という利点がある。[Effects of the Invention] As explained above, the method for manufacturing a laminated core and the manufacturing mold according to the present invention are such that two or more types of core pieces having different plate thicknesses, shapes, or materials are driven into a die portion in a predetermined order. After the core pieces are punched out and laminated and integrated, they are taken out from the die, so instead of conventionally making each core piece in a separate mold and then combining them into one piece, the core pieces are punched out in the same die. (2) Conventionally, it was necessary to manage parts for each core piece, but since it can be manufactured within the die, product management is easier. and (3) post-treatment such as annealing is possible after assembly as a product, so the feel of the entire laminated core will not deteriorate.
