ABSTRACT:
Molding apparatus and method for producing die castings having high, closely spaced projections extending therefrom formed by mold portions which are re-entrant or interleaved between the projections of the casting. Such re-entrant mold portions do not cool rapidly between casting shots and their tips are liable to stick to the casting, making it difficult or impossible to release. The invention provides a die mold having such re-entrant portions and a method of rapidly cooling such portions between casting shots in order to provide acceptable production rates.
