Description

Technical Field

[0001] The utility model relates to the field of vulcanization devices, and more specifically to an inner temperature medium injection cylinder head in a vulcanizer. Background Art

[0002] As is well known, the hot water of the inner temperature medium in a B-type vulcanizer is transported through parts such as the central mechanism conveying conduit ring seat and the cylinder head, enters the inside of the capsule through the water inlet provided on the cylinder head, and then discharges from the water outlet provided on the cylinder head, circulating reciprocally, and heating the vulcanized embryo by conduction. There are multiple inner temperature medium water inlet injection ports on the cylinder head, which are evenly distributed circumferentially. The injection ports are designed obliquely in the horizontal and vertical directions to ensure that the medium in the capsule forms a vortex-like circular flow, ensuring relatively uniform heating of each part of the embryo. Through practical temperature measurement and detection, it is found that during the heating and vulcanization process of the embryo, there are problems of uneven heat in the upper and lower parts, large differences, and long-lasting time. There are differences in the rubber vulcanization process, affecting the internal quality and service life of the tire. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides an inner temperature medium injection cylinder head for a vulcanizer, which improves the problems of uneven heat in the upper and lower parts, large differences, and long-lasting time during the heating and vulcanization process of the embryo.

[0004] The technical solution adopted by the utility model to solve its technical problems is: an inner temperature medium injection cylinder head for a vulcanizer, provided with a cylinder head body. The upper side surface of the cylinder head body is processed with an inner temperature medium water inlet cavity and an inner temperature medium water outlet cavity. The inner temperature medium water outlet cavity is communicated with the inner temperature medium water outlet on the cylinder head body. Its characteristic is that the inner temperature medium water inlet cavity is communicated with the inner temperature medium water inlet injection ports evenly distributed circumferentially on the cylinder head body. The inner temperature medium water inlet injection ports include upper water inlet injection ports and lower water inlet injection ports. The inner temperature medium water inlet injection ports are designed obliquely in the horizontal and vertical directions. The upper water inlet injection ports and the lower water inlet injection ports are arranged crosswise. The vertical inclination angle of the upper water inlet injection ports is 18°, the vertical inclination angle of the lower water inlet injection ports is 45°, and the horizontal inclination angles of the upper water inlet injection ports and the lower water inlet injection ports are the same.

[0005] The beneficial effect of the utility model is that the inner temperature medium can enter the upper and lower parts of the capsule simultaneously, making it evenly heated, which is beneficial to improving the internal quality performance and service life of the tire.

[0012] In the figure, for the cylinder head body 4 of the present utility model, an inner temperature medium water inlet cavity 1 and an inner temperature medium water outlet cavity 2 are machined on the upper side surface of the cylinder head body 4. The inner temperature medium water outlet cavity 2 is communicated with the inner temperature medium water outlet on the cylinder head body 4. The inner temperature medium water inlet cavity 1 is communicated with the inner temperature medium water inlet injection ports 3 which are evenly distributed circumferentially on the cylinder head body 4. The inner temperature medium water inlet injection ports 3 include an upper water inlet injection port a and a lower water inlet injection port b. The inner temperature medium water inlet injection ports 3 are obliquely designed in the horizontal and vertical directions to ensure that the medium in the capsule forms a vortex-like circulating flow, guaranteeing relatively uniform heating of each part of the tire embryo. The upper water inlet injection port a and the lower water inlet injection port b are arranged in a cross pattern. The vertical inclination angle of the upper water inlet injection port a is 18°, and the vertical inclination angle of the lower water inlet injection port b is 45°. The horizontal inclination angles of the upper water inlet injection port a and the lower water inlet injection port b are the same. The hot water of the inner temperature medium in the B-type vulcanizer enters the central mechanism conveying conduit and the ring seat to the inner temperature medium water inlet cavity 1 part, and then is sprayed into the inside of the capsule from the inner temperature medium water inlet injection ports 3. The medium in the capsule finally discharges from the inner temperature medium water outlet cavity 2, and circulates reciprocally to heat the inside of the vulcanized tire embryo. The vertical inclination directions of the inner temperature medium water inlet injection ports 3 are divided into two types: the upper water inlet injection port a and the lower water inlet injection port b, so that the water is sprayed to the upper and lower inner sides of the capsule. The upper water inlet injection port a forms a vortex circulation in the lower part of the capsule, and the lower water inlet injection port b forms a vortex circulation in the upper part of the capsule. In this way, the inner temperature medium enters the upper and lower parts of the capsule at the same time, reducing the heating error between the upper and lower parts, narrowing the differences existing in the rubber vulcanization process, and improving the internal quality and service life of the tire.
