Description

Mold with adjustable mandrel

The invention relates to a mold, in particular an injection mold, for the production of moldings, such as hollow plastic, in which a mold core by means of an adjusting device relative to an outer mold is displaceable, as described in claim 1.

It has heretofore been known to guide mold cores of molding tools in a cast-iron core guide, wherein the actuator designed in the form of a cylinder-piston arrangement is arranged on the side of the cast-iron core guide which is remote from the outer mold. The effective tensile force of the actuator is aligned with the longitudinal axis of the mandrel, wherein the piston rod is coupled to the mandrel. The disadvantage here are the great length of the entire actuator and the lower tensile force for the adjustment of the mandrel away from the outer shape.

An injection molding machine with adjustable via a cylinder piston assembly mandrels has become known from JP 05-104583 A. In this case, laterally and radially offset from the mold core arranged cylinders are provided which are supported on a molded part such that the larger piston area of the cylinder is acted upon in carrying out the lifting movement with the pressure medium. Between the two cylinders another cylinder is arranged, which can be brought into connection with the mold core. With this adjusting device can be spent on the central cylinder of the mold core in a preheating, which can be adjusted with its laterally arranged cylinders of the mold core between its working position and release position.

Another adjusting unit for a mandrel has become known from JP 10-100162. The adjusting unit comprises a guide carriage on which the mold core is held. Furthermore, the guide s pour over a laterally and radially offset to the mold core axis cylinder-piston assembly can be adjusted in a guide assembly between a working position and a release position. In addition, the mold core can also be adjusted relative to the guide carriage via a further cylinder-piston arrangement. Here is for the implementation of the adjustment of the working position in the release position, however, the smaller piston area available. The disadvantage here is the overall te length and the lower available force of the adjusting cylinder due to the smaller piston area.

Other adjusting devices for mandrels have also become known from US 2008/0257520 AI and FR 2 817 793 A.

Furthermore, among other things, the opening movement of the molds was used to perform this additional adjustment movement of the mandrel relative to a molding of the molds.

The present invention has for its object to minimize the dimensions, in particular the overall length, the adjusting device for the mandrel and in addition to increase the tensile force for the adjustment movement of the mandrel away from the outer mold. This object of the invention is solved by the features of claim 1.

The resulting from the features of claim 1 advantage is that by installing the cylinder-piston assembly, the piston rod performs a directed on the side facing away from the outer side movement for the adjustment of the working position towards the release position. Thus, a lesser projection of the adjusting device over the outer shape is achieved in the retracted state and located in the working position of the mold core. Furthermore, such a coupling or connection of the laterally arranged with respect to the mold core to be adjusted drive member is achieved with the mold core. Thus, a power transmission is created starting from the drive member to the mandrel. It is also advantageous that in a simple manner a safe power transmission for the adjustment can be created in a small footprint. In addition, the overall length of such core pullers can be shortened compared to previously known arrangements by the lateral arrangement of the drive member of the adjusting device with respect to the mold core to be adjusted. Thus, the drive member is arranged adjacent to the mandrel, so that it extends outside the cross section of the mandrel and so does not protrude into the space required by the mandrel during its adjustment between the working position and the release position. Thus, the possibility is created to be able to use smaller cylinder-piston arrangements, since with identical When pressing the pressure medium, the larger piston area is available for pressure application. Furthermore, for example, even labor-intensive and therefore expensive special designs of protective grid extensions can be avoided in systems for producing the molded bodies, as is the case with injection molding machines. In addition, however, the disassembly of components, such as, for example, the drive member, can be prevented during installation of the mold core, as a result of which shorter set-up or conversion times can be achieved in the overall system. This achieves a more economical process with increased productivity. Especially with long Kernzugbewegungen mechanical core pulls, in which they are coupled to the opening movement of the outer mold, are difficult to implement and so the additional arrangement of a separate actuator is necessary. Furthermore, but also the installation of the adjusting device, in particular of the associated mold core, can be significantly facilitated. In addition, however, a protective grid spacing on the production machine can be selected smaller than previously. By minimizing the space required for each production plant, such as an injection molding machine, even better space utilization can be achieved. Thus, a higher degree of density of individual production plants can be achieved on the same available footprint.

Also advantageous is a further embodiment according to claim 2, because characterized an exact axial adjustment of the mandrel can be made with respect to the longitudinal axis defined by the mold cavity. If, however, the longitudinal orientation of the drive member is optionally associated with a likewise angular orientation of the longitudinal guide elements with respect to the longitudinal axis of the mold cavity, a lifting movement of the mold core from the cavity of the outer mold, in particular one of the mold parts, can take place after opening the moldings of the outer mold. This is advantageous if the sealing takes place over a larger area and would thereby rub together otherwise cooperating sealing surfaces during the opening movement. This can be prevented by the slight lateral or eccentric displacement of the mold core with respect to one of the mold parts of the outer mold. Furthermore, it also reduces the friction of these interacting components and thus also minimizes the applied adjusting force of the drive member. In addition, damage to the cooperating Formbzw. Sealing surfaces of the mold are avoided, which are referred to as so-called Reiber. In the embodiment according to claim 3 is advantageous that the Auslangen can be found with a small footprint and still a secure, mechanical coupling or connection and thus transmission of the adjusting can be done starting from the drive member towards the mandrel.

Through the development according to claim 4 it is achieved that an exact longitudinal guide is created within the adjusting device so as to avoid damage during the adjustment movement of the mandrel relative to the outer mold. Due to the design according to claim 5, the mandrel can be performed over its entire displacement exactly in the longitudinal guide element.

An embodiment according to claim 6 is also advantageous since, as of the beginning of the adjustment movement, a high overlap length is achieved between the guide part and the guideway receiving it. As a result, high torques and transverse forces occurring precisely at the beginning of the adjustment movement can be transmitted better without there being any jamming during the adjustment movement.

According to one embodiment, as described in claim 7, a high overlap length is created with the cooperating guide assembly so even for the control element at the beginning of the adjustment, whereby the moments and lateral forces occurring can be better absorbed and removed.

In this case, an embodiment according to claim 8 proves advantageous, because thereby a separate, exact guidance of the mold core can be achieved during its adjustment movement. In addition, the possibility is created to be able to perform additional positioning movements of individual tool parts of the mandrel on the separately movable actuator independently of the movement of the mandrel. According to an advantageous embodiment according to claim 9, an additional possibility is created to be able to perform the mold core even more precisely during its adjustment movements. By the diametrical arrangement of the other guide elements, which preferably in the mold parting plane are arranged, an even more accurate longitudinal guidance of the mandrel can be achieved here.

However, an embodiment according to claim 10 is also advantageous since a simple fastening possibility and the associated guiding accuracy of the mold core can be achieved relative to the longitudinal guide element (s).

According to claim 11, an additional support and absorption of forces, which are introduced by the eccentric arrangement of the drive member relative to the longitudinal axis, achieved. As a result, a stable structural unit can be created in cooperation with the longitudinal guide elements, which despite their shortened length and eccentric arrangement allows an exact adjustment.

In the embodiment according to claim 12, an even more stable and easy to be formed adjusting device is thus created, with which an exact longitudinal adjustment of the mandrel is feasible.

It is also possible training according to claim 13, because so in the smallest space a stable mounting of the drive member can be ensured.

Finally, however, an embodiment as described in claim 14, an advantage, since such a storage or support of the cylinder can take place on a molded part of the outer mold, which due to the lateral arrangement of the cylinder with respect to the mandrel axis or the Kavitätsachse a allows some freedom for the automatic Lageein- position of the cylinder due to moments. Thus, the cylinder retains a certain degree of freedom during the adjustment movement of the mold core so as not to introduce any additional moments into the adjusting device.

Furthermore, it is advantageous if a cylinder of the cylinder-piston assembly is connected to the mold core and the piston rod end of the piston rod to the outer mold. This embodiment also allows an eccentric arrangement of the drive member with respect to the longitudinal axis of the mold cavity, in which for the adjustment of the larger Piston surface is available for loading with the pressure medium. This can in turn be found with smaller sizes Auslangen.

Finally, it would also be possible for the drive member to be formed by a spindle drive encompassing a threaded spindle and a cooperating spindle nut, the spindle nut being connected to the mold core. Thus, an even shorter adjusting device can be created in which even during the adjusting movement of the mold core no further components protrude beyond the already existing outer contour of the adjusting device. Above all, the length of the entire adjusting device does not change, regardless of whether the mandrel is in the working position or the release position.

By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the position information selected in the description, such as top, bottom, side, etc. are related to the directly described and illustrated figure and are mutatis mutandis transferred to the new location in a change in position. FIGS. 1 to 6 show a first possible and possibly independent embodiment of a molding tool 1, which is used in particular for an injection molding tool or a casting tool, such as a diecasting tool, for the production of shaped bodies (not shown here). These shaped bodies can be, for example, hollow bodies, such as pipes, nozzles, fittings or the like. When working by injection molding, materials such as plastics are used, which are softenable and can be processed by injection molding. If the mold 1 is used as a casting tool, in particular a diecasting tool, it is also possible to use metal alloys, in particular low-melting metal alloys, for producing the shaped bodies.

The molding tool 1 shown here in simplified form comprises an outer mold 2, which consists of at least one, but preferably several molded parts 3, 4. In most cases, two or more mold parts 3, 4 are used and provided for demolding, at least one or more parting planes for demolding of the moldings from the one or more cavities.

In the simplified representation of the outer mold 2, for example, the nozzle-side mold part 3 is fixedly arranged on the injection molding machine, whereas the indicated in dashed lines, further mold part 4 that molding is, which is relative to the first mold part 3 is adjustable. This is well known and will therefore not be discussed in detail. Between the two mold parts 3, 4 is simplified, a mold parting plane with the reference numeral 5 entered. Furthermore, the molding tool 1 also comprises at least one mold core 6, which is displaceable relative to the outer mold 2 between different positions along an adjustment path 7. The adjustment path is usually selected to be straight, with the direction of the adjustment being indicated by a simple arrow. If a different longitudinal course of the adjustment 7 is used for straight-line displacement, the displacement between the positions or positions of the mandrel 6 described below relative to the outer shape 2 takes place along the same. If the mandrel 6 is in a position inserted into the outer mold 2, it is interposed the mold core 6 and the outer mold 2 achieved a closed position of the mold 1 and thereby forms a non-illustrated mold cavity. In these, the prepared for the production of the molding material is introduced. In this case, this position of the mold core 6 can be referred to as a so-called working position. In order to be able to remove the molded article or bodies produced from a molded part 3, 4 of the outer mold 2 after opening the outer mold 2, the at least one mold core 6 can be adjusted from its working position into at least one release position (see FIG. 4). to relocate. During the demoulding of the shaped bodies to be produced, it is also possible to require a plurality of release or intermediate positions, as may be the case, for example, in the case of multi-component injection molding.

In order to be able to form a cavity which is open towards its interior and extending in the direction of the outer wall, if necessary, a plurality of segments arranged one behind the other in the circumferential direction can be provided on the mold core 6 in the region of the cavity of the shaped body to be produced will not be discussed in detail. In this case, these segments have a shaping region which is complementary to the depression to be produced and are adjustable from a position forming a core part at least partially projecting and thereby forming the recess into a release position located within the cross section of the molded core part.

In order to perform this adjustment movement in the course of the opening movement or the adjustment of the mold core 6, a so-called intermediate position is shown in Fig. 3, in which the mandrel 6 is still disposed between the closed mold parts 3, 4 of the outer mold 2, but already a certain, axial adjustment of individual mold core parts to release the segments is done. In order to be able to fix the mold core 6 relatively in the still closed position of the mold parts 3, 4, a groove-shaped recess 8 can be formed or arranged in the region of the outer circumference of the mold core 6. In this recess 8 engages, for example, a non-illustrated approach of the molding 4, whereby an axial locking of the mold core 6 relative to the outer mold 2 is achieved. Thus, the adjustment of individual mold core parts to release the segments can be done without the entire mold core 6 is moved axially. After opening the here formed adjustable molding 4 then the adjustment of the mold core 6 takes place in the release position described above, as shown in FIG. 4.

The previously described mold cavity, which is formed between the mold core 6 and the outer mold 2 in the closed working position, defines a longitudinal axis 9, as is the case, for example, with tubular hollow bodies. In this exemplary embodiment, the longitudinal axis 9 defined by the mold cavity lies in the mold parting plane 5. In order to be able to carry out the adjusting movement of the mold core 6 relative to the outer mold 2, the mold 1 further comprises at least one actuating device 10 with a drive member 11 Drive member 11 is in turn in operative connection with the mold core 6 or is coupled to the mold core 6 in order to be able to displace the mold core 6 along its adjustment path 7 - see arrow - between its different positions or positions relative to the outer mold 2 ,

As can now better be seen from a synopsis of FIGS. 1 and 6, in the working position of the mold core 6, its central axis is arranged in alignment or coaxial with the longitudinal axis 9 of the mold cavity in the outer mold 2. The drive member 11 of the adjusting device 10 is in turn arranged with respect to the longitudinal axis 9 of the mold cavity in the radial direction to distanced. This means that the drive member 11 is arranged laterally with respect to the mold core 6 and the mold parting plane 5.

By this radial or lateral displacement of the drive member 11, it is possible to find the Auslangen with a shorter overall length of the adjusting device 10, as was the case with previously known adjusting devices. Furthermore, it is shown here that a longitudinal orientation of the drive member 11 of the adjusting device 10 with respect to the longitudinal axis 9 of the mold cavity to parallel or approximately parallel selected. In this embodiment of the molding tool 1 shown here, a standing, in particular a vertical orientation of the adjusting device 10 is provided, whereby the entire mold core 6 is to be adjusted away from the outer mold 2 in the opposite direction to the acting gravity. Furthermore, here is the drive member 11 in the embodiment according to FIGS. 1 to 6 formed by a cylinder-piston assembly, which is so coupled to the mandrel 6, that for the adjustment of the mandrel 6 starting from its working position towards his Release position, the larger piston area of the cylinder-piston assembly is acted upon by the pressure medium.

As a result of the above-described radial, lateral displacement of the adjusting device 10, in particular its drive element 11, with respect to the longitudinal axis 9 of the mold cavity of the outer mold 2, the entire adjusting device 10 can also be arranged on one of the molded parts 3, 4 of the outer mold 2 be attached. In the present embodiment, the adjusting device 10 is connected to the molded part 3. As can now better be seen from FIGS. 4 and 5, the cylinder 12 of the cylinder-piston arrangement is held on a component of the adjusting device 10 which will be described in more detail below. A piston rod 13 of the cylinder-piston assembly projects from the cylinder 12 to the side facing away from the outer mold 2 side. For relative adjustment of the mandrel 6 with respect to the outer mold 2, a piston rod end 14 of the piston rod 13 of the cylinder-piston assembly is coupled on its side facing away from the outer mold 2 side with the mandrel 6.

To be able to perform this mutual coupling between the piston rod 13 and the mandrel 6, seen in the radial direction, between the drive member 11 and the longitudinal axis 9 of the mold cavity extending in the direction of Verstellweges 7

Actuator 15 is provided. In a parallel alignment of the longitudinal extent of the adjusting device 10, in particular of the drive member 11 with respect to the longitudinal axis 9 and the adjusting element 15 is aligned parallel to the longitudinal axis 9. The adjusting element 15 has spaced-apart first and second ends 16, 17 in its longitudinal extension, wherein in the present exemplary embodiment the first end 16 is coupled to the mold core 6 and the second end 17 is coupled to the piston rod end 14. Due to the mutually different radial lateral displacement of both the drive member 11 and the actuator 15 with respect to the longitudinal axis 9, the two ends 16, 17 of the actuating element 15 each with the interposition of the first and second coupling s pieces 18, 19 with the mold core 6 and dem Piston rod end 14 coupled. In this case, the two coupling pieces 18, 19 preferably extend transversely, in particular perpendicular with respect to the longitudinal axis 9 of the mold cavity between the piston rod 13 and the adjusting element 15 and the adjusting element 15 and the mandrel 6. The first coupling piece 18 can either directly with the mold core 6, or else be an adjusting means for the previously briefly described, radial adjustment of the individual segments to form the depression in the molding or molding. Regardless, it would also be possible to connect the first end 16 of the actuating element 15 directly and without the interposition of the first coupling piece 18 with the mandrel 6 or to couple.

Furthermore, the adjusting device 10 comprises at least one parallel to the adjustment 7 and the longitudinal orientation of the drive member 11 aligned first longitudinal guide element 20 with at least one guide 21. At or in this at least one guide track 21, a guide member 22 is guided guided. In this case, the longitudinal guide element 20 and the guide part 22 form a guide arrangement.

In order to achieve a certain torsional stability as well as guidance accuracy in the axial direction, it is advantageous to choose two oppositely disposed longitudinal guide elements 20 with mutually facing guideways 21. In this case, the longitudinal guide element 20 may have a guide length which corresponds at least to the extent of the length of the adjustment path 7 of the mold core 6 between its two positions, namely the working position and the release position. The at least one guide part 22 in turn has a longitudinal extent, which likewise corresponds at least to the extent of the length of the adjustment path 7 of the mold core 6 between its two positions. This ensures that a complete overlap of the cooperating guideway or guideways 21 with the guide part or parts 22 is already ensured at the beginning of the adjustment process. This is because, due to the eccentric arrangement of the drive member 11 with respect to the longitudinal axis 9, moments occurring during the adjustment process can be absorbed or removed by the guide arrangement between the longitudinal guide element 20 and the guide part 22. With increasing adjustment of the mold core 6 away from the outer mold 2, the guide length between the guide members 22 and the one or more guide tracks 21 is shorter. In previously known solutions, the adjustable mandrel 6 is moved during its longitudinal adjustment towards its working position so far that held on reaching the end position of the mandrel via clamping ring segments, which can also accommodate the injection pressure. It is disadvantageous that it is due to the imprecise guidance during the adjustment in Contact areas between the mandrel 6 and the molded part 3, 4 can come to rubbers to Kaltverschweißungen. This manifests itself by scoring on these components. In the objective solution this is avoided by the guide arrangement, in particular its guide length. Due to the exact longitudinal guide as an unwanted contact between the relatively adjustable components is avoided. Only at

Closing the mold, the mold core 6 is pressed in its end position in the core bearing or the outer mold forming mold parts 3, 4 and locked by clamping ring segments, not shown. Thus, the injection pressure of the mold cavity forming components is properly recorded.

Preferably, the or the guide parts 22 is arranged on the adjusting element 15 or formed there. The one or more guide members 22 may be formed either as its own components or also form an integral part of the control element 15. Thus, for example, an opposite or diametrically aligned arrangement of the guide members 22 on the actuator 15 done. It should be noted that the cross section of the guide member 22 and the cooperating guide track 21 has been chosen only by way of example for a variety of ways. Thus, this guide arrangement can e.g. be formed by a dovetail guide, a T-slot guide, a spline guide or the like. However, it would also be possible to choose a roller guide, cylinder guide or the like. Likewise, however, any combination of the different previously described and cooperating guide elements is possible. In this case, a use of sliding and / or Wälzführungen is possible.

In order to ensure an exact guidance of the mold core 6 during its adjustment movement, it is advantageous if the mold core 6 is also provided with at least one own guide element 23, as best seen in the representation of FIG. 4. In this case, the guide element 23 may be arranged on the mold core 6 in such a way that this guide element 23 is guided in the guide track or lanes 21 of the at least one longitudinal guide element 20 of the guide arrangement. This separate storage of the mandrel 6 from the actuator 15 is therefore necessary in order to achieve the intermediate position described above during the demolding movement of the mandrel 6 can. If this intermediate position is not required, the actuating element 15 could, without the interposition of the first clutch piece 18 may be connected directly to the mold core 6 and dispense with the arrangement of the guide member 23.

The one or more longitudinal guide element 20 are arranged in this embodiment shown here in the outer peripheral region of the mandrel 6 and arranged spaced from each other in the transverse direction to the adjustment 7. Because the one or more longitudinal guide elements 20 serve to guide the guide part or parts 22 which are arranged on the adjusting element 15, the longitudinal guide elements 20 are also arranged in the radial direction between the drive member 11 and the longitudinal axis 9. In this case, a symmetrical arrangement of the longitudinal guide elements 20 and guide members 22 with respect to a running in the longitudinal axis 9 and aligned in the direction perpendicular to the mold parting plane 5 center plane 24 take place, as simplified in Fig. 6 is shown.

As can further be seen from a combination of FIGS. 1, 4 and 6, the adjusting device 10 further comprises at least one support element 25, which or which is preferably aligned parallel to the first longitudinal guide element 20 of the guide arrangement or the longitudinal orientation of the drive member 11 is or are. The provided in this embodiment, two support members 25 are arranged on the side facing away from the longitudinal axis 9 side of the longitudinal guide member 20 and drive member 11. Due to the off-center to the longitudinal axis 9 applied adjusting force of the drive member 11 and the associated moments here are the support members 25 loaded with a tensile force acting on them during the adjustment of the working position towards the release position. In order to achieve a mutual connection or coupling of the longitudinal guide elements 20 with the support element or elements 25 on the side facing away from the outer mold 2, the abovementioned components can be coupled to one another, for example via a connecting plate 26. Furthermore, it is advantageous if the drive member 11, in particular the cylinder 12 of the cylinder-piston arrangement is held on at least one of the longitudinal guide elements 20 or fastened thereto. This can be done in cooperation with the

Longitudinal guide elements 20 and support members 25 are created a unit which can be made in a corresponding orientation with respect to the adjustment path 7 and the longitudinal axis 9 on the outer mold 2. FIGS. 7 to 10 show a further embodiment of the molding tool 1, which may be independent of itself, wherein the same reference numerals or component designations are used again for the same parts as in the preceding FIGS. 1 to 6. To avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1 to 6 or reference.

In this embodiment of the molding tool 1 shown here is a similar design, as has already been described in detail previously in FIGS. 1 to 6. Therefore, reference is made only to the different configurations and arrangements of individual components of the actuator 10 closer reference. The one shown here

Forming tool 1 likewise comprises in turn the outer mold 2 with its molded parts 3, 4, shown in simplified form, the mold core 6 and the adjusting device 10.

The adjusting device 10 in turn comprises at least one of the longitudinal guide elements 20, here in the present embodiment, two diametrically opposed Längsführungs- elements 20 - between which in turn the actuator 15 with the guide disposed thereon steep 22 in the or the guideways 21 is guided. In order to avoid unnecessary repetition, reference is made to the detailed preceding description for the design and arrangement of the drive member 11, the coupling or connection with the adjusting element 15 with the first and second coupling pieces 18, 19. The mandrel 6 is in turn guided separately over the guide element 23 in the or the guideways 21 of the longitudinal guide element 20. The cylinder 12 of the cylinder-piston assembly is in turn connected to the longitudinal guide elements 20 or held thereto.

In contrast to the embodiment described above, it is provided in this adjusting device 10 that the or the support elements 25 are not arranged on the side facing away from the longitudinal guide elements 20 and the drive member 11 of the longitudinal axis 9 and the mold parting plane 5, but that in However, the mold parting plane 5 are arranged distanced from each other in the transverse direction to the adjustment 7. Thus, these support elements 25 provided here are loaded at the beginning of the adjustment process up to reaching the release position with a compressive force due to the eccentric arrangement of the drive member 11 with respect to the longitudinal axis 9 and the mold parting plane 5. At the end facing away from the outer mold 2, the support element or elements 25 can in turn be connected to one another or the longitudinal guide elements 20 via the connecting plate 26 so as to form a unit and transmit corresponding forces.

FIGS. 11 to 14 show a further embodiment of the molding tool 1, which may be independent of itself, wherein the same reference numerals or component designations are again used for the same parts as in the preceding FIGS. 1 to 10. To avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1 to 10 or reference.

The mold 1 shown here differs from the two previously described embodiments according to FIGS. 1 to 6 and 7 to 10 in that the support elements 25 previously described in FIGS. 7 to 10 in this embodiment shown here additional, further Form longitudinal guide elements 27 of the adjusting device 10. This or these further longitudinal guide elements 27 cooperate with further guide elements 28 arranged on the mold core 6, wherein the further guide elements 28 are arranged diametrically opposite to the mold core 6 on the outside thereof. These further longitudinal guide elements 27 in turn likewise have further guide tracks 29, which extend in a parallel direction with respect to the longitudinal axis 9. In this case, the further guideways 29 and the further longitudinal guide elements 27 in the region of the mold parting plane 5 are arranged at a distance from one another transversely to the longitudinal extent of the adjustment path 7 and preferably connected to the outer mold 2, in particular the molded part 3. In addition to this, it may still be advantageous to guide the mold core 6 with its guide element 23 in the longitudinal guide element (s) 20 so as to achieve a kind of three-point bearing and associated, exact longitudinal guidance of the mold core 6. The storage of the Formkrns 6 on the guide member 23 in the longitudinal guide member 20 is shown in FIGS. 1 to 6 and 7 to 10 and described in detail. In order to avoid unnecessary repetition, reference is made to the disclosure made there or reference is made.

The longitudinal adjustment of the mold core 6 takes place here again by the drive member 11, which is formed by a cylinder-piston assembly. The coupling of the drive element 11 in the region of its piston rod end 14 via the second coupling piece 19 with the adjusting element 15 can be carried out analogously to the embodiments described above. The coupling or the connection of the adjusting element 15 with its first end 16, optionally with the interposition of the first coupling piece 18, can also be carried out analogously to the embodiments described above.

The longitudinal extent of the further longitudinal guide elements 27 and their guide length of the further guideways 29 may also amount to an extent which corresponds at least to the length of the adjustment path of the mandrel 6 between its two positions. Thus, here too the first longitudinal guide elements 20 as well as the further longitudinal guide elements 27 end at an equal distance, starting from the outer mold 2 on the side facing away from this. By providing the additional further guideways 29, the further longitudinal guide element 27 also serves as a support element 25 at the same time in order to be able to pick up and remove the adjusting torques introduced by the eccentric arrangement of the drive member 11. Thus, not only an additional improved guidance of the mandrel 6 is achieved during its axial displacement or displacement, but components saved, since so the further longitudinal guide member 27 assumes a dual function.

FIGS. 15 to 18 show a further embodiment of the molding tool 1, which may be independent of itself, wherein the same reference numerals or component designations are again used for the same parts as in the preceding FIGS. 1 to 14. To avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1 to 14 or reference. Also in this embodiment shown here, the drive member 11 of the adjusting device 10 is also again eccentrically or radially with respect to the longitudinal axis 9 of the mold cavity arranged thereto. In contrast to the embodiments described above, here the cylinder 12 of the drive member 11 is not disposed on one of the longitudinal guide elements 20, but this is coupled or connected to the mandrel 6.

The orientation and arrangement of the drive member 11 formed here by a cylinder-piston assembly takes place such that the piston rod end 14 of the cylinder-piston assembly of the outer mold 2, in particular one of the mold parts 3, 4, is facing. Furthermore, in the present embodiment, the piston rod end 14 with the outer mold 2, in particular with the molded part 3, be coupled.

The guidance of the mold core 6 takes place here, similar to that described in FIGS. 6 to 14, by the diametrically opposite further longitudinal guide elements 27, on which the further guide tracks 29 are arranged or formed. The further longitudinal guide elements 27, in particular their guide tracks 29, are arranged centrally with respect to the mold parting plane 5 and arranged distanced to one another in the transverse direction to the adjustment path 7. Thus, the mold core 6 is again located between the two further longitudinal guide elements 27 and is guided by the further guide elements 28 provided on the mold core 6.

By the coupling of the cylinder 12 with the mold core 6 and its guide to the other longitudinal guide elements 27 is also in the cylinder piston arrangement chosen here, the larger piston surface for the adjustment of the mold core 6, starting from its working position to its release position available. In this case, the piston rod 13 is stationary or fixedly connected to its piston rod end 14 or coupled to the outer mold 2, wherein the cylinder 12 performs the relative displacement upon application of a corresponding pressure medium together with the mold core 6 coupled thereto.

Due to the direct coupling of the cylinder 12 with the mold core 6 can be dispensed with the arrangement of the actuating element 15.

FIGS. 19 to 22 show a further embodiment of the molding tool 1, which may be independent of itself, wherein the same reference numerals or component designations are again used for the same parts as in the preceding FIGS. 1 to 18. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1 to 18 or reference. This embodiment shown here is, in principle, a combination of the embodiments as they have been previously described in FIGS. 1 to 6 and 15 to 18. The mold 1 comprises the outer mold 2, the mold core 6 and the adjusting device 10. The mold core 6 is here provided with diametrically opposite and arranged in the mold parting plane 5 further guide elements 28 which engage in the other guideways 29 of the other longitudinal guide elements 27 and stored guided are. Thus, the axial displacement of the mandrel 6 relative to the outer mold 2 is guided by the interaction of the other guide elements 28 with the further longitudinal guide elements 27 arranged or formed further guideways 29. The longitudinal extension of the other guideways 29 and the other longitudinal guide elements 27 corresponds at least to Extent of the length of the adjustment 7 of the mold core 6 see between its two positions.

The drive member 11 of the adjusting device 10 is not formed here by a cylinder-piston assembly, but by a spindle drive. In the present exemplary embodiment, this spindle drive comprises a threaded spindle 30, which may also be referred to as a so-called motion screw. One of the outer mold 2 facing the end of the threaded spindle 30 is rotatably mounted with one of the mold parts 3, 4 about its longitudinal axis, but otherwise fixed thereto. The remote from the outer mold 2 further end of the threaded spindle 30 is connected to a drive means 31, such as an electric motor, hydraulic motor, pneumatic motor or the like, in drive connection.

In addition to the further longitudinal guide elements 27 described above, at least one but preferably also a plurality of supporting elements 25 can be provided for stabilizing the entire adjusting device 10. In this embodiment selected here, the or the support elements 25 are seen in the radial direction, arranged on the side facing away from the longitudinal axis 9 of the mold cavity side of the threaded spindle 30. That or the

Supporting elements 25 can in turn be connected to one another on the side remote from the outer mold 2 with the further longitudinal guide elements 27 via the connecting plate 26. Furthermore, the drive means 31 described above can also be attached to this connection plate 26.

To implement the rotary movement into a translational movement, a spindle nut 32 is arranged on the threaded spindle 30. This spindle nut 32 is indicated if with the interposition of the first coupling piece 18 with the mandrel 6 in operative connection or is this coupled with it.

The threaded spindle 30 of the spindle drive is here likewise aligned or arranged radially or laterally with respect to the longitudinal axis 9 of the mold cavity. As a result of this eccentric arrangement, as in all the embodiments described above, the overall length of the adjusting device 10 can be shortened compared to previously known embodiments. The advantage with this embodiment shown here in FIGS. 19 to 22 is that with the maximum adjustment path with the adjoining components, the lingering can be found, since, as a result of the conversion of the rotating movement into a translatory movement, no further moving components are found protrude more beyond the existing components.

In the arrangement of the spindle drive but it would also be possible to arrange the drive means 31 on the mandrel 6 and connected to the threaded spindle 30. The cooperating spindle nut 32 would then be arranged in the region of the connecting plate 26 to 30 with appropriate rotational movement of the threaded spindle adjustment of the mandrel 6 relative to the outer mold 2 to perform. In this case, however, the threaded spindle 30 would then migrate to the side remote from the outer mold 2 side and thus increase the length of the adjusting device 10 during the adjustment of the mold core. However, in order to be able to handle this, the threaded spindle 30 could also be fixedly connected to the outer mold 2 or components of the adjusting device 10 and the spindle nut 32, which is seated on the movable mold core 6, be driven by the drive means 31. Furthermore, it is also possible that one or more threaded spindles 30 are used side by side.

In addition, however, it would also be possible that between the threaded spindle 30 and the drive means 31 also a gear not shown in detail is interposed so as to be able to apply the necessary torques.

In order to be able to reduce further space requirements, it would still be possible to connect the drive gear 11, in particular the threaded spindle 30, with the support element 25 and / or one of the longitudinal guides. to combine elements 23, 27. Thus, for example, the threaded spindle 30 or the threaded spindles 30 could be arranged within the support element or elements 25 and / or the longitudinal guide element or elements 23, 27. Thus, the threaded spindle 30 would at least partially surrounded by the support member 25 and / or the longitudinal guide member 23, 27 and enclosed. This could be favorable in a multiple arrangement of threaded spindles 30.

If the moldings to be produced are formed from a material which shrinks after cooling, these produce an adhesive effect on the mold core 6 during their cooling. In this case, shrinkage can also be used. This results already at the beginning of the adjusting movement of the mold core 6, starting from its working position towards its release position, an increased force requirement, which is better controlled by the previously described arrangement in the cylinder piston formation of the drive member 11 by the available larger piston area. This can possibly be found with smaller cylinder sizes or lower pressures Auslangen and still be carried out the adjustment movement to be performed properly. Since most of the adjusting device 10 is in a vertical or vertical orientation with respect to the outer mold 2, even the weight of the mold core 6 against the force of gravity during the adjustment is to lift with.

Regardless of the previously described parallel alignment of the drive member 11 and the longitudinal guide elements 20, 27 and / or the support elements 25 with respect to the longitudinal axis 9 of the mold cavity, it would still be possible to choose the adjustment while rectilinear, but this at a low angle of inclination with respect to Align longitudinal axis 9 and the mold parting plane 5. Thus, it would then be possible, after opening the outer mold 2, to lift the mold core 6 slightly from the cavity in the direction of the inclined adjustment direction. As a result, a rapid exemption of the molded body is achieved by the outer mold 2 and in the further longitudinal adjustment damage thereof avoided. In addition, however, it would also be possible to design the longitudinal course of the cooperating guide arrangement, in particular the guide track 21 of the longitudinal guide elements 20, 27, differently over its longitudinal extension. Thus, slight different gradients and / or curved guide tracks 21 could be used, so that, for example, at the beginning of the adjustment a stronger slight lifting of the molding Kerns 6 of one of the mold parts 3, 4 takes place and then a frictionless further adjustment can be made to one of the release positions.

In addition, the entire drive and guide arrangement for adjusting the mandrel 6 could be lifted by means of an additional pivoting arrangement of one of the mold parts 3, 4 before the start of the opening movement. Furthermore, however, the entire adjustment could be lifted by means of a spring drive or even a pressure medium drive so as to perform in this case, a friction-free adjustment already from the beginning of the opening movement.

The or the drive members 11 may also comprise a plurality of cylinder-piston assemblies, which can be combined with each other arbitrarily. For example, two or more cylinder-piston assemblies are used side by side and / or one behind the other. Likewise, a short-stroke cylinder could be used for the initial higher demolding force to be applied and then a high-speed cylinder for the remainder of the travel. Likewise, however, a telescopic cylinder could be used as a drive member 11.

Irrespective of this, however, it would also be possible, in addition to the above-described guidance of the mold core 6, to have at least one further guide arrangement, e.g. in the form of slides or the like. Provide, which can support the mold core 6 side.

Furthermore, in the case of the relatively moving components, e.g. the control element 15 and the longitudinal guide member 20, a sensor for detecting the Entformgeschwindigkeit and / or Entformweges provided or integrated therein. It can also be one

Measuring device for determining the expended adjusting force or demolding are provided. This can be done to optimize the demolding and / or demolding force to the limit of the mechanical load capacity of the cooperating components. This can e.g. be performed only once when starting the mold 1 and / or be designed as a constantly active control loop.

FIG. 23 shows a possible further embodiment of a subarea of the molding tool 1, which may be independent of itself, and which in turn is the same Parts same reference numerals or component names as in the preceding Figs. 1 to 22 are used. To avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1 to 22 or referenced.

As previously described with reference to FIGS. 1 to 7 and 8 to 15, the cylinder 12 of the cylinder-piston arrangement for the adjustment of the mold core 6 can be held on at least one of the longitudinal guide elements 20. This shown here further possible way of fastening and mounting the cylinder 12 of the cylinder-piston assembly is carried out such that in the region of the piston rod end of the cylinder 12 with respect to the cylinder axis arranged in a vertical orientation thereto pivot axis 33 is provided, about which the cylinder 12 pivotally is stored. The pivot axis 33 is preferably arranged or formed on both sides and diametrically opposite with respect to the cylinder 12 or the cylinder axis. Thus, for example, the swiveling axes 33 can be formed by bolts or pins 34 arranged on both sides of the cylinder 12, which engage in a recess 35 of a similar configuration. In order to be able to support the pins 34 correspondingly, a rib 36 can be provided on the longitudinal guide element or elements 20 and connected thereto. This rib or ribs 36 are arranged on the side facing away from the mold 1 in particular the outer mold 2 side of the longitudinal guide elements 20 and fixedly connected thereto. This rib 36 can either be an integral part of the longitudinal guide element 20 or else be formed as a separate component and then connected to the longitudinal guide element 20. But it would also be possible to attach the ribs 36 additionally and / or exclusively to the connecting plate 26.

By this pivotal mounting of the cylinder 12 in the region of the pivot axis 33 is here the support and thus power transmission from the cylinder 12 to the outer mold 2 via the rib 36 and subsequently to the or the longitudinal guide elements 20. As already described above, is on the side facing away from the outer mold 2 of the longitudinal guide elements 20 or 20, an additional connection plate 26 is provided, which may be additionally connected to the one or more support elements 25. Furthermore, the rib or the ribs 36 can also be additionally supported on the connecting plate 26 via unspecified connecting elements. This can be a load transfer going from the cylinder 12 into the pins 34 and subsequently on the ribs 36 done. The ribs 36 transmit the force on the one hand to the longitudinal guide elements 20, possibly even on the connecting plate 26, and subsequently also on the support elements 25th

Furthermore, it can be seen from this representation that the cylinder 12 is arranged at its bottom end at a distance from the outer mold 2, in particular the molded part 3, and thus here plant and thus no power transmission takes place. Thus, a support of the cylinder 12 is provided, which takes place exclusively in the region of the piston rod end and the cylinder 12 is supported freely pivotable about the pivot axis 33.

The piston rod end 14 of the piston rod 13 is in turn connected via the previously described, not shown here and designated actuator 15 with the mandrel 6, if appropriate, with the interposition of the coupling pieces 18 and / or 19. The adjusting element 15 can in turn be guided guided in the longitudinal guide element 20, whereby a sufficiently long guide length and thus a pinch-free adjustment can be achieved. The mandrel 6 is in turn also guided guided on the longitudinal guide elements 20.

By this oscillating, free mounting of the cylinder 12, this can move freely in its bottom end, whereby in this area no directly acting moments on the longitudinal guide elements 20 and the support elements 25 are introduced. The longitudinal guide selemente 20, optionally in conjunction with the support members 25 and the connecting plate 26, form a support device for the drive member 11, which is here formed by a cylinder 12 from. This support device is thus part of the mold 1 and usually attached to one of the mold parts 3, 4 of the outer mold 2.

In all the embodiments of the molding tool 1 described above, the mold core 6 to be adjusted defines a cross section in a plane aligned perpendicular to the longitudinal axis 9. The drive member 11 is then always arranged so that it does not protrude into the required cross-section of the mandrel 6 and is thus arranged laterally next to the mandrel 6. For the sake of order, it should finally be pointed out that, for a better understanding of the construction of the molding tool 1, in particular its adjusting device 10, these or their components have been shown partially unevenly and / or enlarged and / or reduced in size.

The task underlying the independent inventive solutions can be taken from the description.
