Patent number: 10682695Abstract: A method for casting metal using a semi-permanent mold connected to a feed portion includes forming a coolant jacket in a sprue of the feed portion. A coolant source is connected to the coolant jacket. A metal in a molten state is poured into the feed portion for gravity induced flow into the semi-permanent mold. A wall thickness of the sprue is predetermining which minimizes heat transfer from the sprue, thereby forcing the metal in the molten state to cool slower in the sprue than in the mold. After a predetermined time for the metal to cool to a solid state in the mold, flow of a coolant from the coolant source into the coolant jacket is initiated to cool the metal in the sprue before opening the mold.Type: GrantFiled: May 7, 2018Date of Patent: June 16, 2020Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: David D.

Publication number: 20080187454Abstract: A heat-resistant magnesium alloy is for casting, and includes Ca in an amount of from 1 to 15% by mass, Al in a summed amount of from 4 to 25% by mass with the amount of Ca, and the balance being Mg and inevitable impurities when the entirety is taken as 100% by mass. The heat-resistant magnesium alloy is not only inexpensive, but also effects an advantage that cracks are inhibited from occurring when being cast. For example, a process for producing heat-resistant magnesium alloy cast product includes the step of pressure pouring an alloy molten metal, which has a target composition around Mg-3% Ca-3% Al-from 0.2 to 0.3% Mn, into a cavity of metallic die, which is preheated to a die temperature of from 130 to 140° C. in advance. The process makes it possible to produce die-cast products, which are free from cast cracks.Type: ApplicationFiled: October 18, 2007Publication date: August 7, 2008Inventors: Motoharu Tanizawa, Kyoichi Kinoshita, Eiji Kishi, Katsufumi Tanaka, Yuki Okamoto, Takayuki Kato

Publication number: 20080182122Abstract: Molten metal is injected uniformly into a horizontal mold from a feed chamber in a horizontal or vertical direction at a controlled rate, directly on top of the metal already within the mold. A cooling medium is applied to the bottom surface of the mold, with the type and flow rate of the cooling medium being varied to produce a controlled cooling rate throughout the casting process. The rate of introduction of molten metal and the flow rate of the cooling medium are both controlled to produce a relatively uniform solidification rate within the mold, thereby producing a uniform microstructure throughout the casting, and low stresses throughout the casting.Type: ApplicationFiled: March 31, 2008Publication date: July 31, 2008Inventors: Men G.
