Preparing mould for casting disc-shaped body, partic. brake disc

摘要

The mould cast (1) comprises two halves (1a,1b) and is divided in a division plane (X-X). In each of the two mould box halves, the pattern of the disc mould body to be produced is moulded after the introduction of mould sand (5) in the mould box halves with the formation of a corresponding cast hollow space cavity. The hollow spaces, formed in the cast body, are closed by cores set in the mould box. In the mould box (1) are an outer core and an inner core (3). After bringing the mould halves together, the hollow space of the mould is formed and is filled with metal smelt, esp. cast iron, for prodn. of the disc mould body (4). The pattern is moulded only with an inner core.
