Description
Technical field
The utility model relates to the vulcanizing equipment for the production of tire, relates in particular to a kind of driving water vat for mould emptier.
Background technique
Existing vulcanizer mould emptier mostly is Lever type; mainly formed by water vat bearing, driving water vat, lever and bearing support; rotate around bearing support by driving the water vat driving lever, move up and down thereby drive to encircle under the central authority, cooperate other action to finish tire and deviate from from counterdie smoothly.The gland and the piston rod that drive water vat are motive sealing, leakage phenomenon can appear after long-term the use, the seal form of existing water vat adopts the combination seal of co-axial seal circle, height lip sealing ring, O type circle and piston support ring more, though this seal form can play certain sealing effect, can be to the serious shortening effective sealing time in the situation that water quality is relatively poor or environment is comparatively abominable.In addition, because the attendant is in short supply, safeguard the in advance inefficacy that also can cause sealing not in place.If occur to leak and can only change seal ring, but it is consuming time longer to change many seal rings, the normal production that this must have influence on tire has increased production auxiliary time, has reduced manufacturing efficiency, be manufacturer do not wish to see.
The model utility content
The technical problem that the utility model mainly solves provides a kind of driving water vat that is used for mould emptier that can conveniently adjust and change seal arrangement.
For solving the problems of the technologies described above; the technological scheme that the utility model adopts is: a kind of driving water vat for mould emptier is provided; comprise cylinder body; front end housing; gland and piston rod; described cylinder body and front end housing link together; be provided with a through hole at the center of front end housing; described gland is from the outside of cylinder body to being embedded in this through hole; be provided with center hole at gland; described piston rod is located in the cylinder body and by this center hole and is stretched out the cylinder body outside; described through hole is enclosing protruding lip near extending to the inside one on the end face of cylinder interior; described protruding lip upper support has a guide bush; be provided with V-type folder fabric seal ring between described guide bush and the gland, the support by described V-type folder fabric seal ring makes the upper-end surface of gland be higher than the upper-end surface of front end housing, between gland and front end housing, be provided with for the stationary gland position screw; the nut compressing of described screw is on gland, and the screw thread of screw can screw in the screw of front end housing.
Wherein, the upper-end surface of described gland is extended a circle flange laterally, has the gap between the lower surface of described flange and the upper-end surface of described front end housing, has screw hole on the flange, and described screw passes this screw hole and screws in the screw of front end housing.
Wherein, described guide bush is provided with a circle groove at the surface of contact with described through hole, is provided with support ring in the described groove.
Wherein, described gland is provided with annular groove at the surface of contact with described piston rod, is provided with the piston rod support ring in the described annular groove.
Wherein, the inwall near the gland upper-end surface on the described gland is provided with the dustproof groove of a circle, is provided with dust ring in the described dustproof groove.
The beneficial effects of the utility model are: in the equipment using process, leak if produce between cylinder body and the piston rod, only need screw-driving, make gland extruding V-type folder fabric seal ring produce distortion by it, thereby be close to piston rod, eliminate the gap between gland and the piston rod, guarantee sealing; When water vat uses for a long time and adjust the vanishing of rear final adjusting play, if leakage problem again occurs, as long as add one section suitable V-type folder fabric after pulling down screw and gland, just can make water vat again possess good sealing, the regular maintenance of equipment is simple and easy to do, reduced the auxiliary time of producing, avoided greatly having saved the cost of production of enterprise because plant maintenance causes stopping work to cause damage.
