Definitions

  • the invention relates to a set of layers for producing a model for the manufacture of a part by non-permanent mold molding of refractory material.
  • the invention also relates to a non-permanent mold for the manufacture of a part by non-permanent mold molding.
  • the invention also relates to a method of making a model for the manufacture of a part by non-permanent mold molding of refractory material.
  • the invention finally relates to a method for manufacturing a part by non-permanent mold molding of refractory material.
  • non-permanent mold means a mold which is destroyed during demolding of a molded part in this mold. Unlike a permanent mold, a non-permanent mold is not reusable after demolding the part.
  • Such non-permanent molds are generally made of refractory materials.
  • refractory material denotes a material having a thermal resistance greater than that of aluminum and, preferably, greater than that of cast iron or steel. Refractory materials are, for example, sand or ceramic. The melting temperature of these materials is greater than the melting temperature of the material in which the piece is made.
  • non-permanent molds of refractory material known are lost wax molds.
  • model is meant an exact replica of the part to be manufactured.
  • the model is made of wax.
  • the model is coated with a refractory liquid.
  • the model is then parboiled so that the liquid dries and solidifies to form a shell around this model.
  • the model is then placed in a tank and then fully silted.
  • the sand is compacted to a solid structure that perfectly matches the contours of the model.
  • the structure formed by the sand and enclosing the model thus forms a non-permanent mold for the part to be manufactured.
  • the manufacture of a part by molding using these molds is performed by casting a liquid material at high temperature through a mold inlet that can be provided for this purpose.
  • the liquid material is liquid aluminum.
  • the high temperature of aluminum causes the sublimation of the wax.
  • the aluminum then flushes the wax out of the mold and occupies the part formerly occupied by the wax. After cooling the aluminum until solidification, the final piece can be released by breaking the mold.
  • the invention aims to solve one or more of these disadvantages.
  • the invention proposes to protect the functional projections from shocks or friction by arranging non-functional projections so that when the layer is stored, these non-functional projections are more exposed to shocks and friction than the functional projections. Thus, they protect the functional projections from shocks and friction
  • the figure 1 illustrates a non-permanent mold 2.
  • This mold 2 comprises a tank 4 containing a refractory material 6.
  • the refractory material 6 is sand.
  • the mold 2 also comprises a model 8.
  • This model 8 is a replica of a part to be produced by molding.
  • the model 8 is immersed in the refractory material 6.
  • This model 8 is preferably made of a material whose melting temperature is lower than the melting temperature of the material in which the part is manufactured.
  • the model 8 is a model for a breech of a engine of an aluminum vehicle.
  • the model 8 is made of polystyrene.
  • Model 8 has several layers stacked on top of each other.
  • the description is made in the particular case where the model 8 comprises only two layers 10 and 12 capable of being stacked in a stacking direction 14.
  • the two layers 10 and 12 extend essentially in two planes parallel.
  • the stacking direction 14 is perpendicular to these planes.
  • the mold 2 also comprises a junction bar 13 providing the junction between the model 8 and a second model 9.
  • the model 9 is identical to the model 8.
  • the connecting bar 13 is in the same material as the models 8 and 9.
  • the connecting bar is polystyrene.
  • the assembly formed by the models 8 and 9 and the connecting bar 13 is designated by the term "cluster".
  • the cluster is connected to a power system 13A. This includes an orifice through which liquid aluminum can be cast.
  • the power system is a funnel.
  • the funnel communicates with the cluster via the connecting bar.
  • the figures 2 and 3 further illustrate a portion of the stratum 10.
  • This includes a bonding seal 15.
  • bonding seal is meant the surface of the upper face of the stratum 10 in contact with the stratum 12 when the strata 10 and 12 are stacked in the stacking direction 14.
  • the upper face of the stratum 10 also includes functional projections 16 and 18.
  • functional projection is meant a protrusion which is in contact with the refractory material 6 when the strata 10 and 12 are stacked and that the model 8 is immersed in this refractory material 6.
  • the functional projections are thus protrusions that affect the final shape of the part made with the mold 2.
  • the projections 16 and 18 extend for example according to In this example, the projections 16 and 18 are ports communicating with the outlet of tubings of an internal combustion engine.
  • the upper face of the stratum 10 also comprises non-functional projections 20, 21 and 22.
  • non-functional projection is meant a protrusion that is not in contact with the refractory material when the strata 10 and 12 are stacked and that the model 8 is immersed in the refractory material.
  • the projections 20, 21 and 22 are such that when the upper face of the stratum 10 is disposed on a flat surface, the stratum 10 rests solely on the projections 20, 21 and 22 rather than the projections 16 and 18.
  • the flat surface is for example the face of a plan for storing the strata.
  • the projections 20, 21 and 22 thus make it possible to limit the friction between the projections 16 and 18 and this flat surface, during the storage of the stratum 10, for example.
  • the height of the projections 20, 21 and 22 in the stacking direction 14 is greater than the height of the projections 16 and 18 in the same stacking direction 14.
  • the height of the projections 20, 21 and 22 in the stacking direction 14 is greater than the height of all the functional projections of the stratum 10 in the same stacking direction 14.
  • the heights of the projections 20, 21 and 22 in the direction of 14 stack are equal.
  • the projections 20, 21 and 22 are advantageously arranged along non-collinear axes so that when the layer 10 is disposed on the flat surface, it is stable.
  • the projections 20, 21 and 22 have the shape of cylindrical studs of circular cross section.
  • the figure 4 illustrates in detail a portion of the stratum 12.
  • This stratum 12 comprises three recesses able to receive, respectively, the projections 20, 21 and 22 when the strata 10 and 12 are stacked.
  • the recesses 26 and 28 receiving the projections 20 and 22 are shown.
  • the recesses 26 and 28, and the projections 20 and 22 have complementary geometric shapes so that when the layers 10 and 12 are stacked and the model 8 is immersed in the refractory material 6, the projections 20 and 22 are not in contact with the refractory material 6.
  • the recesses 26 and 28 have a cylindrical geometric shape with a circular cross section.
  • the recess capable of receiving the projection 21 has the same properties as the recesses 26 and 28.
  • the layer 12 also includes orifices 30 and 32 adapted to receive, respectively, the projections 16 and 18 when the layers 10 and 12 are stacked. In this case and when the model 8 is immersed, the projections 16 and 18 are in contact with the refractory material 6.
  • the orifices 30 and 32 have a generally circular shape. Here, the diameter of these orifices is greater than the diameter of the projections 16 and 18.
  • the geometrical shape of the layers 10 and 12 is determined to form the model 8 when they are stacked.
  • the shape of model 8 can be built digitally using computer-assisted drawing software. Still by numerical construction, the model 8 is divided into strata so as to obtain the shape of the strata 10 and 12.
  • the stratum 10 is made.
  • non-functional projections 20, 21 and 22 are formed.
  • the stratum 10 is made by a non-permanent mold molding process or by machining a polystyrene raw material or by some other method.
  • the stratum 12 is made. During this step 44 recesses adapted to cover the non-functional projections 20, 21 and 22 when the layers 10 and 12 are stacked are formed.
  • the stratum 12 is also made by a non-permanent mold molding process or by machining a polystyrene raw material or by some other method.
  • Stacking the layers involves assembling them in the stacking direction so that the layers are pressed against each other along the bonding seam (s).
  • a glue or an adherent substance is applied to the bonding joint of strata 10 and 12.
  • strata 10 and 12 are centered before being pressed against each other. The centering of the layers 10 and 12 may be assisted by a machine provided for this purpose.
  • models 8 and 9 of the part to be manufactured are made.
  • models 8 and 9 can be made according to the manufacturing method described above.
  • a step 52 the models 8 and 9 are assembled on the connecting bar 13.
  • the connection between the models 8 and the connecting bar 13 is made by interlocking or gluing.
  • the cluster is connected to the power supply system 13A.
  • the cluster is coated with a liquid refractory material.
  • the melting temperature of this refractory material is greater than the melting point of aluminum.
  • the cluster is parboiled so that the refractory coating solidifies to form a shell around the polystyrene.
  • the cluster is arranged in an oven.
  • the assembly formed by the cluster and the funnel is placed in the tank 4.
  • the sand is then poured into the tank 4 so that the cluster is immersed.
  • the tank 4 is vibrated so as to allow the sand to be housed in all the asperities of the outer periphery of the cluster and to compact to form a mold.
  • the tank 4 is for example arranged on a vibrating table.
  • the aluminum is brought to its melting temperature.
  • the aluminum is raised to a temperature higher than the sublimation temperature of the polystyrene but lower than the melting temperature of the shell of refractory material.
  • the aluminum is then poured into the funnel.
  • the liquid aluminum diffuses its heat to the polystyrene thus causing the sublimation of the latter.
  • the temperature of the aluminum being lower than the melting temperature of the shell, the shell remains rigid during casting.
  • the shell prevents the sand from mixing with the aluminum.
  • the shape of the mold is thus unchanged during casting.
  • the polystyrene is removed from the mold and the liquid aluminum takes the place of polystyrene.
  • the casting is prolonged until the volume which was occupied by the polystyrene before the casting is entirely occupied by the aluminum.
  • a step 60 the aluminum is cooled until solidification.
  • a step 62 the aluminum part is released by breaking the mold.
  • the piece obtained is formed of a connecting bar and two aluminum heads.
  • the cylinder heads are then separated from the connecting bar.
  • the stratum 10 is not limited to the case where it comprises three nonfunctional protrusions.
  • Stratum 10 may comprise more than three non-functional projections.
  • the stratum 12 also includes additional recesses able to cover these projections when the strata 10 and 12 are stacked.
  • non-functional projections are not all arranged on the stratum 10.
  • Non-functional projections may be arranged on the stratum 12.
  • the stratum 10 comprises recesses able to receive these non-functional protrusions when the strata 10 and 12 are stacked.
  • the guide pads on the strata 10 or 12 or both so as to facilitate the positioning of the stratum 10 on the stratum 12 during the stacking of these strata.
  • the stratum 10 or the stratum 12 or both comprise recesses able to receive these guide pads when the strata 10 and 12 are stacked.
  • Model 8 is not limited to the case where it comprises two layers. Model 8 may comprise more than two strata.
  • the cluster is not limited to the case where it includes two models. It is conceivable that the cluster comprises a single model 8. It is also conceivable that the cluster comprises more than two models.
