The invention discloses a glass bottle die casting piece manufacturing process cyclically using molding sand. According to the invention, a manufactured glass bottle die casting piece has an accurate size and no subcutaneous blowholes; sand discharging of castings is convenient after molding, used sand can be regenerated and reused and has a low breakage rate and small loss in the process of regeneration of the used sand, and the reuse rate of the used sand is high; the process produces little dust, little pollution and no phenol and formaldehyde.

Description

The Glass tube mould foundry goods manufacturing process that molding sand can be recycled
Technical field
The present invention relates to the Glass tube mould foundry goods manufacturing process that molding sand can be recycled.
Background technology
The material of Glass tube mould is alloy cast iron, the about 30kg of the general substance of foundry goods, four, a type.In the manufacture process of Glass tube mould foundry goods, will use sand mold, Glass tube mould foundry goods has clay sand, resin sand and water-glass sand with the conventional molding sand of sand mold at present.Adopt clay sand, after cast, the swollen sand of foundry goods is serious, not only wastes molten iron, and has increased follow-up amount of machining.Adopt resin sand, can discharge that excitant is poisonous, pernicious gas when cast, can produce pollution, and after cast, foundry goods there will be a large amount of subcutaneous blowholes, percent defective raises.Adopt water-glass sand, the foundry goods difficulty of shaking out after cast, old sand can not regeneration, causes the sand wasting of resources.
Summary of the invention
The Glass tube mould foundry goods manufacturing process that the object of the present invention is to provide a kind of molding sand can be recycled, the Glass tube mould casting dimension of its manufacture is accurate, without subcutaneous blowhole defect, and after cast, foundry goods shakes out conveniently, the renewable reuse of old sand, and the breakage rate of regenerating used process medium sand is little, loss is few, and reclaimed sand reclamation rate is high.And this technique dust is few, pollute less, there is no phenol, formaldehyde.
For achieving the above object, technical scheme of the present invention is the Glass tube mould foundry goods manufacturing process that a kind of molding sand of design can be recycled, and comprises the steps:
1) mulling: drop into molding sand and composite inorganic adhesive carries out mulling in puddle mixer; The input amount of described composite inorganic adhesive is the 3.5%-4.5% of molding sand quality; Described molding sand is made up of the fresh sand of 0-15% and the reclaimed sand of 85%-100%;
2) moulding: open plain jolter, the molding sand mixing is dropped into ram-jolt in the sandbox that casting mould is housed, venting, passes into carbon dioxide and make sand mold sclerosis, makes Glass tube mould foundry goods sand mold; Wherein, the pressure carbon dioxide passing into is 0.12-0.2MPa;
3) pour into a mould and solidify; Pouring molten iron after sand mold mould assembling, makes Glass tube mould foundry goods after solidifying;
4) vibrating shakeout: sand mold is come off from Glass tube mould foundry goods;
5) breaking, regenerating: make sand mold vibrations broken, make reclaimed sand;
6) seethe with excitement cooling: reclaimed sand is seethed with excitement cooling, is aided with dust removal of pneumatic separation;
7) cooled reclaimed sand is dropped into step 1) middle continuation use.
Preferably, the main component of described composite inorganic adhesive is potassium oxide, sodium oxide molybdena, lithium metasilicate, silica, aluminium oxide, starch ether and water.
Preferably, described composite inorganic adhesive is provided by Shenzhen Jing Ding modern science and technology Co., Ltd, and described composite inorganic adhesive is made up of the component of following percentage by weight: aluminium oxide, the starch ether of 0.5%-1.5% and the water of surplus of the lithium metasilicate of the potassium oxide of 4%-6%, the sodium oxide molybdena of 9%-11%, 14%-16%, the silica of 9%-11%, 4%-6%.
Preferably, described composite inorganic adhesive is made up of the component of following percentage by weight: 5% potassium oxide, 10% sodium oxide molybdena, 15% lithium metasilicate, 10% silica, 5% aluminium oxide, 1% starch ether and the water of surplus.
Preferably, in vibrating shakeout, fragmentation, mulling step, carry out dust removal of pneumatic separation.
Preferably, described puddle mixer is continuous muller.
The moulding of this process using sand lump, mold thickness is little, can save Modeling Material cost.
Because sand mold is shaped to the rear molding of molding sand sclerosis, gained die cavity clear-cut, the dimensional accuracy of foundry goods is high.And sand mold has higher intensity and impact resistance, when cast, sand mold does not need auxiliary casing, saves workload and cost.
The gas forming amount of this manufacturing process is low, has overcome the foundry goods subcutaneous blowhole defect of phenolic sand molding.
Sand mold collapsibility in technique of the present invention is good, easily shakes out conveniently from the Glass tube mould foundry goods foundry goods that comes off, and reduces cleaning work amount.
Old sand after cast shakes broken after vibrating shakeout, magnetic separation, by phase mutual friction at high speed between sand and sand, the residual binding agent of part is peeled off from sand grains, then sand grains enters vibration boiling cooler, further peel off and stay adhensive membrane, and be aided with dust removal of pneumatic separation, and make to remove in time from adhensive membrane and the dust of old sand sur-face peeling, can obtain the reclaimed sand of energy reuse.
The breakage rate of technique regenerating used process medium sand of the present invention is little, and loss is few, reclaimed sand reclamation rate high (reclamation rate > 90%), sand using amount significantly reduces, and reclamation of return sand employing dry back use, does not need heating, save sand resource, reduced energy consumption.
In addition, this technique dust is few, pollutes less, there is no phenol, formaldehyde, can improve the pollution of other molding sand process to environment.
Accompanying drawing explanation
Fig. 1 is process chart of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described.Following examples are only for technical scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.
