Abstract
The invention discloses a self-sealing casting bent pipe for low-pressure tilting casting. The self-sealing casting bent pipe comprises a bent pipe body. One end of the bent pipe body is connected with an alloy liquid sealing device through a fixing flange, and the other end of the bent pipe body is connected with a casting mold through a sprue flange. The sprue flange is provided with a flange connecting face connected with a sprue of the casting mold in a matched mode. An annular groove extending in the circumferential direction of the flange connecting face is formed in the flange connecting face. A rotating component is installed at the bottom of the annular groove. The rotating component is connected with an annular sealing part and enables the annular sealing part to freely rotate. The annular sealing part is partially embedded into the annular groove in a stuffed mode in the height direction of the annular sealing part, and partially protrudes out of the flange connecting face. According to the technical scheme, the run-out phenomenon during casting can be effectively avoided, the problems that due to the fact that in the prior art, a sealing part needs to be replaced manually in time after each workpiece is cast, continuous casting cannot be carried out, and material consumption is large are solved, and meanwhile potential safety hazards are reduced.
Description
Technical field
The present invention relates to a kind of self sealss cast bend pipe, be specifically related to a kind of cast of the self sealss for low pressure tilted casting bend pipe.
Background technology
Low pressure tilted casting is the one of low pressure casting, be liquid metals under lower gas pressure effect, fill the die cavity of full sand mold, then the certain angle that verts, make running gate system upwards, to form a kind of method of foundry goods.Its technical process is: in the crucible (or hermetically sealed can) of sealing, pass into dry gas by air inlet pipe, metal liquid in crucible (or hermetically sealed can) is under the effect of gas pressure, rise along stalk, enter reposefully in the die cavity of sand mold by the vert running gate system of self sealss cast bend pipe and sand mold of low pressure, keep gas pressure to the sand mold on the interior liquid level of crucible (or hermetically sealed can) to vert after certain angle, make running gate system upwards, remove the liquid level gas pressure of metal liquid, make not solidified metal liquid in stalk pass back into crucible (or hermetically sealed can), take again foundry goods away.
Low pressure tilted casting, has acted on the advantage of low pressure casting, is in particular in the following aspects: 1, to fill type more steady for liquid metals; 2, casting forming is good, is conducive to form the foundry goods of clear-cut, any surface finish, more favourable for the shaping of large thin-wall or casting of complicated structure; 3, foundry goods dense structure, mechanical performance is high; 4, improved the product yield of product, generally running gate system is rising head after verting.Except above-mentioned advantage, the more conventional low pressure casting of low pressure tilted casting also has the advantage that productivity ratio is high, and conventional low pressure casting need to, after foundry goods solidifies completely, could pressure relief be taken foundry goods away, consuming time longer; And low pressure tilted casting only need complete by type be filled, keep pressure to sand mold to vert, make running gate system upwards, without treating casting solidification, can pressure relief take foundry goods away.In addition, working condition is good; Equipment is simple, easily realizes mechanization and automation, is also the outstanding advantages of this casting technique.
Chinese invention patent CN 101480717 B disclose multipurpose cast liquid-lifting component and the casting equipment with this assembly, wherein have the associated description for low pressure tilted casting.
At present, the self sealss cast bend pipe that low pressure tilted casting uses is now all without self-sealing function, while adopting low pressure tilted casting technique, need manually on cast gate flange (with the mating surface of sand mold cast gate), be placed with the mat of sealing function, thereby prevent that " runout " phenomenon from appearring in liquid metals while verting with sand mold in cavity filling process, this mat need to be changed afterwards in time every cast, and causing pouring into a mould cannot be continuous, and the problem of high material consumption, meanwhile, also there is certain potential safety hazard.
Summary of the invention
The object of this invention is to provide a kind of cast of the self sealss for low pressure tilted casting bend pipe that has self-sealing function, can effectively prevent from pouring into a mould time, there is " runout " phenomenon, and need the artificial seal of changing in time after having solved every the cast existing in prior art, thereby that causes cannot continuous pouring and the problem of high material consumption, has reduced potential safety hazard simultaneously.
To achieve the above object of the invention, the technical solution used in the present invention is: a kind of cast of the self sealss for low pressure tilted casting bend pipe, comprise bend pipe body, one end of described bend pipe body connects aluminium alloy sealing device by mounting flange, the other end of described bend pipe body connects casting mold by cast gate flange, described cast gate flange has the flange connection surface being connected with the cast gate of described casting mold, on described flange connection surface, be provided with the annular groove circumferentially extending along it, the bottom land of described annular groove is provided with rotary part, described rotary part is connected with lip ring and described lip ring is rotated freely, described lip ring is embedded in described annular groove along its short transverse part filling, part protrudes from described flange connection surface.
Further technical scheme, described annular groove is the two rank grooves that comprise base channel and top slot, and described rotary part is installed in described base channel, and described lip ring filling is embedded in described top slot.
Further technical scheme, described base channel is rectangular channel, described top slot is dovetail groove.
Further technical scheme, described mounting flange is connected with the cast bell of described aluminium alloy sealing device, described mounting flange and vertical setting of described cast gate flange.
Further technical scheme, described self sealss cast bend pipe also comprises reinforcement gusset, described reinforcement gusset is fixedly connected with described bend pipe body.
Further technical scheme, described rotary part is thrust ball bearing or ring rail motion.
Further technical scheme, described lip ring is packing ring.
Further technical scheme, described aluminium alloy sealing device is crucible or hermetically sealed can.
Because technique scheme is used, the present invention compared with prior art has following advantages: the cast of the self sealss for low pressure tilted casting bend pipe involved in the present invention, playing on the basis of the function that prevents low pressure tilt pouring " runout ", can make seal be rotated with verting of casting mold, therefore significantly reduce the replacing operation of seal, realize the continuous production of low pressure tilted casting, improving production efficiency, reduce material consumption, reduce potential safety hazard, therefore practicality is better, is easy to apply, and has larger practical value.
