Abstract: There are provided a method for manufacturing a core product, a method for removing a residual resin, and device for removing a residual resin including: supplying a molten resin; placing a conveying jig on a collection unit by conveying the conveying jig from a resin supply device to the collection unit together with a core body; splitting the resin solidified in a resin forming region from the resin solidified inside a resin flow path by removing the core body from the conveying jig; forming the residual resin which is a residue of the solidified resin inside the resin flow path and acquiring the core product including the core body and solidified resin formed in the resin forming region; and dropping the residual resin from the resin flow path into the collection unit by causing an extrusion unit to abut against the residual resin from above.

Abstract: The manufacturing method of a motor core includes attaching an ID code to a stack of blanked members in which a magnet insertion hole to fill with a resin material is formed, the ID code containing information in accordance with a type of the stack, reading the information from the ID code which is attached to the stack, and setting a mold condition based on the information read from the ID code. The mold condition includes at least one type of condition including: the resin material to be injected to the magnet insertion hole, an injection amount of the resin material, and a discharge position of the resin material. A mold device is controlled to inject the resin material to the magnet insertion hole in accordance with the mold condition.
