Definitions

  • the invention relates to low-pressure die casting plants according to claim 1, operating method according to claims 19 and 20.
  • Low-pressure die casting plants are for example from the CH 690 356 and the EP-A 0 824 983 known.
  • the molds consisting of two mold halves are firmly clamped in a handling unit, also referred to as a manipulator.
  • a manipulator This in turn is firmly connected to a transport device which moves the manipulator with the mold from one workstation to the next.
  • the manipulator includes an opening and closing mechanism with which the mold can be opened or closed in accordance with the work steps to be performed at the respective workstation, eg core insertion, casting, casting removal, cleaning, attaching a sizing film.
  • the mold is always transported in the closed state. Because of the high weight of the mold, the opening and closing mechanism requires massive guide parts for the mold halves and the corresponding drive elements.
  • the manipulator must also use great forces to hold together in the casting station both mold halves against the pressure of the rising liquid metal, so that no edges on the casting arise.
  • the manipulator therefore has a large dead weight relative to each other for the application of the required closing force and for moving the mold halves. This mass must be of the transport device under appropriate Energy and time are moved.
  • the manipulator is mechanically complex and therefore expensive to manufacture and maintain. A certain amount of time is required to open and close the mold in the individual workstations, thereby increasing the duration of an entire work cycle and possibly cooling the molds below a minimum temperature, which requires additional heating steps.
  • the invention is therefore an object of the invention to provide a low-pressure Kokillengiessstrom in which the mentioned disadvantages are avoided, the manipulators are mechanically simple design and in which the transport between the individual workstations expires quickly and under reduced energy consumption.
  • the at least one casting station and at least one other workstation preferably a Kerneinlegestation, a removal station, a blasting station and a diving and / or Spraying station
  • at least one first handling unit of a first type at least one second handling unit of a second type are present.
  • the first handling unit is adapted to the transport of a closed mold and the second handling unit to the transport of an open mold, ie each handling unit tailored to the purpose to be fulfilled with it.
  • the handling unit of the first type is optimized for the closing function and the transport of the closed mold.
  • the mold is preferably received by a receiving shaft which surrounds the closed mold of at least two sides, preferably approximately accurate fit.
  • a closing mechanism which, for example, comprises at least one closing piston, the mold halves are pressed against one another and the mold is fixed inside the shaft. The mechanical effort to do so is low, since the closing piston must clamp the mold only within the receiving shaft, with a small stroke is sufficient.
  • On means for opening the mold by the first handling unit is omitted. During casting, the mold remains in the first handling unit.
  • the handling unit of the second type is optimized for the transport of the open mold. Time is saved by moving the dies between the workstations that require open-ended processing in the open state.
  • the second handling unit has two holding elements, each serving to hold a Kokillenhdon, wherein the salary Kokillenhworthn spaced apart and preferably are aligned in parallel.
  • the opened mold is transferred to the workstation for further processing, for example to the core insertion station, or remains attached to the handling unit during the corresponding work step, eg during graphitization of the mold.
  • the handling units are largely free of moving parts and rigid, heavy guide elements.
  • the opening or closing movement is, where necessary, realized by a stationary opening and / or closing device directly to the workstations.
  • the casting station is assigned a clamping unit for receiving a mold with coupling elements, which holds the mold halves together during the casting.
  • a gripping and transport system with at least one handling unit is provided which serves to receive the mold by engaging the coupling elements and for transporting the mold between the other workstation and the casting station or other workstations, wherein the mold at the casting station to the clamping unit transferred or taken over by this.
  • the molds are therefore not firmly clamped in a manipulator, but moved as such between and in the individual stations.
  • handling units of the first or second type according to the first variant of the invention can be used.
  • the necessary closing force is expended by the stationary clamping unit, which receives the mold preferably fitting and in a clamping manner. Since the mold, regardless of the mold has uniform external dimensions, eg at least a predetermined thickness, the clamping unit may be made substantially in one piece, in which the mold is used and, if necessary, is clamped under relatively little effort. The clamping unit does not have to be moved.
  • the handling unit By means of the handling unit, the mold is inserted into the clamping unit and removed again from this. During transport itself, no great forces must be used to hold the mold halves together.
  • the handling unit can therefore for example have a very light gripping and driving unit, which only slightly compresses the mold halves in order to keep them closed. As a handling unit, for example, a robot can be used.
  • the handling unit must be less massive overall than in the case of using the usual manipulators, since lower masses must be moved. It is therefore structurally simpler and cheaper.
  • the systems according to the invention can be constructed completely modularly in a common handling unit approaching all stations. If required, additional workstations can be added or modified, which increases the flexibility of the system.
  • the two variants of the invention can also be combined, for example, by transporting the mold in the closed or open state with handling units of the first and second types and transferring them to a stationary clamping unit at the casting station. In this way, the handling unit of the first type can be made even easier.
  • Moldings having a standardized external shape are preferably used in the systems according to the invention.
  • a mold for example, has a basic body having the actual casting mold and associated coupling elements, e.g. in the form of side flanges or plates. These are arranged such that the spatial dimensions of the mold are independent of the size of the base body at least in one spatial direction. This makes it possible to use a plurality of different molds without any design effort and replace as desired.
  • the holding elements or devices of the handling units, the clamping unit and the other opening and closing devices can be equipped with a uniform gripping system, which allows the manipulation of the mold in the desired manner, e.g. Compression during casting, pulling apart and pivoting for cooling, etc.
  • the receiving shaft of the first handling unit therefore preferably has a depth which is adapted to the distance of the coupling elements of the mold halves in the closed state.
  • the handling units are each connected to a drive device and can be moved independently of each other.
  • the handling units along a linear guide rail are movable and adjustable in height.
  • the molds have a coding which indicates the mold type, eg the casting mold. This is read by means of suitable reading units at the individual stations and transmitted via a corresponding signal to a system control, which may be central or local.
  • the Control Panel provides the workstation with the necessary data to control the work process. For example, in the casting station, a predetermined pressure curve, ie the time-dependent pressure curve, is adjusted, which is adapted to the shape of the casting.
  • a predetermined time depending on the mold is cooled.
  • cleaning station for example, cleaning nozzles are moved over the opened mold, depending on the casting mold.
  • the coding is preferably mechanical, for example an arrangement of pins, but can also be realized in other ways, for example by a barcode or a data carrier. Robust mechanical coding can also be reliably read when used under the poorly clean operating conditions prevailing during casting.
  • each workstation is associated with a local control unit that controls the local operations.
  • the relevant process data are preferably input to a central control unit and queried by the local control unit.
  • FIG. 1a, b and FIG. 1c-e Examples of inventive molds are in FIG. 1a, b and FIG. 1c-e shown.
  • the mold 3 consists of two mold halves 3 a, 3 b formed in mirror image relative to one another, which each have lateral coupling elements 4. These have the form of a plate 5, which is connected via webs 34 with the actual casting mold-carrying base body 9.
  • the coupling element 4 here connected to pins 15 and / or recesses 8 mounted therein, the mold 3 can be picked up by the first and second handling unit 1, 10 and attached thereto.
  • the coupling elements 4 for example, a centrally located in the plate 5 slot 16, arranged at the workstations opening and / or closing devices, ejection devices or other holding devices for attack the mold.
  • the coupling elements 4 are designed so that the coupling points for the handling units 1, 10 or other holding devices regardless of the size and shape of the base body 9 in the closed state are always in the same position relative to each other.
  • the basic body can be extended, for example (compare basic body 9 'in FIG. 1a, b ) or have a changed depth (not shown), in the latter case, the webs 34 would be extended accordingly.
  • Fig. 1c-e show a slightly modified mold 3.
  • a coding 39 here by means of an arrangement of short pins, attached, which can be read by a corresponding reading unit, for example by mechanical scanning.
  • FIGS. 1a, b and 2a, b show the two types of handling units 1, 10, which are used in a low-pressure Kokillengiessstrom according to the first variant of the invention.

The necessary for fixing stroke of the lock cylinder 7 is very small with a few millimeters (about 10 - 20 mm). Other moving parts, the first handling unit 1 does not have, so that it can be produced with little design effort.
  • the closing device 6 By the closing device 6, the closed mold 3 is held both within the first handling unit 1 and held together during the casting.
  • the second handling unit 10 is adapted to the transport of the open mold with spaced, parallel mold halves 3a, 3b. It also comprises a U-shaped frame 11, whose side walls 11a, 11b have a relation to the frame 2 of the first handling unit 1 increased distance.
