摘要： A die casting machine melt leakage detecting device includes a pulling wire, multiple wire winding columns, a wire fixing member, an elastic wire connecting member and a trigger switch. The pulling wire is capable of withstanding temperature outside a mold during normal die casting and is melted and broken after making contact with molten metal. The multiple wire winding columns are arranged around the mold, an end of the pulling wire is connected with the wire fixing member, and another end of the pulling wire is sequentially wound around the wire winding columns and is connected with the elastic wire connecting member. The elastic wire connecting member is opposite to the trigger switch, the elastic wire connecting member is in a compressed or stretched state when the pulling wire is kept tensioned in the operating state.
