[0025] A shoe sole forming mold includes two opposing movable mold bodies 11, with a rotating mold body 5 rotatably disposed between the two movable mold bodies 11. During the process of the movable mold bodies 11 moving towards each other, they can contact the rotating mold body 5 and enclose a mold cavity for processing shoe sole units. A position control mechanism 9 is also provided on the movable mold body 11, which is used to control the position of the shoe sole unit during the movement of the movable mold body 11.

[0026] During the sole processing, the rotating mold 5 is first rotated, positioning it between two movable molds 11. Then, the two movable molds 11 are moved until both are in contact with the rotating mold 5, thus creating two cavities for processing sole units. The two processed sole units are different; for example, one sole unit is a durable outsole, and the other is a cushioning midsole. After processing, the two movable molds 11 are moved in opposite directions, and the position control mechanism 9 controls the sole unit to remain in contact with the movable molds 11 while simultaneously separating it from the rotating mold 5. Glue is then applied to one of the sole units, and the two movable molds 11 are moved again until the two sole units are bonded together with glue. The two bonded sole units can then be completely demolded, separating from one of the movable molds 11.

[0027] The molding die of the present invention can process two different sole units simultaneously and can directly fix the two sole units together by bonding, which can reduce processing steps and improve processing efficiency.

[0028] To facilitate the setting of two movable mold bodies 11 and one rotating mold body 5, the mold also includes a connecting plate 1. The connecting plate 1 is fixedly connected to two connecting blocks 2. The connecting blocks 2 are fixedly connected to a positioning frame 6. The movable mold body 11 is slidably set in the positioning frame 6. A rotary shaft 3 is also fixedly connected between the two connecting blocks 2. A rotating sleeve 4 is rotatably sleeved on the rotary shaft 3. The rotating sleeve 4 is fixedly connected to the rotating mold body 5.

[0029] The positioning frame 6 is fixedly connected to multiple connecting rods 7, and all connecting rods 7 are fixedly connected to a mounting plate 8. The position control mechanism 9 is fixedly mounted on the mounting plate 8, and the mounting plate 8 is also fixedly connected to a driver 10 for pushing the moving mold 11. The positioning frame 6 can restrict the movement direction of the moving mold 11 to prevent the moving mold 11 from tilting.

[0030] Because the rotating mold 5 needs to be in precise contact with both moving molds 11, otherwise the mold cavity will deform, it is necessary to lock the relative position of the rotating mold 5 and the two moving molds 11. To achieve this effect and facilitate the rotation of the rotating mold 5, a push rod 16 is fixedly connected to the rotating mold 5 to drive the rotating mold 5 to rotate around the rotation axis 3. The mold also includes a locking mechanism for locking the position of the push rod 16. During the processing of the shoe sole, the rotating mold 5 can be driven to rotate around the rotation axis 3 by pushing the push rod 16, which is simple to operate. After the two moving molds 11 are in contact with the rotating mold 5 to form two mold cavities, the position of the push rod 16 is locked by the locking mechanism, thereby locking the relative position of the rotating mold 5 and the moving molds 11 and preventing the rotating mold 5 from shifting and causing mold cavity deformation.

[0031] For ease of operation, the locking mechanism in this invention includes a swing rod 14 rotatably connected to a push rod 16 via a swing shaft 15 and a positioning rod 12 fixedly mounted on one of the positioning frames 6. The positioning rod 12 has a positioning groove 13, allowing the swing rod 14 to insert into the positioning groove 13 during swinging. After the rotating mold body 5 and both moving mold bodies 11 have contact to form two mold cavities, the swing rod 14 is rotated around the swing shaft 15 until it is inserted into the positioning groove 13, thus locking the position of the rotating mold body 5 and preventing it from tilting during molding. A friction layer can be provided on the swing shaft 15 to prevent the swing rod 14 from dislodging from the positioning groove 13 without external force.

[0032] The position control mechanism 9 includes a sleeve fixedly connected to the mounting plate 8. A telescopic moving rod 18 is installed in the sleeve and fixedly connected to the moving mold body 11. A cavity 19 communicating with the mold cavity is opened on the moving rod 18. The cavity 19 is connected to an airflow controller through an air guide pipe 21. A sealing head 22 is also movably installed in the cavity 19 to close the communication position between the cavity 19 and the mold cavity. During the molding process of the sole unit, the sealing head 22 closes the communication position between the cavity 19 and the mold cavity to prevent raw materials from entering the cavity 19. After molding is completed, the sealing head 22 opens the communication position between the cavity 19 and the mold cavity, and then the airflow controller controls the formation of positive or negative pressure in the cavity 19. When it is negative pressure, it can attract the sole unit to move with the moving mold body 11. When it is positive pressure, it can push the sole unit to separate from the moving mold body 11, completing demolding. This position control mechanism 9 controls the position of the sole unit pneumatically, eliminating the need for a complex gripping structure and simplifying the process.

[0033] To drive the sealing head 22 to move, a telescopic push rod 20 is fixedly installed in the cavity 19. The telescopic push rod 20 drives the sealing head 22 to move within the cavity 19. The telescopic push rod 20 can adopt a structure similar to a cylinder, which is a conventional technology and will not be described in detail here. A retaining ring 23 is fixedly installed on the inner wall of the cavity 19 at the position where it communicates with the mold cavity. During the movement of the sealing head 22, it can enter the inner hole of the retaining ring 23.

[0034] To facilitate connection to the feeding device that inputs raw materials into the mold cavity, the movable mold body 11 is provided with a material inlet 17 for inputting raw materials into the mold cavity. Since the movement trajectory of the movable mold body 11 is a straight line, while the movement trajectory of the rotating mold body 5 is an arc, placing the material inlet 17 on the movable mold body 11 facilitates connection to the feeding device and avoids pipe entanglement.

[0035] In one specific embodiment of the present invention, a shoe sole forming mold includes two opposing movable mold bodies 11, with a rotating mold body 5 rotatably disposed between the two movable mold bodies 11. During the movement of the movable mold bodies 11 towards each other, they can contact and enclose a mold cavity for processing shoe sole units. A position control mechanism 9 is also provided on each movable mold body 11, used to control the position of the shoe sole unit during the movement of the movable mold body 11. The mold also includes a connecting plate 1, with two connecting blocks 2 fixedly connected to the connecting plate 1, and a positioning frame 6 fixedly connected to each connecting block 2. The movable mold body 11 is correspondingly slidably disposed within the positioning frame 6. A rotating shaft 3 is also fixedly connected between the two connecting blocks 2, and a rotating sleeve 4 is rotatably sleeved on the rotating shaft 3, the rotating sleeve 4 being fixedly connected to the rotating mold body 5.

[0036] The positioning frame 6 is fixedly connected to multiple connecting rods 7, and all connecting rods 7 are fixedly connected to a mounting plate 8. A position control mechanism 9 is fixedly mounted on the mounting plate 8. The mounting plate 8 is also fixedly connected to a driver 10 for pushing the moving mold body 11. The positioning frame 6 can restrict the movement direction of the moving mold body 11 to prevent it from tilting. The rotating mold body 5 is fixedly connected to a push rod 16 for driving the rotating mold body 5 to rotate around the rotation axis 3. The mold also includes a locking mechanism for locking the position of the push rod 16. During the processing of the shoe sole, the rotating mold body 5 can be driven to rotate around the rotation axis 3 by pushing the push rod 16, making operation simple. After both moving mold bodies 11 contact the rotating mold body 5 to form two mold cavities, the locking mechanism is used... The mechanism locks the position of the push rod 16, thereby locking the relative positions of the rotating mold body 5 and the moving mold body 11, preventing the rotating mold body 5 from shifting and causing mold cavity deformation. The locking mechanism includes a swing rod 14 rotatably connected to the push rod 16 via a swing shaft 15 and a positioning rod 12 fixedly mounted on one of the positioning frames 6. The positioning rod 12 has a positioning groove 13. During the swinging process, the swing rod 14 can be inserted into the positioning groove 13. After the rotating mold body 5 and the two moving mold bodies 11 have contact to form two mold cavities, the swing rod 14 is rotated to rotate around the swing shaft 15 until the swing rod 14 is inserted into the positioning groove 13, thus locking the position of the rotating mold body 5 and preventing the rotating mold body 5 from tilting during the molding process. A friction layer is provided to prevent the swing rod 14 from dislodging from the positioning groove 13 without external force. The position control mechanism 9 includes a sleeve fixedly connected to the mounting plate 8. A moving rod 18 is telescopically installed in the sleeve and fixedly connected to the moving mold body 11. A cavity 19 communicating with the mold cavity is opened on the moving rod 18. The cavity 19 is connected to an airflow controller through an air guide pipe 21. A sealing head 22 is also movably installed in the cavity 19 to close the communication position between the cavity 19 and the mold cavity. During the molding process of the sole unit, the sealing head 22 closes the communication position between the cavity 19 and the mold cavity to prevent raw materials from entering the cavity 19. After molding is completed, the sealing head 22 closes the communication position between the cavity 19 and the mold cavity. The position is opened, and then the airflow controller controls the formation of positive or negative pressure in the cavity 19. When it is negative pressure, it can attract the sole unit and make it move with the moving mold 11. When it is positive pressure, it can push the sole unit to separate it from the moving mold 11, thus completing the demolding. The position control mechanism 9 controls the position of the sole unit pneumatically, which does not require a complex gripping structure and is simpler. A telescopic push rod 20 is fixedly installed in the cavity 19. The telescopic push rod 20 drives the sealing head 22 to move in the cavity 19. The telescopic push rod 20 can adopt a structure similar to a cylinder. A fixing ring 23 is fixedly installed on the inner wall of the cavity 19 where it communicates with the mold cavity. During the movement of the sealing head 22, it can enter the inner hole of the fixing ring 23.The movable mold 11 is provided with a material inlet 17 for feeding raw materials into the mold cavity. Since the moving trajectory of the movable mold 11 is a straight line, while the moving trajectory of the rotating mold 5 is an arc, setting the material inlet 17 on the movable mold 11 facilitates connection to the feeding equipment and avoids pipe entanglement.

The adhesive applicator includes a base 24, a robotic arm 25 fixedly mounted on the base 24, and an injection head 26 driven by the robotic arm 25.
