Publication number: 20150314369Abstract: The die casting machine comprises a mold closing actuator capable of selectively inducing a closing pressure on first and second platens for forcing them towards a closed position in which their mold portions are pressed against each other along a parting line. An injection sleeve is movable relative to the mold portions between a distal position in which the injection sleeve and the mold portions are spaced apart; and an injection position in which the injection sleeve engages the mold portions at an inlet opening when the first and second platens are in their closed position. The injection sleeve applies a transverse contact pressure when it engages the mold portions. The closing pressure is unevenly distributed on the platens so as to compensate the transverse contact pressure to have a resulting effective molding pressure on the mold portions that is substantially evenly distributed across the parting line.Type: ApplicationFiled: July 13, 2015Publication date: November 5, 2015Inventors: Stephane Bergeron, Alain Bourbonnais, Samuel Dubois, Richard Laveau, Gilbert Monette, Jean-Pierre Ouellet, Carl Thibault

Patent number: 7121321Abstract: An injection unit for a hot-chamber die-casting machine has an injection portion with a gooseneck and a nozzle adaptor. The injector portion has a base portion at an end of the gooseneck adapted to receive a molten medium supply. A nozzle at an end of the nozzle adaptor is adapted to inject the molten medium supply in a die cavity. A channel between the base portion and nozzle is adapted to convey the molten medium supply therethrough. A piston chamber in the base portion is actuatable to draw the molten medium supply therein and to direct the molten medium supply in the channel for injection into the die cavity. An actuation portion is connected to the gooseneck to actuate the piston chamber. Heating cartridges are received in the injection portion adjacent to the channel to control temperature of the molten medium supply in the channel.Type: GrantFiled: April 7, 2004Date of Patent: October 17, 2006Assignee: Techmire Ltd.Inventors: Carl Thibault, Jean-Pierre Ouellet, Irina Oluhova, Cyril Trincat

Patent number: 6978823Abstract: A multiple-slide die-casting machine for casting pieces has a frame. A table is operatively mounted to the frame. A slide guiding mechanism is secured to the table and has slides. Each slide has a die section. The slides are actuatable in a close/open action such that the die sections mate to form a die cavity. An injection unit is mounted to the frame and is adapted to be connected to a molten medium supply. The injection unit has a nozzle and is adapted to inject molten medium from the supply into the die cavity through the nozzle for casting a piece. A relative displacement configuration is provided between the table and the injection unit such that the die sections on the table are disengageable from with the nozzle for injection of a cast product from the die cavity.Type: GrantFiled: February 20, 2003Date of Patent: December 27, 2005Assignee: Techmire Ltd.Inventors: Carl Thibault, Jean-Pierre Ouellet, Irina Oluhova, Cyril Trincat

Publication number: 20040188054Abstract: A multiple-slide die-casting machine for casting of magnesium pieces, comprising a frame. A table is operatively mounted to the frame. A slide guiding mechanism is secured to the table and has slides. Each slide has a die section at an operating end thereof. The slides are actuatable in a close/open action such that the die sections mate at a parting line therebetween to form a die cavity. An injection unit is mounted to the frame and is adapted to be connected to a molten magnesium supply means. The injection unit has a nozzle and is adapted to inject molten magnesium from the supply means into the die cavity through the nozzle for casting a piece.Type: ApplicationFiled: April 7, 2004Publication date: September 30, 2004Inventors: Carl Thibault, Jean-Pierre Ouellet, Irina Oluhova, Cyril Trincat
