  • the device according to the present invention is preferably used in combination with a hopper which is pivotably mounted to locate directly overhead of a casting sleeve of a die casting machine and the shaking movement of the hopper is coupled with the transfer movement of the ladle.
  • the shaking movement of the hopper may be provided by means of a pressure cylinder.
  • the device of the present invention can achieve such effects as follows:
  • An amount of molten bath to be fed is determined by an angle of inclination of the ladle so that a precise amount of bath can be fed.
  • the heat insulating furnace or the melting furnace can be of the open-air type with its upper part completely uncovered so that the molten bath or ingots can be supplied very simply.
  • the device has a very simple construction and the ladle is the only part which is required to submerge in the molten bath. Consequently maintenance of the device is very simple. In short, the ladle can easily be replaced with a reserve ladle or by any other adequate ladle in case it becomes necessary to take out a larger amount of molten bath.
  • the ladling device according to the present invention may be installed in any common furnace without any troubles. Yet its manufacturing and installation costs are held very low.
  • FIGURE 1 is a vertical cross sectional view of one embodiment of the device according to this invention.
  • FIGURE 2 shows a cross section of the device on the line llII on FIGURE 1.
  • FIGURE 3 shows a cross section of the device on the line IIIIII on FIGURE 1.
  • FIGURE 4 shows a cross section of the device showing operative condition of a ladle according to this invention.
  • a pan 1 is provided in a heat insulating furnace or a melting furnace 2 and in the pan is contained molten bath of metals 3.
  • molten bath of metals 3 When the level of the molten bath decreases, additional molten metal is supplied in a state of bath for a heat insulating furnace while ingot is supplied for a melting furnace.
  • a ladle 4 is fixed by means of bolts 5 to a ladle fixing plate 6 and has a construction adapted to be easily replaced.
  • the ladle fixing plate 6 is fixed to a chain wheel 7 to which is fitted also a shaft 8 in a rotatable manner. On one end of an arm 9 is fitted the shaft 8 and on the other end thereof is fitted a drive shaft 10.
  • a chain wheel 11 fitted on a rotary frame 12 in such a manner that said chain wheel 11 is disposed concentrically with the drive shaft 10.
  • the chain wheel 7 and the chain wheel 11 are connected by means of chains 13 and 14.
  • a worm wheel 16 is provided on the drive shaft 10, said worm wheel being meshed with a worm 17 driven by a hydraulic motor 18 provided on the rotary frame 12.
  • a hydraulic cylinder 24 is fitted by means of a pin 25 to a bracket 26 on the support base 20 so that said hydraulic cylinder can oscillate freely.
  • One end of a piston rod 27 of the hydraulic cylinder 24 is fitted at a projection 12A of the rotary frame with a pin 28.
  • a hopper 29 directly above a casting sleeve 30 of the die casting machine and for this purpose said hopper is fixed at a hopper seat 31 by means of a pin 32 to be capable of oscillating, and said hopper seat 31 is attached to a fixed platen 33 of the die casting machine by bolts 34. Furthermore, a bracket 35 is fitted on said fixed platen 33 by means of bolts 36, and on this bracket 35 a air cylinder 37 is oscillatorily fitted by a pin 38.
  • the projection 29A of the hopper 29 is provided at a piston rod 39 of the air cylinder with a pin 40 so as to freely oscillate.
  • 41 is a plunger tip for casting the molten metal 3 in the casting sleeve 30 into a metallic mold (not shown).
  • 42 is a plunger rod.
  • FIGURES 2 and 3 denotes a position of the ladle 4 when the ladle is tilted from the position of (B) by throwing down rotary frame 12 from the position of (B) and to discharge the molten bath into the hopper 29.
  • D in FIGURES 2 and 3 shows a position taken at random by the rotary frame 12 when the latter has turned upright after feeding of bath has been accomplished.
  • the worm 17 and worm wheel 16 can be substituted with other common rotary drive means; the chain wheel 11 with a fixed circular body; and the chain wheel 7 with a circular" rotary means.
  • the chains 13 and 14 can be substituted by wire rope and the like.
  • the ladle 4 as shown by (A) in solid line in FIGURE 1 lies below the surface of the metal bath 3.
  • the rotary frame 12, as shown in FIGURES 2 and 3 is located at a position of (D) which makes an angle of 0 with the position of (B) so that the ladle 4 is tilted through the angle 0 and dipped in the metal bath 3, i.e., the ladle will lie in the metal bath 3 in the state shown by (a) in FIGURE 4.
  • the ladle 4 moves maintaining the same posture irrespective of the position of the arm 9 wherever it is situated.
  • the ladle 4 rises up from the surface of the molten bath while maintaining its inclination at an angle of 0.
  • the surface level of the bath lies at a position of (M) which is the lowest point on the edge of the ladle 4. In this state, the amount of bath to be fed is measured. Therefore by varying the inclination angle of the ladle 4 or the angle 0 it is possible to adjust the amount of bath to be fed desirably.
  • the pressure oil enters the upper part of the hydraulic cylinder 24 by means of electric signals and the piston rod 27 is pushed down so that the rotary frame 12 turns in counterclockwise direction around the shaft 22 and stops at a perpendicular position.
  • the ladle 4 too restores a vertical posture from an inclined one, and the surface of the molten bath in the ladle 4 comes to the extent of (H) as shown in FIGURE 4 ,(C), thus preventing the spilling of the molten bath which may otherwise result from the oscillation of the ladle in operation.
  • the ladle 4 When flowing of the molten bath into the casting sleeve 30 is finished, the ladle 4 returns to the former position. Thereupon the hopper 29 comes back from the position of (F) to that of (E) thereby to prevent from falling into the casting sleeve 30 the solidified metals and impurities which have been adhered onto the outside of the ladle 4 during the process of casting.
  • a device for ladling a molten bath of metals comprising: a support base, a frame pivotally mounted on said base about a first axis, an arm pivotally mounted on said frame about a second axis perpendicular to said first axis, a drive means connected to a power source and disposed on one end of said arm, a circular body fixed on said frame concentric with said second axis, a circular rotary means fixed with a ladle and being pivotally mounted on the other end of the arm, endless chain means mounted between the fixed circular body and the circular rotary means, said drive means being connected to pivot said arm whereby the ladle is moved with its surface maintained in a horizontal position by an ellipsoidal movement of the chain means by means of the fixed circular b body and the circular rotary means for the ladling of the molten bath of metals, in combination with means for inclining the ladle including a hydraulic cylinder and piston rod pivotally mounted on said support base and pivotally connected to said frame.
