  • Patent number: 11892337
    Abstract: An opening portion that is formed so as to pass-through an opening/closing plate portion of a gate, can be disposed at a region overlapping a lower end opening of a hopper. The opening portion is structured by a first pass-through portion, and a second pass-through portion that is formed so as to be continuous with the first pass-through portion. A width, in a direction orthogonal to a lined-up direction in which the first pass-through portion and the second pass-through portion are lined up, is narrower than the first pass-through portion. Further, a driving mechanism moves the gate such that the opening/closing plate portion moves in the lined-up direction as seen in a plan view. Based on a preset target value of weight of sand, a control section controls the driving mechanism so as to decrease an amount of overlap of the opening portion of the gate and the lower end opening of the hopper in a stepwise manner in accordance with an increase in the weight of the sand measured by a scale.

  • Publication number: 20220352777
    Abstract: An axial-gap-dynamoelectric machine includes resin bobbins having positioning protrusions, and a stator core including a base yoke having a plurality of tooth holes and positioning holes. In each tooth hole, a circumferential length of a tooth-hole-radial-direction-outer-end surface is larger than a circumferential length of a tooth-hole-radial-direction-inner-end surface. Each of the plurality of teeth has a columnar shape in which a circumferential length of a tooth-upper surface is larger than a circumferential length of a tooth-bottom surface. The positioning protrusions are inserted in the positioning holes, and press the teeth against the base yoke inward in the radial direction such that the tooth-bottom surface is brought into contact with the tooth-hole-radial-direction-inner-end surface and the tooth-oblique surface is brought into contact with the tooth-hole-circumferential-direction-end surface.

  • Publication number: 20220345018
    Abstract: An axial gap motor having a rotor and a stator core. A plurality of pressed powder teeth extends in a radial direction of the stator core and each has a trapezoidal shape in which a circumferential length of a pressed-powder-tooth-radial-direction-outer-end portion is larger than a circumferential length of a pressed-powder-tooth-radial-direction-inner-end portion. The rotor includes a plurality of field magnets, each configured such that a circumferential length of a magnet-radial-direction-inner-end portion is greater than or equal to a circumferential length of a magnet-radial-direction-outer-end portion. When the rotor and the stator core rotate relative to each other about a rotation axis, a part of the field magnets first overlaps with pressed-powder-tooth-radial-direction-inner portions of pressed powder teeth, and while the field magnets are located at a q-axis position with respect to the pressed powder teeth, adjacent ones of the field magnets individually overlap with one pressed powder tooth.

  • Publication number: 20210268572
    Abstract: When molding surfaces (50A) of a pair of dies (50) are to be cleaned by air-blowing, air is blown towards the molding surfaces (50A) from blowing nozzles (22A) of a cleaning blowing function portion (22) while a moving body (16) is reciprocatingly moved by driving force of a driving mechanism (18). When a parting agent is to be applied to the molding surfaces (50A) of the pair of dies (50), the mold release agent is jetted out towards the molding surfaces (50A) from spraying nozzles (24A) of a parting agent application function portion (24) while the moving body (16) is reciprocatingly moved by the driving force of the driving mechanism (18). In both of these situations, at the same time as the treatment of the molding surfaces (50A), a cleaning brush (32) reciprocatingly moves together with the moving body (16) and sweeps a device floor surface (12).

  • Publication number: 20210270664
    Abstract: An opening portion (34) that is formed so as to pass-through an opening/closing plate portion (32) of a gate (30), can be disposed at a region overlapping a lower end opening (24A) of a hopper (20). The opening portion (34) is structured by a first pass-through portion (34A), and a second pass-through portion (34B) that is formed so as to be continuous with the first pass-through portion (34A). A width, in a direction orthogonal to a lined-up direction in which the first pass-through portion (34A) and the second pass-through portion (34B) are lined up, is narrower than the first pass-through portion (34A). Further, a driving mechanism (40) moves the gate (30) such that the opening/closing plate portion (32) moves in the lined-up direction as seen in a plan view.

  • Patent number: 10946436
    Abstract: When pressing kneaded sand in a kneading sand tank into a mold by a pressing member, a pressing force applied to a kneaded sand layer in the kneading sand tank is monitored and a moving position of the pressing member is monitored from when the pressing member starts to move. A pressing start time at which the kneaded sand starts to flow into the mold is identified based on the pressing force applied to the kneaded sand layer in the kneading sand tank, and a pressing starting position of the pressing member at the pressing start time is identified. As a result, the pressing start time and the pressing starting position of the pressing member when the kneaded sand starts to flow into the mold are accurately identified, so the reliability of a filling evaluation of the kneaded sand into the mold is improved.

  • Patent number: 10888919
    Abstract: A core forming device is equipped with a kneading tank in which raw materials of a core are kneaded, a raw material supply unit that supplies the raw materials to the kneading tank, a mold that accommodates a kneaded material including the raw materials kneaded in the kneading tank and that forms the core, a piston that injects the kneaded material into the mold, a position sensor that detects a position of the piston, and a control unit that controls a supply amount of the raw materials supplied to the kneading tank from the raw material supply unit. The control unit determines the supply amount of the raw materials based on a difference between the position of the piston upon completion of injection and a reference position of the piston.
