Description
Technical field
The present invention relates to Technology of EPC field more particularly to a kind of gas circuit cleaning buttons.
Background technology
Lost foam casting be a kind of Near net shape, precise forming new process, the technique without modulus, without die joint, nothing
Sand core, thus casting does not have overlap, burr and pattern draft, and reduce due to core combination and caused by scale error.Casting
Part surface roughness is up to Ra3.2 to 12.5 μm;Casting dimension accuracy is up to CT7 to 9;Allowance is up to 1.5 to 2mm,
The expense that mechanical processing can be greatly reduced is compared with traditional sand mould casting method, it is possible to reduce during 40% to 50% mechanical processing
Between.
Lost foam casting sandbox is generally equipped with foundry work chamber and negative pressure cavity, and the effect of negative pressure cavity is that cast is preceding by negative
Press vacuumizes, and negative pressure cavity is made to generate negative pressure, and sand inside sandbox is compacted, as slab cooling is shunk after cast, negative pressure cavity
Vacuum is discharged, makes sand in sandbox loose, is easy to take out strand.But when vacuumizing, though there is filter screen blocking, still have a small amount of dry
Sand enters negative pressure cavity, these dry sands entered must periodic cleaning come out, at present, existing gas circuit cleaning mouth structure is negative pressure cavity
On open a clean-up port, one blind flange of connection, blind flange are connect equipped with multiple bolts with negative pressure cavity outside clean-up port, cleaning
When these bolts need to be removed one by one, it is very time-consuming laborious, influence production efficiency.
Invention content
To achieve these goals, the present invention provides a kind of cleanings of gas circuit to detain, which is coordinated using Morse's taper
Sealing block and outer shroud, need to will only clear up the intermediate screw of button and tighten inside, it is possible to easily eject very much sealing block, time saving province
Power substantially increases production efficiency.
The technical proposal of the invention is realized in this way：
A kind of gas circuit cleaning button, it is characterised in that be small one and large one two circle outside the outer shroud including outer shroud, sealing block, screw
Cylinder forms, and centre is equipped with Morse's taper inner circle taper hole, and the big end of the Morse's taper inner circle taper hole is set on big cylindrical surface end, institute
Sealing block is stated in outer shroud Morse's taper inner circle taper hole, shape is bored for Mohs matched with outer shroud Morse's taper inner circle taper hole
It is outside one's consideration circular conical surface, counterbore is equipped in the middle part of the Morse's taper outer conical surface big end, the internal thread communicated with counterbore is equipped in the middle part of small end
Hole, the internal thread hole match with screw, and the screw is screwed into internal thread hole, and it is external that the screw end head of screw is held in sandbox sheet
On side wall or bottom wall.
Outwardly, small cylindrical surface is inserted into the cleaning on annular negative pressure cavity or bottom negative pressure cavity outer wall on the big cylindrical surface of outer shroud
Mouth is simultaneously fixedly connected.
Further, the Morse's taper outer conical surface of the sealing block and interior counterbore, internal thread hole are coaxial.
Further, the screw uses the socket head screw of M30~M35.
Further, the Morse's taper uses Morse's taper No. 1~No. 3.
The operation principle of the present invention：When lost foam casting sandbox works, sealing block is filled in outer shroud, Morse's taper is quiet to match
Conjunction has self-locking seal function, and vacuumizing the negative pressure of rear negative pressure cavity makes sealing block preferably be sealed with outer shroud；During cleaning with spanner to
Interior stubborn screw, and screw head is held on sandbox outer body wall, so as to which sealing block be ejected, it is possible to carry out fettler
Make.It is cleared up and detained using this gas circuit, dismounting sealing block easily, quickly, is greatly improved work efficiency, also reduced simultaneously
The labor intensity of worker.
The beneficial effects of the invention are as follows：Simple in construction, easy to disassemble and assemble, working efficiency greatly improves, while the labour of worker
Intensity substantially reduces.
