Description
Technical Field
The invention relates to the technical field of lost foam casting, in particular to a gas circuit cleaning buckle.
Background
The lost foam casting is a new process of near-no-allowance and accurate molding, and the process does not need to take out a mold, a parting surface and a sand core, so that the casting does not have flash, burrs and draft angles, and the dimensional error caused by core combination is reduced. The surface roughness of the casting can reach Ra3.2 to 12.5 mu m, the dimensional accuracy of the casting can reach CT7 to 9, the machining allowance is at most 1.5 to 2mm, the cost of machining can be greatly reduced, and compared with the traditional sand casting method, the machining time can be reduced by 40 to 50 percent.
The lost foam casting sand box is generally provided with a casting working cavity and a negative pressure cavity, the negative pressure cavity is vacuumized through a negative pressure machine before casting, so that negative pressure is generated in the negative pressure cavity, sand in the sand box is compacted, the sand box is cooled and contracted along with casting blanks after casting, and the negative pressure cavity releases vacuum, so that the sand in the sand box is loose, and casting blanks are easy to take out. However, when vacuumizing, although a filter screen is used for blocking, a small amount of dry sand enters the negative pressure cavity, and the dry sand entering the negative pressure cavity needs to be cleaned out periodically, at present, the existing air passage cleaning port structure is that a cleaning port is formed in the negative pressure cavity, a flange cover is connected to the outside of the cleaning port, a plurality of bolts are arranged on the flange cover and connected with the negative pressure cavity, and the bolts are required to be detached one by one during cleaning, so that the time and the labor are wasted, and the production efficiency is influenced.
Disclosure of Invention
In order to achieve the above purpose, the invention provides the air path cleaning buckle, which adopts the sealing block and the outer ring which are matched with Morse taper, and the sealing block can be easily ejected out only by screwing the screw in the middle of the cleaning buckle inwards, so that the time and the labor are saved, and the production efficiency is greatly improved.
The technical scheme of the invention is realized as follows:
the utility model provides a gas circuit clearance knot, its characterized in that includes outer loop, sealing piece, screw, the outer loop outside is that a big one is little two cylindrical surfaces are constituteed, is equipped with the interior circular cone hole of morse taper in the centre, and the big end in this interior circular cone hole of morse taper is located big cylindrical surface end, the sealing piece is located in the interior circular cone hole of outer loop morse taper, and the appearance is the outer circular cone face of morse taper with the outer circular cone hole matched with in the morse taper, and the middle part of the big end of this outer circular cone face of morse taper is equipped with the counter bore, and the tip middle part is equipped with the communicating internal thread hole of counter bore, this internal thread hole and screw phase-match, the screw is twisted in the internal thread hole, and the screw rod end top of screw is held on the outer lateral wall of sand box body or diapire.
The large cylindrical surface of the outer ring faces outwards, and the small cylindrical surface is inserted into a cleaning opening on the outer wall of the annular negative pressure cavity or the bottom negative pressure cavity and fixedly connected with the cleaning opening.
Further, the Morse taper outer conical surface of the sealing block is coaxial with the inner counter bore and the inner threaded hole.
Further, the screws adopt hexagon socket head screws of M30-M35.
Furthermore, the Morse taper adopts Morse taper numbers 1 to 3.
The working principle of the invention is as follows: when the lost foam casting sand box works, the sealing block is plugged into the outer ring, the Morse taper is in static fit with a self-locking sealing function, and the sealing block and the outer ring are better sealed by the negative pressure of the negative pressure cavity after vacuumizing; during cleaning, the screw is screwed inwards by using a spanner, and the head of the screw is propped against the outer side wall of the sand box body, so that the sealing block is ejected out, and cleaning work can be performed. By adopting the air circuit cleaning buckle, the sealing blocks are convenient and quick to assemble and disassemble, the working efficiency is greatly improved, and the labor intensity of workers is also reduced.
The beneficial effects of the invention are as follows: simple structure, easy dismounting, work efficiency improves greatly, workman's intensity of labour greatly reduced simultaneously.
