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: 6938671Abstract: A multiple-slide die-casting machine is equipped with improved mechanical structure and unique injection control system to improve the quality of molded products, to achieve flash free castings of improved surface finish. The clamping assemblies are mounted on one side of a base plate of the machine for applying clamping force to the mold sections in a preloaded state. A reinforcement ring interconnects the clamping assemblies to inhibit deflection of the base plate and the brackets which support the clamping assemblies so that an accurate parting line between the contacting surfaces of mold sections is insured.Type: GrantFiled: July 9, 2004Date of Patent: September 6, 2005Assignee: Techmire Ltd.Inventors: Alexandre A. Pollak, Carl Thibault, Alain Bourbonnais, Richard Laveau
