摘要： The invention relates to a method and a removal device for the automatic removal of injection moulded parts from the half moulds (10, 11) of injection moulding machines. By installing additional vacuum storage element (61) in consumer proximity, the necessary vacuum is available for each removal in an additional area, independent from pressure variations in the vacuum system. Before the beginning of each removal, the available system is monitored by sensor means (70, 71, 72) and by maintaining a vacuum-limit value a movement authorisation is transmitted to the removal robot (30). A pressure switch threshold value is also determined for the vacuum which is adjusted in close proximity to the suction cup during the removal of the injection moulded parts (1) by the suction cups (44) of the removal robot (30). If the pressure switch threshold value is reached as a result of sufficient closeness of the injection moulding parts (1) to the suction caps (44), the removal robot (30) is authorised, by means of a machine control, to carry out additional movements. The pressure switch threshold value can be set as a percentage of the start vacuum at the beginning of each removal and as a result, the time and removal safety for each part or production charge are optimised.

摘要： The invention relates to an injection screw drive for a plastic injection molding machine comprising axes (A1, A2) respectively provided for the rotative and for the axial motion of the injection screw (4). According to the invention, the injection screw drive has at least one double rack rail overdrive for effecting the axial motion. The injection worm drive is configured as a gear combination having at least two drive motors (18, 44) and an output axle. The gear combination has, as a core, a gear block with a gear casing (42), to which at least two reducing gears are connected that effect the rotative and the axial motion of the injection screw (4). This enables the entire machine to be provided with a short and compact structure insofar as this concerns the injection aggregate. According to a second embodiment, both drives have separate housings. The entire injection unit rests, in a known manner, on the machine stand (33) via guide rails (32) such that it can be displaced.

摘要： The invention relates to a novel method for producing precision parts, especially flat optical data carriers. According to the inventive method, the embossing procedure is program-controlled on the basis of the path function of an electromechanical or hydraulic drive of the driven mold half. When a servomotor is used, the internal path signal thereof can be directly used for calculating the path function or for operating the program control. The novel method allows for a complete speed control of the embossing phase. All factors that can be mechanically influenced from the exterior are detected in more detail for the conditions before and during the embossing phase, thereby allowing for an optimum precision and reproducibility.

摘要： The invention relates to the production of preforms (10) for PET bottles in batch quantities. According to the invention, the mould nests are arranged in the injection moulds in a specific manner, thereby increasing the number of cooling positions in an after cooler (19, 40). The inventive device is provided with controllable/adjustable movement means for the two coordinates (x, y; y, z) of the transfer plane of the after cooler (19, 40), enabling the after cooler (19, 40) to be cyclically positioned with respectively free cooling positions in the fixed arrangement of moulded objects (10) in the moulds, whereby a maximum density of cooling positions can be obtained in said after cooler (19, 40) . The invention enables four times more cooling positions to be obtained, especially when arranged in a staggered manner, in comparison with the number of mould nests in said mould, in addition to allowing the number of mould nests to be increased to 144 and more.

摘要： The invention relates to false twist nozzles by means of which one or more threads are impinged upon with an intensive twisting flow. At least one part of the conventional mechanic false twist producing devices can be replaced by optimising the air channels by means of a powerful twisting flow. A twist insertion plate is the new central element. A false twist nozzle is provided with at least one plate as the twist insertion plate having a continuous yarn channel component and a tangential channel and at least one element having an air supply device that extends in parallel in relation to the axis of the yarn channel, corresponds to the twist insertion plate and flows into the acceleration channel. The inventive solution enables a plurality of embodiments for a single thread or yarn sheet treatment. S and Z twist can be freely combined. The false twist nozzles can be used as subassemblies block by block or individually.

摘要： The invention relates to a method for controlled driving of the cast axle (8) of pressure die casting machines, comprising a drive piston (15), wherein the forward and return motion of the piston (15) is carried out in a controlled manner. The invention is characterized in that the oil flow or oil pressure on the piston rod side is controlled/regulated by a pump (30) and additionally by a throttle valve (103) working in parallel at least during the filling phase, especially during the fast forward motion part.

摘要： The aim of the invention is to produce reasonably-priced, top-quality twisting disks for false twisting of textile threads by carefully selecting the material and by virtue of the design of the hub and collar. The chosen material is a composite material, especially polyurethane, consisting of PPDI and polycarbonate and preferably filled with aramid. The hub is produced from hard PTU. This has two advantages. The collar material must meet extremely tough requirements and is the most expensive of all. It can be used in small amounts in an optimum manner, geared towards twisting. The inventive concept enables both functional parts - hub and collar - to be manufactured in a single-step or two-step injection moulding process.

摘要： The invention relates to a method and a device for the secondary treatment and the cooling of preforms (10) once they have been removed from the open mould halves (18, 9) of an injection moulding machine. The preforms are removed from the open moulds (18, 9) while still hot, by means of water-cooled cooling sleeves (21) of a removal device (11), and are subjected to intensive cooling during the duration of an injection moulding cycle. Both the entire inner side and the entire outer side of the blow-moulded part (10) are subjected to intensive cooling. Secondary cooling is then carried out, the duration thereof being equal to a multiple of the duration of an injection moulding cycle. After being removed from the casting moulds, the preforms are dynamically introduced into the cooling sleeves (21) until they fully touch the walls thereof. The inner cooling is carried out in a time-delayed manner.
