Abstract
A kind of casting and molding method, is related to casting technology field, including melting, sand treatment, coremaking, moulding and cleaning process；Sand treatment gained molding sand is specifically carried out into coremaking, technique first and obtains core and mould；Next to that carrying out moulding using the molten iron obtained by melting, coremaking gained core and mould, cast article is obtained；It is exactly again to clear up, it is characterised in that：The molding sand that described casting and molding method is used is renewable sand, and practical old sand is returned into sand processing technique after moulding is processed；Scrap iron material and waste casting obtained by described cleaning technology return to smelting technology carries out melting, and reuses.Molding sand of the present invention can be reused, and production efficiency is high, can realize recycling for scrap iron and waste casting, save founding materials, reduce production cost.
Description
Technical field
The present invention relates to casting technology field, specifically a kind of casting and molding method.
Background technology
Casting technique is the technology and method for producing casting about theoretical and systematic knowledge using casting.Including Modeling Material preparation, moulding, coremaking, Metal Melting, cast and solidification control etc..Sand casting is a kind of using sand as main Modeling Material, makes the conventional casting techniques of casting mold.The adaptability of sand casting is very wide, smallclothes, big part, simple part, Complex Parts, and single-piece, high-volume can all be used.In the prior art, sand casting also has some shortcomings part：Because each chiltern casting mold can only be poured into a mould once, casting mold is to damage after obtaining casting, it is necessary to repeat style, so the production efficiency of sand casting is relatively low.Scrap iron and waste casting can be produced in moulding in addition, can not realize quickly effectively collecting and reusing in the prior art, cause the cost of waste of material, casting to raise.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of molding sand to reuse, and can consolidate saving material, reduce the casting and molding method of casting cost.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of casting and molding method, including melting, sand treatment, coremaking, moulding and cleaning process；Sand treatment gained molding sand is specifically carried out into coremaking, technique first and obtains core and mould；Next to that carrying out moulding using the molten iron obtained by melting, coremaking gained core and mould, cast article is obtained；It is exactly again to clear up, it is characterised in that：The molding sand that described casting and molding method is used is renewable sand, and practical old sand is returned into sand processing technique after moulding is processed；Scrap iron material and waste casting obtained by described cleaning technology return to smelting technology carries out melting, and reuses.
Scrap iron material and waste casting that the raw material that described smelting technology is used is reclaimed by the pig iron, steel scrap, alloy and cleaning technology.
The beneficial effects of the invention are as follows：Molding sand of the present invention can be reused, and production efficiency is high, can realize recycling for scrap iron and waste casting, save founding materials, reduce production cost.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the present invention is realized are easy to understand, with reference to specific embodiment, the present invention is expanded on further.
A kind of casting and molding method, including melting, sand treatment, coremaking, moulding and cleaning process；Sand treatment gained molding sand is specifically carried out into coremaking, technique first and obtains core and mould；Next to that carrying out moulding using the molten iron obtained by melting, coremaking gained core and mould, cast article is obtained；It is exactly again to clear up, the molding sand that casting and molding method is used is renewable sand, practical old sand is returned into sand processing technique after moulding is processed；Scrap iron material and waste casting obtained by cleaning technology return to smelting technology carries out melting, and reuses.Scrap iron material and waste casting that the raw material that smelting technology is used is reclaimed by the pig iron, steel scrap, alloy and cleaning technology.
General principle of the invention and principal character and advantages of the present invention has been shown and described above.It should be understood by those skilled in the art that; the present invention is not limited to the above embodiments; merely illustrating the principles of the invention described in above-described embodiment and specification; without departing from the spirit and scope of the present invention; various changes and modifications of the present invention are possible, and these changes and improvements all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by appending claims and its equivalent thereof.
