Arriving, the tire quality that frequently can lead to vulcanize is poor, and overlap etc. is more.And fluid pressure type vulcanizer is for meeting overall matched moulds pressure
Power, sets up one and adds compressing cylinder at its top, relies on the flexible of oil cylinder to pressurize mould, thus meets the life of tyre vulcanization
Production. art.At four mould fluid pressure type vulcanizers, when pressurized cylinder is arranged on bottom vulcanizing chamber, for avoiding central authority, on market big portion
Divide and use double pressurized cylinder or many pressurized cylinder, the most often bring a problem, in pressure process, can be because manufacturing and missing
The series of problems such as difference or installation, can cause moulding pressure between pressurized cylinder to equalize, thus whole when causing mould matched moulds
Face discontinuity equalization, reduces the quality of production of tire.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of pressurized cylinder for four mould vulcanizers, it solves
The unbalanced problem of pressure between pressurized cylinder.
For solving above-mentioned technical problem, this utility model be the technical scheme is that
A kind of pressurized cylinder for four mould vulcanizers, it is characterised in that: comprise center piston bar, cylinder barrel, piston, dust-proof
Circle, piston seal, back-up ring, upper cylinder cover and lower cylinder cap, cylinder barrel is the tubular type cylinder that upper and lower two ends are not closed, and upper cylinder cover is fixed
In cylinder barrel upper end, lower cylinder cap is fixed on cylinder barrel lower end, upper cylinder cover and lower cylinder cap and has in oil inlet and outlet, upper cylinder cover and lower cylinder cap
Between have the vertical through hole mated with center piston bar, center piston bar is slidably arranged in vertical through hole and can be along perpendicular
Clear opening slides in upper cylinder cover and lower cylinder cap, and back-up ring, piston seal and dust ring are indecisive and changeable in being successively set on from inside to outside
Stopper rod is with in the gap of upper cylinder cover and lower cylinder cap, and piston is fixed on outside center piston bar and is slidably arranged in inner wall of cylinder
On.
Further, a through hole, hole size and vulcanizer center machine are had in the middle of described center piston bar vertically
Structure external diameter mates.
Further, described upper cylinder cover and lower cylinder cap are staged cylinder cap, and the big step diameter of cylinder cap is equal with cylinder barrel external diameter,
The little step diameter of cylinder cap is mated with internal diameter of cylinder, and the little ladder of cylinder cap is fixing in inserting cylinder barrel.
Further, described oil inlet and outlet is L-type pipeline, and pipeline one end is arranged on outside upper cylinder cover or the big ladder of lower cylinder cap
On face, the pipeline other end is arranged on the downside of upper cylinder cover or on the upside of lower cylinder cap.
Further, described piston is weldingly fixed on center piston bar.
Further, described dust ring upper end is provided with the lug edge that horizontally outward side extends, and lug is along covering
Upper cylinder cover or lower cylinder lid surface.
This utility model compared with prior art, has the following advantages and effect: pressurized cylinder is set directly at vulcanizer
The outside of central authority or the center piston bar of pressurized cylinder is sheathed is fixed on outside central authority, so directly uses one and adds
Cylinder pressure, solves the problem that multiple pressurized cylinder pressure cannot equalize, and pressurized cylinder is easy for installation simply.
Accompanying drawing explanation
