Embodiment 1
[0066] This embodiment provides a reverse-encapsulation bladder vulcanization device, comprising a base 1, a heating jacket 2, a vulcanization mold 3, an upper platen 4 and a vulcanization bladder 6, the upper platen 4 is fixed on the top of the heating jacket 2, the bottom of the heating jacket 2 is connected to the base 1 is fixed, the vulcanization mold 3 is installed in the heating jacket 2, which has the outer surface of the turned-up capsule and the outer surface of the spigot, the vulcanization bladder 6 is installed in the vulcanization mold 3, and has the inner surface of the turned-up capsule and the inner side of the slit On the surface, the heating jacket 2 has a cylindrical structure, and a first flange 24 and a second flange 25 are respectively arranged below and above the cylinder body 21. The cylinder body 21 has a first flow path 201 inside, and the first flow path 201 is L-shaped. The annular flow path communicates with the first inlet 22 and the first outlet ...
Embodiment 2
[0076] The first bladder bend 67 and the second bladder bend 68 in the vulcanization bladder 6 are provided with a support spring 69a, and the support spring 69a is vulcanized and solidified together with the first bladder bend 67 and the bladder second bend 68 .
[0077] A kind of optimized vulcanization bladder 6 is provided in the present embodiment, and support spring 69a is set at two bends of vulcanization bladder 6, and this support spring 69a can provide good resistance to the bend of turn-up capsule in the vulcanization process. The supporting function makes the bending part of the turn-up capsule less likely to be deformed during the vulcanization process. Simultaneously, when the reverse-wrapped capsule is taken and placed, the vulcanizing bladder 6 needs to be stretched, so that the middle part of the capsule body shrinks, which is convenient for taking and placing the reverse-wrapped capsule. Contraction occurs in the middle.
