Abstract
A forming device and a preparation method of a graphite crucible are provided. The forming device includes: a support frame, including a base; a male die, disposed on the support frame and far away from the base and movable reciprocally in a vertical direction relative to the support frame; a crucible mouth pressing member, disposed on the support frame, correspondingly disposed on a side of the male die close to the base, movable reciprocally in the vertical direction relative to the support frame, and defining an opening part allowing the male die to pass therethrough; and a female die, disposed on the base and corresponding to the male die, and configured to accommodate crucible paste. The male die, the crucible mouth pressing member and the female die are configured to cooperatively form the crucible paste into the graphite crucible.
