod sleeve 1221 through the connecting slider 1222. The slide rod sleeve 1221 is fitted outside the first connecting sleeve 1213. The connecting slider 1222 is located inside the first connecting groove 1215. The lower end of the slide rod 122 is provided with a slide rod limiting seat 1223, which is tapered and located inside the second connecting sleeve 1214.

[0044] Specifically, the shoe upper fixing structure 1 used for the molding mechanism pre-suspends the shoe upper on the lower fixing structure 12 during operation. The sliding sleeve 1221 is slid upward to compress the third spring 123. At the same time, under the action of the torsion spring, the support rod 124 can rotate along the hinge axis 125, putting the support rod 124 in a retracted state. Then, the second connecting sleeve 1214 is inserted into the shoe upper guide. The sliding sleeve 1221 is released, and under the action of the third spring 123, the support rod 124 is opened, thus suspending the shoe upper on the lower fixing structure 12.

[0045] The turntable motor 7 drives the turntable bushing 5 to rotate the upper turntable 3 and the lower turntable 4. When the upper turntable 3 and the lower turntable 4 rotate to the shoe upper loading station, the connecting post 1211 is inserted into the connecting hole 1124. At the same time, under the action of the locking block 116, the locking block 116 can be locked into the locking hole 1212. The lower fixing structure 12 with the shoe upper suspended and the upper fixing structure 11 are assembled at the shoe upper loading station.

[0046] The turntable motor 7 drives the turntable bushing 5 to rotate the upper turntable 3 and the lower turntable 4. When the upper turntable 3 and the lower turntable 4 rotate to the shoe mold loading station, the shoe mold is placed in the shoe mold fixing groove 22.

[0047] The turntable motor 7 drives the turntable bushing 5 to rotate the upper turntable 3 and the lower turntable 4. When the upper turntable 3 and the lower turntable 4 rotate to the pressing position, the pressure rod head 1121 contacts the pressing head with a spiral structure. As the turntable motor 7 rotates, the shoe upper and the shoe mold can be pressed together. When the pressure rod head 1121 is separated from the pressing head, the shoe upper and the shoe mold are suspended together on the lower fixed structure 12.

[0048] The turntable motor 7 drives the turntable bushing 5 to rotate the upper turntable 3 and the lower turntable 4. When the upper turntable 3 and the lower turntable 4 rotate to the unloading station, the sliding sleeve 114 is threadedly connected to the sleeve 111. By rotating the sliding sleeve 114, the sliding sleeve 114 moves downward on the sleeve 111. Since the sliding sleeve 114 and the slider 115 are connected through the slider limiting groove 1141 and the slider limiting block 1151, the sliding sleeve 114 can drive the slider 115 to move downward when it rotates and descends. When the wedge block 1152 contacts the wall of the wedge hole 1161, it can pull the locking block 116 outward, so that the locking block 116 is disengaged from the locking hole 1212. Thus, the upper fixed structure 11 and the lower fixed structure 12 can be separated, and the pressing mold is completed.

[0049] By repeatedly sliding the slide sleeve 1221 upwards, the lower fixed structure 12 and the molded shoe upper and shoe mold can be removed.

[0050] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components, etc. The above description is merely illustrative of the structure of the present invention. All equivalent or simple variations made based on the structure, features, and principles described in this patent concept are included within the protection scope of this patent. Those skilled in the art can make various modifications or additions to the described specific embodiments or use similar methods to substitute them, as long as they do not deviate from the structure of the present invention or exceed the scope defined by the claims, all of which should fall within the protection scope of this invention.
