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: 公开了一种用于从模具内形成的铸件移除模具的方法。 通过对模具刻痕并施加足以使模具破碎并破碎成碎片的力，可将模具从铸件上移除。 此外，模具可能因放置在模具包中的爆炸性炸药或通过指向模具的高能脉动而断裂。 一旦模具破裂并破碎成各种碎片，它就会从铸件上脱落下来。
