Document Type and Number:
WIPO Patent Application WO/2015/033693
Kind Code:
A1
Abstract:
Provided are a die casting method and a die casting device that can prevent a melt from unexpectedly being supplied to a sleeve under reduced pressure. Melt supply control (S100) for drawing a melt (M) by an electromagnetic pump (60) in a state of reduced pressure within a cavity (11) of a mold (10) and a sleeve (20) attached to the mold (10) and supplying the same to the sleeve (20) comprises a step for pulling back a molten surface of the melt (M) in a direction opposite to a supply direction for the melt (M) from a reference position (P0) by the electromagnetic pump (60), a step for reducing the pressure inside the cavity (11) and the sleeve (20), and a step for supplying the melt (M) to the sleeve (20) while weakening the pull-back force for the electromagnetic pump (60) in the direction opposite to the supply direction for the melt (M).
