The invention belongs to aluminium alloy casting fields, and in particular to a kind of composite casting core aluminium alloy Rapid casting process method.After the completion of casting sand type and sand core three-dimensional G- Design, according to the design feature and performance requirement at each position of casting, sand mold (core) is subjected to block design, corresponding Modeling Material and formative technology are selected according to mechanical property requirements, sand core prepared by various different materials and technique finally is combined integral sand mold (core) pours into a mould again.The present invention is for the requirement of each portion structure feature of aluminum alloy junction component and different ontology mechanical properties, the mode for being resorted to casting mold carries out Foundry Production, it can realize the quick preparation of casting, and obtain the high-quality casting that internal soundness, size and performance are met the requirements.
Description
Technical field
The invention belongs to aluminium alloy casting fields, and in particular to a kind of composite casting core aluminium for aluminium alloy sand mould casting closes
Golden Rapid casting process method.
Background technology
Aluminium alloy sand mould casting traditional at present is divided into resin sand casting and clay-bonded sand casting, and resin sand is divided into as furans tree
Fat, phenolic resin and phenol urethane resin, during traditional castings production, casting mold or casting core using a kind of fixed Modeling Material,
Aluminum chill or steel chill progress Quench is used to ensure that the ontology of casting is strong for position of the casting section thickness more than more than 15mm
Degree, and the position of certain structures complex (is there is boss etc. in type face on hyperboloid or face), chill difficult arrangement is directed to, easily
Because the shape that is not inconsistent of casting and chill leads to the dimension overproof of casting, and obtain poor surface quality.
Resin sand is only capable of for the higher casting of certain bulk properties by increasing chill ruler since its heat-transfer capability is limited
It is very little to improve bulk strength, but since running gate system position can not place chill, cause to set position and the placement of running gate system
The position bulk properties of chill differ greatly, and difference is generated to casting overall performance.
Invention content
The present invention be directed to the requirement of each portion structure feature of aluminum alloy junction component and ontology mechanical property, in the sand of casting
When type designs, corresponding Modeling Material and process is taken each position to carry out the preparation of sand core or sand mold, and finally combine
It is poured into a mould again into the casting mold (core) needed for cast casting, so as to obtain the height that internal soundness, size and performance are met the requirements
Quality casting.Specific technical solution is as follows：
A kind of composite casting core aluminium alloy Rapid casting process method, includes the following steps：
The first step, blank drawing draw, by design size drawing size and requirement drafting Casting Three-dimensional figure, and draw casting mold and
Cast core entirety graphics；
Second step, casting mold core block design,
Casting mold and casting core graphics are carried out piecemeal to sand core according to the requirement of each portion structure feature and mechanical property to set
Meter：
1) to big plane or the external surface position without boss, bead structures use wooden model or metal mould forming；
2) it is more than 15mm, the complicated position with rib or boss for casting local thickness, using machine plus stone
Black type is processed into graphite core；
3) for carrying the big position of hyperboloid structure, mold input cost using 3D printing sand core straight forming；
4) position for reserving chill in advance is taken for the position that arrangement chill is needed on 3D printing sand core, size is less than
The chill of 100mm takes machine that graphite chilling block or steel chill is added to carry out the chill of damascene process, size more than 100mm, using iron ore
Sand fills re-entrant portion after being mixed with resin；
Third walks, and corresponding Modeling Material and formative technology are selected according to mechanical property requirements,
Prepared by the 4th step, casting mold core, will design the casting mold completed and casting core is processed preparation according to manufacturing process；
Each casting mold and casting core are molded, form the cavity needed for casting by the 5th step, molding；
6th step, is poured into a mould according to casting technique；
7th step, casting are molded, and after casting complete, casting mold and casting core are taken out to obtain corresponding casting.
Beneficial effects of the present invention
The present invention is resorted to for the requirement of each portion structure feature of aluminum alloy junction component and different ontology mechanical properties
The mode of casting mold carries out Foundry Production, can realize the quick preparation of casting, and obtains internal soundness, size and performance satisfaction and want
The high-quality casting asked.
