ABSTRACT:
A casting mold assembly includes cope and drag sections having a casting cavity therebetween and a casting core supported within the cavity. A vertical down sprue extends through the cope section and joins a flow passage extending through the core in prolongation of the down sprue for introducing molten metal directly into the mold cavity to produce a disk brake rotor. A filter is supported in the flow path of the core and a flow control lip is provided at the exit of the flow path to provide a flow constricting gap between the annular lip and an underlying lower cavity wall to slow the flow of metal into the cavity.
