MECHANISM FOR PREVENTING CORE COMPONENT FROM FLOATING

摘要

PROBLEM TO BE SOLVED: To solve the problem that there are dimensional difficulties in adopting such conventional methods and complication in constituents for core components in case of a small-diameter core component subject to a geometrically strict limitation and that the flow channel area of coolant is narrow and the inlet flow speed of a relevant core component exceeds an allowable value too much because integral molding should be conducted by building a latch spring in an entrance nozzle for the small-diameter core component subject to a geometrically strict limitation in mechanisms using conventional technologies to prevent core components from floating. SOLUTION: The mechanism for preventing the core components from floating conforms even to the small-diameter core components subject to a geometrically strict limitation, eliminates the necessity of the latch spring for the floating prevention mechanism and is allowed to have the latch spring function by forming a slit on the entrance nozzle in itself to unite the structure of the mechanism.
