[0043] The present invention will now be described in further detail with reference to the accompanying drawings.

[0044] like Figure 3As shown below, the structure and function of a shoe sole material will be described in detail.

[0045] A shoe sole material includes a bottom layer 11 and a contact layer 13, with an elastic layer 12 disposed between the bottom layer 11 and the contact layer 13. The bottom layer 11 is a rigid material, the elastic layer 12 is a shock-absorbing material, and the contact layer 13 is a flexible material.

[0046] The rigid material is rigid rubber, the shock-absorbing material is silicone rubber, and the flexible material is silicone.

[0047] The bottom layer 11 is in contact with the ground and is responsible for supporting the shoe. The elastic layer 12 mainly serves as shock absorption to improve comfort. The contact layer 13 is in contact with the foot, thereby improving comfort.

[0048] like Figures 1 to 2 As shown below, the steps and functions of a shoe sole material manufacturing process will be explained in detail.

[0049] A process for preparing shoe sole material, the process comprising the following steps:

[0050] S1: Insert the bottom mold 42 into the bottom of the forming groove 32;

[0051] S2: The injection mold 53 is inserted into the molding groove 32 on the molding mold 31, and the injection mold 53 injects the materials of the bottom layer 11, the elastic layer 12 and the contact layer 13 into the bottom mold 42 in sequence;

[0053] S4: An ultrasonic generator 34 is provided on the side of the molding die 31;

[0054] S5: When the elastic layer 12 is injected into the upper side of the bottom layer 11, the ultrasonic generator 34 generates ultrasonic waves that pass through the contact surface between the elastic layer 12 and the bottom layer 11, forming a corrugated contact surface between the elastic layer 12 and the bottom layer 11.

[0055] S6: When the contact layer 13 is injected onto the upper side of the elastic layer 12, the ultrasonic generator 34 generates ultrasonic waves that pass through the contact surface between the contact layer 13 and the elastic layer 12, forming a corrugated contact surface between the contact layer 13 and the elastic layer 12.

[0056] like Figures 4 to 12 As shown, in order to facilitate the implementation of a shoe sole material preparation process, a shoe sole material preparation device is designed. The structure and function of the shoe sole material preparation device are described in detail below.

[0057] A shoe sole material preparation device includes a device support 21, a lead screw 22 rotatably connected to the device support 21, a molding die 31 fixedly connected to the device support 21, and a molding groove 32 provided on the molding die 31.

[0058] A power mechanism I for driving the lead screw 22 to rotate is fixedly connected to the device bracket 21. The power mechanism I is preferably a servo motor.

[0059] A rotating ring 33 is rotatably connected to the molding die 31, and an ultrasonic generator 34 is provided on the rotating ring 33;

[0060] A power mechanism II for driving the rotating ring 33 to rotate is fixedly connected to the molding die 31. The power mechanism II is preferably a servo motor.

[0061] A telescopic mechanism I 41 is fixedly connected to the device bracket 21. A bottom mold 42 is fixedly connected to the telescopic end of the telescopic mechanism I 41. The bottom mold 42 can be inserted into the forming groove 32.

[0062] A telescopic mechanism II 51 is slidably connected to the device bracket 21. The telescopic mechanism II 51 is threadedly connected to the lead screw 22. An injection pipe 52 is fixedly connected to the telescopic end of the telescopic mechanism II 51. An injection mold 53 is fixedly connected to the injection pipe 52. The injection mold 53 has a hollow interior and multiple injection holes. All injection holes communicate with the interior of the injection mold 53. The injection pipe 52 communicates with the interior of the injection mold 53.

[0063] A support plate 54 is fixedly connected to the injection pipe 52. An injection channel 55 is provided on the support plate 54, and the injection channel 55 is connected to the injection pipe 52.

[0064] A conversion ring 61 is rotatably connected to the support plate 54. Multiple injection cylinders 62 are fixedly connected to the conversion ring 61. The injection cylinders 62 can communicate with the injection channel 55. A connecting pipe 63 is fixedly connected to the injection cylinder 62. A one-way mechanism 64 is provided inside the connecting pipe 63. A telescopic mechanism Ⅲ 65 is fixedly connected to the injection cylinder 62. A sliding plate 66 is fixedly connected to the telescopic end of the telescopic mechanism Ⅲ 65. The sliding plate 66 is slidably connected inside the injection cylinder 62.

[0065] The one-way limiting directions of the one-way mechanisms 64 installed in adjacent connecting pipes 63 are opposite;

[0066] A power mechanism Ⅲ for rotating a drive conversion ring 61 is fixedly connected to the support plate 54. The power mechanism Ⅲ is preferably a servo motor.

[0067] When using, such as Figure 4As shown, the raw material pipes of the bottom layer 11, elastic layer 12 and contact layer 13 are sequentially connected to three injection cylinders 62. It should be noted that there are six injection cylinders 62 here. The connecting pipes 63 on three injection cylinders 62 are connected to the raw material pipes, and the connecting pipes 63 on the other three injection cylinders 62 are connected to the discharge pipes. The one-way mechanism 64 in the connecting pipe 63 connected to the raw material pipe is used to ensure that the raw material can only enter the connecting pipe 63 from the raw material pipe. The one-way mechanism 64 in the connecting pipe 63 connected to the discharge pipe is used to ensure that the raw material can only be discharged from the connecting pipe 63 into the discharge pipe. The three injection cylinders 62 connected to the raw material pipe and the three injection cylinders 62 connected to the discharge pipe are arranged alternately.

[0068] Start the telescopic mechanism I 41, which can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism I 41 drives the bottom mold 42 to move, so that the bottom mold 42 is inserted into the molding groove 32. Start the telescopic mechanism II 51, which can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism II 51 drives the injection mold 53 to move, so that the injection mold 53 moves downward and slides into the molding groove 32.

[0069] When the power mechanism III is started, the output shaft of the power mechanism III begins to rotate. The output shaft of the power mechanism III drives the conversion ring 61 to rotate, and the conversion ring 61 drives multiple injection cylinders 62 to rotate. This allows the multiple injection cylinders 62 to pass through the injection channel 55 in sequence. When the injection cylinder 62 connected to the raw material pipe corresponding to the bottom layer 11 moves to the position connected to the injection channel 55, the telescopic mechanism III 65 is started. The telescopic mechanism III 65 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism III 65 drives the sliding plate 66 to move, so that the sliding plate 66 slides inside the injection cylinder 62. The sliding plate 66 injects the raw material of the bottom layer 11 in the injection cylinder 62 into the injection channel 55, and then into the injection mold 53. The injection mold 53 injects the raw material of the bottom layer 11 into the bottom mold 42 in the molding groove 32 through multiple injection holes, thereby completing the injection of the bottom layer 11.

[0070] Start the power mechanism III. The output shaft of the power mechanism III drives multiple injection cylinders 62 to rotate, so that the injection cylinder 62 adjacent to the injection cylinder 62 connected to the discharge pipe and the raw material pipe of the bottom layer 11 moves to the side of the injection channel 55. Start the telescopic mechanism III 65. The telescopic end of the telescopic mechanism III 65 drives the sliding plate 66 to move. The sliding plate 66 draws the raw material of the bottom layer 11 remaining in the injection channel 55 and the injection mold 53 into the injection cylinder 62.

[0071] The power mechanism III is started, and the output shaft of the power mechanism III drives multiple injection cylinders 62 to rotate. This causes the injection cylinder 62, which is connected to the raw material pipeline of the elastic layer 12, to inject the raw material into the injection channel 55. The telescopic mechanism III 65 is then started, causing the sliding plate 66 to slide inside the injection cylinder 62. The injection cylinder 62 injects the raw material of the elastic layer 12 into the injection channel 55, and then into the injection mold 53. The injection mold 53 injects the raw material of the elastic layer 12 into the bottom layer 11 through multiple injection holes, thereby completing the injection molding of the elastic layer 12.

[0072] Start the power mechanism III. The output shaft of the power mechanism III drives multiple injection cylinders 62 to rotate, so that the injection cylinder 62 adjacent to the injection cylinder 62 connected to the discharge pipe and the raw material pipe of the elastic layer 12 moves to the side of the injection channel 55. Start the telescopic mechanism III 65. The telescopic end of the telescopic mechanism III 65 drives the sliding plate 66 to move. The sliding plate 66 draws the raw material of the elastic layer 12 remaining in the injection channel 55 and the injection mold 53 into the injection cylinder 62.

[0073] The power mechanism III is started, and the output shaft of the power mechanism III drives multiple injection cylinders 62 to rotate. This causes the injection cylinder 62, which is connected to the raw material pipeline of the contact layer 13, to inject the raw material into the injection channel 55. The telescopic mechanism III 65 is then started, causing the sliding plate 66 to slide inside the injection cylinder 62. The injection cylinder 62 injects the raw material of the contact layer 13 into the injection channel 55, and then into the injection mold 53. The injection mold 53 injects the raw material of the contact layer 13 into the elastic layer 12 through multiple injection holes, thereby completing the injection molding of the contact layer 13.

[0074] Start the power mechanism III. The output shaft of the power mechanism III drives multiple injection cylinders 62 to rotate, so that the injection cylinder 62 adjacent to the injection cylinder 62 connected to the discharge pipe and the raw material pipe of the contact layer 13 moves to the side of the injection channel 55. Start the telescopic mechanism III 65. The telescopic end of the telescopic mechanism III 65 drives the sliding plate 66 to move. The sliding plate 66 draws the raw material of the contact layer 13 remaining in the injection channel 55 and the injection mold 53 into the injection cylinder 62.

[0075] Then, the injection molding process of the bottom layer 11, the elastic layer 12, and the contact layer 13 is completed;

[0076] Furthermore, in order to ensure the stability of the connection between the bottom layer 11, the elastic layer 12 and the contact layer 13, an ultrasonic generator 34 is also provided to start the telescopic mechanism I 41. The telescopic end of the telescopic mechanism I 41 can drive the bottom mold 42 to move, thereby adjusting the height of the upper side of the bottom layer 11, the elastic layer 12 and the contact layer 13.

[0077] When the elastic layer 12 is injected onto the upper side of the bottom layer 11, the ultrasonic generator 34 generates ultrasonic waves that pass through the contact surface between the elastic layer 12 and the bottom layer 11, forming a corrugated contact surface between the elastic layer 12 and the bottom layer 11. When the contact layer 13 is injected onto the upper side of the elastic layer 12, the ultrasonic generator 34 generates ultrasonic waves that pass through the contact surface between the contact layer 13 and the elastic layer 12, forming a corrugated contact surface between the contact layer 13 and the elastic layer 12. Furthermore, when the bottom layer 11, the elastic layer 12, and the contact layer 13 are injection molded but have not yet completely cooled, the ultrasonic generator 34 generates ultrasonic waves that pass through the contact surface between the elastic layer 12 and the bottom layer 11, and through the contact surface between the contact layer 13 and the elastic layer 12, thereby forming a corrugated contact surface between the elastic layer 12 and the bottom layer 11, and between the contact layer 13 and the elastic layer 12. This increases the contact area between the bottom layer 11, the elastic layer 12, and the contact layer 13, and produces an irregular shape, ensuring the stability of the connection between the bottom layer 11, the elastic layer 12, and the contact layer 13.

[0078] Furthermore, the power mechanism II can be activated. The output shaft of the power mechanism II drives the rotating ring 33 to rotate. The rotating ring 33 drives the ultrasonic generator 34, so that the ultrasonic waves generated by the ultrasonic generator 34 pass through the contact surface between the elastic layer 12 and the bottom layer 11, and the contact surface between the contact layer 13 and the elastic layer 12 from different angles, resulting in an irregular contact surface.
