They do not indicate or imply that the device or component referred to must have this specific direction or operate with a specific direction structure, and should not be understood as a limitation of the present invention.

[0031] To solve this problem, the utility model proposes a new type of rubber shoe forming mold design. The design includes a replaceable inner mold assembly, so that the inner mold can be easily replaced when producing shoes with different upper heights without replacing the entire forming mold. In this way, the production line can respond to different shoe needs more flexibly, reduce production costs and time consumption, and improve production efficiency.

[0032] In addition, the utility model also takes into account the matching accuracy and stability between the inner mold and the outer mold, ensuring that high-quality molded shoes can be obtained during the production process. Through this innovative design, the patent solves the problem that the inner mold in the traditional rubber shoe molding mold cannot be replaced, bringing higher efficiency and flexibility to the rubber shoe production industry.

[0033] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0034] Please refer to Figure 1 and Figure 2 The utility model provides a multi-style shoe forming mold, including:

[0035] An outer mold assembly 10, wherein a hollow shoe cavity 11 is provided in the outer mold assembly 10, and a cavity wall of the shoe cavity 11 forms a first molding wall for molding the outer side surface of the shoe;

[0036] Through the hollow shoe cavity 11 and the molding wall of the outer mold assembly 10, the shoe can be completely molded in the shape of the outer side during the molding process, ensuring the accuracy and consistency of the shoe appearance. Through the design of the outer mold assembly 10, the outer side of the shoe can be molded more accurately, improving the overall aesthetics and quality of the shoe.

[0037] The multi-style shoe forming mold further includes an inner mold assembly 20, which includes an inner mold body 21. The inner mold body 21 is connected to a driving device and driven by the driving device into the shoe cavity 11 to cooperate with the outer mold assembly 10. When the inner mold body 21 is located in the shoe cavity 11, a molding cavity for molding a shoe body is formed between the inner mold body 21 and the molding wall, and the outer wall of the inner mold body 21 forms a second molding cavity for molding the inner side of the shoe.

[0038] The design of the inner mold assembly 20 can ensure the molding quality and accuracy of the shoe body and the inner side, and at the same time, cooperate with the outer mold assembly 10 to complete the entire shoe molding process. The design of the inner mold assembly 20 makes the inner side of the shoe more accurately molded, and also improves the overall quality and comfort of the shoe body.

[0039] The inner mold assembly 20 includes a first quick-release connector for connecting to the drive device, and a second quick-release connector for connecting to the inner mold body 21. The first quick-release connector is used to rotate and engage with the second quick-release connector to connect the inner mold body 21 to the drive device.

[0040] The design of the quick-release connector simplifies the installation and disassembly process of the inner mold assembly 20, and different types of inner mold bodies 21 can be replaced as needed to achieve the molding of low-top shoes, mid-top shoes and high-top shoes. The utility model improves operating efficiency and convenience, facilitates mold replacement and maintenance, and reduces the operating time and effort of operators.

[0041] Please refer to Figure 3 and Figure 4 Further, the first quick-release connector includes a connecting seat 22, the connecting seat 22 is provided with an arc-shaped card slot 221, the first end of the arc-shaped card slot 221 penetrates the side wall of the connecting seat 22 to form a card interface, and the second end of the arc-shaped card slot 221 is provided with a limiting structure;

[0042] The second quick-release connector includes a clamping column 23, which can be driven from the clamping interface into the arc-shaped clamping slot 221 and slide along the arc-shaped clamping slot 221 into the limiting structure, so that the first quick-release connector is buckled and connected with the second quick-release connector.

[0043] Furthermore, the limiting structure includes a limiting step 222 arranged at the top of the arc-shaped slot 221, and the width of the limiting step 222 increases from the first end to the second end of the arc-shaped slot 221; a limiting head is provided at the end of the clamping column 23.

[0044] By allowing the clamping column 23 to enter from the clamping interface and slide along the arc-shaped clamping groove 221 into the limiting structure under the drive of external force, the limiting head of the clamping column 23 can be limited by the limiting step 222 in the arc-shaped clamping groove 221, so as to realize the buckling connection between the first quick-release connector and the second quick-release connector.

[0045] In this embodiment, a rotating head is rotatably provided at the end of the clamping column 23, and a first thread is provided on the outer periphery of the rotating head; the limiting structure includes a second thread provided at the bottom of the arc-shaped clamping groove 221, and the first thread matches the second thread;

[0046] When the clamping column 23 moves along the first end to the second end of the arc-shaped clamping groove 221 , the rotating head is threadedly connected with the limiting structure.

[0047] Since the thread specifications of the clamping column 23 match those of the strip groove, the clamping column 23 can be further fixed in the arc-shaped clamping groove 221 while being restricted in the arc-shaped clamping groove 221, effectively improving the connection stability between the inner mold body 21 and the driving device.

[0048] Furthermore, a friction layer is provided on the periphery of the clamping column 23, and when the clamping column 23 is limitedly connected with the limiting structure, the friction layer forms an interference fit with the arc-shaped clamping groove 221. It can be understood that the friction layer in the present application is a silicone layer, or other rubber layer with greater friction, and the friction layer forms an interference fit with the arc-shaped clamping groove 221, which can further improve the tightness of the connection between the inner body and the driving device and avoid displacement between the two.

[0049] In this embodiment, the driving device is a cylinder.

[0050] Optionally, the outer mold assembly 10 includes a first outer mold and a second outer mold, a first sliding track is connected between the first outer mold and the second outer mold, and the first outer mold and the second outer mold move toward or away from each other along the sliding track to achieve mold closing or mold opening of the outer mold assembly 10.

[0051] Optionally, the outer mold assembly 10 further includes a first auxiliary mold slidably connected to the top of the first outer mold, and a second auxiliary mold slidably connected to the top of the second outer mold; the first auxiliary mold and the second auxiliary mold can be driven to engage with the first outer mold and the second outer mold respectively;

[0052] When the first auxiliary mold and the second auxiliary mold are connected to the first outer mold and the second outer mold respectively, and the outer mold assembly 10 is molded, the inner walls of the first auxiliary mold and the second auxiliary mold form a second molding wall for molding the outer side of the shoe.

[0053] In the utility model, by setting up an auxiliary mold, after replacing the inner mold body 21 used for molding high-top shoes, the auxiliary mold can be combined with the first outer mold and the second outer mold to adapt to the molding of high-top shoes, further improving the molding process of the outer side of the shoe, ensuring the quality and accuracy of the molding wall, making the molding of the outer side of the shoe more uniform and standardized, and improving the molding efficiency and the quality of the finished product.

[0054] In this application, mid-top, low-top and high-top shoes can be formed simultaneously by a set of molds, and the implementation steps are as follows:

[0055] 1. Mold preparation: Install and adjust the inner mold body 21 to ensure that the inner mold body 21 and the shoe cavity 11 can be correctly aligned and combined to meet the molding requirements of different shoe uppers.

[0056] 2. Pressing: The heated shoe material is placed in a mold and then the appropriate pressure and temperature are applied to form the material into the shape of a mid-top, low-top or high-top shoe.

[0057] 3. Cooling and curing: After the molding is completed, the shoe material is allowed to cool and cure in the mold to ensure that it maintains the desired shape and structure.

[0058] 4. Take out the finished product: After the shoe material has completely cooled, open the mold and take out the formed shoes for subsequent processing and modification, such as trimming, stitching, painting, etc.

[0059] Through the above steps, a set of molds can be used to simultaneously mold mid-top, low-top and high-top shoes, thereby achieving the goal of efficiently producing diversified shoe styles.

[0060] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
