The utility model relates to the technical field of blow molding, in particular to an extrusion blow molding hollow molding machine, comprising a base, mounting mechanisms are symmetrically arranged above the base near the left and right sides, the mounting mechanisms comprise molding molds, mounting rods are fixedly connected to the outer surfaces of the molding molds, limit plates are welded and fixed to one ends of the mounting rods, sliding plates are arranged on the inner surfaces of the limit plates, the mounting rods are slidably connected with the inner walls of sliding grooves formed at the top ends of the sliding plates, the sliding plates are slidably connected with the inner walls of the sliding grooves corresponding to the positions of the sliding plates, insertion blocks are fixedly connected to the outer surfaces of the sliding plates, and the insertion blocks are in insertion fit with the inner walls of insertion slots corresponding to the positions of the insertion blocks. The extrusion blow molding hollow molding machine can conveniently replace molding molds with different hollow cavity shapes according to different shapes of production workpieces by arranging the mounting mechanisms. By arranging limit grooves, sliding grooves and insertion slots on the mounting base, users can conveniently limit the positions of the molding molds through the limit rods, the sliding plates and the insertion blocks.
