The invention discloses a blow molding machine and a hollow molding process, belonging to the technical field of polymer material blow molding, characterized in that it comprises a frame, an extruder, a mold closing mechanism and an air blowing mechanism for product molding, characterized in that the air blowing mechanism comprises one molding air blowing needle station and at least two shaping air blowing needle stations arranged at equal intervals. The beneficial effects of the invention are: greatly reducing the single cooling time, realizing flow operation in cooperation with the mold moving structure including a mold moving oil cylinder, a mold moving linear slide rail and a mold closing station, greatly reducing the processing time and improving the working efficiency; a plurality of mold closing stations are arranged on the mold moving oil cylinder connected to the mold moving linear slide rail, realizing the movement of the mold, and avoiding the problem that the preformed product is not truly cooled and shaped, and the transfer will inevitably lead to product damage.
