Description

Technical Field

[0001] This invention relates to the field of molding and processing technology, and in particular to a double-layer shoe sole molding die and molding process. Background Technology

[0002] Double-layer sole molding is a manufacturing process that combines two different materials or sole components with different properties to form a complete sole. Double-layer soles can combine the advantages of different materials, giving the sole excellent wear resistance, elasticity, support, and other properties simultaneously. This effectively increases the overall thickness and strength of the sole, improving its durability and lifespan.

[0003] Traditional double-layer shoe sole molding involves several steps: inner layer molding, outer layer molding, curing and cooling, and demolding. These different steps require different locations or operators, resulting in a decentralized workflow that consumes significant production space, is lengthy and complex, and drastically reduces overall mold-forming efficiency, making it unsuitable for double-layer shoe sole molding. Furthermore, because it involves two molding operations, two sets of molds are needed. The traditional method of bolting the molds is cumbersome and inefficient. Moreover, with the development of footwear and the emergence of various double-layer shoe sole designs, mold replacement further limits molding efficiency.

[0004] Based on the above reasons, this invention proposes a double-layer shoe sole forming mold and forming process, which improves the convenience and efficiency of mold fixing and installation, so as to adapt to the mold system for forming and processing double-layer shoe soles of various specifications. At the same time, it realizes the integration of each forming process into a set of equipment, completes multi-process synchronous processing operations, thereby significantly improving the overall forming efficiency. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A double-layer shoe sole forming mold includes an outer shell. The outer shell has a square cross-section and three through slots and a feed port on its side wall. Four first molds are arranged in an array inside the outer shell, and a rotating shell is located at the center. An mounting plate is provided on the first mold. An installation frame is fixedly connected to the outer shell at the front through slot. A second mold is provided inside the installation frame. Mold mounting components are provided on both the mounting plate and the installation frame. A position adjustment component is provided between the rotating shell and the mounting plate. A rotating component is provided on the bottom surface of the inner cavity of the outer shell. Auxiliary mounting components are provided at the two through slots on the left and right sides. A lifting component is provided inside the rotating shell.

[0007] Preferably, the mold mounting assembly includes a horizontal plate, and the mounting plate and the mounting frame are provided with horizontal plates on the upper and lower sides. The horizontal plate is fixedly connected with a positioning rod. The first mold and the second mold are both provided with positioning grooves that match the positioning rods. The positioning rods pass through the mounting plate and the mounting frame and are inserted into the positioning grooves.

[0008] Preferably, a first spring is sleeved on the positioning rod, one end of the first spring is fixedly connected to the horizontal plate, and the other end of the first spring is fixedly connected to the mounting plate and the outer wall of the mounting frame respectively.

[0009] Preferably, the position adjustment assembly includes movable frames, and two movable frames are symmetrically fitted on the rotating shell. Each movable frame has four connecting plates hinged to its side wall. The connecting plates are hinged to a mounting plate on the side away from the movable frame. Four first threaded rods are threadedly connected to the two movable frames. Both ends of the first threaded rods are movably connected to the rotating shell, and a sprocket is fixedly connected to the top end. The same chain is fitted on the four sprockets. A first motor is fixedly connected to the top end of one of the first threaded rods. The first motor is fixedly connected to the rotating shell.

[0010] Preferably, the rotating assembly includes a ring gear, which is fixedly connected to the rotating shell. A first gear meshes with one side of the ring gear, and a rotating shaft is fixedly connected to the center of the side wall of the first gear. One end of the rotating shaft is movably connected to the shell, and the other end is fixedly connected to a second motor. A side plate fixed to the shell is fixedly connected to the second motor.

[0011] Preferably, the auxiliary installation component includes a flat plate, and the left and right side walls of the housing are fixedly connected to the flat plate at the upper side of the through groove. An electric push rod is fixedly connected to the flat plate, and an equipment fixing plate is fixedly installed at the bottom end of the electric push rod.

[0012] Preferably, the lifting assembly includes a vertical plate located inside the rotating shell cavity and movably connected to the outer shell. A threaded hole is provided on the top surface of the vertical plate, and a second threaded rod is threadedly connected to the threaded hole. The top end of the second threaded rod passes through the top surface of the rotating shell and is fixedly connected to a third motor. The third motor is fixedly connected to the top surface of the rotating shell.

[0013] Preferably, the first threaded rod has its upper and lower threads arranged in opposite directions with its sidewall center as the center of the axis of rotation, and the meshing directions between the upper and lower movable frames and the first threaded rod are arranged in opposite directions.

[0014] Preferably, the central cross-section of the rotating shell is square and the upper and lower sides are circular, and the cross-section of the vertical plate is matched with the inner sidewall of the rotating shell.

[0015] The molding process of a double-layer shoe sole mold includes the following steps: S1: Start the third motor. The third motor drives the second threaded rod to rotate. The second threaded rod engages with the threaded hole on the vertical plate, causing the rotating shell to move out from the top surface of the outer shell. The movement of the rotating shell can drive the mounting plate to move upward together. Driven by the third motor, when the mounting plate has completely moved out of the inner cavity of the outer shell, the operation of the third motor stops. S2: Pull the horizontal plates on both sides of the mounting plate. The horizontal plates drive the positioning rod to move and the first spring is stretched. At this time, the first mold for double-layer shoe sole forming is placed inside the mounting plate in the correct direction. Release the horizontal plates. Under the elastic force of the first spring, the positioning rod is inserted into the positioning groove on the side wall of the first mold, realizing the quick installation operation between the first mold and the mounting plate. Similarly, the second mold is quickly installed inside the mounting frame. S3: Reverse drive the third motor, the third motor drives the second threaded rod to rotate in the opposite direction, causing the rotating shell to move into the inner cavity of the outer shell. When the vertical plate is fully inserted into the inner cavity of the rotating shell and the ring gear meshes with the first gear, the operation of the third motor stops. S4: Install an adhesive spraying device for double-layer shoe sole production on one side of the equipment mounting plate, and install a robotic arm for removing the double-layer shoe sole on the other side of the equipment mounting plate. Complete the debugging operation and complete the installation operation of the auxiliary equipment used in the double-layer shoe sole production process. S5: During the double-layer sole forming process, the first motor is started, which drives the first threaded rod to rotate. The first threaded rod drives the sprocket to rotate. Through the transmission of the sprocket and the chain, the four first threaded rods rotate together. The first threaded rods engage with the movable frame, and the two movable frames move closer to each other on the rotating shell. The movable frame pushes the mounting plate through the connecting plate, so that the first mold on the mounting plate is connected to the feed port. A raw material for double-layer sole production can be injected into the first mold through external equipment, so that one layer of the double-layer sole can be formed through the first mold. Through the operation of the external cooling equipment, the forming of one layer of the sole is completed. S6: Reverse drive the first motor, as described above, to make the movable frames move away from each other, thereby retracting the first mold into the inner cavity of the outer shell and starting the second motor. The second motor drives the rotating shaft to rotate, and the rotating shaft drives the first gear to rotate. Through the meshing of the first gear with the ring gear, the ring gear drives the rotating shell to rotate. When the rotating shell rotates 90 degrees, the rotation of the second motor stops. Repeat the above steps S5 to allow the glue spraying equipment to complete the glue application on the molded layer of shoe sole, and to process another layer of shoe sole through another first mold. S7: Repeat steps S5 and S6 to achieve mold closing between the first mold and the second mold. Add another raw material for the double-layer sole into the inner cavity of the second mold to achieve molding processing of the second layer material of the double-layer sole. Use glue to bond the two layers of sole together to complete the molding processing of the double-layer sole. At the same time, it can also complete the production of another first layer sole and the glue application operation of the first layer sole. S8: By repeatedly performing step S7, the formed double-layer sole can be transferred to one side of the robot arm. By pushing the electric push rod, the equipment fixing plate can drive the robot arm to remove the formed double-layer sole from the first mold. The other three positions can also perform continuous processing operations on the sole, thus greatly improving the forming efficiency of the double-layer sole forming mold.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: This invention lifts the mounting plate out of the housing by operating the lifting component, facilitating the installation of the first mold on the mounting plate. By pulling the horizontal plates on both sides of the mounting plate, the horizontal plates drive the positioning rod to move and the first spring is stretched. At this time, the first mold for double-layer shoe sole molding is placed inside the mounting plate in the correct direction. Releasing the horizontal plates allows the positioning rod to be inserted into the positioning groove on the side wall of the first mold under the elastic force of the first spring, realizing a quick installation operation between the first mold and the mounting plate. Similarly, the second mold can be quickly installed into the mounting frame, effectively improving the convenience and efficiency of mold fixing and installation. This invention enables the first mold to move towards the through slot and the feed port through the operation of the position adjustment component, thereby realizing the simultaneous performance of multiple processes such as one-layer molding, glue spraying, two-layer molding and material unloading, which significantly improves the overall molding efficiency. Furthermore, through the operation of the rotating component, the first mold can be continuously switched between different process positions, effectively improving the efficiency of double-layer shoe sole molding.

The shell 1 has a square cross-section and three through slots 2 and a feed port 3 on its side wall. Four first molds 4 are arranged in an array inside the shell 1 and a rotating shell 5 is arranged at the center. An mounting plate 6 is provided on the first mold 4. An installation frame 7 is fixedly connected to the shell 1 at the front through slot 2. A second mold 8 is provided inside the installation frame 7. Mold installation components 9 are provided on both the mounting plate 6 and the installation frame 7. The mold installation components 9 include a horizontal plate 14. Horizontal plates 14 are provided on the upper and lower sides of the mounting plate 6 and the installation frame 7. A positioning rod 15 is fixedly connected to the horizontal plate 14.

One end of the first spring 16 is fixedly connected to the horizontal plate 14, and the other end of the first spring 16 is fixedly connected to the outer wall of the mounting plate 6 and the installation frame 7 respectively. In the technical solution of this embodiment, by pulling the horizontal plates 14 on both sides of the mounting plate 6, the horizontal plates 14 drive the positioning rod 15 to move and the first spring 16 is stretched. At this time, the first mold 4 for double-layer shoe sole forming processing is placed inside the mounting plate 6 in the correct direction. The horizontal plates 14 are released, and under the elastic force of the first spring 16, the positioning rod 15 is inserted into the positioning groove on the side wall of the first mold 4, realizing the quick installation operation between the first mold 4 and the mounting plate 6. Similarly, the second mold 8 is quickly installed inside the mounting frame 7, effectively improving the convenience and efficiency of mold fixing and installation. A position adjustment assembly 10 is provided between the rotating shell 5 and the mounting plate 6. The position adjustment assembly 10 includes a movable frame 17. Two movable frames 17 are symmetrically fitted on the rotating shell 5. Four connecting plates 18 are hinged to the side wall of each movable frame 17. The side of the connecting plate 18 away from the movable frame 17 is hinged to the mounting plate 6. Four first threaded rods 19 are threadedly connected to the two movable frames 17.

The first threaded rod 19 is symmetrical about the center of its side wall, and the threads on the upper and lower sides are arranged in opposite directions. The meshing directions between the upper and lower movable frames 17 and the first threaded rod 19 are arranged in opposite directions. In the technical solution of this embodiment, during the double-layer shoe sole molding process, the first motor 22 is started, which drives the first threaded rod 19 to rotate. The first threaded rod 19 drives the sprocket 20 to rotate. Through the transmission between the sprocket 20 and the chain 21, the four first threaded rods 19 rotate together. The first threaded rods 19 engage with the movable frame 17 to move. The two movable frames 17 move closer or further away from each other on the rotating shell 5. The movable frame 17 drives the mounting plate 6 to move through the connecting plate 18. If the connecting plate 18 pulls the mounting plate 6 to move, the first mold 4 can be pulled back into the inner cavity of the outer shell 1, which is convenient for switching between processes.

The cross section of the vertical plate 32 is matched with the inner side wall of the rotating shell 5. In the technical solution of this embodiment, by starting the third motor 24, the third motor 24 drives the second threaded rod 33 to rotate. The second threaded rod 33 engages with the threaded hole on the vertical plate 32, thereby causing the rotating shell 5 to move out from the top surface of the outer shell 1. The movement of the rotating shell 5 can drive the mounting plate 6 to move upward together. When the mounting plate 6 has completely moved out of the inner cavity of the outer shell 1, the installation operation between the first mold 4 and the mounting plate 6 can be realized, improving the convenience and efficiency of the installation of the first mold 4.

[0028] The molding process of a double-layer shoe sole mold includes the following steps: S1: Start the third motor 24. The third motor 24 drives the second threaded rod 33 to rotate. The second threaded rod 33 engages with the threaded hole on the vertical plate 32, thereby causing the rotating shell 5 to move out from the top surface of the outer shell 1. The movement of the rotating shell 5 can drive the mounting plate 6 to move upward together. Under the drive of the third motor 24, when the mounting plate 6 has completely moved out of the inner cavity of the outer shell 1, the operation of the third motor 24 is stopped. S2: Pull the horizontal plates 14 on both sides of the mounting plate 6. The horizontal plates 14 drive the positioning rod 15 to move and the first spring 16 is stretched. At this time, the first mold 4 used for double-layer shoe sole forming is placed inside the mounting plate 6 in the correct direction. Release the horizontal plates 14. Under the elastic force of the first spring 16, the positioning rod 15 is inserted into the positioning groove on the side wall of the first mold 4, realizing the quick installation operation between the first mold 4 and the mounting plate 6. Similarly, the second mold 8 is quickly installed inside the mounting frame 7. S3: Reverse drive the third motor 24, the third motor 24 drives the second threaded rod 33 to rotate in the opposite direction, so that the rotating shell 5 moves into the inner cavity of the outer shell 1. When the vertical plate 32 is fully inserted into the inner cavity of the rotating shell 5 and the ring gear 23 meshes with the first gear 25, the operation of the third motor 24 stops. S4: Install an adhesive spraying device for double-layer shoe sole production on one side of the equipment fixing plate 31, and install a robotic arm for removing the double-layer shoe sole on the other side of the equipment fixing plate 31. Complete the debugging operation and complete the installation operation of the auxiliary equipment used in the double-layer shoe sole production process. S5: During the double-layer sole forming process, the first motor 22 is started, which drives the first threaded rod 19 to rotate. The first threaded rod 19 drives the sprocket 20 to rotate. Through the transmission between the sprocket 20 and the chain 21, the four first threaded rods 19 rotate together. The first threaded rods 19 engage with the movable frame 17 to move. The two movable frames 17 move closer to each other on the rotating shell 5. The movable frame 17 pushes the mounting plate 6 through the connecting plate 18, so that the first mold 4 on the mounting plate 6 is connected to the feed port 3. A raw material for double-layer sole production can be added to the first mold 4 through external equipment, so that one layer of the double-layer sole can be formed through the first mold 4. Through the operation of the external cooling equipment, the forming of one layer of the sole is completed. S6: Reverse drive the first motor 22, as described above, to make the movable frame 17 move away from each other, thereby retracting the first mold 4 into the inner cavity of the outer shell 1 and starting the second motor 27. The second motor 27 drives the rotating shaft 26 to rotate, and the rotating shaft 26 drives the first gear 25 to rotate. The first gear 25 meshes with the ring gear 23 to rotate, and the ring gear 23 drives the rotating shell 5 to rotate. When the rotating shell 5 rotates 90 degrees, the rotation of the second motor 27 is stopped. Repeat the above steps S5 to make the glue spraying equipment complete the glue application on the molded layer of shoe sole, and another layer of shoe sole can be formed and processed through another first mold 4. S7: Repeat steps S5 and S6 to achieve mold closing between the first mold 4 and the second mold 8. Add another raw material for the double-layer sole into the inner cavity of the second mold 8 to achieve molding of the second layer material of the double-layer sole. Use glue to bond the two layers of sole together to complete the molding of the double-layer sole. At the same time, it can also complete the production of another first layer sole and the glue application operation of the first layer sole. S8: By repeatedly performing step S7, the formed double-layer sole can be transferred to one side of the robot arm. By pushing the electric push rod 30, the equipment fixing plate 31 can drive the robot arm to move and remove the formed double-layer sole from the first mold 4. The other three positions can realize continuous processing operations on the sole, which can fully improve the forming efficiency of the double-layer sole forming mold.

2. The double-layer shoe sole forming mold according to claim 1, characterized in that, The central cross-section of the rotating shell is square and the upper and lower sides are circular. The cross-section of the vertical plate is matched with the inner sidewall of the rotating shell.

3. The molding process of the double-layer shoe sole molding die according to any one of claims 1-2, characterized in that, Includes the following steps: S1: Start the third motor. The third motor drives the second threaded rod to rotate. The second threaded rod engages with the threaded hole on the vertical plate, causing the rotating shell to move out from the top surface of the outer shell. The movement of the rotating shell can drive the mounting plate to move upward together. Driven by the third motor, when the mounting plate has completely moved out of the inner cavity of the outer shell, the operation of the third motor stops. S2: Pull the horizontal plates on both sides of the mounting plate. The horizontal plates drive the positioning rod to move and the first spring is stretched. At this time, the first mold for double-layer shoe sole forming is placed inside the mounting plate in the correct direction. Release the horizontal plates. Under the elastic force of the first spring, the positioning rod is inserted into the positioning groove on the side wall of the first mold, realizing the quick installation operation between the first mold and the mounting plate. Similarly, the second mold is quickly installed inside the mounting frame. S3: Reverse drive the third motor, the third motor drives the second threaded rod to rotate in the opposite direction, causing the rotating shell to move into the inner cavity of the outer shell. When the vertical plate is fully inserted into the inner cavity of the rotating shell and the ring gear meshes with the first gear, the operation of the third motor stops. S4: Install an adhesive spraying device for double-layer shoe sole production on one side of the equipment mounting plate, and install a robotic arm for removing the double-layer shoe sole on the other side of the equipment mounting plate. Complete the debugging operation and complete the installation operation of the auxiliary equipment used in the double-layer shoe sole production process. S5: During the double-layer sole forming process, the first motor is started, which drives the first threaded rod to rotate. The first threaded rod drives the sprocket to rotate. Through the transmission of the sprocket and the chain, the four first threaded rods rotate together. The first threaded rods engage with the movable frame, and the two movable frames move closer to each other on the rotating shell. The movable frame pushes the mounting plate through the connecting plate, so that the first mold on the mounting plate is connected to the feed port. A raw material for double-layer sole production can be injected into the first mold through external equipment, so that one layer of the double-layer sole can be formed through the first mold. Through the operation of the external cooling equipment, the forming of one layer of the sole is completed. S6: Reverse drive the first motor, as in the reverse working process of step S5 above, so that the movable frames can move away from each other, thereby retracting the first mold into the inner cavity of the outer shell, and start the second motor. The second motor drives the rotating shaft to rotate, the rotating shaft drives the first gear to rotate, and the first gear meshes with the ring gear to rotate, and the ring gear drives the rotating shell to rotate. When the rotating shell rotates 90 degrees, stop the rotation of the second motor. Repeat the operation of step S5 above, so that the glue spraying equipment can complete the glue application on the molded layer of shoe sole, and another layer of shoe sole can be formed and processed by another first mold. S7: Repeat steps S5 and S6 to achieve mold closing between the first mold and the second mold. Add another raw material for the double-layer sole into the inner cavity of the second mold to achieve molding processing of the second layer material of the double-layer sole. Use glue to bond the two layers of sole together to complete the molding processing of the double-layer sole. At the same time, it can also complete the production of another first layer sole and the glue application operation of the first layer sole. S8: By repeatedly performing step S7, the formed double-layer sole can be transferred to one side of the robot arm. By pushing the electric push rod, the equipment fixing plate can drive the robot arm to remove the formed double-layer sole from the first mold. The other three positions can also perform continuous processing operations on the sole, thus greatly improving the forming efficiency of the double-layer sole forming mold.
