Definitions

  • the invention relates to a blow molding machine with a closing unit which has mold halves attached to clamping plates or closing plates and is movable between an extrusion head and a calibration device, which preferably contains a calibration cylinder whose piston rod is connected to a sliding plate to which one or more blowing mandrels are attached , which are preferably equipped with a cutting ring which is pressed during calibration against a cutting plate of the blow mold.
  • the calibration cylinder and piston rod system can be replaced by other suitable force introduction elements.
  • the general structure of such a system in its interaction of the movements is well known and delivered thousands of times by the most diverse blow molding machine manufacturers to the market, which is why in this regard is omitted in this application to a detailed description.
  • a calibration device with calibration cylinder and piston rod is only one embodiment and can also by other force introduction means such.
  • B. threaded roller drives, toothed belt drives or the like can be displayed.
  • a tubular preform is first produced from an extrusion tool, the blow mold closes and the closing unit is moved into the position of the calibration device.
  • the blow pin (s) are introduced into the hose held by the mold halves and under compressed air becomes the container defined by the blow mold blown out. This often takes place at the point which later also represents the filling opening of the finished container.
  • the sealing surface must be smooth and level.
  • the so-called cutting ring which can be considerable with great force, which may be considerable, for example in multiple domes against a corresponding elaborated and hardened counter surface of the blow mold , the so-called cutting jaw, is pressed.
  • the waste is additionally pre-punched or separated from the upper edge of the filling opening. This procedure has long been common and has proven itself.
  • the quality of the sealing surface of the container thus produced and the life of the cutting ring and cutting jaw depend inter alia on how the components of the blow molding machine involved in the frictional connection behave under load. Even slight eccentricities or a change in the position of the blow mandrel to the blow mold under load lead to increased wear of the contact surfaces and to deficiencies in the containers produced.
  • the calibration force is e.g. exerted via a cylinder 1, the piston rod 2 is centrally connected to a sliding plate 3, which is usually guided over spars 6.
  • the sliding plate 3 carries the blowing mandrel or 4, which has the above-mentioned cutting ring 5 behind its tip.
  • the system cylinder guide rails slide plate Blasdom (e) is fixedly mounted with a cantilever 7.
  • This entire system is commonly referred to as a "calibration" and is firmly connected to a machine bed 8, which also, mounted on bars 12, the closing frame 1 1 In the closing frame 1 1, a bar system 13 is accommodated, which carries the clamping plates 10, 10 ', on which in turn the mold halves 9, 9' are clamped in. These mold halves 9, 9 'have the cutting bar 14
  • a pressure piece 15 is mounted on the clamping plate 10 directed towards the machine bed, which is supported on a roller block 15 '.
  • FIG. 2a shows the same view into the system as FIG. 1.
  • an upper hook 16 and below it on the outer clamping plate 10 'a lower hook 17 are fastened.
  • FIG. 2b shows the schematic design of such a hook system.
  • the forces acting on the mold halves by the cylinder 1 of the calibration device are considerable and can be very significant depending on the size of the mold halves and the number of blowing mandrels.
  • the components that serve to accommodate the calibration, as well as the machine bed that carries these components in high strength and associated high cost Due to the very heavy construction, accessibility to the mandrel area and to the extrusion head or heads is very difficult and difficult to achieve for setup work.
  • the invention was therefore based on the object, on the one hand to maintain the advantage of a compact, predictable power system, but on the other hand to eliminate the disadvantages mentioned.
  • Figure 3 is a view into the system as already used in Figure 1 and Figure 2a with a closed system of platens 10, 10 'and the supported mold halves 9, 9';
  • FIG 5 shows a view which is rotated relative to FIGS. 3 and 4 by 90 °.
  • the representation of the molding system and the calibration device with the exception of the cantilever 7 was omitted.
  • a guide rail 22 is screwed on which a carriage 23 is slidably mounted. Again, only one embodiment is shown. Any other management possibilities are also conceivable.
  • a frame 24 is screwed firmly, which carries the U-shaped rail 21 and two intermediate pieces 25.
  • the slide plate 18 is always kept in relation to the intermediate piece 25 from the side at the same distance.
  • two hooks 26 are firmly screwed, the pieces 25 slide in the mold opening direction in the insects ⁇ .
  • the cantilever 7 is supported by an attached on the closing frame 1 1 adjustable in height Bocksystem 27.
  • the cantilever 7 which, as already described, the cylinder 1 with piston rod 2, the slide plate 3 with the or the unfolded Blasdornen 4 and the guide rails 6 carries, is designed as intrinsically stable carrier.
  • the power flow introduced by the cylinder 1 via piston rod 2 and mandrel 4 tries to contact the cutting sleeve 5 against the cutting plate 14 in the calibration position of the closing frame 1 1 with closed mold halves as shown in FIG. 3, push away the cantilever upwards, which is the Bocksystem 27 prevented.
  • a force is going in the direction Platen 10, 10 ', covered with the mold halves 9, 9' which would greatly burden the guide systems.
  • Fig. 4 shows the mold halves 9, 9 'supporting platen system 10, 10' in the open position and it can be seen that the relative position between the slide plate 18 and spacer 25 does not change.

Abstract

L'invention concerne une machine de moulage par soufflage pourvue d'une unité de fermeture, laquelle machine présente des demi-moules de soufflage (9, 9), placés sur des plateaux de fermeture (10, 10), et peut être déplacée entre une station à tête d'extrusion et une station de calibrage, pourvue d'au moins un cylindre (1) dont la tige de piston est reliée à un plateau coulissant supportant un ou plusieurs mandrins de soufflage (4) doté(s) d'une bague coupante (5), les bagues coupantes étant pressées contre un plateau de découpage pendant le processus de calibrage et de soufflage. Cette invention se caractérise en ce qu'au moins un plateau coulissant (18) est fixé au plateau de fermeture (18), lequel plateau coulissant constitue, en position fermée des plateaux de fermeture, une fermeture géométrique avec au moins un crochet (26) et un bras en porte-à-faux, supportant ce crochet, par le biais d'au moins une pièce intermédiaire (25).
