[0031] like Figures 1 to 6As shown, this utility model provides a shoe fore-upper forming mechanism, including a frame 1 that can be used for shaping the shoe fore-upper. The upper part of the frame 1 is concave. A hydraulic rod 7 is fixedly installed on the top surface of the frame 1. The output end of the hydraulic rod 7 passes through the upper part of the frame 1, and an installation plate 6 is fixedly installed on the output end of the hydraulic rod 7. The output end of the hydraulic rod 7 can drive the installation plate 6 to move. A first positioning groove is provided on both sides of the bottom surface of the installation plate 6, and a first positioning slide rail 801 matching the first positioning groove is provided in the first positioning groove. The first positioning slide rail 801 can be inserted into the first positioning groove opened at the bottom of the installation plate 6. The first positioning slide rail 801 is fixedly installed on the upper mold 8 of the shoe fore-upper. A second positioning slide rail 13 is fixedly installed on the concave upper surface of the frame 1, and a base plate 3 is provided on the second positioning slide rail 13.

[0032] In this embodiment, the upper part of the frame 1 is provided with a cavity, and a first movable plate 11 is slidably connected in the cavity. A first limiting block 2 is welded to the top surface of the first movable plate 11, which penetrates and extends to the outside of the frame 1. A third spring 12 is fixedly installed on the bottom surface of the first movable plate 11. The other end of the third spring 12 is fixedly connected to the bottom inner wall of the cavity provided in the upper part of the frame 1. A sliding groove is provided on the bottom surface of the bottom plate 3, and the sliding groove matches the second positioning slide rail 13. The sliding groove on the bottom surface of the bottom plate 3 can be inserted into the second positioning slide rail 13. Connecting rods 4 are welded on both sides of the bottom plate 3. A first limiting plate 5 is welded to the other end of the connecting rod 4, which can be used to position the front of the shoe in cooperation with the shoe front mold 9.

[0033] In this embodiment, a cavity is formed inside the mounting plate 6 near its front surface, and a second movable plate 602 is slidably connected within the cavity. Second limiting blocks 604 extending into the first positioning grooves formed on the bottom surface of the mounting plate 6 are fixedly installed on both sides of the bottom surface of the second movable plate 602. The outer sides of the second limiting blocks 604 are inclined. Three sets of first springs 603 are fixedly installed on the side of the second movable plate 602 away from the second limiting blocks 604. The other ends of the first springs 603 are fixedly connected to the top inner wall of the cavity formed in the mounting plate 6. A push-pull plate 601 is welded to one side, extending through and to the outside of the mounting plate 6. The mounting plate 6 has a through hole on one side of the front, extending through and into the cavity opened in the mounting plate 6. The push-pull plate 601 moves within the through hole. The push-pull plate 601 can be pushed upward, and the second limiting block 604 can be moved by the second moving plate 602. The second limiting block 604 can be moved out of the first positioning groove opened on the mounting plate 6. After that, the shoe front upper mold 8 can be removed from the mounting plate 6, and the replacement shoe front upper mold 8 can be limited and fixed.

[0034] In this embodiment, the upper surface of the frame 1 within the concave shape has cavities on both sides, and a second limiting plate 1003 is disposed within each cavity. A first connecting contact point 10 is fixedly installed on the top surface of the second limiting plate 1003, and a wire 1002 is installed on the first connecting contact point 10, penetrating and extending to the lower part of the second limiting plate 1003. A second spring 1001 is installed on the bottom surface of the second limiting plate 1003, surrounding the outer ring of the wire 1002. The other end of the second spring 1001 is connected to the cavity on the upper surface of the frame 1 within the concave shape. The bottom inner wall of the cavity is fixedly connected. The bottom of the shoe front lower mold 9 is provided with a groove for the first contact point 10 to be inserted, and the second contact point 14 is installed in the groove. The shoe front lower mold 9 is provided with a cavity, and an electric heating wire is installed in the cavity. The other end of the electric heating wire is connected to the second contact point 14. When the shoe front lower mold 9 is replaced, the first contact point 10 can move downward under the action of the second spring 1001, and can be connected to the second contact point 14 under the action of the second spring 1001.

[0035] Working principle and usage process of this utility model:

[0036] When in use, the shoe upper forming mechanism can place the shoe upper to be shaped between the first limiting plate 5 and the shoe upper lower mold 9. The heating wire inside the shoe upper lower mold 9 can be heated through the first contact point 10, the second contact point 14 and the wire 1002. At this time, the shoe upper lower mold 9 will heat up. Then the hydraulic rod 7 can be activated, which can make the mounting plate 6 move downward, thereby making the shoe upper upper mold 8 squeeze the shoe upper. Under the action of the shoe upper lower mold 9, the shoe upper can be shaped.

[0037] When it is necessary to replace the shoe front lower mold 9, the first limiting block 2 can be pressed to remove the shoe front lower mold 9 from the frame 1 and the first limiting plate 5 can be removed together. Then, the first limiting block 2 can be pressed down and the slide groove opened at the bottom of the upper plate 3 of the shoe front lower mold 9 to be replaced can be inserted into the second positioning slide rail 13. The first limiting block 2 can be released and the first limiting block 2 can be raised under the action of the third spring 12, which can limit and fix the installed shoe front lower mold 9. At this time, the first contact point 10 can be connected with the second contact point 14, thereby realizing the purpose of facilitating the replacement of the shoe front lower mold 9.

[0038] When replacing the shoe upper mold 8, the push-pull plate 601 can be pushed upwards, which can drive the second limiting block 604 to move through the second moving plate 602. This allows the second limiting block 604 to move out of the first positioning groove on the mounting plate 6, thereby removing the shoe upper mold 8 from the mounting plate 6. Then, the shoe upper mold 8 can be replaced. The first positioning slide rail 801 installed on the replacement shoe upper mold 8 can be inserted into the first positioning groove on the mounting plate 6. At this time, the first spring 603 presses against the second moving plate 602, which allows the second limiting block 604 to be inserted into the first positioning groove on the mounting plate 6, thereby facilitating the replacement of the shoe upper mold 8.

[0039] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
