Abstract
Embodiments relate to automating removal of an untrimmed shell from a mold. In one embodiment, a shell removal device includes a body and a platform disposed within the body. The platform is configured to secure a mold that has an untrimmed shell formed over the mold. The shell removal device further includes a cover configured to secure the untrimmed shell to an upper surface of one or more sidewalls of the body and provide a seal between a lower surface of the untrimmed shell and the upper surface of the one or more sidewalls of the body. The shell removal device may include a media inlet in the body to permit pressurized media into the interior of the body to cause a pressure differential between an upper surface of the untrimmed shell and the lower surface of the untrimmed shell to cause the untrimmed shell to release from the mold.
