Definitions
- the invention proposes an arrangement for forming a two-part part comprising a core and an outer body made of a metal or ceramic powder-based polymer material partially covering the ceramic core.
- the invention provides a mold for resisting injection constraints, while not damaging the core which is fragile.
- Powder injection molding commonly known as Powder Injection Molding (PIM) in English, makes it possible to produce complex-shaped ceramic or metal components using tooling which is used in the field of molding plastics.
- PIM Powder Injection Molding
- Such a powder injection molding process comprises a first step consisting in producing a so-called “master” mixture, commonly called “feedstock”, which consists of a mixture of an organic material forming a polymeric binder and an inorganic powder. ceramic or metallic.
- feedstock consists of a mixture of an organic material forming a polymeric binder and an inorganic powder. ceramic or metallic.
- the proportion of inorganic powder in the feedstock is between 40% and 70% by volume.
- a second step of the powder injection molding process consists of making the part (s) by injection of the feedstock, using conventional tools of the plastics industry.
- the organic binder is removed and the resulting part is sintered.
- the production of a part made of two different materials using such a molding process consists of producing a first part, or core, of a first material, for example ceramic, and then forming the external body of this part by injection molding of the feedstock containing the powder.
- a certain pressure is applied between the core and the mold to maintain a good contact of the respective faces of the core and the mold.
- the ceramic core is manufactured with certain dimensional tolerances. This requires to be careful not to cause breakage of the core when closing the mold because the pressure applied to the core could cause the breakage of it.
- Document No. FR 2,485,987 describes a mold made of elastomeric material.
- Such a mold makes it possible to compensate for the dimensional variations of the core without the risk of breaking it.
- the elastomer material deforms and the contact between the mold walls and the ceramic core is broken, so that part of the feedstock can be removed. infiltrate between the core and the mold, covering a face to remain uncovered, or forming burrs.
- the powder contained in the feedstock is particularly abrasive, which can deteriorate the walls of the mold and thus cause defects on the component obtained.
- the document FR.2.707.205 describes a mold of which only a part covering the core is made of synthetic material.
- the invention relates to an arrangement for the overmolding by injection of a mixture based on metal and / or inorganic powder around a core comprising an upper horizontal face and a lower horizontal face, which comprises a mold delimiting a cavity in which the core is received, so that the upper face of the core is supported upwardly against an upper face vis-à-vis the cavity and the lower face of the core is supported downward against a lower face vis-à-vis the with respect to the cavity,
- the elastically deformable portion comprises a resiliently deformable metal blade on at least one face of which the core is directly in abutment.
- the production of the elastically deformable portion from a metal plate allows this deformable portion to resist abrasion and pressure from the feedstock injection, while adapting the dimensions of the cavity to the dimensions of the ceramic core.
- the elastically deformable portion comprises a plastic plate which is compressed between the metal blade and a rigid part of the mold.
- the mold comprises a hollow housing open towards the cavity, which receives the elastically deformable portion such that the metal blade is located at a distance from the bottom of the hollow housing.
- the plastic plate is arranged between the metal blade and the bottom of the hollow housing.
- the metal blade is arranged at the opening of the hollow housing.
- the metal blade is made of spring steel.
- the plastic plate is compressed between the metal blade and the bottom of the hollow housing.
- the plastic plate is made of polytetrafluoroethylene (PTFE).
- PTFE polytetrafluoroethylene
- the plastic plate is made of polytetrafluoroethylene (PTFE) loaded with 15% graphite.
- PTFE polytetrafluoroethylene
- the elastically deformable portion is removably mounted in the hollow housing.
- Figure 1 is a schematic perspective view of a part made with an arrangement according to the invention
- Figure 2 is a schematic perspective view of an exploded arrangement according to the invention.
- Figure 3 is an exploded view in axial section of the arrangement shown in Figure 1;
- FIG. 4 is a section similar to that of FIG. 3, showing the dimensional differences between the cavity of the mold and the ceramic core;
- Figure 5 is a view similar to that of Figures 3 and 4, wherein the mold is closed and the deformable portion of the mold is deformed.
- FIG. 1 a part 10 made in two parts which comprises a central core 12 ceramic and an outer body 14 metal.
- the outer body 14 is made from a powder mixture of inorganic material, that is to say for example a metal or ceramic powder, combined with an organic binder. Subsequently, we will use the common name "feedstock" to designate this mixture.
- the feedstock is made from a metal powder consisting of spherical beads with a diameter of less than 45 ⁇ and the binder is a mixture based on polyethylene or paraffin and stearic acid.
- the outer body 14 is made by overmolding the feedstock around the central core 12 and the binder of the feedstock is removed and the piece 10 is then sintered.
- the core 12 is here of generally cylindrical shape of main axis A vertical. It is produced conventionally or in a powder injection molding process. As a result, dimensional variations, particularly concerning its axial length, are envisaged.
- the outer body 14 is made by overmolding the feedstock around the core 12 so that the upper end horizontal face 12a and the lower end horizontal face 12b of the core 12 are not covered by the feedstock.
- FIGS. 2 and following show an arrangement for producing the outer body 14 of the part 10 by overmolding the feedstock around the core 12.
- This arrangement is intended to be mounted in a metal casing of a conventional injection molding machine.
- the arrangement mainly comprises a mold 18, which may also consist of a mold part or a frame, which consists of a first fixed lower part 20 and movable upper part 22.
- the fixed part 20 and the mobile part 22 delimit a cavity 24 in which the core 12 is arranged and in which the feedstock is intended to be injected to form the outer body 14 of the part 10.
- the fixed portion 20 and the movable portion 22 of the mold 18 further comprise fingers 26 for their positioning relative to each other, and means 28, consisting here of a screw system, for exerting a clamping force two parts 20, 22 of the mold 18 against each other, to resist the injection pressure.
- the dimensions of the two parts 20, 22 of the mold are relatively large compared to the dimensions of the cavity 24 and the part 10 to made because the deformation of the two parts 20, 22 of the mold 18 must be the lowest possible during the injection feedstock.
- the core 12 is inserted into the cavity 24 before the closure of the mold 18.
- the upper face 12a of the core 12 When the core 12 is in position in the cavity 24, the upper face 12a of the core 12 is in abutment against an upper face 24s of the cavity 24 and the lower face 12b of the core 12 bears downwards against a lower face 24i of the cavity 24.
- the axial length of the core may be larger or smaller than a nominal dimension.
- the distance between the upper face 24s and the lower face 24i of the cavity 24, when the mold 18 is closed, is defined so that whatever the axial length of the core 12, the upper faces 12a and 12b of the lower core 12 are always bearing against the upper 24s and lower faces 24i of the cavity 24.
- this distance between the upper 24s and lower 24i of the cavity 24, is always less than or equal to the axial length of the core 12. This ensures that the feedstock can not cover the upper faces 12a and 12b of the core 12.
- the core 12 is ceramic and may break if the clamping force of the two parts 20, 22 of the mold 18 is applied to the core 12.
- the mold 18 comprises a portion 30 which is deformable elastically and which is able to deform when the mold 18 is closed to compensate for the difference between the length of the core 12 and the distance between the upper faces 24s and lower 24i of the cavity 24.
- the deformable portion 30 is arranged in a hollow housing 32 formed in the fixed portion 20 of the mold 18 so that an upper face of the deformable portion 30 delimits at least part of the lower face 24i of the cavity 24.
- the upper face of the deformable portion 30 is flush with the upper face 20s of the fixed portion 20 of the mold 18.
- the hollow housing 32 is of complementary shape to the shape of the deformable portion 30.
- the axial compression force of the core 12 between the upper portion 22 of the mold and the deformable portion 30, resulting from the elastic deformation of the deformable portion 30, is large enough to prevent the feedstock from infiltrating between the upper faces 12a and 12b of the lower core 12 and the faces 24s, 24i vis-à-vis the cavity 24 , respectively, as well as between the lower face 22i of the upper part 22 of the mold 18 and the upper face 24s of the deformable part 30.
- the deformable portion 30 comprises a metal blade 34 which is elastically deformable, of which an upper face forms at least part of the lower face 24i of the cavity 24.
- the upper face of the metal blade 34 completely forms the lower face 24i of the cavity 24.
- the core 12 is directly downwardly supported on the upper horizontal face of the blade 34 and causes an elastic deformation towards the bottom of the blade during the closure of the mold 18, to compensate for the difference in values between the height of the core 12 and the distance between the faces 24s, 24i vis-à-vis the cavity 24.
- the blade 34 In return for this elastic deformation, the blade 34 produces on the core 12 an elastic force corresponding to its deformation.
- the blade 34 is made of spring steel of the type known under the name X10.
- the hardness of such a metal is particularly advantageous in the present case of the injection of the mixture based on metal powder.
- the powder forming the feedstock is particularly abrasive, and such a constituent metal of the blade 34 is sufficiently resistant to abrasion so that the blade 34 is not damaged during the injection of the feedstock.
- this constituent metal of the blade 34 limits the deformations resulting from the injection pressure.
- the deformable portion also comprises a plastic plate 36 which is compressed between the metal blade 34 and the bottom of the hollow housing 32 receiving the deformable portion 30.
- the plastic plate 36 functions as a damper to the deformation of the blade 34, it deforms elastically by compression during the closure of the mold 18 and produces an elastic force on the metal plate 34 which is transmitted to the core 12.
- the elasticity of the plastic plate 36 is determined in such a way that regardless of the dimensions of the core 12, the elastic force produced by the plastic plate 36, combined with the force produced by the blade 34 after the closure of the mold 18 , is large enough to prevent any feedstock infiltration on the upper faces 12a and 12b of the lower core 12, and so that this elastic force is less than a force likely to cause the breakage of the core 12 by compression.
- the plastic plate 36 makes it possible to limit the extent of the deformation of the blade 34 in an area centered on the core contact surface 12 on the upper face of the blade 34.
- the peripheral body 14 formed will comprise a slight excess thickness located at the lower end 12b of the core 12.
- the deformable portion 30 of the mold consists solely of a metal blade 34.
- An empty space is maintained between the blade 34 and the bottom of the hollow housing 32, for example by means of shims to allow the blade 34 to deform elastically downwards in the hollow housing 32.
- the dimensions of the blade 34 are then determined so as to produce an elastic force on the core 12 which prevents the feedstock from covering the faces of the core 12 and which does not cause the core 12 to break.
- the blade 34 is resistant to the abrasion of the metal powder, it can be damaged as the mold 18 is used.
- the blade 34 and possibly the plastic plate 36, is adapted to be removed from the hollow housing 32 to be replaced by a new blade 34, or a new plastic plate 36, respectively.
- the blade 34 and the plastic plate 36 are not fixed in the hollow housing 32, their holding in position is performed on the one hand by the movable part 22 of the mold and on the other hand by the pressure d injection of the feedstock.
- the blade 34 is made of X10 CrNil8-8 spring steel, its HV hardness is between 170 and 250, its Young's modulus is 195 GPA and the tensile strength limit (Rm ) is 690 to 900 MPa.
- the plastic plate 36 is in a first example made of unfilled polytetrafluoroethylene (PTFE), its Shore D hardness is 50 to 65, its Rockwell hardness is 25, its Young's modulus is 300 to 800 MPa, its resistance to tensile strength: 10 to 40 MPa, its elongation at break is between 100 and 400%.
- the plastic plate 36 is PTFE loaded with 15% graphite. Its Shore D hardness is greater than 55, its density 2.14 to 2.19 g / cm3 and its elongation at break is greater than 200%.
