Equipment and method for manufacturing rotor core

A rotor core manufacturing method wherein magnets are inserted into magnet housing holes formed in a core body and a resin is supplied into the holes to fill the magnet housing holes housing the magnets and subsequently cured therein to fix the magnets to the core body, the method comprising:

• arranging the core body with the magnets housed in the magnet housing holes on a stationary mold, arranging a movable mold with a resin flow passage on the core body, and arranging a cull plate between the core body and the movable mold, the cull plate comprising a filling pot that guides the resin flowing out through the resin flow passage to the magnet housing holes and holds a cull as the cured resin after the curing;
• filling the magnet housing holes with the resin supplied via the filling pot through the resin flow passage and curing the resin filled in the magnet housing holes;
• and
• separating the cull from the core body by removing the movable mold and subsequently detaching the cull plate from the core body,
• wherein the filling pot of the cull plate comprises an inlet which is opposite an outlet of the resin flow passage, and
• wherein the inlet of the filling pot has an area greater than the outlet of the resin flow passage.
