Definitions
- the invention relates to a method for producing an article from at least one independent part and a fixing part, wherein the independent part is movably positioned to the fixing part. If at least two independent parts are present, they are mutually movably connected to each other in the fixing part.
- both components are used at low processing temperatures or the component for the first injection-molded part can be exposed to high service temperatures in the short term.
- the loose bond arises when the usual thermal shrinkage for plastics occurs.
- This method is not suitable for producing a loose composite of ceramic molding compounds or metals, since the incompatibility of the plastics is a prerequisite for this method, which also includes no heat treatment.
- DE 196 52 223 C2 discloses structured moldings of at least two different materials which are joined together in a composite material. Furthermore, there is the setting of a span- low-expansion joint zone described by suitable material composition or different particle content in partial volumes of the materials. For example, pure binder is used to produce hollow bodies. A production of movable components is not disclosed.
- this method should allow the production of an article of metallic, glassy or ceramic components by means of injection or hot casting in a single operation to reduce handling and adjustment technique after molding the parts of the article or avoid.
- the inventive method for producing an article comprises the steps a) to e). First, a tool is provided according to step a), each having a cavity for receiving one of the parts to be molded.
- the tool further has a parting plane which divides the tool into two mold halves.
- Decisive here is the arrangement of the cavities with respect to this parting plane:
- the cavities are, with respect to the parting plane, adjacent to each other alternately above or below the parting plane arranged so that they lie alternately in one of the two mold halves, the cavities remain separated.
- the at least one cavity is filled with a hardenable or solidifying molding compound comprising a sintered material. After the solidification of the molding material, the parts to be formed are formed in the cavities.
- the material for injection or hot casting from at least one injection unit via at least one channel at the same time or in succession introduced into the cavities.
- Particularly suitable for this purpose are two- or multi-component injection molding.
- each formed part is removed from its cavity.
- the tool already has a fixing part for receiving the parts to be formed.
- the article is already formed during step b) or c) and the subsequent step d) is omitted.
- the parts are after their demolding according to step d) in a fixing or preferably in a cavity, by filling the fixing part is molded, introduced.
- the demolded parts are for this purpose mounted on the fixing part or joined thereto.
- the total number of parts removed from the mold is transferred into at least one further cavity which is likewise present in the mold, by the filling of which the fixing part is shaped.
- the transfer of the parts from the cavities, in which their shaping took place, into the further cavity preferably takes place by means of guide elements, which after the transfer can remain wholly or partly in the at least one further cavity.
- guide elements At those points where the guide elements are removed from the mold, there is an extension of the further cavity, through the filling of which an additional connection is created between at least one part and the fixing part.
- the guide elements or parts thereof can serve as an ejector in terms of a simpler handling technique.
- step e) the still unfinished article, which can be referred to as a green compact, is subjected to a heat treatment, in particular debindering with subsequent sintering.
- various molding materials which are called Feedstocks and consist of a binder and a powder of the desired material, so injected into the tool that they can touch each other.
- the parts can also be injection molded from the same feedstock.
- the binder In order to convert the molding compositions into a metal, glass or ceramic part, the binder must be removed on the basis of water, oligomers, polymers or mixed systems after molding and the powder sintered to form a generally dense material, with shrinkage taking place.
- This shrinkage leads to the reduction of the article compared to the at least one injection-molded part, which is also called green body.
- the materials In order for the article, which may be composed of different components, to be sintered, the materials must have similar sintering temperatures, or a component that sinters earlier may shrink from the design of the gearbox earlier than the one that sinters at a higher temperature. Due to the differences in the sintering shrinkage of the materials used for the parts and the fixing parts distance and clearance between the parts are set with each other and between the parts and the fixing part. In vi 'elen cases, it is advantageous if the fastening parts shrink more than the movable parts.
- the sintering shrinkage for sintered materials generally ranges between 10% and 25%, while the thermal shrinkage in plastics is at most 3%.
- the parts are made of metal, an alloy, a (mixed) ceramic or glass.
- Particularly preferred for the moving parts in gears (gears) or joints is hardened steel (preferably 17-4PH) or a tough ceramic, especially zirconia.
- the fixing member As materials for the fixing member, hard metals (e.g., tungsten carbide-cobalt), hardened metals, hard ceramics (particularly, alumina), silicon nitride or silicon carbide are preferably used.
- the fixing part need not necessarily be made of a sintered material. In this case, however, it is advantageous if the fixing part is already inserted directly into the tool.
- the present invention has as a significant advantage that parts and fixing parts can consist of wear-resistant and / or high-strength materials. Furthermore, the parts do not have to be mounted after shaping and sintering. Especially in microdimensions, the handling and adjustment of parts is very cost-intensive due to the required precision.
- the mounting of Grünlin This makes it even more difficult for the feedstocks to be a material of low strength due to the binder and the high degree of powder filling.
- the method according to the invention is suitable for use in microsystem technology, powder injection molding, two-component powder injection molding, in gear technology (for planetary gears, ball joints, bearings, linear guides, etc.) and in manufacturing technology for gearbox construction.
- the method according to the invention makes it possible to mutually pair the moving parts of the transmission already during the shaping process and to install them in a housing for mounting the moving parts.
- Fig. Ia cross section
- FIG. 1b top view at different levels on the cavities
- the tool shown schematically in Fig. Ia is used, the three cavities for three gears to be produced 11, 11 ', 12, which, as can be seen in Fig. Ib, are arranged separately adjacent to each other axially offset.
- the tool further has a parting plane which divides the tool into two mold halves 1, 2, in the ejector-side mold half 1 and in the nozzle-side mold half 2.
- the outer two cavities for the gears 11, 11 'on a first level in the ejector-side mold half 1 and the central cavity for the gear 12 are arranged on a second plane, which is located above the first plane in the nozzle-side mold half 2.
- the ejectors may be stepped, i. be provided with an ejector 4, 4 ', so that an end-side force application of the ejector sleeve on the gear supports the demolding of the ejector.
- the tool jaws 6 have in the region of the hubs of the outer gears 11, 11 'on a cavity 13 for the fixing part.
- An embodiment of the central ejector 3, in which it is not round, but oval or edged in the region in which it is inserted in the hub of the gearwheel 12, is advantageous, so that after the heat treatment, a drive axle is positively inserted into the middle gearwheel 12 can be.
- the tool jaws 6, which enclose all three gears 11, 11 ', 12, are above and below the third plane, in which ⁇ now the gears 11, 11', 12 lie, respectively on the gears 11, 11 ', 12 facing away Side with a second feedstock containing alumina powder, overmoulded.
- the injection point can be positioned as desired, however, an injection point in the position 21 is advantageous.
- the second feedstock fills the cavities in the tool jaws 6 and the volume of the cavities in the outer gears 11, 11 'exposed by the withdrawn ejectors 5, 5'. , whereby their axes are formed. In the area of the hubs of the gears from the first feedstock, the second feedstock touches the first feedstock without mixing the two feedstocks.
- An advantageous embodiment of the tool jaws 6 is that the tool jaws 6 are double-walled.
- the second feedstock thus also forms a fixing part 14 for the transmission.
- the fixing part 14 can later be used as a serve housing of the transmission.
- both feedstocks sinter at the same sintering temperature with a sintering shrinkage which is either the same for the parts 11, 11 ', 12 and the fixing part 14 or assumes slightly greater values for the fixing part 14.
- zirconium dioxide parts adhere to the aluminum oxide parts, they change to a soluble compound during the first movement of the gearbox.
- the second embodiment is a variant of the first embodiment, wherein the gear of FIG. 6 is produced in three-component injection molding.
- the shape of the gears 11,11 ', 12. Also serving simultaneously as a housing fixing member 14 is formed in the same way.
- the third feedstock like the second feedstock, contains aluminum oxide powder, but with a powder filling ratio and / or a powder particle size distribution which permits greater shrinkage during sintering than in the first or second feedstock.
- the length of the axes is dimensioned by the shape of the tool so that it fits the sintering shrinkage.
- the second feedstock can have the same or a slightly lower sintering shrinkage compared to the first feedstock. With the difference in sintering shrinkage distance and clearance between the gears and the fixing part are adjusted.
- the tool is advantageous to equip the tool as a three-plate tool with turntable on the ejector-side mold half 1.
- the ejector-side mold half 1 rotates the gears 11, 11 ', 12 by means of the turntable in the direction of the tool jaws 6, which may be mounted on the nozzle side, on the ejector-side mold half 1, the nozzle-side mold half 2 or outside of the tool.
- a special configuration of the tool makes it possible to form the next toothed wheels during the shaping of the fixing part 14 (housing) or the axes in the cavities of the tooth geometry, which are advantageously arranged on the nozzle-side mold half 2.
- the thickness of the tool jaws 6 and the sintering shrinkage as well as the difference of the sintering shrinkage between the first and the second feedstock define the gap.
- small pyramidal or conical micro-elevations can be formed on the gears or the housings in the region of the hubs or the end faces of the gears. Even if it comes in the area of the tips of the pyramids or cones for sintering of gears and housing, such. B. when using different Steels, by applying a torque between the gears and the housing in the state of the green body or preferably in the sintered state, this compound can be easily broken by their smallness.
