The disadvantages of traditional modulazation design for large-scale vertical centrifugal casting were analyzed. A new design method was introduced. Multi-step round-cavity groove position was adopted in designing chassis of centrifugal machine. The combination mould design of general backing plate
general cover plate and special metal sleeve was conduced with the design of general serial flower-shaped plate and bolt locking
which improved greatly the re-utilization rate of backing plate
cover plate and coordinate locking mechanism
decreased comprehensive cost of mould by 40% and shortened greatly the production period.
