Since the sand mold top surface sensor is disposed over an end of the conveyer apparatus on an upstream side with respect to the casting take-out apparatus, the casting take-out apparatus can be guided to an optimum casting take-out position calculated from a sprue position which is detected by the sprue position detecting apparatus. As a result, it is possible to automate the flaskless casting line as well as the following handling operation.

  • Patent number: 4993474
    Abstract: In a die casting apparatus, mold opening/closing units are mounted on carriers and the carriers are freely moved in/out from a mold clamping unit in a lateral direction. The mold clamping unit includes at least two guides for guiding each of the carriers from a standby position to a predetermined position in the mold clamping unit and a stationary board having a higher portion formed at a portion sandwiched by the guides. Each of the carriers includes a lift unit for moving upward/downward the mold opening/closing unit. When each of the carriers is to be moved, the lift unit positions the mold opening/closing unit at a height at which the mold opening/closing unit can freely move without colliding against the higher portion, moves the mold opening/closing unit into the mold clamping unit, and then moves downward and places the mold opening/closing unit on the higher portion of the stationary board.

  • Patent number: 4956008
    Abstract: An apparatus for superplastric forming of metallic workpieces and, more particularly, aluminum workpieces is disclosed. The apparatus includes a mechanism for ejecting the workpiece from the die upon completion of the superplastic forming process. A steel liner covers the surface of the die cavity, and the workpiece is formed against the liner (which acts as a die surface). The steel liner has high temperature resistance at superplastic forming temperatures providing it with sufficient rigidity to enable it to be removed from the cavity at or near superplastic forming temperatures while still retaining its shape and that of the formed worpiece which it supports. In one embodiment, a cam operated ejection mechanism pushes the liner from the die cavity surface as desired at the end of the superplastic forming process. In another embodiment, the die is provided with apertures through which pressurized gas is directed toward the liner pushing the liner away from the die cavity surface.

  • Patent number: 4795124
    Abstract: An article extracting means which is mounted on a carriage means which in turn is slidably mounted on the side of an article forming machine having two members movable relative to one another to form an article between them. A pivoted extractor arm in mounted on the carriage means to pivot in a vertical plane toward and away from the forming machine. An upper portion of the extractor arm carries an independently pivoted arm which may move in the same vertical plane as the extractor arm between at least two 180 degree opposed positions related to positioning gripping members carried thereby between an article gripping and an article release positions. The gripping members feature a construction wherein opposing jaw members are moved in a parallel direction toward and away from one another. One jaw member is actuated in a linear direction which via a rack and pinion arrangement cause the other jaw to move in parallel, but opposing direction.

  • Patent number: 4754801
    Abstract: A die casting machine in which a rotary table, mounted with a plurality of die open and close units each holding a die, is sequentially brought into association with a plurality of work stations. The die is clamped in two steps, that is, a regular die clamping and a temporary die clamping. The regular die clamping is carried out by applying the regular clamping force required by a particular injection step. The temporary die clamping is carried out by applying a clamping force which is smaller than the regular clamping force. Consequently, this die casting machine can greatly reduce the time required for the casting cycle for each product, thus providing remarkably improved productivity. Preferably, a metal cooling apparatus suitable for a rotary die casting machine may be further provided.

  • Patent number: 4655273
    Abstract: In an ingot mould casting device for casting a melt, the ingot moulds (1, 1a, 1b) of the individual ingot mould units (35, 36, 37) are movable in a U-shaped clamp (13), wherein at the free ends (43) of the U-shaped clamp (13) there is provided an ingot mould holding- and pulling-apart mechanism. With the aid of this ingot mould holding-and pulling-apart mechanism, the ingot moulds are opened so far, after casting has been effected in the casting position, until the resistance during pulling-apart of the ingot mould (1, 1a, 1b) drops to the resistance with respect to the shifting of the ingot mould half (1b) movable on the guide rods (2). In a second phase, the movable ingot mould half (1b) is moved completely away from the non-movable ingot mould half (1a). The discharged parts fall onto the conveyor belt (18). The entire operation from the actuation of the starting button (42) of an ingot mould arrangement can take place automatically.

  • Patent number: 4643243
    Abstract: A machine for repeatedly impacting metal castings in order to clean the castings of debris, such as sand, is formed of a wheel-like frame which is rotatably mounted upon a horizontal axle. The frame is divided into four equally spaced apart compartments which provide two pair of opposed compartments. The radially innermost wall of each compartment is formed of a metal plate arranged parallel to the axle so that the plate of the uppermost compartment is horizontal and forms a floor-like support for the casting which is then located in that compartment. Each plate is loosely supported upon springs and has an exposed end portion that extends transversely outwardly of the frame. An impact hammer is arranged to repeatedly apply blows that are directed radially towards the axle against the exposed end portion of the uppermost plate for vibrating the plate and for transmitting the forces of the blows to the casting for loosening debris clinging thereto.

  • Patent number: 4501313
    Abstract: In a foundry apparatus for clearing sand from castings comprising a conveyor and a supporter for the castings and for moving them from the conveyor into an abrasive blasting cabinet (or other sand removing unit) while turning the castings about a horizontal axis, in order to make transport simpler and to make certain that even complex castings are completely cleaned, a transport unit is used for taking up and supporting the castings and is supported on the supporter. The transport unit has a platform-like lower support in the form of a grid to be joined to the supporter by mating parts on the supporter and on the lower support. The mating parts are designed to keep the lower support in a generally horizontal position. The transport unit further is designed for forming a basket with a keeper element on the supporter and the basket is able to be opened and shut.

  • Patent number: 4411579
    Abstract: An improvement in the ejection means or ejection station of the machine described in U.S. Pat. No. 4,133,625. The improved structure employs a finger with a resilient (e.g. rubber) face or a similar striking instrument to strike the inside of the cup, tub or other hollow object being made and knock it loose and into a predetermined trajectory so that the product can be recovered with no damage to its finish. In accomplishing this, the finger is mounted on a vertically moving yoke that engages the carrier plate-tip ring assembly to which the product is temporarily adhered. With this construction, the finger strikes the product and knocks it loose during motion of the frame.
