Described is an intermediate plate (6) for fastening to a platen (1, 2) of an injection-moulding machine and for receiving a mould half (4a, 4b) of an injection-moulding tool (4). In order, in the case of standard platens, to compensate sagging of the latter and to avoid gaping of mould hollows (5b), it is proposed according to the invention that the intermediate plate (6) has, between a central region (7) and external peripheral regions (9a, 9b), one or more regions (8a, 8b) that are elastically deformable under the action of a closing force, for example empty spaces (11a, 11b, 23) in the interior of the intermediate plate (6). Under the action of a closing force, the intermediate plate (6) is squeezed together in the deformable regions (8a, 8b) by the peripheral regions (12a, 12b) of the injection-moulding tool, whereas in the central region (7) the intermediate plate (6) is not squeezed together. As a result, in spite of sagging of the platens (1, 2) themselves, gaping of the mould halves (4a, 4b) in the central region (7) is prevented as a whole.

METHOD AND DEVICE FOR CONTROLLING A LINEAR MOTION AXIS
The invention relates to a method and device for controlling a linear motion axis, particularly of the injection screw (43) or a melt piston for an injection molding machine. Said device comprises a hydraulically driven piston (45) having a piston chamber (A) and a rod chamber (B). According to the solution proposed by the invention, at least one process phase is controlled/regulated by means of two parallel proportional valves, an injection valve (1) and a metering valve (2). The two proportional valves can be connected in parallel or in combination. The control/regulation of the driven piston (45) preferably uses digital technology. An enormous reduction in energy consumption and smooth transitions between the process phases are achieved with a hydraulic linear drive.

PROCESS FOR THE MOULD CLOSURE OF AN INJECTION MOULDING MACHINE, AND MOULD CLOSURE
The invention relates to a process for the mould closure of an injection moulding machine comprising a supporting element (1), a moveable tool clamping plate (13), 5-point toggle levers and a hydraulic drive (25) for the crosshead (2), and also to a mould closure. The crosshead drive is arranged between the supporting element (1) and the moveable tool clamping plate (13). The individual 5-point toggle levers are each embodied with a toggle lever (9), a mould movement lever (11, 11') and an expanding bracket (6). The movements for the mould closure are transmitted to the toggle levers (9) via expanding brackets (6). The expanding brackets (6) act in a central region of the toggle levers (9). The toggle levers (9) are embodied as articulated forks (20, 21), wherein the expanding brackets (6) act in a transverse web (22) of the articulated forks. The principal reaction forces of the mould forces are transmitted symmetrically to the supporting element (1) without lateral forces. The solution makes it possible to achieve a maximum pivot angle for the toggle levers (9), to use long toggle levers (9) and to achieve a maximum opening stroke for the mould halves.
The invention relates to an apparatus and a process for injection moulding machines having a tool clamping plate (3). The large mould closure forces deform or deflect the nozzle-side tool clamping plate, in particular, by up to one millimetre. This results in large mechanical loads on the injection moulding tools. The novel invention proposes that the nozzle-side and/or the moveable tool clamping plate (3) be at least partially deflected or elastically deformed on a processing table in the same way as is caused by the mould closure forces and that facing be carried out under the force of deformation in the region of the tool clamping face (17).

PROCESS AND DEVICE FOR PRODUCING AND AFTER-COOLING SLEEVE-SHAPED INJECTION-MOULDED PARTS
The invention relates to a process for producing and after-cooling sleeve-shaped injection-moulded parts, in particular preforms (10), by means of an injection moulding machine having an injection side and also a mould closure side which has a removing gripper (11), a transfer gripper (12), a cooling block (19) for after-cooling and also a removal means (20). The removal and at least the first phase of the after-cooling of the preforms (10) are effected by means of a removing gripper (11) which is held on an outer support. The injection-moulded parts (10) are arranged in the cooling block (19) in a compressed state in relation to the arrangement in the transfer gripper (12) as a result of an offset series arrangement, and the cooling block (19) can therefore hold a number of injection-moulded parts (10) of several cycles. The transfer gripper (12) is controlled by means of a longitudinal movement with respect to the machine axis under the cooling block (19) and the latter is moved and positioned transversely with respect to the machine axis in order to select the correct rows.
The invention relates to a device and a method for aftercooling preforms (6) that are removed from a multiple injection mold in an unstable shape. According to the invention, air cooling for the external side of the open end of the preform (6) is integrated into the water-cooled cooling jackets (1). Particularly in special types of preforms, the zones that are not supported in the cooling jackets (1) are externally cooled using cold generated by expanding compressed air from the moment the preforms begin to be transferred from the open molds (78, 79) to the removing or cooling jackets (1). Said novel solution makes it possible to ensure top quality, especially also in terms of the dimensional stability and absence of compressed points resulting from the effect of a calibration process in the cooling jackets (1) and the handling process in the aftercooling zone.
The invention relates to a device and a method for finishing and calibrating preforms (10) which are removed from a multiple injection tool in an unstable shape, and proposes an air cooler integrated into the water cooled cooling jackets (21) for the outer side of the open end face of the preform (10). Particularly in the case of special preform varieties, the areas which are unsupported in the cooling jackets (21) can be prestrengthened on the outside, from the beginning of the transfer from the open molds (8, 9) to the removing and/or cooling jackets, by means of a cooling which uses cooling air or deep cooled air. With the novel solution, the highest quality can be assured, in particular with respect to dimensional stability and the absence of pressure points under load, by means of a calibration in the cooling jackets (32) and the treatment in the area of the aftercooling.
The novel invention relates to a method and an apparatus for controlling one or more machines or a production cell with repeatable sequences using a machine controller, and to an operating unit in the form of a man-machine interface (MMI). The novel invention proposes making at least some of the operative control inputs for machine movement using haptic keys which can be programmed for their function and are applied to a screen and/or tactile touchscreen keys which can be seen and sensed, for example with an edge which can be sensed, with a respective associated screen field. The operator is thus provided with a guide function for operation, whether by the fact that he haptically senses the keystroke, for example via snap domes, or by the fact that he only tactually feels an edge around the screen key.

METHOD AND DEVICE FOR THE ASSEMBLY AND DISASSEMBLY OF A PREPLASTICIZING SPINDLE
The invention relates to a method and a device for the assembly and disassembly of the preplasticizing spindle (1) of a ram or drive end (11) of a worm drive system of an injection molding machine by means of a clamp coupling (10). The worm drive system is designed for a controlled linear and rotary movement of the preplasticizing spindle (1). The coupling occurs by means of clamping agents which are preferably in the form of mechanical clamp coupling (10), wherein the rotary driving power and the worm return force are transferred via frictional engagement, and the axial injection force is transferred via an end stop. The assembly and disassembly procedure is supported by being controlled by the worm drive system. The preplasticizing spindle (1) can also be developed and coupled or decoupled as a heat-shrinkage connection or as a hydraulic tension system (23), wherein the preplasticizing spindle (1) is introduced during coupling to the end stop.

METHOD AND INJECTION-MOULDING MACHINE WITH MODULAR STRUCTURE
The invention relates to a method and an injection-moulding machine with modular structure. In the solution proposed, to optimize logistics, in particular transport, the design and the construction of at least the mould-clamping mechanism side (7) and the injection system side (8) of the machine are modular. There are central unitary mounting and coupling interfaces (13 and 14 or 15, 15', 15') by way of which a mould-clamping module (1), a system module (16) and a drive module (17) are connected. The three modules can be selected freely from appropriate ranges of mould-clamping modules and system modules and drive modules.
The invention relates to an auxiliary device and a method for finishing and calibrating preforms (10) that are removed from a multiple tool in an unstable shape, the calibration process being performed with the aid of compressed air immediately after removing and withdrawing the preforms (10) from the multiple tool. Nipples that can be inserted into the preforms (30) are provided with expandable pressing rings or sealing rings (56) in order to seal the interior of the blow-molded part of the preforms (10). The compressed air is introduced via the nipples (30), the sealing process being performed by radially expanding the pressing rings or sealing rings (56) in analogy to the closing process of thermoses, thus protecting the preforms (10) from adverse forces. The sealing point can be randomly selected in the transition zone from the threaded part to the blow-molded part of the preforms (10). The invention allows the interior of the blow-molded part (43) to be optimally sealed without affecting the form stability and dimensional stability of the preforms (10). In special types of preforms, the areas that are not supported in the cooling sleeves can be preconsolidated on the outside by means of cool air from the moment the preforms are transferred to the removing sleeves or cooling sleeves.
The invention relates to a method and a device for closing the moulds (11, 12) of an injection moulding machine by means of a crank mechanism (5). According to the invention, the complete crank mechanism (5) with a hydraulic cylinder (31) is arranged in the machine between the drive support plate (1) and the moving tool clamping plate (2). The hydraulic cylinder (31) is connected to the drive support plate (2) by means of a piston rod (32) and engages centrally with the crank mechanism at a cross-head (20).
