Problems solved by technology

However, sometimes because the cylinder head presses the sealing ring too tightly, the lifting resistance of the center rod will be very large. If the pressure is too loose, the gap between the cylinder head and the ring seat will be too large, and the internal pressure steam cannot It is completely ejected from the steam hole in the cylinder head, thus affecting the overall performance of the tire curing press

Abstract

The invention discloses a sealing device for a central mechanism of a tire vulcanizing machine. The sealing device comprises a central rod, an annular base and a cylinder cover, wherein the annular base and the cylinder cover are arranged on the central rod in a sleeving manner; a thread bushing is arranged on the central rod; a thread corresponding to the thread bushing is arranged in an inner circle of the cylinder cover; the thread bushing is in screw joint on the cylinder cover. According to the sealing device provided by the invention, the thread bushing is arranged on the central rod, and meanwhile, the thread corresponding to the thread bushing is arranged in the inner circle of the cylinder cover, so that the compression amount of a sealing ring between the central rod and the annular base can be adjusted; when the lifting resistance of the central rod is overlarge or a clearance exists between the cylinder cover and the annular base, the problems can be solved by only rotating the thread bushing; compared with the prior art, the sealing device has the advantages that the lifting resistance of the central rod and the clearance between the cylinder cover and the annular base can be effectively overcome, so that the overall performance of the tire vulcanizing machine can be ensured.

Description

technical field [0001] The invention relates to the technical field of tire vulcanizing machines, in particular to a sealing device for a central mechanism of a tire vulcanizing machine. Background technique [0002] In the installation of a sealing device for the central mechanism of a tire vulcanizer, in order to ensure the sealing performance of the cylinder, a sealing ring needs to be arranged between the central rod and the ring seat of the cylinder. However, sometimes because the cylinder head presses the sealing ring too tightly, the lifting resistance of the center rod will be very large. If the pressure is too loose, the gap between the cylinder head and the ring seat will be too large, and the internal pressure steam cannot It is completely ejected from the steam hole in the cylinder head, thus affecting the overall performance of the tire vulcanizing machine. Contents of the invention [0003] In order to solve the above technical problems, the present inventio...
