Abstract

PURPOSE:To obtain a high-strength hollow member integrally and simultaneously formed with longitudinal and lateral ribs by a method wherein a lip die of specified constitution is fitted to the outflow side opening end portion of a material mold, and cores are advanced and retracted between the interior of the lip die and that of the metal die. CONSTITUTION:A lip die 2 having an opening portion rectangular in cross section is fitted to the outflow-side opening portion of a metal mold 1. With cores 3 positioned in the lip die 2, raw material A in plasticized state is fed into a pressure chamber 9. Then, there is formed a hollow plate 13 which is rectangular in cross section and hollow portions 12 partitioned, e.g., into three, the partition walls serving as longitudinal ribs 14. After extrusion forming is continued under such condition for a while, the cores 3 are retracted into the chamber 9 as far as air hole forming pins 10 are located in the lip die 2. Under this condition, the raw material A is pressure fed and extruded through the lip die 2 to form a lateral rib 15. Then, cores 3 are advanced, and longitudinal ribs 14 are formed in the same has way as above. USE:Structural material.
