Abstract
The utility model discloses a kind of nut casting sand mold, comprise sand mold and lower sand mold, upper sand mold is provided with the first half of flange die cavity, and the first half of flange die cavity is connected with body die cavity; Lower sand mold is provided with the latter half of flange die cavity, the latter half of flange die cavity is connected with ingate, ingate is opening up hemisphere hull shape, and ingate thickness is less than body die cavity thickness, and is all connected along inner side with on ingate inside the surrounding of flange die cavity lower end.The beneficial effect of this programme can be learnt according to describing of such scheme, structure is simple, reasonable in design, ingate changes present hemisphere shell mould cast gate into by original two cylinder cast gates, both made ingate area increase, again because the contact thickness of itself and foundry goods reduces, thus also reduce ingate and foundry goods contact thermal center, the cold shut of foundry goods, Shrinkage cavity are reduced, and casting quality is greatly improved.
Description
Technical field
The utility model relates to a kind of casting sand type, particularly relates to a kind of nut casting sand mold.
Background technology
Before, as shown in Figure 1, what nut casting sand mold adopted is the ingate of cast-type at the bottom of two, if find in production process that ingate area is too small, just easily occurs cast(ing) surface misrun phenomenon or produces cold shut defects; If ingate area is bigger than normal, then can produce new thermal center at ingate and foundry goods contact position, this thermal center modulus is greater than the modulus of foundry goods itself, makes foundry goods and ingate contact position easily produce shrinkage cavity defect, and the yield rate of foundry goods reduces.
Utility model content
The utility model is for the deficiency existing for prior art, and it is simple, reasonable in design to provide a kind of structure, both made ingate area increase, what turn reduce ingate and foundry goods contacts thermal center, makes the nut casting sand mold that the cold shut of foundry goods, Shrinkage cavity reduce.
To achieve these goals, the utility model provides a kind of nut casting sand mold, comprise body die cavity and the flange die cavity of described nut, comprise sand mold and lower sand mold, described upper sand mold is provided with the first half of described flange die cavity, the first half of described flange die cavity is connected with described body die cavity, and described body die cavity is connected with two along the equally distributed rising head of described body die cavity; Described lower sand mold is provided with the latter half of described flange die cavity, and the latter half of described flange die cavity is connected with ingate, and described ingate is connected with runner gate, and described runner gate is connected with down gate; Described ingate is opening up hemisphere hull shape, and it is all connected with described flange die cavity along surrounding.
Wherein, described ingate thickness is less than described body die cavity thickness, and described flange die cavity lower end inside is connected along inner side with on described ingate.
Described ingate is positioned at above described runner gate.
Described rising head is open riser.
This programme nut casting sand mold forming process is as follows:
1, sand mould box, lower sand mould box in the smooth placement of difference;
2, in upper sand mould box, place top box mould, place rising head and down gate in the corresponding position of top box mould, in lower sand mould box, place nowel mould, put runner gate and ingate in nowel mould corresponding positions.
3, in upper sand mould box, lower sand mould box, molding sand is put into and consolidation respectively.Steam vent is pricked again on upper sand mould box.
4, after sand solidified, lift takes out top box mould and nowel mould.
5, die cavity is repaired.
6, remove the coating its surface brush two to three times after the floating sand in die cavity, and make its surfacing.Without concave and convex phenomenon.
7, mould assembling is to be cast.
The beneficial effect of this programme can be learnt according to describing of such scheme, structure is simple, reasonable in design, after improving, pouring position is constant, but ingate changes present hemisphere shell mould cast gate into by original two cylinder cast gates, has both made ingate area increase, again because the contact thickness of itself and foundry goods reduces, thus also reduce ingate and foundry goods contact thermal center, the cold shut of foundry goods, Shrinkage cavity are reduced, and casting quality is greatly improved.
Accompanying drawing explanation
Fig. 1 is the structural representation before nut casting sand mold;
Fig. 2 is the structural representation of the utility model detailed description of the invention;
In figure, 1, body die cavity; 2, flange die cavity; 3, upper sand mold; 4, lower sand mold; 5, open riser; 6, ingate; 7, runner gate; 8, down gate.
Detailed description of the invention
For the technical characterstic of this programme can be clearly demonstrated, below by detailed description of the invention, this programme is set forth.
As shown in Figure 2, the utility model is a kind of nut casting sand mold, comprise body die cavity 1 and the flange die cavity 2 of nut, comprise sand mold 3 and lower sand mold 4, upper sand mold 3 is provided with the first half of flange die cavity 2, the first half of flange die cavity 2 is connected with body die cavity 1, and body die cavity 1 is connected with two along the equally distributed open riser 5 of body die cavity 1; Lower sand mold 4 is provided with the latter half of flange die cavity 2, the latter half of flange die cavity 2 is connected with ingate 6, ingate 6 is opening up hemisphere hull shape, and ingate 6 thickness is less than body die cavity 1 thickness, and all with on ingate 6 is connected along inner side inside the surrounding of flange die cavity 2 lower end; Ingate 6 is connected with runner gate 7, and ingate 6 is positioned at above runner gate 7, and runner gate 7 is connected with down gate 8.
This programme nut casting sand mold forming process is as follows:
1, sand mould box, lower sand mould box in the smooth placement of difference;
2, in upper sand mould box, place top box mould, place rising head and down gate in the corresponding position of top box mould, in lower sand mould box, place nowel mould, put runner gate and ingate in nowel mould corresponding positions.
3, in upper sand mould box, lower sand mould box, molding sand is put into and consolidation respectively.Steam vent is pricked again on upper sand mould box.
4, after sand solidified, lift takes out top box mould and nowel mould.
5, die cavity is repaired.
6, remove the coating its surface brush two to three times after the floating sand in die cavity, and make its surfacing.Without concave and convex phenomenon.
7, mould assembling is to be cast.
The utility model can pass through without the technical characteristic described or adopt existing techniques in realizing; do not repeat them here; certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned citing; the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
