Abstract
The invention discloses a molding sand for casting. The molding sand is characterized in that it is composed of the following raw materials by weight: 30 parts of tempered molding sand, 60 parts of resin, 10 parts of attapulgite clay, 4 parts of talcum powder, 2 parts of bentonite and 3 parts of gypsum powder, as well as a proper amount of water. When the materials are stirred uniformly, the molding sand for casting can be obtained. The molding sand for casting provided in the invention has the advantages of simple preparation method, reasonable formula, as well as low cost, and can be widely applied to the casting field.
Description
Technical field
The present invention relates to a kind of casting field, a kind of specifically moulding sand for casting.
Background technology
Sand mold generally adopts gravitational casting, also can adopt technologies such as low pressure casting, centrifugal casting when specific (special) requirements is arranged.The adaptability of sand casting is very wide, smallclothes, big part, and simple part, complicated part, all can adopt in enormous quantities single-piece.The mould that sand casting is used, many in the past with the timber making, the common name wooden model.The wooden model shortcoming is yielding, fragile; Except that the sand-cast of single-piece production, can use dimensional accuracy higher, and service life is than long aluminum alloy mould or resin die.Though price increases, but still the mould considerably cheaper of using than permanent mold casting, in small lot and big part were produced, price advantage was particularly outstanding.In addition, sand mold is higher than metal mold refractoriness, thereby the material also many employings this technology higher like fusing points such as copper alloy and ferrous metal.But sand casting also has the some shortcomings part: because each chiltern casting mold can only be poured into a mould once, casting mold promptly damages behind the acquisition foundry goods, and moulding again is so the production efficiency of sand casting is lower; The porous because the bulk property of sand is soft again, so the casting dimension accuracy of sand casting is lower, the surface is also more coarse, the direct influence quality of casting out product of the quality of molding sand in casting process.
Summary of the invention
Deficiency and defective in order to alleviate prior art the object of the present invention is to provide a kind of moulding sand for casting.
The present invention adopts following technical scheme to achieve these goals:
A kind of moulding sand for casting is characterized in that the weight portion of its constitutive material is: return molding sand 30-40 part, resin 60-85 part, attapulgite 10-15 part, talcum powder 4-8 part, bentonite 2-5 part and land plaster 3-6 part, water is an amount of; Above material get final product after through even stirring moulding sand for casting.
Beneficial effect of the present invention:
Preparation method of the present invention is simple, fill a prescription reasonable, with low cost, can apply to casting field widely.
The specific embodiment
Embodiment 1: a kind of moulding sand for casting is characterized in that the weight portion of its constitutive material is: return molding sand 30-40 part, resin 60-85 part, attapulgite 10-15 part, talcum powder 4-8 part, bentonite 2-5 part and land plaster 3-6 part, water is an amount of; Above material get final product after through even stirring moulding sand for casting.
Embodiment 2: a kind of moulding sand for casting is characterized in that the weight portion of its constitutive material is: return 3 parts of 30 parts in molding sand, 60 parts of resins, 10 parts of attapulgites, 4 parts of talcum powder, 2 parts of bentonites and land plasters, water is an amount of; Above material get final product after through even stirring moulding sand for casting.
