Detailed Implementation

[0022] The following is in conjunction with the appendix Figure 1-6 The present invention will be further described in detail below:

[0023] This utility model embodiment discloses a high-top workwear rain boot mold, such as Figure 1 , Figure 2 , Figure 3 As shown, the system includes a top mold 2 and a bottom mold 3. The bottom mold 3 is located below the top mold 2. Shoe body cavities 9 are formed on the opposite sidewalls of the top mold 2 and the bottom mold 3. A rain boot core 5 is provided between the bottom mold 3 and the top mold 2. The rain boot core 5 is rotatably connected to the bottom mold 3. A first connecting rod 7 is rotatably connected to the sidewall of the rain boot core 5 via a pivot. A second connecting rod 8 is rotatably connected to the first connecting rod 7. The second connecting rod 8 is rotatably connected to the top mold 2 via a pivot. An inner lining clamping assembly is provided on the sidewall of the rain boot core 5. A sole assembly is provided inside the bottom mold 3. A waste discharge assembly is provided on the sidewall of the bottom mold 3. In this embodiment, by adding the inner lining clamping assembly, the system achieves the desired effect. The lining of the rain boot fits more tightly to the rain boot core 5 and limits the edge of the lining, making the edge less prone to wrinkling or curling, and preventing the rain boot lining from being missing or wrinkled, thereby improving wearing comfort. Through the sole component, the rain boot cavity 14 or sole cavity 6 can be switched by rotation, so that the rain boot is molded in one piece, ensuring a tight bond between the rain boot and the sole, and enhancing the overall durability of the product. In addition, through the waste discharge component, excess waste generated at the unloading port during the production process can be cleaned up in a timely manner, reducing manual labor intensity, while also ensuring the cleanliness of the mold and extending the service life of the mold.

[0024] like Figure 1 , Figure 2 , Figure 6 As shown, the clamping assembly includes a limiting connecting block 15 and a clamping block 16. Two limiting connecting blocks 15 are rotatably connected to the side wall of the rain boot core 5 via a rotating shaft. The limiting connecting blocks 15 are respectively disposed on both sides of the rain boot core 5. The clamping block 16 is integrally formed on the two limiting connecting blocks 15. The clamping block 16 is tightly fitted to the rain boot core 5. In this embodiment, by adding the limiting connecting blocks 15, the limiting connecting blocks 15 can rotate, causing the clamping block 16 to fit tightly against the rain boot lining, thereby making the edges less prone to wrinkling or curling, and preventing the rain boot lining from being missing or wrinkled, thus improving the comfort of wearing.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the sole assembly includes a sole mold 1, a rain boot cavity 14, a sole cavity 6, a second cylinder 12, and an injection hole 13. The second cylinder 12 is fixedly connected to the inside of the upper mold 3 by bolts. The output end of the second cylinder 12 passes through the upper mold 3 and is rotatably connected to the sole mold 1. The side wall of the sole mold 1 has the rain boot cavity 14 and the sole cavity 6. The side walls of the rain boot cavity 14 and the sole cavity 6 have the injection hole 13. In this embodiment, by adding the second cylinder 12, the longitudinal displacement of the sole mold 1 is achieved, thereby allowing the rain boot cavity 14 or the sole cavity 6 to rotate and switch with the upper mold 3 and the upper mold 2, thus completing the integrated injection molding of the upper and sole of the rain boot.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, the waste discharge assembly includes a first cylinder 4, a lifting rod 10, and a pusher rod 11. The side walls of the shoe sole mold 3 are bolted to the first cylinder 4. The output ends of the two first cylinders 4 are welded with lifting rods 10. The side walls of the lifting rods 10 are welded with pusher rods 11 that cooperate with the injection holes 13. In this embodiment, by adding the first cylinder 4, the output end of the first cylinder 4 drives the lifting rod 10, thereby driving the pusher rod 11 to move longitudinally. When the second cylinder 12 is activated, the injection holes 13 on the shoe sole mold 1 and the pusher rod 11 come into close contact, and the waste in the injection holes 13 is discharged, thereby completing the cleaning of the waste in the injection holes 13.

[0027] like Figure 1 , Figure 2 , Figure 5 As shown, both the top mold 2 and the bottom mold 3 of the shoe body are provided with rain boot cavities 14. The rain boot core 5, the rain boot cavity 14, and the sole cavity 6 are symmetrically arranged along the center line. In this embodiment, by arranging them along the center line, multiple rain boot cores 5, rain boot cavities 14, and sole cavities 6 can be produced simultaneously.

[0028] like Figure 5 As shown, the push rod 11 and injection hole 13 are arranged in a longitudinal array. The number of push rods 11 and injection holes 13 in the longitudinal direction is N, where N≥2. In this embodiment, by increasing the number of push rods 11 and injection holes 13, the push rods 11 and injection holes 13 are made to cooperate with each other.

[0029] The implementation principle of this utility model embodiment is as follows:

[0030] In use, the operator first puts the rain boot liner on the rain boot core 5 and rotates the limiting connecting block 15 to drive the clamping block 16 to fit tightly against the rain boot liner. Then, the shoe body top mold 2 and shoe body bottom mold 3 are pressed together. The second cylinder 12 is then started, so that the output end of the second cylinder 12 drives the shoe bottom mold 1, thereby causing the shoe bottom mold 1 to drive the rain boot cavity 14 to fit close to the shoe body top mold 2 and shoe body bottom mold 3. Then, the shoe body is injection molded through the injection hole 13.

[0031] Secondly, by rotating the sole mold 1, the sole mold 1 causes the sole cavity 6 to move closer to the top mold 2 and bottom mold 3 of the shoe body, thereby causing the sole cavity 6 to rotate to be close to the top mold 2 and bottom mold 3 of the shoe body, and then the sole and shoe body are integrally injection molded through the injection hole 13.

[0032] Finally, by activating the first cylinder 4, the output end of the first cylinder 4 drives the lifting rod 10, thereby driving the push rod 11 to move longitudinally. Then, by activating the second cylinder 12, the injection hole 13 on the shoe sole mold 1 and the push rod 11 come into close contact, and the waste material in the injection hole 13 is discharged, thus completing the cleaning of the waste material in the injection hole 13.
