[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1 to 3

[0022] A movable sewing mold for three-dimensional webbing includes a base 1 and a base plate 2 disposed on the base 1. A template 3 for pressing down part of the shoe heel 8 is disposed above the base plate 2. A receiving space for accommodating the shoe heel 8 is formed between the base plate 2 and the template 3. The template 3 is driven by a lifting mechanism 4 to move towards / away from the base plate 2. When the template 3 is close to the base plate 2, the template 3 presses down on the shoe heel 8 disposed on the base plate 2; when the template 3 is away from the base plate 2, the shoe heel 8 without sewn webbing 9 can be placed on the base plate 2, or the shoe heel 8 with sewn webbing 9 can be removed. It is worth noting that the lifting mechanism 4 in this embodiment is the same as the lifting mechanism 4 conventionally used in sewing machines, and will not be described in detail here.

[0023] The base plate 2 is provided with a base plate sewing groove for sewing webbing 9 and two lifting pieces 21 for lifting the raised area of ​​the heel 8. The two lifting pieces 21 are symmetrically arranged on both sides of the base plate sewing groove. The base plate sewing groove can restrict the trajectory of the sewing needle for sewing webbing 9.

[0024] The template 3 is provided with a template sewing groove 31 that matches the bottom plate sewing groove, and a receiving groove 32 for accommodating the two upturned pieces 21 when the template 3 is close to the bottom plate 2. The two upturned pieces 21 are correspondingly arranged in the two receiving grooves 32, and both the template sewing groove 31 and the two receiving grooves 32 extend through the upper and lower ends of the template 3. Specifically, the template sewing groove 31 matches the shape of the webbing 9, and the receiving groove 32 can avoid the upturned pieces 21 with the upturned part of the shoe heel 8. The receiving groove 32 is correspondingly arranged with the upturned pieces 21. Figure 3 When the template 3 moves downwards and approaches the base plate 2, the lifting member 21 lifts the raised part of the shoe heel 8 upwards and places it in the receiving groove 32; that is, when the webbing 9 is placed on the template sewing groove 31, the lifting member 21 can lift the part of the shoe heel 8 that needs to be lifted, which can ensure that the webbing 9 and the shoe heel 8 can be lifted to form a free space.

[0025] Furthermore, the base plate 2 and the cover plate 3 can be made of nylon or ABS resin, preferably ABS resin. The upper surface of each upturned part 21 has an arc-shaped structure, which is adapted to the curvature of the upturned part of the heel 8. The outline of the upturned part 21 can match part of the outline of the heel 8. When the heel 8 is placed on the upturned part 21 and inserted into the receiving groove 32, the upturned part 21 and the receiving groove 32 can prevent the heel 8 from loosening.

[0026] It is understood that this utility model, by providing a template sewing groove 31 on the template 3 to restrict the trajectory of the sewing needle, and a receiving groove 32 that matches the shape of the webbing 9, allows the raised part of the heel 8 to be fixed on the raised part 21 of the base plate 2 when the webbing 9 needs to be sewn to the heel 8. The template 3 moves downward and covers the base plate 2, and the webbing 9 can be placed on the template sewing groove 31. The base plate sewing groove is correspondingly set with the template sewing groove 31. The sewing needle can pass through the template sewing groove 31 and sew the webbing 9 along the trajectory of the base plate sewing groove. In this way, when sewing the webbing 9 to the heel 8, it is not necessary to print threads and apply glue to the heel 8, which will not cause pollution to the heel 8 and can improve the appearance of the heel 8.

[0027] In addition, the base plate 2 is provided with two symmetrically arranged lifting parts 21. When the webbing 9 is placed on the template sewing groove 31, the lifting parts 21 can lift the part of the heel 8 that needs to be lifted to form a free space. The combined action of the lifting parts 21 and the template 3 can make the lifting degree of the free space between the heel 8 and the webbing 9 consistent and the spacing uniform, which can improve the quality of the shoe. Moreover, this device can standardize the sewing operation of the webbing 9 and can be applied to computerized sewing machines, thereby improving sewing efficiency.

[0028] Furthermore, each lifting component 21 is detachably mounted on the base plate 2, and each lifting component 21 is arranged along the length of the sewing groove of the base plate. Specifically, the lifting component 21 is provided with a first magnetic component (not shown in the figure), and the base plate 2 is provided with a second magnetic component (not shown in the figure). The first magnetic component and the second magnetic component are matched and are magnets that can attract each other. Under the magnetic action of the magnets, the lifting component 21 can be easily installed onto the base plate 2, and the lifting component 21 can also be quickly positioned in a preset position. When the lifting component 21 is removed from the base plate 2, the operator can simply pry it off by hand, which is simple to operate and further improves the convenience of installation and removal.

[0029] Furthermore, the width of the receiving groove 32 is greater than the thickness of the raised part 21. The template 3 is provided with adjusting plates 33 at positions corresponding to the receiving groove 32 to adjust the width of the receiving groove 32. The adjusting plates 33 are arranged along the length of the receiving groove 32 and are detachably mounted on the template 3. Two adjusting plates 33 are symmetrically arranged opposite each other on the template 3. The two adjusting plates 33 can adjust the width of the receiving groove 32 to accommodate each raised part 21, allowing the fixture to adapt to the sewing of webbing on the heels of different shoe models; simultaneously, they clamp the raised part 21 to prevent the raised portion of the shoe heel 8 mounted on the raised part 21 from shaking.

[0030] Furthermore, the width of the template sewing groove 31 is 10mm-15mm.

[0031] The implementation principle of this utility model is as follows: First, the worker lifts the template 3 upward using the lifting mechanism 4. Then, the worker places the shoe heel 8 on the base plate 2 and adjusts the position of the shoe heel 8 so that the raised parts on both sides of the shoe heel 8 are placed on the two raised pieces 21, and the area for sewing the webbing 9 corresponds to the sewing groove of the base plate and the sewing groove 31 of the template. Then, the worker moves the template 3 downward using the lifting mechanism 4. After the template 3 moves downward, the two raised pieces 21 drive the raised parts on both sides of the shoe heel 8 to pass through the corresponding receiving positions. The shoe is placed in the groove 32, and then the width of the groove 32 is adjusted by the corresponding adjustment plate 33 so that the adjustment plate 33 presses the raised parts on both sides of the shoe heel 8. At this time, the arc of the upper surface of the raised part 21 supports the arc of the shoe heel 8. The adjustment plate 33 and the groove 32 restrict the movement of the shoe heel 8, thereby preventing the shoe heel 8 from wrinkling. At this time, the worker places the webbing 9 in the template sewing groove 31, and then the worker turns on the computer sewing machine so that the needle of the computer sewing machine sewn the webbing 9 onto the shoe heel 8.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
