Abstract
The utility model discloses a kind of sandbox for iron sand moulding.Sandbox casing uses cavity structure, and back-plane design has passage, can be blown into pneumatics wind into sandbox by passage, realizes the rapid cooling of workpiece, closes down pneumatics wind, and cavity structure turns into thermal resistance, realizes the slow cooling of workpiece, meets the production requirement of high-abrasive material casting.The utility model can control the cooling velocity of workpiece, can produce the high-abrasive material workpiece of high quality, improve the production efficiency and qualification rate of wear-resisting workpiece.
Description
Technical field
The utility model is applied to casting field, and in particular to a kind of sandbox for iron sand moulding.
Background technology
In high-abrasive material casting field, the cooling velocity of casting is relevant to the performance of workpiece, especially impact flexibility.Improve
The cooling velocity of high-abrasive material molten metal, is advantageous to crystal grain thinning, increases the number of nuclei of carbide, so as to improve high-abrasive material
Impact flexibility.Iron Mould Coated Sand is that one layer of resin sand is sticked in the die cavity of the metal mold of steel and iron manufacturing, changes the thickness of resin sand
Degree can change the cooling velocity of molten metal, but this technique can not adjust the cooling velocity of wear resistance castings.Cast for high-abrasive material
Wish that cooling velocity is fast for part, during solidification, be advantageous to crystal grain thinning, wish that cooling velocity is slow after solidification, to reduce workpiece not
With the thermograde between position, avoid cracking.
Patent of the inventor in Application No. 2016110839159《A kind of iron sand shell moulded casting method》Carried in application material
A kind of form following mold box has been arrived, the sandbox is used for iron sand moulding, moulding in the shell mould embedment iron sand for specifically making precoated sand,
Cooling water cavity is devised in the sandbox, using water cooling iron sand is cooled down, so as to improve the solidification cooling of casting, metal
Liquid solidification after cut off the water, due to the conductive force of water, molten metal solidification after cooling velocity it is still very fast, casting be also easy to produce split it is useless.
The content of the invention
The utility model solve technical problem be：The cooling velocity of wear resistance castings is controlled, rapid cooling during solidification, is satisfied with
Tissue, slow cooling after solidification, to reduce stress, improve product qualification rate.
Technical scheme is used by the utility model：
The casing of the iron sand shell mould sandbox is made using iron and steel material quality, and casing includes interior plate, upper plate, outer panel, upper bottom
Plate and lower shoe, cavity are formed after above-mentioned component combination, the outer panel has air inlet pipe, and the upper plate has passage.
Further, in order to improve cooling effect, the passage is distributed in whole upper plate.
Further, in order to prevent iron sand from falling into cavity, the upper plate（5）Upper tiling filter screen（8）.
What the utility model obtained has the technical effect that：
Shell mould is used i.e. pourable after iron sand moulding in sandbox, is blown into compressed air into cavity from air inlet pipe, compression is empty
Gas enters in sandbox die cavity from the passage of upper plate, and molten metal and iron sand are cooled down.After workpiece solidification, compressed air is closed,
Cavity turns into thermal resistance, hinders iron sand and outwards conducts heat so that workpiece cooling velocity slows down, and has reached control workpiece cooling velocity
Purpose.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment 1；
Fig. 2 is the structural representation of the utility model embodiment 2；
Wherein, 1- interior plates 2- upper plates 3- outer panels 4- air inlet pipe 5- upper plate 6- passage 7- cavitys 8- is filtered
Net 9- lower shoe 10- fasteners.
Embodiment
Embodiment 1：
Fig. 1 is welding sandbox, is welded after being combined by interior plate 1, upper plate 2, outer panel 3, upper plate 5 and lower shoe 9,
Cavity 7 is formd, air inlet pipe 4 is welded on outer panel 3, upper plate 5 is machined with passage 6, and passage 6 is dispersed throughout whole bottom
Plate.
Because iron sand granularity is smaller, and it is relatively difficult to process smaller than iron sand granularity passage, or processing charges are higher,
Generally, slightly larger passage is processed on upper plate, in use, one layer of covering or two layers of aperture are remote on upper plate 5
Less than the filter screen 8 of iron sand granularity, iron sand is avoided to be fallen into by passage 6 in cavity 7.
In use, the filter screen 8 for meeting upper plate size is layered on into sandbox bottom, shell mould is put into, is then gradually added into iron sand
Moulding, cast gate or rising head are finally installed, made after type etc. to be cast.
Pneumatics air valve is opened after casting complete immediately, pneumatics wind is blown into cavity 7 from air inlet pipe 4, then by passage 6
Sandbox die cavity is blown into, due to there is gap between iron sand, pneumatics wind is blown over from the gap between iron sand, heat is taken away, and is played cold
But the effect of workpiece and iron sand.Divulge information after certain time, close valve, the heat transfer of workpiece is to iron sand, and iron sand is again by heat
Pass to interior plate 1 and upper plate 5, because the outside of interior plate 1 and upper plate 5 is cavity, play thermal resistance effect, iron sand it is cold
But speed substantially slows down, so as to play slow cooling effect to workpiece.
Or air inlet pipe 4 is changed to exhaust tube and used, start vavuum pump, or opening and vacuum tube after casting complete immediately
The valve of road system connection, the gap that the air outside sandbox passes through between iron sand, enters cavity 7 from the passage 6 of upper plate 5
It is interior, then take the hot blast after cooling down iron sand away through air inlet pipe 4, it can also so play a part of cooling down workpiece and iron sand.
If desired improve cooling velocity, can or water cooling cold with mist be used cooperatively.After casting complete, iron sand shell mould sandbox is taken out
Gas, sandbox mouth sprinkling cooling water or atomized water, vacuum system can take the vapor after gasification away, accelerate the cold of iron sand and workpiece
But.
Embodiment 2：
Fig. 2 is the sandbox that cast steel or cast iron fastener connect, due to steel plate welding sandbox under thermal stress effect easily
It is deformed, it is impossible to long-term use of, the sandbox that the present embodiment is made using cast steel or cast iron.Especially form following mold box, i.e. sandbox
Inner chamber reached unanimity with casting outer shape, because sandbox is complex-shaped, especially interior chamber size, use casting technique system more
Make.
Air inlet pipe 4 can be together with sandbox casting, or uses threaded connection, or welding.
Compared with Example 1, casing is connected with lower shoe using fastener, using seal approach.
Other moulding and cooling means are same as Example 1.
The utility model iron sand shell mould sandbox can quickly be cooled down by air-cooled to casting, and blowing-out can be realized slow
Cold, for high-abrasive material workpiece, rapid cooling can obtain satisfied grain size and performance during solidification, after solidification slow cooling improve production
Product qualification rate.
