PROBLEM TO BE SOLVED: To provide a method of manufacturing a laminated iron core in which poor filling of a resin is less likely to occur, even for an iron core body having large volume of a magnet insertion hole.SOLUTION: In a method of manufacturing a laminated iron core, permanent magnets 14 are inserted, respectively, into magnet insertion holes 12, 13 of an iron core body 15 having the plurality of magnet insertion holes 12, 13, and then the magnet insertion holes 12, 13 are filled with a resin from a resin reservoir pot 30 while sandwiching the permanent magnets 14 by an upper die 17 and a lower die 18, thereby securing the permanent magnets 14. The magnet insertion holes 12, 13 are filled with a resin from the resin reservoir pot 30 via a common runner 31 and gate holes 33, 34, and a cull plate 16 is removed after the permanent magnets 14 is secured.SELECTED DRAWING: Figure 1 |
