摘要： The present invention provides a hollow body molding device which allows easy confirmation of passage of a floating core through a molded body and facilitates quality control at the site. In a hollow body molding device in which a molten resin is injected into a main cavity 1, a pressurized fluid is pressure-injected through a pressure port 3 after the injection of the molten resin, a floating core 2 is moved to the outlet side, the molten resin is extruded from the outlet simultaneously with the movement of the floating core 2, and a hollow molded body 12 is molded, the hollow body molding device is provided with a floating core storage portion 6 which is connected to the main cavity 1 and stores the floating core 2 moved by the pressurized fluid, an auxiliary cavity 10 which stores a molten resin discharged from the main cavity 1 and the floating core storage portion 6, communication passages 7 and 9 which communicate the floating core storage portion 6 and the auxiliary cavity 10 with each other; and an opening and closing means 8 that opens and closes the communication passages 7 and 9 by sliding movement. In the hollow body molding device, each inlet cross-sectional area B of the communication passages 7 and 9 is B
