Description
Verfahren und Vorrichtung zum Herstellen von Flaschen und anderen Hohlkörpern im Blasverfahren aus plastifiziertem Material, insbesondere thermoplastischen Kunststoffen Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Herstellen von maschen und anderen Hohlkörpern im Blasverfahren aus plastifiziertem Material, insbesondere thermoplastischen Kunststoffen, wobei die plastifizierte Masse z. B. in Form eines Rohrabschnittes in eine Hohlform eingebracht und dort mittels eines Druckmediums zu einem Hohlkörper aufgeblasen wird. Das Neue gemäß der Erfindung besteht darin, daß an dem Hohlkörper eine oder mehrere senkrecht zur Längsachse der Form verlaufende Erweiterungen mit angeformt werden, die, bevor die plastische Masse ihre Verschweißbarkeit verloren hat, in der geschlossenen Form eine Pressung in axialer Richtung derart erfahren, daß das Material, welches die die Erweiterung begrenzenden Wandteile bildet, zur Formung von Verstärkungsrändern, Abflachungen, Verstärkungsleisten usw. zusammengedrückt wird. Zweckmäßig erfolgt die Pressung des die Erweiterung begrenzenden Materials durch Verschieben von Formteilen. Method and apparatus for making bottles and others Hollow bodies in the blow molding process made of plasticized material, in particular thermoplastic Plastics The invention relates to a method and a device for manufacturing of meshes and other hollow bodies in the blow molding process made of plasticized material, in particular thermoplastics, the plasticized mass z. B. introduced in the form of a pipe section into a hollow mold and there by means of a Pressure medium is inflated to form a hollow body. The novelty according to the invention consists in that on the hollow body one or more perpendicular to the longitudinal axis the shape extending extensions are molded with that before the plastic Mass has lost its weldability, a compression in the closed form experienced in the axial direction in such a way that the material which the extension delimiting wall parts, for the formation of reinforcement edges, flattened areas, Reinforcing strips, etc. is compressed. The pressing is expedient of the expansion-limiting material by moving moldings.
Die nach dem beschriebenen Verfahren hergestellten Hohlkörper weisen z. B. einen seitlich überstehenden, gegebenenfalls winkelförmig oder profiliert ausgebildeten Rand auf. Darüber hinaus können auch oberhalb des Fußrandes des Hohlkörpers, z. B. an der Schulter einer Flasche od. dgl., ein oder mehrere Verstärkungsringe angebracht sein. Die Erfindung gibt auch die Möglichkeit, durch den überstehenden Rand eine Bodenplatte, einen Kragen od. dgl. zu bilden, die bzw. der im Grundriß von dem Querschnitt der Flasche abweicht. The hollow bodies produced by the method described have z. B. a laterally protruding, possibly angular or profiled trained edge on. In addition, above the base of the hollow body, z. B. od on the shoulder of a bottle. Like., One or more reinforcing rings to be appropriate. The invention also gives the opportunity through the protruding Edge of a base plate, a collar or the like. To form the or the in plan differs from the cross-section of the bottle.
Die Hohlform zur Durchführung des vorgeschriebenen Verfahrens ist zweckmäßig in einer oder mehreren untereinander parallel und senkrecht zur Längsachse der Form verlaufenden Ebenen unterteilt, wobei zwischen diesen einzelnen Abschnitten, die gegeneinander beweglich angeordnet sind, innen umlaufende, z.B. nutenförmige Ausnehmungen vorgesehen sind. Zur Anformung eines Bodenrandes oder einer Schulter z. B. an einer Flasche kann die Form mit einem gegenüber den Mantelteilen bewegbaren Bodenstück versehen sein. Besteht die Hohlform aus zwei Hälften, wie das häufig der Fall ist, dann ist zweckmäßig jedem der beiden Mantelteile ein Bodenstück zugeordnet, das jeweils gegenüber dem zugehörenden Mantelteil bewegbar ist. Jedes dieser Bodenstücke kann durch einen oder mehrere in Bohrungen der zugehörenden Mantelteile geführte Zugbolzen betätigbar sein. Als besonders vorteilhaft hat es sich herausgestellt, die Bewegung der Bodenstücke in Richtung auf die Mantelteile über die Zugbolzen, die Rückbewegung der Bodenteile dagegen durch Federn zu bewirken. Im übrigen können die Bodenteile mit einem Ring, einer Schulter od. dgl. in eine entsprechende Nut oder Randausnehmung der Mantelformteile eingreifen und darin geführt sein. The hollow mold for carrying out the prescribed procedure is expediently in one or more mutually parallel and perpendicular to the longitudinal axis the shape is divided into planes, with between these individual sections, which are arranged to be movable relative to one another, internally circumferential, e.g. groove-shaped Recesses are provided. For molding a base edge or a shoulder z. B. on a bottle, the mold with a relative to the shell parts can be moved Be provided bottom piece. The hollow form consists of two halves, as is often the case is the case, then each of the two shell parts is expediently assigned a base piece, each of which is movable with respect to the associated shell part. Each of these pieces of ground can be guided through one or more bores in the associated shell parts Draw studs can be actuated. It has been found to be particularly advantageous the movement of the base pieces in the direction of the shell parts via the tension bolts, to bring about the return movement of the bottom parts by means of springs. By the way, you can the bottom parts with a ring, a shoulder or the like in a corresponding groove or engage the edge recess of the shell moldings and be guided therein.
Durch eine besondere Ausgestaltung der Blasform kann praktisch jede in Frage kommende Ausbildung des Randes erreicht werden. Es ist auch ohne weiteres möglich, z.B. eine Flasche mit zylindrischem Körper mit einem quadratischen, überstehenden Rand zu versehen. Thanks to a special design of the blow mold, practically everyone can eligible formation of the edge can be achieved. It is also straightforward possible, e.g. a bottle with a cylindrical body with a square protruding Edge to be provided.
Es ist bereits eine Vorrichtung zur Herstellung von Körpern aus thermoplastischem Kunststoff, insbesondere Flaschen, vorgeschlagen worden, bei der der Boden der Blasform kolbenförmig ausgebildet und in axialer Richtung über die gesamte Höhe der Form bewegbar ist. Bei dieser bekannten Ausführung erfolgt die Bewegung der Bodenteile jedoch während des Einführens des Kunststoffes in die Form und im Verlauf des Blasvorganges. Nach Beendigung dieses Vorganges erfolgt keine Einwirkung der Bodenteile auf den Behälter mehr. Demzufolge kann an einer in einer derartigen Vorrichtung hergestellten Flasche auch kein Boden- oder sonstiger Verstärkungsrand hergestellt werden. It is already an apparatus for making bodies from thermoplastic Plastic, especially bottles, has been proposed to hold the bottom of the blow mold piston-shaped and in the axial direction over the entire height of the mold is movable. In this known embodiment, the movement of the base parts takes place however, during the introduction of the plastic into the mold and in the course of the blowing process. After completion of this process, there is no effect of the floor parts on the Container more. As a result, can be produced in such a device Bottle, no bottom or other reinforcing edge can be made.
Es sind weiterhin ein Verfahren und eine Vorrichtung zum Herstellen von Flaschen aus thermoplastischem Kunststoff bekannt, bei welchen die Bodenteile der Form zunächst dicht unterhalb einer Spritzdüse angeordnet und nach dem Abtrennen des in der Form befindlichen, bereits aufgeblasenen Materials bis zur Auflage auf die Formseitenwände abgesenkt werden. Zweck dieser Absenkbewegung soll sein, Verstärkungszonen in den Bereich des Überganges zwischen Boden- und Seitenwänden des zu fertigenden Hohlkörpers herzustellen. Dies ist jedoch nicht möglich. Bei der Abwärtsbewegung der Bodenteile der bekannten Form- wird das an diesen Teilen anliegende thermoplastische Material, welches den Boden der zu fertigenden Flasche bilden soll, eine wellenartige oder sonstige unregelmäßige Form annehmen. There is also a method and an apparatus for manufacturing known from bottles made of thermoplastic material, in which the bottom parts the mold initially arranged just below a spray nozzle and after separation of the already inflated material in the mold up to the support the mold side walls lowered will. Purpose of this lowering movement should be, reinforcement zones in the area of the transition between the bottom and side walls of the hollow body to be manufactured. However, this is not possible. at the downward movement of the bottom parts of the known form - this is what happens to these parts adjacent thermoplastic material, which is the bottom of the bottle to be manufactured should form, assume a wave-like or other irregular shape.
Es ist sogar ohne weiteres möglich, daß das Material, da die Form zu Beginn der Abwärtsbewegung der Bodenteile oben nicht verschlossen ist, seitlich über die Formwandung hinausquillt. Darüber hinaus entsteht auch ein abgerundeter Übergang von den Seitenwänden in den Boden der Flasche, wodurch deren Standfestigkeit zwangläufig sehr schlecht sein muß.It is even easily possible that the material, as the shape at the beginning of the downward movement of the bottom parts is not closed at the top, laterally swells beyond the wall of the mold. In addition, a rounded one is also created Transition from the side walls to the bottom of the bottle, which makes it stable must inevitably be very bad.
Mit keinem der bekannten Verfahren oder Vorrichtungen lassen sich die Vorteile erreichen, die sich bei Anwendung der Erfindung ergeben. Die Vorteile sind unter anderem darin zu sehen, daß durch das Anbringen eines Verstärkungsrandes am Boden z. 3. die Standfestigkeit des Behälters erheblich vergrößert wird. Außerdem können Zonen geringerer Wandstärke, z.B. am Übergang von dem eigentlichen Flaschenkörper in den Boden oder in die Schulter, vermieden werden, indem an diesen Stellen Ränder angepreßt werden. Schließlich ist auch nicht zu übersehen, daß die Möglichkeiten der Gestaltung einer Flasche im Hinblick auf ihre ästhetische Wirkung durch die Anwendung des Vorschlages gemäß der Erfindung erheblich erweitert werden. With none of the known methods or devices can achieve the advantages that result from using the invention. The advantages can be seen, among other things, in the fact that by attaching a reinforcing edge on the ground z. 3. The stability of the container is considerably increased. aside from that zones of smaller wall thickness can be used, e.g. at the transition from the actual bottle body in the floor or in the shoulder, avoid adding edges in these places be pressed. Finally, it cannot be overlooked that the possibilities the design of a bottle with regard to its aesthetic effect through the Application of the proposal according to the invention can be expanded considerably.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigt Fig. 1 einen Längsschnitt durch eine Blasform, wobei das linke den Boden des Werkstückes begrenzende Formteil in seiner Ausgangsstellung, das rechte Teil dagegen in Preßstellung dargestellt ist, Fig. 2 einen Ausschnitt aus einer Blasform mit einer anderen Ausbildung der Führung für die Bodenteile, Fig. 3 einen Behälter mit seitlich überstehendem verstärktem Bodenrand, teilweise im Schnitt, Fig. 4 eine Flasche mit verstärktem Bodenrand und verstärkter Schulter. An exemplary embodiment of the invention is shown in the drawing. It shows Fig. 1 a longitudinal section through a blow mold, the left the bottom the part delimiting the workpiece in its starting position, the right part on the other hand, it is shown in the pressed position, FIG. 2 shows a section of a blow mold with a different design of the guide for the bottom parts, Fig. 3 shows a container with laterally projecting reinforced bottom edge, partially in section, FIG. 4 a Bottle with reinforced bottom rim and reinforced shoulder.
Bei dem Ausführungsbeispiel gemäß Fig. 1 der Zeichnung besteht die Hohlform, in welcher der Behälter hergestellt wird, aus zwei Formhälften mit den beiden Mantelteilen 10 und 11, die horizontal gegeneinander bewegbar sind. An ihrem oberen Ende ist die Form durch die den Boden begrenzenden Teile 12 und 13 verschlossen, die an ihren gegeneinander gerichteten Seiten mit Schneidkanten 14 versehen sind. Die beiden Formteile 12 und 13 sind in vertikaler Richtung, also in Richtung der Längsachse der Form, mittels Zugbolzen 15 und 16 an den Seitenteilen 10 und 11 bewegbar angebracht. Die Zugbolzen 15 und 16 sind in entsprechenden Bohrungen der Seitenteile geführt. Zur genauen Führung der Bodenteile 11 und 12 sind weiterhin an diesen angebrachte und nach unten gerichtete ringförmige Fortsätze 17, 18 vorgesehen, die in Ausnehmungen 19, 20 der Seitenteile 10 und 11 eingreifen. Die Betätigung der Bolzen erfolgt durch Hebel 21 oder Exzenterscheiben 22. Sie kann auch durch andere Mittel, z. 3. hydraulisch oder pneumatisch, geschehen. In the embodiment according to FIG. 1 of the drawing, there is the Hollow mold in which the container is made from two mold halves with the two shell parts 10 and 11, which can be moved horizontally against one another. On theirs the upper end of the mold is closed by the parts 12 and 13 delimiting the bottom, which are provided with cutting edges 14 on their mutually facing sides. The two mold parts 12 and 13 are in the vertical direction, that is, in the direction of the Longitudinal axis of the mold, movable by means of tie bolts 15 and 16 on the side parts 10 and 11 appropriate. The tension bolts 15 and 16 are in corresponding holes in the side parts guided. For precise guidance of the base parts 11 and 12 are still attached to these and downwardly directed annular projections 17, 18 are provided which are in recesses 19, 20 of the side parts 10 and 11 engage. The bolts are actuated by Lever 21 or eccentric disks 22. It can also be used by other means, e.g. 3. hydraulic or pneumatically.
Die Herstellung der Hohlkörper erfolgt in der Weise, daß zunächst ein Zwischenerzeugnis, z. 3. ein Schlauch, in plastischem Zustand in die geöffnete Form über eine in diese hineinragende Blasdüse 23 geführt wird, worauf sich die Form schließt. Die geschlossene Form ist in Fig. 1 der Zeichnung dargestellt. Während des Schließvorganges wird durch die Schneidkanten 14 der Bodenteile 12 und 13 das obere Ende des in der Form befindlichen Schlauchabschnittes verschlossen. Der Blasdorn 23 und die sich um den Blasdorn legenden Formteile kalibrieren den Hals des herzustellenden Hohlkörpers. The production of the hollow body takes place in such a way that initially an intermediate product, e.g. 3. a tube, in a plastic state, into the opened one Form is passed through a blow nozzle 23 protruding into this, whereupon the Form closes. The closed shape is shown in Fig. 1 of the drawing. While of the closing process is through the cutting edges 14 of the bottom parts 12 and 13 closed upper end of the tube section located in the mold. The blow pin 23 and the molded parts around the blow pin calibrate the neck of the to be manufactured Hollow body.
Nach dem Schließen der Form wird durch die Blasdüse 23 ein Druckmittel, z. B. Preßluft, in das in der Form befindliche Zwischenerzeugnis eingeführt, so daß sich das Zwischenerzeugnis an die Wandung der Form anlegt. Nunmehr werden die Bodenteile 12 und 13 über die Zugbolzen 15 und 16 entgegen der Kraft der Federn 27 und 28 in die im rechten Teil der Fig. 1 dargestellte Lage gezogen. Dadurch wird die Wandung 26 des zu fertigenden Behälters, die -wie aus dem linken Teil der Fig. 1 der Zeichnung zu erkennen ist - auch an den Begrenzungsflächen der von den stirnseitigen Flächen 32 und 33 der Formwandteile 10 und 11 und den beweglich angeordneten Bodenteilen 12 und 13 begrenzten Erweiterungen anliegt, gepreßt, so daß aus der im Profil etwa U-förmigen Erweiterung 34 des Behälters (Fig. 1 der Zeichnung, linker Teil) der massive, umlaufende Rand 35 entsteht (Fig. 1, rechter Teil). Die Stärke des Randes 35 hängt dabei, abgesehen von der ursprünglichen Dicke der Wandung 26, von dem Ausmaß der Pressung ab, welche das die U-förmige Erweiterung34 bildende Material erfährt. Der Druck kann so bemessen sein, daß der Rand etwa die doppelte Stärke der Wandung 26 aufweist. Wichtig ist, daß die Stauchung vor dem völligen Hartwerden des das Werkstück bildenden Materials erfolgt. Gegebenenfalls kann die Kühlung und Verfestigung noch durch ein in Kanälen25 umlaufendes Kühlmittel beschleunigt werden. Nach der durch die Bodenteile 12 und 13 bewirkten Pressung werden die Zugbolzen 15 und 16 von den Federn 27 und 28 in ihre in Fig. 1 links dargestellte Ausgangslage zurückgedrückt, sobald der Hebel 21 oder die Exzenterscheiben 22 entsprechend gesteuert werden. Die Form kann jetzt geöffnet und das fertige Werkstück ausgeworfen werden. After the mold has been closed, a pressure medium, z. B. compressed air, introduced into the intermediate product in the mold, so that the intermediate product rests against the wall of the mold. Now the Base parts 12 and 13 over the tension bolts 15 and 16 against the force of the springs 27 and 28 are drawn into the position shown in the right part of FIG. This will the wall 26 of the container to be manufactured, which -as from the left part of Fig. 1 of the drawing can be seen - also on the boundary surfaces of the end faces Areas 32 and 33 of the mold wall parts 10 and 11 and the movably arranged base parts 12 and 13 limited extensions is applied, pressed so that from the profile about U-shaped extension 34 of the container (Fig. 1 of the drawing, left part) of the massive, circumferential edge 35 is created (Fig. 1, right part). The strength of the edge 35 depends, apart from the original thickness of the wall 26, on the extent the pressure which the material forming the U-shaped enlargement34 experiences. The pressure can be such that the edge is about twice the thickness of the wall 26 has. It is important that the compression takes place before the das Workpiece forming material takes place. Optionally, the cooling and solidification can still be accelerated by a coolant circulating in channels25. After The compression caused by the base parts 12 and 13 become the tie bolts 15 and 16 pushed back by the springs 27 and 28 into their starting position shown on the left in FIG. 1, as soon as the lever 21 or the eccentric disks 22 are controlled accordingly. The mold can now be opened and the finished workpiece ejected.
Gemäß Fig.2 der Zeichnung können die Bodenformteile 36, 37 auch mit Schultern 38 versehen sein, die sich gegen eine umlaufende Randausnehmung 39 der Formseitenteile 40 abstützen. According to Figure 2 of the drawing, the bottom moldings 36, 37 can also Shoulders 38 be provided against a circumferential edge recess 39 of the Support mold side parts 40.
