Description

Technical Field

[0001] The utility model belongs to the technical field of internal temperature jet accessories of vulcanizers, and particularly relates to a steam jet cover plate of a vulcanizer. Background Art

[0002] With the development of tire companies, the demand for accelerating tire vulcanization time is also increasing. Since the cylinder heads of existing vulcanizers are all adapted to the superheated water process and cannot meet the existing nitrogen process, the internal temperature jet nozzles of the cylinder heads adapted to the central mechanism cannot spray to the position where condensed water is stored in the vulcanization bladder, resulting in the upper sidewall temperature being normal and the lower sidewall temperature being low. The measured upper and lower temperature difference is about 25. In this case, changing the vulcanization process to increase the steam time and the condensation removal time cannot meet the requirements. The existing temperature difference is likely to cause a large difference in the vulcanization degree of the upper and lower sidewalls of the tire, which will also affect the performance of the tire. Summary of the Invention

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a vulcanizer steam injection cover, which can effectively reduce the excessive temperature difference between the upper and lower sides of the vulcanizer during the vulcanization process, ensure the stable performance of the upper and lower sidewalls of the tire and correspondingly reduce the vulcanization time of the tire.

[0004] In order to achieve the above technical objectives, the technical solution adopted by this utility model is:

[0005] A vulcanizing machine steam injection cover plate, which includes a cover plate body, a connecting hole is provided in the center of the cover plate body, a cover plate cavity is provided on the periphery of the connecting hole, the cover plate cavity extends outward in the plane of the connecting hole along the radial direction of the cover plate body, a drain outlet is provided on the top of the cover plate cavity, a plurality of groups of raised portions are equidistantly provided in the circumferential direction on the cover plate body around the cover plate cavity, screw holes are provided on the raised portions, and a plurality of injection holes are provided between two adjacent raised portions.

[0006] Preferably, in the vulcanizer steam jet cover plate, the height of the cover plate cavity is 117 mm-123 mm.

[0007] Preferably, in the vulcanizer steam jet cover, a ring structure is formed between the multiple equidistantly arranged protrusions and the outer periphery of the cover body.

[0008] Preferably, in the vulcanizer steam jet cover plate, two recessed portions and a connecting portion are provided between the annular structure and the cover plate cavity along the circumferential direction of the cover plate body, and the connecting portion is provided between the two recessed portions.

[0009] Preferably, in the vulcanizer steam jet cover plate, a transition section is provided between the two recessed portions, and ends of the transition section are respectively connected to the annular structure and the outer periphery of the cover plate cavity.

[0010] Preferably, in the vulcanizer steam jet cover, the recessed portion extends longitudinally in the circumferential direction of the cover body, and the recessed portion has a depth of 95 mm to 110 mm.

[0011] Preferably, in the vulcanizer steam injection cover plate, the injection holes are arranged on the outer periphery of the annular structure corresponding to the recessed portion, and the injection holes are communicated with the recessed portion.

[0012] Preferably, in the vulcanizing machine steam injection cover plate, the injection holes are inclined holes with an inclination of 20-50 degrees.

[0013] Preferably, in the vulcanizer steam jet cover plate, the drain port extends in the longitudinal direction in the circumferential direction of the cover plate cavity, and the drain port has a groove depth of 4-6 mm.

[0014] The beneficial effects of the technical solution provided by the embodiment of the utility model are:

[0015] (1) The steam injection cover plate of the vulcanizer of the present invention has a safe and reliable structure and is easy to install. By increasing the injection port of the cylinder head and optimizing the internal temperature injection angle, the steam can be directly injected to the bottom of the lower tire sidewall. The steam can also be used to stir the condensed water accumulated in the vulcanizing capsule, thereby accelerating the discharge of the condensed water from the drain hole and reducing the temperature difference between the upper and lower parts of the vulcanizer. The reduction of the temperature difference between the upper and lower parts of the vulcanizer can appropriately shorten the vulcanization time and improve the workshop output.
