Description
Technical field
The present invention relates to the construction method that a kind of casting symmetrical above and below saves wooden model.
Background technology
At present, when casting symmetrical castings, it is necessary to a wooden model as cast shape first be manufactured, for manufacturing sand mold
Mould is used, when casting structure is complex, and manufacture wooden model needs to expend very big manpower and materials, and casts different casting
When, it is required for remanufacturing wooden model and sand mold mould, causes the consuming of timber larger.
The content of the invention
In view of this, it is an object of the invention to provide the construction method that a kind of casting symmetrical above and below saves wooden model, Neng Gou great
Consumptive material during big reduction manufacture wooden model, simplifies wooden model manufacturing process.
The present invention is realized using following scheme：A kind of casting symmetrical above and below saves the construction method of wooden model, according to the following steps
Carry out：（1）The manufacture wooden model consistent with double of shape of casting；（2）Wooden model is placed on, and lays on bottom plate position
Drag box in wooden model periphery；（3）Molding sand is poured into drag box and unnecessary molding sand is scraped off after being compacted；（4）Above and below drag box
Upset；（5）Wooden model is taken out, the lower sand mold consistent with wooden model shape is just molded in the molding sand of drag box；（6）In lower sand mold
Reinforcing bar is set up at opening, reinforcing bar is concordant with the molding sand upper surface in drag box；（7）Wooden model is placed on reinforcing bar, and wooden model
Downside edge matches with lower sand mold opening edge edge；（8）Cope is installed on drag box, and pours on cope molding sand
And scrape off unnecessary molding sand after being compacted；（9）Cope is opened, wooden model and reinforcing bar is taken out, molded in the molding sand of cope and wood
The consistent upper sand mold of mould shape；（10）Sandbox is closed again, the pouring molten iron into sand mold；（11）After natural cooling, casting is taken out.
Further, step（8）In, it is necessary to be sprinkled with parting in the molding sand upper surface of drag box before cope is installed
Sand, and blow off the tap sand for being sprinkled upon wooden model surface.
Further, step（2）And step（7）In, when placing wooden model, the wooden model one side corresponding with the casting plane of symmetry
Down.
Further, step（10）In, when taking out reinforcing bar, fill and lead up what is formed when reinforcing bar is set up on lower sand mold opening edge edge
Indent.
Further, step（8）In, need first to lay gate stick before molding sand is poured into, gate stick lower end needs contact
Wooden model upper surface.
Compared with prior art, the invention has the advantages that：Present invention casting symmetrical above and below saves applying for wooden model
Work method is used just can produce the sand mold as whole cast shape with double of equiform wooden model of casting, save significantly
Wooden model material is saved, while also simplify wooden model manufacturing process.
For the objects, technical solutions and advantages of the present invention are more clearly understood, specific embodiment and phase will be passed through below
Accompanying drawing is closed, the present invention is described in further detail.

Embodiment
As shown in Fig. 1 ~ 5, a kind of casting symmetrical above and below saves the construction method of wooden model, carries out according to the following steps：（1）Manufacture
The wooden model 2 consistent with double of shape of casting 1；（2）Wooden model 2 is placed on bottom plate 3, and laid on bottom plate 3 positioned at wooden model 2
The drag box 4 of periphery；（3）Molding sand is poured into drag box 4 and unnecessary molding sand is scraped off after being compacted；（4）Drag box is turned over about 4
Turn；（5）Wooden model 2 is taken out, the lower sand mold 8 consistent with wooden model shape is just molded in the molding sand of drag box 4；（6）In lower sand mold
Opening at set up reinforcing bar 5, reinforcing bar 5 is concordant with the molding sand upper surface in drag box 4；（7）Wooden model 2 is placed on reinforcing bar 5, and
And wooden model downside edge matches with lower sand mold opening edge edge；（8）Cope 6 is installed on drag box 4, and on cope
Pour into molding sand and scrape off unnecessary molding sand after being compacted；（9）Cope 6 is opened, wooden model 2 and reinforcing bar 5 are taken out, in the molding sand of cope
Mold the upper sand mold 9 consistent with wooden model shape；（10）Sandbox 6 is set up again, the pouring molten iron into sand mold；（11）Natural cooling
Afterwards, casting is taken out.
The present invention is when casting symmetrical castings, it is only necessary to which using one piece, half-and-half equiform wooden model just can be made with casting
Produce the sand mold as whole cast shape（It is made up of upper and lower sand mold）, wooden model material is saved, while also simplify wooden model
Manufacturing process.
In the present embodiment, step（8）In, it is necessary to be spilt in the molding sand upper surface of drag box 4 before cope 6 is installed
Upper tap sand, and blow off the tap sand for being sprinkled upon the surface of wooden model 2.
In the present embodiment, step（2）And step（7）In, when placing wooden model 2, wooden model 2 is relative with the plane of symmetry of casting 1
One answered is face-down.
In the present embodiment, step（10）In, when taking out reinforcing bar 5, fill and lead up when reinforcing bar 5 is set up on lower sand mold opening edge edge
The indent of formation, to prevent cast casting from producing unnecessary burr after finishing；Indent can not also be filled and led up, but is needed after casting is taken out
Remove the burr that molten iron enters indent and produced.
In the present embodiment, step（8）In, need first to lay gate stick 7 before molding sand is poured into, the lower end of gate stick 7 is needed
Contact the upper surface of wooden model 2；Gate stick is extracted after sand compaction in cope and just forms cast gate.
In the present embodiment, step（8）In, insertion one is also needed to before molding sand is poured into can form the thin of passage
Bar, is easy to the air in duration of pouring sand mold to discharge.
The object, technical solutions and advantages of the present invention are further described by above-listed preferred embodiment, are answered
Understand, the foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God is with principle, and any modification, equivalent substitution and improvements made etc. should be included in the scope of the protection.
