They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0039] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0040] The embodiment of the utility model provides a shoe-making mold for a double-layer ETPU sole, comprising:

[0041] Lower mold 1;

[0042] The first upper mold 2;

[0043] Second upper mold 3;

[0044] The middle mold 4 is matched and connected with the second upper mold 3;

[0045] The lower mold 1 includes a first connecting mechanism 101 connected to the first upper mold 2 and a second connecting mechanism 102 connected to the middle mold 4. The lower mold 1 and the first upper mold 2 form a first sole 103, and the lower mold 1, the middle mold 4 and the second upper mold 3 form a second sole 104. The middle mold 4 is provided with an accommodating space 401, which can accommodate the first sole 103 and the second sole 104.

[0046] The mold consists of four main parts: a lower mold 1, a first upper mold 2, a second upper mold 3 and a middle mold 4. These components work together to manufacture a double-layer ETPU sole.

[0047] The lower mold 1 is the base part of the mold, which is connected to the first upper mold 2 and the middle mold 4 through the first connecting mechanism 101 and the second connecting mechanism 102. The lower mold 1 and the first upper mold 2 form a first sole 103, and the lower mold 1, the middle mold 4 and the second upper mold 3 form a second sole 104.

[0048] The middle mold 4 is designed with a receiving space 401, which can accommodate the first sole 103 and the second sole 104. Such a design allows the first sole 103 to be directly placed in the receiving space 401 of the middle mold 4 after manufacturing, providing a basis for the manufacturing of the second sole 104.

[0049] The first connection mechanism 101 and the second connection mechanism 102 are the connection means between the lower mold 1 and the first upper mold 2 and the middle mold 4. These connection mechanisms can be mechanical structures such as hinges to ensure stable connection and precise fit between mold components.

[0050] First, the lower mold 1 and the first upper mold 2 are connected and clamped via the first connecting mechanism 101 to form a mold space for the first sole 103 .

[0051] Next, the first sole 103 material (such as ETPU) is injected into the space to form the first sole 103 .

[0052] Then, the mold is opened and the first upper mold 2 is removed, and the middle mold 4 is molded with the lower mold 1 and matched with the second upper mold 3 to form a mold space for the second sole 104. At this time, the first sole 103 is already located in the accommodating space 401 of the middle mold 4.

[0053] Finally, the material of the second sole 104 is injected into the mold space formed by the middle mold 4 and the second upper mold 3 to form the second sole 104 compounded with the first sole 103 .

[0054] This design allows the second sole 104 to be manufactured directly on the first sole 103, thereby forming a double-layer sole structure. This method not only improves production efficiency, but also ensures the close combination and consistency between the double-layer soles. This mold is suitable for manufacturing various types of double-layer ETPU soles and has good versatility and adaptability.

[0055] In some embodiments, it also includes:

[0056] A first locking device 5, used for locking the lower die 1 and the first upper die 2;

[0057] The second locking device 6 is used to lock the lower mold 1 , the middle mold 4 and the second upper mold 3 .

[0058] The main function of the first locking device 5 is to ensure that the lower mold 1 is tightly combined with the first upper mold 2 to prevent the mold 4 from being displaced or misaligned during the process of manufacturing the first sole 103. The device can adopt a variety of designs, such as buckles, bolts, wedge locking, etc., to adapt to different mold structures and production requirements.

[0059] The second locking device 6 is similar to the first locking device 5, and is used to ensure the stability of the lower mold 1, the middle mold 4 and the second upper mold 3 when manufacturing the second sole 104. The design of the second locking device 6 may be the same as or different from the first locking device 5, depending on the specific design of the mold and the specific requirements during the production process. This design provides flexibility, allowing manufacturers to select the most appropriate locking mechanism according to the specific conditions of production.

[0060] In some embodiments, it also includes:

[0061] A first positioning mechanism 7, used for positioning the mold closing position of the lower mold 1 and the first upper mold 2;

[0062] The second positioning mechanism 8 is used to position the mold closing position of the lower mold 1 and the middle mold 4;

[0063] The third positioning mechanism 9 is used to position the mold closing position of the middle mold 4 and the second upper mold 3 .

[0064] The first positioning mechanism 7 is used to accurately position the mold closing position of the lower mold 1 and the first upper mold 2 to ensure the manufacturing accuracy of the first sole 103. The positioning mechanism may include guide rails, positioning pins, limit blocks, etc. These components work together to ensure accurate alignment of the mold.

[0065] The second positioning mechanism 8 is used to accurately locate the mold position of the lower mold 1 and the middle mold 4 to ensure the manufacturing accuracy of the second sole 104. The design of the second positioning mechanism 8 may be similar to or different from the first positioning mechanism 7 to adapt to different parts of the mold and production requirements. This design provides flexibility, allowing manufacturers to select the most appropriate positioning mechanism according to the specific conditions of production.

[0066] The third positioning mechanism 9 is used to accurately locate the mold closing position of the middle mold 4 and the second upper mold 3 to ensure the manufacturing accuracy of the second sole 104. The design of the third positioning mechanism 9 may be similar or different from the first positioning mechanism 7 or the second positioning mechanism 8 to adapt to different parts of the mold and production requirements. This design provides flexibility, allowing manufacturers to select the most appropriate positioning mechanism according to the specific conditions of production.

[0067] In this embodiment, the first positioning mechanism 7 is a first limit block arranged on the first upper mold 2, and the lower mold 1 is provided with a first positioning hole that cooperates with the first limit block; the second positioning mechanism 8 is a second limit block arranged on the middle mold 4, and the second limit block can cooperate with the first positioning hole; the third positioning mechanism 9 is a third limit block arranged on the second upper mold 3, and the middle mold 4 is provided with a third positioning hole that cooperates with the third limit block.

[0068] In some embodiments, a plurality of first feed ports 201 are disposed on the first upper mold 2 , and the plurality of first feed ports 201 are connected via a first flow channel 202 disposed on the first upper mold 2 .

[0069] Furthermore, a plurality of first exhaust ports 203 are disposed on the first upper mold 2 , and the first upper mold 2 further comprises a plurality of first exhaust channels 204 connected to the first exhaust ports 203 and extending to the edge of the first upper mold 2 .

[0070] In some embodiments, a plurality of second feed ports 301 are disposed on the second upper mold 3 , and the plurality of second feed ports 301 are connected via a second flow channel 302 disposed on the second upper mold 3 .

[0071] Furthermore, a plurality of second exhaust ports 303 are disposed on the second upper mold 3 , and the second upper mold 3 further includes a plurality of second exhaust channels 304 connected to the second exhaust ports 303 and extending to the edge of the second upper mold 3 .

[0072] In some embodiments, the first connection mechanism 101 or the second connection mechanism 102 is a hinge.

[0073] Furthermore, the first locking device 5 or the second locking device 6 is a buckle.

[0074] Using a buckle as a locking mechanism between the lower mold 1 and the first upper mold 2 can quickly and firmly fix the mold position to prevent displacement during the production process. Similarly, the locking of the lower mold 1 and the second upper mold 3 can also use a buckle to provide a consistent locking effect and ease of operation.

[0075] In some embodiments, the middle mold 4 is connected to the second upper mold 3 via a hinge.

[0076] The connection between the lower mold 1 and the first upper mold 2 adopts a hinge structure, so that the two parts can rotate relative to each other, which is convenient for opening and closing the mold and operating. Similarly, the connection between the lower mold 1 and the second upper mold 3 can also adopt a hinge structure to provide similar rotation and operation convenience. The connection between the middle mold 4 and the second upper mold 3 can also be achieved by a hinge, which helps to accurately align and fix the position when manufacturing a double-layer sole.

[0077] The terms and words used in the above description and claims are not limited to the literal meanings, but are only used by the applicant to enable a clear and consistent understanding of the utility model. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the utility model is provided only for illustration, and not for limiting the utility model as defined by the attached claims and their equivalents.
