An opening and closing mold device with adjustable parallelism relates to the technical field of hollow blow molding machines, including mold plates, pull arm connecting flanges, pull arms, mold frame fixed seats, tie rods, tie rod fixed seats, oil cylinders, mold frames and mold frame moving seats. Two mold plates are symmetrically arranged and fixed on the mold frames by screws. One mold frame is fixed on the mold frame fixed seat, and the other is mounted on the mold frame moving seat. The fixed seat and moving seat are respectively connected to pull arms via connecting flanges. Tie rod fixed seats are screwed on the pull arms, with both ends of tie rods fixed inside the seats. Oil cylinders are installed on the pull arms and drivingly connected to the mold frame moving seat. The device greatly reduces mechanical processing difficulty without restriction from mold frame size, and allows adjustment of pull arm angles according to product length and contour.
