[ detailed description ] embodiments

In order to deepen the understanding of the present invention, the present invention will be further described in detail with reference to the following embodiments and the attached drawings, and the embodiments are only used for explaining the present invention, and do not constitute the limitation to the protection scope of the present invention.

Referring to the attached drawings 1-3, the utility model provides a novel split type gas furnace end, which comprises a furnace end main body 1, a first ejection pipe 2 and a second ejection pipe 3, wherein the furnace end main body 1 comprises an air cavity part 4 and a sealing cover plate 5 for sealing the air cavity part 4, the first ejection pipe 2 and the second ejection pipe 3 are arranged at the front end of the air cavity part 4 and are communicated with the air cavity part 4, the sealing cover plate 5 is connected and sealed with an opening 6 at the back of the air cavity part 4, the first ejection pipe 2 and the second ejection pipe 3 are cast and integrally formed, the split type gas furnace end is manufactured by adopting the structure, the length of the ejection pipes can be completely reserved, so that the design is more reasonable, the ejection length of the ejection pipes is prevented from being shortened by adopting the split type structure, the reasonable design size, shape and effect of the ejection pipes are ensured more easily, in addition, the split type structure is adopted, the sealing performance is better, and the air leakage problem is not easy to occur.

The joint of the air cavity part 4 and the sealing cover plate 5 is provided with a sealing gasket, the sealing gasket can not only enhance the sealing performance, but also prevent the sealing cover plate 5 from directly contacting with the air cavity part 4, and the combination unevenness of the air cavity part 4 caused by the uneven surface of the cover plate during die casting is avoided. The sealing cover 5 is provided with a projection corresponding to the size of the opening 6, which is fitted into the interior of the chamber portion 4, thereby further enhancing the sealing effect.
