Description

Technical Field

[0001] The invention relates to the technical field of soles, and in particular to an anti-skid sole and a forming mold thereof. Background Art

[0002] In daily life, in order to prevent the soles from slipping, anti-skid patterns are usually added to the soles to increase the friction between the soles and the ground. In the prior art, the anti-skid patterns are mostly wavy convex patterns, which can have a certain anti-skid effect, but the adsorption force of the soles is insufficient. If you walk on the ground with accumulated water, the water seeps into the anti-skid patterns of the soles and cannot be discharged, and the slip phenomenon will still occur, thereby greatly reducing the anti-skid effect of the soles.

[0003] In view of this, the applicant conducted in-depth research on the above issues, which led to the present case. Summary of the invention

[0004] The main purpose of the present invention is to provide an anti-skid sole and a forming mold thereof, which can enhance the adsorption force of the sole and improve the anti-skid effect.

[0005] In order to achieve the above object, the solution of the present invention is:

[0006] A non-slip sole comprises a sole body, wherein the sole body is provided with a plurality of anti-slip bumps protruding downward, wherein the anti-slip bump is a truncated cone, and a countersunk hole is provided in the center of the anti-slip bump, and a plurality of V-shaped grooves extending toward the bottom surface are provided on the upper surface of the anti-slip bump, wherein the V-shaped grooves are evenly distributed around the center of the anti-slip bump and divide the anti-slip bump into a plurality of arc-shaped bump monomers, wherein the anti-slip bumps are arranged in a matrix to form an anti-slip combination, and the bottoms of adjacent anti-slip bumps are in contact with each other to form an exhaust port.

[0007] Furthermore, the anti-skid groups are arranged in a matrix, and exhaust grooves are formed between adjacent anti-skid groups, and the exhaust ports are connected to the exhaust grooves.

[0008] Furthermore, the sole body and the anti-slip protrusions are integrally formed.

[0009] The present invention also provides a molding mold for molding the above-mentioned anti-slip sole, which includes an upper mold and a lower mold, the upper mold is provided with an upper mold groove forming the upper surface of the anti-slip sole, the lower mold is provided with a lower mold groove forming the lower surface of the anti-slip sole, the lower mold groove is provided with a plurality of annular grooves, the annular groove is composed of a plurality of equally spaced arc grooves, and the groove walls at the front and rear ends of the arc groove are inclined.

[0010] Furthermore, the annular grooves are arranged in a matrix pattern in groups of four to form a groove combination, and the groove combination is arranged in a matrix pattern in the lower mold groove.

[0011] Furthermore, the upper die groove and the lower die groove are processed by precision carving.

[0012] Furthermore, the upper template and the lower template are made of aviation aluminum material.

[0013] After adopting the above structure, the present invention relates to an anti-skid sole and a molding mold thereof. Compared with the prior art, the beneficial effect lies in that the anti-skid protrusion is a frustum, and a countersunk hole is opened in the center of the anti-skid protrusion, and the V-shaped groove divides the anti-skid protrusion into a plurality of arc-shaped protrusion monomers. When the anti-skid protrusion is deformed by the extrusion force, the front and rear ends of adjacent arc-shaped protrusion monomers abut against each other to form a first closed hole in the center of the anti-skid protrusion, and the outer side walls of adjacent anti-skid protrusions also abut against each other to form a second sealed hole. Since the air in the anti-skid protrusion is discharged from the V-shaped groove, the first sealed hole and the second sealed hole are in a vacuum state, tightly adsorbing to the ground, thereby increasing the adsorption force of the sole and improving the anti-skid effect.

[0014] The present invention is provided with anti-skid bumps, which are arranged in a matrix and form exhaust ports. When the sole contacts the ground, the air between the anti-skid bumps and the ground is accelerated to be discharged from the exhaust ports, so that the lower surface of the anti-skid bumps fits tightly with the ground, further improving the anti-skid effect.

[0015] In addition, the surface of the molding mold of the present invention is finely carved from aviation aluminum material and has extremely high surface accuracy, so that the molded anti-slip sole has clearer texture and a smoother surface, which is beneficial for the adsorption of the sole with the ground and enhances the anti-slip ability of the sole.

[0029] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0030] like Figure 1-5 As shown, a shoe comprises a sole body 1, wherein the sole body 1 is provided with a plurality of anti-skid protrusions 2 protruding downward, wherein the anti-skid protrusion 2 is a frustum of a cone, and a countersunk hole is provided at the center of the anti-skid protrusion 2, the outer side surface of the anti-skid protrusion 2 is inclined outward from top to bottom, and the inner side surface of the anti-skid protrusion 2 is inclined inward from top to bottom, and a plurality of V-shaped grooves 21 extending toward the bottom surface are provided on the upper surface of the anti-skid protrusion 2, and the V-shaped grooves 21 are evenly distributed around the center of the anti-skid protrusion 2, and divide the anti-skid protrusion 2 into a plurality of arc-shaped protrusion monomers 22.

[0031] As one embodiment of the present invention, the anti-skid protrusions 2 are arranged in a matrix in groups of four to form an anti-skid assembly 3 , and the bottoms of adjacent anti-skid protrusions 2 are in contact with each other to form a V-shaped exhaust port 31 .

[0032] After adopting the above structure, compared with the prior art, the anti-skid protrusion 2 of the present invention is an annular frustum, and the V-shaped groove 21 divides the anti-skid protrusion 2 into multiple arc-shaped protrusion monomers 22. When the anti-skid protrusion 2 is deformed by the extrusion force, the front and rear ends of adjacent arc-shaped protrusion monomers 22 are pressed against each other to form a first closed hole 23 in the center of the anti-skid protrusion, and the outer side walls of adjacent anti-skid protrusions 2 are also pressed against each other to form a second sealed hole 24. Since the air in the anti-skid protrusion is discharged from the V-shaped groove 21, the first sealed hole 23 and the second sealed hole 24 are in a vacuum state, tightly adsorbing the ground, thereby increasing the adsorption force of the sole and improving the anti-skid effect.

[0033] Preferably, the anti-skid combination 3 is arranged in a matrix, and exhaust grooves 32 are formed between adjacent anti-skid combinations 3. The exhaust port 31 is connected to the exhaust groove 32. After adopting the above structure, when the sole contacts the ground, the air between the anti-skid protrusion 2 and the ground is first discharged from the exhaust port 31 into the exhaust groove 32, and then discharged from the sole from the exhaust groove 32, so that the lower surface of the anti-skid protrusion 2 is closely fitted with the ground, further improving the anti-skid effect.

[0034] Preferably, the sole body 1 and the anti-skid protrusions 2 are integrally formed, so that the anti-skid sole of the present invention is more convenient to process, has higher structural strength, and improves service life.

[0035] like Figure 6-8 As shown, the present invention also provides a molding mold for molding the above-mentioned anti-slip sole, which includes an upper mold plate 4 and a lower mold plate 5, wherein the upper mold plate 4 is provided with an upper mold groove 41 for forming the upper surface of the anti-slip sole, and the lower mold plate 5 is provided with a lower mold groove 51 for forming the lower surface of the anti-slip sole, and the upper mold groove 41 and the lower mold groove 51 cooperate with each other to form a molding cavity, and the lower mold groove 51 is provided with a plurality of annular grooves 52, and the annular groove 52 is surrounded by a plurality of equally spaced arc grooves 521, and the groove walls at the front and rear ends of the arc groove 521 are inclined from top to bottom in the groove direction.

[0036] Preferably, the upper mold groove 41 and the lower mold groove 51 are finely carved so that the upper mold groove 41 and the lower mold groove 51 of the mold have higher surface accuracy, so that the molded anti-slip sole has clearer texture and a smoother surface, which is beneficial to the adsorption of the sole with the ground and enhances the anti-slip ability of the sole.

[0037] Preferably, the upper template 4 and the lower template 5 are made of aviation aluminum material, so that the mold is not easy to warp, crack and deform during processing, which greatly improves the processing accuracy and service life of the mold.

[0038] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
