    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

    摘要: The present invention provides a method of manufacturing a pipe with a branch, which utilizes the conventional pipe molding method using a floating core, and while taking advantage of the pipe molding method, various types of pipes with a branch can be integrally molded with a synthetic resin with high efficiency. The method comprises injecting a molten resin into a main cavity 4, which has on its one end a pressure port 2 provided with a floating core 1 and on its other end a first outlet 3, and a branch cavity 5, which communicates with the main cavity 4 and has on its end a second outlet 6 allowed to open and close, pressure-injecting a pressurized fluid through the pressure port 2 after the injection of the molten resin, and moving the floating core 1 to the first outlet 3 side, and, at the same time, extruding the molten resin from the first outlet 3 to form a main pipe hollow, and opening the second outlet 6 after the main pipe hollow reaches a portion at which the branch cavity 5 communicates with the main cavity 4, and extruding the molten resin by the pressurized fluid from the second outlet 6 to form the branch pipe hollow.

    摘要: Abstract: Disclosed is a device for manufacturing resin molded articles for use in optical elements. Said device is provided with: a first mold, which is fixed in place; a second mold that has, on a cavity mold surface, a transfer surface for transferring an optical surface to a molten resin injected into the cavity; a nozzle for injecting a fluid under pressure into the molten resin injected into the cavity, thereby forming a void inside said molten resin; and an ejector pin that is provided in the second mold, protruding from the mold surface thereof, to release a base material from the mold surface. The nozzle is provided on a part of the cavity mold surface other than the transfer surface of the second mold and has a tip formed so as to protrude from the mold surface into the cavity. The ejector pin protrudes at a position between a position corresponding to the tip of the base material nozzle and the end of the aforementioned optical surface on the side on which the tip of the nozzle is disposed.
