Definitions
- the present invention relates to a method for producing a filter end disk, as required, for example, for a fluid filter in a motor vehicle.
- cylindrical fluid filters are used in which a filter material provided with longitudinal folds is arranged between two filter end disks.
- filters are used for example as a fuel filter or as an air filter in cars or trucks.
- the internal volume of the tool mold into which the first and second plastic molding materials are injected is preferably constant during injection. That is, the mold shape is not changed in its internal geometry during monosandwich injection or co-injection injection. In a two-part tool, for example, the same is opened exclusively for removing the sprayed filter end disk.
- inner core material ie second plastic molding material
- polyamide can be used, for example, which on the one hand is easy and inexpensive to process but on the other hand attracts water or hygroscopic.
- a first water-impermeable plastic molding material such as polypropylene
- the first plastic molding material then encloses, for example, in the manner of a film or skin, the second plastic molding material.
- the tool mold is shaped in such a way that the first plastic mold material penetrates into recesses of the tool mold during injection and fills it in such a way that a sealing element projecting from an end face of the filter end disk results from the solidified first plastic mold material.
- the resulting sealing element is, for example, melted or fused during further processing, and the edge or the fold profile of a cylindrical fold pack is pressed in and connects in a fluid-tight manner after cooling.
- a plurality of concentric, protruding from the Filterendin sealing webs or sealing lips are provided.
- polyamide as a thermoplastic material is suitable as filter end disc material and for injection into a tool mold.
- the first plastic molding material can be chosen such that it has a lower absorption than the second plastic molding material.
- the first plastic molding material preferably further has a lower degree of reflection than the second plastic molding material.
- the first plastic molding material can also have a high Transmittance than the second plastic molding material have. In this case, the absorption, reflection and transmittance each understood with respect to a given radiation.
- the radiation may, for example, radiate heat from an infrared radiator e.g. Laser, filament or light emitting diode array be.
- an infrared radiator e.g. Laser, filament or light emitting diode array be.
- an irradiated heat radiation first penetrates through the outer surface of the filter end disk and then heats a region of the filter end disk below the surface at the interface between the two plastic molding materials. This results in a particularly favorable temperature profile setting, which makes it easier to connect, for example, a filter material with the Filterenduse.
- the second plastic molding material may, for example, be formed from the first plastic molding material by adding carbon black particles for increasing the degree of absorption. This has the advantage, for example, that the rheological properties the plastic molding materials differ insignificantly and processing, for example, in the injection molding machine is particularly easy.
- a filter end disk in particular for a fluid filter of a motor vehicle, which is manufactured according to a monosandwich method or co-injection method claimed.
- a first outer plastic molding material and a second inner plastic molding material is provided, wherein the second plastic molding material is enclosed by the first plastic molding material.
- the first plastic molding material is then impermeable to water and / or water vapor.
- the second plastic molding material may be hygroscopic, such as polyamide, and the first plastic molding material, such as modified polypropylene, may be water impermeable.
- the two plastic molding materials are selected such that they can be processed in particular in a monosandwich process and adhere to one another in the filter end disk.
- the first plastic molding material preferably forms a closed water and / or water vapor-tight outer surface of the filter end disk.
- the invention is also a Filterendusion with a first outer plastic molding material and a second inner plastic molding material, wherein the second plastic molding material is enclosed by the first plastic molding material.
- the enclosure may in this case be complete, in particular if the first plastic molding material is water vapor-tight, or only partially present in alternative embodiments, for example on a flat side of the filter end disk to 50% of the surface, preferably more than 90% of the surface.
- the first plastic molding material may be applied to the filter end disk in a wavelength range, e.g. Infrared, have a lower absorption than the second plastic material.
- the core or second plastic material is then heated more than the outer plastic material surrounding the core.
- the first, outer plastic material may have a lower softening point or melting point than the second, inner plastic material. In either case, by heating the second, inner plastic material, the first, outer, plastic material may be heated to allow connection to a bellows.
- a particularly high heating may occur e.g. be realized at one of the interfaces of the first plastic material with the second plastic material on the side of the second plastic material.
- the present invention comprises a motor vehicle fluid filter with a filter end disc as described in the various embodiments.
- the invention includes an oil or fuel filter with one or more described filter end discs.
- FIG. 3 a diagram for explaining the temperature profile in the case of heat radiation onto a filter end disk
- FIG. 4 shows a sectional view of an injection molding tool for a monosandwich method for producing a filter end disk
- FIG. 5 an illustration of the injection molding tool during an injection process according to a monosandwich method
- Figure 7 a perspective view of a motor vehicle fluid filter
- FIG. 8 a sectional view of a motor vehicle fluid filter
- Figure 9 a cutaway perspective view of a Filterend.
- FIG. 10 shows a sectional view of a further injection molding tool for a monosandwich method for producing a filter end disk.
- FIG. 1 shows process steps for a method for producing a filter end disk.
- FIG. 1 shows a tool mold 1 with a cavity 4, which is enclosed by a cavity wall 5.
- the cavity 4 is filled with heated thermoplastic molding material, such as suitable polyamide, to form the filter end disc.
- an opening 3 is provided in the mold 1, to which an extruder 2 is coupled, in which the plastic mold materials M1 and M2 can be filled.
- the material sequence M1 and M2 can be injected into the mold 1.
- FIG. 1A shows a situation prior to the injection of the two plastic mold materials M1, M2 into the tool mold 1.
- the first plastic mold material M1 which is later to form an outer shell of the filter end disk, is filled into the extruder 2 in such a way that it is the first injection mold passes through the opening 3 in the cavity 4 of the mold 1.
- a second plastic molding material M2 is provided, which likewise has polyamide, for example, which differs from the first material M1 by suitable additives, for example with regard to its radiation absorption properties.
- the materials M1 and M2 are filled in the extruder 2 so that they can be successively pressed into the opening 3 in the mold 1.
- FIG. 1B illustrates the injection process for the first plastic molding material M1, which is introduced into the tool mold 1 in the hot, substantially liquid state. Since at the edges or the surface 5 of the inner wall 5 in the cavity 4 of the mold 1 solidifies the first injected plastic molding material M1, the first plastic molding material M1 is substantially distributed around the inner wall 5. Only then is the second plastic molding material M2 through the opening 3 also injected or pressed into the mold 1.
- FIG. 1B shows the state after which the first plastic molding material M1 has just been completely injected into the tool mold 1 and the second plastic molding material M2 passes through the opening 3. Thus, then the second plastic molding material M2 is also injected through the opening 3 in the mold 1.
- a cavity 6 can be formed, into which the second plastic molding material M2, as shown in FIG. 1C, passes.
- the two plastic mold materials M1, M2 in suitable dosage, are now in the mold 1, wherein the second plastic mold material M2 forms a core of the resulting Filterendusion and the first plastic mold material M1 forms the outer surface.
- these factors can be set that result in a desired distribution of materials in the interior 4 of the mold 1.
- FIG. 2A shows a perspective view of an embodiment of a filter end disk which, for example, is substantially circular with a radius R and a thickness D.
- the filter end disk 7 has two materials, of which a first material M1 forms an outer shell and a second material M2 corresponds to a core of the filter end disk 7.
- the surface O of the filter end disk 7 therefore essentially has only the material M1.
- the material combination can be chosen such that the hygroscopic core M2 is encased by a moisture-shielding shell M1. Since commonly used polyamide is hygroscopic, and therefore absorbs moisture from the air, without the protective cover made of M1 to interfere with further processing steps. In a welding process, which is often necessary to connect the end plate 7 with a filter bellows, it can come in the presence of internal moisture to a blistering, which is undesirable. The water in the end plate component then foams up the liquid molten plastic molding material, and a secure and tight welding is hardly possible.
- the plastic molding materials may also have other functional properties which are important for the further processing and production of filter elements. are part. In particular, it is possible to adjust the heat absorption properties in a targeted manner.
- infrared radiation L is indicated as an arrow, which is irradiated onto the filter end disk 7.
- the arrows A1 illustrate the absorption in the upper material M1 and the arrows A2, which are shown in dashed lines, the absorption of the radiation in the material M2.
- these properties with respect to the irradiation of materials can be expressed by the degree of absorption A, the transmittance T and the reflectance R.
- a + T + R 1, which expresses the interdependence of the different processes in the material.
- FIG. 3 shows a temperature profile along, for example, an axis Ax of the filter end disk 7 shown in FIG. 2 at different irradiation durations of infrared radiation.
- the depth d is illustrated on the X axis and the temperature curve T on the Y axis. Three curves are indicated, the upper curve K1 corresponding to the longest irradiation time and the curves K2 and K3 each having lower irradiation times of the plastic end disk.
- the melting temperature Ts is shown as a dashed line.
- the penetration depth d 0, for example, the surface O of the filter end disk 7 is present.
- the maximum temperature is in each case close to the interface between the two materials M1 and M2.
- the interface can be heated quickly and melted without "burning" the surface.
- the polyamide designated PA6 can be used as a suitable material for filter end discs.
- the outer material region M1 corresponds, for example, to natural-colored polyamide
- the core region with the second plastic molding material M2 is made of polyamide which is dyed black, for example with soot particles.
- Modified Admer QB510E polypropylene would also be suitable as a water-impermeable outer material. This results in a significantly higher absorption of the irradiated radiation by the core material M1, so that a higher temperature develops in the vicinity of the interface than in the surface region.
- the irradiation time can now be set such that at least the material M1 heats up in such a way that the melting point is reached.
- the curve K2 corresponds to a suitable irradiation time.
- the temperature in the first outer material M1 is very homogeneous and decreases only insignificantly in the direction of the second material. This is advantageous because the corresponding filter fleece material is pressed into the molten material layer M1 and only to a small extent into the molten material layer M2 and is intended to form a fluid-tight seal.
- FIG. 4 shows a tool mold 1 with a filler neck 13.
- extruders 2, 9 are provided, wherein the extruder 2, which is arranged horizontally in Figure 4, the main extruder.
- material reservoirs 11, 12 are coupled, which have the respective plastic molding material M2 and M1.
- the main extruder 2 is filled with the second plastic molding material M2, ie the material which causes a greater heat development upon irradiation in terms of heat absorption and Umsetz manufactureenschaften.
- the two extruders 2, 9 also have suitable transport screws 8, 10 or other means to transport the thermoplastic material M1 or M2 in the direction of the respective outlet opening. These are provided with the reference numerals 8 and 10.
- both extruders 2, 9 are each completely filled with the plastic molding material M1, M2.
- the opening of the main extruder 2 is connected to the opening of the secondary extruder 9.
- the first plastic molding material M1 is injected into a front region 20 of the main extruder 2.
- both the material mixture M1 and M2 as well as the sequence for a subsequent injection process results in the tool mold 1.
- the tip of the main extruder 2 is thus filled with the first plastic molding material M1.
- the secondary extruder 9 is separated, and the tip of the main extruder 2 is inserted into the filler neck 13 of the mold. This is shown in more detail in FIG. 4C. It also follows that the two material sequences M1 and M2 are present in the front region of the tip 20 in accordance with their subsequent injection into the mold 1.
- Figure 5 shows in more detail the injection process of the two materials M1 and M2 in the mold.
- FIG. 5B shows the state in which the first plastic molding material M1 is already partially introduced into the tool mold 1 by the punch 8 in the extruder 2. In this case, the material M1 nestles substantially on the surface 5 of the inner wall in the interior 4 of the mold 1.
- the second plastic molding material M2 is also injected into the tool mold 1.
- the second plastic mold material remains essentially in the interior of the resulting filter end disk.
- the flow direction can of course also be done from outside to inside and thus the filtration from the outer jacket of the filter element.
- the respective filter end disk is heated on the side towards the filter material 15 so that a melt of the plastic molding material of the filter end disk 7A, 7B forms on the surface. Subsequently, the edge or the profile of the folded filter fabric is pressed into the melt, which then solidifies. As a rule, this results in good tight transitions.
- the respective end plate can be additionally provided with a sealing element.
- an end plate 7 is provided with integrated seal, the outer material is usually higher quality and more expensive.
- the increased use of lower-grade core material is possible in terms of expense.
- FIG. 10 schematically shows a tool mold 1 suitably configured for the production of the embodiment shown in FIG. 9 for a filter end disk.
- the tool 1A, 1B is in two parts and forms a constant cavity into which the plastic molding materials are injected.
- the second plastic molding material M2 forms the core of the filter end disk and is shown in black. It can be achieved by the design of the recesses particularly thin protruding from the disc sealing webs or sealing structures and thus save material.
- a plurality of concentric recesses are provided to provide many protruding sealing lands.
