Definitions

  • the invention relates to a hot runner nozzle for injection molding tools with a nozzle body having a passage channel for a melt, the nozzle body comprising a feed opening at a first end region and an outlet opening at a second end region.
  • a temperature gradient occurs on the nozzle body when the hot runner nozzle is heated using a suitable heating element. There is a higher temperature in the central region of the nozzle body than in either of the end regions of the nozzle body. The reason for this is that the hot runner nozzle attached to a mold of the injection molding tool makes contact with the relatively cool mold at its one end region. This is necessary for sealing reasons and for stability.
  • the contact surface between the nozzle body and the mold is located on an insulating ring that is permanently connected to the nozzle body.
  • the object is to create a hot runner nozzle of the type mentioned above that permits as uniform a temperature level as possible over its nozzle length when heated in the melting position.
  • the nozzle body has at least one cavity in addition to the passage channel and a guide channel, provided, if applicable, for a closing needle.
  • the heat flow in the nozzle body can be set so that during use of the hot runner nozzle a largely uniform temperature level results over the longitudinal direction of the nozzle body.
  • the partial region of the nozzle body surrounding the cavity can be designed as a single piece, leaks, such as those that may occur at joints, can be avoided from the outset in the region of the cavity.
  • the at least one cavity can be produced using a generative manufacturing process, in particular using selective laser sintering.
  • the nozzle body is created in layers in that one thin layer of a powder material is applied each time over the entire area in a number of operations, for example, using a spreading knife on an appropriate base.
  • a laser beam is positioned to sinter the powder at each processing location corresponding to those points where the nozzle body is to be created.
  • the energy supplied by the laser is absorbed by the powder and results in a localized sintering or melting of particles at the processing location.
  • the structure obtained in this manner is lowered by the thickness of the layer to apply and to structure another layer in the same manner.
  • the process steps described above are repeated until the nozzle body is finished.
  • the cavity is evacuated or filled with a medium that has a thermal conductivity different from the material of the wall of the nozzle body adjacent to the cavity. If the cavity is evacuated, the cavity provides a particularly high thermal insulation.
  • the cavity may also contain a gas, such as air, however, to achieve high thermal insulation.
  • the medium is a metal having a higher thermal conductivity than the material of the wall of the nozzle body adjacent to the cavity.
  • the metal may contain, in particular, copper and/or aluminum. These metals have high thermal conductivity but are available at a relatively affordable cost and are workable.
  • the metal or the medium is filled into the cavity when fabricating the hot runner nozzle preferably by way of a fill opening provided in the wall of the cavity. If needed, the cavity may have a vent opening in addition to the fill opening. The fill opening and, if applicable, the vent opening are plugged after filling the cavity. In the case of a solid medium, the fill and/or vent opening is preferably plugged by means of the medium itself.
  • the cavity runs in the form of a ring around the passage channel. In this way, a very uniform temperature level of the nozzle body is provided around the circumference.
  • the nozzle body has at least one contact surface that can be connected to a mating surface of an injection molding tool, if the nozzle body has at least one first cavity adjacent to the contact surface and at least one second cavity that is spaced farther from the at least one contact surface than the first cavity,
  • This measure provides a particularly uniform temperature level all along the nozzle body.
  • the nozzle body has a nozzle tube surrounding the passage channel wherein the nozzle tube is connected with at least one nozzle body part having the contact surface, this part consisting of a material having a lower thermal conductivity than the material of the nozzle tube and wherein the at least one first cavity is located in the at least one nozzle body part and the at least one second cavity is located in the nozzle tube.
  • Different powder materials may also be used to fabricate the different partial regions of the nozzle body in a generative process. In this way, the thermal flow during operation of the hot runner nozzle from the nozzle body into the mold of the injection molding tool is reduced particularly effectively such that an even more uniform temperature level results along the longitudinal direction of the nozzle body.
  • the nozzle tube preferably consists of metal and the nozzle body part of ceramic.
  • the nozzle body has a preferably one-piece nozzle tube surrounding the passage channel wherein the nozzle tube has at least two cavities that are spaced apart in the longitudinal direction of the passage channel and wherein a section of the nozzle tube that does not have any cavities is located in the longitudinal direction between said cavities.
  • the nozzle body may have at least two cavities that are connected to one another by way of at least one connecting channel that has a smaller cross-section than the cavities. In this way, a plurality of cavities can be filled at the same time with the first medium and/or the second medium in a simple manner during fabrication of the nozzle body.
  • the at least one cavity or one section extends in the shape of a spiral or coil around the longitudinal central axis of the hot runner nozzle.
  • the nozzle body has a base body onto which one partial region is applied in layers by means of a generative method, this region having the at least one cavity.
  • the base body may, in this respect, consist of a high-strength material having the required resistance to pressure, temperature and wear.
  • the base body can be fabricated using a conventional manufacturing method.
  • the worn partial region of the needle guide can be removed, for example, by grinding off the hot runner nozzle and then, using the generative manufacturing method, reapplied on the remaining part of the hot runner nozzle.
  • FIGURE shows a longitudinal section through a hot runner nozzle.
  • a complete hot runner nozzle for an injection molding tool has a nozzle body that has one passage channel 2 for a melt.
  • the passage channel 2 has one feed opening 4 at a first end region 3 facing the injection molding tool when in the position of use and an outlet opening 6 for the melt at a second end region 5 at some distance from this.
  • the hot runner nozzle 1 is broadened at its first end region 3 forming a head similar to that of a screw.
  • the first end region 3 has a roughly disk-shaped nozzle carrier 7 on whose rear surface facing away from the outlet opening 6 are located the feed opening 4 and a first needle guide 8 surrounding a guide channel 9 for a closing needle, not shown in more detail in the drawing, that engages in the passage channel 2 .
  • the first needle guide 8 is made of a material that is more resistant to wear than the material of a partial region of the nozzle carrier 7 bordering the first needle guide 8 .
  • the feed opening 4 is offset perpendicular to the longitudinal direction of the hot runner nozzle 1 with respect to the needle guide 8 and the passage channel 2 has a channel section in the nozzle carrier 7 that runs perpendicular to the longitudinal direction of the hot runner nozzle 1 , said section connecting with the feed opening 4 with another channel section running along the longitudinal axis of the hot runner nozzle 1 to the outlet opening 6 .
  • the first end region has a nozzle seat 10 that is also roughly disk shaped and connected over a flat area with the nozzle carrier 7 , the hot runner nozzle 1 making contact with the injection molding tool at this seat.
  • the nozzle seat 10 is bonded with the nozzle carrier and is made of a material having a lower thermal conductivity than the material of the nozzle carrier 7 .
  • the nozzle carrier 7 may, for example, be made of metal and the nozzle seat 10 made of ceramic.
  • the nozzle seat 10 is bonded with a nozzle tube 11 that is arranged roughly concentrically with the passage channel 2 and runs in the longitudinal direction of the hot runner nozzle 1 .
  • the nozzle tube 11 preferably consists of metal, in particular of steel. To thermally decouple the nozzle tube 11 from the injection molding tool, an air gap is provided between the outer shell of the nozzle tube 11 and the injection molding tool.
  • the nozzle tube 11 has a nozzle section 12 on the end spaced away from the nozzle seat 10 , this section being connected to the other nozzle tube 11 as a single piece.
  • the nozzle section 12 has, at its free end, the outlet opening 6 and the section tapers conically toward the outlet opening 6 .
  • the nozzle section 12 has a second needle guide 14 located in a straight line extension of the first needle guide 8 and made of a material that is resistant to wear.
  • the hot runner nozzle 1 Adjacent to the nozzle section 12 , the hot runner nozzle 1 has a ring-shaped shoulder at its second end region, this shoulder forming a recess holding an insulating ring 13 .
  • the hot runner nozzle 1 makes contact with a support point of the injection molding tool on the insulating ring 13 .
  • the nozzle body has a plurality of first cavities 15 A and a plurality of second cavities 15 B.
  • the first cavities 15 A are filled with air and the second cavities 15 B with a metal having a higher thermal conductivity than the material of the nozzle-body walls bordering the cavities 15 A, 15 B involved.
  • the metal may be copper, in particular.
  • the walls bordering each of the individual cavities 15 A, 15 B are connected to one another as a single piece. In this way, joints where melts may leak from the nozzle body are avoided on the cavities 15 A, 15 B.
  • the cavities 15 A, 15 B are each of a ring shape and surround the passage channel 2 without interruption.
  • a first cavity 15 A is provided that serves to reduce the thermal loss from the nozzle body into the injection molding tool and/or the interior cavity of the injection molding tool.
  • Second cavities 15 B are provided in the nozzle tube 11 .
  • Second cavities 15 B that are adjacent to one another are spaced apart by nozzle tube sections, which have no cavities 15 A, 15 B, in the longitudinal direction of the nozzle tube 11 marked by the double arrow.
  • the second cavities 15 B are located roughly in the center between the inner and outer shells of the nozzle tube 11 . With the exception of any fill openings provided on the cavities 15 B, the second cavities 15 B of the nozzle tube 11 are spaced apart from the outer shell and the inner shell of the nozzle tube 11 .
  • the thermal conductivity of the nozzle tube 11 is increased by the second cavities 15 B so that, while operating the hot runner nozzle 1 , a largely uniform temperature level is reached along the nozzle tube 11 . Temperature differences that may occur along the length of the nozzle tube 11 cause a thermal flow in nozzle tube 11 that reduces the temperature difference.
  • a second cavity 15 B that surrounds the passage channel 2 in the shape of a ring is provided, also in the nozzle carrier 7 .
  • This second cavity 15 B is located between the straight extension of the outer shell of the nozzle tube 11 and the outer circumference of the nozzle carrier 7 and runs concentrically with the second cavities 15 B of the nozzle tube 11 .
  • the second cavity 15 B is spaced apart from the outer circumference of the nozzle carrier 7 .
  • All second cavities 15 B may be connected to one another to influence thermal conductivity over the entire nozzle length.
  • the second cavities 15 B in the region of the nozzle tube 11 and the nozzle section 12 as a single piece, for example, as a spiral-shaped or coil-shaped cavity winding around the central axis of the hot runner nozzle 1 .
