Patent number: 4889177Abstract: The invention relates to a method and apparatus for sand molding composite articles formed of a light alloy metal and fibrous insert. A sand mold is formed containing a fibrous preform separated from the walls of the mold cavity. The mold is fed by means of a tube dipping into a liquid metallic bath therebelow. In the molding process, the pressure in the mold cavity and above the bath are reduced, and the pressure above the bath is increased to create a positive pressure differential .DELTA.P, thereby forcing molten metal from the bath into the mold cavity. The pressure in the mold cavity and above the bath are then increased to above atmospheric, and the pressure differential .DELTA.P is maintained until the metal in the mold cavity solidifies.Type: GrantFiled: June 7, 1988Date of Patent: December 26, 1989Assignee: Cegedur Societe de Transformation de L'Aluminium PechineyInventors: Jean Charbonnier, Francois Goliard

Patent number: 4886106Abstract: A die casting apparatus for forming rotors for electric motors. The apparatus includes a frame having at least two opposed stationary pressure plates and a rotating turret rotatively mounted betewen these stationary plates. The turret includes three apertures at three equally spaced locations around the turret. Tooling is arranged at each of the respective locations for forming a rotor. Compensating and casting tooling is located at a first station, pin pressing and trimming tooling is located at the second station and unloading and loading tooling is located at the third station. The operations at the respective stations proceed simultaneously. The operations are selected so that the combined operations of each of the stations will take approximately equal amounts of time.Type: GrantFiled: March 15, 1988Date of Patent: December 12, 1989Assignee: HPM CorporationInventor: Charles H. Bennett

Patent number: 4774993Abstract: A device, configured as a double mold, for casting terminal bars (straps) and terminal poles onto the lugs of a completely assembled plate group for electric storage batteries ensures optimum attachment of all of the lugs (both polarities) to the molten bar lead if the heat exchange between the bar lead and the dipped volume of each negative or positive lug is identical. This requirement is met by causing the negative and positive casting molds, together with their contents, to form thermally equivalent sections or blocks, which are equalized if necessary, by changing the dimensions (thickness) of the mold's walls. When the lugs are made of lead or a lead alloy, such a double mold also makes it possible, during a subsequent two-stage cooling process, to first allow the terminal poles to solidify, simultaneously, and to then allow the terminal bars to solidify, simultaneously.Type: GrantFiled: May 19, 1987Date of Patent: October 4, 1988Assignee: Varta Batterie AktiengesellschaftInventors: Bernhard Kallup, Wolfgang Glittenberg, Christian Kubis, Gerolf Richter, Christian Ressel

Method and apparatus for manufacturing composite material using pressure chamber and casting chamber
Patent number: 4572270Abstract: A composite material is manufactured from a formed mass of reinforcing material and matrix metal by introducing the reinforcing material mass into a pressure chamber and holding it there, introducing molten matrix metal into the pressure chamber so as to surround the reinforcing material mass, moving the reinforcing material mass from the pressure chamber into a casting chamber of substantially smaller volume than the pressure chamber while it is still being surrounded by molten matrix metal, and then allowing the molten matrix metal to solidify while applying pressure.Type: GrantFiled: September 29, 1983Date of Patent: February 25, 1986Assignee: Toyota Jidosha Kabushiki KaishaInventors: Kiyoshi Funatani, Tadashi Donomoto, Atsuo Tanaka, Yoshiaki Tatematsu -
Patent number: 4545419Abstract: A device for manufacturing vehicle wheels having a rim which is wreath-shaped in cross section surrounding a cast wheel body is such that at least one die wall delimits the mold to be filled with cast metal. The prefabricated rim is laid between facing surfaces of a die plate and a center plate with the result that the die faces and the rim form the outer contours of the wheel body when the mold space between the die faces and rim is filled with molten metal which is introduced into the mold space under pressure. The rim itself is held by a clamping ring and can be removed in two pieces from the die assembly. A device for spraying a cooling medium onto the rim is provided on or in the clamping ring. The rim features on its inner face a central strut which is T-shaped in cross section, and on both sides of the actual struts are side struts which are inclined outwards. The free ends of the side struts are displaced by the surface of the die plates.Type: GrantFiled: January 12, 1981Date of Patent: October 8, 1985Assignee: Swiss Aluminium Ltd.Inventor: Herbert Zulauf
