In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application.

[0024] The embodiment of the present application provides a composite injection molded sole, which is described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.
[0025] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.
[0026] See also Figure 1-Figure 7 middle:
[0027] The present application provides a composite injection molded sole, comprising: a sole body 1, a groove 101 is provided on the top of the sole body 1, a polyether layer 102 is provided in the groove 101, a buffer layer 2 is provided on the top of the polyether layer 102, an elastic layer 3 is provided on the top of the buffer layer 2, and a waterproof coating 4 is connected to the top of the elastic layer 3.
[0028] Among them, the polyether layer 102 has better hydrolysis resistance, which means that in a humid environment or long-term contact with moisture, the sole is not prone to hydrolysis and performance degradation, such as cracking or softening, thereby extending the service life of the sole. The polyether layer 102 exhibits better flexural resistance in a low temperature environment, that is, it can still maintain good flexibility and comfort in cold weather, reducing the discomfort caused by the hardening of the sole. At the same time, the setting of the waterproof coating 4 can effectively prevent moisture from penetrating into the sole body 1 from above.
[0029] Among them, by setting the polyether layer 102, the problem of performance degradation caused by hydrolysis of the sole when the sole is in a humid environment or in contact with moisture for a long time can be avoided. By setting the buffer layer 2 and the elastic layer 3, the weight of the sole body 1 can be effectively reduced and the overall elasticity of the sole body 1 can be improved while ensuring wear resistance.
[0030] Furthermore, a cavity is opened at the bottom of the sole body 1, and multiple anti-sliding blocks 103 are connected to the cavity at the forefoot position of the sole body 1. The multiple anti-sliding blocks 103 all protrude from the lower surface of the sole body 1, and the multiple anti-sliding blocks 103 are evenly distributed in the horizontal direction.
[0031] By setting up multiple anti-slip blocks 103, the friction between the sole body 1 and the ground can be increased, and the overall grip of the sole body 1 can be improved. At the same time, multiple anti-slip blocks 103 are evenly distributed to ensure that the sole body 1 has a large contact area with the ground and many contact points, thereby avoiding a small contact area with the ground and few contact points, which may cause insufficient grip and slipping of the sole.
[0032] Among them, multiple rubber blocks 104 are connected between two adjacent anti-slip blocks 103, and the multiple rubber blocks 104 are evenly arranged and distributed in the vertical direction. A wear-resistant block 105 is provided inside the cavity of the sole body 1 at the rear sole position, and the wear-resistant block 105 is made of thermoplastic polyurethane material.
[0033] By setting up multiple rubber blocks 104, on the one hand, two adjacent anti-slip blocks 103 can be supported and reinforced to ensure the stability of the anti-slip blocks 103. At the same time, the rubber blocks 104 protrude from the outer surface of the sole body 1. After the anti-slip blocks 103 are worn, the rubber blocks 104 can increase the anti-slip effect of the sole body 1 to ensure that the service life of the sole body 1 is extended. Then, during walking, the heel of the shoe often contacts the ground first, and the thermoplastic polyurethane material combines the thermoplasticity of plastic and the excellent physical properties of polyurethane. It has excellent mechanical properties, including high strength, high toughness and good tear resistance, and can withstand wear under intense exercise or heavy load conditions.
[0034] Furthermore, the cross-sectional sizes of the buffer layer 2, the elastic layer 3 and the waterproof coating 4 cooperate with the cross-sectional profile of the groove 101, a plurality of elastic rods 202 are connected to the top of the buffer layer 2, and the top ends of the elastic rods 202 are connected to the elastic layer 3, and the plurality of elastic rods 202 are evenly distributed on the surface of the buffer layer 2.
[0035] By setting the buffer layer 2, elastic rod 202 and elastic layer 3, the sole body 1 can be provided with good elasticity and energy feedback, effectively absorbing impact force and converting it into rebound force, which is particularly important for sports shoes, and can reduce the impact of exercise on joints and improve wearing comfort.
[0036] Among them, a plurality of evenly distributed buffer holes 201 are opened inside the buffer layer 2, and the buffer layer 2 is made of ethylene-vinyl acetate copolymer. The setting of multiple buffer holes 201 can effectively reduce the weight of the buffer layer 2, and at the same time, elastic space is left inside the buffer layer 2, thereby improving the buffering effect of the buffer layer 2. Ethylene-vinyl acetate copolymer is light and shock-absorbing, which can effectively reduce the overall weight of the sole body 1 and improve the comfort of the wearer. At the same time, the shock-absorbing property can absorb the impact force during walking or exercise and protect the feet from injury. Then, through the setting of multiple elastic rods 202, a large amount of elastic space is left between the buffer layer 2 and the elastic layer 3.
[0037] Among them, the top of the waterproof coating 4 is provided with an insole 5, and the insole 5 is provided with a plurality of air holes 501. The sole body 1 is made of a lightweight rubber material, and the elastic layer 3 is made of a polyurethane material. The polyurethane material has good cushioning and elasticity, can provide a good cushioning effect, absorb the impact force on the foot and the ground during walking or exercise, reduce sports injuries, and maintain sufficient resilience to provide users with a comfortable foot feel. It also has wear resistance, weather resistance and diversity, can resist long-term friction and wear, and extend the service life of the shoes. It is particularly suitable for work environments or outdoor activities that require frequent walking. The polyurethane material has good adaptability to environmental factors (such as temperature changes and humidity), is not easily aged rapidly due to climate changes, and is suitable for use under a variety of climatic conditions. At the same time, the polyurethane sole can be made into different hardness and density to meet the needs of different types of shoes and application scenarios. From soft-soled comfortable slippers to hard-soled work boots, polyurethane can do it.
