[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

Figure 2 This is a schematic diagram of the molding assembly in this utility model. Figure 3 This is a cross-sectional view of the molding assembly in this utility model. Figure 4 This is a schematic diagram of the U-shaped bracket in this utility model. Figure 5This is a schematic diagram of the lower mold assembly of this utility model. The shoe sole forming device includes: a base 1 and one or more forming mechanisms 2 disposed on the base 1; each forming mechanism 2 includes: a pressing mold assembly 21 and a lifting cylinder 22. The lifting cylinder 22 is located at the bottom of the pressing mold assembly 21, and the output end of the lifting cylinder 22 is connected to the pressing mold assembly 21. The pressing mold assembly 21 is driven by the lifting cylinder 22 to move in the vertical direction. The pressing mold assembly 21 includes: a connecting arm 211, a rotating motor 212, and a mold frame 213. The mold frame 213 is provided with multiple upper mold assemblies 214. The rotating motor 212 is rotatably connected to the connecting arm 211, and the mold frame 213 is sleeved on the rotating motor 212. The mold frame 213 is driven by the rotating motor 212 to rotate. The lifting cylinder 22 is used to move the pressing mold assembly 21 in the vertical direction to adjust the position of the pressing mold assembly 21 for the next operation. The pressing mold assembly 21 is used to press and form the shoe sole.

[0031] In this embodiment, the base 1 is provided with two forming mechanisms 2. The number of forming mechanisms 2 can be adjusted according to the actual situation to adapt to production efficiency. The mold frame 213 is provided with two upper mold assemblies 214. The number of upper mold assemblies 214 can also be adjusted to four according to the actual situation to adapt to production efficiency.

[0032] Furthermore, the output end of the rotary motor 212 is provided with a rotating mechanism 24. The rotary motor 212 is rotatably connected to the connecting arm 211 based on the rotating mechanism 24, and the rotating mechanism 24 is fixedly connected to the connecting arm 211. The rotating mechanism 24 is rotatably connected to the rotary motor 212. The rotating mechanism 24 includes a fixing part and a bearing. One side of the fixing part is fixedly connected to the connecting part, and the other side of the fixing part is fixedly connected to the output end of the rotary motor 212. The output end of the rotary motor 212 is fitted with a bearing. When the rotary motor 212 starts to rotate, because the output end of the rotary motor 212 is fixedly connected to the connecting arm 211 and the connecting arm 211 cannot rotate, the rotary motor 212 rotates, thereby driving the entire mold frame 213 to rotate. This facilitates the rotation of multiple mold components on the mold frame 213 to corresponding angles, allowing different upper mold components 214 to perform molding operations, reducing the steps of replacing the entire upper mold component 214, saving time from frequent mold changes, and improving the working efficiency of the two-color shoe sole forming device.

[0033] Furthermore, each of the upper mold components 214 includes an upper mold 2141 and a mounting bracket 2142. The upper mold 2141 is detachably mounted on the mounting bracket 2142, which is fixedly connected to the rotary motor 212. When the rotary motor 212 rotates, it drives the mounting bracket 2142 to rotate, causing multiple upper mold components 214 to switch under the drive of the rotary motor 212. That is, driven by the rotary motor 212, one upper mold component 214 can switch to another upper mold component 214 for molding operations. In this embodiment, the upper mold 2141 is detachably mounted on the mounting bracket 2142 by screws, which facilitates flexible configuration and adjustment of the upper mold 2141 in different positions and allows for quick disassembly and replacement of different shoe sole molds, saving time spent on frequent mold changes and effectively improving work efficiency.

[0034] Furthermore, a heating rod 2143 is provided inside the mounting bracket 2142, and the heating rod 2143 is evenly distributed within the mounting bracket 2142. The heating rod 2143 is used to dissipate heat, thereby heating the upper mold 2141, so that the upper mold 2141 has a certain temperature so that the material can be pressed into the corresponding shape during molding. The even distribution of the heating rod 2143 within the mounting bracket 2142 allows the mounting bracket 2142 to quickly transfer heat to the upper mold 2141, and ensures that the upper mold 2141 is heated evenly. This ensures that the material is heated evenly during molding, and can be quickly formed according to the shape of the mold, thereby improving molding quality and efficiency.

[0035] Furthermore, a heat insulation layer is provided on the side of the mounting bracket 2142 near the rotating motor 212. The heat insulation layer is used to reduce heat transfer. In this embodiment, when the heating rod 2143 starts working, the heat of the heating rod 2143 is transferred to the mounting bracket 2142, and then to the rotating motor 212 through the mounting bracket 2142, causing the rotating motor 212 to become too hot. The heat insulation layer can effectively reduce the heat transferred from the heating rod 2143 to the rotating motor 212 through the mounting bracket 2142, thereby reducing the heat of the rotating motor 212 and lowering the risk of the rotating motor 212 failing due to excessive heat. This helps to ensure the performance of the rotating motor 212 and extend its service life.

[0036] Furthermore, each molding mechanism 2 also includes a U-shaped bracket 23 with a J-shaped guide rail 231. The molding assembly 21 is embedded in the J-shaped guide rail 231. The U-shaped bracket 23 supports the molding assembly 21, and the J-shaped guide rail 231 changes the position of the molding assembly 21. When the molding assembly 21 moves to the top of the J-shaped guide rail, the connecting arm 211 in the molding assembly 21 points obliquely upward, so that the mold frame 213 and the rotating motor 212 also point obliquely upward. This reduces the contact area between the molding assembly 21 and the base 1, preventing the molding assembly 21 from colliding with the base 1 when the molding assembly 211 is switched to the mold assembly 214 at a position parallel to the base 1. This reduces the risk of mold damage due to collision between the molding assembly 21 and the base 1, improves the integrity of the molding assembly 21, and enhances the molding quality of the two-color sole molding device.

[0037] Furthermore, the connecting arm 211 is equipped with rollers 2111, and the connecting arm 211 is embedded in the J-shaped guide rail 231 based on the rollers 2111. The connecting arm 211 is driven by the driving cylinder to move on the J-shaped guide rail 231. The rolling friction of the rollers 2111 has lower resistance than sliding friction, which allows the connecting arm 211 to move faster, thereby improving motion efficiency. Especially during molding, where frequent movement is required, this significantly reduces energy consumption and time costs. Secondly, the rollers 2111 ensure that the connecting arm 211 moves stably within the track, reducing safety risks caused by shaking or vibration, which helps to improve the stability and safety of the molding assembly 21 and ensures smooth operation.

[0038] Furthermore, the U-shaped bracket 23 has one or more support plates 232, each of which has multiple circular holes. In this embodiment, the U-shaped bracket 23 has two support plates 232, which are used to support the stability of the U-shaped bracket 23 and improve its load-bearing capacity. Each support plate 232 has five circular holes, which are used to disperse the stress inside the U-shaped bracket 23, preventing stress concentration that could lead to deformation or breakage. Simultaneously, the multiple circular holes can also serve as weight-reduction holes, removing material from low-stress areas during loading, thereby reducing the weight of the U-shaped bracket 23.

[0039] Furthermore, the base 1 is detachably equipped with the same number of lower mold assemblies 4 as the molding mechanism 2, that is, two lower mold assemblies 4 are detachably configured on the base 1. The lower mold assemblies 4 are located below the molding mechanism 2, and correspond to the upper mold assembly 214. The upper mold assembly 214 is driven by a driving cylinder to move to the lower mold assembly 4 and press against the lower mold assembly 4, so that the material inside the lower mold assembly 4 is formed into the shoe sole. The lower mold 41 is detachably installed under the mounting bracket 2142 by screws, which facilitates the flexible configuration and adjustment of the lower mold 41 in different positions, and allows for quick disassembly and replacement of different shoe sole molds, saving time from frequent mold changes and effectively improving work efficiency.

[0040] Furthermore, the lower mold assembly 4 includes a lower mold 41 and a plurality of fixing blocks 42, which are distributed around the lower mold 41. In this embodiment, the lower mold assembly 4 includes four fixing blocks 42, which are used to fix the lower mold 41 in corresponding positions. Two fixing blocks 42 are located on both sides of the lower mold 41, and the remaining two fixing blocks 42 are located on the other side of the lower mold 41. This restricts the movement range of the lower mold 41 from three directions, preventing the fixing blocks 42 from shifting after the molding operation. This helps reduce the risk of the fixed lower mold 41 moving due to external forces or vibrations, thereby maintaining the working stability of the two-color sole forming device.

[0041] The working principle of this utility model:

[0042] The lifting cylinder 22 drives its corresponding pressing mold assembly 21 to move downward along the J-shaped guide rail 231, so that the upper mold assembly 214 on the mold frame 213 presses into the corresponding lower mold assembly 4, so that the material in the lower mold 41 forms the first color sole. Then, the lifting gun barrel drives the corresponding pressing mold assembly to move upward along the J-shaped guide rail 231 until the pressing mold assembly 21 moves to the top. The rotating motor 212 rotates the mold frame 213, so that the upper mold 2141 on the mold frame 213 rotates 180° and switches to another upper mold 2141. Then, the lifting cylinder 22 drives its corresponding pressing mold assembly 21 to move downward along the J-shaped guide rail 231, so that the upper mold assembly 214 on the mold frame 213 presses into the corresponding lower mold assembly 4, so that the material in the lower mold 41 forms the second color sole.

[0043] In summary, this invention, by incorporating a lifting cylinder that drives the pressing mold assembly to move vertically, ensures sufficient kinetic energy for downward pressing and forming of the shoe sole, thereby improving the quality of the produced product. Furthermore, by using a pressing mold assembly and a rotating motor to drive the mold frame, multiple upper mold assemblies can be switched under the motor's drive. This allows for flexible configuration and adjustment of the upper molds in different positions and enables quick disassembly and replacement of different shoe sole molds, saving time spent on frequent mold changes and effectively improving work efficiency.

[0044] Furthermore, the above description provides a detailed introduction to a two-color shoe sole forming device provided by the embodiments of this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
