Description

Technical Field

[0001] The present invention relates to a component and a method for operating a component having a first mold clamping unit and at least one second mold clamping unit for a molding machine. Background Technology

[0002] In practice, there has been a greater expectation for larger clamping units for molding machines, for example, in order to manufacture larger injection molded parts.

[0003] At the same time, modern modular units have reached a reasonable manufacturing limit in terms of size, as they become completely unusable for efficient transport when further increased in size. Related limitations include, for example, the maximum transport weight, the size of standard containers, and the availability of space for transport by rail or by truck, i.e., the availability of space for transportation infrastructure in principle. Summary of the Invention

[0004] Since transportation infrastructure cannot be easily improved in this regard, the expectation for larger mold-forming units can only be met with significantly increased technological expenditures, for example by designing the mold-forming units in a way that allows them to be shipped as parts or structural assemblies.

[0005] Therefore, the objective of this invention is to provide a larger mold clamping unit for a molding machine without incurring excessive technical costs.

[0006] The task regarding the mold clamping unit is solved by a component for a molding machine having a first mold clamping unit, the component comprising: - Suitable for supporting a first fixed forming platen for at least one forming mold and a first movable forming platen movable relative to this. - At least one first clamping force mechanism, the first clamping force mechanism being configured to apply a clamping force to a first movable forming platen. - A control or adjustment unit configured to control or adjust the first clamping force mechanism. Wherein, at least one second mold-closing unit is provided next to the first mold-closing unit, the second mold-closing unit including - Suitable for supporting a second fixed forming platen or a first fixed forming platen and a second movable forming platen relative to it, which can move relative to this, for supporting at least one forming mold. - At least one second clamping force mechanism, the second clamping force mechanism being configured to apply a clamping force to a second movable forming platen. The control or regulation unit is configured to, - Control or adjust the at least one second clamping force mechanism, and - When the first fixed forming platen, the first movable forming platen, and, if necessary, the second fixed forming platen and the second movable forming platen jointly support at least one forming mold, the at least one first clamping force mechanism and the at least one second clamping force mechanism are manipulated for synchronous clamping force loading.

[0007] The present invention also claims a method for operating an assembly for a molding machine having a first mold clamping unit and at least one second mold clamping unit, wherein...

[0008] - The at least one second mold-closing unit is positioned next to the first mold-closing unit, and

[0009] -At least one first movable forming platen of the first mold clamping unit is loaded with a first portion of the mold clamping force by the first mold clamping force mechanism, and

[0010] - At least one second movable forming platen of the at least one second clamping unit is loaded with at least one second partial clamping force by at least one second clamping force, and

[0011] -Simultaneously apply the first part of the mold clamping force and the at least one second part of the mold clamping force.

[0012] Furthermore, this invention claims protection for a molding machine having components according to the invention.

[0013] Molding machines can be understood as injection molding machines, die casting machines, presses, and similar devices.

[0014] Initially, the idea that two side-by-side mold clamping units could jointly support at least one mold and operate synchronously seemed somewhat far-fetched. However, the applicant's research surprisingly concluded that it could fully meet the steady-state requirements of the mold clamping units and the requirements for the precision of synchronous control or adjustment.

[0015] Of course, larger mold-closing units can also be achieved by setting up additional mold-closing units (third, fourth, etc.) next to the first and second mold-closing units.

[0016] In a preferred embodiment, the first mold-closing unit and the at least one second mold-closing unit each include a fixed forming plate, wherein the first fixed forming plate and the at least one second forming plate are implemented separately from each other.

[0017] The feasibility of arranging multiple mold clamping units side by side and / or stacked, especially with mold clamping axes oriented parallel to each other, includes the advantage of achieving arbitrarily large mold clamping sides or forming pressure surfaces in a flexible manner without changing the size of individual components.

[0018] The advantage here is that it can be processed, manufactured, and transported using equipment that meets the standards.

[0019] The feasibility of arranging multiple mold-forming units side by side includes another advantage: by varying the positioning of the movable forming platen, the at least one forming mold is not necessarily required to be a right parallelepiped shape, thereby enabling optimization of the geometry and / or quality of the at least one forming mold.

[0020] The first mold closing unit and the at least one second mold closing unit, or the first fixed molding plate, the first movable molding plate, the second fixed molding plate, and, if necessary, the second movable molding plate, are configured to jointly support at least one molding die.

[0021] Alternatively, the first mold closing unit and the at least one second mold closing unit may include a single fixed molding platen, such that the first fixed molding platen, the first movable molding platen, and, if necessary, the second movable molding platen together support at least one molding die.

[0022] Common support should be understood as at least one molding die being supported by at least two mold-closing units.

[0023] In other words, at least one molding die reaches at least two mold areas of at least two mold closing units at least partially.

[0024] Another advantage is that optimized clamping force distribution can be achieved through the changing positioning of the movable forming platen and / or tie rods and push rods and / or drive mechanism. For example, this can enable weight savings in the forming platen.

[0025] The advantages of smaller mold clamping units are, for example: - The manufacturing of some of its components requires less manufacturing technology costs, and / or - Assembly and disassembly are simpler to implement based on smaller components, and / or -Transportation and / or manufacturing are more advantageous from an ecological and / or economic perspective.

[0026] It can be used not only in horizontal forming machines but also in vertical forming machines to realize the components according to the invention. That is, the mold clamping units arranged side by side include mold clamping axes that are parallel to each other, and the mold clamping axes can be oriented vertically or horizontally.

[0027] The mold closing axis is understood as a basically linear direction of motion, and the movable forming platen can move along the direction of motion.

[0028] For implementing the components according to the invention, not only existing mold-closing units can be used, but additional mold-closing units can also be used, thereby enabling, for example, the implementation of the components according to the invention during the process of supplementing equipment.

[0029] In principle, many prior art mold-closing units include separate drive mechanisms for rapid stroke and power stroke. This can also be configured in the case of a first mold-closing unit and / or a second mold-closing unit in this invention.

[0030] The drive unit can be understood, for example, as a hydraulic cylinder and / or a spindle drive unit.

[0031] For example, rapid strokes can be achieved using electric, hydraulic, or magnetic drive devices for faster movement of movable forming plates, so that mold closing or opening movements can be performed.

[0032] The term "dynamic stroke" refers to the application of clamping force in the sense of force exertion and is not necessarily understood literally as motion.

[0033] Different drive units used for rapid stroke and power stroke can also be called rapid stroke drive units or power stroke drive units.

[0034] A power stroke drive device, such as the four hydraulic cushions of a double-plate mold clamping unit, can be called a mold clamping force mechanism.

[0035] There is currently a first mold clamping force mechanism for the first mold clamping unit and a second mold clamping force mechanism for the second mold clamping unit.

[0036] The simultaneous application of clamping force to the first and second movable forming plates can be understood as the existence of at least one moment in which not only the first movable forming plate but also the second movable forming plate are each loaded with a partial clamping force. In other words, the time interval between the partial clamping force loading of the first and second clamping units includes at least a certain overlap.

[0037] In a particularly preferred embodiment, the partial clamping force loading of the first and second movable forming plates can be completely synchronized. That is, the interval between the partial clamping force loading can be the same not only with respect to its length but also with respect to its start and end times.

[0038] The sum of the partial clamping forces produces the total clamping force.

[0039] It should be mentioned that the first mold-closing unit and the second mold-closing unit can be the same type or different types of mold-closing units.

[0040] In a preferred embodiment, the movements of the first and second movable forming plates can be performed simultaneously. It is understood that there exists at least one moment in which not only the first movable forming plate but also the second movable forming plate moves. In other words, the time interval between the movements of the movable forming plates of the first and second mold closing units includes at least a certain degree of overlap.

[0041] In a particularly preferred embodiment, especially when the first fixed forming platen, the first movable forming platen, the second fixed forming platen, and the second movable forming platen jointly support at least one forming mold, the movements of the first and second movable forming platens can be completely synchronized. That is, the starting and ending positions, starting and ending times, and / or speeds of the movable forming platens can be the same.

[0042] The mold-closing units can be configured to move sequentially, wherein separate mold-closing force mechanisms and / or drive devices can be provided for two or more mold-closing units.

[0043] The first mold-closing unit and the at least one second mold-closing unit may each include at least one hydraulic and / or electric drive device.

[0044] Hydraulic drive devices are understood, for example, as hydraulic cylinders, hydraulic cushions, or pressure pads, wherein the hydraulic cylinders, hydraulic cushions, or pressure pads are preferably used for the power stroke.

[0045] An electric drive device is understood, for example, as an electric motor, whose driving motion can be converted into linear motion through a ball screw or spindle drive device. The electric drive device is preferably used for rapid stroke motion.

[0046] The clamping force loading of the first and at least one second clamping unit can be based on different clamping force mechanisms, so the first and second clamping units can have different components.

[0047] As a particularly preferred implementation variation, the first and second mold-closing units each include at least one fixed forming plate and a movable forming plate; that is, they are double-plate mold-closing units.

[0048] Alternatively, the first mold-closing unit and the at least one second mold-closing unit may also include more, preferably three, plates, for example, through an additional arrangement of one end plate each.

[0049] When using a hydraulic drive, it is preferable to configure a first clamping force mechanism to be connected to a first hydraulic pipeline system and the at least one second clamping force mechanism to be connected to at least one second hydraulic pipeline system.

[0050] A hydraulic piping system is a system of hydraulic lines that supply hydraulic oil to one or more hydraulic cylinders, and through which a pump system drives one or more consumers, such as hydraulic cylinders, by applying pressure.

[0051] Hydraulic piping systems may include different types of valves and / or be connected to different types of valves.

[0052] The detailed implementation of valves in a hydraulic piping system, such as their type and / or components, typically depends on whether they involve rapid stroke or powered stroke.

[0053] Here, the component used to operate the first mold-closing unit and / or at least one second mold-closing unit is preferably a valve, especially at least one proportional valve, such as a 4 / 3 directional proportional valve, through which the direction and / or speed of the at least one hydraulic cylinder can be controlled or adjusted.

[0054] The direction and / or speed of the at least one hydraulic cylinder can be controlled or regulated here, in particular by means of different types of valves, by releasing and / or locking selected lines of the first hydraulic line system and / or the at least one second hydraulic line system, wherein the fluid flow within the first hydraulic line system and / or the at least one second hydraulic line system is controlled or regulated.

[0055] In a double-plate mold closing unit, each mold closing unit preferably uses two hydraulic cylinders, which are preferably driven by a single pump system.

[0056] The pump system includes at least one pump and / or a portion of a closed or open hydraulic line system and / or is connected to the hydraulic line system.

[0057] The advantage of using a common pump system to supply two or more hydraulic cylinders is that symmetrical force introduction can be achieved based on directly interconnected piping, which can be understood as connected containers. That is, the force introduction and / or mold clamping force loading of each hydraulic cylinder can be performed completely synchronously and with the same pressure profile.

[0058] If two or more clamping units are arranged close to each other, i.e. side by side and / or overlapping, it is particularly preferred that the first hydraulic line system is preferably connected to the first clamping force mechanism and / or the rapid stroke mechanism, and the at least one second hydraulic line system is preferably connected to the at least one second clamping force mechanism and / or the rapid stroke mechanism, so that the first hydraulic line system and the at least one second hydraulic line system can be interconnected.

[0059] For this purpose, at least one valve, particularly a switching valve, is provided between the first hydraulic pipeline system and the at least one second hydraulic pipeline system, through which the hydraulic conduits of the first hydraulic pipeline system and the at least one second hydraulic pipeline system can be interconnected.

[0060] When two or more hydraulic piping systems are interconnected, there exists a continuous flow of fluid and / or a closed hydraulic oil circuit within the interconnected hydraulic piping systems. That is, the first hydraulic piping system and the at least one second hydraulic piping system form a single system with interconnected hydraulic conduits.

[0061] When operating two or more clamping units using a single system with connected hydraulic conduits, a first clamping force mechanism and / or at least one rapid stroke drive and the at least one second clamping force mechanism and / or at least one rapid stroke drive can be supplied using one or more pump systems.

[0062] When operating two or more clamping units using a single system with connected hydraulic conduits, one or more valves, such as proportional valves, can be used to control or regulate a first clamping force mechanism and / or at least one rapid stroke drive and / or the at least one second clamping force mechanism and / or at least one rapid stroke drive.

[0063] The use of one or more pump systems and / or valves depends on different factors.

[0064] These factors may be, for example, mechanical and / or drive technology, electrical technology, control technology and / or safety-related and / or practical and / or economic properties, and / or dependent on the molding machine and / or molding die and / or material properties or the like.

[0065] In many cases, unintentional asymmetrical clamping force loading can be avoided by operating two or more clamping units using a single system with connected hydraulic conduits.

[0066] Especially in failure situations, such as when a valve, such as a proportional valve, fails, the parallelism of the first movable forming plate and the at least one second movable forming plate can be maintained substantially.

[0067] In the separate, independent operation of the first mold clamping unit and / or the at least one second mold clamping unit, the first mold clamping force mechanism and / or at least one rapid stroke drive and the at least one second mold clamping force mechanism and / or at least one rapid stroke drive can operate completely independently of each other.

[0068] In other words, in the individual operation of two or more mold-closing units, the first hydraulic piping system and the at least one second hydraulic piping system are preferably decoupled from each other.

[0069] A particularly preferred arrangement is that, especially when the first clamping force mechanism and the at least one second clamping force mechanism operate completely synchronously, i.e. in parallel, the first clamping unit and the at least one second clamping unit are mechanically kinematically coupled.

[0070] However, mechanical motion coupling is not mandatory.

[0071] The motion coupling of the machine can be achieved through at least one commonly supported molding die or through one or more mechanical coupling elements.

[0072] Mechanical coupling elements are, for example, flexible connecting elements (e.g., solid hinges and / or Flex-Link elements), tongue and groove systems (e.g., by means of slide keys), threaded connections (optionally with spring preload, e.g., by means of disc springs), or tightened thin connecting plates, which are mounted to the fixed and / or movable forming plates and / or mold-closing frames of the first and at least one second mold-closing unit.

[0073] Flexible connecting elements advantageously possess essentially elastic properties, thus allowing for temporary deformation and / or elastic action.

[0074] To ensure that the clamping axes of the first and at least one second clamping units are substantially parallel to each other, a mechanical motion coupling device is preferably provided, especially to achieve identical motion curves for the first and at least one second clamping units. Identical motion curves can be understood as the first and at least one second movable forming plates having the same start and end times and motion speeds.

[0075] In order to obtain the same motion curves for the first and at least one second movable forming plate, it is preferable to implement the motion coupling device of the machine such that the movable forming plates are arranged coplanarly with each other, that is, the movable forming plates are substantially in one plane.

[0076] In a state where the first and at least one second movable forming plates of an assembly having parallel oriented mold clamping axes are mechanically decoupled or coupled, the movable forming plates can be moved to different, substantially parallel positions. In other words, the distance between the first fixed forming plate and the first movable forming plate can be different from the distance between the at least one second fixed forming plate and the at least one second movable forming plate.

[0077] Instead of mechanical coupling using a fixed forming plate, there can be material-locked connections, for example, through bonding, welding, or brazing.

[0078] It is particularly preferred that the first and at least one second mold-closing unit be coupled to control or adjust.

[0079] The coupling control or regulation can be understood as the control or regulation parameters of the first mold clamping unit, such as the actual or theoretical values ​​of the clamping force, deformation, tension and / or pressure, and drive power parameters, affecting the control of the at least one second mold clamping unit, and vice versa.

[0080] In the mechanical motion coupling device of the first and at least one second mold clamping unit, the first and at least one second mold clamping unit are typically coupled to be controlled or regulated by a control or regulation unit, for example, based on a stroke measurement sensor.

[0081] It is particularly preferred that at least one movable separation device be provided between the first mold-closing unit and the at least one second mold-closing unit.

[0082] Movable separation devices are understood, for example, as movable separation protection devices.

[0083] When the first fixed forming platen, the first movable forming platen, the second fixed forming platen, and the second movable forming platen jointly support at least one forming mold, the separation device is located outside the first mold area of ​​the first mold closing unit and outside the second mold area of ​​the at least one second mold closing unit.

[0084] The mold area is understood as the area between the fixed forming platen and the movable forming platen, which can receive and / or support at least one forming mold.

[0085] The first mold-closing unit and the second mold-closing unit can also operate separately using the separation device. For this purpose, the separation device can extend between the first mold-closing unit and the second mold-closing unit.

[0086] The separation device can preferably be configured as a protective device for separation.

[0087] As a particularly preferred implementation variation, the first and at least one second mold-closing unit each include at least one, preferably four, tie rods or beams, which at least partially penetrate the fixed molding plate and / or the movable molding plate.

[0088] In the case of using at least one tie rod, it is feasible to have at least one tie rod positioned on the adjacent lateral edges of the fixed and / or movable forming plates of two adjacent mold clamping units with mold clamping axes oriented parallel to each other, so that the drive device generates a portion of the mold clamping force for the two mold clamping units by means of these tie rods.

[0089] Each tie rod, located on the adjacent lateral edges of the fixed and / or movable forming plates, passes through the first fixed forming plate and / or the first movable forming plate and / or the second fixed forming plate and / or the second movable forming plate, respectively.

[0090] In simple terms, two adjacent mold-forming units share one or more tie rods or push rods.

[0091] For two mold-closing units set close to each other, this means, for example, that instead of eight tie rods (where four tie rods are used in each mold-closing unit as is commonly done), only six tie rods are provided.

[0092] This can be advantageous from an economic point of view, for example, because the number of levers and corresponding drive mechanisms can be reduced.

[0093] Preferably, when using tie rods or crossbeams, pressure pads are used as a drive device for loading the mold closing force, that is, as a power stroke drive device.

[0094] As a preferred implementation variation, the first and second mold-closing units each include at least one, preferably exactly one, push rod that is centrally located.

[0095] As a preferred implementation variation, the first and second mold-closing units each include at least one crank mechanism.

[0096] Preferably, when using a push rod or crank rod, a hydraulic cylinder is used as the drive device for applying the clamping force. However, other drive devices are also entirely conceivable, such as a spindle drive device in the case of a crank rod mechanism.

[0097] It is particularly preferred that at least one traction device be provided when using a tie rod or crossbeam.

[0098] These traction devices are configured to pull the tie rod out of the mold area of ​​the first and at least one second mold clamping unit, so that the tie rod is outside the mold area. This creates free space, thereby enabling simplified installation and removal of the molding die, which is entirely advantageous in molds with fixed dimensions.

[0099] Preferably, the first clamping force mechanism and / or the at least one second clamping force mechanism are used to lock when the clamping force is applied.

[0100] The locking can be performed by a drive device and / or a locking mechanism.

[0101] A locking mechanism can be understood as, for example, a locking nut.

[0102] The components of the first and at least one second molding unit are preferably arranged in such a way that a flexible spatial arrangement of one or more syringes can be achieved.

[0103] The spatially flexible arrangement of the syringes is understood, for example, to mean that the at least one syringe can be positioned relative to the mold closing axis of the mold closing unit at all feasible angles, such as parallel to and / or perpendicular to the mold closing axis.

[0104] Here, at least one opening can be provided in the fixed and / or movable forming plates respectively, the opening being able to dock and / or press the at least one syringe onto the at least one forming mold.

[0105] The openings in the fixed forming plate and / or the openings in the movable forming plate are particularly understood as gaps, the inner walls of which include conical and / or cylindrical sections.

[0106] The at least one opening is preferably implemented such that the at least one syringe can be form-locked onto the fixed forming plate and / or the movable forming plate and / or the at least one forming mold.

[0107] The advantages of a spatially flexible arrangement of the syringe include, for example, the ability to optimize the injection process and / or at least one molding die and / or flexibly adapt to given conditions on the existing structure of the molding machine.

[0108] The optimization of the injection process by means of the flexible arrangement of the syringe can be understood, for example, by allowing for spatially flexible selection of the position on the at least one molding die (on which the injection is made), which can be particularly advantageous in the case of complex molding and casting geometry.

[0109] When the syringe can be flexibly positioned in space, it is feasible to optimize the geometry of the at least one molding die, which, for example, can optimize the clamping force loading and / or the quality of the molding die.

[0110] The flexible spatial arrangement of the syringes also allows for advantageous consideration of given structural conditions of the molding machine, such as the available space within the existing molding machine. Attached Figure Description

Detailed Implementation

[0112] Figure 1 A first embodiment of component 1 according to the invention is shown, wherein the first mold clamping unit 2 and the second mold clamping unit 8 (and possibly other mold clamping units) are arranged side by side and / or overlapping such that their mold clamping axes are oriented parallel to each other.

[0113] In this embodiment, the first mold closing unit 2 includes a first fixed molding plate 3, a first movable molding plate 4, and a first mold closing force mechanism 6, and the at least one second mold closing unit 8 includes a second fixed molding plate 9, a second movable molding plate 10, and a second mold closing force mechanism 11.

[0114] In this embodiment, the first mold closing unit 2 and the second mold closing unit 8 respectively include four pull rods 17 and a drive device 16, especially a power stroke drive device 26.

[0115] Instead of using the lever 17, at least one push rod 17 and / or a crank rod may also be provided.

[0116] also, Figure 1 The control or adjustment unit 7 is schematically shown, which is advantageously configured such that it controls or adjusts (open-loop control or closed-loop control) the first clamping force mechanism 6 and the second clamping force mechanism 11 together or separately from the first clamping force mechanism 6.

[0117] For example, two mold-closing units may include separate control or adjustment units 7, which are interconnected via data connections so that the mold-closing force can be applied synchronously.

[0118] In this embodiment, the control or adjustment unit 7 controls or adjusts the four drive devices 16 of the first clamping force mechanism 6, especially the power stroke drive device 26 and the four drive devices 16 of the second clamping force mechanism 11.

[0119] It should be mentioned that the control or regulation unit 7 is advantageously located directly on the machine. However, in principle, the control or regulation unit 7 may also be implemented as a computer server, which is located remotely from the machine. The control or regulation unit may also be implemented alternatively or additionally through distributed computing. Of course, a hybrid form is also conceivable.

[0120] If other mold-closing units are located next to the first mold-closing unit 2 and / or the second mold-closing unit 8, the control or adjustment unit in this embodiment also controls the drive device 16 and / or the rapid stroke drive device 25 of the mold-closing force mechanism of these other mold-closing units.

[0121] Figure 1 In particular, the drive device 16 and the tie rod 17 of the first clamping force mechanism 6 and / or the second clamping force mechanism 11 are shown, which are preferably used for the power stroke and therefore for the clamping force loading.

[0122] However, a drive unit 16 and a lever 17 for rapid travel can also be provided.

[0123] exist Figure 2 In the following description of the embodiments shown in Figures 8, to avoid repetition, the differences from the first embodiment will be discussed first. In other respects, the above description of the first embodiment is also applicable to the embodiments to be described below, provided that it is applicable.

[0124] Figure 2 A second embodiment of component 1 according to the invention is shown, wherein the first mold clamping unit 2 and the second mold clamping unit 8 share two of the total six drive devices 16 (especially the power stroke drive device 26) and / or pull rods 17, wherein these two pull rods 17 are located on the adjacent lateral edges of the first fixed molding platen 3, the second fixed molding platen 9, the first movable molding platen 4, and the second movable molding platen 10. That is, distinguished from Figure 1 The component 1 includes only six drive units 16 and / or levers 17, instead of eight.

[0125] exist Figure 2 The control or adjustment unit 7 is shown simplified in all subsequent figures and embodiments, wherein, for the purposes of clearer illustration, the connecting lines depicting the functional association between the control or adjustment unit 7 and the drive device 16 of the first clamping force mechanism 6 and the second clamping force mechanism 11 are omitted.

[0126] According to the present invention, the control or adjustment unit 7 includes, in any case and in all embodiments, at least the functional features already described.

[0127] Figure 3a–3d illustrates four embodiments of component 1 according to the invention, having a motion coupling device 12 with different mechanisms between the first mold clamping unit 2 and the second mold clamping unit 8.

Figure 4a This is the perspective view of component 1; Figure 4b It is a top view or side view of component 1.

[0134] Figure 4cA top or side view of component 1 is shown, wherein the separation device 13 is located outside the first mold area 14 and the second mold area 15, and the single molding mold 5 is supported by the first mold closing unit 2 and the second mold closing unit 8.

[0135] exist Figure 4c In the example, the first movable forming plate 4 and the second movable forming plate 10 are in a coplanar position and the forming mold 5, which is supported by both, has a right parallelepiped shape.

[0136] Figure 5a and 5b An embodiment of component 1 according to the invention is shown, wherein a third mold-closing unit is disposed adjacent to the first mold-closing unit 2 and the second mold-closing unit 8, and all three mold-closing units jointly support a molding die 5. Here, Figure 5a It is the perspective view of component 1 and Figure 5b It is a top view or side view of component 1.

[0137] In this embodiment, the distance between the first fixed molding platen 3 and the movable molding platen 4 in the first mold closing unit 2 is different from the distance between the second fixed molding platen 9 and the second movable molding platen 10 in the second mold closing unit 8 and / or the distance between the third fixed molding platen and the third movable molding platen in the third mold closing unit, and the shape of the molding mold 5 supported by the common platen is stepped.

[0138] Because Figure 5a and 5b In the embodiment, the unique stepped molding die 15 is supported by the first mold closing unit 2, the second mold closing unit 8, and the third mold closing unit, so the first movable molding platen 4, the second movable molding platen 10, and the third movable molding platen move synchronously.

[0139] However, if multiple molding dies 15 are supported by the first mold clamping unit 2, the second mold clamping unit 8, and possibly other mold clamping units, then the movable molding platen that supports only one molding die 15 moves synchronously.

[0140] Instead of each mold-closing unit, the mold-closing unit may include its own fixed molding plate, or it is conceivable that multiple mold-closing units share a fixed molding plate.

[0141] The at least one movable forming platen of the at least one mold clamping unit, which supports only one forming mold, can move asynchronously relative to the movable forming platen of the other mold clamping unit, which can jointly support one forming mold.

[0142] Figure 6a and 6bA perspective view of an embodiment of component 1 according to the invention is shown, having a traction device 18 disposed on some or all of the tie rods 17.

[0143] Figure 6a The following positions are shown, in which the pull rod 17 is located in the first mold area 14 and the second mold area 15.

[0144] Figure 6b The following positions are shown where the pull rod 17 is partially pulled out from the first mold area 14 and / or the second mold area 15.

[0145] The components of the traction device 18, particularly the upper tie rod 17, are suitable to simplify the loading and / or unloading of the at least one molding die 5.

[0146] Figure 7a –7f shows a perspective view of six embodiments of the component 1 according to the invention, having a plurality of syringes 19 arranged in different spatial arrangements.

[0147] Here, the syringe 19 can be arranged at all feasible angles relative to the mold closing axis of the first mold closing unit 2 and / or the second mold closing unit 8.

[0148] Furthermore, the syringe 19 can be configured such that it can be pressed against the at least one molding die 5 by means of openings provided in the first fixed molding plate 3 and / or the second fixed molding plate 9 and / or the first movable molding plate 4 and / or the second movable molding plate 10 and / or through the first mold region 14 and / or the second mold region.

[0149] Figure 7a An example of a component 1 is shown, wherein the syringes 19 are respectively disposed on the first fixed molding platen 3 of the first mold closing unit 2 and the second fixed molding platen 9 of the second mold closing unit 8 in a direction parallel to the mold closing axis and can be pressed against the at least one molding die and / or the molding platen itself by means of an opening provided for this purpose.

[0150] Figure 7b An example of a component 1 with three syringes 19 is shown, wherein two syringes 19 can be pressed into openings in the first fixing platen 3 of the first mold clamping unit 2 and the second fixing platen 9 of the second mold clamping unit 8, respectively, and pressed in a direction parallel to the mold clamping axis, and one of the three syringes 19 is inclined relative to the mold clamping axis of the second mold clamping unit 8.

[0151] Figure 7cAn example of a component 1 with four syringes 19 is shown, wherein one syringe 19 can be pressed against an opening in a first fixed molding plate 3, one syringe can be pressed against an opening in a second fixed molding plate 9, one syringe 19 can be pressed against an opening in a first movable molding plate 4, and one syringe 19 can be pressed against an opening in a second movable molding plate 10, and all four syringes 19 are arranged parallel to the mold closing axis.

[0152] Figure 7d An example of a component 1 with three syringes 19 is shown, wherein two syringes 19 are pressed against openings in the first fixed molding platen 3 and the second fixed molding platen 9 and are arranged parallel to the mold closing axis, and one syringe 19 is oriented perpendicular to this and vertically relative to the mold closing axis of the first mold closing unit 2 and / or the second mold closing unit 8 and is pressed directly onto the molding die 5 through the first mold area 14 and / or the second mold area 15.

[0153] Figure 7e An example of a component 1 consisting of three syringes 19 is shown, wherein two syringes 19 are respectively oriented parallel to the mold closing axis and disposed on openings in the first fixed molding plate 3 and the second fixed molding plate 9, and one syringe 19 is disposed in a horizontal direction and perpendicular to the mold closing axis of the first mold closing unit 2 and / or the second mold closing unit 8.

[0154] Figure 7f An embodiment of a component 1 having four syringes 19 is shown, wherein two syringes 19 are respectively disposed in a direction parallel to the mold closing axis and at least one opening of the first fixing platen 3 of the first mold closing unit 2 and / or the second fixing platen 9 of the second mold closing unit 8.

[0155] The syringe 19 can also be positioned on a separate opening.

[0156] In summary, any other arrangement of the syringe 19 is feasible.

[0157] Figure 8a and 8b An embodiment of component 1 according to the invention is shown, wherein not only is a drive device 16 in the form of a power stroke drive device 26 for loading the mold clamping force shown, but also a rapid stroke drive device 25 for implementing rapid stroke movement is shown.

[0158] In this embodiment, the first mold-closing unit 2 and the at least one second mold-closing unit 8 each include at least two rapid stroke drive devices 25.

[0159] Figure 9a-d shows four examples of hydraulic circuit diagrams for components according to the invention, particularly with a rapid stroke drive 25 for implementing rapid stroke movements.

[0160] All subsequent circuit diagrams involve two mold-forming units arranged close to each other, i.e., side-by-side or overlapping. However, the principle of these circuit diagrams can be transferred to any number of mold-forming units arranged close to each other, i.e., side-by-side and / or overlapping.

[0161] Figure 9a A circuit diagram is shown for two mold-closing units arranged close to each other, each having a hydraulic drive 16, particularly a rapid stroke drive 25, wherein the hydraulic drive 16 is understood in particular as a hydraulic cylinder.

[0162] Since this embodiment specifically relates to a circuit diagram for at least one rapid stroke movement, the drive device 16 is preferably a rapid stroke drive device 25.

[0163] Rapid stroke drive devices are typically used to implement the rapid movement or shifting of movable forming plates in the sense of the mold closing and opening motion of the mold closing unit.

[0164] Alternatively, the drive unit 16 may be a power stroke drive unit 26 configured for loading the mold clamping force.

[0165] During the power stroke, the movement or displacement of the forming plate is typically very small or negligible.

[0166] It should be mentioned that the movable forming platen, loaded by a hydraulic cylinder with clamping force, is not... Figure 9a Any of the -d options are shown in the diagram.

[0167] exist Figure 9a In the embodiment, the first mold closing unit 2 and the second mold closing unit 8, and therefore the first movable forming platen 4 and the second movable forming platen 10 are in a powerless position.

[0168] No powered stroke occurs in the powerless position. However, in that position or... Figure 9a Rapid travel may be occurring in the wiring.

[0169] Figure 9a The circuit diagram also represents separate, independent operations.

[0170] In other words, the first movable forming plate 4 and the second movable forming plate 10 operate independently of each other in this example.

[0171] This allows for independent adjustment of the first clamping force mechanism 6 of the first clamping unit 2 and / or the movement direction and / or speed of the at least one rapid stroke drive device 25 and the second clamping force mechanism 11 of the at least one second clamping unit 8 and / or the at least one rapid stroke drive device 25.

[0172] exist Figure 9a In particular, a first hydraulic cylinder pair in the form of a rapid stroke drive device 25 is connected to the first hydraulic pipeline system 20, and a second cylinder pair in the form of a rapid stroke drive device 25 is connected to the second hydraulic pipeline system 21.

[0173] Furthermore, all drive units 16 here, especially the rapid stroke drive unit 25, include a single pump system 22.

[0174] Figure 9a A switching valve 27 is also shown, which is used for coupling the first hydraulic line system 20 and the second hydraulic line system 21.

[0175] This means that the rapid stroke drive device 25 of the first mold closing unit 2 and the rapid stroke drive device 25 of the second mold closing unit 8 can be coupled or controlled independently of each other.

[0176] Preferably, a switching valve 27 between the first hydraulic piping system 20 and the second hydraulic piping system 21 is configured for separate, independent operation, as in... Figure 9a The state shown is either energized or switched on.

[0177] The current-free state of the switching valve 27 in the coupled state is advantageous from the perspective of mechanical and / or drive technology and / or safety technology.

[0178] exist Figure 9a In the circuit diagram, the switching valve 27 is adjusted in this way so that the first hydraulic pipeline system 20 and the second hydraulic pipeline system 21 are in a decoupled state.

[0179] That is, the preferred switching valve 27 is energized here.

[0180] Generally, it is feasible not only to couple two hydraulic piping systems, but to couple any number of hydraulic piping systems, wherein the number of hydraulic piping systems preferably corresponds to the number of mold closing units arranged close to each other.

[0181] In all subsequent descriptions of the hydraulic circuit diagram examples, to avoid repetition, we will first discuss the... Figure 9a The examples shown are different. That is, for any usage, it applies... Figure 9a The explanation also applies to the examples that follow.

[0182] Figure 9b Another example of a hydraulic circuit diagram of a component according to the invention in stand-alone operation is shown.

[0183] Different from Figure 9a The route map in Figure 9b The circuit diagram includes two pump systems 22.

[0184] Preferably, a pump system 22 is configured for the first hydraulic line system 20 and the second hydraulic line system 21, respectively.

[0185] However, the at least one pump system 22 may also be located at any position on the first hydraulic piping system 20 and / or the second hydraulic piping system.

[0186] Because the first mold-closing unit 2 and the second mold-closing unit 8 are also present in this embodiment, as already... Figure 9a The circuit diagram shows that it is operating independently, so the switching valve 27 between the first hydraulic system 20 and the second hydraulic system 21 is adjusted such that the first hydraulic system 20 and the second hydraulic system 21 are in a decoupled state.

[0187] Therefore, the first hydraulic piping system 20 and the second hydraulic piping system 21 are preferably supplied by a separate pump system 22.

[0188] Here, the switching valve 27 is preferably energized even in the decoupled state.

[0189] A pump system switching valve 28 is provided between the two pump systems 22, through which the two pump systems 22 can be connected to each other.

[0190] In contrast to the switching valve 27, which is preferably used for interconnection of piping systems 20, 21, the at least one pump system switching valve 28 is preferably used for interconnection of pump systems 22.

[0191] In this embodiment, the pump system switching valve 28 is preferably energized, thereby decoupling the pump system 22.

[0192] Figure 9c Showing as in Figure 9b The diagram shows the hydraulic circuit of the assembly according to the invention, featuring the same switching elements. However, these switching elements are adjusted such that the first mold-closing unit 2 and the second mold-closing unit 8 operate in parallel.

[0193] In other words, the first mold clamping unit 2 and the second mold clamping unit 8 are completely synchronously controllable or adjustable, and the first movable forming platen 4 and the second movable forming platen 10 are synchronously movable and / or can be loaded with mold clamping force.

[0194] Here, preferably, the rapid stroke drive device 25 of the first mold closing unit 2 is supplied through the first hydraulic pipeline system 20 and controlled or regulated by valve 23, especially proportional valve 24, and the rapid stroke drive device 25 of the second mold closing unit 8 is supplied through the second hydraulic pipeline system 21 and controlled or regulated by another valve 23, especially proportional valve 24.

[0195] In addition, two switching valves 27 are preferably provided between the first hydraulic pipeline system 20 and the second hydraulic pipeline system 21, and a pump system switching valve 28 is provided between the two pump systems 22.

[0196] exist Figure 9c In the embodiment of the circuit diagram, the switching valve 27 between the first hydraulic line system 20 and the second hydraulic line system 21 is in a coupled and preferably current-free state, so that all existing rapid stroke drive devices 25 are coupled to each other.

[0197] Furthermore, the pump system switching valve 28 between the pump systems 22 is adjusted in such a way that the pump systems 22 are interconnected.

[0198] It can also be seen here that all the existing rapid stroke drive units 25 are controlled or regulated by a single valve 23 (shown on the left), especially a proportional valve 24, through a coupled piping system.

[0199] All rapid-stroke drive units 25 can also be supplied by a single pump system 22. Therefore, the pump system switching valve 28 between the two pump systems 22 must be adjusted to a decoupled state.

[0200] The parallel operation of the rapid stroke drive 25 of the first mold closing unit 2 and the rapid stroke drive 25 of the second mold closing unit 8, which has a unique pump system 22, are preferably used when the required speed of the hydraulic cylinder is low.

[0201] Controlling all hydraulic cylinders by a single valve 23, especially a proportional valve 24, has the advantage that only one proportional valve 24 is technically relevant to the entire movement of the first mold clamping unit 2 and the second mold clamping unit 8, and therefore the setting and / or control or adjustment is simpler.

[0202] On the other hand, in control or regulation by means of a single valve 23, especially a proportional valve 24, the valve 23, especially the proportional valve 24, must be selected accordingly based on a large number of hydraulic cylinders to be controlled.

[0203] This could further include disadvantages, namely, poor control resolution, i.e., accuracy, during very slow movements and / or during the separate operation of the first mold-closing unit 2 and the second mold-closing unit 8.

[0204] Figure 9d Another example of a circuit diagram is shown for parallel operation of two mold-closing units positioned close to each other, where the disadvantages of using a single large valve 23, and especially a proportional valve 24, can be circumvented in parallel operation.

[0205] A circuit diagram is shown here, in which the first hydraulic piping system 20 and the second hydraulic piping system 21 are coupled to each other by means of two switching valves 27. The first hydraulic piping system and the second hydraulic piping system can be supplied by two pump systems 22, and the first clamping force mechanism 6 and / or rapid stroke drive device 25 of the first clamping unit 2 and the second clamping force mechanism 11 and / or rapid stroke drive device 25 of the second clamping unit 8 can be controlled by means of at least two valves 23, especially proportional valves 24.

[0206] exist Figure 9d The advantage of the circuit diagram is that the valve 23, especially the proportional valve 24, can be optimized for the corresponding hydraulic piping system and / or the corresponding clamping force mechanism and / or rapid stroke drive.

[0207] In other words, for example, the proportional valve 24 shown on the left can be optimized for the rapid stroke drive 25 of the first hydraulic piping system 20 and / or the first clamping force mechanism 6 and / or the first clamping unit 2.

[0208] Similarly, the proportional valve 24 shown on the right can be optimized for the rapid stroke drive 25 of the second hydraulic piping system 21 and / or the second clamping force mechanism 11 and / or the second clamping unit 8.

[0209] By optimizing valve 23, especially proportional valve 24, in parallel operation, the same speed and / or the same clamping force curve and / or clamping force process can be obtained for all hydraulic cylinders.

[0210] exist Figure 9d In this way, switching valve 27 is switched so that the first hydraulic pipeline system 20 and the second hydraulic pipeline system 21 are coupled, which preferably corresponds to the position without current.

[0211] This can include the advantage of ensuring hydraulic compensation between the first hydraulic line system 20 and the second hydraulic line system 21 in the event of disturbances, such as when valve 23, especially proportional valve 24, fails.

[0212] Because the switching valve 27 between the first hydraulic piping system 20 and the second hydraulic piping system 21 may include important driving technology and / or mechanical and / or safety technology significance in parallel operation, it is preferable to provide electrical monitoring of the switching valve 27.

[0213] Advantageously, all valves 23, especially proportional valves 24 and / or switching valves 27 and / or pump system switching valves 28, are electrically monitored.

[0214] For example, controlled operation can be introduced in the event of disturbance by utilizing electrical monitoring of the valve 23, especially the proportional valve 24 and / or the switching valve 27 and / or the pump system switching valve 28.

[0215] Figure 10 An example of a hydraulic circuit diagram for a component according to the invention is shown, particularly having a power stroke drive 26 for implementing the power stroke.

[0216] In this example, the first hydraulic line system 20 and the second hydraulic line system 21 are supplied by a pump system 22 and coupled to each other by means of a switching valve 27, wherein each system or each clamping force mechanism 6, 11 includes four drive units 16 or power stroke drive units 26 respectively.

[0217] Here, the sum of the hydraulic drive device 16 of the individual mold clamping unit, especially the power stroke drive device 26, is understood as a single mold clamping force mechanism.

[0218] In other words, the four hydraulic drive devices 16, i.e. the four hydraulic cylinders of the first mold clamping unit 2, correspond to the first mold clamping force mechanism 6, and the four hydraulic drive devices 16 of the second mold clamping unit 8 correspond to the second mold clamping force mechanism 11.

[0219] This circuit diagram relates to the control or adjustment of the power stroke drive device 26, such as the pressure pad.

[0220] The route map is in Figure 9a The examples shown in -d and 10 are not a complete list of feasible variations.

[0221] Other wiring can also be envisioned, as long as it enables the proper operation of two or more mold-closing units positioned close to each other.

[0222] Here, from a hydraulic point of view for use in circuit diagrams, the same principle generally applies to both rapid stroke and power stroke.

[0223] The circuit diagram should at least meet the safety technology aspects, but may depend on very different requirements and / or target settings, such as given conditions of the molding casting machine and / or mold and / or production process and / or material requirements, etc.
