Example 1

[0027] See Figures 1-6 , Figure 1 A schematic diagram of a vulcanizing machine mold changing device has been drawn. As shown in the figure, a vulcanizing machine mold changing device of this utility model includes a top cover 1.

A tooth is fixedly connected to the top end of each of the splined shafts 6. A third bearing 13 is fixedly connected to the center of the upper end face of the wheel 12 and the top cover 1. A rotating shaft 14 is fixedly connected to the inner side wall of the inner ring of the third bearing 13. A connecting frame 15 is fixedly connected to the top of the rotating shaft 14. A gear ring 16, which meshes with the gear 12, is fixedly connected to the outer end of the connecting frame 15. A power mechanism 17 for driving the gear 12 to rotate is provided on the top cover 1. A mold connecting plate 18 is provided on the lower side of the top cover 1. A set of long slots 19 corresponding to the insert block 7 are evenly opened on the mold connecting plate 18. The top cover 1 can be driven to move up and down by the hydraulic cylinder 2, so as to facilitate the replacement of the mold. The gear 12 close to it is driven to rotate by the power mechanism 17. The gear 12 will drive the gear ring 16 to rotate. The rotation of the gear ring 16 will drive all the gears 12, the rotating tube 4 and the spline shaft 6 to rotate, so as to facilitate the replacement of the mold. The combination of a single driving component and a linkage component can reduce costs, reduce the failure rate and facilitate later maintenance.

[0028] The lubrication mechanism 5 includes an oil-collecting ring 501 fixed to the top of the rotating tube 4. An oil storage sleeve 502 is provided on the upper side of the oil-collecting ring 501.

The driving end of the second telescopic cylinder 1702 pushes the connecting block 1703 and the rack 1704 to move. The movement of the rack 1704 will drive the gear 12 to rotate. The rotation of the gear 12 will drive the gear ring 16 to rotate, thereby enabling all the gears 12 and the rotating tube 4 to rotate, and in turn enabling all the spline shafts 6 and the insert block 7 to rotate. A single driving component drives the rotation, which significantly reduces costs and facilitates later maintenance.

[0031] A set of connecting holes 20 are evenly provided on the mold connecting plate 18, which facilitates further fixing of the mold. The connecting holes 20 can cooperate with external connecting parts to fix the mold more firmly on the mold connecting plate 18, making it convenient to change the mold.

[0032] The number of the first bearing 3 and the rotating tube 4 can be four, six or eight; they can be reasonably distributed according to the size and weight of the mold to ensure the stability and balance of the mold during the vulcanization process.

[0033] Working principle:

[0034] This utility model provides a vulcanizing machine mold changing device. During operation: First, the mold connecting plate 18 is connected to the mold in the mold assembly area. Then, the mold and mold connecting plate 18 are placed on the vulcanizing machine. Next, the top cover 1 is moved to the mold opening position above the vulcanizing machine. The top cover 1 is lowered to the target position by the hydraulic cylinder 2. Then, the first telescopic cylinder 11 drives the lifting plate 9, which in turn lowers the third bearing 13, spline shaft 6, and insert block 7. The insert block 7 is inserted into the long slot 19, lowering it to the target position. Then, the driving end of the second telescopic cylinder 1702 pushes the connecting block 1703 and the rack 17. 04. The movement of rack 1704 will drive gear 12 to rotate, and the rotation of gear 12 will drive gear ring 16 to rotate, thereby enabling all gears 12 and rotating tube 4 to rotate, and in turn enabling all spline shaft 6 and insert block 7 to rotate. After insert block 7 rotates to ninety degrees, the mold replacement is completed. When lubrication is required, lubricating oil is added to oil reservoir 502 through oil nozzle 504. The lubricating oil falls into oil collection ring 501 through oil outlet 505, and then enters the friction surface between rotating tube 4 and spline shaft 6 to achieve a good lubrication effect.

[0035] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
