Mold apparatus for an injection molding machine and method of making an article of elastomeric material

The invention relates to a molding apparatus for an injection molding machine and a method for producing an article of an elastomeric material in such a molding apparatus as described in claims 1 and 21.

From EP 1 212 183 Al a device for the injection molding of an article of an elastomeric material is known. The device is surrounded by two opposing outer mold parts which are opposite one another and which can be adjusted relative to one another and which in an abutting state define a cavity for receiving in the plastic state and under pressure, elastomeric material. Hin to the adjustment of at least one of the outer moldings vertical adjustment are further Versteilantriebe engageable on opposite faces of the mold parts during the closing process of the device jaws, which are optionally provided with protruding into the cavity mold cores and further with locking elements, the moldings against each other against the applied internal pressure during insertion lock the elastomeric material.

EP 1 932 974 B1 has disclosed a plastic infiltration module for creating a subterranean infiltration system. This infiltration module comprises a main body of six mutually perpendicular, outer-level outer walls, which have at least partially water-permeable grid structures and an inner chamber. The main body forming the infiltration module is designed as a cube, with continuous insertion openings being provided in all six outer walls in each case relative to the inner chamber. The inner chamber is free of struts or

Support columns formed. The insertion openings have an opening size that is between 30% and 60% of the outer wall surface. Furthermore, insert plates having an insertion opening size are provided which, at least in regions, have a water-permeable grid structure and serve for selective insertion into selected insertion openings.

Another plastic infiltration block has become known from EP 1 607 535 B1. This also serves to form an underground structure for infiltration or damping purposes. This infiltration block has a substantially rectangular, cuboid shaped body with pairs of opposing first, second and third surfaces. Such a block is formed from two mutually identically designed component halves, which are assembled in a longitudinal separation plane. The two components have adjacent half-shell-shaped depressions, between which a web is formed. This web has transversely to its longitudinal extent additionally also a half-shell-shaped recess on. By assembling the two components of the rectangular block is created, which is then interspersed by two juxtaposed through holes, which can serve as an inspection channel. In the middle region of the web, a passage formed transversely to the passage openings is formed. In addition, closable openings can still be arranged in the continuous side walls, which allow access to the common passage opening of the two half-shell-shaped components. The outer walls are formed by a permeable grid structure.

The object of the invention is to provide a molding apparatus for producing an article of thermoplastic material in an injection molding, which ensures a short cycle time and automated operation by small displacement of the moldings with both in the axial and radial direction in the cavity projecting core parts.

This object of the invention is achieved by the reproduced in the characterizing part of claim 1 features. The advantage in the embodiment of the molding device with an outer mold arranged on an adjustable mold-carrying device is a high design possibility of a mold cavity and of core moldings that can be achieved with it.

Are possible further advantageous embodiments, as described in claims 2 and 3, because a very compact and small in their outer dimensions held outer shape is achieved, whereby their arrangement is simplified to an adjustable support device. However, further advantageous are also embodiments as described in claims 4 to 6, because this compact functional units for their combination on the support device to form an entire outer shape can be achieved. But there are also the embodiments according to claims 7 and 8 advantageous, whereby a very variable process flow in the manufacture of the article is achieved in the molding apparatus.

In accordance with the advantageous embodiment described in claim 9, a stable uptake is achieved for the mold modules with the mold segments.

In the embodiment according to claim 16 is advantageous because it can be dispensed with additional high closing and holding forces of the drive units for the molding device parts. Furthermore, so can be found with a lower energy consumption Auslangen, which is achievable, especially in large mold parts a high savings potential.

Finally, however, the embodiments according to claims 17 to 20 are advantageous because high closing forces for the actuators are avoided by the internal force adhesion between the individual moldings. However, the invention also relates to a method for operating an injection molding machine with the molding apparatus according to the invention, as described in the preamble of claim 21.

This object is achieved by the reproduced in the characterizing part of claim 21 measures, the advantage is that even small process and opening paths are sufficient for an entire molding cycle, thus reducing the cycle time and automated operation is achieved.

By way of introduction, it should be noted that in the variously described embodiments, identical parts are provided with the same reference numerals or the same component designations, wherein the disclosures contained in the entire description can be applied mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and are to be transferred to the new situation mutatis mutandis when a change in position. Furthermore, individual features or combinations of features from the different exemplary embodiments shown and described can also represent independent, inventive or inventive solutions.

All statements on ranges of values in objective description are to be understood as including any and all sub-ranges thereof, eg the indication 1 to 10 should be understood to include all sub-ranges, starting from the lower limit 1 and the upper limit 10 ie all subregions begin with a lower limit of 1 or greater and end at an upper limit of 10 or less, eg 1 to 1.7, or 3.2 to 8.1 or 5.5 to 10. In Figs. 1 to 3, a first infiltration module 1 is shown, which encloses a main body 2 with six outer walls 3 to 8 which are arranged in pairs and have outer planar outer surfaces. Here, the outer walls 3 and 4 form a first pair of outer walls and are arranged at the selected representation in Fig. 1 above and below. The second pair of outer walls 5 and 6 form a front or rear side of the main body 2. Finally, the third pair of outer walls 7 and 8 limits third outer walls, which thus bound the base body 2 laterally. The main body 2 of the infiltration module 1 is preferably formed from a plastic material, wherein this can be produced in an injection molding process. Furthermore, it is shown here that at least some of the outer walls 3 to 8 in part have a liquid-permeable lattice structure 9 or are formed by them. As can be seen further from the illustration of FIG. 1, the base body 2 in the region of its outer sides a substantially cube-shaped - ie cube-shaped - spatial form, in the ten ten Seitenenkan 10 of the individual outer walls 3 to 8 are formed equal to each other , Thus, here limit the two side edges 10, the first pair of the first outer walls 3 and 4 in the corner towards the third pair of third outer walls 7 and 8. The other side edges 11 also limit the first pair of outer walls 3 and 4, but in the corner Finally, the third side edges 12 define the second pair of second outer walls 5 and 6, respectively, toward the third pair of third outer walls 7 and 8, respectively. By virtue of the paired outer walls 3, 4; 5, 6; 7, 8 each aligned parallel to each other and the individual pairs are additionally aligned with each other in the vertical direction and have the same length side edges 10 to 12, the base body 2 is formed in the form of a cube.

The main body 2 comprises here in the region of the pairwise opposite outer walls 3 and 4 each have a top flange 13 and a bottom flange 14 and a top and bottom flange 13, 14 interconnecting web 15. Here, the web 15 is continuous between the upper and lower flange 13, 14 formed. Furthermore, the web 15 in the vertical direction with respect to the upper and lower chord 13, 14 bounding outer walls 3, 4 and continuously between the upper and lower chord 13, 14 frontally bounding second outer walls 5, 6 aligned. A plane of symmetry 16 is on the one hand in the vertical direction with respect to the first outer walls 3, 4 and on the other hand centrally between the third outer walls 7 and 8, which are arranged laterally with respect to the web 15, aligned. The web 15 is arranged centrally in its cross section with respect to the plane of symmetry 16 extending. As can now be seen from a synopsis of FIGS. 1 and 2, the main body 2 of the infiltration module 1 in a view of the second outer wall 5 has an approximately "I" -shaped cross-section in a vertical plane on the plane of symmetry 16 Both third side walls 7 and 8 are here only partially formed and form narrow Stirn- surfaces 17 to 20 out. The web 15 is defined in its cross section on both sides by a C-shaped boundary 21, 22. In this case, the two boundaries 21, 22 on the side facing away from each other to the web 15 laterally adjacent third outer walls 7, 8 are open. Ends 23, 24 of the boundaries 21, 22 affect the upper and lower chords 13, 14 on the mutually facing sides of the straps. Thus, the two boundaries 21, 22 each form a half-shell-shaped recess 25, 26 in the third outer walls 7, 8.

The boundary 21, 22 defining the web 15 laterally can be formed by a boundary wall 27, 28. In addition, in the boundary wall 27, 28 also these passing through recesses 29 may be arranged or provided. On the one hand to give the boundary wall 27, 28 and thus the web 15 sufficient strength and on the other hand to create the possibility that liquid can flow through the recesses 29, here are the recesses 29 in a top and bottom chord 13, 14 closer Arranged area. So that the individual recesses 29 can communicate with the lattice structure 9, at least some of the recesses 29 are in fluid communication with the lattice structure 9.

As can now be seen better from a synopsis of FIGS. 1 and 3, in the web 15 a in the vertical direction with respect to the longitudinal extent of the web 15 aligned breakthrough 30 is arranged, which passes through the web 15 entirely. Furthermore, here the breakthrough 30 has a longitudinal extent, which with respect to the upper and lower chord 13, 14 bounding the first outer walls 3, 4 is aligned parallel to these. Thus, the longitudinal extent or a longitudinal axis of the opening 30 in the vertical direction is aligned with the plane of symmetry 16. Further, the aperture 30 may have a cross-sectional area having a size in a range with a lower limit of 20% and an upper limit of 50% with respect to a complete area of an outer wall 3 to 8 of the main body 2. As a result, a transverse connection between the two half-shell-shaped recesses 25, 26 arranged in the third outer walls 7, 8 is created within the web 15. If this breakthrough 30 is provided, the web 15 is reduced in each case in the region of the second outer walls 5, 6 to a columnar design. Furthermore, the opening 30 can also be circumferentially provided with a lining 31. In addition, it is also possible that these openings 32 passing through are still arranged in the lining 31 of the opening 30. FIGS. 4 to 6 show a further embodiment of a further infiltration module 33, 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 3. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1 to 3 or reference.

The further infiltration module 33 shown here, in its spatial form, is designed as one half of the main body 2 of the first insurance module 1 with respect to its plane of symmetry 16. The main body 34 of the further insurance module 33 is also here by analogous to the previously described outer walls 3 to 8 here also in pairs, parallel to each other and at a distance from each other arranged first, second and third outer walls 35, 36; 37, 38; 39, 40 formed. The arrangement according to the representation in FIG. 6 has been selected analogously, as has already been done in the case of the first infiltration module 1.

The symmetry plane 16 described above is arranged here in FIG. 6 in the region of the third outer wall 39. In the area of the two first outer walls 35, 36, the main body 34 in turn has a top flange 41 and in the region of the other, first outer wall 36 the bottom flange 42. Between the upper flange 41 and the lower flange 42 extends in the region of the third outer wall 39, a web 43. In the region of the third outer wall 40 is a web 43 defining the C-shaped, further boundary 44 is provided, the further half-shell-shaped recess 45 in the third outer wall 40 forms here. The further boundary 44 or the depression 45 formed thereby can likewise be formed by a further boundary wall 46. In this exemplary embodiment shown here, the boundary wall 46 is continuous and thus formed without any recesses or openings. The outer walls 35 to 40 described above may in turn comprise, in regions or sections, the lattice structure 9 described above or be formed by them. On the third outer wall 40 of the main body 34, analogous to the two end faces 19 and 20 of the first basic body 2, further end faces 47, 48 are formed here. The two end faces 47, 48 thus form the remaining, third outer wall 40.

FIG. 7 shows a partial section of a infiltration system 49, which is formed here by a first infiltration module 1 and a further infiltration module 33. Here, the further infiltration module 33 is attached to the first infiltration module 1 in such a way that the two half-shell-shaped recesses 25, 45 of the first and further infiltration modules 1, 33 form a common passage opening 50. To achieve this position, the two end faces 47, 48 of the further infiltration module 33 are arranged adjacent to the end faces 17, 18 of the first infiltration module 1. This forms a separation plane between the two infiltration modules 1, 33.

In addition, however, it would also be possible, in the region of the third outer wall 8 of the first infiltration module 1 with its end faces 19, 20, to arrange another infiltration module 33 or else a similarly designed first infiltration module 1 adjacent thereto.

Furthermore, it is also possible for at least one infiltration modules 1, 33, which together define or form at least one passage opening 50, at least one plate-shaped cover element 51 covering the passage opening 50 on at least one outer wall 3 to 8 or 35 to 40 adjacent thereto. The cover 51 spans the dividing plane between adjacent infiltration modules 1, 33 and can additionally serve for the mutual retention of the two infiltration modules 1, 33. The cover element 51 shown here in simplified form will be described in detail in the following figures. For holding the cover 51 to the infiltration modules 1, 33 may, for example, to the

Leakage modules 1, 33 latching recesses 52 and the cover 51 of this superior locking projections 53 may be provided. In accordance with mutual arrangement and recess of the recesses 52 on the basic bodies 2, 34 of the two Versicke- The modules 1, 33 can thus be modularly assembled to the infiltration system 49.

Furthermore, it is shown in simplified form here that the infiltration modules 1, 33 which are arranged directly adjacent to each other, these mutually aligning positioning elements

54 can be arranged or provided. These are in intended for this purpose Positionieraufnahmen 55 of the two infiltration modules 1, 33 optional. This results in a mutual alignment and positioning of the individual infiltration modules 1, 33 to form the infiltration system 49. Thus, a modular arrangement and any combination in the most diverse manner possible. In the positioning shots

55 but also extensions of the cover 51 may be used so as to achieve a mutual centering between these components. The extensions of the cover 51 will be described later in detail. FIG. 8 shows a simplified arrangement possibility of different infiltration modules 1, 33 to another infiltration system 49. In this case, the first row of the infiltration system 49 shown here above, starting from left to right, is formed by a further infiltration module 33, two first infiltration modules 1 and, at the end, another infiltration module 33. Subsequently, a first infiltration module 1 and subsequently another infiltration module 33 are provided in the further row below. The here formed in the first row, common through holes 50 are aligned here in the illustration in the vertical direction. In the third row from above, a single, further infiltration module 33 is provided, wherein here the orientation of the common passage opening 50 in the vertical direction with respect to the passage openings 50 in the first row. Also in this area can be arranged on the outer walls 3 to 8 or 35 to 40 correspondingly formed cover 51.

FIGS. 9 and 10 show a possible embodiment of the cover element 51, which is possibly independent of itself, again using the same reference numerals or component designations for the same parts as in the preceding FIGS. 1 to 8 become. To avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1 to 8 or reference.

This cover element 51 formed from a grid structure 56 is adapted in its outline shape to the length of the side edges 10 to 12 of the main body 2 and here has the same

Side length up. Thus, the cover 51 is seen in plan view square. The self-contained grid structure 56 forms a rust-shaped component, which can serve to cover the passage opening 50 described above. The otherwise plate-shaped lattice structure 56 has throughout the same height or strength, which is adapted to the loads to be removed therewith. For positioning the cover 51 on the infiltration module 1 or 33, this positioning lugs 57, which project beyond the grid structure 9 in the direction perpendicular to their strength. These positioning lugs 57 can be used in the previously described positioning receptacles 55. As a result, a rotation of the cover element 51 relative to the infiltration modules 1, 33 is prevented. At the same time, however, a relatively good mutual support of directly abutting infiltration modules 1, 33 is achieved by the overstretching of both modules 1, 33. In order to prevent inadvertent lifting or detachment of the cover element 51 from the infiltration modules 1, 33, here again the detent projection 53 is shown in closer detail, which likewise projects beyond the lattice structure 56 in the vertical direction. Again, several of these locking projections 53 are again provided and engage in the infiltration module 1, 33 attached position in the arranged there or provided recesses 52, as has already been described previously in FIG. 8. The lattice structure 56 associated with the passage opening 50 is here arranged eccentrically with respect to the center of the passage opening 50 in its internal construction. This results in an area to an increased arrangement of webs, wherein in the opposite region, the opening widths between the webs are chosen to be larger. FIGS. 11 and 12 show a further embodiment of the cover element 51, which is possibly independent of itself, again using the same reference numerals or component designations for the same parts as in the preceding FIGS. 1 to 10 become. To avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1 to 10 or reference.

This cover element 51 shown here is again formed by a grid structure 56 that is transparent to the versor modules 1, 33. Likewise, the locking projections 53 and positioning lugs 57 described above are also provided. In contrast to the cover element 51 described above, this cover element 51 shown here has a central passage 58 which is freely formed by any grid structure and leads into the passage opening 50. Depending on the choice of the size of the passage 58, this can also serve as an inspection opening, for example.

As can now be better seen in FIG. 12, an annular shoulder 59 defining the passage 58 projects beyond the grid structure 56 to the side which is remote from the positioning lugs 57. Thus, this approach 59 projects beyond the covering element 51 to the side facing away from the infiltration modules 1, 33.

As seen in plan view, this covering element 51 can once again have the same side edge length as previously described for the length of the side edges 10 to 12 of the infiltration module 1.

FIG. 13 shows a further embodiment of the infiltration module 1 consisting of the base body 2 with the liquid-permeable lattice structure 9.

The latter has parallel alignment in relation to the symmetry plane 16 defined relative to the outer walls 7, 8, the upper flange 13, web 15 and lower flange 14 extending over a module height 60 and two wall disks 62, 63 running at a small distance 61 from one another.

The wall disks 62, 63 extend symmetrically to the plane of symmetry 16 and extend over an entire module width 64.

The wall disks 62, 63 are interrupted in the region of the approximately circular opening 30 which crosses the web 15. In the region of the opening 30, the wall openings Discs 62, 63 also interrupted and thus extend from the opposite side surfaces 5, 6 of the infiltration module 1 and are connected to the breakthrough 30 comprehensive panel 31. Corresponding to the grid structure 9, the parallel wall plates 62, 63 are connected to the distance 61 bridging intermediate webs 65, whereby a high stability of the infiltration module 1 is ensured in its application as a one-piece unit.

By means of this design with the wall disks 62, 63, it is possible to divide the infiltration module 1 along the plane of symmetry 16 into two half elements 66, 67 by means of a separating process of the intermediate webs 65, for example by means of a saw cut.

It is advantageous, furthermore, if according to the lattice structure 9, at least in some areas, the wall disks 62, 63 have openings 68, as for example also provided on the side surfaces 17, 18 of the infiltration module 1 and shown in FIG.

FIGS. 14 to 16 show a closure part 70 for closing the opening 30, as can be seen, for example, from FIG. 13. This closure part 70 has an arcuately curved base plate 71 about an axis with which the opening 30 is covered and is provided with an integrally formed centering ring 72 which can be inserted into the aperture 30 and thus the closure part 70 is held.

In addition, further stiffening rings 74 are formed integrally within the centering ring 72 and to this and to a central axis 73 concentrically on the base plate 71 and give the closure part 70 a corresponding stability and load capacity.

As can be seen further from the FIGURE, openings 75 are provided, for example, in the base plate 71, as a result of which fluids collecting in the base plate 71 of the closure part 70 can flow away. FIGS. 17 and 18 show a plug connector 76 for a position-exact juxtaposition or joining together of infiltration modules 1, for the production of a multiple infiltration system 1 comprising infiltration modules 1. This connector 76 is preferably a plastic injection molded part, with symmetrically arranged with respect to a center plane 77, an approximately square cross-section, having inserts 78. These are preferably hollow parts and have tapered insertion ends 79. The cross-sectional dimension of the inserts 78 corresponds approximately to the cross-sectional dimensions of the lattice structure of the infiltration module.

As can further be seen from the figures in broken lines, it is possible, for example, to connect two such inserts 78 to form a one-piece component by means of a band 8, in order to thus also establish cross-module cohesion of adjacent infiltration modules. Furthermore, it is of course possible to provide the band 80 with only one side of this superior insert 78.

The object of the invention for the above-described infiltration modules or the infiltration system formed therefrom can be seen therein to provide a percolation module and a seepage system composed thereof, which has a high intrinsic stability with low material expenditure and offers a high possibility of variation during assembly. In addition, the volume to be transported should be kept low.

FIG. 19 shows a production device 101, in particular injection molding machine 102, with a shaping device 103 in a greatly simplified representation.

The molding device 103 is attached to a first base mold part 104 directly on a machine main 105, a discharge nozzle 106 of an extruder cylinder 107 attached. A second base mold part 108 is arranged on a slide 109 of the injection molding machine 102 which is opposite the machine main 105 and which is adjustable in a machine longitudinal direction. For this purpose, guideways 111 running parallel to an extruder longitudinal axis 110 are provided on a machine bed 112 of the injection molding machine 102. The adjustment of the carriage 109 is effected by means of a drive arrangement 113, for example by at least one hydraulic cylinder 114, which acts in its hydraulic direction of action parallel to the extruder longitudinal axis 110 on the one hand on the carriage 109 and on the other hand on the machine main 105. Thus, the carriage 109 relative to the machine main 105 - according to double arrow 115 - and thus the base moldings 104, 108 of the molding apparatus 103rd

Between facing end surfaces 116, 117 of the base moldings 104, 108 is an outer mold 118, which according to the embodiment shown by at least two, with respect to the extruder longitudinal axis 110 radially opposite mold segments 119, 120 formed, which is parallel to a footprint 121 extending Forming graduation level 122.

The outer mold 118 with the mold segments 119, 120 is arranged on a support device 123. This is in a guide assembly 124 in a direction parallel to the extruder longitudinal axis 110 direction - according to double arrow 125 - by means of a drive assembly 126, for example a hydraulic cylinder 127 adjustable and thus relatively at least to one of the base moldings 104, 108 adjustable. According to the exemplary embodiment shown, the guide arrangement for the carrying device 128 is formed by at least one guide rod 128 having a central axis 129 extending parallel to the extruder longitudinal axis 110, wherein the guide rod 128 is anchored in the machine main 105 and extends in the direction of the carriage 109 over a length 130. As can now be seen further from FIG. 19, for example, core mold parts 131, 132 projecting into the outer mold 118 are arranged on the base moldings 104, 108, which with an outer contour 133 and an inner contour 134 of the mold segments 119, 120 provide a cavity 135 corresponding to one Form an article to be produced 136, wherein the elastomeric material is supplied via feed channels in the base molding 104.

In the embodiment shown, the outer mold 118 is formed by two of the mold segments 119, 120, the number of mold segments required for the outer mold 118 depending on the complexity of the shape of an article to be manufactured and Therefore, an additional number of mold segments and thus a division of the outer shape in multiple levels 137 is possible.

The mold segments 119, 120 form wall moldings 138 as elements of attached to the support device 123 form modules 139 further have a guide assembly 140 and an actuator 141 for the mold segments 119, 120 and thus form a unitary assembly whose mounting on the support device 123 accordingly the required number is simply possible - as will be described in detail below. 20, 21 show now the forming device 103 for forming the cavity 135 between the core moldings 131, 132 having base moldings 104, 108 and the outer mold 118 forming, according to these embodiments four arranged on the support mold modules 139, with the in the extruder longitudinal axis 110 in the radial direction adjustable mold segments 120, 119th

In such an arrangement with four form modules 139, two mutually perpendicularly oriented and the extruder longitudinal axis 110 receiving division planes 142, 143 are formed by the configuration of the mold segments 120. The support device 123 form two parallel aligned and distanced from each other at a distance 144 support rings 145, 146, which are mounted on two diametrically opposite the Extrudermittelachse 110 diametrically opposite guide rods 128 - according to the double arrow 125 - and to the support device 123 is equipped with plain bearing bushes 147 ,

Between the support rings 145, 146, the mold modules 139, each consisting of the mold segment 120, guide assembly 140 and actuator 141 are arranged. In the exemplary embodiment shown, the actuator 141 forms a double-acting cylinder 148 which can be acted upon by a pressure medium and which is fastened to the support rings 145, 146 with a cylinder housing 149 between mounting surfaces 150, 151 located opposite one another.

The guide arrangement 140 of the molding segment 120 is formed by four anchored in this guide columns 152, the cylinder housing 149 in bearing bores 152 durchra- gene and additionally positioned over a yoke plate 153 in a projecting end portion 154. The arrangement of the cylinder housing 149 is positioned in a clearance between the associated with a piston rod 155 of the cylinder 148 and according to double arrow 156 adjustable mold segment 120 and the yoke plate 153.

It can also be seen from FIG. 21 that in a closed position of the shaping device 103, the molding segments 120 are positioned relative to one another in a positive and non-positive manner relative to each other by means of the base moldings 104, 108. In this case, the mold segments 120 form in their closed position a centering surface 157 with a truncated cone outer lateral surface 158, with which the mold segments 120 protrude into one of the base moldings 104, 108, wherein the centering receiver 159 has a truncated cone inner lateral surface 160. Thus, a secure locking in the closed position of the mold segments 120 is achieved with respect to the occurring during injection of the molding material in the cavity 135 high internal pressure and thus kept the required closing forces low.

Further centering of the mold segments 120 in their relative closed position relative to one another is achieved, for example, in the closed position of the mold segments 120 by interlocking positioning means 161, for example positioning wedges, in facing end faces or on the outer circumference of the mold segments 120.

By means of the previously described conception of the shaping device 103 with the relatively adjustable base moldings 104, 108 and the independently adjustable support device 123 with the forming modules 139 and with the independently adjustable mold segments 119, 120, very complex cavities can be formed in their outer contours and inner contours 135 can be achieved in that core moldings 131, 132 extend in the direction of the extruder longitudinal axis 110 and in cross-planes on the mold segments 119, 120 core extensions 162, 163 are possible and thus complex objects can be realized particularly economically and with high dimensional accuracy in an injection process , FIGS. 22 to 24 show in simplified form the forming device 103 with four mold segments for explaining the method steps for producing the article 136 by injection molding. In the closed position shown in Fig. 22 of the mold segments 119, 120 and - according to arrow 164 - in the direction of provided with injection channels 165 base molding 104 to the mold segments 119, 120 employed basic mold part 108 is the closed cavity 135 for injecting the thermoplastic material over the Extruder cylinder 107 reaches and the injection process is started via the machine control, not shown, and thus the article 136 is formed in the cavity 135.

FIG. 23 shows the further method step in which the base shaped part 108 with the core shaped part 132 is displaced, as shown by arrow 166, into a corresponding distance from the mold segments 119, 120, the core shaped part 132 being completely out of the mold segments 119, 120 in its is held in the same closed position.

In FIG. 24, the carrying device 123 with the mold segments 119, 120 comprising the article 136 in its closed position is adjusted as shown in arrow 167, the article strands being separated from the material strands of the injection channel 165 and also a removal of the article 136 from the arranged on the base molding 104 core molding 131 takes place.

FIG. 25 shows a concluding method step, in which the object 136 is grasped by a gripping device 168 of a handling device 169 and after which the shaped segments 119, 120 are adjusted to the open position according to arrows 170 and the object 136 is displaced by the handling device 169 the area of the injection molding machine is removed and after a closing operation of the molding apparatus 103, the manufacturing cycle is completed. As a variant of the embodiment shown is also a detection of the article 136 with the gripping device 168 on outer surfaces in the molding apparatus 103 with the four mold segments 119, 120 by the independent adjustment of this then possible if, for example, two opposite arranged over mold segments 119, 120 in the open position - are provided, and so that a free space for detecting the object is provided by the gripping device, while the other two mold segments still hold the object.
