Description
Technical Field
The present invention relates to a closing unit for a moulding machine (for example an injection moulding machine) and a method for adjusting the plate parallelism of one clamping plate of the closing unit of such a moulding machine with respect to the other clamping plate of the closing unit of the moulding machine.
Background
In order to orient the clamping plates parallel to each other, the plate parallelism must be adjusted at least once (usually at the shop). For this purpose, at least one of the adjusting nuts is rotated (with the transmission removed or not installed) relative to the threaded rod until the clamping jaws are oriented almost parallel to one another. However, only a coarse adjustment of the plate parallelism is possible with this method, since it is not possible to take into account inaccuracies caused by the external toothing of the adjusting nut and the thread pitch of the adjusting nut or of the screw. If the outer toothing of the adjusting nut has, for example, 100 teeth and the thread pitch is, for example, 4mm, an inaccuracy of 40 μm results.
Adjustment of the plate parallelism is used to achieve the desired closing force profile. In such molding machines, a closing force is applied to the mold halves clamped onto the clamping plates of the closing unit by means of a closing mechanism, which presses the two clamping plates towards each other.
Disclosure of Invention
The object of the invention is to provide a closing unit and a method for adjusting the plate parallelism of one clamping plate of a closing unit of a moulding machine relative to the other clamping plate of the closing unit of the moulding machine, wherein the plate parallelism can be adjusted more accurately.
To this end, the invention proposes a closing unit for a forming machine comprising at least two die plates and comprising an adjustment device for adjusting one of said at least two die plates with respect to the other die plate, wherein said adjustment device comprises: at least two spindle drives, each having an adjusting nut which interacts with the spindle via a thread having a pitch, wherein the adjusting nuts each have an external toothing having a plurality of teeth, and the adjusting nut is arranged rotatably on one of the at least two clamping jaws and the spindle is supported on at least one support, -a drive having an toothing which interacts with the adjusting nut via a corresponding external toothing of the adjusting nut, -a motor for driving the drive, characterized in that the spindle of at least one of the at least two spindle drives is supported in a rotationally fixed manner on the at least one support by means of a releasable rotationally fixed structure, and the spindle is rotatable relative to the support after the rotationally fixed structure has been released.
The invention also proposes a closing unit for a forming machine comprising at least two die plates and comprising an adjustment device for adjusting one of said at least two die plates with respect to the other die plate, wherein said adjustment device comprises: at least two spindle drives, each having an adjusting nut which interacts with the spindle via a thread having a pitch, wherein the adjusting nuts each have an external toothing having a plurality of teeth, and the adjusting nut is arranged rotatably on one of the at least two clamping jaws, and the spindle is supported on at least one support element, -a drive having an toothing which interacts with the adjusting nut via a corresponding external toothing of the adjusting nut, -a motor for driving the drive, characterized in that the external toothing of at least one of the adjusting nuts is supported on the adjusting nut in a rotationally fixed manner by means of a releasable rotationally fixed structure, and the external toothing is rotatable relative to the adjusting nut after the rotationally fixed structure has been released.
The invention also proposes a method for adjusting the plate parallelism of a gripper plate of a closing unit of a moulding machine according to the invention with respect to another gripper plate of the closing unit of the moulding machine, wherein a coarse adjustment of the plate parallelism is first carried out, wherein at least one of the adjusting nuts is adjusted along the screw to such an extent, with or without the transmission being removed, until a plate parallelism is adjusted, except for inaccuracies produced by the outer toothing of the adjusting nut and the pitch of the thread, characterized in that subsequently: -loosening the anti-twist structure of at least one of the threaded rods on the at least one support and rotating the threaded rod relative to the support until the desired plate parallelism is reached, or-loosening the anti-twist structure of the external toothing of at least one of the adjusting nuts on the adjusting nut and rotating the external toothing relative to the adjusting nut after loosening the anti-twist structure until the desired plate parallelism is reached.
Since in the first variant of the invention the threaded spindle of at least one of the at least two spindle drives is supported on at least one support by means of a releasable anti-rotation mechanism and can be rotated relative to the support after the anti-rotation mechanism has been released, the adjustment of the plate parallelism can be carried out independently of the engagement of the external thread of the adjusting nut and independently of the pitch of the thread of the adjusting nut or of the thread of the threaded spindle.
If the threaded spindle is rotated to such an extent relative to the support after the anti-rotation device has been released, until the adjusting nut can be moved along the threaded spindle by the following value: this value is equal to the pitch divided by the number of teeth of the external toothing of the adjusting nut, so that the inaccuracies discussed above are counteracted.
A second variant of the invention provides that the external engagement section of at least one of the adjusting nuts is supported on the adjusting nut by means of a releasable anti-rotation mechanism, and that the external engagement section is rotatable relative to the adjusting nut after the anti-rotation mechanism has been released. In this way, the adjustment of the plate parallelism can also be carried out without depending on the engagement of the external thread of the adjusting nut and without depending on the pitch of the thread of the adjusting nut or of the thread of the threaded spindle.
The transmission device for transmitting the drive force of the motor to the at least two spindle drives can be designed, for example, as a toothed belt, a sun gear, a chain or the like

Detailed Description
Fig. 1 shows a closing unit 1 of a molding machine, which is designed here as an injection molding machine. Here, an injection molding machine without a beam is provided, wherein the force flow during the creation of the closing force is not closed by the beam, but rather by a machine frame, which is embodied here as a C-frame. Two clamping jaws 2 are provided, on which a mold half, not shown here, is placed during operation, into which the plastic melt is injected.
The clamping plate 2 located on the right in fig. 1 (which may include an articulated bearing device if necessary to prevent the half-moulds fixed to the clamping plate 2 from opening under the closing force) is fixedly connected to the machine frame. The gripper plate 2 located to the left in fig. 1 can be moved by an adjusting device, which can be better seen in fig. 2, having two spindle drives for carrying out a quick-action reciprocating movement relative to the gripper plate 2 located to the right (i.e. until the mold half resting on the gripper plate 2 is touched).
In order to generate the closing force, a closing mechanism is provided, which is designed here in the form of a toggle lever mechanism. Other closure mechanisms are known to those skilled in the art and may be used in the present invention. The curved bar is clamped against a bearing 12 of the screw 3 of the screw drive.
The screw drive has two variants of the invention (see fig. 3a, 3b, where, although the first variant of the invention can be seen, the second variant of the invention or a combination of the two variants can also be used):
each having an adjusting nut 4 which interacts with the threaded spindle 3 by means of a thread having a thread pitch, wherein the adjusting nuts 4 each have an outer toothing having a plurality of teeth and are arranged rotatably on the left-hand clamping die plate 2 in fig. 1, and the threaded spindle 3 is supported on a support 12 on which the closing mechanism engages.
A gear 5 with a toothing, which interacts with the adjusting nut 4 via a corresponding external toothing of the adjusting nut, wherein the gear 5 is designed here as a toothed belt.
A motor 6 for driving the transmission 5, wherein a deflection roller 13 is also designed for the toothed belt.
A first variant of the invention is discussed with the aid of fig. 2 to 4.
First, for coarse adjustment, the actuator 5 is removed, or coarse adjustment is performed at a point in time when the actuator 5 is not yet installed. For coarse adjustment, at least one of the two adjusting nuts 4 is advanced or swiveled away (relative to the clamping template 2 located to the left in fig. 1). The coarse adjustment can be "true to one tooth" (i.e. with the inaccuracy that is produced on the basis of the pitch of the toothing) in the best case, on the basis of the toothing of the gear 5 and the external toothing of the adjusting nut 4. It can be seen that the coarse adjustment is already completed as best as possible once the parallelism of the clamping jaws 2 changes by one pitch when the adjusting nut 4 is turned.
The parallelism is then measured and, if necessary, fine-tuned.
For fine adjustment, the transmission 5 is first installed.
Fig. 3b shows a central opening 14 and two lateral openings 8 for an ejector (not shown), which can optionally be covered by a cover and each allow access to the head of a fixing screw 7, which passes axially through the respective spindle 3 and by which the spindle 3 is fixed to the support 12 (see fig. 2a, 2 b). Now, the fixing screw 7 of at least one of the two threaded rods 3 is loosened. However, the fixing screw(s) 7 should not be completely rotated out of the support(s) 12. In order to operate the set screw(s) 7, it may be necessary to use extensions for a socket wrench.
In a first variant of the invention, the anti-rotation device of a spindle drive has a holding plate 9 (see, for example, fig. 2a, 2b) which is connected to the spindle 3 and is provided with an elongated hole 10 (see fig. 4) which extends over an angular range and through which the holding plate is screwed to the bearing 12 by means of a screw 11, wherein the anti-rotation device is releasable by releasing the screw 11 and the spindle 3 is rotatable relative to the bearing 12 over the angular range of the elongated hole 10 of the holding plate 9 after releasing the screw 11. In the exemplary embodiment shown, the anti-rotation means of each spindle drive have two elongated holes 10 with in each case one screw 11.
The two screws 11 of the anti-rotation mechanism of at least one of the spindle drives are now released and the respective spindle 3 is rotated on the holding plate 9 (to the left or to the right in fig. 4). Thereby achieving the adjustment of the adjusting nut 4 closer to or farther from the die plate 2. The spindle 3 can be rotated relative to the support 12 to such an extent after the anti-rotation mechanism has been released, until the adjusting nut 4 can be rotated along the spindle 3 by the following amount: this value is equal to the pitch divided by the number of teeth of the external toothing of the adjusting nut 4.
If the desired parallelism of the clamping jaws 2 is reached, the screws 11 of the anti-rotation structure are screwed on. The fixing screws 7 are then tightened and, if necessary, a cover for the upper opening 8 is also fitted. And finishing fine adjustment.
Fig. 5a, 5b show a second variant of the invention. The external engagement of at least one of the adjusting nuts 4 is supported on the adjusting nut 4 via a part 15 by a releasable anti-rotation mechanism and, after releasing the anti-rotation mechanism, is rotatable relative to the adjusting nut 4. The anti-rotation device comprises at least one screw 16 which passes through an elongated hole 17 and connects the part 15 supporting the external engagement part to the rest of the adjusting nut 4. In the exemplary embodiment shown, the anti-rotation device comprises a total of four elongated holes 17, each of which is associated with a respective screw 16.
After loosening the anti-rotation structure of the external toothing of at least one of the adjusting nuts 4, said part 15 is rotatable with respect to the adjusting nut 4 to such an extent that the adjusting nut 4 can be rotated along the threaded rod 3 by the following value: this value is equal to the pitch divided by the number of teeth of the external toothing of the adjusting nut 4. This results in the same advantages as the first variant of the invention.
