Abstract
The utility model relates to a kind of fettling installations, including a gentle rifle of bending tube body, the bending part of bending tube body opens up an air gun eye, and air gun eye connects air gun, for air gun blowing direction towards a bending edges tube body export direction of bending tube body, another bending tube body of bending tube body is intracavitary towards type.Its structure is simple, easy to use, can effectively clear up the intracavitary loose sand of lower loam core rear profile, combine and do not damage loam core structure.
Description
Technical field
The utility model relates to a kind of casting tooling, specifically a kind of fettling installation.
Background technique
The casting structure of some complexity needs to fill multiple loam cores under to complete moulding, tight by core print fit clearance and sand
Solidity influences, under complete loam core rear profile is intracavitary can generate some loose sands, conventionally employed air gun is directly blown sand, and sand removal effect is limited, and
In the presence of the hidden danger for blowing bad loam core.
Summary of the invention
In view of the deficiencies of the prior art, it is simple to provide a kind of structure for the utility model, easy to use, can effectively clear up down
The intracavitary loose sand of loam core rear profile, combines the fettling installation for not damaging loam core structure.
The technical solution adopted in the utility model is: a kind of fettling installation, it is characterised in that: gentle including a bending tube body
Rifle, the bending part of bending tube body open up an air gun eye, and air gun eye connects air gun, a bending of the air gun blowing direction towards bending tube body
Another bending tube body of side tube body export direction, bending tube body is intracavitary towards type.
The bending angle of the bending tube body is greater than 0 degree and is less than 180 degree.
The bending tube body is L shape tube body.
One bending tube body of the bending tube body exports upper external loudspeaker shape outlet.
Another bending tube body of bending tube body is intracavitary towards type is protruded into, gone out through air gun eye towards bending tube body by air gun
It mouthful blows, loose sand can be sprayed from the intracavitary suction of narrow type and by outlet, it is low to operate convenient, save the cost, labor intensity,
And bending angle can be selected according to type cavity structure, adjust the thickness of bending tube body according to cavity wall thickness, meet different cavity bottoms
The sand removal operation of loose sand, sand removal effect is good, and protrudes into direction, position for another bending tube body of loose sand position adjustment bending tube body
It sets and carries out inhaling sand, do not damage loam core structure, it is advantageously ensured that casting quality.
Detailed description of the invention
Fig. 1 is that the utility model uses structural schematic diagram.
In figure: type chamber 1, loam core 2, L shape tube body 3, air gun eye 4, air gun 5, flaring exit 6.
Specific embodiment
It is described further below in conjunction with drawings and examples.
Shown in Fig. 1, a kind of fettling installation includes L shape tube body 3, air gun 5, flaring exit 6.One quadrature tube of L shape tube body 3
Body protrudes into 1 inner mold chamber 1 of type chamber in the gap of loam core 2, and the right angle of L shape tube body 3 opens up air gun eye 4, connects air gun on air gun eye 4
5, the blowing direction of air gun 5 towards L shape tube body 3 another right angle tube body export direction, another right angle tube body of L shape tube body 3
Outlet on external loudspeaker shape outlet 6.
Above-described embodiment bending tube body is L shape tube body, for loose sand in the gap of vertical direction upper impression 1 and loam core 2 into
Row inhales sand,
Bending angle can be selected according to type cavity structure, adjust the thickness of bending tube body according to cavity wall thickness, be adjusted
At sand removal operation, in scope of protection of the utility model.
