Abstract
The present invention relates to adhesive field, be specifically related to a kind of Graphite powder loam core binder.Graphite powder loam core binder, is characterized in that the composition weight ratio of described Graphite powder loam core binder is graphite powder 50%, Ludox 20%, fire clay 20%, water 10%.Advantage of the present invention uses Graphite powder loam core binder bonding mold component, after cast article, effectively can reduce the fash of bonding place, loam core, and product runner easily cleared up smooth, substantially increase the quality of Casting Equipment, save manpower.
Description
Technical field
The present invention relates to adhesive field, be specifically related to a kind of Graphite powder loam core binder.
Background technology
Casting mould refers to the model in order to obtain qualified parts, common hand moulding, conventional wooden mold, plastic pattern, the multiplex metal pattern of machine moulding, as: aluminium pattern, swage type.Hot investment casting wax pattern, evaporative pattern polystrene phantom.Casting mould refers to the planform in order to obtain part, the planform of part is made in advance with other easily shaping materials, and then mould is put in sand mold, so just define a cavity the same with design of part size in sand mold, pour into a mould mobility liquid in the cavity again, this liquid cools just to be formed after solidifying and the duplicate part of mold shape structure.Casting mould is by Driven by Hydraulic Cylinder injection plunger by molten metal high speed press-in die die cavity, and owing to being use oil pressure, pressure is higher, therefore is commonly called as casting mould technique.
In production sand mold mould process, some complicated structures, and mould is little, bad integral production, needs split production, then bond together by adhesive, originally a kind of high product adhesive (organic matter is made) of use, after mould uses, residue can be left in bonding place, cleaning difficulty is large, and equipment quality declines.
Summary of the invention
In order to solve the problem, the present invention proposes a kind of Graphite powder loam core binder, effectively can reduce the fash of bonding place between mould, the cleaning of product runner is smooth.
In order to reach foregoing invention object, the present invention proposes following technical scheme:
Graphite powder loam core binder, is characterized in that the composition weight ratio of described Graphite powder loam core binder is graphite powder 50%, Ludox 20%, fire clay 20%, water 10%.
Described Graphite powder loam core binder is by raw material is proportionally stirred, and is mixed to form.
Advantage of the present invention uses Graphite powder loam core binder bonding mold component, after cast article, effectively can reduce the fash of bonding place, loam core, and product runner easily cleared up smooth, substantially increase the quality of Casting Equipment, save manpower.
Detailed description of the invention
The production technology of Graphite powder loam core binder first chooses raw graphite powder, Ludox, fire clay and water, according to part by weight 5:2:2:1, then mixes, then stir.
During use, by graphite loam core binder, the sand mold mould widget of casting and sand mold mould main body are bonded together, during sand mold mould Casting Equipment, after pouring molten iron into, sand mold mould and Graphite powder loam core binder can run into molten iron just loose fall, it is smooth that such product runner can be easy to cleaning.
