[0002] The mold for forming the inner core of the shoe sole typically includes key components such as an upper mold, a bottom mold (lower mold), and the inner core body. The key parts of the upper mold and the bottom mold are the shape and size of the mold cavity, which together constitute the space for forming the inner core of the shoe sole. The inner core body is placed in the mold cavity and is the direct carrier for forming the inner core of the shoe sole.

[0003] In the existing technology, due to the influence of factors such as mold material and molding process parameters (such as temperature, pressure, and time), the shoe material and the inner surface will form a tight bond, which makes it difficult for the shoe to be completely demolded from the inner surface after molding, affecting production efficiency and product quality.

[0004] Therefore, existing molding dies have the problem of being too tightly fitted and inconvenient to demold during use. Utility Model Content

[0005] To overcome the problem of tight fit and inconvenience in demolding in existing molding dies, a molding die for the inner core of the shoe sole pull rod is proposed.

[0017] Please see Figures 1-6 This utility model provides an embodiment of a shoe sole pull rod inner core forming mold, including a lower mold 1, a pull rod 106, and a fixing member 5. An upper mold 2 is movably disposed at the upper end of the lower mold 1. Two bottom molds 101 are formed at the upper end of the lower mold 1. A flow groove 103 is formed at the upper end of the lower mold 1, and the two bottom molds 101 are interconnected through the flow groove 103. An insertion groove 104 is formed at the right end of the inner wall of the flow groove 103, and a sliding groove 105 is formed through the left end of the flow groove 103. The pull rod 106 is slidably disposed in the sliding groove 105. The fixing member 5 is formed through the left end of the lower mold 1, and the pull rod 106 is slidably disposed in the fixing member 5. The grooves of the sliding groove 105 and the insertion groove 104 are... The mold is circular with collinear axes. An intermediate mold 3 is set inside the bottom mold 101. An installation part 4 is rotatably set on the upper right end of the intermediate mold 3. The installation part 4 is equipped with a perforated inclined block 401 that limits the rotation angle of the intermediate mold 3. After molding is completed, the pulling rod 106 is pushed so that its right end carries the filling material in the flow groove 103 and inserts it into the insertion groove 104. When the upper mold 2 and the intermediate mold 3 move upward, the material on the bottom mold 101 expands and moves upward with the intermediate mold 3, but is dragged by the structure of the insertion groove 104. At the same time, the intermediate mold 3 rotates downward at a small angle with the help of the perforated inclined block 401. This series of operations solves the problem that the shoe is difficult to completely demold from the inner intermediate mold 3 after molding, and realizes the smooth demolding of the shoe.

[0018] Please see Figures 1-4 In this embodiment, a retaining sleeve 504 is fixedly connected to the left end of the fixing member 5, a retaining ring 107 is fixedly connected to the outer wall of the pulling rod 106, a spring 505 is fixedly connected to the right end of the retaining ring 107, and the other end of the spring 505 is fixedly connected to the left end of the fixing member 5. A first groove 501 and a second groove 502 are formed on the inner wall of the fixing member 5. A stop block 503 is fixedly connected to the outer wall of the pulling rod 106. The stop block 503 is adapted to the protruding grooves of the first groove 501 and the second groove 502. The arc-shaped outer wall of the retaining ring 107 is connected to the retaining sleeve. The arc-shaped inner walls of 504 fit together. The sleeve 504 is used to install the spring 505. The structure of the first groove 501 and the second groove 502 limits and fixes the pull rod 106. The upper end of the lower mold 1 has two positioning holes 102 for positioning. The lower end of the upper mold 2 is fixed with two positioning pins 202. The positioning pins 202 and the positioning holes 102 correspond to each other and are compatible. The lower end of the upper mold 2 has an upper mold groove 201. The intermediate mold 3 is placed between the upper mold groove 201 and the bottom mold 101.

[0019] Please see Figures 5-6In this embodiment, the upper end of the intermediate mold 3 is provided with a groove 301, and the inner wall of the groove 301 is fixedly connected to the front and rear ends of the fixed post 302. The perforated inclined block 401 is rotatably set on the fixed post 302. The left end section of the perforated inclined block 401 gradually shrinks to the right from top to bottom, which can restrict the upward angle rotation of the intermediate mold 3. When the intermediate mold 3 rotates upward, it will be limited by the left end protrusion of the perforated inclined block 401, but it can rotate downward at a small angle, thereby facilitating the quick demolding of the molded shoes on the intermediate mold 3.

[0020] First, a release agent is sprayed onto the surfaces of the bottom mold 101, the upper mold groove 201, and the intermediate mold 3. Then, the material is placed on the bottom mold 101 and the flow groove 103. Next, an external device drives the upper mold 2 and the intermediate mold 3 to move downwards to perform mold forming. After the shoe is formed, by pushing the pull rod 106 to the right, the stop block 503 slides along the second groove 502 to the first groove 501, and then rotates the pull rod 106, so that the left end of the stop block 503 and the left end of the inner wall of the first groove 501 fit together. At the same time, the retaining ring 107 is displaced by the reverse force of the spring 505, thereby moving the stop block 503. Fixed in the first groove 501, the right end of the pull rod 106 in the flow groove 103 carries the filling material in the flow groove 103 and inserts it into the insertion groove 104. When the upper mold 2 and the intermediate mold 3 move upward, the material on the bottom mold 101 expands instantly and moves upward with the intermediate mold 3. However, after being carried by the pull rod 106, it is inserted into the insertion groove 104, causing the molded shoe to be dragged downward by the insertion groove 104. At this time, the intermediate mold 3 can be rotated downward at a small angle by the slope of the perforated inclined block 401, so that the shoe on the intermediate mold 3 can be completely demolded.
