Abstract

THERE IS DISCLOSED AN IMPELLER (1) OF A CENTRIFUGAL BLOWER WHICH HAS A GOOD FLOW PERFORMANCE, AND CAN BE PRODUCED IN A RELATIVELY SHORT TIME AT LOW COSTS, AND HAS HIGH PRECISION OF BALANCE AND SO ON. THE IMPELLER (1)INCLUDES A BOSS (2) PROVIDED AT AN AXIS OF ROTATION OF THE IMPELLER (1), A PLURALITY OF BLADES (4) ARRANGED ON A CIRCLE, A SHROUD (5), AND A HUB (3) HAVING AN OUTER DIAMETER (DHI) LARGER THAN AN INNER DIAMETER (DS1) OF THE SHROUD (5).THE IMPELLER (1) IS MOLDED INTO AN INTEGRAL CONSTRUCTION BY A MOLD WHICH INCLUDES CORES (D1,D2,D3,D4,D5,D6) WHICH ARE PROVIDED IN A REGION CORRESPONDING TO A SPACE TO BE FORMED BY THE HUB (3), THE SHROUD (5) AND THE BLADES (4),AND EACH OF THE CORES (D1,D2,D3,D4,D5,D6) COMPRISES A LOWER CORE WITHDRAWABLE RADIALLY OUTWARDLY FROM THE MOLD, AND AN UPPER CORE WHICH IS PIVOTALLY MOVABLE ABOUT AN AXIS TO BE WITHDRAWN FROM SAID MOLD IN SUCH A MANNER THAT THE UPPER CORE WILL NOT INTERFERE WITH THE MOLDED HUB (3).(FIG. 1)
