Definitions
- the invention relates to an injection molding apparatus according to claim 1.
- Injection molding devices are known in numerous embodiments. They are used for example as hot or cold runner systems to supply a flowable plastic mass at a predetermined temperature and under high pressure a separable tool block (mold cavity).
- a plurality of - also temperable - nozzles are usually mounted on a temperature-controlled distribution system, which deliver the material to be processed metered via a flow channel in the mold cavity.
- Each nozzle usually has at its end facing the manifold a flange or stepped connection head which abuts with a flat sealing surface on a flat face or side surface of the manifold (see DE-U1-201 00 840).
- the clamping force required for fixing the nozzle is produced, for example, by means of screws which are screwed into the distributor through the connection head provided with holes at the edge.
- EP-B1-0 732 185 provides through holes in the distributor. The screws inserted therein engage on the opposite side in a clamping ring which engages over the connection head of the nozzle and clamped firmly against the manifold.
- a sealing ring may additionally be provided in the region of the central inlet opening for the flow channel in the nozzle body.
- the disadvantage here is that during heating of the system, the distributor can push away through the resulting thermal expansion over the nozzles, ie it arises - despite some high clamping forces between the nozzle and distributor - a sliding movement between the sealing surfaces of the nozzle body and the front or side surfaces of the distributor, with the result that the outlet openings of the distributor and the inlet openings of the nozzles can move to each other.
- the outlet openings of the distributor and the inlet openings of the nozzles can move to each other.
- the nozzles can also tilt by the transverse forces that occur, resulting in further leakage.
- EP-B1-0 732 185 uses a dowel pin assembly. This comprises a plurality of dowel pins, which are positively brought into engagement with the manifold and the retaining ring. Although such an arrangement proves to be secure in position, it makes assembly considerably difficult, especially when a plurality of nozzles are to be mounted. Moreover, EP-B1-0 732 185 requires that lateral movement between manifold and nozzle should always be possible.
- the aim of the invention is to avoid these and other disadvantages of the prior art and to provide an injection molding device which allows a simple and quick installation of all nozzles on a manifold and ensures an always permanent sealing of all nozzles with respect to the manifold.
- the distributor and the nozzles can move relative to each other after installation.
- the aim is also a simple structure that is always easy to handle even with a variety of nozzles.
- the entire device should be inexpensive to produce.
- the invention provides according to claim 1, that the holding element has at least one centering and / or fixing, which is mounted longitudinally displaceable and in the final assembled position with the distributor is engageable in such a way that this and the nozzle are fixed in position relative to each other.
- the fixing of the position ensures that the distributor can no longer slide over the nozzles. These are always firmly fixed, even if the distributor should move slightly due to its thermal expansion.
- the outlet openings of the Distributor and the inlet openings of the nozzles are always congruent one above the other due to the centering or fixing and can no longer move to each other.
- the material to be processed can flow unhindered into the nozzles.
- the previous assembly is designed as simple as inexpensive, because the longitudinally displaceable fixing elements can first withdraw behind the respective holding element or flush with this, so that first - as usual - the nozzles mounted and then the distributor can be placed.
- Existing fits or pins need not be taken into account, which would be difficult to cope with, especially when using very many nozzles. If the manifold is on, all the nozzles can now be aligned and fixed quickly and conveniently one after the other, because all the longitudinally displaceable fixing elements can be engaged with the distributor in sequence. The work and time required is extremely low. All nozzles are always fixed even with a thermal expansion of the manifold.
- the holding element has at least one recess for receiving the nozzle. This is - always held securely over a widened connection head -, wherein over the holding element, a uniform compressive stress can be generated.
- Claim 3 provides that the holding element has at least one further recess for receiving the fixing element, which is mounted longitudinally displaceable according to claim 4 in the further recess.
- the fixing element is always exactly guided.
- the fixing element is in direct connection with the holding element, which contributes to the precise position fixing and adjustment.
- the fixing element which therefore also has the function of a centering element, arranged or aligned parallel to the longitudinal axis of the nozzle according to claim 5.
- the fixing element can be brought into positive engagement with the distributor.
- the holding element further comprises a collar, a projection, a hook or the like. which forms a second stop. At first, the fixing element can not readily slide over it.
- the distance between the top of the holding element and the second stop in accordance with claim 11 is greater than the length of the fixing element. This can thus always withdraw behind the preferably flat top of the retaining element. The distributor can thus be placed on the nozzles without any obstacle.
- the formation of claim 12 provides that the thickness of the support member is perpendicular to the longitudinal axis and perpendicular to the width of the nozzle is less than or equal to the thickness perpendicular to the longitudinal axis and perpendicular to the width of the nozzle.
- the holding element forms no obstacle when it comes to arrange as many (flat) nozzles with tight pitches one behind the other.
- the retaining elements fit easily into the manifold-nozzle arrangement and ensure a permanently correct position of all nozzles.
- the screw connection according to claim 16 has at least one screw which can be brought into engagement with the fixing element. So that this does not rotate when screwing in the screw, the fixing element according to claim 17 against the retaining element is mounted against rotation. Additionally or alternatively, the screw according to claim 18 have at least one screw which can be brought directly into engagement with the holding element.
- the fixing element in the embodiment of claim 19 is a sleeve, with a cylindrical shaft and a flange edge formed at the end. If the fixing element is grasped and tightened by the screw, the sleeve is supported by the flange edge against the first stop of the retaining element. The latter is firmly clamped against the distributor. So that Screw can engage in the sleeve, an internal thread is formed according to claim 20 within the shaft.
- the flange edge is laterally flattened to form two parallel key surfaces (claim 21). If you turn this aside, you can introduce the centering sleeve past the second stop in the further recess of the retaining element. On the other hand, if the fixing element is rotated by 90 °, for example, the flange edge is supported on the second stop. The fixing element can no longer slide out of the retaining element. At the same time, the fixing element is behind the retaining element, so that the distributor can be placed on the nozzles unhindered.
- At least two fixing elements are provided, which has a favorable effect on the force distribution. This also contributes to claim 23, namely, when the fixing elements are arranged symmetrically to the longitudinal axis of the nozzle. However, as required, the fixing elements can also be arranged in accordance with claim 24 in a triangle or in a circle around the longitudinal axis of the nozzle.
- the holding member can receive at least two nozzles according to claim 25, whereby the number of gate points can be further increased.
- the nozzles according to claim 26 expediently have a common heating element.
- the contact pressure of the nozzles can be increased against the manifold, namely, if each nozzle is spring-loaded within the recess of the retaining element.
- nozzle, the holding element and the fixing elements form a preassembled or preassembled unit.
- the nozzles are delivered with the holding element and the fixing elements and can be installed directly. Warehousing and logistics are noticeably relieved.
- the nozzle and the holding element are integral, which may be advantageous depending on the embodiment.

- FIG. 3 shows another embodiment of an injection molding apparatus
- FIG. 4 shows another embodiment of an injection molding apparatus.
- the generally designated 10 in Fig. 1 injection molding device is used to process a molten material, such as a plastic melt. It includes - in addition to other (not shown) components, such as a feeder for the material to be processed, a nest plate shape with mold inserts and the like. a temperature-controllable distributor 20 and at least one hot runner nozzle 30 mounted thereon, each hot runner nozzle 30 being fixable to the distributor 20 with a holding element 40.
- the distributor 20 is formed by a distributor plate 21, which has a substantially flat upper side 22 and parallel to a substantially flat bottom 23.
- a plurality of flow channels 24 are introduced, which open into outlet openings 26 in the bottom 23 of the plate 21.
- Symmetrical to each outlet opening 24 are two through holes 27 are introduced in the plate 21, which are provided at the top 22 of the plate 21 with a stepped recess 28 and on the underside 23 of the plate 21 with a likewise enlarged diameter fit 29.
- the hot runner nozzle 30 has a (not shown) nozzle body with a laterally flattened connection head 31 and an axially downwardly adjoining narrower shaft 32.
- the (also unspecified) thickness of the connection head 31 transverse to the longitudinal axis A and transverse to the width B of the nozzle 30 is only slightly larger than the diameter of the shaft 32, so that the nozzle body is made narrow overall.
- a (not visible) flow channel is centrally introduced, which has a material inlet opening 33 in the connection head 31 and at its lower end in a nozzle tip 34th opens, which directs the molten material via at least one material outlet opening 35 in the mold cavity.
- a sealing ring 36 is provided concentrically with the material inlet opening 33 in the connection head 31 of the nozzle body.
- a radiator 37 is mounted on the outer circumference of the shaft 32.
- This has the shape of a flat solid block, which extends over almost the entire axial length of the nozzle shaft 32.
- a first receiving channel (not shown) in the form of a through-bore is introduced for receiving the nozzle shaft 32.
- Its inner diameter is slightly smaller than the outer diameter of the shaft 32, so that the latter is always positively enclosed by the heater 37 for a good heat transfer.
- the thickness D of the heater 37 transversely to the longitudinal axis A and transverse to the width B of the nozzle 30 is only slightly larger than the thickness of the laterally flattened connection head 31.
- the hot runner nozzle 30 together with heater 37 is formed very flat overall.
- each heating cartridge 38 is slightly larger than the inner diameter of the preferably open at the top and bottom receiving channels, so that the heating cartridges 38 are always surrounded with good thermal contact of the highly heat-conductive material of the solid block 37.
- the heating power generated by the heating cartridges 38 is always optimally delivered to the solid block 37 and from this to the nozzle body 31, 32.
- an additional (not visible) receiving channel is provided in the immediate vicinity of the nozzle shaft 32, in which a (not shown) temperature sensor can be used. Also, its terminals 39 'can be led away laterally from the radiator 37 and connect to the control circuit.
- the holding member 40 biases the hot runner nozzle 30 in the longitudinal direction A against the underside 23 of the distributor 20. It has for this purpose a bar-shaped main part 43, the for receiving the connection head 31 and for carrying out the nozzle shaft 32 is provided with a central recess 41. Two guided in the through holes 27 of the manifold 20 screw 14 engage behind the bar 43, so that this uniformly attracted and the connection head 31 of the nozzle 30 can be pressed tightly against the distributor bottom 23.
- the bar 43 is wider than the connecting head 31 and the nozzle 30.
- the thickness d of the main part 43 perpendicular to the longitudinal axis A shows - not greater than the thickness D of Heater 37 and the nozzle 30, so that change the horizontal mounting dimensions of the nozzle 30 by the holding member 40 only slightly.
- the hot runner nozzles 30 can be - as shown in FIG. 3 - several times in succession mounted at minimum intervals, so that several mold cavities or multiple runners can be injected simultaneously.
- the spacing distances or the distances between the sprue points can be selected to be extremely small at least in one direction transverse to the axial direction A.
- two centering or fixing elements 50 are provided in the holding element 40 symmetrically to the nozzle axis A, which are mounted longitudinally displaceable as components of the screw 14 and positively in the final assembled position with the fits 29 in Distributor 20 are engageable, so that the nozzle 30 is fixed in position relative to the manifold 20.
- Each fixing element 50 is formed as an elongated sleeve, with a cylindrical shaft 52 and a flange edge formed at the end 54.
- the shaft 52 is guided with little play in a further recess 42 in the bar-shaped main part 43 parallel to the longitudinal axis A of the nozzle 30 longitudinally displaceable and with a Provided internal thread 53, into which a screw 15 of the screw 14 engages.
- the flange 54 sets the centering sleeve 50 when tightening the screws 15 to the preferably flat bottom 44 of the beam 43 at.
- the fixing elements 50 which are mounted so as to be longitudinally displaceable in the recesses 42, engage with their shaft ends 56 in a form-fitting manner with the fits 29 in the distributor 20.
- the holding element 40 thus not only presses the nozzle 30 firmly against the distributor 20. It also secures the position of the nozzle 30 perpendicular to the longitudinal axis A via the centering or fixing elements 50, so that the distributor 20 and the nozzles 30 after the Can no longer move assembly relative to each other.
- the fixing elements 50 have a dual function. On the one hand, they prevent any sliding movement between the distributor 20 and the nozzles 30. At the same time, they advantageously form fastening elements for the holding element 40, so that the overall constructive effort is low.
- the through holes 27 in the manifold 20 and the recesses 41, 42 in the holding member 40 are arranged so that the nozzle 30 is pressed with its connection head 31 against the underside 23 of the manifold 20 so that the material inlet opening 33 of the nozzle 30 is always concentric with Material outlet opening 26 in the manifold 20 is located.
- the fixing elements 50 thus at the same time also form centering elements for the hot runner nozzle 30.
- the fixing elements 50 mounted longitudinally displaceably in the holding element 40 can simply be pushed back behind the upper side 45 of the bar 43 before assembly.
- a nozzle 30 inserted into the holding element 40 from above can thus initially set flat against the underside 23 of the distributor 20, without having to take care of fitting, centering or fixing elements.
- the distributor plate 21 can be placed flat on the nozzles 30 or the holding elements 40.
- the subsequently inserted into the through holes 27 screws 15 engage from above into the fixing elements 50 and pull them parallel to the longitudinal axis A through the holding elements 40 into the respective fit 29 inside.
- the nozzles 30 are thus sequentially fixed both axially and laterally.
- an anti-twist device (not shown) is provided between the shaft 52 and the further recesses 42 in the retaining element 40. But you can also form the rotation between the flange 54 and the support member.
- a shaft-shaped section 47 is formed on the underside 44 of the beam 43, the end being directed radially outward Collar 46 forms.
- each fixing element 50 is supported in the unassembled state with its flange edge 54 from.
- the distance H between the upper side 45 of the holding element 40 and the collar 46 is greater than the length I of the fixing element 50. This is thus always behind the top 45 of the holding member 40 before mounting the nozzle 30.
- the collar 46 and the shaft 47 are laterally flattened so that the total thickness d of the holding element 40 is not greater than the total thickness D of the nozzle 30.
- the flange edge 54 is flattened laterally to form two parallel key surfaces 55. If one therefore rotates the fixing elements 50 such that the wrench surfaces 55 lie transversely in front of the collar 46, the sleeve 50 can be inserted with the shaft 52 from below into the retaining element 40. As soon as the flange edge 54 has passed the collar 46, the key surfaces 55 are rotated by 90 °. As a result, the flange edge 54 now lies between the collar 46 and the underside 44 of the retaining element 40. The sleeve 50 can not slide up or down out of the retaining element 40. The centering or fixing element 50 is captively connected to the retaining element 40.
- a first stop is formed by the underside 44 of the retaining element 40, while the collar 46 is a second stop for the fixing element 50.
- two nozzle bodies are inserted in the holding element 40.
- the bar-shaped main part 43 is correspondingly provided with two recesses 41 for two connection heads 31, which each pass into a narrow nozzle shaft 32.
- the bar 43 supports at its outer ends the centering or fixing 50, which are each guided in the other recesses 42 and form as fixing nuts together with the screws 15, the screw 14.
- a bore 48 is introduced with an internal thread 49.
- the screw 17 is supported with its recessed head 18 in the manifold 20 and thereby pulls the retaining element 40 in addition against the bottom 23 of the manifold 20.
- the contact pressure on the nozzle 30 is thereby further increased.
- the through holes 27, 27 'in the distributor and the recesses 42, 48 in the holding element are preferably symmetrical to the longitudinal axis A on a line, so that the outlet opening 26 in the manifold 20 and the inlet opening 33 in the nozzle 30 are always congruent one above the other and the nozzle 30th can be mounted with tight pitches.
- nozzle 30, the holding member 40 and the fixing elements 50 form a preassembled or preassembled unit, which are first inserted into the tool 10 and then successively fixed in position on the patch distributor 20 and centered.
- the invention is not limited to one of the above-described embodiments, but can be modified in many ways. So you can use instead of a flat block heater 37 and another form of heating, such as a Wendel carving redesign. Again, this can be quickly and easily mounted on the nozzle shaft 32 after placing the holding elements 40 on the nozzle body.
- the injection molding apparatus 10 can also be designed overall as a cold runner system. The nozzle 30 is then a cold runner nozzle.
- the holding member 40 may be to secure the fixing elements 50 in the recesses 42 instead of a collar 46 a projection, a hook or the like. have, which engages behind the flange edge 54 of the fixing elements 50. You can also form a pin guide or a kind of bayonet connection. It is crucial that the fixing elements 50 after insertion into the recesses 42 find a backward stop so that the nozzles 30 can be attached flat to the manifold 20. Only then do the screws 15 engage in the internal threads 53 of the anti-rotation locking nuts 50 and pull them against the retaining element 40.
- the fixing elements 50 can - if sufficient space is available - if necessary, in a triangle or in a circle around the longitudinal axis A of the nozzle 30 around be arranged. In order to further increase the contact pressure of the nozzles 30 and to compensate for heat-related changes in length, the nozzles 30 may be spring-loaded within the recess 41 of the retaining element 40.
- the nozzles 30 and the holding element 40 are preferably formed separately from each other. You can also manufacture them in one piece if required.
