The utility model relates to the technical field of plastic production, and discloses a blow molding device for hollow plastic products, which comprises a blow molding machine body. Sliding grooves are formed on the front and rear sides of the bottom end of the blow molding machine body, lower slide rails are movably installed inside the sliding grooves, the number of the lower slide rails is two, and bottom covers are fixedly installed at the bottom ends of the two lower slide rails. In the blow molding device for hollow plastic products, sliding grooves are formed at the bottom end of the blow molding machine body, lower slide rails are installed inside the sliding grooves, two sets of bottom covers are arranged at the bottom ends of the lower slide rails, fixing grooves are formed inside the top cover and threaded rods are movably sleeved. When the bottom covers need to be opened, the turntable can be rotated to drive the threaded rods to rotate; since the thread directions at both ends of the threaded rods are opposite, the two sets of bottom covers can be driven to move away from or towards each other, realizing stable opening and closing, thus achieving the advantage of convenient and stable opening of the bottom covers.
