One end is equipped with connecting flange, and the outlet side of the sleeve is close by end cap and the sealing ring being set between the end cap and casing
The end face of envelope, the connecting flange is equipped with rubber slab, and driving described sleeve pipe is equipped between the connecting flange and the end cap
The air spring of axially outward movement, the sleeve is interior to be equipped with the resetting spring for acting on described sleeve pipe, the air inlet of the sleeve
End is equipped with vacuum tube jointing.
Lost foam casting vacuum suction connector provided by the utility model, as further setting, the connection method
Orchid include with regulating flange sleeve integrally formed body flange and connect by adjusting bolt with the body flange, it is described
Air spring is set in described sleeve pipe between the body flange and the end cap, and the rubber slab is arranged in the tune
It saves on flange.
Lost foam casting vacuum suction connector provided by the utility model, as further setting, described sleeve pipe position
It is equipped with baffle ring in the pipeline section in the sleeve, the resetting spring, which is set in described sleeve pipe, is located at the end cap and the gear
Between circle.
Lost foam casting vacuum suction connector provided by the utility model, as further setting, described sleeve pipe with
It is additionally provided with guide collar between the end cap.
Compared with prior art, the utility model has the advantages that：
1, easy to use and reliable, sandbox can be made accurately and reliably to be connect with vacuum tube in cast, at the end of cast and energy
Make sandbox and vacuum tube quick separating；
2, simple in structure, convenient maintenance and replacement, spare part is few.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The utility model is further described below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, a kind of lost foam casting vacuum suction connector, including sleeve and casing 4, the left-hand end of sleeve be into
Gas end, right-hand end are outlet side, and vacuum tube jointing 2 is connected on the inlet end of sleeve, and the left-hand end of casing 4 stretches into set
In cylinder, right-hand end is stretched out out of sleeve to be connect with connecting flange.Specifically, connecting flange by with 4 integrally formed ontology of casing
Flange and the composition of regulating flange 8 being threadedly coupled by adjusting bolt with body flange.The outlet side of sleeve is by end cap 5 and sets
The sealing ring 6 being placed between end cap 5 and casing 4 seals, and rubber slab 9 is equipped on the end face of regulating flange 8, upper in casing 4
It is equipped with the air spring 10 of 4 axially outward movement of drive sleeve between body flange and end cap 5, is equipped in sleeve and acts on set
The resetting spring 3 of pipe 4,10 deflation rear sleeve 4 of air spring can reset under the action of resetting spring 3.
In the present embodiment, the left-hand end of casing 4 is equipped with baffle ring, resetting spring 3 be set on casing 1 be located at end cap 5 with
Between baffle ring.
In the present embodiment, guide collar 7 is additionally provided between casing 4 and end cap 5, sleeve is fixedly mounted in mounting base 1.
The utility model lost foam casting vacuum suction connector when in use, after air extraction connector is assembled first positioned on
Opposite sandbox suction interface at, make suction interface on sandbox and rubber slab 9 at a distance of 20~30mm, by vacuum pipe with it is true
Blank pipe jointing 2 connects.Compressed air is filled with when cast in air spring 10, air spring 10 rises, and resetting spring 3 is pressed
Contracting, makes rubber slab 9 be bonded with the suction interface on sandbox, the compressing rubber plate 9 under the action of air spring 10, forms sealing,
The control switch on vacuum tube is opened, negative pressure is formed in sand, completes cast；After cast, the control on vacuum tube is closed
Switch releases the compressed air in air spring 10, and rubber slab 9, casing 4 and air spring 10 are under the action of resetting spring 3
It resets, sandbox is made to be separated with rubber slab 9.
Above example is only to the exemplary description of this patent does not limit its scope of protection, people in the art
Member can also be changed its part, as long as it does not exceed the essence of this patent, within the protection scope of the present patent.
