The utility model relates to the technical field of tire manufacturing, and discloses tire vulcanizing equipment. Included angles are formed between first air holes in a center ring seat of the tire vulcanization equipment and the axial direction and the circumferential direction of the center ring seat respectively, guide vanes are located in air injection paths of the first air holes, and the air injection direction coincides with the normal direction of the guide vanes. The structure can accurately guide airflow, gas media are decomposed into axial speed and circumferential speed when flowing through the air holes, the axial speed and the circumferential speed synergistically act on the guide vanes, the guide vanes efficiently rotate, the rotating efficiency is improved, high-temperature gas can be evenly guided to all positions of the inner wall of the curing bladder, it is guaranteed that the interior of the curing bladder is evenly heated, and the service life of the curing bladder is prolonged. Therefore, the vulcanization quality is improved. In addition, the turbulent flow assembly is driven by airflow to rotate passively, uniform circulation of gas is achieved under the condition that an additional power source is not added, the structure of equipment is simplified, the manufacturing cost is reduced, and energy loss is reduced.

The utility model discloses a one-step vulcanization forming die for a joint-free rubber track, and relates to the technical field of rubber tracks. The one-time vulcanization forming mold for the joint-free rubber track comprises a bottom plate, and a forming mechanism and a vibration mechanism are arranged above the bottom plate; the forming mechanism comprises a vulcanizing part and a demolding part; the vulcanization part comprises a vulcanization mold, and the demolding part comprises two demolding sleeves and an ejection ring; the forming mechanism has the technical effects that through cooperative operation of the demolding sleeve, the ejection ring, the limiting rail, the limiting sleeve and other components, on one hand, after a fixing bolt is screwed out, a motor is controlled to drive a threaded rod to drive the ejection ring to automatically eject out the vulcanized rubber track, efficient and convenient demolding is achieved, and the forming mechanism is suitable for large-scale production; the demolding efficiency is greatly improved, the production period is shortened, and the labor cost is reduced; and on the other hand, the limiting structure accurately guides and limits movement of the demolding sleeve, and stable operation of the forming mechanism is guaranteed.

The utility model relates to rubber forming technical field, propose a kind of capsule vulcanizing machine, including frame body;Lifting telescopic part is set on frame body;First sliding frame is vertically slidably arranged on frame body, and lifting telescopic part extension end is connected with first sliding frame;Upper die is set on first sliding frame;Lower die is set on frame body, and after lifting telescopic part extension, upper die is close to lower die and forms vulcanization space;Mold closing telescopic part is set on first sliding frame, after first sliding frame is close to lower die, mold closing telescopic part lengthens, makes mold closing telescopic part extension end and frame body contact, for the upper die is pressed on lower die and forms vulcanization space. Through the above technical scheme, solve the problem that capsule vulcanizing machine hydraulic device is set in the top of prior art and drives upper die to lift, and hydraulic device is vulnerable to damage.

This utility model provides a vacuum tire vulcanizing machine, belonging to the technical field of tire vulcanizing equipment. It includes a tire mold, an upper crossbeam, a support plate, a lower base, a booster cylinder, a vacuum tube, and a vacuum pump. The upper crossbeam is positioned above the lower base, and the upper crossbeam and lower base define a receiving cavity. The booster cylinder is mounted on the lower base, and its drive rod extends into the receiving cavity and connects to the support plate, suitable for driving the support plate to move up and down within the receiving cavity. A first sealing element is provided on the outer side of the support plate, sealingly engaging with the inner wall of the lower base. The support plate, lower base, and upper crossbeam separate a vulcanizing chamber within the receiving cavity. The tire mold is placed within the vulcanizing chamber. One end of the vacuum tube extends into the receiving cavity and communicates with the vulcanizing chamber, while the other end of the vacuum tube is connected to the vacuum pump. This utility model, by setting up a vulcanizing chamber and providing seals at various points, achieves the necessary conditions for vacuum vulcanization, realizing the vacuum function of ordinary molds and improving the quality of tire vulcanization.
