[0028] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0033] Please refer to Figure 1-Figure 3 The utility model provides a split side panel, comprising: a side panel body 1; a magnetic device, which is arranged in the side panel body; a matching ring 4, which is magnetically adsorbed and connected to the side panel body 1 through the magnetic device. The inner side surface of the matching ring 4 has an oblique cone surface, and the side panel body 1 is matched with the matching ring 4 through the oblique cone surface, and the matching clearance of the oblique cone surface is less than 0.06mm. Through the matching of the oblique cone surface, the oblique cone surface plays a certain guiding and positioning role, which is beneficial to the matching of the side panel body 1 and the matching ring 4; at the same time, during assembly, the matching clearance of the oblique cone surface is ensured to be less than 0.06mm. This clearance can achieve the effect of air leakage but not rubber leakage, and prevent the rubber from overflowing from the matching clearance between the side panel body 1 and the matching ring 4 during tire vulcanization, which affects the surface molding quality of the tire.

[0034] The side panel body is provided with a plurality of grooves 2, and the magnetic device 3 is arranged in the groove 2 of the side panel body 1. The preferred magnetic device 3 is a permanent magnetic magnet such as a magnet or a non-permanent magnetic magnet such as an electromagnet. The magnetic attraction force provided by the magnetic device 3 magnetically adsorbs the mating ring 4 and the side panel body 1 together.

[0035] Specifically, a plurality of grooves 2 are processed circumferentially on the side panel body 1, and the magnetic device 3 is placed in the groove 2, and the magnetic device is recessed 0-0.03mm from the surface of the side panel body 1. At the same time, two side panel body positioning pin holes are processed on the side panel body 1, and internal threaded cylindrical pins are built into the pin holes. Two matching ring positioning pin holes are processed on the back of the matching ring 4, corresponding to the side panel body positioning pin holes. In this way, the front disassembly of the matching ring 4 can be achieved. It can be understood that the conventional split side panel is connected from the back of the side panel using screws or the like. When disassembly is required, the side panel needs to be removed from the tire mold base before the split side panel can be disassembled. Multiple disassembly of the side panel will inevitably affect the assembly accuracy of the tire mold, and the disassembly operation is more cumbersome.

[0036] The matching ring 4 is provided with an exhaust hole 5 , and the exhaust hole 5 penetrates the side plate cavity surface 81 ; further, the matching ring 4 is provided with an exhaust groove 6 on a side away from the side plate cavity surface 81 , and the exhaust groove 6 is connected with the exhaust hole 5 .

[0037] Specifically, the mating ring 4 is provided with a plurality of exhaust holes 5 and exhaust grooves 6, which are arranged according to needs. The exhaust holes 5 penetrate the side plate cavity surface 81, and the exhaust grooves 6 are arranged on the side of the mating ring 4 away from the side plate cavity surface 81. The exhaust grooves 6 can be shallow grooves on the outer surface of the mating ring 4, and the exhaust grooves 6 are connected to the outer side surface of the mating ring 4. Through the connection between the exhaust holes 5 and the exhaust grooves 6, the gas impurities in the cavity during tire vulcanization can be discharged in time to prevent residual gas from affecting the tire vulcanization quality; at the same time, compared with the integral side plate, the exhaust holes 5 of the split side plate can be arranged in the mating ring 4, and the length of the exhaust holes 5 is shorter, which is not only conducive to processing, but also conducive to later maintenance and cleaning.

[0038] It should be noted that the side plate cavity surface 81 refers to the surface that contacts the tire during tire vulcanization. In a tire mold, the cavity surface is usually composed of pattern blocks 9 and side plates 8 to form the tire surface.

[0039] like Figure 1 and Figure 2 As shown, the matching ring 4 is provided with a hoisting hole 7 for hoisting or taking the matching ring 4 .

[0040] Specifically, the hoisting holes 7 are processed on the outer side of the matching ring 4, and the number of the hoisting holes 7 is 4 or 6. When disassembly is required, the hoisting ring or other clamping device can be connected to the hoisting hole 7, which is convenient for hoisting by a hoisting device or a manipulator, etc. In this way, it is convenient for front hoisting and helps to overcome the magnetic attraction of the magnetic device 3.

[0041] In another embodiment, there are multiple matching rings 4, and the multiple matching rings 4 are arranged in sequence along the radial direction of the side plate body 1. The inner side surface of the outermost matching ring 4 has an oblique cone surface, and the inner and outer side surfaces of the remaining matching rings 4 all have oblique cone surfaces. The multiple matching rings are matched together through the oblique cone surfaces and matched with the side plate body 1 through a magnetic device. In addition, the rest of the parts are basically the same as the previous embodiment and will not be repeated.

[0042] In another embodiment, the utility model further provides a tire mold, which includes the above-mentioned split side panel.

[0043] The above description is only a specific embodiment of the present disclosure, so that those skilled in the art can understand or implement the present disclosure. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present disclosure. Therefore, the present disclosure will not be limited to the embodiments described herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
