A kind of environmental protection casting system
Technical field
The utility model relates generally to casting field, is specifically related to a kind of environmental protection casting system.
Background technology
Casting system is exactly in sand mold, to guide liquid metal to enter the passage of die cavity, reasonably casting system design, should be according to the design feature of foundry goods, technical conditions, alloy species, select casting system structure type, determine and introduce position, calculating sectional dimension, because the Modeling Material that sand casting is used is cheap and easy to get, Casting mold manufacturing is easy, single-piece production to foundry goods, produces by batch and produces and all can adapt in a large number, for a long time, be the basic technology in Foundry Production always.Sand casting casting mold used is generally combined by outer sand mold and core, and in order to improve the surface quality of foundry goods, be everlasting sand mold and whose surfaces are brushed a coating, and the main component of coating is pulverulent material and the binding agent that refractoriness is high, chemical stability is good.
After foundry goods moulding, need foundry goods to take out cleaning, casting cleaning comprises: remove surperficial scab, inner residual core, remove the operations such as running gate system and joint flash, these amount of operation labor are large and environment is severe, especially in the process of casting cleaning, can produce the nuisances such as a large amount of dusty gas and dust, make working environment become very severe.
Summary of the invention
For the existing problem of steel casting in prior art, a kind of environmental protection casting system that the utility model provides, can realize producing fast in a large number of foundry goods, and reduce the pollution of environment, improves workman's work situation.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of environmental protection casting system, mainly comprise modelling chamber, model integration chamber, mould assembling casting room, sand removal chamber, rear portion, described modelling chamber is provided with model integration chamber successively, mould assembling casting room, sand removal chamber, in casting process, first adopt molding sand to make after sand mold mould in modelling chamber through compacting, be made into model by foundry goods, enter subsequently model integration chamber, upper/lower die is integrated together, then enter next mould assembling casting room, liquid metal is poured in mould and is tentatively shaped, wait for after casting solidification, foundry goods and molding sand are transported in sand removal chamber by slideway, the indoor vibratory sieve that is provided with of described sand removal, described vibratory sieve provides power by the bobbing machine connecting, and foundry goods is screened, and makes molding sand fall into below, sand removal chamber, and foundry goods is stayed the collection of vibratory sieve top and is transported, top, described sand removal chamber is provided with collection conduit, when vibratory sieve screens foundry goods, can produce the nuisances such as a large amount of dusty gas and dust, collection conduit by top, sand removal chamber is taken dusty gas to unify to process away, and casting sand is by re-using after the unified collection and treatment in vibratory sieve below.
Preferably, the slideway top of described sand removal chamber is provided with atomizer, through atomizer spray water, has reduced the generation of dust.
The beneficial effects of the utility model show: the bonding of molding sand has tentatively been cleared up in described sand removal chamber by vibratory sieve, work personnel's workload has obtained minimizing, foundry goods passes through the sprinkling of atomizer by slideway, reduce the generation of dust, in vibratory sieve work, by the collection conduit at top, sand removal chamber, flue dust is all taken away, work situation is greatly improved simultaneously.

1-modelling chamber, 2-model integration chamber, 3-mould assembling casting room, 4-atomizer, 5-sand removal chamber, 6-bobbing machine, 7-vibratory sieve, 8-collection conduit in figure.
Detailed description of the invention
For the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing, the utility model is further described.
A kind of environmental protection casting system as shown in Figure 1, mainly comprise modelling chamber 1, model integration chamber 2, mould assembling casting room 3, sand removal chamber 4,1 rear portion, described modelling chamber is provided with model integration chamber 2, mould assembling casting room 3, sand removal chamber 5 successively, mould assembling casting room 3 connects sand removal chamber 5 by slideway, slideway top is provided with atomizer 4, in described sand removal chamber 5, be provided with vibratory sieve 7, described vibratory sieve 7 is connected with bobbing machine 6; Vibratory sieve 7 in described sand removal chamber 5 provides power by the bobbing machine 6 connecting, foundry goods is screened, make molding sand fall into 5 belows, sand removal chamber, foundry goods is stayed vibratory sieve 7 tops collections and is transported, 5 tops, described sand removal chamber are provided with collection conduit 8, when vibratory sieve 7 screens foundry goods, can produce the nuisances such as a large amount of dusty gas and dust, collection conduit 8 by 5 tops, sand removal chamber is taken dusty gas to unify to process away.
When casting: first adopt molding sand to make after sand mold mould in modelling chamber 1 through compacting, be made into model by foundry goods, enter subsequently model integration chamber 2, upper/lower die is integrated together, then enter next mould assembling casting room 3, liquid metal is poured in mould and is tentatively shaped, foundry goods and molding sand are transported in sand removal chamber 5 by slideway, slideway reduces by atomizer 4 flue dust that foundry goods produces in slip, when vibratory sieve 7 screens foundry goods, can produce the nuisances such as a large amount of dusty gas and dust, collection conduit 8 by 5 tops, sand removal chamber is taken dusty gas to unify to process away, casting sand is unified to re-use after collection and treatment by vibratory sieve 7 belows.
Above content is only to structure example of the present utility model and explanation; affiliated those skilled in the art make various amendments to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the structure of utility model or surmount this scope as defined in the claims, all should belong to protection domain of the present utility model.
