[0018] By adopting the above technical solution, the shielding sheet main body, as the main part of the shielding sheet mechanism, can effectively shield the gap, prevent the injection molding material from penetrating, and ensure the appearance quality of the product.

[0019] Furthermore, four adhesive sheets are provided, and the four adhesive sheets are provided in a rectangular structure.

[0020] By adopting the above technical solution, providing four adhesive sheets can increase the adhesive area between the shielding sheet body and the outer template and the sliding plate, providing stronger adhesion.

[0021] Furthermore, chamfers are provided on both sides of the shielding piece body.

[0022] By adopting the above technical solution, the chamfers on both sides of the shielding sheet body can make the shielding sheet fit the shape of the mold more closely, avoiding the problem of warping or failure to conform to the curvature of the mold caused by the right-angle edge.

[0023] Furthermore, the shielding piece body is an arc-shaped structure.

[0035] The following describes an embodiment of the utility model based on its overall structure.

[0036] Embodiment 1:

[0037] A retractable sole mold, such as Figure 1-Figure 4 As shown, it includes a first half shell 1, a sliding groove 2 is provided on the first half shell 1, a second half shell 3 is provided on one side of the first half shell 1, and both sides of the first half shell 1 and the second half shell 3 are fixedly connected with an adjustment mechanism 5, the adjustment mechanism 5 includes a fixed block 501, the internal thread of the fixed block 501 is connected with a shaping threaded rod 502, one end of the shaping threaded rod 502 is fixedly connected with a limiting plate 503, the inner part of the limiting plate 503 is clamped with a ball rod 504, one end of the ball rod 504 is fixedly connected with an outer template 505, the inner part of the outer template 505 The outer mold 505 is slidably connected to the outer mold 505, and the sliding plate 506 is rotatably connected to the adjacent outer mold 505.

The sliding plate 506 ensures a flexible connection between adjacent outer molds 505, making the entire adjustment process smoother and more stable. At the same time, the retractable sole mold design makes the length and shape of the sole adjustable, so that soles of different lengths and shapes can be produced, which greatly improves the flexibility and applicability of the mold.

[0038] See also Figure 1 and Figure 2 A support plate 4 is fixedly connected to the top of the second half shell 3, and the support plate 4 is slidably connected to the sliding groove 2. The support plate 4 enables the bottom of the mold to maintain a continuous structure, so that when the sole is produced, the bottom can maintain a specified plane without forming a depression at the bottom. At the same time, the design of the support plate 4 enhances the structural stability of the mold. It is slidably connected to the first half shell 1 through the sliding groove 2, so that the second half shell 3 can remain stable during the movement and is not prone to deviation or shaking.

[0039] See also Figure 1 and Figure 2 The bottom of the first half shell 1 is fixedly connected with a mounting block 6, and the inside of the mounting block 6 is rotatably connected with a telescopic threaded rod 7. The mounting block 6 provides a stable mounting base for the telescopic threaded rod 7, ensuring the stability and reliability of the threaded rod, so that the telescopic threaded rod 7 can rotate smoothly inside. At the same time, the rotatable connection between the telescopic threaded rod 7 and the mounting block 6 enables the threaded rod to be easily rotated when needed, thereby conveniently and quickly adjusting the length of the mold, improving the adjustment efficiency of the mold, and increasing the flexibility and practicality of the mold.

[0040] See also Figure 1 and Figure 2 A threaded block 8 is fixedly connected to the bottom of the second half shell 3, and the threaded block 8 is threadedly connected to the telescopic threaded rod 7.
