Detailed Description
The technical solution of the present invention is described in detail and fully with reference to the accompanying drawings.
Referring to fig. 1 to 3, the present invention provides a center mechanism of a tire vulcanizer, comprising: an upper disc cylinder 30, an upper disc piston rod 32, an upper disc 23, a lower disc 25, an annular capsule 47, an inlet connection 28 and an outer chamber flow passage 51. An upper disc piston rod 32 is slidably disposed in the upper disc cylinder 30 and extends out from one end of the upper disc cylinder 30. The upper disc 23 is fixedly arranged at one end of the upper disc piston rod 32 which penetrates out of the upper disc cylinder body 30. The lower disc 25 is attached to one end of the upper disc cylinder 30 through which the upper disc piston rod 32 extends, and the lower disc 25 is disposed opposite to the upper disc 23. One end of the capsule 47 is fixedly connected with the upper disc 23, and the other end is fixedly connected with the lower disc 25. The upper disc 23, the lower disc 25 and the capsule 47 enclose a chamber 54. When the upper disc piston rod 32 is retracted toward the interior of the upper disc cylinder 30, the upper disc 23 engages the lower disc 25 in contact, separating the chamber 54 into an inner chamber 48 and an outer chamber 49. An air inlet joint 28 penetrates through the lower disc 25, and the air inlet joint 28 is provided with an air inlet flow channel 50. An outer chamber flow passage 51 is provided in the lower disc 25, the outer chamber flow passage 51 communicating the intake flow passage 50 and the outer chamber 49, the outer chamber flow passage 51 being isolated from the inner chamber 48.
The die 6 is arranged on the outer sides of the upper disc 23 and the lower disc 25, when the die is opened, the upper die 61 of the die 6 is lifted upwards firstly, then the upper disc piston rod 32 can extend out of the upper disc cylinder body 30 to jack the upper disc 23, the capsule 47 is stretched, and the vulcanizing steam enters the outer cavity 49 and the inner cavity 48 from the air inlet joint 28; when the mold is closed, the upper mold 61 moves downward to be engaged with the lower mold 62, the upper disk 23 and the upper disk piston rod 32 move downward, the upper disk 23 contacts the lower disk 25, and the inner cavity 48 and the outer cavity 49 are isolated.
The central mechanism of the tire vulcanizer divides a chamber 54 into two parts through the contact and matching part of the upper disc 23 and the lower disc 25, namely, the chamber is divided into an inner chamber 48 and an outer chamber 49, so that the mold closing tension during tire vulcanization can be greatly reduced, and energy conservation and emission reduction are facilitated. The center mechanism of the tire vulcanizer has the advantages of simple structure and easy operation, and can effectively improve the vulcanizing effect and the production efficiency.
The lower disc 25 is provided with an annular protrusion 55, the protrusion 55 is provided with an annular groove, and a first sealing ring 26 is arranged in the groove. The upper disc 23 has a recess, and when the upper disc 23 is brought into contact engagement with the lower disc 25, the top surface of the projection 55 is brought into contact engagement with the bottom surface of the recess, the first seal ring 26 is compressed between the upper disc 23 and the lower disc 25, and the inner chamber 48 and the outer chamber 49 are separated by the projection 55. The protuberance 55 allows the chamber 54 to be divided into an inner chamber 48 and an outer chamber 49, and once closed, the upper disc 23 is pressed down over the lower disc 25, and then continuing to pass curing steam from the inlet fitting 28, steam enters the outer chamber 49 from the inlet flow passage 50, and the steam from the outer chamber 49 causes the bladder 47 to expand outwardly, forcing the tire carcass to cure. Because the outer cavity 49 belongs to a part of the cavity 54, steam is only introduced into the outer cavity 49 in the tire vulcanization process, and the steam does not need to be introduced into the whole cavity 54, namely, the steam pressure required by vulcanization can be achieved only by introducing less steam, so that the vulcanization effect is ensured, and energy conservation and emission reduction can be realized. The first sealing ring 26 is arranged to ensure that the inner cavity 48 and the outer cavity 49 form a good sealing effect, and leakage between the inner cavity 48 and the outer cavity 49 is avoided, so as to ensure a vulcanization effect. In one embodiment, the first sealing ring 26 is an O-ring.
The outer side surface of the protrusion 55 is a wedge-shaped surface, the inner side surface of the concave portion is a wedge-shaped surface, and when the upper disc 23 is in contact fit with the lower disc 25, the outer side surface of the protrusion 55 is in contact fit with the inner side surface of the concave portion. The wedge-shaped surface can ensure that the contact area is larger, so that the sealing effect is better.
The central mechanism of the tire vulcanizer further comprises an exhaust joint 53 penetrating through the lower disc 25, the exhaust joint 53 is provided with a safety flow channel 52, and the safety flow channel 52 is communicated with the inner cavity 48. After the mold is closed, when leakage occurs in the inner cavity 48 and the outer cavity 49, the vulcanization steam is discharged from the relief flow path 52, and the occurrence of failure is avoided. Before opening the mould, the safety flow passage 52 and the air inlet flow passage 50 are communicated through an external pipeline and a valve, so that the air pressure of the inner cavity 48 and the air pressure of the outer cavity 49 are consistent, and the first sealing ring 26 is prevented from being separated from the groove.
