Abstract

The utility model is that suction pouring inhales the pneumatic clamping lock of casting chamber cap sealing fastening.In antigravity casting as suction pouring casting mold must vacuum state, be all placed on now using casting mold in the suction casting room of sealing and molten iron is aspirated from ladle by stretching out outdoor stalk fill type.Being sealed with using screw clamp flange for suction casting chamber cap, also has using cylinder or oil cylinder press, the former can not be applicable batch production, and the device of the latter is more complicated.Now it can make clamping lock hook lock Zhu Xizhu rooms lower floor flange using the pneumatic clamping lock of lid installation on casting room is inhaled, control cylinder, realize sealing, simplify the complex mechanism of support suction casting room levels sealing stress.

Description

Suction pouring inhales casting chamber cap sealing and fastens pneumatic locking mechanism

Technical field

A kind of pneumatic structure of casting industry antigravity casting suction pouring chamber cap sealing fastening.

Background technology

Continuing to use gravity-assist pouring method in foundary industry always is molded liquid metal, recently as casting requirement increasingly Height, gravity-assist pouring method can not meet the quality requirement of casting, occur anti-gravity pouring process again, complicated to thin type piece Part and thickness differ greatly part, undoubtedly timely, anti-gravity pouring to mold-filling capacity, feeding capacity, and casting into Product rate suffers from evident characteristic.But the suction pouring of anti-gravity pouring must make casting mold be in vacuum state, make mould cavity and iron Water level establishes pressure differential, and molten iron can overcome gravity to be inhaled into mould cavity, therefore casting mold is previously positioned in suction casting room, inhales casting Room typically point upper and lower two floor, upper strata is equipped with suction mouth, flat-rammer and vacuum meter etc., and lower floor is casting mold rest area, have stalk, Thermal insulation layer and sealing of a mould structure.When extracting air after inhaling casting room levels and covering, it is necessary to sealing is kept, except upper and lower covers Between have outside seal, levels will be also in close contact.Levels are most to be connected for flange, useful screw fastening, such as a small amount of examination System, but be not easy to produce in batches, to production of reaching the standard grade in batches, then use air-or liquid-operated and compress upper lid.The thrust of upper lid must expire Sufficient die mould and flange seal, lower floor must fix, and can bear to cover tightly close compression fitting, therefore be all lower floor in production of reaching the standard grade It is fixed, do not move up and down, closure or openness action is done by upper lid, lower floor architecturally, and will keep same with the position of upper lid The heart is aligned, while stalk is carried out suction casting into ladle.Therefore the levels installation framework for inhaling casting room all seems non- It is often complicated.

Utility model content

Using a kind of pneumatic clamping lock, and installed in inhaling on the circumference of flange covered on casting room, it is driven by the cylinder, makes on suction casting room Lower floor can be brought into close contact, and lower floor is no longer fixed with framework to bear the thrust of upper lid, inhale only control to inhale during casting and cast what is covered Mobile and lifting, and control the action of clamping lock.

The technical solution of the utility model is that suction pouring inhales the pneumatic locking mechanism of casting chamber cap sealing fastening, on casting room is inhaled Six deciles are equipped with clamping lock seat on the circumference of flange of lid, and bearing pin is housed in the hole of clamping lock seat extending area, clamping lock, clamping lock are housed on bearing pin Can do more than 45 ° swings in clamping lock seat, the tapered end of clamping lock lower end can hook lock Zhu Xizhu rooms lower floor flange bottom, the swing rod of clamping lock End is connected with cylinder piston rod end toggle with holes with bearing pin, on the toggle support member and suction casting room Shang Gai peripheries bucket wall of tail cylinder Toggle connected with bearing pin, the air inlet-outlet pipe of cylinder and inhale casting room top of the upper layer electromagnetic switch valve module and be connected, unitized substructure Air inlet-outlet pipe be connected with source of the gas.

It is motionless that remarkable result of the present utility model is that Xi Zhu rooms lower floor places above ladle, when casting mold is put into suction casting room After lower floor, inhale lid alignment Xi Zhu rooms lower floor closure on casting room and no longer pressurize in place, but will by inhaling the pneumatic clamping lock covered on casting room The upper and lower close clamping sealing of flange, so that it may start vacuum suction and carry out inhaling casting and fill type, simplify the structure of Xi Zhu rooms lower floor, no It must be exerted a force simultaneously to inhaling casting room levels closure, as long as making lid on suction casting room to pinpoint mobile and lifting.
