Summary: | The invention provides a method for preparing a mould pressing inductor of a high-compactness core column, which comprises the following steps of: preparing a mould pressing mould, and arranging a powder adding hole and a powder ejecting column in a cavity of a lower mould base; winding or sleeving the coil on the core column; the upper mold base drives the upper mold plate to descend, so that the coil enters the mold cavity; after the coil is separated, the upper template ascends to leave the lower die holder; inductance powder is distributed into the cavity; the upper mold base drives the upper mold plate to descend to press the powder in the mold cavity; meanwhile, the powder ejecting column ascends to eject powder in the powder increasing hole into the coil; and therefore, inductor pressing is completed. After the scheme is adopted, the cost of the coil can be saved, the size of the inductor can be smaller, and the compactness is higher.
