Claims

[Scope of utility model registration request]

A blow magazine is filled with shell sand supplied from a hopper, and pressurized air is used to blow the shell sand in the blow magazine into a core mold to form a core of a cast part. The magazine includes a blow magazine body filled with shell sand, a blow nozzle for blowing sand into the core mold, and a removable blow plate that covers the opening of the blow magazine body. Then, in the blow magazine body between the opening of the blow magazine body and the blow plate,
A blow magazine for a shell machine for forming a core of a cast part, characterized in that a baffle plate is attached to allow shell sand to pass through during sand blowing with pressurized air, but to suppress natural falling of the shell sand.
