Plastic injection molding is a production method in which the rubber is injected directly from the barrel into the mold for vulcanization and bonding of fabric or leather uppers. Injection molding is performed under a certain temperature and pressure to give the upper and sole a certain degree of flexibility and elasticity, and to fuse the two together.

[0003] Some existing injection-molded shoes are simple in internal production and are not breathable and waterproof at the same time. As a result, after wearing the shoes for a long time, the internal odor is strong and more bacteria will breed. Therefore, a breathable and waterproof injection-molded shoe is proposed to solve the above problems. Utility Model Content

[0006] The shoe upper includes a first mesh cloth, the first mesh cloth is connected to the upper part of the sole, one side of the first mesh cloth is connected to a support mesh, and one side of the support mesh is connected to a second mesh cloth;

[0007] A convex piece is connected to one side of the plastic sheet, and a cutout is provided inside the convex piece;

[0008] The sole is provided with a mounting groove, the mounting groove is connected to an air bag, and the air bag is provided with an air hole.

[0009] The insole comprises a soft pad, the soft pad is located on the inner side of the shoe upper, an air passage is opened inside the soft pad, and a third mesh is connected above the soft pad.

[0010] Furthermore, the support net is located between the first mesh and the second mesh, the support net is X-shaped, and the plastic sheet is located outside the second mesh.

[0011] Furthermore, the area of ​​the plastic sheet is smaller than the area of ​​the second mesh, the protrusions are distributed at equal intervals, and the protrusions are located on the side of the plastic sheet away from the second mesh.

[0012] Furthermore, the cutout is in a cross-shaped shape, the cutout is located at the center of the protrusion, and the diameter of the cutout is smaller than the diameter of the protrusion.

[0013] Furthermore, the number of the airbags is consistent with the number of the mounting slots, the upper end of the airbag is arc-shaped, the upper end of the airbag protrudes from the sole, and the air hole is located at the upper end of the airbag.

[0014] Furthermore, the soft pad is located above the sole, the soft pad is located above the airbag, and the air channel is connected to the air hole.

[0015] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0016] The breathable and waterproof injection-molded shoes are provided with air bags. When the foot steps on the shoe, pressure is applied to the insole and the sole. The air in the air bags is discharged through the air holes and then through the air passage, the third mesh and the shoe upper. At the same time, the discharged air expands the incision, allowing the air to be discharged through the incision, thereby improving the breathability. Otherwise, the incision would be sealed.

[0017] The breathable and waterproof injection-molded shoe has a waterproof plastic sheet that does not completely cover the second mesh cloth, so the shoe upper is breathable. When the foot is lifted, the negative pressure air bag inhales air, and the air outside the shoe is sucked into the interior of the air bag through the shoe upper, the third mesh cloth and the air duct through the air holes, so the shoe has the advantage of air circulation.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-7 , a breathable and waterproof injection-molded shoe in this embodiment includes an upper 1, the upper 1 includes a first mesh 101, the first mesh 101 is connected to the top of the sole 3, one side of the first mesh 101 is connected to a bracket net 102, one side of the bracket net 102 is connected to a second mesh 103, the outside of the upper 1 is connected to a plastic sheet 2, one side of the plastic sheet 2 is connected to a convex piece 201, an incision 202 is opened inside the convex piece 201, the bottom of the upper 1 is connected to the sole 3, the sole 3 is opened inside a mounting groove 301, the mounting groove 301 is connected inside an air bag 302, the air bag 302 is opened inside an air hole 303, an insole 4 is provided on the inner side of the upper 1, the insole 4 includes a soft pad 401, the soft pad 401 is located on the inner side of the upper 1, an air channel 402 is opened inside the soft pad 401, and a third mesh 403 is connected above the soft pad 401.

[0028] In the case implementation, the support net 102 is located between the first mesh 101 and the second mesh 103, the support net 102 is X-shaped, the plastic sheet 2 is located outside the second mesh 103, the area of ​​the plastic sheet 2 is smaller than the area of ​​the second mesh 103, and there is space inside the upper 1 for air circulation. The plastic sheet 2 is waterproof, and the plastic sheet 2 does not completely cover the second mesh 103, so the upper 1 is breathable.

[0029] In the case implementation, the number of airbags 302 is consistent with the number of mounting slots 301, the upper end of the airbag 302 is arc-shaped, the upper end of the airbag 302 protrudes from the sole 3, the air hole 303 is located at the upper end of the airbag 302, the cushion 401 is located above the sole 3, the cushion 401 is located above the airbag 302, and the air duct 402 is connected to the air hole 303. After the shoe is worn on the foot, pressure is generated on the insole 4 and the sole 3 when the foot steps on it, so the air in the airbag 302 is discharged through the air hole 303 and discharged through the air duct 402, the third mesh 403 and the upper 1. When the foot is lifted, the negative pressure airbag 302 inhales air, so the air outside the shoe is sucked into the interior of the airbag 302 through the upper 1, the third mesh 403 and the air duct 402 through the air hole 303, so the shoe has the advantage of air circulation.

[0030] In the case implementation, the protrusion 201 is stretchable and is evenly distributed. The protrusion 201 is located on the side of the plastic sheet 2 away from the second mesh 103. The incision 202 is in a M shape and is located at the center of the protrusion 201. The diameter of the incision 202 is smaller than the diameter of the protrusion 201. When the air in the airbag 302 is discharged, the discharged air will expand the incision 202, so that the air can be discharged through the incision 202, making the air permeability better. Otherwise, the incision 202 is sealed.

[0031] During implementation, follow these steps:

[0032] 1) Put the shoes on your feet first;

[0033] 2) Then when the foot steps down, the air in the airbag 302 is discharged;

[0034] 3) When the foot is lifted up, the negative pressure air bag 302 is inhaled.

[0035] To sum up, when the foot steps on the breathable and waterproof injection-molded shoe, pressure is generated on the insole 4 and the sole 3, so the air in the air bag 302 is discharged through the air hole 303 and discharged through the air channel 402, the third mesh 403 and the upper 1. At the same time, the discharged air expands the incision 202, so that the air can be discharged through the incision 202, making the air permeability better. Otherwise, the incision 202 is sealed.

[0036] Moreover, the plastic sheet 2 is waterproof and does not completely cover the second mesh 103, so the upper 1 is breathable. When the foot is lifted, the negative pressure air bag 302 inhales air, and the air outside the shoe is sucked into the interior of the air bag 302 through the upper 1, the third mesh 403 and the air duct 402 through the air hole 303. Therefore, the shoe has the advantage of air circulation, which solves the problem of not having both breathable and waterproof effects at the same time.
