Description

Technical Field

[0001] This utility model belongs to the field of tire mold technology, and specifically relates to a tire mold. Background Technology

[0002] In the field of tire mold insulation, flexible insulation sleeves are gradually becoming more common due to their excellent energy-saving effect. Currently, the installation of flexible insulation sleeves mostly involves directly connecting them to the mold and the insulation sleeve with screws or securing them with cable ties. If the insulation sleeve is directly fixed to the mold with screws by drilling holes, the insulation material will be exposed, shortening the life of the insulation sleeve. Each time the insulation sleeve is removed, the bolts need to be removed, making disassembly and assembly cumbersome. If cable ties are used to secure them, the insulation sleeve is prone to falling off, and because the insulation sleeve is under uneven stress, the tightening effect is poor. Disassembly and assembly are also complicated and require additional tools, making disassembly and assembly inconvenient. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a tire mold, including a guide ring and a heat insulation sleeve. The guide ring is a ring-shaped part, and the heat insulation sleeve is arranged around the outside of the guide ring. Elastic clips are provided at both the upper and lower ends of the guide ring.

[0004] The elastic clip is installed on the outside of the guide ring by screws.

[0005] Furthermore, the elastic clip includes an inner wall, a bottom wall, and an outer wall;

[0006] The inner wall, bottom wall, and outer wall are all planar. The inner wall is perpendicular to the bottom wall, and the outer wall approaches the inner wall in a direction away from the bottom wall. The inner wall, bottom wall, and outer wall form a U-shaped cavity for clamping the insulation sleeve.

[0007] Furthermore, a groove is provided on the outer circle of the guide ring, the inner wall is provided in the groove, a threaded hole is provided in the groove, and a first through hole is provided on the inner wall. The first through hole and the threaded hole are correspondingly provided, and the screw passes through the first through hole and is installed in the threaded hole.

[0008] A second through hole corresponding to the first through hole is provided on the outer wall.

[0009] Furthermore, the first through hole is a circular hole or an oblong hole;

[0010] The shape of the second through hole is the same as the shape of the first through hole.

[0011] Furthermore, the groove depth is equal to the thickness of the inner wall.

[0012] Furthermore, a flange is provided on the outer side of the outer wall, the flange is close to the outer wall, and there is a smooth transition between the flange and the outer wall.

[0013] Furthermore, 4 to 8 elastic clips are provided at the upper and lower ends of the guide ring.

[0014] Furthermore, the first through hole on the inner wall of the elastic clamp at the lower end of the guide ring is circular, and the first through hole on the inner wall of the elastic clamp at the upper end of the guide ring is oblong.

[0015] The technical solution provided by this utility model has the following advantages compared with the prior art:

[0016] This utility model provides a tire mold in which an insulating sleeve is arranged around the outside of a guide ring. Elastic clips are provided at both the upper and lower ends of the guide ring. The elastic clips are detachably installed on the outside of the guide ring. The inner wall, bottom wall, and outer wall of the elastic clip form a U-shaped cavity, which facilitates the clamping of the insulating sleeve. Compared to directly fixing it to the guide ring with screws, the insulating sleeve does not need to be partially damaged by screw penetration, thus improving its service life. Furthermore, the insulating sleeve is installed by being clamped to the outside of the guide ring using the elastic clips, and can be removed simply by pulling it out from within the elastic clips, without needing to remove screws or cable ties, making installation and replacement convenient.

[0034] Example 1

[0035] Please refer to Figures 1-6This embodiment provides a tire mold, including a guide ring 1 and an insulation sleeve 2. The guide ring 1 is a ring-shaped part, and the insulation sleeve 2 surrounds the outside of the guide ring 1. Elastic clips 3 are provided at both the upper and lower ends of the guide ring 1. The elastic clips 3 are detachably installed on the outside of the guide ring 1 by screws 4. The elastic clips are used to clamp the insulation sleeve. Compared with directly fixing it to the guide ring with screws, the insulation sleeve does not need to be damaged by the screws, which improves the service life of the insulation sleeve. Moreover, when the insulation sleeve is installed, it is clamped on the outside of the guide ring by the elastic clips. When it is removed, it only needs to be pulled out from the elastic clips without removing the screws or cable ties, which is convenient for installation and replacement.

[0036] The elastic clip 3 includes an inner wall 31, a bottom wall 32, and an outer wall 33. The inner wall 31, the bottom wall 32, and the outer wall 33 are all planar. The inner wall 31 is perpendicular to the bottom wall 32, and the outer wall 33 approaches the inner wall 31 in a direction away from the bottom wall 32. The inner wall 31, the bottom wall 32, and the outer wall 33 form a U-shaped cavity, and the outer wall 33 is inclined relative to the inner wall 31, so that the opening of the U-shaped cavity gradually narrows. The cavity can provide pre-tightening force when it is used to clamp the insulation sleeve 2.

[0037] A groove is provided on the outer circle of the guide ring 1, and the inner wall 31 is set in the groove. A threaded hole is provided in the groove. A first through hole 311 is provided on the inner wall 31, and the first through hole 311 is corresponding to the threaded hole. The screw 4 passes through the first through hole 311 and is installed in the threaded hole. A second through hole 331 corresponding to the first through hole 311 is provided on the outer wall 33. When using a tool to tighten or loosen the screw, the tool can pass through the second through hole to contact the screw.

[0038] The first through hole 311 can be circular in shape. In this case, the vertical position of the elastic clip 3 and the guide ring 1 cannot be adjusted. If the first through hole 311 is oblong in shape, and the length direction of the oblong shape is the axial direction of the guide ring 1, the vertical position of the elastic clip 3 relative to the guide ring 1 can be adjusted.

[0039] The shape of the second through hole 331 can be the same as that of the first through hole 311.

[0040] The groove depth is equal to the thickness of the inner wall 31. After the elastic clip 3 is fixed to the guide ring 1, the inner wall 31 is flush with the outer circular surface of the guide ring. The insulation sleeve will not be scratched when installing and removing the insulation sleeve, thus improving the life of the insulation sleeve.

[0041] An outer flange 332 is provided on the outer side of the outer wall 33. The flange 332 is close to the outer wall 33 and the transition between the flange 332 and the outer wall 33 is smooth to prevent the edge of the outer wall 33 from damaging the surface of the insulation sleeve when installing and removing the insulation sleeve.

[0042] Four to eight elastic clips 3 are provided at the upper and lower ends of the guide ring 1 to fix the insulation sleeve and provide clamping force.

[0043] The first through hole 311 on the inner wall 31 of the elastic clip 3 at the lower end of the guide ring 1 is a circular hole, and the first through hole 311 on the inner wall 31 of the elastic clip 3 at the upper end of the guide ring 1 is an elongated hole. This allows the lower end of the insulation sleeve 2 to be installed in the elastic clip 3 at the lower end of the guide ring 1 to support the insulation sleeve 2. The elastic clip 3 at the upper end of the guide ring 1 can be adjusted according to the actual position of the upper end of the insulation sleeve 2.

[0044] The above description is merely a specific embodiment of this disclosure, enabling those skilled in the art to understand or implement it. Various modifications to these embodiments will be readily 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 this disclosure. Therefore, this disclosure is not to be limited to the embodiments described herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
