Draw-back
A portion of mould, which owing to some peculiarity of form in the pattern, or because of some difficulty presented in closing or finishing the mould, must be slided back or lifted away altogether. When this occurs in moulds that are made entirely in flasks, some portion, or all of a cheek-part, is made to answer by attaching inside bars, or a connected bottom-plate to carry the sand. But, when the mould is all contained in the floor, a plate with lifting-handles is cast, on which to carry away the desired part. The plate is termed a drawback plate. See CHEEK; FALSE CORE.
