Definitions
- the invention relates to a blow mold for blow molding containers.
- blow molds of this type consist of a closed at one end, generally cylindrical shape, which can be closed at the other end by a multi-part upper part.
- a major disadvantage of the known blow mold is that only containers of uniform size or length can be produced with this blow mold.
- the object of the present invention is to provide a blow mold which can be used for the manufacture of containers of different sizes, in particular of different lengths.
- the blow mold contains an end part which is guided in the mold in a pressure-tight manner and an adjusting device for axially adjusting the end part.
- the blow mold according to the invention thus contains a closing part which is axially adjustable within the mold and whose length can be changed axially by means of the adjusting device.
- the blow mold according to the invention can therefore be used to produce containers of different lengths and thus containers of very different volumes.
- the end part is advantageously provided with a raised edge on the inside of the mold.
- This upstanding edge can be formed concavely.
- the end part preferably forms an outer wall, the diameter of which is essentially the same as the inner diameter of the mold; the raised edge then continues the outer wall and the outer wall tangential to the curvature of the concave raised edge.
- the end part is a continuous transition from the Prom USST ⁇ ei 1 effected in the mold inner wall by the upstanding edge.
- This continuous transition is of particular advantage for the pressure-tight closure of the adjustable shape.
- the continuous transition between the end part and the mold inner wall has the effect that a seamless transition between the bottom part and the remaining part of the container occurs during the blow molding of containers.
- Blow mold provided an actuator with at least one threaded spindle, the mold outer side attacks the final part.
- one end of this threaded spindle is expediently fastened centrally to the outside of the end part and extends through a support of the form.
- these are expediently arranged symmetrically over the end part.
- the adjusting device can furthermore have at least one Stel nut cooperating with the thread of the threaded spindle, which can be adjusted in a manner known per se, for example by hand or by motor, to adjust the end part and thus to adjust the length of the mold .
- the shape is preferably firmly anchored to the carrier, as a result of which relative adjustments between the shape and the end part are reliably prevented even at high internal pressures in the film.
- blow mold according to the invention is shown schematically and partly in section in the illustration and is explained and described in detail below with reference to the reference numerals.
- blow mold is shown in its entirety in the figure and partly in longitudinal section.
- the blow mold shown and described below is designed in the manner of the device for blow molding, which is described in the aforementioned DE-PS 1479631. The following described However, the formation of the blow mold is not tied to this construction, but can also be used in a corresponding manner in other known designs of blow molding devices.
- the blow mold shown in the figure initially consists of a generally cylindrical mold 1, the wall of which has cooling channels
- cooling channels 2 are provided. These cooling channels 2 are connected to coolants in a known and therefore not particularly illustrated manner! connected.
- This frame construction 3 carries the multi-part molded upper part 5, which is only shown schematically in view.
- the parts of the upper molded part 5 can be displaced relative to one another, for example, by hydraulic devices in such a way that the upper side of the mold 1 is closed and a through opening 6 is formed for the blow mandrel, not shown here.
- This design of the device for blow molding is known from the publication mentioned at the outset and is therefore not described further here.
- the mold 1 is arranged on a carrier 7 which, in the exemplary embodiment shown, forms a carrier plate 8 which is supported on rails 10 by means of running wheels 9.
- the carrier plate 8 is firmly connected to the frame structure 3 by an anchoring; only two of several anchors 11 can be seen in the figure, by means of which the cross member 4 or the frame construction 3 and thus the shape 1 is anchored to the carrier plate 8.
- the mold 1 is closed by an adjustable end part 20, which here forms a base part or a base plate of the mold 1.
- the end part 20 is provided with a raised edge 21, and this raised edge 21 is concave with a curvature 22.
- the end part 20 further defines an outer wall 23, the diameter of which is substantially the same as the inner diameter of the mold 1.
- the naval ⁇ projecting edge 21 extends in continuation of the intend ⁇ wall 23 in such a manner that the outer wall 23 substantially tangent to the curvature 22 of the: * • extends raised rim 21st
- Formaußensei ti g engages an actuator 24 on the end part 20.
- this adjusting device consists of a threaded spindle 25 with a thread 26 and is fastened in the middle to the end part 20.
- the threaded spindle 25 extends through an opening (not shown) in the carrier plate 8.
- the adjusting nut 27 can be adjusted using conventional and therefore not particularly illustrated means so that the axial adjustment of the end part 20 within the mold 1 indicated by the arrow 28 can be effected.
- a plurality of threaded spindles can also be arranged symmetrically distributed over the end part 20, thereby preventing the end part 20 from tilting relative to the mold 1 during the 5 adjustment.
- the firm anchoring of the mold 1 on the support plate 8 by the anchors 11 connected to the frame structure 3 ensures that even at high internal pressures in the closed blow mold no relative movement between the mold 1 and the end part 20 can occur.
- the above-described special design of the upstanding edge 21 supports the pressure-tight closure of the mold 1 by the end part 20.
- This formation of the upstanding edge 21 has the further advantage that a seamless transition between the end part 20 and the Inner wall of the mold 1 exists, so that the container is produced practically without a seam between its bottom part and the other parts of the container.
- the purpose of the new development described above is to create a blow mold which makes it possible to use a single blow mold to produce containers of the most varied and also deviating from standard sizes, without having to use different or differently composed blow molds for each content, so that not only is a considerable technical simplification achieved, but also very considerable investment costs are saved.
