Abstract
A tire body is divided into a first tire fitting part and a second tire fitting part along the radial direction, a fitting groove is formed in the first tire fitting part, a fitting protrusion is formed in the second tire fitting part, and the first tire fitting part and the second tire fitting part are fitted through the fitting groove and the fitting protrusion. The advantage lies in, on the one hand can increase the contact surface of agreeing with the face, and the bonding area is the bigger, and bonding strength is better, and on the other hand through agreeing with the structure, can make two agreeing with the portion no longer rely on its self cohesion alone, agrees with the structure and also can play the positioning action to both.
Description
Technical Field
The utility model relates to a tire especially relates to an injection cavity tire agrees with a structure.
Background
A rubber injection molding machine is a common apparatus for manufacturing rubber products, and extrudes a rubber raw material, injects the raw material into a mold with a large injection force, and molds the raw material in the mold.
Most of injection-molded tires are solid tires, hollow tires are rare, the conventional injection hollow tire divides the tire into two parts which are symmetrical up and down, the upper part and the lower part are respectively subjected to injection molding and then are butted to finish a finished hollow tire product, and in the actual production, the bonding strength of the bonding surface of the upper part and the lower part of the injection hollow tire is weak, the bonding surface is broken and broken after long-term use, and other injection-molded parts are intact, so that the service life of the whole tire is influenced.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems, a structure of the conjunction part of the injection hollow tire is specially made, wherein the conjunction part is firmer and has longer service life.
In order to achieve the above object, the present invention provides the following solutions: a tire body is divided into a first tire fitting part and a second tire fitting part along the radial direction, a fitting groove is formed in the first tire fitting part, a fitting protrusion is formed in the second tire fitting part, and the first tire fitting part and the second tire fitting part are fitted through the fitting groove and the fitting protrusion.
Furthermore, semicircular cavities are respectively arranged on the first tire fitting part and the second tire fitting part, and after the first tire fitting part and the second tire fitting part are fitted, the semicircular cavities form a hollow structure of the tire body.
Furthermore, the edges of two sides of the semicircular cavity are fit surfaces, and the fit grooves and the fit bulges are arranged on the fit surfaces.
Furthermore, the fitting bulges are triangular fitting bulges with triangular sections.
Furthermore, the fitting groove is a triangular fitting groove with a triangular section.
Further, the tire body is made of rubber.
The utility model discloses an useful part lies in:
the tire body is radially cut apart, divide into first tire conjunction portion and second tire conjunction portion, be equipped with the conjunction recess in the first tire conjunction portion, be equipped with the conjunction arch in the second tire conjunction portion, the structure of agreeing with that agrees with the conjunction that recess and conjunction arch constitute, on the one hand can increase the contact surface who agrees with the face, the bonding area is big more, bonding strength is better, on the other hand, through agreeing with the structure, can make two conjunction portions no longer rely on its self cohesion alone, agree with the structure and also can play the positioning action to both.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
A tire body is divided into a first tire fitting part and a second tire fitting part in half along the radial direction, a fitting groove is formed in the first tire fitting part, a fitting protrusion is formed in the second tire fitting part, and the first tire fitting part and the second tire fitting part are fitted through the fitting groove and the fitting protrusion. The first tire conjunction part and the second tire conjunction part are respectively provided with a semicircular cavity, and after the first tire conjunction part and the second tire conjunction part are in conjunction, the semicircular cavities of the first tire conjunction part and the second tire conjunction part form a hollow structure of the tire body. The edges of two sides of the semicircular cavity are fit surfaces, and the fit grooves and the fit bulges are arranged on the fit surfaces. The fitting bulges are triangular fitting bulges with triangular sections. The fitting groove is a triangular fitting groove with a triangular section. The fitting grooves can be in any shapes except for the triangular row state of the section, such as a rectangle, a semicircle and the like, and the tire body is made of rubber. In the actual production process, the first tire fitting part and the second tire fitting part are subjected to one-time injection molding, then the first tire fitting part and the second tire fitting part are subjected to mold assembly, after the mold assembly is carried out, the fitting protrusions and the fitting grooves are fitted, vulcanization molding is carried out, and the fitting structure is completely arranged in the tire body.
It is obvious to a person skilled in the art that the invention is not limited to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention, and that the embodiments are therefore to be considered in all respects as exemplary and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
