[0038] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and understand the present invention and are not intended to limit the present invention.

[0039] This embodiment discloses a toe shaping machine, comprising a frame 1, at least one shaping mechanism 2 mounted on the frame 1, and at least one shaping mold 3 used in conjunction with the shaping mechanism 2. Figure 1 As shown, in this embodiment, two forming mechanisms 2 are assembled side by side on the frame 1, and two sets of forming molds 3 are correspondingly configured. During production operations, workers can alternately operate the two forming mechanisms 2 to fully utilize the waiting time for the toe to be formed, thereby improving production efficiency.

[0040] First, the shaping die 3 is described. Figure 6 As shown, the shaping mold 3 comprises a first mold 4 and a second mold 5. The first mold 4 has a toe placement slot with a side opening, while the second mold 5 is a metal plate shaped to match the opening of the toe placement slot. The second mold 5 seals the opening of the toe placement slot of the first mold 4, forming a shaping cavity 6 for the toe. In this embodiment, aluminum is selected to fabricate the first and second molds 4 and 5, taking into account thermal conductivity, economic performance, and overall quality.

[0041] In addition, in order to facilitate the removal of the shaping mold 3, a handle 7 is provided on the upper surface of the first mold 4. Figure 6 As shown, the handle 7 in this embodiment is a bolt threadedly assembled on the upper surface of the first mold 4.

[0042] Typically, one molding die 3 is used to mold the toes of two shoe sizes of the same shoe type. Therefore, the term "a set of molding die 3" refers to multiple molding die 3 with identical structures but different sizes. For example, a set of four molding die 3 for men's leather shoes typically corresponds to standard sizes 38 and 39, 40 and 41, 42 and 43, and 44.

[0043] The shaping mechanism 2 is further described. Figure 1 and Figure 2As shown, the shaping mechanism 2 includes a mold placement groove 8, an electric heating plate 9, a mold horizontal push assembly 10, and a mold pressing assembly 11. The mold placement groove 8 is enclosed by steel plates, and its bottom is bolted to the work surface of the frame 1 to accommodate the aforementioned shaping mold 3. The electric heating plate 9 adopts an existing structure and is fixed to the bottom of the mold placement groove 8 to heat the shaping mold 3 placed in the mold placement groove 8.

[0044] The mold horizontal push assembly 10 is assembled on one side of the mold placement groove 8 and is used to apply horizontal force to the shaping mold 3 placed in the mold placement groove 8 to push the second mold 5 closer to the first mold 4 and squeeze the shoe head in the shaping cavity 6. Figure 4 and Figure 5 As shown, the mold horizontal pushing assembly 10 includes a mounting plate 12 and a first linear drive 13, wherein the mounting plate 12 is assembled on one side plate of the above-mentioned mold placement groove 8 through a plurality of bolts and nuts, and the first linear drive 13 is fixed on the mounting plate 12.

[0045] Furthermore, the side plate on the mold placement groove 8 for fixing with the mounting plate 12 has a through hole at its center. The output end of the first linear actuator 13 can pass through the through hole to contact the outer wall of the second mold 5 placed in the mold placement groove 8. It should be noted here that when the shaping mold 3 is placed in the mold placement groove 8, the second mold 5 needs to be oriented toward the mold horizontal push assembly 10. Specifically, Figure 4 shown.

[0046] The mold pressing assembly 11 is assembled on the frame 1, with the working end facing downward toward the mold placement groove 8, and is used to apply longitudinal force to the heel of the shoe placed on the shaping mold 3 in the mold placement groove 8, so as to push the shoe so that the toe is completely squeezed into the shaping cavity 6 of the shaping mold 3. Figure 3 As shown, the shoe pressing assembly includes a second linear drive 14 fixed on the frame 1 and a pressing plate 15 assembled at the output end of the second linear drive 14 .

[0047] Furthermore, the lower pressing plate 15 is suspended directly above the mold placement groove 8, and a concave block 16 is fixedly provided on the bottom surface of the lower pressing plate 15 facing the mold placement groove 8. A rubber pad 17 for contacting the heel of the shoe is fixedly provided in the groove of the concave block 16. In this embodiment, a guide column 18 is further provided between the lower pressing plate 15 and the second linear actuator 14 to enable the lower pressing plate 15 to be raised and lowered vertically. Figure 3 As shown, in this embodiment, two guide posts 18 are provided, one on each side of the output end of the second linear actuator 14. It should be noted that a connecting plate 19 is provided at the bottom of the second linear actuator 14 in this embodiment. The connecting plate 19 has a through hole formed on each side of the output end of the second linear actuator 14. The guide posts 18 are inserted into the through holes and their bottom ends are fixedly connected to the lower pressure plate 15.

[0048] In this embodiment, the first linear actuator 13 and the second linear actuator 14 are both cylinders in the prior art. Of course, oil cylinders, linear motors or electric push rods can also be used according to actual conditions.

[0049] In order to facilitate the operation of workers, this embodiment further provides an operating table 20 on one side of the frame 1 for temporarily placing the shaping mold 3, shoes or other components.

[0050] When using this embodiment, first place the shaping mold 3 into the mold placement groove 8, and set the working temperature of the electric heating plate 9 to 100°C; then insert the toe of the shoe to be shaped into the shaping cavity 6 of the shaping mold 3, as shown in FIG. Figure 1 Next, the shaping mechanism 2 is activated, causing the second linear actuator 14 to apply downward force to the shoe, pushing the shoe's toe completely into the shaping cavity 6. The first linear actuator 13 then pushes the second mold 5 toward the first mold 4, squeezing the shoe's toe within the shaping cavity 6 and heat-setting it. Finally, the first and second linear actuators 13 and 14 are controlled to return to their original positions, and the shoe is removed.

[0051] It takes several minutes to wait from starting the shaping mechanism 2 to completing the toe shaping. During this period, another shaping mechanism 2 can be operated to shape the toe of another shoe to be shaped.

[0052] It should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art may still modify the technical solutions described in the above embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
