[0008] The bottom wall of the positioning groove is further provided with a protruding positioning portion, and the vamp can be clamped and fixed with the positioning portion when the vamp is clamped into the positioning groove.

[0009] The height of the positioning portion is higher than the height of the vamp clamped into the positioning groove, so that a guide groove capable of moving the sewing positioning head of the sewing machine inside is formed between the side wall of the positioning portion and the guide surface.

[0010] The front and rear ends of the positioning portion are spaced apart from the front and rear of the guide surface, so as to form a space for the sewing positioning head of the sewing machine.

[0011] The positioning groove is designed to be larger at the front and smaller at the back.

[0012] The guide surface includes a first arc segment, a first circular segment and a second arc segment arranged symmetrically, and the first arc segment, the first circular segment and the second arc segment on the same side are connected to each other. A first transition segment is provided between two adjacent first arc segments and a second transition segment is provided between two adjacent second arc segments.

[0015] The first template is also provided with recessed holes that allow external moving structures to engage and position themselves.

[0016] Each of the aforementioned positioning posts has an arc-shaped top.

[0017] Compared with existing technologies, this utility model has the following advantages: When using this utility model, firstly, the shoe upper is aligned with the positioning groove on the first template, then the shoe upper is pressed down to engage with the positioning groove. Simultaneously, multiple positioning posts on the first template also engage with the through holes on the shoe upper. Next, the second template is placed over the first template, thus exposing the processing area through the groove. The forming mold is placed on the sewing machine table, and the first template is pushed so that its engaging part engages and is fixed with the external moving structure of the sewing machine. Simultaneously, the components on the external moving structure... Press down the first template to ensure that its upper end is positioned but can slide parallel to the sewing machine table. The operator pushes the left, right and lower sides of the forming mold with both hands and starts the sewing machine, causing the sewing positioning head to press down to the top of the shoe upper. The external moving structure moves along the preset trajectory, guiding the sewing machine to sew in the processing area. Due to the design of the guiding surface, this can ensure the accuracy of processing, improve the processing effect, and effectively reduce the generation of defective products. At the same time, the second template is also equipped with positioning holes for the positioning pins to be inserted, which can prevent the shoe upper from moving up and down and facilitate processing.
