Abstract
The utility model discloses a novel valve investment composite shell mold and is used for solving the problems of poor connection between a water glass layer and a silica sol layer of an existing composite shell mold and low product accuracy. The novel valve investment composite shell mold sequentially comprises a silica sol emery powder coating layer, a first water glass mullite powder coating layer, a mullite powder coating layer, a second water glass mullite powder coating layer and a slurry sealing layer from the inner wall to the outer wall, wherein composite sand layers are respectively arranged between the silica sol emery powder coating layer and the first water glass mullite powder coating layer and between the first water glass mullite powder coating layer and the mullite powder coating layer; mullite sand layers are respectively arranged between the mullite powder coating layer and the second water glass mullite powder coating layer and between the second water glass mullite powder coating layer and the slurry sealing layer. According to the novel valve investment composite shell mold, a silica gel shell-making process is adopted on an inner surface layer, and water glass shell-making processes are adopted on a reinforcing layer and a protection layer, so that the novel valve investment composite shell mold has the advantages of possessing the silica gel shell-making accuracy and greatly reducing the production cost.
Description
Technical field
The utility model relates to the compound shell mould of a kind of novel valve fusible pattern.
Background technology
Domestic market is for oil exploitation, chemical plant, nuclear power, the valvelet of the aspects such as thermoelectricity and military project, high ferro, aviation, the foundry goods consumption of space flight high-end product is increasing, often there are in process of production some small-bore valves (refer to 6 inches following valves) here as for oil field, natural gas is exploited resistance to hydrogen chloride and carbon dioxide material and for the valve of nuclear power and chemical enterprise highly corrosion resistant, this class valve not only requires more also to valve foundry goods inner clamps foreign material the performance of foundry goods and chemical analysis, air content and segregation require also very strict, to the apparent mass of foundry goods, require standard also very high.At present domestic also have some large enterprises to occur Ludox investment casting shell, but production cost is higher, and waterglass investment casting shell exists the problem of low precision.Composite shell model casting new method is the new method between waterglass investment casting shell technique and Ludox investment casting shell technique; its interior surface layers has adopted Improving Shell Making with Silica Sol; back-up coat and protective layer adopt waterglass process for making shell; existing silicon appearance glue-line is connected always poor with waterglass layer, can not meet the needs of production.
Summary of the invention
For solve in background technology existing compound shell mould at waterglass layer, be connected with silica sol layer junction poor, the problem that Product Precision is not high enough, the utility model provides a kind of novel valve fusible pattern compound shell mould.
The technical solution of the utility model is: the compound shell mould of a kind of novel valve fusible pattern comprises successively Ludox schmigel dope layer, the first waterglass mullite powder dope layer, mullite powder dope layer, the second waterglass mullite powder dope layer, slurry seal layer from inwall to outer wall; Between described Ludox schmigel dope layer and the first waterglass mullite powder dope layer, be equipped with compound layer of sand between the first waterglass mullite powder dope layer and mullite powder dope layer, between described mullite powder dope layer and the second waterglass mullite powder dope layer, be equipped with mullite layer of sand between the second waterglass mullite powder dope layer and slurry seal layer.
As a kind of improvement of the present utility model, described Ludox schmigel dope layer has two-layer, between described two-layer Ludox schmigel dope layer, is provided with quartz sand layer.
As further improvement of the utility model, described slurry seal layer adopts waterglass mullite powder slurry to solidify and forms.
The beneficial effects of the utility model are, interior surface layers has adopted Improving Shell Making with Silica Sol, and back-up coat and protective layer adopt waterglass process for making shell, make this product have the precision of silicon sol casing simultaneously, greatly reduce again the production cost of product.
