  • Publication number: 20120058214
    Abstract: A multiple press molding machine may include a plurality of guide shafts and a plurality of die units. Each of the die units includes a pair of dies, a plurality of guide holes and a plurality of bushes each having a through bore. Each of the bushes is positioned so as to surround at least one open peripheries of each of the guide holes. The guide shafts are respectively inserted into the guide holes of the die units and the through bores of the bushes, so that die closing and opening motion can be guided. The through bore of each of the bushes has an inner diameter smaller than a diameter of each of the guide holes.

  • Patent number: 7992927
    Abstract: A reinforcing brace excellent in productivity and cost performance is provided which can advantageously improve a rigidity of a floor panel without deteriorating aerodynamic performance. The reinforcing brace comprising a longitudinal press-formed product including a cylindrical section 12 located at a middle area in a longitudinal direction thereof and flat portions 44, 44 located at end areas in the longitudinal direction thereof. Further, an outer surface of the cylindrical section 12 is made as regulating surfaces 26, 32, 36 which reduce air resistance by regulating a flow of air passing under the vehicle body. Furthermore, a plurality of insertion holes 46 are positioned in the flat portions 44, 44 into which fastener members are inserted.

  • Patent number: 7144244
    Abstract: A molding machine (1) may include first and second dies (13, 23) arranged and constructed to be closed and opened, and first and second trimming members (17, 27) arranged and constructed to engage with each other after the first and second dies are closed. When the first and second dies (13, 23) are closed, a resin based sheet material (S?) is pressed so as to form a molded material (S). When the first and second trimming members (17, 27) engage with each other, the molded material (S) is circumferentially trimmed so as to produce a molded article (Sa) and a waste strip (Sb).
