Plastic bottle forming equipment and plastic bottle blow molding method

The invention discloses plastic bottle forming equipment and a plastic bottle blow molding method. The plastic bottle forming equipment comprises two mold assemblies which can be spliced with each other; the mold assembly comprises a shell, a cavity is formed in the shell, a model column is arranged in the cavity, a driving device is arranged on the shell, the driving device can drive the model column to rotate in the shell with the axis of the model column as the axis, one side of the model column is concaved inwards to form a plastic bottle blow molding cavity, and the plastic bottle blow molding cavity is communicated with the cavity. The other side of the heating tube is recessed inwards to form a heating cavity, and a heating lamp tube is arranged in the heating cavity. The plastic bottle blow molding system solves the problems that a bottle blank heating system and a blow molding system of an existing plastic bottle blow molding system are separately carried out, the temperature of a heated bottle blank
