Description

Technical Field

[0001] The utility model belongs to the field of medical technology, and particularly relates to a shoe mold structure convenient for 3D printing. Background Art

[0002] 3D printing shoes is a process of precisely manufacturing shoe prototypes or directly producing finished shoes by 3D printing technology, layer by layer stacking materials (such as thermoplastic plastics, photocurable resins, or flexible TPU, etc.) according to digital design files. This technology can not only quickly realize the creativity of designers, but also improve the performance and comfort of shoes through complex internal structure design, bringing a more personalized wearing experience to consumers. For example, the patent application publication number CN219445822U, named a shoe mold structure convenient for 3D printing, has a supporting side wall extending downward along the periphery of the lower surface. Inside the area surrounded by the supporting side wall, there are multiple reinforcing rib strips crisscrossing each other. The multiple reinforcing rib strips enclose a hollow area, and multiple supporting columns are evenly distributed in the hollow area. The supporting columns extend downward, and the lower ends of the supporting side wall, the lower ends of the reinforcing rib strips, and the lower ends of the supporting columns are flush.

[0003] In the above patent, the sole formed by the multiple reinforcing rib strips crisscrossing each other and the hollow area surrounded by the multiple reinforcing rib strips can achieve the purpose of saving materials and having a lightweight structure. However, the seismic cushioning effect of the overall shoe bottom surface will be weakened, thereby reducing the wearing comfort.

[0004] Currently, when a mold core is 3D printed, a support structure needs to be set inside the mold core. Otherwise, if the internal hollow area is too large, the corresponding shoe mold position above the hollow area cannot be printed. After 3D printing, the support structure is removed through evacuation treatment, and it is difficult and cumbersome to remove the support structure by comprehensively distributing and supporting the shoe body. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a shoe mold structure convenient for 3D printing to solve the problems of wearing comfort and disassembly of the support structure in the prior art.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A shoe mold structure convenient for 3D printing includes a mold body integrally formed by 3D printing. A curved outer wall is distributed around the periphery of the mold body; the curved outer wall forms an elastic support part; a support framework is arranged below the mold body, and the support framework is used to stabilize the mold body during printing.

[0008] Further, a heel pad is provided on the surface of the mold body, and a corrugated surface is printed on one side of the heel pad.

[0009] In the above solution, the heel pad can increase the stability of the shoe. Especially when the heel is in a tight state, it helps prevent the foot from sliding or wobbling inside the shoe, ensuring the foot remains stable during walking or running. It can reduce the fatigue of the foot during running or walking. Provide additional support and cushioning, reduce the pressure on the foot, and make the foot still feel comfortable after long-term activities. The corrugated surface will separate the contact between the insole and the mold body, reduce the wear inside the mold body, and at the same time, the gap separated between the corrugated surface and the insole can help the internal air to disperse and circulate, reducing odors.

[0010] Further, the elastic support part includes an upper opening and a lower opening. The upper opening and the lower opening are respectively opened above and below the outer wall of the curve. The curvature of the lower opening bends towards the rear of the mold body. The upper openings are distributed between each lower opening. Among them, the upper opening is above the lower opening, and the upper opening is smaller than the lower opening.

[0011] In the above solution, when bending backward, the support contact on the outer wall of the curve will deform when contacting the ground, thereby improving the support effect. At the same time, the upper opening is used to absorb part of the deformation effect generated by the lower opening, further improving the support effect and the use comfort. Moreover, the combination of the lower opening and the upper opening can also accelerate the deformation reset of the outer wall of the curve.

[0012] Further, the outer wall of the curve gradually narrows forward from the rear of the mold body. The larger outer wall of the curve at the rear of the mold body can increase the rebound performance of the shoe, enabling it to more effectively convert energy into thrust during walking or running, improving the extension efficiency, and protecting key parts such as the knee joint. At the same time, the gradually narrowing outer wall of the curve of the mold body can effectively reduce the printing material of the overall mold body, making the mold body structure lighter.

[0013] Further, a fitting block is provided inside the lower opening. The fitting block can enhance the support effect of the elastic deformation of the lower opening. With the improvement of the elastic deformation support effect, the sole can better maintain its shape when subjected to pressure, providing stronger support and stability for the wearer's foot.

[0014] Further, the support framework includes support holes and support frames. A number of support holes are opened at the bottom end of the outer wall of the curve. Support frames are supported inside the support holes. A support block is provided at the bottom of the support frame, and a printing plate is provided at the bottom of the support block.

[0015] In the above solution, the support frames are supported in each support hole and fixed on the surface of the printing plate by the support blocks. The support blocks improve the stability effect of the support frames. Multiple support frames are evenly supported in the support holes to stabilize the printing operation of the mold body. At the same time, the support framework can be conveniently cleaned and disassembled after printing is completed.

[0016] Furthermore, connecting frames are cross - distributed among the support frames. The connecting frames cross - distributed on the support frames can further improve the stability effect of the support frames, enhance the lateral support effect of the support frames, and prevent the support frames from tilting.

[0017] The technical solution of the present utility model has the following beneficial effects:

[0018] 1. The elastic support part can effectively provide additional support for the feet. Especially during exercise, it can reduce the swaying and instability of the feet, thereby improving sports performance. It can effectively absorb and disperse the impact force from the ground, thereby reducing the vibration and damage suffered by the feet and increasing the wearing comfort. The outer wall of the curve gradually narrows forward from the rear of the mold body. In this way, the larger outer wall of the curve at the rear of the mold body can increase the rebound performance of the shoe. At the same time, the gradually narrowing outer wall of the curve of the mold body in sequence, combined with the lower opening and the upper opening, can effectively reduce the printing material of the overall mold body, and the structure of the mold body is lighter.

[0019] 2. Multiple support frames are evenly supported in the support holes to stabilize the printing operation of the mold body. At the same time, after printing is completed, it is convenient to clean and disassemble the support frame. Only need to separate the support frames in each support hole, and the support holes still remain at the bottom of the outer wall of the curve. The support holes help to improve the energy absorption and release performance of the outer wall of the curve, making it have better shock absorption and buffering effects.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment 1:

[0027] Referring to Figure 1 , a shoe mold structure convenient for 3D printing, including a mold body 10 integrally formed by 3D printing. A curved outer wall 11 is distributed around the periphery of the mold body 10. The bottom of the curved outer wall 11 is used for supporting and contacting the ground, and the curved outer wall 11 forms an elastic support portion. A heel pad 16 is provided on the surface of the mold body 10. A corrugated surface 17 is printed on one side of the heel pad 16. A front cushion block 18 is provided in front of the mold body 10.

[0028] In the above solution, the heel pad 16 can increase the stability of the shoe. Especially when the heel is in a tight state, it helps to prevent the foot from sliding or shaking inside the shoe, ensuring the stability of the foot during walking or running. The heel pad 16 can reduce the fatigue of the foot during running or walking. By providing additional support and cushioning, it reduces the pressure on the foot, making the foot still feel comfortable after long-term activities. The heel pad 16 can prevent the sole part from being rubbed and worn for a long time. During running or other high-intensity exercises, the heel of the shoe is the most easily worn part, and the gasket can effectively reduce this wear and extend the service life of the shoe. The use of the corrugated surface 17 will separate the contact between the insole and the mold body 10 when installing the insole on the mold body 10, reducing the wear inside the mold body 10. At the same time, the gap separated between the corrugated surface 17 and the insole can help the internal air to disperse and circulate, reducing odors.

[0029] Further referring to Figure 1 , the elastic support portion includes an upper opening 12 and a lower opening 13. The upper opening 12 and the lower opening 13 are respectively opened above and below the curved outer wall 11. The curvature of the lower opening 13 bends towards the rear of the mold body 10. The upper opening 12 is distributed between each lower opening 13. Among them, the upper opening 12 is above the lower opening 13, and the upper opening 12 is smaller than the lower opening 13.

[0030] In the above scheme, the elastic support part can effectively provide additional support for the foot, especially during exercise, it can reduce the shaking and instability of the foot, thereby improving the sports performance, and can effectively absorb and disperse the impact force from the ground, thereby reducing the vibration and damage to the foot, and increasing the comfort of wearing. Since the curvature of the lower opening 13 bends toward the rear of the mold body 10, the curved outer wall 11 will deform when it is supported and contacted with the ground, thereby improving the support effect. At the same time, the upper opening 12 is used to absorb part of the deformation effect of the lower opening 13, further improving the support effect and improving the comfort of use. The combination of the lower opening 13 and the upper opening 12 can also accelerate the deformation reset of the curved outer wall 11.

[0031] Further references Figure 1 The curved outer wall 11 gradually narrows forward from the rear of the mold body 10. In this way, the larger curved outer wall 11 at the rear of the mold body 10 can increase the rebound performance of the shoe, so that when walking or running, it can more effectively convert energy into thrust, improve the efficiency of stretching and protecting key parts such as the knee joint. At the same time, the curved outer wall 11 of the mold body 10 that gradually narrows forward, combined with the lower opening 13 and the upper opening 12, can effectively reduce the printing material of the entire mold body 10, and the structure of the mold body 10 is lighter.

[0032] Further references Figure 2 , a fitting block 15 is provided inside the lower opening 13. The fitting block 15 can enhance the supporting effect of the elastic deformation of the lower opening 13. With the improvement of the supporting effect of the elastic deformation, the sole can better maintain its shape when under pressure, provide stronger support and stability for the wearer's feet, prevent the shaking and instability of the feet, and improve sports performance. When the sole is subjected to the pedaling force, it can store energy through its good elastic deformation and release it when the foot leaves the ground, providing the wearer with additional propulsion force and improving the efficiency of walking or running. Enhancing the supporting effect of elastic deformation can better absorb and disperse the impact force from the ground, thereby reducing the impact and damage to the wearer's feet and improving the comfort of walking or sports.

[0033] Embodiment 2:

[0034] refer to Figure 2 and Figure 3 A support frame is provided under the mold body 10, and the support frame is used to stabilize the mold body printing. The support frame includes support holes 14 and a support frame 20. A plurality of support holes 14 are opened at the bottom end of the curved outer wall 11. The support holes 14 support the support frame 20. A support block 21 is provided at the bottom of the support frame 20, and a printing plate 19 is provided at the bottom of the support block 21.

[0035] In the above solution, the support frame 20 is supported in each support hole 14 and fixed on the surface of the printing plate 19 by the support block 21. The support block 21 improves the stability effect of the support frame 20. Multiple support frames 20 are evenly supported in the support holes 14 to stabilize the printing operation of the die body 10. At the same time, after printing is completed, it is convenient to clean and disassemble the support structure. Only need to separate the support frame 20 in each support hole 14, and the support hole 14 still remains at the bottom of the curved outer wall 11. The support hole 14 helps to improve the energy absorption and release performance of the curved outer wall 11, making it have better shock absorption and buffering effects.

[0036] Furthermore, a connecting frame 22 is cross-distributed among the support frames 20. The connecting frame 22 cross-distributed on the support frames 20 can further improve the stability effect of the support frames 20, enhance the lateral support effect of the support frames 20, and prevent the support frames 20 from tilting.

[0037] The specific implementation process of this embodiment is as follows:

[0038] When in use, the elastic support part can effectively provide additional support for the feet. Especially during exercise, it can reduce the shaking and instability of the feet, thereby improving exercise performance. It can effectively absorb and disperse the impact force from the ground, thereby reducing the vibration and damage suffered by the feet and increasing the wearing comfort. Since the curvature of the lower opening 13 bends backward towards the die body 10, when the curved outer wall 11 supported in contact with the ground deforms during backward bending, the support effect is improved. At the same time, the upper opening 12 is used to absorb part of the deformation effect generated by the lower opening 13, further improving the support effect and the use comfort.

[0039] The curved outer wall 11 gradually shrinks forward from the rear of the die body 10. In this way, the larger curved outer wall 11 at the rear of the die body 10 can increase the rebound performance of the shoe, enabling more effective conversion of energy into thrust during walking or running, improving the extension efficiency, and protecting key parts such as the knee joint. At the same time, the curved outer wall 11 of the die body 10 that gradually shrinks forward can effectively reduce the printing material of the overall die body 10, making the structure of the die body 10 lighter.
