Description

The present invention relates to a shaping machine and/or an assembly for a shaping machine with at least one pull or push rod having the features of the preamble of claim 1 and a method for adjusting such a pull or push rod.

In this case, shaping machines can be understood to mean injection molding machines, transfer presses, die casting machines or the like. An assembly of a shaping machine can be understood to mean a closing unit of a shaping machine, a plasticizing unit of a shaping machine, add-on elements of a shaping machine or the like. The prior art is presented below using a plasticizing unit of an injection molding machine. The same applies in relation to general shaping machines and/or general assemblies for shaping machines.

Known from the prior art embodiments of injection molding go for example from US 3,204,294A and the DE 600 14 808 T2 out.

In injection molding machines, the contact pressure (with which a plasticizing unit is pressed against a closing unit) is an important parameter. As a rule, an injection nozzle of the plasticizing unit is pressed against an injection opening of a molding tool, which is mounted on a fixed mold clamping plate of the clamping unit.

The requirement here is for the plasticizing unit to be applied quickly, but as gently as possible, using a sufficiently large contact force so that no plasticized mass escapes between the plasticizing unit and the clamping unit during the injection process due to the extremely high pressures (several 1000 bar), since material leakage directly affects the quality of the end product .

In order to press the plasticizing unit onto the clamping unit, it is known from the prior art to use pull or push rods which connect the plasticizing unit to the clamping unit (strictly speaking, to the fixed mold mounting platen of the clamping unit). An actuator is usually provided on the plasticizing unit, which is connected to these pull or push rods. In this embodiment, the actuator can build up a tensile force between the plasticizing unit and the pull or push rod, which puts the plasticizing unit, which is supported on the closing unit, under a compressive force (contact force).

The pull or push rods are manufactured depending on the application and machine configuration of an injection molding machine. Depending on the clamping unit, machine bed and plasticizing unit, there are different distances or lengths for the pull or push rods. The length of the plasticizing cylinder or the nozzle length of a plasticizing unit can also influence this length of the pull or push rod.

As a result, when changing the plasticizing unit or the nozzle of the plasticizing unit, the pull or push rods also have to be changed. The disadvantage here is that this makes it necessary to provide several pull or push rods, which leads to increased procurement costs, complex storage work and increased set-up times.

The object of the invention is to provide a shaping machine and/or an assembly for a shaping machine with at least one pull or push rod and a method for adjusting the length of such a pull or push rod, which represent an improvement over the prior art.

This object is achieved by a shaping machine and/or an assembly for a shaping machine having the features of claim 1 and a method having the features of claim 14.

According to the invention, it is provided that the pull or push rod is provided for power transmission to a movable mold clamping platen of the shaping machine, in particular for generating a driving force for a rapid lifting device, the at least one pull or push rod having at least a first pull or push component and at least a second pull - or compression component, wherein at least one connecting device is provided, by means of which at least one connecting device the at least one first tension or compression component and the at least one second tension or compression component can be releasably connected to one another in different positions, the at least one tension or compression rod has a different axial length to one another in the different positions of the tensile or compressive components.

By providing at least one first and at least one second tension or compression component, which can be detachably connected to one another by a connecting device, an axial length of the at least one tension or compression rod can be selected depending on the area of application, whereby the at least one tension or compression rod with their axial length a desired distance between, for example, a plasticizing unit and a closing unit is adjustable. The provision of several pull or push rods, which have to be exchanged each time the arrangement is changed, is eliminated, as are the associated acquisition and storage costs.

Another advantage of the invention is that the at least one pull or push rod can be easily and quickly adjusted to a desired length by releasing the connecting device between the at least one first pull or push component and the at least one second pull or push component. This leads to shorter set-up times, which increases productivity.

The power transmission according to the invention can involve the application of a tensile or compressive force to a (relatively) static element (for example contact pressure in a plasticizing unit) or the transmission of a driving force for a machine movement.

The invention can therefore also be used, for example, in an express lifting device for a moving platen of a clamping unit, as a result of which the rapid lifting device can be adapted to the installation height of a mold.

Advantageous embodiments of the invention are defined in the dependent claims.

Provision is preferably made for the shaping machine and/or an assembly for a shaping machine to have at least one actuator, by means of which at least one actuator the at least one pull or push rod can be subjected to a force. Provision is particularly preferably made for the at least one actuator of the shaping machine and/or an assembly for a shaping machine to be designed as a piston-cylinder unit and/or a spindle drive.

Provision can be made for the at least one first tension or compression component to have a first fastening device for fastening the at least one tension or compression rod on a side facing away from the connecting device. This first fastening device can be designed, for example, as a flange which is screwed onto the plasticizing unit or an actuator of the plasticizing unit.

However, it can also be provided that the at least one first tension or compression component is formed on a side facing away from the connecting device as part of the actuator—preferably as a piston of the piston-cylinder unit. Accordingly, it can be provided that the first fastening device is a piston-cylinder unit of the shaping machine and/or an assembly for a shaping machine itself, with the first tension or compression component being at least partially designed as a piston of the piston-cylinder unit and being Piston-cylinder unit is connected to the molding machine and / or an assembly for a molding machine.

Provision can be made for the at least one second tension or pressure component to have a second fastening device for fastening the at least one tension or compression rod to the clamping unit—preferably to a fixed mold clamping plate—and/or a mold on a side facing away from the connecting device. This second fastening device can be designed, for example, as a flange, which can be fastened to the mold or the fixed platen by a screw connection. However, it can also be provided that this second fastening device has an eyelet which can be held by a bolt on the mold or the fixed mold mounting plate.

It is preferably provided that the at least one first tensile or compressive component and/or the at least one second tensile or compressive component is designed as a—preferably rotationally symmetrical—rod. Provision can thus be made for the at least one first tension or compression component and/or the at least one second tension or compression component to be made from standardized rod material, which leads to reduced production complexity and thus lower production costs.

• 6a , 6b another embodiment of a shaping machine according to the invention.

1a and 1b show an embodiment of a pull or push rod 1 of a shaping machine 25 in an isometric view, wherein the 1b the embodiment of the 1a with a sectioned second tension or compression component 3, so that the individual components of the tension or compression rod 1 can be seen. the 2a shows the embodiment of 1a and 1b in a side view, with the 2 B a cut AA's 2a represents.

The embodiment of the pull or push rod 1, which by the 1 a until 2 B is shown has a first train or compression component 2 and a second train or compression component 3 . This first tensile or compressive component 2 and the second tensile or compressive component 3 are connected to one another by a connecting device 4 which is formed by a clamping device 9 in this specific exemplary embodiment. In this exemplary embodiment, the second tension or compression component 3 is designed as a sleeve, with the first tension or compression component 2 (which is designed as a rod) being telescopic into the second tension or compression component 3 . Such a configuration has the particular advantage that forces can be transmitted particularly favorably between the first tensile or compressive component 2 and the second tensile or compressive component 3, since the resulting forces of the first and second tensile or compressive components 2, 3 along the same axis (along the central axis 5) act.

The first tension or compression component 2 has a first fastening device 6 which is designed as a piston 8 in this exemplary embodiment. This piston 8 subsequently forms the piston 8 of a piston-cylinder unit 18, 19 of a plasticizing unit 11, the piston 8 being able to be fastened to or in the plasticizing unit 11 by the piston-cylinder unit 18, 19.

Furthermore, the second tension or compression component 3 designed as a sleeve has a second fastening device 7 in order to fasten the tension or compression rod 1 to a closing unit 24 of a shaping machine 25 . This second fastening device 7 is designed as an eyelet in this specific exemplary embodiment, it being possible for this eyelet to be held by a bolt. The second fastening device 7 is fastened in the second tension or compression component 3 by a thread.

The connecting device 4 of the pull or push rod 1 is designed as a clamping device 9 . This clamping device 9 can fix a position of the first tensile or compressive component 2 to the second tensile or compressive component 3 by clamping between the second tensile or compressive component 3 designed as a sleeve and the first tensile or compressive component 2 designed as a rod and forces between the Transfer tensile or compressive components. Such a clamping device 9 can be formed by a hydraulic clamping bush, a shrink connection, a clamping connection or a mechanical clamping set, as are known from the prior art.

In this exemplary embodiment, the first tensile or compressive component 2 and the second tensile or compressive component 3 are arranged coaxially with one another, as a result of which they have the same central axis 5 .

Furthermore, a guide disk 10 is provided on the first tension or compression component 2 in order to guide the first tension or compression component 2 in the second tension or compression component 3 and to jam the first tension or compression component 2 in the second tension or compression component 3 to prevent.

3 shows a plasticizing unit 11 in the assembled state on a shaping machine 25, where in the upper part of the 3 the plasticizing unit 11 is pressed against a closing unit 24 (by means of a contact pressure) and in the lower part of the 3 the plasticizing unit 11 is lifted off the closing unit 24 by a distance L by changing the length of the pull or push rods 1, 20.

The plasticizing unit 11 shown has a plasticizing cylinder 12 with an injection nozzle 17 . The plasticizing unit 11 is held on the closing unit 24 by a first pull or push rod 1 and a second pull or push rod 20, which pull or push rods 1, 20 have a first pull or push component 2 and a connecting device 4 with the first tensile or compressive component 2 connected second tensile or compressive component 3 have. In the embodiment of 3 is the first pull or push rod 1 and the second pull or push rod 20 (according to 1a until 2 B ) identical in construction.

In this exemplary embodiment, the closing unit 24 is formed by a fixed mold mounting plate 13 and a movable mold mounting plate 15, which movable mold mounting plate 15 is guided and movable by bars 16 relative to the fixed mold mounting plate 13. A mold half 14 is arranged on the side of the fixed platen 13 facing away from the plasticizing unit 11, against which the injection nozzle 17 of the plasticizing unit 11 is pressed during the injection process (by a contact pressure).

In the 3 It can be clearly seen how a plasticizing unit 11 can be moved by a distance L relative to the closing unit 24 by a plasticizing unit 11, more precisely by changing the length of the pull or push rods 1, 20.

How a plasticizing unit 11 can be moved by a distance L with the help of the piston-cylinder unit 18, 19 of the plasticizing unit 11, the piston-cylinder unit 18, 19 of the plasticizing unit 11 having a small stroke, since these are only short-stroke cylinders are provided for the contact pressure, is through the 4a until 4e explained.

So is in 4a It can be seen how a first piston-cylinder unit 18 associated with the first pull or push rod 1 and a second piston-cylinder unit 19 associated with the second pull or push rod 20 is supplied with a pressure medium (as illustrated by the arrows) in order to Exposing the plasticizing unit 11, more precisely the plasticizing cylinder 12 with its injection nozzle 17, to a contact pressure, the pull or push rods 1, 20 being subjected to a tensile force. The first pull or push rod 1 has a first pull or push component 2 and a second pull or push component 3 connected to it by the connecting device 4 . The second pull or push rod 20 also has a first pull or push component 21 and a second pull or push component 22 connected to it by a connecting device 23 .

In order to establish a distance L as quickly and effectively as possible, the connecting device 23 of the second pull or push rod 20 is released in a first method step, as in 4b is shown.

Then the first piston-cylinder unit 18 is supplied with a pressure medium (as indicated by the arrow in 4c shown) supplied to eject the first train or pressure component 2 of the first pull or push rod 1. However, the second piston-cylinder unit 19 is held in its position, which means that the first tension or compression component 21 of the second tension or compression rod 20 is separated from the second tension or compression component 22 of the second tension or compression rod 20 is undressed.

In a next step (through 4d shown) the connecting device 23 of the second pull or push rod 20 is closed again and the connecting device 4 of the first pull or push rod 1 is opened.

After opening the connecting device 4 (through 4e shown) is in turn fed to a pressure medium of the second piston-cylinder unit 19, whereby the first train or pressure component 21 of the second pull or push rod 20 is pushed out of the second piston-cylinder unit 19, which means that the distance between plasticizing unit 11 and fixed platen 13 is increased. Due to this increase in the distance between the plasticizing unit 11 and the fixed mold mounting plate 13 and the released connecting device 4, the first tension or compression component 2 of the first tension or compression rod 1 is pulled out of the second tension or compression component 3 of the first tension or compression rod 1. Furthermore, a pressure medium is fed synchronously to the first piston-cylinder unit 18, as a result of which the first tension or compression component 2 is drawn into the first piston-cylinder unit 18 and thus the first tension or compression component 2 of the first tension or compression rod 1 is also pulled out of the second train or pressure component 3.

As the next step in the process, the connecting device 23 of the second push or pull rod 20 is opened and the conn formation device 4 of the first pull or push rod 1 closed, as shown by 4f is shown.

In the next step (as through the 4g shown) the first piston-cylinder unit 18 is again supplied with a pressure medium (as shown by the arrows) in order to push the first pull or push component 2 of the first pull or push rod 1 out of the piston-cylinder unit 18, which in turn results in the first tension or compression component 21 of the second piston-cylinder unit 20 being pulled out of the second tension or compression component 22 of the second tension or compression rod 20 . In addition, the second piston-cylinder unit 19 is supplied with a pressure medium, with the result that the first tension or compression component 21 of the second tension or compression rod 20 is pulled out of the second tension or compression component 22 of the tension or compression rod 20 .

In the next step (through 4 hours shown), the connecting device 23 is closed and the connecting device 4 is opened.

In a final step (by 4i shown) is now the second piston-cylinder unit 19 supplied with a pressure medium, whereby the first train or pressure component 21 of the second pull or push rod 20 is pushed out of the plasticizing unit 11. This in turn pushes the first tension or compression component 2 of the first tension or compression rod 1 out of the second tension or compression component 3 of the first tension or compression rod 1 . In this last method step, the first piston-cylinder unit 18 and the second piston-cylinder unit 19 are also placed in a synchronous initial situation.

5a until 6b show another embodiment of a molding machine 25 according to the invention, wherein the fixed platen 13 can be moved by the pull or push rods 1, 2 as part of an express lifting device relative to the movable platen 15.

By adjusting the position of the first tension or compression components 2, 21 of the tension or compression rods 1, 20 relative to the second tension or compression components 3, 22, an installation height X of the mold (consisting of two mold halves 14) can be taken into account.

The second train or pressure components 3, 22 are formed in this embodiment as part of the piston-cylinder units 18, 19, with the piston-cylinder units 18, 19 and the pull or push rods 1, 2, the rapid lifting device of the shaping machine 25 is realized.

5a shows the embodiment in a closed state with a lower installation height X of the mold and 5b the embodiment in an open state.

6a shows the embodiment of 5a with a mounted mold having a larger installation height X in a closed state. 6b shows again the embodiment of 6a in an open state.
