Definitions

  • the present invention relates to a system of coolers foreseen for its use in sand casting moulds to achieve the cooling of certain parts of the cast pieces that are obtained.
  • the coolers are foreseen for their application in the obtaining of, for example, engine blocks obtained by casting aluminium in sand moulds, with the object of achieving an enhancement of the metallurgical properties in certain areas of the obtained piece.
  • the coolers will be mounted On a cooler holder and fastened to this in such a way that they form a multiple cooler that facilitates their automated assembly on the corresponding mould, as well as their extraction with respect to the casting, with return to the assembly area. Also part of the object of the invention are the means that intervene in the assembly/disassembly process.
  • coolers that are arranged in certain areas of the casting mould, all of which is for the purpose of having the poured aluminium cool more quickly in the zone in contact with the cooler, thereby improving the metallurgical properties of the piece in those areas that have cooled more quickly.
  • coolers In the casting of aluminium engine blocks, the use of coolers is known to cool more quickly those parts of the piece that will constitute the seat of the crankshaft, the coolers being constituted on the basis of a cylindrical body of cast iron that is placed in the mould before the metal is poured, with the object that said cylindrical body causes quicker cooling in the partitions that will conform the seat for the crankshaft.
  • the cooler only acts on the surface of the piece that will be in contact with it, so that its effectiveness is limited practically to one side of the piece.
  • the cores are placed inside the sand mould and subsequently the coolers, the latter being positioned and secured in the most convenient and opportune way.
  • the metal is poured into the mould, the latter passing to the cooling station and then to the de-moulding station.
  • the de-moulding of the casting can be carried out by means of vibration, although at present it is carried out by means of a heat treatment that causes the melting of the binder resin, loosening the sand and producing the destruction of the mould in a simple manner, all of this such that after said destruction of the mould the casting will be obtained which will continue on its way to receive the treatments it requires, and moreover the sand with the coolers, sand which before returning it to the recovery plant thereof, it is necessary to separate from the coolers, an operation that is generally carried out by vibration. Said operation of separating the sand from the coolers requires time and appropriate means to carry it out, which results in an additional economic cost.
  • coolers The system of coolers that is proposed, has been conceived to resolve the problem explained above, it being foreseen that the cooler as a whole is multiple and is mounted on a cooler holder, so that all the units or modules that constitute the cooling assembly are joined or anchored to the cooler holder, by means of a bar or similar element, what permits that the assembly of the multiple cooler on the mould, as well as its disassembly, can be carried out automatically, since the cooler holders will be mounted on a pallet that can be handled by robotic means moveable on the production line, the same as the mould transporting pallet.
  • Each unit or module of the cooler will be materialized in one, two or three pieces, positioned in such a way that between them a certain play is determined to absorb possible expansions and contractions.
  • the positioning of the coolers on the corresponding support or cooler holder will be carried out also with a certain play, with the object of likewise absorbing the expansions and contractions that are caused by the heat or temperature rise transmitted by the molten metal.
  • coolers are constituted by two or more pieces, on one hand, the absorption of expansions and contractions will be facilitated and, on the other, the play between the parts that form each unit of the cooler constitutes escape paths for the air when pouring the molten metal, the operation of filling the mould being facilitated, even in the corners or at conflictive points.
  • coolers of the invention Another feature of the coolers of the invention, is that the design thereof is such that they partially envelope the piece to be obtained, whereby the contact between the latter and the cooler not only affects the front area of one of its faces but extends likewise to part of its sides, achieving the cooling on said frontal and lateral parts.
  • the function installation that operates with the type of coolers according to the system of the invention, carries out first a transfer of the mould for cooling, and subsequently an extraction of the cooler and corresponding separation and evacuation with regard to the casting, the transport of the coolers being carried out to the station for placement and insertion in the mould, after previously passing through a treatment area in which the cleaning and painting are carried out, as well as other operations on the cooler itself.
  • the system of coolers object of the invention is foreseen for its assembly on a sand mould, the latter being located on a pallet (1) which is superimposed and fastened, by means of corresponding keys (2), to a pallet (3) below to which is fastened the support (4) or cooler holder, the latter being constituted by the modules or units (5), as is shown in figure 1.
  • the sand mould comprises the cover or top core (17), the base or bottom core (18) and the core assembly (19) that forms the frame.
  • the modules or units of coolers (5) that can be constituted by a single piece, by two pieces (5') or by three pieces (5"), as is represented in figure 3, so that in any case the cooling units or modules (5) are mounted with a certain play (6) on the support (4) and fastened to this by means of a bar or similar (7) that traverses transversally both the support (4) and all the modules or units of coolers (5), it having been foreseen also that these last come with a recess so that the cast piece (P) cools down, not only through its front face, but also through its side ones as is represented in said figure 3.
  • the modules or units of the coolers are designed to grasp the castings (P) by those parts that must receive the benefit of the use of the cooler, so that the cooling takes place not only on the front part of the piece (P), but also extends to the adjacent side parts.
