摘要： A body frame for a motor bicycle includes a main frame, a head tube provided at a front end of the main frame and down tubes extending rearward from the main frame. The main frame, head tube and down tubes are cast with a light alloy into an integral form of a hollow and thin-wall structure. A production process of the body frame, wherein an integrally-formed core, which is formed into a shape similar to that of the body frame, is hollow and has good permability. A molten metal is charged into the mold and a vacuum is applied to the interior of the core. The molten metal is charged into a cavity defined between the core and the molding surface of the mold by a low-pressure casting method, and the molten metal is solidified so as to cast the body frame. A production apparatus of the body frame includes a liftable cope fitted to a vertical casting machine, a fixed drag, and slidable molds disposed in combination with the cope and being capable of horizontally sliding in a state that the cope is released from the drag. A body frame having both properties of light weight and high stiffness, and a production process and apparatus thereof is provided wherein casting defects and to provide a high-precision cast article, is provided.

摘要： A method of, and an apparatus for extruding a billet of a light metal alloy, wherein the billet has an outer diameter smaller than a maximum configuration width and larger than a minimum configuration width of the die hole at its entry side. The billet is pressurized and extruded by a stem to form a preshaped portion which is larger than the entry side configuration of the die hole, at a frontal end portion of the billet near an entry portion of the die hole. The preshaped portion of the billet is subsequently shaped by the die hole into an extruded shape corresponding to the cross-sectional shape of the die hole and of parts formed from the extruded billet, e.g., of an automobile suspension arm. A reduced resistance and a minimized extrusion pressure upon extrusion of a light metal alloy result from the preshaping of the billet and enable realization of a compact and less expensive arrangement of the production facility.

摘要： A method of and an apparatus for extruding a billet of a light metal alloy, wherein the billet has an outer diameter smaller than a maximum configuration width of the die 2 at its entry side. The billet is pressurized and extruded by a stem 5 to form a preshaped portion via die 2 which is greater than the entry side configuraton of the die 1 at a frontal end portion of the billet near an entry portion of the die hole. The billet is subsequently shaped by the die 1 into an extruded shape corresponding to the cross-sectional shape, e.g. of an automobile suspension arm. A reduced resistance and a minimized extrusion pressure upon extrusion of a light metal alloy enable realization of a compact and less expensive arrangement of the production facility.
