[0026] The utility model provides the following description with reference to the accompanying drawings to help fully understand the various embodiments of the utility model as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the utility model.

[0027] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. 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.

[0028] 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.

[0029] The embodiment of the utility model provides an efficient sole forming mold capable of rapid cooling, comprising:

[0030] A die 1, wherein a sole punch 101 is provided inside the die 1, and a first circulating water pipeline 102 is provided inside the die 1;

[0031] The bottom mold 2 is placed under the pressing mold 1 and cooperates with the pressing mold 1. The bottom mold 2 is provided with a shoe sole concave mold 201. The bottom mold 2 is provided with a second circulating water pipeline 202;

[0032] The upper surface of the die 1 is provided with a first water outlet 103 , a first water inlet 104 and a second water inlet 105 , and the lower surface of the bottom die 2 is provided with a second water outlet 203 , a third water outlet 204 and a third water inlet 205 .

[0033] The die 1 contains a sole-shaped convex mold inside, the bottom mold 2 is a mold placed below the die 1 and used in conjunction with the die 1, and contains a sole-shaped concave mold inside, the first circulating water pipeline 102 is set inside the die 1, and is used to cool the die 1 and the sole convex mold 101, the second circulating water pipeline 202 is set inside the bottom mold 2, and is used to cool the bottom mold 2 and the sole concave mold 201, and circulating water pipelines are respectively set in the die 1 and the bottom mold 2, and the circulating water pipelines are set with multiple water inlets or outlets, which shortens the distance of the cooling pipeline, increases the speed of the coolant circulation, makes the coolant flow more evenly, and improves the cooling effect.

[0034] In some embodiments, the first circulating water pipeline 102 is disposed between the upper surface of the pressing mold 1 and the sole convex mold 101 , and the second circulating water pipeline 202 is disposed between the lower surface of the bottom mold 2 and the sole concave mold 201 .

[0035] The setting of the water pipeline helps to achieve uniform distribution of cooling water on the working surface of the mold, thereby reducing molding defects caused by uneven cooling. Due to the short distance between the water pipeline and the working surface of the mold, the cooling water can absorb and conduct heat faster, achieving rapid cooling.

[0036] Furthermore, the first water outlet 103, the first water inlet 104 and the second water inlet 105 are arranged at the toe position of the sole male mold 101, the first water outlet 103 is arranged in the middle, the first water inlet 104 and the second water inlet 105 are respectively arranged on both sides of the first water outlet 103, the second water outlet 203, the third water outlet 204 and the third water inlet 205 are arranged at the toe position of the sole female mold 201, the third water inlet 205 is arranged in the middle, the second water outlet 203 and the third water outlet 204 are respectively arranged on both sides of the third water inlet 205.

[0037] The layout of the water outlet in the middle and the water inlet on both sides, and / or, the layout of the water inlet in the middle and the water outlet on both sides helps to form an effective water circulation, thereby improving cooling efficiency. Uniform cooling can reduce shrinkage, warping or other molding defects caused by uneven cooling. This design can adjust the layout of the water outlet and water inlet according to different sole designs and material properties to meet different production needs. The centralized layout of the water outlet and water inlet makes it easy to monitor the flow of cooling water and also facilitates maintenance and cleaning.

[0038] Furthermore, the first circulating water pipeline 102 includes a first U-shaped pipeline 106 arranged above the left foot part of the sole punch 101 and a second U-shaped tube 107 arranged above the right foot part of the sole punch 101, one end of the first U-shaped pipeline 106 is connected to the first water inlet 104, and the other end is connected to the first water outlet 103, and one end of the second U-shaped tube 107 is connected to the first water outlet 103, and the other end is connected to the second water inlet 105.

[0039] The U-shaped pipe design helps improve the heat exchange efficiency of the coolant because the coolant can circulate above the sole punch 101. If the sole design is different between the left and right foot parts, the independently controlled U-shaped pipe can adapt to these design differences to ensure that both sides can be properly cooled. By setting up separate U-shaped pipes for the left and right foot parts, the cooling water flow on both sides can be independently controlled to adapt to different cooling needs.

[0040] Furthermore, the second circulating water pipeline 202 includes a main pipeline 206 arranged in the middle of the sole mold 201 and extending along the length direction of the sole. The main pipeline 206 is divided into a second pipeline 207 and a third pipeline 208 on both sides at the tail of the sole mold 201. One end of the main pipeline 206 is connected to the third water inlet 205, the second pipeline 207 extends around the outer contour of the sole mold 201 and is finally connected to the second water outlet 203, and the third pipeline 208 extends around the outer contour of the sole mold 201 and is finally connected to the third water outlet 204.

[0041] The circulating water pipeline extends along the length of the sole to cool the sole more effectively. The main pipeline 206 is divided into the second and third pipelines 208 at the tail position of the shoe, which can cool the tail area of ​​the sole more effectively, which helps to improve the cooling uniformity of the entire sole. The second and third pipelines 208 extend around the outer contour of the sole concave mold 201, providing a longer cooling path and increasing the time and efficiency of heat exchange.

[0042] In some embodiments, the diameter of the first circulating water pipeline 102 or the second circulating water pipeline 202 is 18 mm.

[0043] The 18mm diameter provides a larger water flow channel, which can increase the flow rate of cooling water and thus improve cooling efficiency.

[0044] In some embodiments, the cross section of the first circulating water pipeline 102 or the second circulating water pipeline 202 is circular.

[0045] In some embodiments, the distance between the first circulating water pipeline 102 and the sole male mold 101 is 2 to 3 times the diameter of the first circulating water pipeline 102 , and the distance between the second circulating water pipeline 202 and the sole female mold 201 is 2 to 3 times the diameter of the second circulating water pipeline 202 .

[0046] Keeping a certain distance ensures that the cooling water can effectively absorb the heat of the mold, while avoiding the reduction of cooling efficiency due to excessive distance. Leaving a certain space between the mold and the water pipe can accommodate the slight dimensional changes that occur in the mold during use due to thermal expansion.

[0047] In some embodiments, the first circulating water pipeline 102 and the second circulating water pipeline 202 are respectively connected to different water circulation devices.

[0048] Each circulating water pipeline is connected to a different water circulation device to allow independent temperature control of the compression mold 1 and the bottom mold 2, thereby preventing uneven heat dissipation and adapting to different cooling requirements.

[0049] 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.
