In the above-mentioned assembly structure using the key lock cavity, the bonding and fixing of the hardened sand and the end core formed in the reverse slope key lock cavity portion provided in the end core are insufficient. Due to the impact during transportation / installation, a gap is created between the adjacent case cores and a gap is created, and a casting cast using this creates a failure because accuracy cannot be maintained. What is described in the above-mentioned JP-A-1-133638,
Since the channels or openings of the plurality of cores are open to the outside, in order to fill the mixture of sand and solidifying agent by the second blow machine, it is necessary to install it in a mold or a mold equivalent covering the part. Further, the above-mentioned Japanese Patent Laid-Open No. 5-185181
The method disclosed in Japanese Patent Publication requires a process such as sealing before and after the adhesive is injected into the adhesive injection hole penetrating a plurality of sand mold groups.
