The invention discloses a blow molding machine and a hollow molding process, belonging to the technical field of polymer material blow molding. The blow molding machine comprises a frame, an extruder, a mold clamping mechanism for product molding, and an air blowing mechanism, wherein the air blowing mechanism comprises one molding blow pin station and at least two shaping blow pin stations arranged at equal intervals. The beneficial effects of the invention are: single cooling time is greatly reduced; with a mold moving structure including a mold moving cylinder, a mold moving linear slide rail, and mold clamping stations, assembly-line operation is realized, processing time is greatly shortened, and work efficiency is improved. Multiple mold clamping stations are arranged on mold moving cylinders connected to the mold moving linear slide rail, realizing mold movement and avoiding damage to preforms caused by transfer before complete cooling and shaping.
