[0017] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0018] Reference Figure 1-6 As shown, a shoe sole material cutting structure includes a main body 1, a cutting mechanism 2 mounted on the main body 1, and a shoe sole demolding mechanism 3 mounted on the main body 1. The main body 1 has a forward and backward moving mechanism 4, a left and right moving mechanism 5, and a vertical moving mechanism 6 that drive the shoe sole demolding mechanism 3 to move in space. The vertical moving mechanism 6 is equipped with a drive assembly 8 that drives the shoe sole demolding mechanism 3 to rotate. The shoe sole demolding mechanism 3 removes the shoe sole from the mold and sends it to the cutting mechanism 2 to cut off the material 9. The mold is mounted on the main body 1 for forming the shoe sole, and the shoe sole demolding mechanism 3 is used to remove the formed shoe sole from the mold. The forward and backward moving mechanism 4, the left and right moving mechanism 5, and the up and down moving mechanism 6 are all installed on the main body of the equipment 1. The moving mechanism can drive the sole demolding mechanism 3 to move forward, backward, left, right, up and down in the main body of the equipment 1, so that the sole demolding mechanism 3 can achieve all-round position adjustment in space, ensuring that the sole demolding mechanism 3 can accurately move to the corresponding position of the mold for demolding operation. After the sole is removed by the sole demolding mechanism 3, it is transported to the cutting mechanism 2 to cut off the material head 9. During the production process of the sole, two material heads 9 will be generated. The first one is the material head 9 at the mold gate, and the second one is the long columnar material head 9 generated at the mold ejector pin. Since the two material heads 9 are not on the same plane, the sole demolding mechanism 3 is controlled to rotate by the drive component 8 to cooperate with the cutting mechanism 2 to cut the two material heads 9.

[0019] To improve the clamping and positioning effect of the cutting mechanism 2 on the shoe sole material head 9, in one optional embodiment, the cutting mechanism 2 includes a bracket 21 mounted on the main body 1, a positioning component mounted on the bracket 21, and a cutting device 22 mounted on the bracket 21. The cutting device 22 can be a pneumatic scissor or other cutting tool. The positioning component includes a flat plate 23 and a first cylinder 24 mounted on the flat plate 23. The flat plate 23 is provided with a baffle 25 that clamps and cooperates with the output shaft of the first cylinder 24. The baffle 25 clamps the shoe sole material head 9 by cooperating with the output shaft of the first cylinder 24, so as to facilitate the positioning of the shoe sole by the shoe sole demolding mechanism 3. The bracket 21 is fixed to the main body 1 by welding. The flat plate 23 of the positioning component is fixed to the bracket 21 by locking components. The baffle 25 is fixed to the flat plate 23 by locking components. The cutting device 22 is fixed to the bracket 21 by locking components. When the sole demolding mechanism 3 moves the sole to the cutting mechanism 2, the material head 9 generated by the mold ejector pin extends between the first cylinder 24 and the baffle 25. The material head 9 is pressed by the output shaft of the first cylinder 24. The sole demolding mechanism 3 then separates from the sole and presses and adsorbs it again for positioning, so as to facilitate the corresponding cutting position in the future.

[0020] Further optimization can be achieved by selecting the following method to enhance the auxiliary positioning effect of the first cylinder 24 on the sole: the first cylinder 24 is provided with an abutment surface for the suction cup to press against the sole. Providing an abutment surface on the first cylinder 24 enables the vacuum suction cup 33 to reliably adhere to the sole.

[0021] In some designs, to improve the gripping stability of the sole release mechanism 3 and avoid rigid damage, the sole release mechanism 3 includes a platform 31, a clamping mechanism 32 mounted on the platform 31, and a vacuum suction cup 33. The vacuum suction cup 33 is located below the clamping mechanism 32 and is mounted on the platform 31 via a buffer assembly 7. When the vacuum suction cup 33 is compressed, it moves relative to the platform 31 via the buffer assembly 7, thereby preventing the suction cup from causing rigid compression to the sole. The clamping mechanism 32 can be an electric gripper or a pneumatic gripper. The clamping mechanism 32 is mounted on the platform 31 and is used to clamp the sprue 9 generated by the gate on the sole during the demolding process. The vacuum suction cup 33 is connected to the platform 31 via the buffer assembly 7. When the vacuum suction cup 33 moves and contacts the sole and is subjected to the reaction force of the sole, the vacuum suction cup 33 moves relative to the platform 31, thereby buffering the squeezing force of the vacuum suction cup 33 on the sole and avoiding sole damage caused by rigid contact. In the actual demolding operation, the clamping mechanism 32 approaches the sole and clamps the material head 9 on the sole. Since the material head 9 is located below the sole, the clamping mechanism 32 drives the sole to rise and detach from the mold cavity, causing the sole to bend so that the vacuum suction cup 33 can adsorb and fix the sole, or the vacuum suction cup 33 can press the sole onto the mold surface for adsorption and fixation.

[0022] In some options, the drive assembly 8 includes an actuator 81 and a linkage 82. One side of the linkage 82 is fixedly connected to the platform 31, and the other side of the linkage 82 is rotatably connected to the actuator 81. The actuator 81 drives the linkage 82 to move, thereby driving the platform 31 to rotate, or the actuator 81 drives the linkage 82 to retract, thereby driving the platform 31 to rotate. In this embodiment, the actuator 81 can be a power component such as a hydraulic cylinder or a pneumatic cylinder. The actuator 81 is mounted on the up-and-down moving mechanism 6. The linkage 82 is an L-shaped connecting plate. The up-and-down moving mechanism 6 is provided with a rotating shaft. The L-shaped connecting plate is rotatably connected to the rotating shaft, and one side of it is fixedly connected to the platform 31. The output shaft of the actuator 81 is rotatably connected to the L-shaped connecting plate to drive the L-shaped connecting plate to rotate circumferentially along the rotating shaft, thereby causing the platform 31 to rotate so that the cutting device 22 can cut the material ends 9 on different planes of the shoe sole.

[0023] In some configurations, the cushioning assembly 7 includes a screw 71, a nut 72, and an elastic element 73. The screw 71 passes through the platform 31 and is locked onto the platform 31 by the nut 72. The vacuum suction cup 33 is movably mounted on the screw 71 along its axial direction and is reset by the elastic element 73 when compressed. The screw 71, after passing through the platform 31, is locked by the nut 72, achieving a fixed connection between the screw 71 and the platform 31, ensuring the stability of the entire cushioning assembly 7 mounted on the platform 31. The screw 71 guides the movement of the vacuum suction cup 33, preventing it from shifting during movement. The elastic element 73 is installed between the screw 71 and the vacuum suction cup 33. When the vacuum suction cup 33 is compressed and moves away from the sole along the axial direction of the screw 71 under pressure, the elastic element 73 is compressed or stretched and stores elastic potential energy. When the pressure disappears, the elastic element 73 releases its elastic potential energy, pushing the vacuum suction cup 33 back to its initial position along the axial direction of the screw 71.

[0024] Further optimization can be achieved by using the following method: A connecting rod 74 is provided on the vacuum suction cup 33, and a through hole 75 is provided on the screw 71 for the connecting rod 74 to pass through. An elastic element 73 is installed between the head of the screw 71 and the vacuum suction cup 33. A limiting part 76 is fixedly connected to the tail of the connecting rod 74 to prevent the connecting rod 74 from detaching from the screw 71. The pressure applied by the elastic element 73 to the vacuum suction cup 33 causes the limiting part 76 to abut against the screw 71 or nut 72. The connecting rod 74 on the vacuum suction cup 33 cooperates with the through hole 75 on the screw 71. The connecting rod 74 passes through the through hole 75, allowing the vacuum suction cup 33 to form a movable connection with the screw 71 through the connecting rod 74. The through hole 75 guides the movement of the connecting rod 74, further ensuring the stability of the vacuum suction cup 33's axial movement along the screw 71 and preventing radial displacement of the vacuum suction cup 33. The elastic element 73 can be a spring, which is sleeved on the connecting rod 74. One end of the spring abuts against the head of the screw 71, and the other end abuts against the vacuum suction cup 33.

[0025] In some options, the platform 31 is provided with an oblong hole 10 for mounting the screw 71. The oblong hole 10 on the platform 31 is set along the length or width direction of the platform 31. The screw 71 passes through the oblong hole 10 and is locked by the nut 72. Since the oblong hole 10 has a certain length, after the nut 72 is loosened, the screw 71 can move along the length direction of the oblong hole 10, thereby adjusting the horizontal position of the vacuum suction cup 33 on the platform 31, so as to better cope with different shapes of shoe soles and improve the flexibility of vacuum suction cup 33 installation.

[0026] To further improve the adhesion stability and demolding effect of the vacuum suction cup 33 to the shoe sole, in one optional scheme, two vacuum suction cups 33 are provided. Both vacuum suction cups 33 are mounted on the platform 31 via buffer components 7. Both vacuum suction cups 33 are located below the clamping mechanism 32 and arranged along the height direction of the platform 31. Each of the two vacuum suction cups 33 is mounted on the platform 31 via an independent buffer component 7. The distance between the two vacuum suction cups 33 can be adjusted according to the shape and size of the shoe sole, ensuring that each vacuum suction cup 33 can adhere to different areas of the shoe sole. This results in a more even distribution of adhesion force on the shoe sole, preventing deformation or detachment due to uneven force caused by single-point adhesion. Both vacuum suction cups 33 are located below the clamping mechanism 32 and arranged along the height direction of the platform 31, meaning the clamping mechanism 32 and the two vacuum suction cups 33 are arranged sequentially in the vertical direction.

[0027] Further optimization can be achieved by arranging multiple sets of clamping mechanisms 32, vacuum suction cups 33, and cushioning components 7 on platform 31, with the number of sets corresponding to the number of cavities in the mold. When the mold is a multi-cavity mold, meaning that multiple cavities for producing shoe soles are set on one mold, multiple sets of clamping mechanisms 32, vacuum suction cups 33, and cushioning components 7 are arranged on platform 31, with each set of mechanisms corresponding to one mold cavity. This arrangement allows the demolding mechanism to simultaneously demold multiple cavities on the mold, improving demolding efficiency.

[0028] In some designs, the side of the vacuum suction cup 33 that abuts against the sole is provided with a sponge 11. When the vacuum suction cup 33 contacts the sole, the sponge 11 first contacts the sole surface, further cushioning the pressure of the vacuum suction cup 33 on the sole and preventing scratches or indentations caused by the hard edge of the vacuum suction cup 33 directly contacting the sole surface. Simultaneously, the sponge 11 has a certain degree of deformability, allowing it to conform closely to sole surfaces of different shapes and surface roughness, reducing air leakage during the suction process and improving the suction force and stability of the vacuum suction cup 33.

[0029] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
