A plastic injection blow molding machine for bottles comprises a bed, an electrical control box, a hopper, an injection unit, a parison injection mold, a middle toggle plate, a rear toggle plate and a rear platen. It is characterized in that the locking mechanism of the parison injection mold changes the traditional longitudinal mold locking design into transverse mold locking, and the middle toggle plate drives the core rod to rotate 180° reciprocally for two-station injection-blow molding processing. A plastic injection blow molding machine for bottles can be formed only by adding a middle toggle plate and a transverse mold locking mechanism to the existing plastic injection molding machine. It has low investment and quick effect, and achieves the purpose of one machine for dual purposes.
