Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below.
It should be noted that, when the vulcanizer of the present invention vulcanizes a green tire, a high-pressure vulcanizing medium needs to be connected, the vulcanizing medium of the present invention is preferably pure nitrogen, and the pressurized gas used by the gas pressurizing mechanism of the present invention is a high-pressure vulcanizing medium (i.e., high-pressure nitrogen) used when the new energy vulcanizer vulcanizes a green tire, so the present invention can fully utilize the existing high-pressure vulcanizing medium to realize pressurization, and has the advantages of small occupied space, high efficiency and environmental protection.
As shown in fig. 1 to 11, the present invention discloses a central mechanism 1 suitable for a new energy vulcanizer, which comprises a stretching mechanism for stretching an inflatable bladder; and a demolding mechanism for separating the vulcanized tire from the lower mold; and a gas pressurizing mechanism 10 for pressurizing the lower mold during tire vulcanization, wherein the gas pressurizing mechanism utilizes a vulcanizing medium (such as pure nitrogen) used in the case that the bladder is inflated by the new energy vulcanizing machine to realize pressurization.
Specifically, the gas pressurizing mechanism 10 of the present invention includes a cylinder 11, a piston 12 sealed with the cylinder 11, a lower heat insulator 13, and a lower electric heating plate 14; wherein, the cylinder 11 is provided with an air inlet 112 and an air outlet 113, and the lower heat insulator 13 and the lower electric heating plate 14 are sequentially disposed on the upper portion of the piston 12. The piston 12 is arranged in the cylinder 11 and forms a sealed chamber 15 with the cylinder 11, the piston 12 can reciprocate up and down relative to the cylinder 11 after being stressed, and when the high-pressure pure nitrogen filled in the chamber 15 reaches a certain amount, the piston 12 moves upwards under the pressure of the high-pressure nitrogen; after the pure nitrogen in the chamber 15 is exhausted, the piston 12 returns to the initial position under its own weight, i.e. falls back to the bottom of the cylinder 11.
Alternatively, the piston 12 of the gas pressurizing mechanism 10 of the present invention may be made of a heat insulating material, i.e., the piston also functions as a lower heat insulating member, and the lower electric heating plate is disposed at the upper portion of the piston, so that the same function can be achieved by using only the piston, thereby reducing the height of the gas pressurizing mechanism 10.
The central mechanism 1 of the present invention further comprises a mold adjusting mechanism 40 for adjusting the position of the lower mold after replacing different lower molds, so as to be suitable for the vulcanization operation of tires with different specifications. Therefore, a threaded hole 111 is formed in the middle of the cylinder 11, and the threaded hole 111 is used for connecting the cylinder 11 and the mold adjusting mechanism 40 on the center mechanism 1. Specifically, the mold adjusting mechanism 40 is disposed below the cylinder 11; the mold adjusting mechanism 40 comprises a base 41 and a flange stud 431 fixedly arranged on the base 41; the internal thread of the threaded sleeve 432 is connected with the flange stud 431, the external thread of the threaded sleeve 432 is connected with the threaded hole 111 of the cylinder 11, and a gear structure 432A is arranged on the threaded sleeve; and the first driver 421 drives the threaded sleeve 432 to rotate relative to the flange stud 431 and the threaded hole 111 of the cylinder 11 through a first transmission mechanism 422 (such as a gear assembly) and a gear structure 432A, so as to adjust the vertical position of the gas pressurization mechanism 10 and match the heights of lower molds with different specifications. The configuration structure realizes secondary distance adjustment through relative rotation of the threaded sleeve 432 and the threaded hole 111 and relative rotation of the threaded sleeve 432 and the flange stud 431, has a large adjustable distance range, and does not influence the overall height setting of the central mechanism 1.
As another embodiment, as shown in fig. 11, a rotatable flange stud 432 may be further disposed on the base, for example, a rotating shaft (not shown) is disposed at a lower portion of the flange stud to achieve a rotating function of the flange stud, a gear structure 432A is disposed on the flange stud, and the threaded hole 111 is in threaded connection with the flange stud 432; and then the first driver 421 drives the flange stud and the threaded hole 111 to rotate relatively through the first transmission mechanism and the gear structure 432A, so as to realize one-time adjustment of the upper and lower positions of the gas pressurization mechanism 10, and match with lower dies of different specifications.
In addition, because the bottom of the cylinder 11 of the invention is provided with the air inlet 112 and the air outlet 113, the air inlet 112 is connected with the high-pressure nitrogen through the air pipe to form an air inlet pipeline (not shown), the air outlet 113 is connected with the air pipe to form an air outlet pipeline (not shown), and the air inlet pipeline is a branch of a high-pressure vulcanizing medium (pure nitrogen) passage used when the new energy vulcanizing machine inflates the capsule, the invention can directly utilize the high-pressure nitrogen of the new energy vulcanizing machine for pressurization. When the capsule is filled with high-pressure pure nitrogen gas, the gas pressurizing mechanism 10 is pressurized through the gas inlet hole 112 at the same time or alternatively; after the pressurization is finished, the air inlet pipeline is communicated and closed through an air outlet pipeline connected with the exhaust hole 113, so that the vulcanizing medium is exhausted to realize pressure relief.
As shown in fig. 5 to 7, the piston 12 of the present invention has a first sidewall 121 (i.e., a sidewall of the threaded hole 111) and a second sidewall 122 (i.e., a sidewall of the cylinder 11) close to the cylinder 11, the first sidewall 121 is provided with a first sealing groove 123, the second sidewall 122 is provided with a second sealing groove 124, and first and second sealing rings (not shown) are provided in the first and second sealing grooves 123 and 124, so that the chamber 15 is sealed during pressurization.
In addition, the second side wall 122 of the cylinder 11 of the present invention is further provided with a pressure relief hole 114, a distance from the pressure relief hole 114 to the cylinder bottom 115 is H, and the distance H is greater than or equal to a pressurization stroke of the gas pressurization mechanism. The reason is that the gas pressurizing mechanism 10 is used for supporting the lower mold 5, when the tire is vulcanized, the upper mold 4 moves downwards to the lower mold to close the mold and cover the green tire (not shown), and if the upper mold does not move downwards in time or the pressurizing mechanism is filled with a vulcanizing medium for pressurizing due to misoperation in the vulcanizing process, the piston 12 moves upwards until being separated from the cylinder 11, so that the potential safety hazard is caused. Therefore, by providing the relief hole 114, when the piston 12 moves upward to the lower bottom surface 125 of the piston 12 beyond the relief hole 114, the gas in the chamber 15 is exhausted through the relief hole 114, the chamber 15 is no longer a closed space, and the piston 12 does not further move upward, thereby ensuring safe operation.
Further, in order to make the cylinder body better bear the pressure and the gravity of the upper and lower molds, a reinforcing rib 116 is arranged at the bottom of the cylinder body.

Preferably, the present invention further comprises a fixed connector 23, and the demolding mechanism comprises a third driver 27 and a lower ring assembly; the lower ring assembly comprises a lower ring 221 and a central member 222 for supporting the lower ring, the central member 222 is sleeved outside the upper ring support rod 212, one end of the central member 222 is connected with the fixed connecting piece 23, the other end of the central member 222 is connected with the lower ring 221, and the upper ring support rod 212 can move up and down relative to the central member 222 under the action of the second moving device; in addition, the second driver 241, the second transmission mechanism 242, the lead screw nut 252 and the third driver 27 are fixedly arranged at the lower part of the fixed connecting piece 23, the upper part of the fixed connecting piece 23 is connected with the central part 222, the third driver 27 can drive the fixed connecting piece 23 to move up and down, and then the central part 222 drives the upper ring 211 and the lower ring 221 to synchronously move up and down, so as to realize the demoulding action after the vulcanization of the green tyre.
As shown in fig. 1 and 13, the present invention further discloses a new energy vulcanizing machine 100 (only a single-station new energy vulcanizing machine is taken as an example for illustration, and the principles of the double stations and the multiple stations are the same), which comprises a frame 2 for supporting and fixing various functional components; the upper die assembly 3 is arranged on the rack 2 and can move up and down, the upper die assembly comprises an upper heat-insulating cover 6, and an upper electric heating plate (not shown), an upper heat-insulating piece (not shown) and an upper die 4 which are arranged in the upper heat-insulating cover 6, and the upper electric heating plate and the upper heat-insulating piece are sequentially arranged from the heating side (namely the outer side) of the upper die 4 to the top direction of the upper heat-insulating cover 6; the lower die 5 is arranged corresponding to the inner side of the upper die 4, and a vulcanization chamber is formed after the upper die and the lower die are assembled; and the center mechanism 1 provided with the gas pressurizing mechanism 10 is adopted, and the lower die is arranged on the gas pressurizing mechanism 10 of the center mechanism 1.
