The invention relates to the field of manufacturing of plastic pipe materials, and aims to provide a moving device of a plastic corrugated pipe forming machine and the plastic corrugated pipe forming machine. The moving device of the plastic corrugated pipe forming machine comprises a plurality of half mold mounting seats, an annular guide rail provided with an outer guide groove and an inner guide groove, and a half mold mounting seat driving device; each of the half mold mounting seats comprises a seat body, two vertical shafts and two guide wheels, and the seat body is formed by a vertical plate and two end plates which are separately in one-to-one connection with the upper end and the lower end of the vertical plate; each of the vertical shafts is detachably connected with the corresponding end plate; each of the two guide wheels is in one-to-one connection with one end of the corresponding vertical shaft; a vacuumizing hole penetrating through the outer side end of the vertical plate is formed in the middle part of the inner side end of the vertical plate; and two positioning countersunks which are symmetrically arranged on the upper side and the lower side of the vacuumizing hole and two limiting blocks which are separately located on one side of the corresponding positioning countersunk are formed in the outer side end of the vertical plate. The parts and components of the moving device of the plastic corrugated pipe forming machine and the parts and components of another moving device which is arranged symmetrical with the moving device can be exchanged for common use.
