Definitions
- the invention relates to a nozzle pressing device for guiding and applying the injection nozzle of an injection unit of an injection molding machine according to the preamble of patent claim 1.
- a nozzle pressing device is known from EP 0193617 A1, in which the injection unit is mounted on a guide carriage which can be driven as a linear drive with a screw drive underneath.
- the injection unit is connected in an articulated manner to the guide carriage by means of a vertical pivot pin in such a way that it can be pivoted out of the side of the injection axis, for example for assembly or maintenance work.
- the screw drive comprises a ball screw, which is rotatable at one end in a bearing attached to the fixed platen, but is not axially displaceable.
- the other end of the threaded spindle is connected via a coupling to the output shaft of a motor for the rotary drive of the threaded spindle.
- a ball nut is rotatably engaged with the ball screw and rotatably supported on the support for the injection unit.
- a spring is arranged between the ball nut and a spring plate attached to the support for the injection unit. By rotating the ball screw, the ball nut and thus the injection unit can be moved towards and away from the fixed platen. The nozzle contact force can be adjusted via the spring constant and the way the spring is compressed.
- a disadvantage of this nozzle pressing device is the asymmetrical introduction of force into the nozzle tip and thus into the fixed half of the injection mold and from there into the fixed mold platen. This results in a comparatively large bending moment, which causes the stationary tool platen and the fixed half of the injection mold attached to it.
- JP 9-277306 To solve this problem, it is known from JP 9-277306 to provide two ball screws in one plane with the spray axis on both sides of the injection unit.
- a nozzle pressing device has the disadvantage that both ball nuts have to be driven synchronously, so that the injection unit does not run out of the injection axis and ultimately a lateral bending moment is nevertheless generated.
- Another disadvantage is that the assembly and maintenance of the plasticizing cylinder is difficult insofar as a lateral pivoting out via a vertical pivot pin is not possible or prior dismantling of at least one ball screw is necessary.
- a nozzle pressing device in which the introduction of bending moments into the fixed half of the injection mold is avoided and which nevertheless allows the plasticizing cylinder to be swung out sideways, is known from the generic US Pat. No. 6524095 B1.
- EP 0193617 A1 it is proposed to mount the injection unit on a guide carriage which can be driven as a linear drive with an underlying screw drive and to further connect the injection unit to the guide carriage in an articulated manner by means of a vertical pivot pin such that it can be pivoted sideways out of the spray axis.
- the ball screw or the bearing device of the ball screw is not attached directly to the fixed platen, but to a specially designed connecting piece.
- This connector has a horizontal part, which is supported on two guide rails on both sides of the centrally arranged ball screw on the machine bed.
- the bearing device for the ball screw is attached below this horizontal part or forms an integral part of this part.
- two vertical webs are provided, which run parallel to the platen, in height end of the spray axis and are screwed there to the platen. The screws are on both sides of the spray axis and in one plane with it.
- the screw connection is not fixed, but loose, in such a way that, on the one hand, the bores in the webs have a slightly larger diameter than the screws and, on the other hand, sleeves between the washers of the screws and the platen are provided in the bores, which are slightly longer than the thickness of the webs in this area, so that a small gap is formed between the platen and the connector.
- the nozzle contact force is passed through the sprue bushing and the fixed half of the injection mold into the fixed mold platen, the connector can deform and tilt slightly compared to the mold platen. Since the ball screw is located below the plasticizing cylinder, it can be pivoted laterally using a pivot pin.
- the connecting piece can also have a vertical piece with a ring, the ring surrounding the nozzle passage opening in the platen. The ring is loosely attached to the fixed platen in the same way as the two webs.
- This nozzle pressing device has the disadvantage that the loose connection between the connecting piece and the platen is comparatively complex to implement. On the one hand, the gap between the connecting piece and the platen and the gap between the sleeve and the bore must not be set too small to ensure adequate tilting of the connecting piece; on the other hand, this gap mass must not be set too large. Since it is also desirable if the screw connection of the connecting piece is as close as possible to the nozzle passage opening, different connecting pieces have to be provided for different diameters of the nozzle passage opening. In contrast, the present invention has for its object to provide an alternative nozzle pressing device, in which the introduction of bending moments into the fixed half of the injection mold or in the injection unit does not occur, but which avoids the disadvantages mentioned above.
- a nozzle pressing device with the features of claim 1.
- a guide carriage which can be driven by a linear drive, for example a spindle drive, is provided, with which the injection unit is articulated horizontally to the spray axis, the guide carriage can are deformed or tilted as a result of the nozzle contact force.
- a linear drive for example a spindle drive
- this deformation or tilting is not transmitted to the injection unit. Therefore, despite the asymmetrical application of force, there is no change in the vertical position of the nozzle.
- the articulated connection can advantageously be in the same horizontal plane with the spray axis.
- the height of the plasticizing cylinder above the machine bed can be varied. If the screw drive is also adjustable in height (dependent claim 9), the entire injection unit can be aligned exactly with the sprue bushing of the injection mold.
- a spindle drive can be provided as the linear drive, for example consisting of a rotationally driven ball screw and a non-rotatable ball nut on the guide carriage.
- a spring plate can be provided on the guide carriage in an articulated manner relative to the spindle drive (dependent claim 6).
- FIG. 1 shows a side view of an injection unit with a nozzle pressing device according to the invention and a fixed part of the closing device; 2 detail from FIG. 1 in the area of the guide carriage; 3 perspective view of the suspension for the worm drive; Fig.4 height adjustment device for the worm drive; 5 shows a perspective view of a guide carriage welded together from several parts; 6 perspective representation of a carriage as a one-piece casting; Fig. 7 articulated connection with eccentric bolts for the carriage; Fig. 8 Use of a flexible joint for the articulated connection between the guide carriage and ball screw drive.
- an injection unit 2 and a stationary mold mounting plate 3 with a fixed mold half 4 are supported on the machine bed 1 of an injection molding machine.
- the remaining parts of the clamping unit are not shown, since they are known per se and are not necessary for understanding the invention.
- a screw (not shown here) is rotatably driven and longitudinally displaceable by means of a screw drive 6.
- a filling funnel 14 is provided for filling plastic granules.
- the plasticizing cylinder 5 has in its rear region left and right-running fastening tabs 32, each with an outer part and an inner part, between which a gap is formed, and is articulated there to a guide carriage 20 which projects into the gap.
- the rear end of the worm is mounted in a bearing device 7 and the worm drive 6 is screwed into a ring 8 which has lateral arms 9 and 10.
- the support of the worm drive on the machine bed 1 will be explained in more detail below.
- This support takes place via support elements 15 and 16 at the rear end of the lateral arms 9 and 10, which are longitudinally displaceable on a linear guide 19 by means of sliding shoes 21.
- a crossbar 17 can be provided between the two arms and additionally supported on an additional linear guide on the machine bed 1 via a further support element 18.
- the lateral support elements 15 and 16 can also be omitted.
- the support elements 15 and 16 in the present case have a height adjustment device, so that the screw drive 6 can be adjusted in height.
- the support elements 15 and 16 can each be designed as hexagon bolts with a threaded section adjoining them.
- the lateral arms 9 and 10 have a suitable internal thread in this area, so that when the hexagon bolt rotates, the respective arm is moved up or down depending on the direction of rotation.
- the hexagon bolts can, for example, simply rest on the slide shoes 21.
- To secure the set height is one Lock nut 49 provided.
- the support elements 15 and 16 can also be designed to be longitudinally displaceable relative to the arms 9 and 10, as is indicated by the broken line on the arms 9 and 10 in FIGS. 3 and 4. This enables the worm drive to be supported at different positions in the machine's longitudinal direction. If, for example, motors for the worm drive with different weights are to be considered, the position of the support elements 15 and 16 can be adapted to the different position of the centers of gravity of these different motors.
- the fastening tabs 32 are attached on both sides of the spray axis for the articulated mounting of the guide carriage. These fastening tabs 32 each have an outer part 32a and an inner part 32b, between each of which a gap 50 is formed for receiving the vertical parts of the guide carriage 20 and which have bores 51 for receiving the pivot pin 29.
- a linear drive in the present case a screw drive, is provided for moving the injection unit 2 back and forth.
- the centrally located ball screw 33 is axially fixed, but rotatable, with its end on the tool side in a bearing device 34 on the fixed platen 3. With its opposite end, the ball screw 33 is also axially fixed but rotatable in a bearing device 35 fastened on the machine bed 1.
- the ball screw 33 is rotatably coupled to the rotor of an electric motor 35 and can be rotated by the latter.
- a ball nut 41 fastened to the guide carriage 20 By means of a ball nut 41 fastened to the guide carriage 20, the rotation of the ball screw 33 is converted into an axial movement of the guide carriage 20 and thus of the injection unit 2.
- the guide carriage 20 has horizontal side pieces 30 and 31 which can be screwed to slide shoes 21, which in turn are engaged with the rail of the linear guide 19, so that the guide carriage 20 is supported on the machine bed 1 in a longitudinally displaceable manner.
- the guide carriage 20 also has two vertical plates 22 and 23 which are connected to one another via one or more support struts 24 and 25 and optionally via a horizontal support plate 26.
- the vertical plates 22 and 23 have bores 27 and 28 for receiving the pivot bolts.
- the left pivot pin 29 is visible, which lies in the bore 28.
- the plates 22 and 23 lying on one level with the ball screw 33 have holes 37 and 38 for receiving pivot pins for an articulated mounting of a spring plate 39.
- FIGS. 1 and 2 only the left pivot pin 40 is visible, which is in the hole 31 lies.
- the ball nut 41 of the spindle drive is attached to the guide carriage 20 in a rotationally fixed manner.
- a spiral spring 42 is arranged between the spring plate 40 and the ball nut 41.
- the ball screw 33 If the ball screw 33 is set in rotation by the electric motor 36, the ball nut 41, and thus the guide carriage 20, moves to the left or to the right, depending on the direction of rotation in FIGS. 1 and 2.
- the injection unit 2 When moving to the left, the injection unit 2 is moved towards the platen 3 until the injection nozzle 44 abuts the sprue bush 43.
- the spiral spring 42 With further rotation of the ball screw 33, the spiral spring 42 is compressed by the ball nut 41 and the injection nozzle 44 is pressed firmly against the sprue bush 43.
- the carriage can be designed as a welded construction (see Figure 5) or in one piece as a casting (see Figure 6).
- the nozzle contact force is adjustable via the spring constant and the spring travel and is introduced into the injection unit 2 via the guide carriage 20 without bending moments directly at the level of the spray axis (and thus through the plane of the plasticizing cylinder). This also ensures that the tie rods 11 and 12 are only on train are stressed and not also a bend occurs. This does not falsify the measurement of the melt pressure in the screw vestibule, to determine the dynamic pressure and / or the injection force, via the linear expansion of the tie rods by means of the strain gauges 13.
- Eccentric bolts 52 can also be provided as pivot bolts for the articulated connection between guide carriage 20 and plasticizing cylinder 5 and / or between guide carriage 20 and spring plate 39, as shown in FIG.
- the vertical plate of the guide carriage 20 projecting into the gap 50 between the outer part 32a and the inner part 32b of the fastening tab 32 is not shown.
- the eccentric bolts 52 By adjusting the eccentric bolts 52 by rotating the square head 53, the height of the plasticizing cylinder 5 above the machine bed 1 can be varied.
- a U-shaped bracket encompassing the plasticizing cylinder 5 can be used, for example, the ends of the U each having an opening for gripping around the square head 53.
- the exact position of the plasticizing cylinder 5 in relation to the tool 4 can be set by means of the rotary bolts on the one hand, and here in particular also the eccentric bolts, and the height adjustment screws on the worm drive, so that the nozzle 44 lies exactly in the sprue bush 43. A sufficiently large nozzle pressure can then also be exerted. In addition, large nozzle bore cross sections can be provided. Furthermore, there are no restrictions with regard to the nozzle designs and the materials that can be used.
- the nozzle pressure force is introduced into the tool without bending moments.
- the position of the nozzle can be set precisely and quickly.
- no bending moment is introduced into the plasticizing cylinder, there is no risk of the plasticizing screw breaking or there is increased friction between the plasticizing screw and the inner wall of the plasticizing cylinder.
- a flexible joint is to be understood as an elastically deformable machine element which is provided between the guide carriage and the plasticizing cylinder and / or between the guide carriage and the spring plate.
- FIG. 8 shows an example of the use of a torsion bar 54 which has end pieces 55 and 56 with which it is fastened on the one hand to the guide carriage 20 and on the other hand to the spring plate 39.
- the torsional elasticity of the torsion bar 54 is selected so that a small rotation between the spring plate 39 and the guide carriage 20 is possible.
- the flexible joint can also be an integral part of the guide carriage.
