Abstract: Disclosed is a method for dislodging a mold from a casting formed within the mold. The mold may be removed from the casting by scoring the mold and applying a force sufficient to cause the mold to fracture and break into pieces. Additionally, the mold may be fractured by either explosive charges placed in the mold pack or by high energy pulsations directed at the mold. Once the mold is fractured and broken into various pieces it may then be dislodged from the casting.

Abstract translation: 公开了一种从模具内形成的铸件中移出模具的方法。 可以通过对模具进行刻划并施加足以使模具断裂并分解成碎片的力来从模具中移除模具。 此外，模具可能通过放置在模具包装中的爆炸装置或通过指向模具的高能量脉动而断裂。 一旦模具断裂并破碎成各种碎片，它可能会从铸件中脱落。
