Definitions

  • the invention relates to a molding machine with a stand, with a compression device arranged on the stand and supported thereon, with a lifting device for a molding box, which molding box is fed to the lifting device from a molding box turntable pivotally mounted on the stand about a first vertical axis.
  • So machine arrangements are known (e.g. DE-OS 38 19 118), which are combined to form a molding system, in which at least one molding track and one casting track and several cooling tracks are provided, on which the molding boxes can be transported.
  • the length of the molding and casting track is dimensioned such that the same number of molding boxes can be found on the molding and casting track as on each of the cooling tracks, in order to ensure a continuous workflow even with different molding boxes and a problem-free change of different types of molding boxes to enable.
  • the empty molding boxes are first provided with the respective model provided and then fed to the molding machine, where they are placed on a turntable unit arranged thereon.
  • the molding box on it is placed under a compacting device.
  • a support device acting from below serves as an abutment for the molding box acted upon from above by the compression device.
  • a further turntable unit is then provided on the stand, which can be pivoted about a second vertical axis and which feeds models to the lifting device.
  • the model turntable unit is offset in height from the molding box turntable unit and is located below the molding box turntable unit.
  • model turntable unit in each case that of the molding box turntable unit supplied upper or lower mold box supplies assigned upper box or lower box model.
  • this second turntable unit integrated in the molding machine, the space requirement for an additional station for providing the casting models is eliminated. This also enables accelerated mold production, which also reduces the storage space otherwise required, since the models required for the upper box mold and for the lower box mold do not have to be positioned in the mold boxes beforehand, but remain quasi stationary on the second rotary table unit. Each time the tables of this model rotary table unit are swiveled, the models with the associated molding box are brought into vertical alignment and are brought together by the lifting device provided on the stand.
  • the gripping and lifting device is arranged in the swivel range of the molding box turntable for this purpose.
  • a preferred embodiment of the invention is characterized in that the gripping and lifting device cooperates with a feed path for empty mold boxes and with a transport path for finished molds.
  • An embodiment of the invention provides that the gripping and lifting device is actuated hydraulically.
  • the gripping and lifting device has a carriage which is used for its to-and-fro movement between the feed path and the molding box rotary table or between the molding box rotary table and the transport path.
  • the molding machine equipped with the gripping and lifting device can, due to its extremely small space requirement, also in otherwise unusable, e.g. B. narrow, rooms can be set up, since with the help of the gripping and lifting device an adaptation to spatial conditions is easily possible.
  • the gripping and lifting device is combined with the further turntable unit, which is pivotably mounted about a second vertical axis, according to one of claims 1 to 4.
  • This offers a further possibility of reducing the space requirement, since all the work processes required for the production of molds are thus spatially concentrated on the molding machine according to the invention.
  • a preferred embodiment is characterized in that two gripping and lifting devices are provided, each of which is assigned a carriage for the back and forth movement between the feed path, the molding box turntable and the transport path.
  • the design of the molding machine according to the invention and its control is provided so that the molding box turntable and the model turntable work synchronously, so that there is always a molding box and an associated model in the molding machine at the same time.
  • Fig. 1 is a schematic representation of the side view of a molding machine according to the invention is shown, which consists of a machine frame 1 called a stand with a base frame 2 and a press bridge 3.
  • a lifting table 4 with a hydraulic actuating cylinder is inserted and guided in the base frame 2, which acts on a model rotary table unit 5 located above it from below.
  • the model turntable 5 is pivotable on one Swivel shaft 6 is arranged, which is arranged as a column connection between the base frame 2 and the press bridge 3.
  • the model turntable unit 5 has two models 7 fastened to pivotable support arms, which are provided as a lower case model 7a and as an upper case model 7b.
  • the upper box model 7b pivoted into the stand 1 is located above the lifting table 4.
  • a carrying arm of a molding box turntable unit 10 loaded with a molding box 12, pivoted into the machine frame, and a filling frame 8 and above it a compression device 9 are arranged, which are supported on the press bridge 3.
  • a second swivel shaft 11 is also provided as a column connection of the base frame 2 to the press bridge 3, on which the molding box turntable unit 10 is pivotably mounted.
  • the gripping and lifting device 16, 17 serves to feed the required molding boxes 12 from an empty box section 19 shown in FIG. 2 to the molding box turntable unit 10, in which, after the molding box 12 has been pivoted into the stand 1, the associated model is placed 7b and its filling with molding sand by means of the compression device 9 the required casting mold is produced.
  • the empty box or feed section 19 is located close to the molding machine, as is the prefabricated box or transport section 20 arranged opposite one another at a short distance.
  • the travel paths of the carriages 18 of the gripping and lifting device 16, 17 are also correspondingly short, so that it is entirely sufficient for the desired rapid passage through the molding machine to provide a total of two gripping and lifting devices 16, 17.
  • the gripping and lifting device 16 is loaded with a finished upper box shape 14, while an empty upper box 13 is located in the gripping and lifting device 17 located on the empty box section.
  • the unloading area provided in the prefabricated box section 20 is empty, so that the transport of the finished upper box mold 14 can be carried out there.
  • the empty upper box can be transported to the molding box turntable unit 10.
  • FIG. 3 shows the entire arrangement according to FIG. 2 after the two carriages 18 have been transported with the gripping and lifting devices 16, 17.
  • the finished upper box mold 14 is placed on the finished box section 20 next to a finished lower box mold 15 already located there.
  • the empty top box 13 is taken over by the molding box turntable unit 10.
  • FIG. 4 shows how the finished lower box mold 12 is removed from the molded box turntable 10 and lifted by the gripping and lifting device 16. At the same time, the device 17 lifts an empty lower box 22 from the empty box section. Then the carriage 18 transports the lower box mold 12 into the prefabricated box section 20 and the empty lower box 22 to the molding box turntable 10.
  • the same work processes 1 to 5 as described above then take place, however, with interchanged molding devices and molding boxes.
  • An important feature of the molding machine according to the invention is that the two rotary table units, the molding box rotary table unit 10 and the model rotary table unit 5 work synchronously, so that there is always an empty lower box and a lower box model 7b or an empty upper box and an upper box model 7a are in the machine.
  • the molding machine according to the invention has the advantage that the molding boxes do not change their direction, ie they always leave the machine in the same position as they are inserted.
  • the function of the molding machine according to the invention after swiveling in the required molded parts is as follows.
  • the lifting table 4 first lifts the model device 7 out of the model turntable 5, continues to move up and lifts the molding box 12, 13 out of the molding box turntable 10 and finally the filling frame 8 out of its holder (not shown here). Now the filling with molding sand takes place, which is then compacted by the compacting device 9 acting on the molding box arrangement 12, 13 from above against the lifting device.
  • the lifting table then lowers again and places the filling frame 8, molding boxes 12, 13 and model device 7 in their centers at the intended locations.
  • the particular advantages of the molding machine according to the invention are that the feeding of the molding boxes, such as the models, to the compaction station takes place with the aid of rotary tables, which requires an extremely small amount of space for installing such a molding machine. Since the otherwise usual preparation rooms can be dispensed with, it is possible to set up this molding machine in a very narrow space, the gripping and lifting device connected to the molding machine for supplying and removing the empty molding boxes or the finished molds to the existing premises can be adjusted without any particular difficulty.
