[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0020] Please refer to Figure 1-4 ;
[0021] The utility model aims to design a shoe last with two usage modes, which can be switched according to actual needs. Taking casual shoes as an example, in addition to common shoes on the market, a kind of shoes that do not need to tie shoelaces and can be worn with the help of hands has also emerged, and people can directly wear them. This kind of shoes has a common feature that the position of the upper heel 41 is particularly hard, which can avoid the deformation of the upper heel 41 when wearing, and the upper edge 42 of the heel is inclined to extend outward, which is also particularly hard, so that the foot can be introduced into it without deformation. During the manufacturing process, it is necessary to put a shoe last in the upper heel 41 and the upper edge 42 respectively, and after hot pressing and forming, the upper heel 41 and the upper edge 42 will become very hard and will not be deformed, but there is an inclination angle between the heel 41 and the upper edge 42 of the upper, so ordinary shoe lasts cannot do it and need to be remade; in order to not increase the cost, a combination module 21 combined with the ordinary shoe last is set to reduce the production cost; specifically, it includes a shoe last body 11 and a combination module 21, the combination module 21 can be detachably placed on the surface of the last opening 12 of the shoe last body 11, and the combination module 21 protrudes laterally from the last opening 12, so that it forms an angle 3 of 80° to 120° with the heel position of the shoe last body 11; different combination modules 21 can be selected according to the type of shoes to form different angles 3.
[0022] Place the heels of the folded uppers waiting for hot pressing on the last body 11, so that the heels 41 of the uppers are in contact with the last body 11, and the upper edge 42 is in contact with the bottom surface of the combination module 21, and then use hot pressing to harden the heels 41 and the upper edge 42 of the uppers to complete the production. When ordinary shoes need to be produced, it is only necessary to remove the combination module 21 from the last body 11. In other words, two types of shoes can be produced by combining or disassembling the combination module 21 on the basis of ordinary shoe lasts. There is no need to modify the last body 11 or customize the shoe lasts, which can reduce production costs.
[0023] Furthermore, a soft convex strip can be provided between the heel 41 and the upper edge 42 of the upper to resist the heel from falling off. When placed, the soft convex strip is placed at the corner of the last body 11 and the combination module 21 to play a fixing role and avoid displacement during hot pressing.
[0024] In the embodiment of the utility model, the bottom surface of the combined module 21 is not only inclined upward, but also has an arc surface design along the plane direction, so that the upper edge 42 is also arc-shaped after molding to adapt to the opening of the shoe.
[0025] The present utility model is directed to the connection relationship between the combination module 21 and the shoe last body 11. In one embodiment, a card slot 22 is provided on one side of the combination module 21. The card slot 22 is adapted to the rear side of the root of the shoe last body 11. When in use, the card slot 22 is aligned with one side of the shoe last opening 12 to achieve the fit. Preferably, one side of the shoe last opening 12 is an elliptical arc surface, and the corresponding card slot 22 is an elliptical slot position. Therefore, the card slot 22 also has a positioning function.
[0026] After the combined module 21 and the shoe last body 11 are combined, they can be fixed by means of screws or the like. When the combined module 21 is not needed, the lock between the combined module 21 and the shoe last body 11 is released, and the combined module 21 can be taken out of the shoe last body 11.
[0027] In another embodiment, the front end of the combination module 21 is rotatably connected to the last opening 12. When the combination module 21 is needed, the combination module 21 is rotated to make one side of the last opening 12 embed into the slot 22, and then it is fixed and locked with bolts. When it is not needed, the lock is released and the combination module 21 is rotated again to restore the last body 11 to its normal state for the production of ordinary shoes. Combining the last body 11 with the organization module can avoid loss, and the one-to-one pairing method is more standardized.
[0028] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
