Zusammenfassung:	PURPOSE:To obtain easily each upper deck on the top of each core by forming a jacketed die into the type provided with suitably spaced notches and cores existing deviately below the inside of the respective notches. CONSTITUTION:Plural pieces of suitably spaced notches 11 opening downward are disposed to a jacketed die 9 and spaces 12 are formed so as to exist on the upper side in the respective notches 11. Freely dischargeable cores 13 consisting of sand, etc. are set therein. If pressure casting is performed by using the die 9 of such type and the cores 13 are collapsed and discharged after the casting, internal passages 14 are obtd. and at the same time, upper decks 15 are integrally formed on the top. Higher rigidity is thus provided to jackets 2.
