Claims

[Scope of utility model registration request]

A core mold is fixed to each opposing surface of a pair of mold support frames that can be moved relatively close to each other, and a large number of gas supply ports are dotted on the back side of each core mold, corresponding to each core mold. In a casting core manufacturing apparatus equipped with burner plates arranged in a shape, a coupler is provided at each gas supply port, and each coupler is fixed to each gas supply port and a socket having an annular step integrally protruding from the inner peripheral surface of a gas passage communicating with the socket;
It consists of a cam locking mechanism that is biased by a spring and moves freely, and a burner nozzle or embolus that is removably locked in the socket via the cam locking mechanism and whose rear edge abuts the annular step. Casting core manufacturing equipment.
