Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Fig. 2, a kind of central mechanism of vulcanizing machine positioning sleeve comprising top board 1, lower clamp plate 2, capsule 3, cylinder
4 and positioning sleeve 5.
As shown in Fig. 2, lower clamp plate 2 is fixed on vulcanizer 6, the top of lower clamp plate 2 is arranged in top board 1, with lower folder
Plate 2 is horizontally disposed；Capsule 3 is cylindrical in shape, and both ends are sealedly connected on top board 1, on lower clamp plate 2 respectively, capsule 3 with
Top board 1, lower clamp plate 2 surround a closed airbag chamber 31.
The cylinder body 41 of cylinder 4 is mounted on side of the lower clamp plate 2 far from capsule 3, as shown in Fig. 2, the piston rod 42 of cylinder 4
