[0002] Footwear materials refer to the various raw materials used in the manufacture of footwear products, encompassing uppers, soles, linings, and accessories. Common upper materials include natural leather (such as cowhide and sheepskin), synthetic leather, textiles (such as canvas and mesh), and synthetic fibers (such as flyknit fabric), balancing aesthetics and breathability. Soles are often made of rubber, EVA (ethylene-vinyl acetate copolymer), PU (polyurethane), or TPR (thermoplastic rubber), providing abrasion resistance, cushioning, and slip resistance. Linings commonly use soft and breathable foam, fleece, or antibacterial linings to enhance comfort. Additionally, shoelaces, metal eyelets, adhesives, and other accessories also fall under the category of footwear materials.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1-5This utility model provides an embodiment of a multi-functional hot pressing molding equipment for shoe material production, including a hot pressing table 1. A lower hot pressing mold 2 is fixedly connected to the middle of the upper end face of the hot pressing table 1. A cooling water circulation pipe 3 is fixedly connected to the middle of the interior of the lower hot pressing mold 2. The cooling water circulation pipe 3 extends out of the end face of the lower hot pressing mold 2 at both ends and is connected to a connecting pipe 4. After extending out of the end face of the lower hot pressing mold 2 at both ends of the cooling water circulation pipe 3, an external threaded pipe 301 is fixedly connected to each end. The outer wall of the connecting pipe 4 is adjacent to the cooling water circulation pipe 3. A clamping ring 401 is fixedly connected, and an internally threaded pipe 402 is rotatably connected to the outside of the clamping ring 401. The connecting pipe 4 and the cooling water circulation pipe 3 are connected and fixed by the internally threaded pipe 402 being fitted onto the outside of the externally threaded pipe 301. The ends of both connecting pipes 4 away from the cooling water circulation pipe 3 are connected to an external cooling device, allowing the two connecting pipes 4 to be separated from the cooling water circulation pipe 3. Cooling water is circulated into the cooling water circulation pipe 3 through the external cooling device, so that the cooling water circulates through the lower hot press mold 2 after hot pressing. The cooling process allows the shoe material to cool down quickly after hot pressing, making it easier for personnel to handle. A first heating rod 203 is fixedly connected to both the front and rear ends of the center of the lower hot pressing mold 2. Guide support columns 102 are fixedly connected to both the front and rear ends of the center of the upper surface of the hot pressing table 1. A support plate 5 is fixedly connected to the upper end of the four guide support columns 102. A hydraulic rod 501 is fixedly connected to the center of the upper end of the support plate 5. A lifting plate 6 is connected to the upper end of the four guide support columns 102. An upper hot pressing mold 602 is fixedly connected to the center of the lower end of the lifting plate 6. The front and rear ends of the middle part of the device 602 are fixedly connected to the second heating rod 603. The lower end of the extension end of the hydraulic rod 501 passes through the support plate 5 and is fixedly connected to the middle of the upper end face of the lifting plate 6. By placing the shoe material on the upper end of the lower hot pressing mold 2, the hydraulic rod 501 drives the lifting plate 6 to descend, thereby causing the lifting plate 6 to drive the upper hot pressing mold 602 to descend and close with the lower hot pressing mold 2 to hot press the shoe material. The first heating rod 203 and the second heating rod 603 respectively heat the upper hot pressing mold 602 and the lower hot pressing mold 2 during hot pressing.

[0025] Please see Figure 2 The hot press table 1 has internally threaded positioning pins 101 fixedly connected to both the front and rear ends of the middle side of the upper end face. The lower hot press mold 2 has positioning slots 201 set at both the front and rear ends of the middle side of the lower end face. The four internally threaded positioning pins 101 are respectively inserted into the four positioning slots 201 on the lower end face of the lower hot press mold 2. The lower hot press mold 2 is fixed to the upper end face of the hot press table 1 by four bolts 202 passing through the upper end face of the lower hot press mold 2 and being inserted into the four internally threaded positioning pins 101. By removing multiple bolts 202, the lower hot press mold 2 can be separated from the hot press table 1 upwards, which is convenient for replacing the lower hot press mold 2.

[0026] Please see Figure 2 and Figure 3 The front and rear ends of both sides of the middle of the lifting plate 6 are fixedly connected to guide tubes 601. The upper ends of the middle of the four guide support columns 102 pass through the interior of the four guide tubes 601 respectively. When the lifting plate 6 is raised or lowered, it is guided by sliding along the guide support columns 102 through the guide tubes 601 to ensure the stability of the lifting plate 6.

[0027] Working principle: During use, the shoe material to be processed is placed on the upper surface of the lower hot press mold 2. The hydraulic rod 501 is activated to push the lifting plate 6 smoothly downward along the guide support column 102, causing the upper hot press mold 602 to press against the lower hot press mold 2. At this time, the first heating rod 203 and the second heating rod 603 heat up simultaneously, so that the mold quickly reaches the set temperature to complete the hot pressing molding. After molding, the external cooling device is turned on, and the cooling water enters the cooling water circulation pipe 3 through the connecting pipe 4 for circulation, accelerating the cooling process of the lower hot press mold 2, so that the shoe material drops to the workable temperature in a short time. When it is necessary to replace the mold, loosen the internal threaded pipe 402 to disconnect the cooling pipe, and remove the bolt 202 to remove the lower hot press mold 2 from the internal threaded positioning column 101 for replacement.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
