Slag discharging structure of pressing bore of oil press

The utility model provides an oil press pressing bore deslagging structure which comprises a pressing chamber, a discharging control cylinder is detachably arranged at the discharging end of the pressing chamber, the discharging control cylinder is composed of an abutting ring and an embedding ring, an embedding groove matched with the outer diameter of the embedding ring is formed in the inner wall face of the discharging end of the pressing chamber, and the abutting ring is arranged in the embedding groove. The inner diameter of the embedded ring is smaller than that of the discharging end of the barrel, so that a step structure is formed at the joint of the embedded ring and the barrel, two opposite L-shaped grooves are formed in the inner wall face of the embedded groove, the corners of the two L-shaped grooves are distributed in the circumferential direction of the barrel, and locking blocks matched with the L-shaped grooves in width are arranged on the outer wall face of the embedded ring. The barrel an
