Description

Turning module for an injection molding machine

The present invention relates to a turning module for an injection molding machine according to the preamble of claim 1, an injection molding machine with a turning module according to claim 9 and a method for producing a molding according to the preamble of claim 16.

A turning module generally refers to the part of an injection molding machine by means of which different molding tools can be formed in a single injection molding machine. An injection molding machine generally has a plurality of tool platens, on which one or more mold halves can be arranged. On the turning module are in turn also a plurality of mold halves, which form molds together with the mold halves of the platens. By a turning module now different mold halves of a single mold half can be assigned to one of the mold platens, whereby in the same injection molding machine different molds can be formed. In this way, for example, the production of a molding of two components is possible.

An injection molding machine with such a turning module is known from DE 101 38 087 A1. The injection molding machine shown there has two tool platens, on each of which a mold half is arranged. Between the tool platens a so-called insert is arranged as a turning module. This insert is rotatable about a vertical axis and has on two opposite sides in each case a mold half. Due to the rotatability of the insert, each of the mold halves disposed on the insert can be associated with each of the mold halves disposed on the platens. From this document Furthermore, a Sphtzgießmaschine is known, in which the turning module is formed by a cube device. The cube device has four mold halves, which are each arranged on a separate cube surface. By means of the cube means, each of the mold halves on the cube means can be associated with each of the mold halves on the mold platens. If one of the disclosed injection molding machines is operated in the 2K mode, in which molded parts are produced from two components, then the first component can be injected simultaneously for one molded part, while the second component for a second molded part is injected to the first component, however In this way, only one molding is made at a time. In addition, the production of molded parts with more than two components is not possible.

From EP 1 810 81 1 A1 an injection molding machine is known, which has both a turning plate and a cube device. In this case, a first plastic part is injected in a mold with a mold half on the insert, then the insert is rotated, whereby a mold is formed by a mold half on the insert and a mold half on the cube device. In this mold then the second plastic component is injected to the first plastic part. In this injection molding machine, too, production is limited to molded parts made of two plastic components, since preparation processes (cutting, venting, cleaning, etc.) take place in the respective cavity on the other surfaces of the cube device.

It is therefore an object of the invention to shorten the production processes of injection molding machines and to make injection molding machines more economical, wherein as far as possible the production variability should not be reduced and preferably even increased.

It is a further object of the invention to enable a simple and economical production of molded parts from more than two components, in particular plastic components. These objects are achieved by a turning module for an injection molding machine according to claim 1, by an injection molding machine with a turning module according to claim 9, and by a method of manufacturing a molding by injection molding according to claim 16.

Advantageous developments are the subject of the respective subclaims.

The turning module according to the invention has a changing device with at least two alternating surfaces. In this context, an exchangeable surface is understood to mean a surface which can be assigned to one or more mold platens, which makes it possible to form molds. The changing device is rotatable about at least a first axis of rotation, wherein this first axis of rotation is preferably arranged substantially vertically. The turning module according to the invention is characterized in particular by the fact that a rotating device is arranged on at least one change surface, which is rotatable about a second axis of rotation.

The turning module according to the invention or parts of this module are thus rotatable about two axes in space. This makes it possible that a production of a molding of two components without an assignment of the change surfaces to both platen is possible. The rotation of the changing device about the first axis of rotation can be used to spend a finished molded part in a Auswerfstellung, whereby, for example, only a rotation of the changing device is necessary by 90 ° about the first axis of rotation. In this way, two moldings can be made from two plastic components at the same time, wherein the two moldings can also be made of different two components.

While the first axis of rotation is preferably arranged substantially vertically, the second axis of rotation is preferably horizontal. The first and the second Rotational axes are preferably orthogonal to each other. In this way, a variety of possible arrangements of the mold halves is given.

Preferably, at least one first mold half is arranged on at least one rotating device. As the first mold halves, the mold halves are referred to in the invention, which are arranged on the turning module and can form a mold with second mold halves. If a plurality of first mold halves are present, they may however be designed differently among one another and in particular have differently configured cavities. The same applies accordingly to the group of second mold halves. In the context of the invention, a molding tool is always formed when two molding tool halves are assigned to one another or facing each other. After the assignment, the mold is then in an open position and can be closed by moving the mold halves towards each other, thereby forming a total cavity.

In an advantageous embodiment of the invention, the changing device is a reversing plate device or a cube device. In particular, a cube device reduces the processing time in the production of a molded part, while a turning plate usually represents a favorable alternative. In addition, in the case of a cube device, unused mold halves - ie the mold halves which are not part of a mold at a particular time - are available for further process steps, such as for cleaning the cavities.

In order that an injection molding machine equipped with the turning module according to the invention can produce even more economically, it is provided in advantageous developments of the turning module according to the invention that the changing device has three or more, and in particular four, alternating surfaces. In principle, an arbitrarily large number is desirable because in this way always two empty and for injecting plastic available mold halves available are while away from the remaining mold halves, for example, the finished molding or remnants of the plastic components or cool the mold halves. On the other hand, an arbitrarily high number of alternating surfaces with mold halves arranged correspondingly thereon can not be realized since, on the one hand, the module would become too large and, in addition, the manufacturing costs of the reversing module according to the invention would become too high. A number of four alternating surfaces is thus particularly preferred.

In an advantageous development of the turning module according to the invention, a rotating device is arranged in each case on a plurality of the change surfaces, in particular on each of the change surfaces. As a result, several or even all alternating surfaces with the mold halves arranged thereon can be used for the production of a multi-component molded part. In this way, a particularly economical production of such a molded part is possible.

The injection molding machine according to the invention has an inventive turning module according to one of the above embodiments. Preferably, the injection molding machine further comprises a first tool clamping plate and a second tool clamping plate, wherein the interchangeable module is arranged between these two tool mounting plates. At least one of the platens is movable, d. H. that this tool clamping plate can be moved in a closing direction to the other platen. In this case, molds that are formed by mold halves on the turning module and mold halves on the mold clamping plates are closed. At least one second mold half is preferably arranged on the first mold mounting plate and / or on the second mold mounting plate.

In principle, however, the use of the turning module according to the invention is readily possible in injection molding machines of a different type, such as, for example, an injection molding machine with a three-plate clamping unit. In an advantageous development of the injection molding machine according to the invention, the turning module is also moved by the movement of the moving tool clamping plate in the direction of the further tool clamping plate. Alternatively or additionally, a separate drive device for the turning module is possible. Advantageously, the turning module is additionally guided by means of a yoke, whereby a tilting of the turning module is prevented.

In order to enable a smooth flow of the manufacturing process of a molded part, in an advantageous development of the injection molding machine according to the invention, at least one change surface faces a tool clamping plate in a first position and faces away from this tool mounting plate in a second position. As a result, a molding tool is formed in the first position by a first mold half and a second mold half.

The second position of an alternating surface can be, on the one hand, an ejection position, in which the molded part is removed from the mold half. However, the second position may also be a position in which the change surface faces another mold half. In this case, a forming tool is again formed there as well. The transfer of the change surfaces from one position to another position is effected by a rotation about the first axis of rotation. In a rotation about the second axis of rotation, the changing surface remains in the same position, it changes only the position of the mold half or mold halves, which are arranged on the rotating device. Advantageously, a first mold half may be associated with at least a plurality of second mold halves by rotation of the rotator and / or rotation of the changer. Equally advantageously, at least one second mold half can be associated with at least a plurality of first mold halves by rotation of the rotator and / or rotation of the changer. As a result, the possibility of a simple variation of the molds is possible. Depending on how many tool halves of the respective other type can be assigned a first or second mold halves, the number of components from which a molded part can be made determined. If, for example, a single first mold half can be assigned to four mold halves in succession, a mold part can be produced from four components, with the individual components being processed one after the other in the formed molds.

The method according to the invention for producing a molded part comprises a conventional injection molding process, in which at least one plastic component is introduced into a mold in the liquid state and solidified there, whereby the molded part is formed. In the method according to the invention, while the method is being carried out, the molded part is moved at least once by means of a changing device about a first axis of rotation of the changing device, whereby the molded part is moved, for example, from a position in which two mold halves form a molding tool into a position in which the molded part can be removed from one of the mold halves, is moved. The inventive method is characterized in particular by the fact that the molding is also at least once by means of a rotating device is moved about a second axis of rotation of the rotating device, wherein both movements are performed on a single turning module. The term molded part is also the half-finished components referred to, for example, at certain times in a production of a multi-component molding, d. H. for example, as an intermediate of only one component, are present. Preferably, the two movements are performed about the first axis of rotation and the second axis of rotation on a single turning module according to the invention according to one of the above embodiments.

In an advantageous development of the method according to the invention, the first axis of rotation is orthogonal to the second axis of rotation. This enables an economical production of the molded parts since, for example, at one time a molded part is injection-molded and another, produced in a preceding cycle, is produced simultaneously. placed molding, which has been moved by a rotation about one of the axes of rotation away, can be removed from a mold half.

Preferably, the first axis of rotation is a vertical axis of rotation, ie a vertical axis, and more preferably the second axis of rotation is a horizontal axis of rotation. This allows easy orientation and a simple transportation of the molded parts in space, which can also reduce the manufacturing cost.

The turning module according to the invention can be installed both as a fixed part of an injection molding machine and designed as a retrofit module. In a training as a retrofit module, the turning module according to the invention is arranged in an existing injection molding machine between two platens and also moved there by the movement of one of the platens. This makes it possible to produce simple molded parts from only one component and additionally by the retrofittable turning module mehrkomponentige moldings with an injection molding machine.

The supply of the components to the cavities can be carried out according to the invention via the tool platens and / or the turning module. This increases the design freedom of the molded parts, since individual components can be injected both from one side and from the opposite side to an already semi-finished or semi-finished molded part.

The invention will be illustrated by way of example with reference to seven figures and exemplified. It shows:

FIG. 2 shows a further embodiment of an injection molding machine according to the invention; FIG. 3 is a schematic representation of a first embodiment of the group of turning modules and tool clamping plates;

Figure 7: schematically a fifth embodiment of the group of turning module and platens.

FIG. 1 shows an injection molding machine 10 according to the invention with a turning module 1 according to the invention. The injection molding machine 10 has a two-plate closing unit with a fixed first platen 2 and a movable second platen 3. The movable platen 3 can be moved by means of a first drive means 8, guided by columns 14, on the fixed platen 2. In this way, the closing unit and formed at this time molds are closed.

The turning module 1 is movable in this closing direction. In this embodiment of the injection molding machine 10 according to the invention, the turning module 1 is moved toward the fixed tool clamping plate 2 via a second drive device 13 during the closing movement of the closing unit. In the closed state, the fixed platen 2, the turning module 1 and the movable platen 3 are in direct contact with each other, wherein a closing force is applied, which ensures a secure closing educated molding tools. The turning module 1 has a changing device 4, which is rotatable about a first axis of rotation z. The changing device 4 has two alternating surfaces 5, 6, which are arranged on opposite sides of the changing device 4. The change surface 5 is in the Fig. 1, which thus represents a specific operating state of the injection molding machine 10, associated with the fixed platen 2. The changing surface 6 is associated with the movable platen 3. Both on the tool platens 2, 3 and on the alternating surfaces 5, 6 mold halves (not shown) can be arranged, which then form when properly used by the assignment of an alternating surface 5, 6 to the first platen 2 and / or the second platen 3 molds , These are closed during the closing movement of the closing unit and thereby form cavities into which plastic material can subsequently be introduced.

The rotatability of the changing device 4 about the first axis of rotation z, which is a vertical axis, makes it possible, the change surfaces 5, 6 from the position shown in Fig. 1, in which the one change surface 5 of the fixed platen

2 and the second change surface 6 of the movable platen 3 is assigned to move away. Thus, it is possible by a rotation of the changing device 4 by 180 °, the change surface 5 of the movable platen

3 and the change surface 6 to assign the fixed platen 2. It is also possible, by rotation from the position shown in Fig. 1 by 90 °, the change surfaces 5, 6 none of the tool platens 2, 3 assign, but to move the change surfaces 5, 6 in a position in the example sprayed parts , which are located in mold halves on the alternating surfaces 5, 6, refer to.

In the embodiment of the injection molding machine 10 shown in FIG. 1, a rotating device 9 is arranged on both alternating surfaces 5, 6, which is rotatable about a second axis of rotation y, which is orthogonal to the first axis of rotation z. In the position shown in Fig. 1, the second axis of rotation y is parallel to Closing direction of the closing unit. If, during normal use, a rotation of the changing device 4 takes place about the first axis of rotation z, then the second axis of rotation y also rotates accordingly. In the position in which, for example, molded parts can be removed from mold halves, the second axis of rotation y is both orthogonal to the first axis of rotation z and to the closing direction of the closing unit.

By means of the turning means 9, it is now possible to perform a change in the allocation of mold halves arranged on one of the alternating surfaces 5, 6, without or in combination with a rotation of the changer 4 about the first axis of rotation z. In this way, for example, opens up the possibility, on a rotating device 9, for example, on the rotating device 9, which is arranged on the change surface 5, to arrange several mold halves, which alone by a rotation of the rotator 9 about the second axis of rotation y alternately a single mold half on the solid Assign tool clamping plate 2. The various possibilities for configuring the arrangement of mold halves are shown specifically in FIGS. 3 to 7. Already from Fig. 1, however, it is clear that the multiple rotatability of the turning module 1 or of components of the turning module 1, for example, the production of a two-component molding is significantly simplified because one or more of such moldings can be made on both sides of the turning module 1 simultaneously , As a result, the efficiency of injection molding machines is significantly increased.

The changing device 4 of the embodiment of the injection molding machine 10 shown in FIG. 1 is designed as a reversing plate device. The insert device and thus the entire turning module 1 is guided by means of a yoke 15, which results in that the turning module 1 does not tilt during a closing and / or opening movement and thus secure closure of the closing unit and of the forming tools is ensured. FIG. 2 shows a further embodiment of the injection molding machine 10 according to the invention. This injection molding machine 10 also has a turning module 1 with a changing device 4. The changing device 4 is formed in this embodiment as a cube device. The turning module 1 is guided only at the foot in this embodiment, but is also moved by a second drive means 13 in or against the closing direction of the closing unit.

Also in this embodiment, the changing device 4 has two alternating surfaces 5, 6, on each of which a rotating device 9 is arranged. The changing device 4 is rotatable about a vertical first axis of rotation z, while the rotary devices 9 are rotatable about a second rotational axis y orthogonal thereto.

FIGS. 3 to 7 describe various possibilities of arranging rotary devices 9 as well as mold halves on the turning module 1 or its alternating surfaces 5, 6, 7. These figures show in each case schematically and partially the assembly of turning module 1 and tool platens 2, 3. Other components of an injection molding machine have been omitted here. Mold halves, which are arranged on the turning module 1 are referred to in Figures 3 to 7 as the first mold halves and to distinguish them from each other with different reference numerals 1 1 -1, 1 1 -2, ... provided. The same applies to the mold halves, which are arranged on the tool platens 2, 3, which are referred to as second mold halves with reference numerals 12-1, 12-2, .... However, this does not necessarily mean that mold halves with different reference numbers differ from the structure.

The turning module 1 according to FIG. 3 has two alternating surfaces 5, 6, which are arranged on a changing device 4. The changing device 4 is rotatable about a first axis of rotation z, whereby the alternating surfaces 5, 6 of the first platen 2 and the second platen 3 can be assigned alternately. On the changing surface 5 a rotating device 9 is arranged. On this rotator 9 is a first mold half 1 1 -1. On the second change surface 6 is a first mold half 1 1 -2, which is located directly on the turning module 1 and 9 without rotating device there. On the first platen 2, two second mold halves 12-1 and 12-2 are arranged. On the second platen 3, a second mold half 12-3 is arranged.

When used as intended, in the position shown in FIG. 3, a mold is formed by the first mold half 1 1 and the second mold half 12-1, and a second mold is formed by the first mold half 1 1 -2 and the second mold half 12-3. By closing the closing unit and thus moving the first platen 2 and the second platen 3 together these molds are closed, whereby a molding can be injected in the cavities formed therein. After this sub-process is completed, the closing unit can be opened again, whereby the molds are opened.

Subsequently, by rotation of the rotary device 9 about the second axis of rotation y, the first mold half 1 1 -1 of the second mold half 12-2 be assigned, wherein the already molded molding remains in the first mold half 1 1 -1. The cavity of the second mold half 12-2 is larger than the cavity of the second mold half 12-1, whereby a second component can be introduced into the additional volume in a subsequent partial process. For this purpose, the now formed by the first mold half 1 1 -1 and the second mold half 12-2 forming mold with the entire closing unit is closed. In the mold halves 1 1 -2 and 12-3, for example, a further molded part can be injected during this time, when the first molded part has already been removed from one of the mold halves.

For example, however, it is also possible that due to the size of the molding of this mold this molding must cool longer, so that in this Time a second component in the mold, formed from the mold halves 1 1 -1 and 12-2, can be injected. Subsequently, after the closing unit has been opened, a rotation about the first axis of rotation z can be made by means of the changing device 4, as a result of which the shaped parts can be removed, for example, from the first mold halves 1 1 -1 and 1 1 -2.

In the embodiment according to FIG. 4, the turning module 1 has two alternating surfaces 5, 6, wherein a rotating device 9 is arranged on the alternating surface 5. On the rotating device 9 is a first mold half 1 1 -1. On the changing surface 6 no rotating device 9 and no mold half is arranged. On the first platen 2, two second mold halves 12-1, 12-2 are arranged. On the second platen 3 is a second mold half 12-3. This embodiment makes it possible to produce a molded part with three components.

When used as intended, the closing unit is closed in the position shown in Fig. 4, whereby in the mold, which is formed from the first mold half 1 1 -1 and the second mold half 12-1, molded a molding. Subsequently, the closing unit is at least partially opened and the rotating device 9 is rotated about the second axis of rotation y, whereby the first mold half 1 1 -1 of the second mold half 12-2 is assigned to the first platen 2. This second mold half 12-2 again has a larger cavity than the second mold half 12-1. By re-closing the closing unit, a mold is formed from the first mold half 1 1 -1 and the second mold half 12-2 closed, so that a second component can be molded onto the existing mold part.

Subsequently, the closing unit is opened again, whereby the mold is opened, wherein the now two-component molding remains again in the first mold half 1 1 -1. Subsequently, the bill of exchange tion 4 about the first axis of rotation z and the rotary device 9 about the second axis of rotation y rotated by 180 °, whereby the first mold half 1 1 -1 of the second mold half 12-3 is assigned and forms a mold with this. The second mold half 12-3 has a cavity that is larger than that of the second mold half 12-2 or that leaves at least one void when the now formed mold closes. In this space now a third component can be injected, which is thus molded onto the two-component molding, whereby a molding of three components can be produced. Subsequently, after opening the closing unit, the changing device 4 can be rotated into an ejection position. Finally, the changing device can be moved back into the position shown in Fig. 4 and the manufacturing process can start again.

In Fig. 5, a further embodiment is shown, in which the turning module 1 has two alternating surfaces 5, 6, on each of which a rotating device 9 is arranged. On each of the rotating devices 9 are two first mold halves, so a total of four mold halves 1 1 -1, 1 1 -2, 1 1 -3 and 1 1 -4 arranged. On the first platen 2 are two second mold halves 12-1 and 12-2. On the second platen 3 are also two second mold halves 12-3 and 12-4. The first mold halves 1 1 -1, 1 1 -2, 1 1 -3 and 1 1 -4 are all identical. The second mold halves 12-1 and 12-3 are also identical, as are the second mold halves 12-2 and 12-4. The second mold halves 12-2 and 12-4 have a larger cavity than the second mold halves 12-1 and 12-3.

By this embodiment, a particularly economical production of two-component moldings is possible. First, the closing unit and the formed molds are closed and it can be molded in the molds, which are formed from the mold halves 1 1 -1 and 12-1 and 1 1 -3 and 12-3, a molded part of a first component. Subsequently, the closing unit is opened and the rotating means 9 are at the second Rotary axis y turned. Thereafter, the closing unit is closed again, whereby in the mold, formed from the mold halves 1 1 -1 and 12-2 or 1 1 -3 and 12-4, a second component can be molded onto the previously molded molding. At the same time in the molds, formed from the mold halves 1 1 -2 and 12-1 or 1 1 -4 and 12-3, another molded part can be injected from a first component. After the subsequent opening of the closing unit, the molded parts can be removed from two components, whereby the first mold halves 1 1 -1 and 1 1 -3 are again empty, so have no molding in it. To remove the moldings, the changing device 4 is rotated by 90 °, so that a simple removal is possible.

Subsequently, the rotating means 9 can be rotated again, whereby in principle the initial position of Fig. 5 again sets, wherein additionally in the first mold halves 1 1 -2 and 1 1 -4 a one-component molded part is arranged. After the subsequent closing of the closing unit, the second component can be injection-molded onto this molded part, while at the same time a molding of one component is injected in the two other molding tools. Thus, two two-component moldings can be injected simultaneously, whereby the production costs can be lowered and thus the efficiency of the injection molding machine can be increased.

In the embodiment according to FIG. 6, the turning module 1 has on the change surface 5 a rotating device 9 on which two first mold halves 1 1 -1, 1 1 -2 are arranged. The arranged on the change surface 6 mold halves are not shown here. The same applies to the mold halves of the second platen 3. On the first platen 2, a second mold half 12-1 is arranged, which forms a mold with the first mold half 1 1 -1 in the position shown in Fig. 6. After closing the closing unit, a molded part can be injected from a component in this mold. After the subsequent opening of the closing unit, the rotary device 9 is rotated about the second axis of rotation y, whereby the first mold half 1 1 -2 of the second mold half 12-1 is assigned. When opening the closing unit, the molding remains in this embodiment in the second mold half 12-1. The first mold half 1 1 -2 has a larger cavity than the first mold half 1 1 -1, whereby during the subsequent closing of the closing unit a cavity remains, which can be filled by a second component, which is thus molded onto the first component. This component may, for example, merely be a coating which can not be introduced into the cavity via an extrusion screw but via a simple hydraulic line. The supply of the coating material takes place via the turning module. 1 After the subsequent opening of the closing unit, the changing device 4 can be rotated by 90 °, whereby the remaining in the first mold half 1 1 -2 -2 molded part is in a position in which it can be removed from the mold half.

In the embodiment according to FIG. 7, the changing device 4 is formed from a cube device which has four alternating surfaces, three of which can be seen, namely the alternating surfaces 5, 6, 7. On each of these alternating surfaces 5, 6, 7 is a rotating device 9 arranged with two first mold halves. In Fig. 7 are thus on the three alternating surfaces 5, 6, 7 a total of six first mold halves 1 1 -1, 1 1 -2, 1 1 -3, 1 1 -4, 1 1 -5, 1 1 -6 arranged. On the two tool platens 2, 3 two second mold halves are arranged in each case. With this embodiment, the production of molded parts from four components is possible. In the following, the manufacturing process of a molded article will be described. First, in the mold, which is formed from the first mold half 1 1 -1 and the second mold half 12-1, molded part molded from a component.

After opening the closing unit, the rotating device 9, on which the first mold half 1 1 -1 is arranged, rotated about the second axis of rotation y, so that subsequently with the aid of the second mold half 12-2, a second Component can be molded onto the molding. During the subsequent opening of the closing unit, the molded part remains in the first mold half 1 1 -1. The changing device 4 is then moved or rotated about the first axis of rotation z. It is possible that the changing device 4 is first rotated by 90 °, wherein in the mold half 1 1 -3 another molding of two components is injected.

After a renewed opening of the closing unit, the changing device 4 can be rotated again by 90 °, whereby the first mold half 1 1 -1 of the second mold half 12-3 is assigned to the second platen 3. With this assignment, a third component can then be injected onto the molded part. After a subsequent opening of the closing unit and a rotation of the rotating device 9 with the first mold half 1 1 -1 can then be molded by means of the second mold half 12-4, a fourth component to the molding.

The manufacturing process described above relates only to a molded part. However, it is also possible that during the production of this molded part in the first mold half 1 1 -1 another molding in the first mold half 1 1 -2 is prepared, which also by a rotation of the rotator 9 about the second axis of rotation y each first one and then the other mold half can be assigned to one of the mold platens.

Alternatively, it would also be possible to design the second mold halves 12-1 and 12-3 as well as 12-2 and 12-4 identical to one another in each case. As a result, the production of four-component moldings would no longer be possible, but this can be realized by a double production of molded parts of two components. LIST OF REFERENCE NUMBERS
