[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-5 A bladder vulcanizer comprises a bladder vulcanizer 1 and a core mold 2, wherein the core mold 2 is detachably connected to the output end of the bladder vulcanizer 1, and the steam equipment of the bladder vulcanizer 1 is connected to the core mold 2 through an upper metal hose 3, a hard pipe 4 and a lower metal hose 5. The upper metal hose 3 can be connected to the steam equipment, and the hard pipe 4 is fixed to the bladder vulcanizer 1 through a bracket 6 and a pipe clamp 7. The lower metal hose 5 is connected to the core mold 2 through a quick-release connector 8;

[0024] The quick-release connector 8 includes a cannula 81 and a sleeve 82. The cannula 81 is inserted into the sleeve 82. The cannula 81 is connected to the lower metal hose 5. The sleeve 82 is connected to the core mold 2. An annular groove 83 is provided on the sleeve 82. A compression spring 84 is provided in the annular groove 83. A sliding sleeve 85 is connected to the compression spring 84. The sliding sleeve 85 is slidably connected in the annular groove 83. A plurality of balls 86 are movably connected in the side wall of the sleeve 82 located at the annular groove 83. A trapezoidal annular groove 87 is provided on the outer wall of the cannula 81. Several balls 86 are all located in the trapezoidal annular groove 87.

[0025] By connecting the upper metal hose 3 and the lower metal hose 5 at both ends of the hard tube 4, and setting the quick-release joint 8, the core mold 2 does not need to be removed from the pipeline when it is removed and replaced, and the operation is simple, safe and reliable. The quick-release joint 8 realizes the rapid connection and separation between the core mold 2 and the lower metal hose 5, making the replacement of the core mold 2 more convenient and quick. After the core mold 2 is separated from the output end of the capsule vulcanizer 1, the sliding sleeve 85 is pressed downward to form a vertical dislocation between the sliding sleeve 85 and the ball 86. The ball 86 loses the restraint of the inner hole of the sliding sleeve 85, and the cannula 81 is pulled out from the sleeve 82. The inclined surface of the annular groove 87 guides the ball 86 to expand outward, so that the insert tube 81 can be smoothly pulled out of the sleeve 82, and the insert tube 81 and the sleeve 82 can be separated, thereby realizing the separation of the pipeline between the lower metal hose 5 and the core mold 2. During installation, the sleeve 85 is pressed again to make the ball 86 lose the tendency to be squeezed. After the insert tube 81 is inserted into the sleeve 82, the sleeve 85 is released. Under the action of the rebound force of the compression spring 84, the sleeve 85 produces an inward squeezing force on the ball 86, so that the ball 86 is pressed against the trapezoidal annular groove 87, realizing the connection between the insert tube 81 and the sleeve 82.

[0026] Specifically, in this embodiment, a sealing structure 9 is provided in the insert tube 81 and the sleeve 82. The sealing structure 9 includes a first positioning ring 91, a second positioning ring 92, a sealing spring 93 and a tapered plug 94. The first positioning ring 91 and the second positioning ring 92 are both connected to the inner wall of the pipe. One end of the sealing spring 93 is connected to the first positioning ring 91, and the other end is connected to the tapered plug 94. The tapered plug 94 is inserted into the second positioning ring 92, so that when the insert tube 81 is separated from the sleeve 82, the tapered plug 94 can achieve a sealing effect on the pipe to prevent steam leakage during the replacement process, and when the insert tube 81 is inserted into the sleeve 82, the two tapered plugs 94 contact each other, so that the two sealing springs 93 are compressed, and a gap for steam to flow is generated between the tapered plug 94 and the second positioning ring 92.

[0027] Specifically, in this embodiment, the insert tube 81 is connected to the lower metal hose 5 via the clamp 10 , thereby achieving a detachable connection between the insert tube 81 and the lower metal hose 5 .

[0028] Specifically, in this embodiment, the sleeve 82 is threadedly connected to the top end of the core mold 2 through the external thread 11, thereby achieving a detachable connection between the sleeve 82 and the core mold 2.

[0029] Specifically, in this embodiment, the outer wall of the end of the inserting tube 81 away from the connection with the lower metal hose 5 is tapered, so that the inserting tube 81 can smoothly generate an outward thrust for pushing the ball 86 when plugged into the sleeve 82.

[0030] Specifically, in this embodiment, the single-sided cross-section of the sliding sleeve 85 is vertically T-shaped, with larger apertures at the upper and lower ends and a smaller aperture in the middle. The upper and lower ends are respectively slidably fitted on the upper and lower outer walls of the sleeve 82, and the middle part is slidably fitted on the outer wall of the annular groove 83. The upper end provides a limit for the sliding sleeve 85 to prevent the sliding sleeve 85 from separating under the elastic force of the compression spring 84 and to ensure accurate contact between the sliding sleeve 85 and the ball 86.

[0031] Specifically, in this embodiment, the sleeve 82 is provided with a plurality of sliding holes 88 on the side wall of the annular groove 83, and each ball 86 is located in a corresponding sliding hole 88. The aperture of one end of the sliding hole 88 located on the outer wall of the annular groove 83 is the same as the diameter of the ball 86, and the aperture of the other end located on the inner wall of the sleeve 82 is smaller than the diameter of the ball 86, thereby preventing the ball 86 from separating from the sleeve 82 and ensuring that the ball 86 can slide smoothly and separate from the trapezoidal annular groove 87 when expanding outward.

[0032] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
