Abstract

Molding device comprises an allocating station (9), a core insertion region (12), casting stations (21, 22) connected together by transport systems (4, 5, 6, 16, 20, 23), and a molding station (10) for small molds and a further molding station (11) for large molds. Preferred Features: The molding stations are arranged behind each other and/or parallel to each other.

Description

The invention relates to a molding plant for the production of molding boxes bound casting molds with at least one singling station, one Core loading area and a casting station that are connected to each other via transport systems are connected.

The molding plant consists of the individual required, known per se Stations and are connected in the usual way via a transport system.

Such a molding system is in the utility model DE 297 14 635 U1 disclosed.

Depending on the geometry of the workpieces to be cast, molded boxes are available different sizes required. So far it has been required for everyone Mold box size to drive a separate molding system, so that for example at two different mold box sizes a double number of special Stations are necessary. This requires a large amount of space. Double requirement the same devices and larger space requirements are associated with increased costs.

The invention is based on the object, a molding system for molding boxes propose different sizes with which you can take a line.

According to the invention, the object is achieved in that the molding plant has at least two molding stations, one molding station for small and the other are intended for large molded boxes.

The two are preferably in the single-line molding system Forming stations arranged in series one after the other and / or in parallel.  

The molding plant according to the invention can thus have several different ones in one line Mold, pour and cool large mold boxes.

The pallet trolleys required for the transport are advantageously of this type trained that they have a large molding box or two small molding boxes be able to record.

Furthermore, the object is achieved according to the invention by a method which molds small and large mold boxes using a single-line molding machine.

With this arrangement, only the stations that are independent are needed once of the mold box size.

It can be an advantage that small and large molded boxes in any order are impressionable.

Furthermore, the molding of the differently sized mold boxes can be done in this way take place over a certain period of time small and then large Mold boxes are moldable. Of course, this is also the reverse Order possible.

This way of driving has great advantages in cooling. Size workpieces cool longer than small workpieces, so it is time-saving if you large mold boxes first.  

An embodiment of the invention is described in more detail in the drawing. It demonstrate:

Fig. 1 is a formed according to the invention form complex with serially arranged mold stations,

Fig. 2 is a formed according to the invention form complex with parallel arranged mold stations and

Fig. 3 seen the molded boxes on the transport route from above and from the side.

In Fig. 1 a according to the invention shaped mold system 1 is shown in which the molding boxes located on a pallet trolley 7 2, 3 of different size are lifted by the pallet trolley 7 and placed on a conveyor 4 to a roller conveyor 6 for molding. The empty pallet trucks 7 are forwarded on the conveyor path 5 . The mold boxes 2 , 3 and the pallet trolleys 7 are moved in a clocked manner in a known manner by means of cylinder-piston arrangements 8 .

In this exemplary embodiment, the small molded boxes 2 are half as large in size as the large molded boxes 3 . The pallet trolleys 7 are geometrically designed such that two small molded boxes 2 (upper and lower boxes) have space on a pallet trolley 7 . The lower box or the upper box of a large shape are each transported on a pallet truck 7 , see also FIG. 3.

The molding boxes 2 , 3 now located on the roller conveyor 6 are brought into the appropriate position for the impression, as required, in a turning station 13 and / or separating station 9 . The actual molding is now carried out in the molding station 10 for small molding boxes 2 and in the molding station 11 for molding boxes 3 which are twice large in this example. The molding stations 10 , 11 are designed in a manner known per se. In this example we are dealing with forming stations with a turntable, which enables a double impression. The selection of which molding station is to be controlled is of course dependent on the sequence of the molding boxes 2 , 3 to be molded and is likewise carried out in a known manner by barcode recognition or other known means. After molding, another turning station 13 ′ and the core insertion area 12 follow.

An assembly station 14 assembles the lower box and the upper box to the actual shape. The completed molds are then transported via a transport device 16 to the stylized casting stations 21 and 22 . The mold boxes 2 , 3 are conveyed into the cooling area 15 via the conveying device 23 .

A further molding system 1 'is shown in FIG. 2. In this molding system 1 ', the molding station 10 ' for small molding boxes 2 and the molding station 11 'for large molding boxes 3 are arranged in parallel. The large molding boxes 3 are brought from the roller conveyor 6 to the roller conveyor 19 , in which the molding station 11 'is arranged, via the conveyor 17 . The molded mold boxes 3 then return to the roller conveyor 6 via the conveyor device 18 .

As in the molding line 1 are brought into the molding line 1 'in front of the core insertion region 12, the molding trays 2, 3 on the pallet carriage 7, where the empty pallet trolley 7 travel from the conveying path 5 on the transport device 20 back to the roller conveyor 6 to the molded Mold boxes 2 , 3 to take.

Fig. 3 shows the pallet truck 7 with the molding boxes 2 and 3 in the upper region as seen from above, as seen in the lower area of the page.

The advantages associated with the invention are in particular that the arrangement of a second molding station can save a further line. In addition to saving space, this also includes a cost reduction. One can take large and small impressions at the same time. By being able to To be able to mold boxes of different sizes from a line, it is possible to  choose the optimal mold box size for a particular mold, d. H. the Area allocation can be optimized. Depending on the resulting shape sizes, the Number of molded boxes to be adjusted in size, as is well known costly mold boxes can mean a cost saving. Still works the possibility of using suitably large molded boxes saves costs on the cooling times.
