Detailed Embodiment

[0038] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0041] In the description of this application, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "joined" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0042] The sole forming mold, as a special mold equipment for manufacturing soles, precisely shapes the material into the specific shape and structure required for the sole through sophisticated processes such as injection molding and compression molding. Its key role is to ensure that the size of the sole is accurate and the shape is regular, so as to meet the dual requirements of functionality and aesthetics of footwear products, while significantly improving the production efficiency and quality control level.

[0043] Currently, the special mold equipment for soles on the market is often relatively fixed in structure and mainly adapts to the manufacturing requirements of soles with different heights by replacing different molds. The limitation of this method is that once soles with different heights need to be manufactured, the corresponding molds need to be replaced, which undoubtedly increases the production cost and operation complexity.

[0044] Although there are already some mold equipment with height adjustment functions on the market, the adjustment structures of these equipment are often relatively complex and mainly made of metal materials. In the long-term use process of this metal material mold equipment, due to factors such as metal fatigue and wear, it is easy to cause structural failure, and then lead to problems such as part fragmentation and equipment failure. This not only affects the manufacturing quality and efficiency of the soles, but also brings potential safety hazards to the production of enterprises.

[0045] In view of this, in order to solve the problems of low sole manufacturing efficiency and quality caused by structural failure of the sole molding die with height adjustment function due to factors such as technical fatigue and wear, and high equipment maintenance complexity and cost, the present utility model proposes a molding die with adjustable sole height to address the deficiencies of the prior art.

[0046] As Figures 1-3 shown, in some embodiments of the present application, a molding die with adjustable sole height includes: a die, an adjustment unit, and a feed pipe 300. The die has a compression molding space inside, and the compression molding space is used to compress and mold raw materials into soles; the adjustment unit is arranged inside the compression molding space and is slidably connected to the inner side wall of the compression molding space, and the adjustment unit is used to adjust the height of the sole; one end of the feed pipe 300 passes through the outer side wall of the die and is arranged inside the compression molding space, and the other end of the feed pipe 300 is communicated with a storage bin, and the feed pipe 300 is used to introduce the raw materials inside the storage bin into the compression molding space.

[0047] Specifically, through the compression molding space provided inside the die, the raw materials are compressed and molded into soles in this space. Through the design of the compression molding space, the die can ensure that the raw materials are evenly distributed under high pressure, so that the molded soles have good density and uniformity. Secondly, the adjustment unit is one of the key components of the die. It is installed inside the compression molding space and is slidably connected to the inner side wall of the compression molding space. This sliding connection design allows the adjustment unit to move freely inside the compression molding space, so that the height of the sole can be adjusted as needed. The flexibility of the adjustment unit enables the die to adapt to the production requirements of different types of soles. Whether it is a thin sole or a thick sole, it can be achieved through simple adjustment. This not only increases the product diversity, but also reduces the frequency of die replacement and lowers the production cost. At the same time, the feed pipe 300 plays the role of automatic feeding. One end of it passes through the outer side wall of the die and directly leads into the compression molding space, and the other end is connected to the storage bin. Such a design ensures that the raw materials can be continuously and stably transported to the compression molding space, avoiding the molding quality problems caused by uneven raw material supply. The realization of automatic feeding not only improves the production efficiency, but also reduces the manual operation links and the possibility of errors. Finally, this design also improves the durability and stability of the die. The sliding connection design between the adjustment unit and the inner side wall of the compression molding space enables the adjustment unit to slide smoothly when adjusting the height, reducing mechanical wear and failure rate, and extending the service life of the die. The stable structural design ensures the accuracy and consistency of the soles during the molding process, further improving the product quality.

[0048] In some embodiments of the present application, the mold includes: an upper mold module 110, a connecting hinge 130, and a lower mold module 120. On one side of the upper mold module 110, a first shaping groove 111 is provided; one end of the connecting hinge 130 is fixedly connected to one end of the upper mold module 110; one end of the lower mold module 120 is fixedly connected to the other end of the connecting hinge 130. On one side of the lower mold module 120, a second shaping groove 121 is provided, and the second shaping groove 121 is arranged corresponding to the first shaping groove 111; wherein, when the upper mold module 110 rotates along the axial direction of the connecting hinge 130 to be connected to the lower mold module 120, a compression molding space is formed between the first shaping groove 111 and the second shaping groove 121.

[0049] Specifically, through the combined design of the upper mold module 110, the connecting hinge 130, and the lower mold module 120, especially when the upper mold module 110 rotates along the axial direction of the connecting hinge 130 to be connected to the lower mold module 120, the compression molding space formed between the first shaping groove 111 and the second shaping groove 121 can achieve efficient shaping of the material. This design makes the sole compression molding process more direct and effective, effectively improving the production efficiency. Secondly, due to the connection and rotation design between the upper mold module 110, the connecting hinge 130, and the lower mold module 120, the entire shaping process becomes simpler and more convenient. The user only needs to perform a simple operation to connect the upper mold module 110 and the lower mold module 120 to form the required compression molding space, thereby realizing the shaping of the material. At the same time, through the use of the connecting hinge 130, the connection between the upper mold module 110 and the lower mold module 120 is more stable, ensuring the stability and reliability during the shaping process. This stability not only ensures the consistency of the shaping effect but also extends the service life of the device. Finally, the shaping grooves on the upper mold module 110 and the lower mold module 120 can be customized and replaced according to needs, enabling the device to be applicable to the shaping of materials with different shapes and sizes. This flexibility makes the device have broad application prospects in multiple fields.

[0050] In some embodiments of the present application, the upper mold module 110 includes: a first module 112, a second module 113, and a first mounting nail. The middle and lower parts of one ends of the first module 112 and the second module 113 are respectively connected to one end of the connecting hinge 130. A first groove is formed on one side of the first module 112, and a second groove is formed on one side of the second module 113, and the first groove and the second groove are arranged opposite to each other, so that a first shaping groove 111 is formed between the first groove and the second groove; wherein, on the ends of the first module 112 and the second module 113 connected to the connecting hinge 130, first mounting holes are respectively formed; the first mounting nail is arranged on the side of the connecting hinge 130 away from the first mounting hole, and after passing through one end of the connecting hinge 130, the first mounting nail is threadedly connected to the first mounting hole.

[0051] Specifically, a first groove is provided on one side of the first module 112, and a second groove is provided on one side of the second module 113. These two grooves are arranged opposite to each other, aiming to form a complete first shaping groove 111 when the first module 112 and the second module 113 are closed. This shaping groove is a key part of the molded sole, which determines the shape and size of the sole. The precise alignment and tight combination of the grooves ensure high precision and consistency during the molding process, thereby improving the quality of the finished product. To ensure the stable connection and positioning of the first module 112 and the second module 113, first mounting holes are respectively provided at one end of these two modules connected to the connecting hinge 130. The first mounting nail is a key component for connecting and fixing these two modules. The first mounting nail is arranged on the side of the connecting hinge 130 away from the first mounting hole. By passing through one end of the connecting hinge 130 and being threadedly connected to the first mounting hole, the firm connection of the modules is ensured. This design not only guarantees the stability of the modules but also makes the installation and disassembly of the modules more convenient.

[0052] It can be understood that through the ingenious combination of the hinge and the mounting nail, the flexible adjustment and stable connection of the modules are achieved. The grooves of the first module 112 and the second module 113 are precisely aligned to form a complete shaping groove, thereby ensuring high precision during the molding process. The connecting hinge 130 provides the necessary flexibility, enabling the modules to be conveniently opened and closed and adjusted, while the fixing effect of the first mounting nail ensures the stability of the connection. This design effectively improves the operability and reliability of the mold, providing a solid guarantee for the high-quality molding of the sole.

[0053] In some embodiments of the present application, the lower mold set 120 includes: a third module 122, a fourth module 123, and a second mounting nail. The upper middle parts of one ends of the third module 122 and the fourth module 123 are respectively connected to the other end of the connecting hinge 130. A third groove is provided on one side of the third module 122, and a fourth groove is provided on one side of the fourth module 123, and the third groove and the fourth groove are arranged corresponding to each other, so as to form a second shaping groove 121 between the third groove and the fourth groove; wherein, a slide rail is provided in the upper middle part of the inner side wall of the second shaping groove 121, and second fixing holes are respectively provided on the sides of the third module 122 and the fourth module 123 connected to the connecting hinge 130; the second mounting nail is arranged on the side of the connecting hinge 130 away from the second mounting hole, and the second mounting nail passes through one end of the connecting hinge 130 and is threadedly connected to the second mounting hole.

[0054] In some embodiments of the present application, the depth of the first shaping groove 111 is less than that of the second shaping groove 121.

[0055] In some embodiments of the present application, the adjusting unit includes: an adjusting airbag 210 and a plastic pressing plate 220. The adjusting airbag 210 is disposed inside the second shaping groove 121 and is fixedly connected to the inner bottom surface of the second shaping groove; the plastic pressing plate 220 is disposed inside the second shaping groove 121 and is slidably connected to the slide rail; wherein, one side of the plastic pressing plate 220 is connected to the side of the adjusting airbag 210 away from the inner bottom surface of the second shaping groove, and the other side of the plastic pressing plate 220 is provided with sole patterns.

[0056] Specifically, the adjusting airbag 210 is arranged inside the second shaping groove 121 and is firmly connected to the inner bottom surface of the groove. It adjusts the thickness or height of the sole by inflating or releasing gas. When the adjusting airbag 210 is inflated, it gradually expands and pushes the plastic pressing plate 220 downward to compact and form the sole material. When it is necessary to adjust the sole height or reduce the thickness, the adjusting airbag 210 releases gas, and the plastic pressing plate 220 moves upward, making the sole material relatively loose and facilitating the adjustment of the forming effect. The plastic pressing plate 220, as another part of the adjusting unit, is placed inside the second shaping groove 121 and is slidably connected to the slide rail to ensure its smooth movement during the adjustment process. One side is connected to the adjusting airbag 210, and the other side is provided with sole patterns for imparting the required texture and pattern to the formed sole. This design not only enables precise control of the sole thickness during adjustment but also ensures that the texture and appearance of the sole surface meet the design requirements.

[0057] It can be understood that by adjusting the gas pressure and release of the adjusting airbag 210 and the up and down movement of the plastic pressing plate 220, the thickness and height of the sole can be adjusted to meet the production requirements of different types and styles of soles. This technical principle ensures the quality and consistency of the sole during the forming process and improves production efficiency and product reliability.

[0058] In some embodiments of the present application, the adjusting airbag 210 includes: a body and a gas conduit 212. The body is disposed inside the second shaping groove 121, one side of the body is fixedly connected to the inner bottom surface of the second shaping groove, and the other side of the body is connected to the other side of the plastic pressing plate 220 provided with sole patterns; one end of the gas conduit 212 is communicated with the body, and the other end of the gas conduit 212 passes through the inner side wall of the second shaping groove and is respectively connected to the third module 122 and the fourth module 123. The gas conduit 212 is used for guiding gas.

[0059] An adjustable sole height forming mold in each of the above embodiments enables the height of the sole to be flexibly adjusted according to different requirements by introducing an adjustment unit. Whether producing high heels, sports shoes or casual shoes, the height change can be achieved through simple adjustment. This flexibility not only improves the adaptability of the production line but also reduces the frequency of mold replacement, thereby reducing production costs. Secondly, the mold realizes the automatic introduction of raw materials through the feed pipe 300. The feed pipe 300 is directly connected to the storage bin and passes through the outer wall of the mold at one end, ensuring that the raw materials can enter the compression molding space stably and continuously. This design not only simplifies the operation process but also reduces the manual participation link and the error caused by manual operation. At the same time, the realization of automatic feeding improves production efficiency and makes large-scale production possible. Finally, through the design of the sliding connection between the adjustment unit and the inner wall of the compression molding space, the durability and stability of the mold are improved. When adjusting the height, the adjustment unit can slide smoothly, ensuring the accuracy and consistency of the sole during the molding process. This design not only improves the product quality but also extends the service life of the mold.
