Description
Technical Field
[0001] The utility model relates to the technical field of shoe production and processing, in particular to a shoe molding mold. Background Art
[0002] Shoe upper fitting patches are a common footwear manufacturing process, mainly used to enhance the aesthetics, durability and functionality of the shoe upper. Fitting patches can be made of various materials, such as fabric, leather, synthetic materials, etc. The choice of these materials depends on the design purpose and use environment of the shoe. In the process, in order to improve the protection of the shoe to the ankle and improve the practicality of the shoe, most of the fitting patches are sewn at the inversion position of the shoe.
[0003] At present, many shoemaking processes still rely on manual operation in the process of laminating patches. Workers need to manually align the laminating patches with the uppers and place them together, and then use sewing machines to sew them carefully. However, this manual laminating method has many challenges. Due to the different shapes of laminating patches, manual operation cannot ensure that each laminating can be accurate and correct, which leads to increased instability in product quality. In addition, manual laminating has high technical requirements for workers and is difficult to operate. This not only affects production efficiency, but may also cause a series of quality problems due to human factors. Therefore, the shoemaking industry urgently needs a more efficient and precise laminating mold to replace the traditional manual laminating method to improve product quality and production efficiency. Utility Model Content
[0004] Based on this, the purpose of the utility model is to provide a shoe molding mold to solve the many challenges of manual bonding. Due to the different shapes of bonding pieces, manual operation is difficult to ensure that each bonding can be achieved accurately and without error.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a shoe forming mold, comprising a sewing machine, a rotating plate, a shoe upper and a bonding sheet, a clamping mechanism is arranged on the top of the rotating plate, the clamping mechanism comprises a fixed seat, a movable rod is rotatably connected to the fixed seat, a pressing mold is arranged at one end of the movable rod, a hollow groove is opened on the pressing mold, and the hollow groove is opposite to the bonding sheet.
[0006] By adopting the above technical solution, this precise alignment not only simplifies the subsequent sewing process, but more importantly, it significantly improves the sewing processing accuracy of the bonding sheet. Since the bonding sheet has been accurately positioned before sewing, the sewing machine can sew it more accurately, thereby avoiding sewing errors or quality problems caused by position deviations.
[0007] Furthermore, the pressing mold is in contact with the shoe upper, and the empty groove is matched with the bonding sheet.
[0008] By adopting the above technical solution, firstly, the abutment between the pressing mold and the upper ensures stability and precision during the fitting process. This close contact enables the fitting piece to maintain the correct position before being sewn onto the upper, avoiding any possible displacement or misalignment, thereby significantly improving the accuracy of the fitting. This precise fit and close abutment design not only simplifies the fitting process, but also reduces the need for manual operation.
[0009] Furthermore, tension springs are provided on both sides of the movable rod, and the two tension springs are arranged in a mirror image.
[0010] By adopting the above technical solution, since the tension springs are arranged in a mirror image, they provide balanced tension for the movable rod.

[0011] Furthermore, the other end of the movable rod is fixedly connected with a pressing block, and the pressing block is arranged in an inclined structure.
[0012] By adopting the above technical solution, since the pressing block and the movable rod are fixedly connected, the force applied by the operator to the pressing block can be directly and efficiently transmitted to the movable rod, which is conducive to enabling the movable rod to overcome the force of the tension spring and rotate.
[0013] Furthermore, the pressing mold is detachably connected to the movable rod via bolts, and the movable rod and the pressing mold are both made of stainless steel.
[0014] By adopting the above technical solution and using bolts as connecting parts, the pressing mold and the movable rod can be easily disassembled and assembled, which not only facilitates the maintenance, cleaning and replacement of the mold, but also greatly improves the flexibility and work efficiency of the production line. When the mold needs to be replaced or repaired, the operator can quickly complete the disassembly and reassembly, reducing downtime.
[0015] Furthermore, a plurality of the clamping mechanisms are provided, and the plurality of the clamping mechanisms are arranged in an equidistant ring shape along the central axis of the rotating plate.
[0016] By adopting the above technical solution, multiple workstations allow multiple uppers to be processed simultaneously, thereby significantly increasing production volume. Each workstation can operate independently without interfering with each other, allowing the entire production process to proceed in parallel, greatly reducing production cycle and waiting time.
[0017] Furthermore, a plurality of spring clamps are provided on the outer side of the shoe upper, and the shoe upper is connected to the rotating plate by means of the spring clamps.
[0018] By adopting the above technical solution, the spring clamp has the characteristics of quick clamping and releasing, so that the upper can be quickly and accurately fixed on the turn plate. This quick positioning not only improves production efficiency, but also helps to ensure the precise alignment of the bonding sheet and the upper.
[0019] Furthermore, a movable plate is provided at the bottom end of the rotating plate, and the rotating plate is slidably connected to the movable plate via a second transmission mechanism.
[0020] By adopting the above technical solution, by slidingly connecting the rotating plate and the movable plate, the relative position between the two can be ensured to be stable, and the deviation caused by vibration or external force can be reduced. This stability is crucial to ensure the accuracy of shoe upper fitting and sewing. The design of the movable plate enables the rotating plate to be flexibly adjusted according to different production needs.
[0021] Furthermore, a support plate is provided at the bottom end of the movable plate, and the movable plate is slidably connected to the support plate via a first transmission mechanism.
[0022] By adopting the above technical solution, the support plate provides a firm support for the movable plate, ensuring its stability and reliability during the working process. Such stability is crucial to ensure the accuracy of upper fitting and sewing, and helps to improve product quality.
[0023] Furthermore, the rotating plate is arranged in a rotatable structure, and the first transmission mechanism and the second transmission mechanism are both screw motors.
[0024] By adopting the above technical solution, the rotatable structure of the turntable enables the equipment to easily adapt to the processing requirements of different workstations and directions.

DETAILED DESCRIPTION
[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0034] The following describes an embodiment of the utility model based on its overall structure.
[0035] Embodiment 1:
[0036] A shoe molding mold, such as Figure 1-Figure 4As shown, it includes a sewing machine 1, a rotating plate 203, an upper 4 and a bonding sheet 6. A clamping mechanism 3 is arranged on the top of the rotating plate 203. The clamping mechanism 3 includes a fixed seat 301. A movable rod 302 is rotatably connected to the fixed seat 301. A pressing mold 305 is arranged at one end of the movable rod 302. An empty slot 307 is opened on the pressing mold 305. The empty slot 307 is opposite to the bonding sheet 6. This precise alignment not only simplifies the subsequent sewing process, but more importantly, it significantly improves the sewing processing accuracy of the bonding sheet 6. Since the bonding sheet 6 has been accurately positioned before sewing, the sewing machine 1 can sew it more accurately, thereby avoiding sewing errors or quality problems caused by position deviation. Placing the bonding sheet 6 inside the empty slot 307 and completing the precise alignment with the upper 4 is a key step in improving the sewing processing accuracy of the bonding sheet 6. It lays a solid foundation for the subsequent sewing process and ensures the quality and accuracy of the final product.
[0037] See also Figure 2 , Figure 3 , Figure 4 The pressing mold 305 is in contact with the upper 4, and the empty groove 307 is matched with the bonding sheet 6. Firstly, the contact between the pressing mold 305 and the upper 4 ensures stability and accuracy during the bonding process. This close contact enables the bonding sheet 6 to maintain the correct position before being sewn onto the upper 4, avoiding any possible displacement or misalignment, thereby significantly improving the accuracy of the bonding. This precise fit and close contact design not only simplifies the bonding process and reduces the need for manual operation, but also greatly improves production efficiency. At the same time, it also eliminates the possibility of position deviation and quality inconsistency caused by manual bonding, thereby significantly improving the overall quality of the shoes.
[0038] Embodiment 2:
[0039] See also Figure 3 , Figure 4 , tension springs 304 are provided on both sides of the movable rod 302, and the two tension springs 304 are arranged in a mirror image. Since the tension springs 304 are arranged in a mirror image, they provide balanced tension for the movable rod 302. This design ensures the stability and balance of the movable rod 302 during movement, and prevents it from being offset or tilted due to uneven force. The elastic properties of the tension spring 304 enable it to store potential energy when stretched and generate a strong rebound force when released. This rebound force directly acts on the movable rod 302 and is then transmitted to the pressing mold 305, providing it with a solid pressing force. This pressing force ensures that the pressing mold 305 can fit tightly on the vamp 4 to achieve precise clamping.
[0040] See also Figure 2 , Figure 3 , Figure 4The other end of the movable rod 302 is fixedly connected to a pressing block 303, and the pressing block 303 is arranged in an inclined structure. Since the pressing block 303 is fixedly connected to the movable rod 302, the force applied by the operator to the pressing block 303 can be directly and efficiently transmitted to the movable rod 302, which is conducive to the movable rod 302 to overcome the force of the tension spring 304 and rotate. At the same time, the pressing mold 305 eliminates the pressing force on the shoe upper 4, thereby improving the ease of use of the clamping mechanism 3. This force transmission efficiency ensures that the pressing mold 305 can respond to the operator's actions quickly and accurately.
[0041] See also Figure 3 , Figure 4 The pressing mold 305 is detachably connected to the movable rod 302 by bolts 306. The movable rod 302 and the pressing mold 305 are both made of stainless steel. The bolts 306 are used as connecting parts, so that the pressing mold 305 and the movable rod 302 can be easily disassembled and assembled, which not only facilitates the maintenance, cleaning and replacement of the mold, but also greatly improves the flexibility and work efficiency of the production line. When the mold needs to be replaced or repaired, the operator can quickly complete the disassembly and reassembly, reducing downtime. The stainless steel material has excellent corrosion resistance and mechanical strength, and can effectively resist chemical corrosion and physical wear in the working environment, which means that the movable rod 302 and the pressing mold 305 can maintain their structural integrity and functionality during long-term use, thereby extending the service life of the entire mold.
[0042] See also Figure 2 , Figure 3 , Figure 4 There are multiple clamping mechanisms 3, and the multiple clamping mechanisms 3 are arranged in an equidistant ring along the central axis of the rotating plate 203. The multiple workstations allow multiple uppers to be processed simultaneously, thereby significantly increasing the production volume. Each workstation can operate independently without interfering with each other, so that the entire production process can be carried out in parallel, greatly reducing the production cycle and waiting time. Each workstation is equipped with the same clamping mechanism 3 and process parameters, ensuring that each upper can be consistently and accurately processed during the bonding and sewing process. This standardized operation helps to reduce human errors and improve product consistency and quality.
[0043] See also Figure 1 , Figure 2 , Figure 4A plurality of spring clamps 5 are arranged on the outer side of the upper 4, and the upper 4 is connected to the rotating plate 203 by means of the spring clamps 5. The spring clamps 5 have the characteristics of quick clamping and releasing, so that the upper 4 can be quickly and accurately fixed on the rotating plate 203. This quick positioning not only improves the production efficiency, but also helps to ensure the precise alignment of the bonding sheet 6 and the upper 4. The design of the spring clamps 5 has a certain degree of elasticity and can adapt to uppers 4 of different thicknesses and materials. This adaptability ensures that no matter how the specifications of the upper 4 change, a stable snap-on connection can be achieved through the spring clamps 5.
[0044] See also Figure 1 , Figure 2 A movable plate 202 is provided at the bottom end of the rotating plate 203, and the rotating plate 203 is slidably connected to the movable plate 202 through a second transmission mechanism 205. By slidably connecting the rotating plate 203 and the movable plate 202, the relative position between the two can be ensured to be stable, and the deviation caused by vibration or external force can be reduced. This stability is very important for ensuring the accuracy of shoe upper fitting and sewing. The design of the movable plate 202 enables the rotating plate 203 to be flexibly adjusted according to different production requirements. Through the drive of the second transmission mechanism 205, the relative position between the rotating plate 203 and the movable plate 202 can be easily adjusted to adapt to shoe uppers of different sizes or styles.
[0045] See also Figure 1 , Figure 2 A support plate 201 is provided at the bottom end of the movable plate 202. The movable plate 202 is slidably connected to the support plate 201 through a first transmission mechanism 204. The support plate 201 provides a firm support for the movable plate 202 to ensure its stability and reliability during operation. Such stability is essential for ensuring the accuracy of upper fitting and sewing, and helps to improve product quality. Driven by the first transmission mechanism 204, the movable plate 202 can slide on the support plate 201 to achieve flexible position adjustment. This design enables the equipment to adapt to uppers of different sizes and styles, thereby improving the flexibility and adaptability of the production line.
[0046] See also Figure 1 , Figure 2 The rotating plate 203 is arranged in a rotatable structure, and the first transmission mechanism 204 and the second transmission mechanism 205 are both screw motors. The rotatable structure of the rotating plate 203 enables the equipment to easily adapt to the processing requirements of different workstations and directions. This flexibility is essential for handling complex upper fitting and sewing tasks, and helps to improve production efficiency and quality. The screw motor as the first transmission mechanism 204 and the second transmission mechanism 205 provides high-precision position and motion control, which enables the sliding and rotation of the movable plate 202 and the rotating plate 203 to achieve more precise adjustment, meeting the precise alignment requirements during the upper fitting and sewing process.
[0047] The implementation principle of the utility model is as follows: first, the vamp 4 is clamped and fixed on the rotating plate 203 by using the spring clamp 5, and then the pressing mold 305 is pressed to make the pressing mold 305 contact with the vamp 4, and then the bonding sheet 6 is placed inside the empty groove 307 to complete the precise alignment of the bonding sheet 6 and the vamp 4, and then the rotating plate 203 is rotated to make the station rotate to the sewing area of the sewing machine 1, and then the control center controls the first transmission mechanism 204, the second transmission mechanism 205 and the sewing machine 1 to cooperate to complete the precise sewing of the bonding sheet 6, which is conducive to improving the sewing processing accuracy of the bonding sheet 6;
[0048] Through the cooperation between the first transmission mechanism 204 and the second transmission mechanism 205, the sewing position of the bonding sheet 6 of the sewing machine 1 is changed, the sewing automation of the bonding sheet 6 is improved, and the sewing efficiency is improved.
