[0002] In the existing manufacturing process of shoes with holes (such as hole shoes), the injection molding method is usually used. The specific manufacturing steps include preparing the mold base, mold core and related components, and then completing the product production through processes such as mold closing, injection molding and demoulding. However, in actual production, there are several major problems: 1. Die base wear problem: The contact surface between the die core and the upper or lower die will gradually wear out during long-term die opening and closing operations due to similar material hardness. This wear will cause gaps between the two parts, causing the molten material to overflow from these gaps, forming burrs. Burrs not only affect the appearance quality of the finished product, but also increase the cost of subsequent processing procedures.

[0003] 2. Die base life problem: Due to wear and tear, the service life of the die base is short, and frequent replacement of the die base will increase production costs.

[0004] 3. Manual processing of burrs: Manual processing of burrs is inefficient and easily leads to defective finished products, further increasing production costs and difficulty in quality control.

[0005] In response to the problems existing in the above-mentioned prior art, the present invention aims to provide a method for manufacturing shoes with holes, which can effectively prevent burrs from being generated between mold bases due to wear, improve the appearance quality and production efficiency of the finished product, extend the service life of the mold base, reduce production costs, and can flexibly adapt to the design of holes of different shapes and sizes.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0028] In the existing manufacturing process of shoes with holes (such as hole shoes), the injection molding method is usually used. The specific manufacturing steps include preparing the mold base, mold core and related components, and then completing the product production through processes such as mold closing, injection molding and demoulding. However, in actual production, there are several major problems: 1. Die base wear problem: The contact surface between the die core and the upper or lower die will gradually wear out during long-term die opening and closing operations due to similar material hardness. This wear will cause gaps between the two parts, causing the molten material to overflow from these gaps, forming burrs. Burrs not only affect the appearance quality of the finished product, but also increase the cost of subsequent processing procedures.

[0029] 2. Die base life problem: Due to wear and tear, the service life of the die base is short, and frequent replacement of the die base will increase production costs.

[0030] 3. Manual processing of burrs: Manual processing of burrs is inefficient and easily leads to defective finished products, further increasing production costs and difficulty in quality control.

[0031] In response to the problems existing in the above-mentioned prior art, the present invention aims to provide a method for manufacturing shoes with holes, which can effectively prevent burrs from being generated between mold bases due to wear, improve the appearance quality and production efficiency of the finished product, extend the service life of the mold base, reduce production costs, and can flexibly adapt to the design of holes of different shapes and sizes.

[0032] For this reason, Figures 1 to 6 As shown, the method for manufacturing shoes with holes proposed by the present invention comprises the following steps performed in sequence: S100, preparing parts: preparing a mold base 100, a mold core 200 and an elastic positioning block 300, wherein the mold base 100 is provided with a shoe-shaped cavity wall 101, the mold core 200 is provided with a shoe-shaped portion 220 matching the shape of the shoe-shaped cavity wall 101, and the outer peripheral wall of the elastic positioning block 300 matches the shape of the hole of the shoe; S200, mold closing and positioning: after the parts are prepared, the mold core 200 and the elastic positioning block 300 are placed in the mold base 100, the surface of the shoe-shaped portion 220 is separated from the cavity wall of the shoe-shaped cavity wall 101, and the two ends of the elastic positioning block 300 elastically press the shoe-shaped portion 220 and the shoe-shaped cavity wall 101 respectively; S300, injection molding: After the mold is closed and positioned, the molten plastic raw material is injected into the space between the shoe-shaped portion 220 and the shoe-shaped cavity wall 101. After the plastic raw material is fixed and formed, the formed plastic raw material is separated from the mold base 100.

[0033] It should be noted that by preparing the mold base 100, the mold core 200 and the elastic positioning block 300, the characteristics of the elastic positioning block 300 are used to achieve precise positioning between the mold core 200 and the mold base 100, which effectively prevents the problem of the mold core 200 being suspended during mold closing and positioning due to wear of the mold base 100, ensuring the close fit between the mold core 200 and the mold base 100 during the injection molding process, and the elastic positioning block 300 can be closely matched with the mold base 100 and the mold core 200 when the mold base 100 is closed to form a closed area, ensuring that the plastic raw material does not overflow into the non-molding area, thereby effectively preventing burrs from appearing in the holes of the finished shoes; in addition, the elastic characteristics of the elastic positioning block 300 help to absorb the impact force during the opening and closing mold positioning process, reduce the wear of the various components of the mold base 100, and improve the stability and service life of the mold base 100, which not only improves the appearance quality and production efficiency of the finished product, but also extends the service life of the mold base 100, reduces the production cost, and can flexibly adapt to the design of holes of different shapes and sizes.

[0034] In some embodiments of the present invention, Figure 3 As shown, in the preparation of parts, the outer wall of the shoe-shaped portion 220 is processed to form a mounting groove 201, and the elastic positioning block 300 is embedded and installed in the mounting groove 201, which significantly improves the convenience of installation and maintenance of the mold, making the installation and removal of the elastic positioning block 300 more convenient, and is convenient for rapid replacement when worn or damaged, reducing downtime and maintenance costs. At the same time, the design of the mounting groove 201 ensures the precise installation position of the elastic positioning block 300, improves the precision and stability of the mold, thereby ensuring the close fit of the various components during the injection molding process, further preventing the overflow of the injection molding material, and avoiding the burr problem on the edge of the finished product. In some manufacturing applications, the core 200 is hollowed out at the position corresponding to the hole of the shoe, and then the elastic positioning block 300 of the corresponding shape is manufactured and embedded in the core 200 and fixed to prevent the elastic positioning block 300 from loosening. Optionally, the core 200 after being embedded is subjected to overall precision machining by a CNC machine tool. Optionally, the elastic positioning block 300 is a plastic steel part with superior properties of high hardness, high resilience and corrosion resistance.

[0035] Further, refer to Figures 2 to 4In some embodiments of the present invention, in the preparation of parts, the shoe-shaped cavity wall 101 is provided with an alignment block 111, and the alignment block 111 corresponds to the position of the elastic positioning block 300. After the mold is closed and positioned, the alignment block 111 and the elastic positioning block 300 are pressed and matched. The sealing and stability of the mold are further improved. When the mold base 100 and the mold core 200 are closed, the elastic positioning block 300 elastically presses against the alignment block 111 to form a tight sealing area, which effectively prevents the injection material from overflowing from the gap during the molding process and avoids the burr problem on the edge of the finished product. It not only improves the appearance quality and consistency of the finished product, but also enhances the stability of the mold during the opening and closing process, reduces the wear caused by vibration and displacement, and extends the service life of the mold. In addition, the cooperation between the alignment block 111 and the elastic positioning block 300 ensures precise positioning during mold closing, further improves the accuracy and reliability of the mold, thereby reducing production costs and improving production efficiency. In some embodiments, the alignment block 111 is integrally connected to the mold base 100, for example, the alignment block 111 is machined on the mold base 100 by cutting using a CNC machine tool. In some embodiments, the alignment block 111 is elastic, the mold base 100 is a rigid component, and the alignment block 111 is injection molded on the mold base 100. In some embodiments, similar to the elastic positioning block 300, the alignment block 111 is separately provided with the mold base 100 and connected by embedding. Specifically, the alignment block 111 is embedded in the shoe-shaped cavity wall 101, and the material of the alignment block 111 is different from that of the elastic positioning block 300, ensuring that the two can form a specified closed area after being pressed together, thereby forming a hole of a preset size and shape. Optionally, one of the alignment block 111 and the elastic positioning block 300 is made of high-hardness, high-rebound and corrosion-resistant plastic steel material, which can form a double elastic seal when the mold is closed, ensuring that the injection material will not overflow from the gap during the molding process, effectively avoiding the burr problem on the edge of the finished product. This double-end elastic pressing design not only improves the sealing effect of the mold, but also enhances the wear resistance of each component of the mold and extends the service life of the mold.

[0036] Refer to Figures 2 to 4In some embodiments of the present invention, the mold base 100 includes an upper mold 110 and a lower mold 120, and the upper mold 110 and the lower mold 120 are respectively covered and matched with the two sides of the mold core 200. Through the design of the upper mold 110 and the lower mold 120, the stability and sealing of the mold core 200 during the injection molding process are ensured, the quality of the finished product and the production efficiency are improved, and at the same time, it is helpful to achieve a more complex shoe shape design, and enhance the diversity and market competitiveness of the product. Optionally, the alignment block 111 is arranged on the bottom surface of the upper mold 110, and the elastic positioning block 300 is arranged on the top surface of the mold core 200. Furthermore, the upper mold 110 and the lower mold 120 can cover the mold core 200 more tightly when the mold is closed, ensuring the precise alignment between the mold core 200 and the mold base 100. In addition, the split design of the mold base 100 makes the assembly and disassembly of the entire mold more convenient, facilitates the maintenance and replacement of worn parts, and extends the service life of the mold. Further, referring to Figure 5 and Figure 6 , the elastic positioning block 300 is arranged on the bottom surface of the mold core 200, and the shoe-shaped cavity wall 101 located in the lower mold 120 is provided with a support block 121, and the position of the support block 121 corresponds to the position of the elastic positioning block 300. After the mold is closed and positioned, the support block 121 and the elastic positioning block 300 are pressed and matched, which significantly improves the stability and sealing of the mold. This design enables the position of the support block 121 to correspond to the position of the elastic positioning block 300 during the mold closing process, which can effectively support the mold core 200 and reduce the vibration and displacement of the mold core 200 during the injection molding process, thereby improving the stability and molding accuracy of the mold. In addition, the cooperation between the support block 121 and the elastic positioning block 300 also optimizes the internal matching structure of the mold, so that the pressure can be evenly distributed during the mold closing, reducing the deformation and wear caused by local overpressure, and extending the service life of the mold. Optionally, the support block 121 is elastic, and the material and matching relationship between the alignment block 111 and the positioning block 300 can be referred to, which will not be repeated here. Similar to the manufacturing method of the alignment block 111 , the support block 121 is injection molded in the lower mold 120 , or the support block 121 is embedded and installed in the lower mold 120 .

[0037] In some embodiments of the present invention, Figures 2 to 4As shown, the mold core 200 is provided with a mounting portion 210 that is mounted in cooperation with the mold base 100, the mounting portion 210 is integrally connected with the shoe-shaped portion 220, and the elastic positioning block 300 is located on the side of the shoe-shaped portion 220 away from the mounting portion 210. Specifically, the upper mold 110 is provided with a limiting groove 1101, and the mounting portion 210 is tightly matched with the groove wall of the limiting groove 1101, ensuring the precise positioning of the mold core 200 in the mold, reducing the molding error caused by position deviation, thereby improving the appearance quality and consistency of the finished product. At the same time, the tight fit between the mounting portion 210 and the limiting groove 1101 enhances the fixing effect of the mold core 200, reduces the displacement and vibration during the opening and closing of the mold, and further improves the stability and service life of the mold. In some applications, the mating position between the mounting portion 210 and the limiting groove 1101 is the initial mounting mating position of the mold core 200 and the mold base 100. In this regard, the mating position accuracy between the mold core 200 and the mold base 100 is poor at a position far from the initial mounting mating position. For example, the conventional fully rigid mold core 200 and the mold base 100 often have the problem of hanging in the air at a position far from the initial mounting mating position, causing the plastic raw material to penetrate into the corresponding shoe holes and produce burrs after molding. In this regard, in some embodiments of the present invention, the elastic positioning block 300 is located on the side of the shoe-shaped portion 220 away from the mounting portion 210, ensuring the sealing performance of the key position, especially the edge area of ​​the shoe-shaped cavity wall 101, effectively preventing the plastic raw material from overflowing from these parts during the molding process, and avoiding the burr problem on the edge of the finished product. At the same time, the elastic positioning block 300 is located on the side of the shoe-shaped portion 220 away from the mounting portion 210, which reduces the interference of the elastic positioning block 300 on the mounting portion 210, making the installation and removal of the mold core 200 more convenient and improving the maintenance and replacement efficiency of the mold. In addition, this layout also ensures that the pressure distribution in the shoe-shaped cavity wall 101 is more uniform, reduces deformation and wear caused by local overpressure, and further extends the service life of the mold.

[0038] Optionally, refer to Figure 3 There are multiple elastic positioning blocks 300, and the shapes of the multiple elastic positioning blocks 300 are different, which can adapt to more styles of shoe designs. In application, multiple elastic positioning blocks 300 are arranged at intervals in the shoe-shaped cavity wall 101 to match the external structure of multiple holes on the shoe, which can not only further enhance the sealing effect of the shoe-shaped cavity wall 101, but also further prevent the injection molding material from overflowing from the gap during the molding process, avoiding the burr problem on the edge of the finished product. In addition, the design of multiple elastic positioning blocks 300 makes the pressure more evenly distributed in the shoe-shaped cavity wall 101, reduces the deformation and wear caused by local overpressure, and extends the service life of the mold.

[0039] The hole shoes according to the embodiment of the present invention are made using the hole shoe manufacturing method according to the embodiment of the present invention. The hole shoes produced by the hole shoe manufacturing method have no burrs, high-quality appearance and excellent performance, effectively solving the burr problem caused by mold wear in the traditional manufacturing process, improving the appearance quality and production efficiency of the finished product, extending the service life of the mold, and reducing production costs; at the same time, the method can flexibly adapt to hole designs of different shapes and sizes, significantly improving the market competitiveness and user satisfaction of the product.

[0040] Other structures and operations of the hole shoes according to the embodiment of the present invention are known to ordinary technicians in the field and will not be described in detail here.

[0041] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
