Abstract

PURPOSE:To obtain a hollow product with pretty-looking external finish free from air blow hole, etc. at low cost by suction action of a vacuum air port created inside a metal mold's forming chamber and residual air pressure inside parison all in one forming action. CONSTITUTION:Half-molten tube-shaped parison 3 squeezed out from head 2 of die 1 of extruding machine is held between split molds 4A, 4B of forming metal mold 4. Vaccum action is caused to take place on plural vacuum air orifices 6 provided on the inner surface of forming chamber 5. Parison is formed into a hollow product along the wall of forming chamber 5 by vacuum's suction action and residual air pressure inside parison 3.
