Abstract
The invention relates to the field of binders and in particular relates to a graphite powder loam core binder. The graphite powder loam core binder is characterized by comprising the following ingredients by weight percent: 50% of graphite powder, 20% of silica sol, 20% of fire clay and 10% of water. The graphite powder loam core binder has the advantages that once the graphite powder loam core binder is used for binding a mould component and casting a product, fashes at a loam core binding part can be effectively reduced, and a product runner is easy to clean and smooth, and as a result, the quality of casting equipment is greatly improved and manpower is saved.
Description
Technical field
The present invention relates to adhesive field, be specifically related to a kind of graphite powder loam core adhesive.
Background technology
Casting mould refers in order to obtain the model of qualified parts, common hand moulding, and wooden mold commonly used, plastic pattern, the multiplex metal pattern of machine moulding, as: aluminium pattern, swage type.Hot investment casting wax pattern, evaporative pattern polystyrene model.Casting mould refers in order to obtain the planform of part, with the material of other easy moulding, make in advance the planform of part, and then in sand mold, put into mould, so in sand mold, just formed a cavity the same with the design of part size, cast mobility liquid in this cavity again, this liquid cools just can form after solidifying and the duplicate part of mold shape structure.Casting mould be by the Driven by Hydraulic Cylinder injection plunger by molten metal high speed press-in die die cavity, because being uses oil pressure, pressure is higher, therefore be commonly called as casting mould technique.
In producing the sand mold mould process, some complicated structures, and mould is little, bad integral production, need split production, then together bonding by adhesive, originally use a kind of high product adhesive (organic matter is made), after mould was used, residue can be left in bonding place, the cleaning difficulty is large, and equipment quality descends.
Summary of the invention
In order to address the above problem, the present invention proposes a kind of graphite powder loam core adhesive, can effectively reduce the fash of bonding place between mould, the cleaning of product runner is smooth.
In order to reach the foregoing invention purpose, the present invention proposes following technical scheme:
Graphite powder loam core adhesive, is characterized in that the composition weight ratio of described graphite powder loam core adhesive is graphite powder 50%, Ludox 20%, fire clay 20%, water 10%.
Described graphite powder loam core adhesive is by raw material is proportionally stirred, and is mixed to form.
Advantage of the present invention is to use graphite powder loam core adhesives mold component, after cast article, can effectively reduce the fash of bonding place, loam core, and the easy cleaning of product runner is smooth, has greatly improved the quality of Casting Equipment, has saved manpower.
The specific embodiment
The production technology of graphite powder loam core adhesive is at first to choose raw material graphite powder, Ludox, fire clay and water, according to part by weight 5:2:2:1, then mixes, and then stirs.
During use, by graphite loam core adhesive, sand mold mould widget and the sand mold mould main body of casting are bonded together, during the sand mold mould Casting Equipment, after pouring molten iron into, sand mold mould and graphite powder loam core adhesive can run into molten iron and fall with regard to loose, and the product runner can be easy to clear up smooth like this.
Claims (2)
