The foundry production line designed and manufactured by Zhejiang mechanical and electrical design and Research Institute Co., Ltd. is mainly developed for the production of large castings such as marine engine crankshaft, truck axle housing, engine cylinder block, etc., which promotes the development of the priority area of the application of sand-clad foundry. The main features are large size and weight of the iron mold, good rigidity of the production line equipment and high degree of mechanization.
So, what are the main problems solved in the process design of sand-clad iron mold casting
① the thickness of the wall and sand layer of the sand-clad casting of the iron mold and the combination of the two, so as to meet the different requirements of different wall thickness and different material castings for solidification and cooling;
② convenient and economical sand covering molding method to meet the requirements of different castings for surface quality and dimensional accuracy;
③ process parameters. Such as the determination of pouring system, sand shooting system, exhaust system, etc;
The realization of mass production. For example, the design and finalization of the production line and the main and auxiliary machines covered with sand;
⑤ formulation of process procedures, such as pouring, cooling and unpacking procedures, as well as adjustment of casting composition, etc.
