Description
Technical field
The utility model relates to a kind of stopper rod structure that realizes metal bath sealing, particularly relates to a kind of stopper rod structure that can realize sealing during for casting of metals.
Background technology
At present, in the casting of metal is produced, what generally adopt is melt to be discharged to from melt case to the device that mould is cast, and controls the executing agency of releasing and can adopt plug valve mechanism.
Two problems below existing in the use of plug valve mechanism:
1, due to the reason such as alignment error, distortion, stopper rod can not clog weif orifice, occurs the phenomenon of leakage;
2, at weif orifice place owing to there being the part metals slagging scorification of solidifying, stopper rod open time, melt weif orifice go out stream not smooth, cause unit interval outflow to change, thereby affect quantitative casting.
Utility model content
Technical problem to be solved in the utility model is to provide a kind ofly can ensure sealing, simultaneously can ensure that again weif orifice is smooth and easy to realize the stopper rod structure of the metal bath realized sealing of melt quantitative casting.
In order to solve the problems of the technologies described above, the stopper rod structure of the metal bath the realized sealing that the utility model provides, the upper end of sleeve is connected with drive unit, the lower end of described sleeve is connected with the upper end of stopper rod, the lower end of described stopper rod is connected with chock plug, and described chock plug is inserted in weif orifice weif orifice is realized to sealing.
The lower end of described sleeve is sleeved on the upper end of stopper rod, the upper end of described stopper rod is provided with radial direction through hole, the lower end of described sleeve is provided with at least one radial location hole, and fastening nuts is fixed and used to the radial direction through hole of the radial location hole of bolt by described sleeve and described stopper rod by both relative positions.
On described sleeve, be processed with at least two group radial location holes of axially-aligned, each described certain distance of radial location span, makes stopper rod axially can adjust flexibly in sleeve like this.
The upper diameter of described stopper rod is less than the lower end diameter of bore of described sleeve, when described stopper rod is contained in described sleeve by described bolt, between described stopper rod and described sleeve lining, exist certain gap, chock plug can have certain deflection angle like this, in the time of the weif orifice described in jam-pack, there is automatic positioning action, realize excellent sealing effect.
Described chock plug is conical, increases and the sealing effectiveness of described weif orifice, and the top of described chock plug is provided with round bar, and the end of described round bar is concordant with the end of described weif orifice, for removing the metal slagging scorification of weif orifice.
Adopt the stopper rod structure of the metal bath the realized sealing of technique scheme, drive unit (as cylinder, hydraulic cylinder) and relative being fixedly connected with of sleeve, drive sleeve moves up and down.Jacket casing is on stopper rod, and the top of stopper rod is processed with radial direction through hole, is also processed with one group of positioning through hole in the axial direction of sleeve, and the distance that each through hole interval is certain can adjust the length of stopper rod in sleeve, to adapt to the needs of drive unit stroke flexibly.Bolt connects both by the through hole of sleeve and stopper rod.Owing to there being certain gap between sleeve endoporus and stopper rod, just make chock plug have the flexibility of certain angle beat, thereby in the time there is installation and distortion inaccuracy, can make chock plug have automatic positioning action in the time of jam-pack weif orifice, ensure the sealing of chock plug.
Meanwhile, at round bar of top design of stopper rod head, its end is concordant with weif orifice end, and when chock plug moves down jam-pack weif orifice, push rod can be removed the metal slagging scorification of weif orifice, ensures the unimpeded of weif orifice.
The utility model will solve in existing casting of metals production, plug valve mechanism is because the reason such as alignment error and distortion produces leakage, and part metals is in the problem that goes out head piece slagging scorification, be that one can ensure sealing, can ensure again weif orifice stopper rod structure smoothly simultaneously, realized melt quantitative casting.
Of the present utility model simple in structure, deft design, low cost of manufacture, the installation of system, practicality, easy to maintenance.By the application in actual production, prove the sealing that really can play guarantee chock plug of this utility model, make the effect that weif orifice is unimpeded.
