Definitions

  • the present invention relates to a casting spoon, which is especially suitable for use in metal casting machines in sand molds, a spoon that has been conceived and structured in order to facilitate the entry of molten metal into the sand mold , without the need to pressurize the spoon for the transfer of said metal.
  • the molding machines of motorcycles basically comprise a molding chamber, fed by a sand hopper established in the upper part, said chamber being closed by a movable and tilting front plate and by a rear plate provided at one end of an extractor piston, performing the compaction of the sand by opposing pressure of both dishes.
  • a vertical molding machine is described in PCT ES 01/00224, which the applicant entity itself owns, a machine that includes a station with a chamber that closes between a front plate that is movable and tiltable and a plate posterior associated with an extractor piston, forming a speck in said chamber by blowing sand through a hopper or upper hood.
  • the speck obtained is pushed by a piston towards a rear area of the row of specks located on a conveyor that faces them at a casting station.
  • the movement of the motes pushed by the extractor piston is independent of their movement once incorporated into the row of motes, where said movement is produced exclusively by a galloping type conveyor system, which allows a reduction in cycle time working, while avoiding damage to the specks, not being crushed by the aforementioned piston in its thrust against the back of the row of specks.
  • a casting station appears in turn in the PCT ES 00/00013, also of the applicant itself, which has the special feature that in addition to having a main casting channel, which accesses the mold through the lower part thereof, incorporates a vertical and external secondary channel to the mold, which ends at the top of the latter, where the corresponding flask is established, so that once the molten metal has filled the mold the main casting channel is sealed and followed by feeding the molten metal through the secondary channel, until the upper tap is filled, for all of which a pressurized pouring spoon is used, since said spoon is located below the lower level of the mold.
  • the pouring spoon that the invention proposes applicable to casting stations such as the one of the PCT ES 00/00013, solves in a completely satisfactory way the problem previously exposed, constituting a simple and effective solution, which without supposing any problem at the time of incorporating the molten metal of said spoon, allows it to be transferred to the mold by simple gravity, specifically by the effect of the "communicating vessels", by means of a tilting assembly for it that allows it to adopt a horizontal position during its filling and a position vertical during emptying, that is, during filling of the mold.
  • the spoon itself is assisted by a platform or support structure, with lateral displacement to join and separate from the mold line, and on said platform the spoon is mounted with the possibility of tilting, with the particular feature that its axis of tilting coincides positionally with the loading mouth of the molds, so that said tilting movement does not interfere with the perfect communication between bucket and mold, achieving the bucket swinging movement with the collaboration of a cylinder, preferably hydraulic, which at Through a cardan joint and a connecting rod it transmits the movement to the bucket's tilt axis.
  • the spoon itself is provided with a loading mouth and a metal housing that surrounds or wraps the construction of refractory material and is capable of withstanding the high temperatures of the broth.
  • Figure 1. It shows a schematic representation in side elevation of a casting spoon duly coupled to the mold line of the casting station, the spoon appearing in a filling position thereof.
  • Figure 2. Shows a representation similar to Figure 1, but in which the spoon adopts the unloading or filling position of the corresponding mold.
  • Figure 3. Shows, finally, a plan view of the assembly shown in Figure 1, together with the accessories for the mobilization of the spoon.
  • Figure 4. Shows three schematic views of the direct coupling between spoon and mold.
  • Figure 5. It shows, finally, a schematic view of the arrangement between spoon and mold when between them there are intermediate bushings that facilitate the rotation of the spoon with respect to the mold.
  • the pouring spoon that the invention proposes is intended to be positioned laterally with respect to the mold line (1), and consists of a receptacle (2) with its corresponding filling mouth (3 ) and outlet duct (4) finished off in the corresponding hole (5) facing the entrance to the molten metal feed channels to the mold, with the particular feature that said outlet duct (4), in the initial situation , resting and filling the spoon (2), the one shown in figure 1, adopts an upwardly inclined arrangement, so that the outlet opening (5) is located above the level of the molten metal (6) that constitutes the maximum expected dose for said spoon.
  • the filling of the mold is carried out by simple tilting of 90 ° of the spoon, which goes on to adopt the position represented in Figure 2, in which the receptacle (2) of the spoon, by the length of the outlet duct (4), which mostly houses molten metal (6), is located above said mold and in a position to fill the latter completely above its mazarot, by simple gravity.
  • said spoon does not interfere with the advance of the mold line (1)
  • said spoon is mounted on a platform or support structure (7), laterally movable on guides (8) with respect to the line (1), in order to approach and distance from it, platform (7) on which a hydraulic cylinder (9) is mounted which, with the collaboration of a cardan-type joint (10) and a connecting rod (11), supplies the bucket support (2) to the shaft (2) with the necessary tilting movement to move from the position shown in figure 1 to the of figure 2 and vice versa, shaft (12) mounted on bearings (13) and which, as previously mentioned, coaxially coincides with the outlet or pinhole (5) of the duct (4) of the bucket.
  • FIGs 4 and 5 finally show schematically the connection between the spoon (2) and the mold line (1), in the first solution, that of Figure 4, the spoon spike or exit hole (4 ), it sits on the sand mold with an adjustable pressure and rotates that bite on the mold sand itself.
  • bushings are of a special material that withstand high temperatures, such as ceramic materials, compact graphite, etc.

Abstract

L'invention a trait à cuiller de coulée à utiliser dans une ligne de production et de remplissage de moules (1) de sable. Ladite cuiller (2) est basculante, de manière à recevoir en position horizontale la dose de métal liquide (6), et à verser en position verticale par effet gravitationnel ledit métal liquide à l'intérieur du moule. Le logement (2) de la cuiller est pourvu d'un long conduit de sortie (4) incliné vers le haut et dont l'extrémité est pourvue d'un orifice (5) qui communique avec l'orifice d'accès à l'intérieur du moule. Cet orifice de sortie (5) coïncide avec l'axe de basculation de la cuiller, de sorte que, lorsque celle-ci est en position verticale, le logement (2) est placé au-dessus du moule et le métal liquide (6) remplit ce dernier par effet gravitationnel, c.-à-d. par ≤ vases communiquants ≥.
