[0009] As optimization, the telescopic end of the motor-driven push rod is embedded in the embedding groove, and the outer diameter of the top plate is consistent with the inner diameter of the embedding groove.

[0010] The present application has the following beneficial effects:

[0011] The dry-pressing forming mold for ceramic bodies drives the connecting rod to reciprocatingly push and pull the knocking rod through the rotation of the crank, and then drives the knocking rod to reciprocatingly enter and exit the fixed cylinder, so that the knocking head is reciprocatingly knocked against the side wall of the movable chamber, the surface of the dry-pressed body is separated from the inner wall of the mold, and the top plate is driven to rise upward through the start of the motor-driven push rod, so that the dry-pressed body is conveniently taken out upward.
