[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0024] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the present application provides a sole production mold, including an upper mold 1 and a lower mold 2. The upper mold 1 and the lower mold 2 are rotatably connected through a rotating shaft. When the upper mold 1 and the lower mold 2 are closed, a foaming cavity is formed between the upper mold 1 and the lower mold 2. By adding a foaming agent to the lower mold 2 when opening the mold, the foaming agent foams in the foaming cavity to form a foamed sole.

[0025] As Figure 2 , Figure 3 and Figure 4 shown, a movable mold 3 is slidably arranged on the upper mold 1. A guide rod 4 penetrating through the movable mold 3 is fixedly connected to the upper mold 1. A spring 5 is sleeved on the guide rod 4, and both ends of the spring 5 are connected to the upper mold 1 and the movable mold 3. Among them, the upper mold 1 is provided with a plurality of installation openings 6 penetrating through to the foaming cavity. The plurality of installation openings 6 are annularly arranged with the foaming cavity as the center. A cutting ring knife 7 is arranged in the foaming cavity. The cutting ring knife 7 is fixedly connected to the movable mold 3 through the installation openings 6. In the initial state, the spring 5 will push the movable mold 3, and the cutting ring knife 7 will, under the drive of the movable mold 3, keep blocking the installation openings 6, so that during the foaming process, the foaming agent will not overflow out of the foaming cavity through the installation openings 6.

[0026] As Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, a locking member is arranged between the movable mold 3 and the lower mold 2. The locking member includes a hook 8. One end of the hook 8 is rotatably arranged on the movable mold 3. A convex block 9 is formed on the lower mold 2. When the upper mold 1 and the lower mold 2 are closed, the other end of the hook 8 is hooked on the convex block 9. At this time, there is an included angle between the length direction of the hook 8 and the gravity direction, and the convex block 9 is located on the side of the hook 8 away from the ground. By using the pulling of the hook 8, relative rotation between the upper mold 1 and the lower mold 2 cannot be carried out, ensuring the stability during mold closing.

[0027] When the molding is completed and mold opening is required, a force is applied to the movable mold 3 to overcome the elastic force of the spring 5, causing the movable mold 3 to slide. The cutting ring knife 7 cuts the foamed sole, thereby trimming the overflow material and burrs of the sole, saving the subsequent trimming process and time, improving the processing efficiency. Relative sliding occurs between the hook 8 and the convex block 9, so that the hook 8 does not catch the convex block 9. At the same time, the hook 8 rotates due to its own gravity, making its length direction consistent with the gravity direction, disengaging from the convex block 9, and stopping applying force to the movable mold 3. The movable mold 3 resets due to the elastic force of the spring 5. At this time, the upper mold 1 can be directly rotated to achieve mold opening.

[0028] As Figure 3 and Figure 4 shown, stop blocks 10 are formed on both sides of the hook 8 corresponding to the movable mold 3. The stop blocks 10 are used to abut against the hook 8. A space for the hook 8 to rotate is formed between the two stop blocks 10. The two stop blocks 10 limit the rotation angle of the hook 8, so that when the mold is closed, the hook 8 approaches the convex block 9, facilitating the mold locking operation.

[0029] In summary, the mold provided in this embodiment trims the overflow material and burrs of the sole, saves the subsequent trimming process and time, and improves the processing efficiency.

[0030] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as within the protection scope of the present invention.
