Abstract
A joint for magnesium alloy casting pump is provided. The joint includes a cylinder and a semicylindrical sleeve, the cylinder hat two sealed ends and is provided with a liquid inlet and a liquid outlet on cylinder wall, the semicylindrical sleeve fits on the cylinder and is movably connected with the cylinder in radial direction, a through hole arranged on the semicylindrical sleeve is communicated with liquid outlet of the cylinder. The joint is simple in structure and convenient for installation. The joint allows casting pipes connected therewith to swing forwards and backwards so as to facilitate entrance of liquid outlet into casting mould, reduce fall between the liquid outlet and bottom plate of mould, reduce impact force of magnesium alloy to mould, and keep stable of liquid level in mould; at the same time, it restricts left and right rotation of casting pipe to prevent molten magnesium alloy from sprinkling outside so as to avoid magnesium alloy waste and mould contamination.
Description
Technical field
The utility model relates to the casting equipment in a kind of magnesium alloy cast technical field, specifically is a kind of magnesium alloy casting pump joint.
Background technology
At present, the end of magnesium alloy cast tubes directly is enclosed within on the leakage fluid dram pipe of casting pump, in the use of reality because so a kind of connected mode makes usually left-right rotation on pipe of cast tubes end, thereby drive cast tubes front end liquid outlet about random pendulum.And the casting gate on the existing mold is laterally narrower, about cast tubes front end liquid outlet disorderly pendulum obviously be unfavorable for accurate casting, result cause liquid magnesium alloy usually to drop on the mould outside and pollute, mold damage.
If the liquid outlet on the cast tubes can stretch in the casting die when casting certainly, in case casting finishes and reintroduces mould, guaranteed that not only liquid magnesium alloy can not drop on the mould outside, can also shorten the drop of liquid outlet and die bottom plate, impulsive force when helping reducing liquid magnesium alloy and falling into mould, keep liquid level in the mould steadily; Just can effectively avoid above-mentioned defective.The raising of liquid outlet can drive by the swing of cast tubes with decline, yet the connected mode between existing cast tubes and casting pump can't realize the swing of cast tubes.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of magnesium alloy casting pump joint, makes the cast tubes of connection on it can swing, and can left rotation and right rotation cause the teeter of front end liquid outlet.
In order to solve the problems of the technologies described above, the main technical schemes of the utility model magnesium alloy casting pump is that it comprises cylinder and semicircle jacket casing, is equipped with inlet opening and fluid hole on cylinder closed at both ends and the barrel; The semicircular cylinder cover is enclosed within on the cylinder, radially flexibly connects with cylinder, and semicircular cylinder puts and is equipped with through hole, is communicated with the fluid hole of cylinder.
The utility model magnesium alloy casting pump can directly be enclosed within on the round exit of existing casting pump with the cylinder inlet opening of joint.Certainly for easy for installation, and the sealing of assurance junction, can be connected to one section feed tube on the inlet opening, be connected also fastening by this feed tube with casting pump round exit.Equally, can be connected to one section drain pipe on the through hole that semicircular cylinder puts, convenience is connected fastening with the end of cast tubes, and guarantees sealing.
Semicircular cylinder of the present utility model is enclosed within the front and back of making certain amplitude on the cylinder when rotating, and the through hole that cylinder fluid hole and semicircular cylinder put is all-pass all the time.Be invariable for the maximum that guarantees the liquid magnesium alloy flow by this joint and flow like this.Because in the reality casting, the too little or instability of flow of liquid magnesium alloy flow in the cast tubes can make the workman can't accurately hold casting time and casting rate, influence casting quality.Fluid hole on the cylinder of the present utility model is greater than the through hole that semicircular cylinder puts.Certainly if making semicircular cylinder put through hole greatly also can realize all-pass than the fluid hole on the cylinder, yet because the restriction of actual cast tubes caliber, it is very big that through hole can not be done, and has been equivalent to reduce semicircular cylinder like this and has been enclosed within rotation amplitude on the cylinder.
The utility model is simple in structure, easy for installation, thereby it makes cast tubes can swing be convenient to liquid outlet and stretches into casting die and carry out casting to shorten the drop of liquid outlet and die bottom plate, impulsive force when helping reducing liquid magnesium alloy and falling into mould, keep liquid level in the mould steadily; It has also limited the left rotation and right rotation that connects the cast tubes on it simultaneously, makes when lifting cast tubes, and liquid magnesium alloy can not drop on the mould outside and cause waste and pollute mold damage because of the unrest pendulum of cast tubes front end liquid outlet; And himself structure can be to the mobile obstruction that causes of the liquid magnesium alloy between casting pump and cast tubes; Be beneficial to carrying out smoothly of whole casting cycle.

The specific embodiment
In conjunction with the accompanying drawings the concrete structure of the utility model magnesium alloy casting pump with joint is further explained.The utility model magnesium alloy casting pump comprises cylinder 2 and semicircle jacket casing 1, is equipped with inlet opening 3 and fluid hole 4 on cylinder 2 closed at both ends and the barrel.Semicircle jacket casing 1 is enclosed within on the cylinder 2, radially flexibly connects with cylinder 2, is equipped with through hole 5 on the semicircle jacket casing 1, is communicated with the fluid hole 4 of cylinder 2.Fluid hole 4 on the cylinder 2 is bigger than the through hole on the semicircle jacket casing 15.Be connected to one section feed tube 6 on the inlet opening 3, convenient fastening by this feed tube 6 with being connected of casting pump round exit, and guarantee sealing.Equally, be connected to one section drain pipe 7 on the through hole 5 on the semicircle jacket casing 1, convenience is connected fastening with the end of cast tubes, and guarantees sealing.
During work, because semicircle jacket casing 1 radially flexibly connects with cylinder 2, when semicircle jacket casing 1 rotated before and after on cylinder 2, fastening also and then swing of cast tubes on it made the liquid outlet of cast tubes front end to move up and down, and passes in and out mould.Certainly when reality is cast, the directly rotation of control semicircle jacket casing 1; But power is provided for rocking back and forth of cast tubes by other mechanisms that are connected with cast tubes, and as the case may be (be generally the distance that cast tubes front end liquid outlet actual needs moves up and down, by die depth decision) control cast tubes rocking tendency within the specific limits.Through hole 5 dropped in the scope of fluid hole 4 all the time when certainly this rocking tendency must guarantee to rotate before and after semicircle jacket casing 1 is on cylinder 2, made both all-pass.Therefore the size of the utility model fluid hole 4 is decided according to the actual requirements.The all-pass of the through hole 5 on cylinder 2 fluid holes 4 and the semicircle jacket casing 1 is invariable for the maximum that guarantees the liquid magnesium alloy flow by this joint and flow.Because in the reality casting, the too little or instability of flow of liquid magnesium alloy flow in the cast tubes can make the workman can't accurately hold casting time and casting rate, influence casting quality.
