[0053] A tire mold and vulcanizing machine quick positioning structure, including the lower hot plate 2 on the vulcanizing machine and the tire mold 1, the precise positioning structure is equipped between the lower hot plate 2 and the tire mold 1, and the precise positioning structure specifically includes the centering ring 3 arranged at the center of the lower hot plate 2 and the positioning cone 4 arranged at one side of the positioning ring, and the number of positioning cones 4 is at least one.

[0054] The bottom of the tire mold 1 is provided with a positioning structure matched with the centering ring 3 and the positioning cone 4, and the positioning structure is specifically a positioning guide hole 5 matched with the positioning cone 4 and a positioning step matched with the centering ring 3, and finally the position positioning of the tire mold 1 and the vulcanizing machine can be realized through the centering ring 3, and the circumferential positioning of the tire mold 1 and the vulcanizing machine can be realized through the positioning cone 4.

[0055] Generally, the height of the positioning cone 4 is higher than that of the positioning ring, and when the tire mold 1 is matched with the vulcanizing machine, the circumferential positioning is first realized through the positioning cone 4, and then the precise positioning between the tire mold 1 and the vulcanizing machine is further realized through the centering ring 3.

[0056] In order to avoid the problem that after the tire mold 1 is placed on the vulcanizing machine, it is troublesome and laborious to adjust due to incorrect position, the utility model is provided with an upper positioning part on the side wall of the tire mold 1, and a lower positioning part is arranged on the lower hot plate 2, and the positioning position of the lower positioning part and the upper positioning part is higher than that of the precise positioning structure, so that the installation of the tire mold 1 is guided and positioned in advance by using the upper positioning part and the lower positioning part, and the subsequent adjustment troubles caused by the positioning cone 4 and the centering ring 3 located at the bottom of the tire mold 1 and inconvenient to observe are reduced.

[0057] The number of upper positioning parts is at least two, and the number of lower positioning parts is consistent with that of upper positioning parts, and the plurality of upper positioning parts are preferably distributed in a circle to further improve the precision of pre-positioning.

[0058] The utility model discloses a lower heat plate 2 center still is equipped with the center mechanism of being able to lift, and the positioning position of lower positioning part and upper positioning part is higher than the top position of center mechanism that has not lifted, thereby avoid the situation that tire mold 1 is installed or disassembled in the process on vulcanizing machine, because the impact to vulcanizing machine center mechanism of separating accurate positioning structure leads to, guarantee the safety and stability of center mechanism.

[0059] Embodiment one:

[0060] As Figures 1 to 7 The utility model discloses a lower heat plate 2 center still is equipped with the center mechanism of being able to lift, and the positioning position of lower positioning part and upper positioning part is higher than the top position of center mechanism that has not lifted, thereby avoid the situation that tire mold 1 is installed or disassembled in the process on vulcanizing machine, because the impact to vulcanizing machine center mechanism of separating accurate positioning structure leads to, guarantee the safety and stability of center mechanism.

[0061] Lower positioning part includes several color blocks, preferably uses circular color block, and color block can be set on lower heat plate 2 through mechanical processing or pasting etc., and several color blocks are arranged along the radial direction of lower heat plate 2, and its specific position is reasonably arranged according to different tire mold 1 size.

[0062] The light column of laser 10 of upper positioning part is located in the color block of lower positioning part, can guarantee the deviation of tire mold 1 relative vulcanizing machine to be in the range that can be corrected of positioning cone 4, centering ring 3.

[0063] When actual tire mold 1 is hoisted to the upper side of vulcanizing machine, the hoisting tire mold 1 and the lower heat plate 2 of vulcanizing machine can not be parallel due to the length of lifting belt, the unevenness of forklift shovel, but because the bottom of cooperation seat 7 and the concave spherical surface are spherical surface cooperation, laser 10 is set in the bottom of cooperation seat 7 and still maintains vertical state under the action of gravity, and the position deviation of light column on lower heat plate 2 is not too big due to the deflection of tire mold 1, thereby guaranteeing that light column can still play the role of mold position orientation. Of course, the offset angle of laser 10 will be limited by the size of through hole 9, so the aperture of through hole 9 can be appropriately increased, so that the offset of laser 10 meets certain demand, and the offset angle a range allowed by the above structure of the embodiment is preferably 0-12 °.

[0064] In addition, the support block 6 and the tire mold 1 are preferably connected by the magnetic block 8, which can meet the requirements of manual quick disassembly. Of course, other detachable structures such as positioning pins or connecting bolts can also be connected to the tire mold 1. When facing different specifications of tire molds 1, the pasting position of the color block and the thickness of the magnetic block 8 can be adjusted to quickly meet the use requirements.

[0065] Embodiment two:

[0066] AsFigures 8 to 16 As shown, the upper positioning portion of this embodiment includes a guide plate 11, which is preferably directly fixed to the outer side wall of the tire mold 1, and an upper guide structure is provided on the guide plate 11;

[0067] The lower positioning part includes a guide column 13, the height of which is greater than the height of the centering ring 3, the positioning cone 4 and the top of the unraised center mechanism. A lower guide structure is provided on the guide column 13, and the upper guide structure can cooperate with the guide column 13 or the lower guide structure on the guide column 13 in the vertical direction.

In this embodiment, the guide structure is set as a guide hole 12, and the guide hole 12 can cooperate with the guide column 13. The top of the guide column 13 is set as a cone, so as to facilitate the cooperation with the guide hole 12.

[0070] The diameter of the guide hole 12 can be larger than the diameter of the guide column 13, as long as it can guide the positioning cone 4 to cooperate with the positioning structure at the bottom of the tire mold 1. This is because the upper end of the positioning cone 4 is itself conical. When the tire mold 1 falls on the vulcanizer, even if the center line of the positioning cone 4 does not coincide with the center line of the positioning guide hole 5 at the bottom of the tire mold 1, the center line of the positioning cone 4 only needs to correspond to the bottom of the positioning guide hole 5 of the tire mold 1 to meet the correction requirements.

[0071] The guide hole 12 can also be set as an oblong hole, and the setting direction of the oblong hole is consistent with the radial direction of the tire mold 1. This structure can avoid interference or jamming when at least two guide holes 12 cooperate with the guide column 13, and provides a certain adjustment space for the guidance of the two.

[0072] This embodiment utilizes the cooperation of the guide hole 12 and the guide column 13, which is easy to manufacture. The rough positioning between the tire mold 1 and the vulcanizer can be completed in advance through the cooperation of the two. This not only avoids the collision between the tire mold 1 and the center mechanism, but also pre-guides the precise guide structure of the tire mold 1 and the vulcanizer in advance.

[0073] Example 4:

[0074] like Figures 11 to 13 As shown, the parts that are the same as those in the second embodiment are not repeated. In this embodiment, the upper guide structure is provided as an upper guide groove 14 that passes vertically through the outer side of the guide plate 11. The width of the upper guide groove 14 gradually decreases along the direction close to the center of the tire mold 1, and finally the upper guide groove 14 forms a structure similar to a trapezoidal groove or a triangular groove. In this embodiment, the upper guide groove 14 is preferably a trapezoidal groove.

[0075] The lower guide structure is set as a trapezoidal column 15, the horizontal cross-section of the trapezoidal column 15 is trapezoidal, the trapezoidal column 15 matches the shape of the upper guide groove 14, and the trapezoidal column 15 is arranged on the side of the second guide column 13 close to the center of the lower hot plate 2. In this way, when the trapezoidal column 15 cooperates with the upper guide groove 14, three positioning surfaces will be formed, so that the trapezoidal column 15 and the upper guide groove 14 can be roughly positioned in the radial and circumferential positions.

[0076] In this embodiment, the three surfaces of the trapezoidal column 15 close to the lower hot plate 2 are all configured as inclined surfaces, so as to facilitate the guidance of the trapezoidal column 15 and the upper guide groove 14 during the initial engagement.

[0077] Embodiment 5:

[0078] like Figures 14 to 16 As shown, the parts that are the same as those in Example 2 are not repeated. In this embodiment, the guide structure is configured as a transverse rod 16 arranged at the outer end of the guide plate 11. The transverse rod 16 can rotate relative to the guide plate 11. Tapered rollers 17 are provided at both ends of the transverse rod 16. The outer side of the tapered roller 17 is configured as a small diameter end. The two tapered rollers 17 form a shuttle-like shape.

[0079] The corresponding lower guide structure is set as a lower guide groove 18, which is arranged on the side of the guide column 13 close to the center of the lower hot plate 2. The groove walls on both sides of the lower guide groove 18 are consistent with the inclination angle of the tapered surface of the tapered roller 17. When the upper guide structure and the lower guide structure are guided together, the tapered surfaces of the two tapered rollers 17 will roll in contact with the inclined groove walls on both sides of the lower guide groove 18, thereby reducing the friction between the two and reducing the probability of jamming.

[0080] The inner walls of the lower guide groove 18 are all configured as tapered surfaces to facilitate the guidance of the two tapered rollers 17 when initially mated with the lower guide groove 18 .

[0081] This embodiment is similar to the fourth embodiment, and both achieve radial positioning of the tire mold 1 and the vulcanizer through two groove walls, and also achieve circumferential positioning of the two.
