Intelligent core assembly system and process suitable for casting sand cores of engine cylinder blocks and cylinder heads

Abstract

The invention relates to an intelligent core assembly system and technology suitable for casting sand cores of engine cylinder blocks and cylinder heads, and belongs to the technical field of casting. This includes the core assembly system cylinder head cylinder outer mold core area, cylinder head inner cavity core, part of the cylinder inner cavity core core area and cylinder core core area, cylinder head cylinder outer mold core conveying line, Surface drying furnace conveyor line, surface drying furnace, vertical warehouse, vertical warehouse conveying line, core conveying line and robots with corresponding functions; all sand cores are manufactured by cold box core making unit, and the dimensional accuracy of castings is high; at the same time, the process of the present invention It is realized in a fully automated way, with robot transfer, glue coating, dip coating, marking, air hole drilling, core assembly, packing and core setting. The whole core assembly process realizes the combination of the total assembly of sand cores, improving the positioning accuracy of sand cores and The reliability of the connection improves the accuracy of the cylinder body from CT9 to CT8; this process has a high degree of intelligence, low labor intensity, high production efficiency, energy saving and consumption reduction, and is easy to popularize and apply.

Description

technical field [0001] The invention belongs to the technical field of casting, and in particular relates to an intelligent core assembly system and technology suitable for casting sand cores of engine cylinder blocks and cylinder heads. Background technique [0002] At present, the process characteristics of the core assembly core wire in the domestic foundry industry: (1) cylinder head and cylinder block are produced in separate lines, (2) hot melt adhesive is often used for sand core bonding; (3) sand core assembly Screws are manually threaded for fastening; (4) Casting numbers of castings are mostly generated in the core box using character codes. [0003] The above-mentioned core assembly process method has the following disadvantages: (1) The cylinder head and the cylinder body are produced in separate lines, and the flexibility of the production line is low. Two lines are required to produce the cylinder body and the cylinder head, and the investment in equipment is l...

Problems solved by technology

[0003] The above-mentioned core assembly process method has the following disadvantages: (1) The cylinder head and the cylinder body are produced in separate lines, and the flexibility of the production line is low. Two lines are required to produce the cylinder body and the cylinder head, and the investment in equipment is large; (2) Sand cores are used for bonding Hot melt adhesive is used for fastening, the curing time of hot melt adhesive is short, and the production adaptability is poor; (3) when the sand core is assembled, manual screw is used for fastening, and the production efficiency is low; (4) the casting number is formed when the sand core is made , it is necessary to change the character code frequently, which wastes time and reduces production efficiency
