Detailed Description

The present application is described in further detail below with reference to figures 1-2.

The central mechanism of vulcanizer among the correlation technique includes vertical setting piston rod 3, and piston rod 3 is from up being equipped with in proper order down and goes up to fit with a contraceptive ring cylinder body 2, fit with a contraceptive ring and go up cylinder cap 1, ejecting subassembly 4.

The embodiment of the application discloses vulcanizer central mechanism lower ring mechanism integral type. Referring to fig. 1 and 2, the vulcanizer central mechanism lower ring mechanism integrally includes a sealing groove 11 formed on an inner side wall of the upper ring upper cylinder head 1, a sealing member disposed in the sealing groove 11, a gland 5 bolted to the upper ring upper cylinder head 1 for compressing the sealing member, and the piston rod 3 slidably penetrates through the gland 5 and the sealing member.

Referring to fig. 1 and 2, the sealing groove 11 extends to a side of the upper ring cylinder cover 1 facing away from the upper ring cylinder body 2, and the gland 5 extends into the sealing groove 11. The operator places the seal in the seal groove 11 and then bolts the gland 5 to the upper ring upper head 1. The gland 5 extrudes the sealing element, the sealing element is deformed under pressure, so that an extrusion force is applied to the piston rod 3, the piston rod 3 and the sealing element are relatively tight, and the possibility of fluid leakage is low.

Referring to fig. 1 and 2, when the vulcanizing machine is in operation, the piston rod 3 and the seal slide relatively, the seal is worn, and a gap is generated between the seal and the piston rod 3. Because the upper ring upper cylinder cover 1 and the gland 5 are fastened and connected through the bolts, an operator can adjust the tightness degree of the bolts to control the deformation degree of the sealing element, so that the sealing element can be always ensured to clamp the outer side wall of the piston rod 3.

Referring to fig. 1 and 2, the sealing element comprises a plurality of sealing rings 6 which are parallel and closely attached to each other, and a connecting line between the plurality of sealing rings 6 is parallel to the axis of the piston rod 3. Because the connection between sealing member and the piston rod 3 is inseparabler, consequently operating personnel once only sheathes piston rod 3's process with whole sealing member more difficult, splits the sealing member into a plurality of sealing washer 6, compares whole sealing member, and the process that single sealing washer 6 sheathes piston rod 3 realizes more easily.

Referring to fig. 1 and 2, a ring-shaped supporting ring 7 is placed at one end of the sealing groove 11 facing the upper ring cylinder body 2, the supporting ring 7 faces one side of the gland 5, one side of the gland 5 used for extruding a sealing element, and the sealing ring 6 are respectively arranged in a V shape, and the tip of the V shape is back to the upper ring upper cylinder cover 1.
