ることを特徴とする乾式等方圧加圧成形装置。 It consists of an injection unit A that injects the kneaded material 1, and a molding unit B that presses and molds the material 1 supplied and filled from the injection unit A under isostatic pressure, and the injection unit A has an injection nozzle 9 at its tip. A kneading screw shaft 5 is inserted into an injection cylinder 4 having a heat source 3 in its barrel so as to be rotatable around its axis and movable in the axial direction. An injection drive body 6 for applying injection pressure and injection speed is provided at the end, and a check valve portion 5A for freely opening and closing the nozzle hole 9A of the injection nozzle 9 is provided at the tip of the kneading screw shaft 5. On the other hand, the molding unit B has a pressurized rubber mold 20 and a molded rubber mold 21 in a pressure vessel 11 whose axial ends are closed by an upper lid 13 and a lower lid 17 and which has a pressure medium supply port 19. The upper lid 13 side has a connection port 22 communicating with the molding chamber 21A in the molding rubber mold 21, and the lower lid 17 side has molded product removal means 15, 16. , further comprising injection unit drive bodies 8, 8a, and 23 that move the injection unit A so that the injection nozzle 9 can be freely connected to and separated from the connection port 22. Device.
