Tire molds are special equipment used for tire production. They are mainly used for molding and curing rubber materials. They are usually made of high temperature and corrosion resistant materials and have complex shapes to ensure various designs and specifications of tires.

[0003] For example, a tire molding mold with a cooling function disclosed in the patent with announcement number CN218838504U can improve the stability after mold closing, but it does not have the function of step-by-step cooling when the tire is ejected after the mold is opened. Cooling the molded tire helps to avoid adhesion between the tire, the mold and the ejector column. If the lower mold and the ejector column are cooled simultaneously, the ejector column and the tire will be separated and cannot be ejected when the molded tire is ejected from the lower mold, which reduces the use effect.

A strip groove 30 is horizontally provided, and the strip groove 30 is connected with the waist groove 32. A rotating plate 33 is rotatably provided inside the waist groove 32. A rotating rod 16 is fixedly installed on the side end of the rotating plate 33. The surface of the rotating rod 16 passes through the strip groove 30 and the conversion tube 13. The surface of the rotating rod 16 is rotatably installed on the top of the hair dryer 14. A connecting rod 21 is rotatably installed at the bottom of the turntable 2. The ends of the rotating rod 16 and the ends of the connecting rod 21 are both fixedly installed with pulleys 18. The surfaces of the two pulleys 18 are sleeved with belts 17.

The end of the movable rod 25 away from the rack 22 is rotatably installed on the side of the ring 35. A gear 23 is fixedly installed on the end of the connecting rod 21. The gear 23 and the rack 22 are meshed with each other. A slide groove 24 is horizontally provided at the bottom of the turntable 2. A slider 28 is slidably installed inside the slide groove 24. The bottom of the slider 28 is fixedly installed on the top of the rack 22.

[0042] Preferably, after the ejector column 11 is ejected, the direction of the air outlet in the conversion tube 13 can be automatically changed, and further, the air cooling of the lower mold 3 and the cooling of the ejector column 11 can be automatically switched to achieve the selection of air cooling of the lower mold 3 or air cooling of the ejector column 11 at different stages.

[0043] The working principle of the present invention is as follows: after the tire between the corresponding lower mold 3 and the upper mold 4 is formed, the upper mold 4 is driven to move upward by the hydraulic telescopic rod 6, so that the upper mold 4 and the lower mold 3 are opened, and then the rotating column 19 is driven to rotate by the second motor 20, and the rotating column 19 rotates to drive the rotating disk 2 to rotate, and the rotating disk 2 rotates to drive the components thereon to rotate together with the center of the rotating disk 2 as the center;

[0044] During this period, the hair dryer 14 is started synchronously. When the hair dryer 14 is working, the external gas will be discharged from the air outlet pipe 34 through the air inlet pipe. At this time, the wind in the air outlet pipe 34 will enter the conversion pipe 13 through the corresponding opening groove 31 and enter the inside of the three-way pipe 12. It should be noted that the direction in which the wind in the air outlet pipe 34 enters the inside of the conversion pipe 13 is controlled by the sliding column 29. The wind inside the three-way pipe 12 will pass through the air channel 27 to cool the lower mold 3, and further realize the side cooling of the molded tire and the contact side of the lower mold 3, ensuring that when the subsequent ejection column 11 ejects the tire, the tire will not adhere to the lower mold 3, and at the same time, the stability of the ejection column 11 ejecting the tire is also ensured;

[0045] When the lower mold 3 after mold opening rotates to the bottom of the corresponding electric grab plate 9, the second electric telescopic rod 26 drives the collar 35 to move upward, the collar 35 moves upward to drive the top column 11 and the movable rod 25 to move upward, the top column 11 moves upward to drive the molded tire to move upward, so as to eject the tire from the mold, the movable rod 25 moves upward to drive the rack 22 to move horizontally, the rack 22 moves to drive the gear 23 to rotate, the gear 23 rotates to drive the connecting rod 21 to rotate, the connecting rod 21 rotates to drive the pulley 18 and the belt 17 to rotate. The rotation of the pulley 18 drives the rotating rod 16 to rotate, and the rotation of the rotating rod 16 drives the rotating plate 33 to rotate. Due to the setting of the waist-shaped groove 32, the rotating plate 33 rotates and drives the horizontal movement, so that the air outlet pipe 34 can be connected with different ends of the conversion pipe 13, and further, the wind in the air outlet pipe 34 can pass through the conversion pipe 13 and enter the inside of the connecting pipe 15, and the wind in the connecting pipe 15 will enter the inside of the top column 11 and be discharged from the exhaust hole, so that the side of the molded tire and the top column 11 in contact can be cooled, and the adhesion of the tire and the top column 11 can be avoided;

[0046] When the side surface of the tire in contact with the top column 11 is cooled, the electric grab plate 9 is driven by the first electric telescopic rod 8 to move up and down, and the electric grab plate 9 grabs the formed tire to complete the manufacturing of the tire;

[0047] In summary, the tires can be manufactured continuously and quickly by reciprocating in sequence, thereby improving the use effect of the equipment.

[0048] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
