  • Patent number: 10926322
    Abstract: A die casting machine with a die casting mold produces metal die cast parts. The die casting machine has a first machine shield, to which a first mold half of the die casting mold is secured, and a second machine shield, to which a second mold half of the die casting mold is secured. In order to compensate for the deflection of the machine shields, an intermediate plate which has at least two temperature-controlling devices that can be used to generate a temperature difference leading to the curving of the intermediate plate is arranged between the first machine shield and the first mold half and/or between the second machine shield and the second mold half.

  • Patent number: 10919087
    Abstract: The moulding machine includes a moulding chamber having at least one chamber end wall (8) provided with a pattern plate adapted to form a pattern in a mould part and associated with a reference pattern block positioned in fixed relationship to a pattern of said pattern plate and adapted to form a reference pattern in an external face of a mould part. A detection system detects the position of a pattern face of the reference pattern of the sand mould part. A transverse and/or a rotational compaction position of a pattern plate is adjustable by means of at least one actuator (91, 92, 119). Said actuators are controlled by means of a control system on the basis of successive position detections performed by the detection system of pattern faces of reference patterns of compacted sand mould parts travelling along said path of travel.

  • Patent number: 10906567
    Abstract: A process for producing a coupler knuckle and an improved coupler knuckle design are provided. The process produces a coupler knuckle by constructing a mold having the shape of the coupler knuckle. The mold is coated with a material that is resistant to melting at the molten melt temperatures of the molten metal used to form the knuckle. With the mold coated, the cavities in the mold interior are filled by placing an inert material therein. The molten metal used for forming the knuckle contacts the mold and consumes it, while the coating serves to provide a shape for the knuckle.

  • Patent number: 10906093
    Abstract: A continuous casting device having multi-stage convergence control is disclosed. Cooling surfaces of the continuous casting device can be articulated in stages, providing individual convergence control to longitudinally spaced-apart regions of the casting cavity. In a proximal region, during which the molten metal exhibits solidification shrinkage, a first convergence profile can be used to optimally account for the solidification shrinkage. In a subsequent distal region, a second convergence profile can be used, such as to provide optimal control of exit temperature of the continuously cast article. Multi-stage convergence control can be achieved through individually articulatable cooling pads or other supports positioned opposite the cooling surfaces from the casting cavity to displace the cooling surfaces and thereby adjust the convergence profile of the casting cavity.

  • Patent number: 10894286
    Abstract: A high-pressure die casting apparatus including a shot sleeve extending through a first die half to a molding surface, and a plunger received in the shot sleeve is provided. The shot sleeve includes a side wall presenting a fluid passageway and a partial end wall disposed in a fixed position relative to the side wall. The partial end wall defines a wall opening adjacent the molding surface. Fluid is poured into the shot sleeve while the die apparatus is open, and the partial end wall prevents the fluid from flowing out of the shot sleeve. The plunger then presses the material into the mold cavity until only a portion of the material remains in the shot sleeve and blocks the wall opening. After the solidified material is ejected from the apparatus, the portion of material blocking the wall opening prevents lubricant from entering the shot sleeve.
