Patent number: 8118080Abstract: By pouring, by means of pressure, melted liquid of magnesium or magnesium alloy into a hollow portion which is formed using a casting mold, a valve body where a channel groove for hydraulic oil for use in a speed change operation of the automatic transmission is formed. In the above, the channel grove for the hydraulic oil is formed due to a convex portion which is formed on the mold so as to project into the hollow portion. As the magnesium has small heat capacity, variation of the temperature of the mold during the cooling and heating cycle can be suppressed. Moreover, as the magnesium melted liquid has no reactivity with respect to the casting mold, the convex portion is not deteriorated. This allows employment of a mold having a thinner convex portion formed thereon, and therefore formation of a valve body having a narrower channel groove.Type: GrantFiled: August 30, 2010Date of Patent: February 21, 2012Assignee: Toyota Jidosha Kabushiki KaishaInventors: Toshihiro Aoyama, Shinichi Itou, Akira Murakami, Tomoyasu Kitano

Publication number: 20100252222Abstract: The casting device (1) comprises a die (3) consisting of two die halves (3a, 3b) forming in their interior a die cavity (4). In addition, the casting device (1) comprises connected to the die cavity (4) a casting chamber (6), the outlet (9) of which can be closed off at least partially by means of a closure member (18,26). At least the one die half (3a) is provided with a vent passage (13) for evacuating the die cavity (4) and/or the casting chamber (6). The vent passage (13) ports into the die parting (12) of the one die half (3a) such that it can be closed off by the other die half (3b) when locking the die (3).Type: ApplicationFiled: April 6, 2010Publication date: October 7, 2010Applicant: FONDAREX S.A.Inventor: Konrad Baumgartner

Publication number: 20100243191Abstract: In a cylinder block manufacturing method, first and second dies and a liner support are provided to form a liner overcast configuration. The first and second dies are positioned with respect to the liner support and a dummy cylinder liner made of an aluminum alloy such that the first die contacts a pressing section of a first axial end of the liner support and a first axially facing end of the dummy cylinder liner, and the second die contacts a second axial end of the liner support and a second axially facing end of the dummy cylinder liner. The first and second dies are preheated to a prescribed temperature with the dummy cylinder liner positioned on the liner support by injecting molten aluminum alloy into a cylinder block molding cavity to form a dummy cylinder block with the dummy cylinder liner casted in the dummy cylinder block.Type: ApplicationFiled: February 24, 2010Publication date: September 30, 2010Applicant: AICHI MACHINE INDUSTRY CO., LTD.Inventor: Yoshinori NISHIKAWA

Patent number: 7802612Abstract: In a die-casting mold used in a casting method, a fixed insert includes a recessed cavity portion, and a fixed mold body is arranged to hold the fixed insert. The fixed insert includes a first insert and a second insert. The first insert is held with the fixed mold body. The second insert is fitted and held within a recess formed on the first insert. The size of the second insert is minimized so as to just surround the recessed cavity portion.Type: GrantFiled: July 31, 2006Date of Patent: September 28, 2010Assignee: Yamaha Hatsudoki Kabushiki KaishaInventors: Hiroshi Yoshii, Kimitoshi Satou, Takayoshi Inamura

Patent number: 7770626Abstract: A release agent spray method and apparatus for a die casting machine. As a movable die plate is moved in a die closing direction, a spray head is moved in a perpendicular direction to a spray position. The movable die plate is stopped when it has reached a position at which the distance between the spray head and a die cavity surface of a movable die and the distance between the spray head and die cavity surface of a fixed die both become equal to a spray distance. A release agent is sprayed from the spray head onto the cavity surfaces of the movable die and the fixed die.Type: GrantFiled: December 22, 2006Date of Patent: August 10, 2010Assignee: Toshiba Kikai Kabushiki KaishaInventors: Masaki Yashiro, Hiroshi Yokoyama

Patent number: 7766070Abstract: A method for operating an automated reciprocator for applying lubricant in a die casting system. As a reciprocator is moved between two die halves and a fluid is applied to the dies with the reciprocator, a safety bar is moved ahead of the reciprocator. Any objects in the path of the reciprocator are detected by contact with the safety bar. If the safety bar contacts an object as the reciprocator is moving down, a sensor signals a control system and the reciprocator is stopped.Type: GrantFiled: April 13, 2009Date of Patent: August 3, 2010Assignee: Pace Industries, LLCInventors: David R. Thomason, David E. Bumpus, Danny S. Alford, Olen L. Marshall
