Abstract
The utility model discloses a kind of lost foam casting vacuum sand box, it forms bottom pumping type sandbox system by original vavuum pump and bottom pumping type sandbox, aspirating chamber drilling dividing plate in side is welded on bottom pumping type inner wall of sand box along bottom pumping type sandbox bottom and top surrounding, form side aspirating chamber and composition Integral air chamber is connected with sandbox bottom air plenum, stainless steel seat type filter screen then is fixed on into side aspirating chamber with interior hexagonal trip bolt by filter screen drilling fixed plate drills on dividing plate.The lost foam casting vacuum sand box has the characteristics of simple in construction, low manufacture cost, safe and reliable, can improve each position negative pressure distributional difference in sandbox, eliminates resulting various casting flaws.
Description
Technical field
It the utility model is related to casting sandbox, and in particular to a kind of lost foam casting vacuum sand box.
Background technology
Evaporative pattern belongs to dry sand cavityless casting, and it is viscous to be different from traditional green-sand casting, not aqueous, bentonite, coal dust etc.
Agent composition is tied, buries case moulding dry sand ram-jolt filling fixed model.Evaporative pattern production cast when, it is necessary to by sandbox vacuumize come
Sand bond is improved, prevents from after crush and cast rising case during cast.The sandbox generally used at present is by vavuum pump and bottom pumping type
The pure bottom pumping type vacuum sand box system of sandbox composition, find that each position negative pressure difference is larger in sandbox after the sandbox use, performance
It is more serious especially for being influenceed when producing tall and big part to successively decrease from sandbox bottom close to vavuum pump up and to surrounding, hold
The defects of easily causing the case that rises, crush.
The content of the invention
It is true that the purpose of this utility model is to provide a kind of low manufacture cost, simple to operate, safe and reliable lost foam casting
Empty sandbox, to improve each position negative pressure distributional difference in sandbox, eliminate resulting various casting flaws.
To achieve the above object, a kind of lost foam casting vacuum sand box of the utility model include vavuum pump, bottom pumping type sandbox,
Side aspirating chamber drilling dividing plate, stainless steel seat type filter screen, filter screen fixed plate with holes and interior hexagonal trip bolt；The vavuum pump with
Bottom pumping type sandbox forms bottom pumping type sandbox system；The side aspirating chamber drilling dividing plate is welded on the inwall surrounding of bottom pumping type sandbox,
Side aspirating chamber is set to connect composition Integral air chamber with sandbox bottom air plenum；The stainless steel seat type filter screen is fixed by filter screen with holes
Plate is fixed on the aspirating chamber drilling dividing plate of side with interior hexagonal trip bolt.
The lost foam casting vacuum sand box of said structure, will original pure bottom pumping type vacuum sand box system by increasing side aspirating chamber
System is transformed into bottom and takes out plus side odd test vacuum sand box system, improves each position negative pressure distributional difference in sandbox, eliminates and thus produce
Raw various casting flaws, there is the characteristics of simple in construction, low manufacture cost, safe and reliable.
Brief description of the drawings
Fig. 1 is that the utility model pure bottom pumping type vacuum sand box system reform is taken out plus side odd test vacuum sand box system architecture the bottom of into and shown
It is intended to.
Reference：It is vavuum pump 1, bottom pumping type sandbox 2, side aspirating chamber drilling dividing plate 3, stainless steel seat type filter screen 4, with holes
Filter screen fixed plate 5, interior hexagonal trip bolt 6.
Embodiment
It is true that plus side odd test is taken out the bottom of into the pure bottom pumping type vacuum sand box system reform with reference to the accompanying drawings and detailed description
Empty sandbox system is described in further detail.
A kind of lost foam casting vacuum sand box of the utility model shown in Fig. 1 includes vavuum pump 1, bottom pumping type sandbox 2, side pumping
Room drilling dividing plate 3, stainless steel seat type filter screen 4, filter screen fixed plate 5 with holes and interior hexagonal trip bolt 6；The vavuum pump 1 with
Bottom pumping type sandbox 2 forms bottom pumping type sandbox system；The side aspirating chamber drilling dividing plate 3 is welded on the inwall four of bottom pumping type sandbox 2
In week, side aspirating chamber is set to connect composition Integral air chamber with sandbox bottom air plenum；The stainless steel seat type filter screen 4 passes through filter screen with holes
Fixed plate 5 is fixed on the aspirating chamber drilling dividing plate 3 of side with interior hexagonal trip bolt 6.Thus form bottom and take out plus side odd test vacuum sand
Case system, its job step order are as follows：
When the 1st, preparing cast, vacuum switch is opened, vacuum pump interface, which rises, compresses sandbox bottom air plenum interface, vavuum pump
Connected with sandbox bottom air plenum and side aspirating chamber；
2nd, during vacuum pump work, on molding sand, sandbox various places inside forms relatively stable uniform caused suction function
Negative pressure, the molding sand compact rate of molding in such sandbox everywhere is more consistent, molding sand firm fixing is lived the mould beam to be poured into a mould；
3rd, vavuum pump is closed afterwards for a period of time by technological requirement pressurize after casting complete, vacuum pump interface declines with departing from sand
Case bottom air plenum interface, mo(u)lding line operation promote next sandbox to prepare cast；
4th, above step is repeated, is vacuumized vacuum-assist pouring work next time.
By the way that the pure bottom pumping type vacuum sand box system reform is taken out into plus side odd test vacuum sand box system the bottom of into, can effectively solve
Certainly caused by pure bottom pumping type vacuum sand box system because negative pressure difference in sandbox and caused by rise case, crush etc. it is various casting lack
Fall into, so as to improve product qualification rate.
