Description
Technical Field
[0001] The utility model relates to the technical field of shoe upper processing, in particular to a shoe upper forming machine. Background Art
[0002] Shoes are items that protect the feet and increase the walking comfort of the feet. Shoes are generally composed of uppers and soles. The arched uppers and soles form a space for the feet to wear. In traditional technology, an upper forming machine generally uses an upper mold and a lower mold to jointly surround a forming cavity, and extrude the fabric to shape the fabric in the cavity to form the shape of the upper. However, when the upper mold and the lower mold are used to jointly surround the forming cavity and the upper is shaped by the cavity, a set of upper molds and lower molds can only process one type of upper. If different uppers need to be produced, multiple sets of upper molds and lower molds need to be configured, which increases the manufacturing cost of the upper.

The mounting plate 24 is slidably connected to the guide rod 21, and the limiting wall 30 and the contact component 40 are both connected to the mounting plate 24.
[0037] like Figure 2 As shown, the limiting wall 30 is connected to the lifting drive mechanism 20 and is provided with a processing space 31. Specifically, the limiting wall 30 includes a bottom wall 32 and a surrounding wall 33. The bottom wall 32 is connected to the limiting wall 30 of the lifting drive mechanism 20.

The surrounding wall 33 is arranged corresponding to the edge of the electric heating shoe last 60.
[0038] like Figure 2 As shown, the contact component 40 is arranged in the processing space 31, and the contact component 40 includes a fixed seat 41, a flexible pad 42 and a heat insulation layer. The fixed seat 41 is connected to the limiting wall 30 of the lifting drive mechanism 20.
