Description

Technical Field

[0001] The utility model relates to the field of shoe processing molds, and specifically relates to a three-dimensional ironing mold structure for the collar. Background Art

[0002] The three-dimensional ironing mold for shoe production is a mold dedicated to the three-dimensional ironing process of the shoe upper. This kind of mold is usually used in the production process of sports shoes, casual shoes and other types of shoes, especially in the collar part of the shoe upper, that is, the part around the wearer's ankle, for three-dimensional ironing to increase the beauty and comfort of the shoes.

[0003] Generally, the arc supports inside the existing three-dimensional ironing molds for collars have the same arc and cannot be adjusted. At this time, many defects will occur. For example, the non-adjustable arc means that the mold can only be used to produce shoe uppers with a specific arc or shape, which limits the diversity of the production line and the ability to quickly respond to market demands. If the market demand changes or different styles of shoes need to be produced, the entire set of molds may need to be replaced, which increases the production cost and time. Moreover, if shoe uppers with different arcs need to be produced, multiple sets of molds with different arcs may need to be prepared, which increases the inventory cost and the complexity of maintenance. At the same time, frequent mold replacement may also increase the risk of mechanical failures. In addition, it will also increase the cost of the mold. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a three-dimensional ironing mold structure for the collar to solve the technical problem of poor adaptability of the traditional three-dimensional ironing mold for the collar.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A three-dimensional ironing mold structure for the collar, including a lower mold. An inner lower mold groove is provided inside the lower mold. A deformation groove is provided on the inner wall of the lower mold groove. A limiting piece is arranged outside the deformation groove. A forming mechanism is clamped and slidably arranged inside the lower mold groove. The forming mechanism includes a deformation plate. A card is arranged on the top of the deformation plate. The deformation plate is clamped and slidably arranged in the deformation groove. The card abuts against the limiting piece, and the card and the limiting piece are used to limit the deformation amount of the deformation plate.

[0006] By adopting the above technical scheme, through the design of the deformation groove and the deformation plate, the shape of the collar can be flexibly adjusted to meet the production requirements of different styles of shoes.

[0007] Further, an adjusting mechanism is arranged at the bottom of the forming mechanism. The adjusting mechanism includes a movable groove. A top rod is rotatably connected inside the movable groove.

[0008] By adopting the above technical scheme, the existence of the adjusting mechanism makes the arc adjustment of the forming mechanism more convenient and improves the production efficiency.

[0009] Furthermore, a chute is provided on one side of the inner wall of the movable slot, and the chute penetrates through to the outer surface of the lower mold.

[0010] By adopting the above technical solution, the design of the chute provides space for the movement of the sliding rod, facilitating adjustment by the operator from the outside.

[0011] Furthermore, a sliding rod is slidably connected inside the chute, and a wedge-shaped top block is provided on one side of the sliding rod close to the ejector rod.

[0012] By adopting the above technical solution, through the cooperation of the sliding rod and the wedge-shaped top block, the ejector rod can be precisely lifted, thereby precisely adjusting the curvature of the deformed plate.

[0013] Furthermore, the wedge-shaped top block abuts against the ejector rod, and the wedge-shaped top block is used to lift the ejector rod to adjust the curvature of the deformed plate.

[0014] By adopting the above technical solution, stepless adjustment of the ejector rod can be achieved through the above abutting method, meeting various curvature requirements.

[0015] Furthermore, fixing holes are provided on both the top of the chute and the sliding rod, and fixing bolts are threadedly connected inside the fixing holes, and the fixing bolts are used to fix the sliding rod to facilitate fixing the curvature of the deformed plate.

[0016] By adopting the above technical solution, the design of the fixing bolts enables the sliding rod to be firmly fixed after adjustment, ensuring the stability of the production process.

[0017] Furthermore, an upper mold is provided above the forming mechanism, and an upper mold groove is provided at the bottom of the upper mold.

[0018] By adopting the above technical solution, the cooperation of the upper mold and the lower mold enables the collar to be evenly formed when heated and under pressure, improving the product quality.

[0019] Furthermore, the lower mold fits with the upper mold, and the lower mold and the upper mold are placed in an external hot press to hot press the shoe collar.

[0020] By adopting the above technical solution, the lower mold fits with the upper mold, ensuring the sealing of the mold during the hot pressing process and preventing leakage and waste of the hot pressing material.

[0021] Furthermore, the materials of the lower mold and the upper mold are polypropylene, and the material of the deformed plate is a thermoplastic resin material.

[0022] By adopting the above technical solution, the polypropylene material has good heat resistance and mechanical strength, extending the service life of the mold.

[0023] Furthermore, the lower mold groove is adapted to the external shoe collar.

[0024] By adopting the above technical solution, the adapted design ensures that the shoe collar can be closely fitted in the lower mold groove, improving the accuracy and efficiency of molding.

[0025] To sum up, the present utility model mainly has the following beneficial effects:

[0026] 1. The present utility model is provided with a molding mechanism and an adjusting mechanism. By adjusting the position of the sliding rod in the sliding groove, the arc of the deformation plate is changed. The specific operation is that when the arc needs to be adjusted, the sliding rod can be moved so that the wedge-shaped top block on it abuts against the ejector rod. As the sliding rod moves, the wedge-shaped top block will lift or lower the ejector rod, thereby changing the position of the deformation plate in the deformation groove and realizing the adjustment of the arc. At this time, the factory can flexibly adjust the arc of the shoe upper according to production requirements or design specifications. This flexibility enables the mold to adapt to various shoe types and production requirements, thus improving the diversity and adaptability of the production line. Moreover, the adjustment process is relatively simple and fast. Once the operator is familiar with the operation process, the arc can be adjusted within a short time. This high efficiency helps to improve production efficiency and the ability to respond to market changes.

[0027] 2. The present utility model is provided with fixing holes and fixing bolts. After the angle of the deformation plate is adjusted, the sliding rod is fixed at the required position through the fixing holes and fixing bolts, ensuring the stability of the deformation plate during the production process. This stability is crucial for maintaining the consistency of production quality. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0034] Next, according to the overall structure of the present utility model, its embodiments will be described.

[0035] Embodiment 1:

[0036] A three-dimensional ironing die structure for the collar, as Figures 1-4 shown, includes a lower die 1. An inner die groove 3 is opened inside the lower die 1. A deformation groove 6 is opened on the inner wall of the die groove 3. A limiting piece 7 is arranged outside the deformation groove 6. A forming mechanism 5 is clamped and slidably arranged inside the die groove 3. The forming mechanism 5 includes a deformation plate 501. A card 502 is arranged on the top of the deformation plate 501. The deformation plate 501 is clamped and slidably arranged in the deformation groove 6. The card 502 abuts against the limiting piece 7, and the card and the limiting piece 7 are used to limit the deformation amount of the deformation plate 501. By opening the die groove 3 and the deformation groove 6 inside the lower die 1, and configuring the forming mechanism 5 with the limiting piece 7, the flexible clamping and sliding of the deformation plate 501 can be realized. The cooperation between the card 502 and the limiting piece 7 effectively limits the deformation amount of the deformation plate 501, ensuring the forming accuracy and the consistency of the product.

[0037] Refer to Figure 2 、 Figure 3 , a regulating mechanism 4 is arranged at the bottom of the forming mechanism 5. The regulating mechanism 4 includes a movable groove 401. A top rod 402 is rotatably connected inside the movable groove 401. The regulating mechanism 4 arranged at the bottom of the forming mechanism 5 provides convenience for adjusting the radian of the deformation plate 501 through the movable groove 401 and the rotatably connected top rod 402, increasing the flexibility and adaptability of the die.

[0038] Refer to Figure 2 、 Figure 3 , a sliding groove 403 is opened on one side of the inner wall of the movable groove 401, and the sliding groove 403 penetrates to the outer surface of the lower die 1. The sliding groove 403 opened on one side of the inner wall of the movable groove 401 penetrates to the outer surface of the lower die 1, facilitating the operation of the sliding rod 404 from the outside, simplifying the adjustment process and improving the operation efficiency.

[0039] Refer to Figure 2 、 Figure 3 , a sliding rod 404 is slidably connected inside the sliding groove 403. A wedge-shaped top block 405 is arranged on one side of the sliding rod 404 close to the top rod 402. By using the sliding rod 404 and the wedge-shaped top block 405 slidably connected inside the sliding groove 403, the precise jacking of the top rod 402 can be realized, and then the radian of the deformation plate 501 can be finely adjusted, improving the forming quality of the product.

[0040] Refer to Figure 2 and Figure 3 where the wedge-shaped top block 405 abuts against the ejector rod 402. The wedge-shaped top block 405 is used to lift the ejector rod 402 to adjust the arc of the deformation plate 501. By the abutment of the wedge-shaped top block 405 and the ejector rod 402, fine adjustment of the arc of the deformation plate 501 can be achieved. The design of the wedge-shaped top block 405 allows the operator to precisely change the height of the ejector rod 402 by controlling its position, thereby adjusting the shape of the deformation plate 501. This precise adjustment ability is crucial for ensuring the forming accuracy of the neckline three-dimensional ironing mold, which can help produce shoes' necklines that meet the design requirements and improve product quality.

[0041] Embodiment 2:

[0042] Refer to Figure 2 and Figure 3 where fixing holes 406 are provided at the top of the chute 403 and on the slide bar 404. A fixing bolt 407 is threadedly connected inside the fixing hole 406, and the fixing bolt 407 is used to fix the slide bar 404 to fix the arc of the deformation plate 501. Through the cooperation of the fixing hole 406 and the fixing bolt 407, it can be ensured that the slide bar 404 can be firmly fixed after being adjusted to a predetermined position. This fixing method effectively prevents the slide bar 404 from shifting due to vibration or other external forces during the production process, thereby ensuring the stability and consistency of the arc of the deformation plate 501. The stable arc of the deformation plate 501 is a key factor in ensuring the forming quality of the neckline, which helps improve the qualification rate and reliability of the product.

[0043] Refer to Figure 2 and Figure 3 where an upper mold 2 is provided above the forming mechanism 5. An upper mold groove is provided at the bottom of the upper mold 2. The close cooperation between the upper mold 2 and the forming mechanism 5 ensures uniform stress on the neckline during the hot pressing process. The existence of the upper mold groove enables the upper mold 2 to accurately align with the forming mechanism 5 in the lower mold 1, thereby ensuring that the neckline material can accurately fill the mold space during hot pressing and obtain the expected three-dimensional shape. This design significantly improves the forming effect of the neckline, making it more in line with the design requirements and having better three-dimensional sense and aesthetics.

[0044] Refer to Figure 1 and Figure 2 and Figure 3, the lower mold 1 fits with the upper mold 2, and the lower mold 1 and the upper mold 2 are placed in an external hot press to hot press the shoe collar. The lower mold 1 and the upper mold 2 fit with each other. The design of the fitting molds means that the upper mold 2 and the lower mold 1 can be accurately aligned when closed, ensuring that the collar material can be evenly stressed and accurately fill the mold space during the hot pressing process. This alignment accuracy is crucial for producing shoe collars with precise shapes and consistent sizes, and helps to increase production.

[0045] See Figure 1 、 Figure 2 、 Figure 3 , the materials of the lower mold 1 and the upper mold 2 are polypropylene, and the material of the deformation plate 501 is a thermoplastic resin material. The polypropylene material improves the heat resistance and mechanical strength of the mold, while the thermoplastic resin material ensures the good deformation recovery ability of the deformation plate 501.

[0046] See Figure 2 、 Figure 3 、 Figure 4 , the lower mold groove 3 is adapted to the external shoe collar. Therefore, the lower mold groove 3 ensures that the shoe collar can fit tightly in the lower mold groove 3, improving the accuracy and efficiency of molding, and at the same time reducing errors and waste rates during the production process.

[0047] The implementation principle of the present utility model is as follows: First, it is necessary to ensure that the lower mold 1 and the upper mold 2 are in a clean state, without debris or residues, and check whether components such as the deformation plate 501, the card 502, the limit piece 7, and the adjustment mechanism 4 are intact and move freely. Then, according to the curvature of the shoe collar to be produced, adjust the curvature of the deformation plate 501 through the adjustment mechanism 4. At this time, the position of the sliding rod 404 in the sliding groove 403 can be moved so that the wedge-shaped top block 405 abuts against the top rod 402, thereby lifting or lowering the top rod 402 and changing the position of the deformation plate 501 in the deformation groove 6. After that, after observing and adjusting to the required curvature, use the fixing bolt 407 to fix the sliding rod 404 at the top of the sliding groove 403 to ensure that the curvature of the deformation plate 501 remains stable during the hot pressing process;

[0048] During the processing, place the part of the shoe collar to be processed in the lower mold groove 3, ensure that the collar part fits tightly with the deformation plate 501, and note that the position of the collar should be correctly aligned with the deformation groove 6 so as to form the required three-dimensional shape during the hot pressing process. Gently close the upper mold 2 on the lower mold 1 to ensure that the upper mold groove is completely aligned with the lower mold groove 3. At this time, the upper mold 2 and the lower mold 1 should be tightly closed to form a complete hot pressing space. Then, place the entire mold structure in an external hot press, set appropriate hot pressing temperature and time according to the material and thickness of the shoe material, start the hot press, heat and press the mold, so that the shoe collar part fits tightly with the deformation plate 501 under the action of heat and pressure to form the required three-dimensional shape.
