Definitions
- the present invention relates to an injection device (for molding micro-parts) consisting of an injection press in which are arranged a mold holder carrying a removable mold in which at least one mold cavity is provided, a counter-mold arranged to exert a molding pressure on the mold. It also relates to a corresponding molding process.
- Patent application EP0272138 discloses a plastic molding process initiated by injection of molten resin into a mold at a high pressure.
- the two parts of the mold movable relative to each other are placed on four clamping bars attached to the four corners of the mold.
- These bars have characteristics of elastic elongation of a delta length L, in order to compensate for a possible lack of parallelism between the two adjacent faces of the mold. Since the mold must be placed in the center of the four bars, the arrangement can only be used for a small number of moldings. Furthermore, the configuration with four bars to be mounted in strictly parallel requires very high accuracy, making the device complex and expensive to implement.
- US7763191 discloses a method and apparatus for performing an injection-compression operation of the stamping type.
- the apparatus comprises a mold enclosing a two-part spacer bar.
- the device is designed to produce a slight axial compression during a high pressure injection.
- Injection-compression molding has the advantages of lower settlement pressure, consistent component quality, lower residual stress and dimensional accuracy compared to conventional injection molding, and is well suited to the fabrication of parts. extremely thin or complex shaped parts, for which conventional injection molding can not meet quality requirements or require very high clamping tonnage.
- the described solution involves controlling the process by means of injection steps with repeated molding cycles performed by making adjustments with calculations between each cycle until the cavity force converges with the force of the cavity. tightening in order to obtain the correct thickness of the molding.
- FR1414485 generally describes the molding of thermoplastic resins, and more particularly a process for rapid molding of various thermoplastic resins from a viscous mass to obtain articles having relatively thin shapes or of which The thickness can vary considerably, without deformation.
- the solution described involves the introduction into the mold cavity of a measured quantity of heated material as a function of the volume of the cavity.
- a micro-piece molding device in which a mold for molding a plurality of parts is housed between a mold holder and a counter-mold, against-mold being crossed by as many injection nozzles that there are parts to inject.
- This type of device gives good results, with pieces of suitable quality when the mold has a small number of cavities, for example a single cavity, double or quadruple.
- the quality of the parts produced becomes random, causing unacceptable proportions of parts to be rejected.
- the invention provides different technical means.
- an injection device for molding micro-parts
- an injection press comprising: a mold holder, carrying a removable mold in which at least one mold cavity is planned; and a counter-mold, arranged to be closed against the mold so as to exert a molding pressure on the mold when the against-mold is closed against the mold, during a molding operation by injection of material into the cavities of the mold.
- the device further comprising a trim compensator adapted to deform under the influence of a force applied unequally on the surface of the mold during the application of the pressure by the counter mold, so as to ensure a substantially uniform distribution of pressure on the surface of the mold.
- the device according to the invention allows for molding in large series with lots comprising several parts, such as 8, 12, 16, 24, 32 pieces or even more, depending on profiles and dimensions.
- the trim compensator comprises a bearing sector abutting against the mold holder and an elastic sector comprising an elastically deformable zone so as to deform under the influence of a force. applied.
- the trim compensator is advantageously formed in one piece, thus facilitating its integration in pre-existing molding facilities, at reasonable costs.
- the elastically deformable zone is dimensioned so as to support at least about 10 to 20% beyond an injection force when the pressure is applied by the counter-mold. and injection of material into the mold cavities.
- the extractor of parts exerts a force of expulsion of the mold parts out of their respective imprint.
- FIG. 2 is a schematic perspective representation of the molding device of Figure 1 in the open position of the mold
- FIG. 3 is a schematic front view of an example of a mold.
- FIG. 1A illustrates an exemplary embodiment in which a mold 10 consists of a molding plate in which a plurality of cavities 11 (or cavities or profiles) to the inverse image of the parts to be produced are formed.
- the plate comprises a single cavity for molding a toothed wheel with pinion.
- a mold support or mold holder 13 in the form of a disk allows the positioning and maintenance of the mold 10 on one of the faces of the mold carrier.
- two retaining bushings 12 visible in FIG. 2) for supporting the mold are provided on either side of the latter to hold it against the mold carrier 13.
- a counter mold 14 is provided in front of the mold 10 and to the mold carrier 13, a counter mold 14 is provided in front of the mold 10 and to the mold carrier 13, a counter mold 14 is provided.
- counter-mold 14 is also in the form of a disk, with a face provided for interfacing with mold 10, in order to form the last wall of fingerprints 11.
- a plurality of nozzles 16, fed by a supply tunnel 17 of material to be injected, allow to make the required input of injection material.
- Figure 3 shows a schematic front view of an example of mold 10 comprising four cavities January 1 representing a gear form.
- An example of a part (a wheel with a pinion) 1 1 1 manufactured by the injection device of the invention is shown in Figure 3. It goes without saying that the shape of the
- fingerprints 1 1 can take any other form corresponding to the part to be produced, for example a microlens.
- Figure 4 shows a perspective view of a mold carcass 100 comprising a receiving plate 130 having a plurality of cavities 131 (eight in the example of Figure 4). Each of the cavities 131 is configured to receive a mold holder 13 and to pre-position it with respect to the counter-mold 14.
- the mold carcass 100 also comprises a counter-mold plate 140 in which the counter-mold 14 is housed. (or counter-molds 14).
- the counter-mold plate 140 may further comprise injection channels 160, distributing the material to be injected through the tunnel
- the device is intended for molding micro-parts, the dimensions of the various components are provided with a high level of accuracy. It is the same for the elements of the chamber 40 of molding which must allow to position, or center, the mold 10, the cavities and counter-mold 14 very accurately.
- the centering accuracy of one part of the mold with the other is made by the centering pins 1 5.
- the two sockets 12 held with screws are slightly longer than the thickness of the mold holder 13. Leaving a game radial between the outer diameter of the collar retaining sleeve 12 and the bore of the mold carrier 13, the latter will be centered in XY by the two pins 1 5. This requires more high alignment accuracy between the bores of the cavities 131 of the receiving plate 130. centering is independent of the number of fingerprints 1 1 because each is centered individually.
- the trim compensator 20 is an elastically deformable element, allowing, thanks to its deformations, to maintain optimal alignment of the mold elements.
- the deformations of trim trim 20 are due to its architecture and materials constituting it. In the embodiment illustrated in the figures, the
- trim compensator 20 comprises three sectors: a bearing sector 21 against the mold carrier 13; an elastic sector 23, opposite the support sector 21; and a junction sector 22, forming a circumferential clearance between the other two sectors 21 and 23.
- the junction sector 22 has a diameter smaller than the diameters of the two adjacent sectors, thus forming a free zone between these two sectors.
- the elastic sector 23 further comprises an elastically deformable zone 24, extending circumferentially on the elastic sector 23. This zone is dimensioned so as to allow the trim compensator 20 to react to pressure variations on the surface of the mold 10, to compensate for them by deforming at the elastically deformable zone 24. After molding, when the pressure is no longer exerted and mold 10 is disassembled, the trim compensator 20 returns to its original shape thanks to its elastic properties .
- the elastically deformable zone 24 of the trim compensator 20 is free and a rigid extra thickness 231 in the zone 23 abuts on a support plate 120 included in the mold carcass 100.
- the molding chamber 40 also houses a puller 30 of molded parts facilitating the extraction of molded parts of the mold, after each of the molding phases.
- the extractor 30 comprises four extraction rods 31, the end 32 pushing the moldings is visible in Figure 3.
- the extractor 30 can abut against a plate of extractor pusher 300 of the mold carcass 100.
- a demolding strip 50 may be advantageously used to facilitate the extraction of molded parts after molding.
- a strip having non-stick properties for example a PTFE-based tape (Teflon), is preferably used.
- the molding chamber 40 comprises a first half 41 comprising the counter mold 14 and the nozzle or nozzles 16, and a second half 42 comprising the mold 10, the mold holder 13 and the extractor 30.
- the parts of the device in particular the mold 10 provided with its multiple moldings 1 1
- the mold is closed by placing the two halves 41, 42 of the speakers against each other as shown in Figure 1a.
- the against-mold 14 has a centering action with the mold 10 (as discussed above) and creates a strength of pressure acting against the mold 10.
- the trim compensator 20 provides alignment, particularly axial , elements, in particular of the mold 10 with the counter-mold 13. This alignment ensures a substantially uniform distribution of the pressure on the molding surface, allowing the production of parts under favorable conditions in order to reach levels significantly higher production levels.
- the trim compensator 20 makes it possible to keep the adjacent faces of the mold carrier 13 and against the mold 14 well parallel to each other, so that the pressure exerted on the mold is uniform over the entire surface of this mold. latest.
- the trim plate is deformed so as to absorb the overpressure, thereby restoring a uniform pressure on the entire surface of the mold.
- Maintaining this uniform pressure over the entire mold surface optimizes the conditions in which are performed the injection and molding of the multiple parts.
- the calculation of the pressure force acting against the mold 10 can be achieved according to the formula of a beam embedded at both ends, of trapezoidal shape with the geometric development of the outer and inner diameters of the elastic zone for the sides; the difference of the rays for the length, and the thickness of the zone elastically
- the dimensioning of the elastically deformable zone 24 is made in such a way that the latter supports at least about 10 to 20% beyond an injection pressure once the surface of the part (ie say at least about 10 to 20% beyond an injection force), during the application of the pressure by the counter-mold 14 and the injection of material into the impressions 1 1 of the mold 10.
- the force necessary to compress the elastically deformable zone 24, as well as the additional force (10 to 20% beyond an injection force) are taken by the closing force of the press.
- the trim compensator 20 can be deformed and allows the adaptation of the mold 10 to variations in thickness of the demolding strip 50, or any other insert. Indeed, the variations in thickness will be taken up by the flexibility of the elastically deformable zone 24.
- the demolding strip 50 makes it easier to demold the parts produced.
- An extractor 30 is advantageously used to exert a force towards the free face of the molded parts, so as to extract them from the mold.
- a demolding strip 50 facilitates the extraction of the molded parts by reducing the risk of sticking and by producing an additional extraction force. Between each molding, the strip 50 is moved so as to present for molding a zone of new material, not deformed, or altered by the molding previously performed.
- the injection device described here allows to inject various polymeric materials.
- the device lends itself well to the injection of technical materials such as polyoxymethylene (POM),
- polystyrene resin poly(phenylene sulfide) (PPS), liquid crystal polymer (LPC), polyimide (PI), polyamide (PA, PA6), these materials can be highly loaded with fiberglass or mineral fillers.
- PPS poly(phenylene sulfide)
- LPC liquid crystal polymer
- PI polyimide
- PA polyamide
- various other materials suitable for injection can be used in the injection device of the invention with the trim compensator 20.
- a constraint may come from the materials used for the impressions 1 1 which are subject to the invention. abrasion and / or corrosion related to the converted polymer.
- the injection device of the invention allows to mold different types of micro-parts, including wheels and sprockets, housings, turntables (watches), optical components for a portable device such as a phone portable, microswitches, inserts, etc.
