  • the present invention relates to a device and a method for curing foundry cores from sand-containing moldings, wherein the core for curing in a core mold via a gas-tight at the core mold gassing plate a gassing a catalyst vapor carrier gas mixture and then a compressed air stream , each with a predetermined pressure and temperature is exposed.
  • Such cold curing processes and equipment are known, such as the so-called cold box process in which two components of a resin system are added to the core sand, which then cure with the sand as soon as an organic catalyst such as an amine, such as an alkylamine or a methyl formate , is added as a catalyst.
  • an organic catalyst such as an amine, such as an alkylamine or a methyl formate
  • the one component could be e.g. a polyester resin, a polyether resin or any synthetic resin of liquid consistency with reactive hydroxyl groups; the second component is definitely an organic isocyanate.
  • the two components are thoroughly mixed with the foundry sand and then deformed. In order to catalyze the reaction now and to make the handling and use of particular amines reliable, various efforts have been made so far.
  • the known methods and devices have a common drawback by the curing process takes a considerable amount of time.
  • the formation of the core-sand mixture in the mold on a core-shooting machine often takes only a fraction of a second, whereas the subsequent gassing to harden the core has to be done over several seconds, which of course fumigation to an enormous cost bearer power.
  • metering pumps are switched between the catalyst source and the mixing point of the carrier gas and catalyst to better meter the catalyst, but this can only lead to an unsatisfactory result, since the pressure conditions in the catalyst flow in each dosing initially absolutely indifferent.
  • valve means comprise a multi-way valve in the flow line of the storage container, which is temporarily switched to a return line to the feed tank for pressure equalization in the flow system.
  • EP 1 375 031 B1 the same applicant a method and a device of the aforementioned type, in which the preheated compressed air is supplied via a switching valve of a heater and mixer and a reheater via a line for further heating for purging.
  • the advantage of this device or this method is that the compressed air for gassing with increasing heating of the catalyst vapor-carrier gas mixture can be heated variably to achieve a so-called contour hardening.
  • a disadvantage of this device is that a precise monitoring of the temperatures is necessary to ensure the safety of To ensure plant.
  • the object of the present invention is now to provide a method for curing foundry cores from sand-containing moldings, as well as to provide a corresponding device by which a constant reduction of emissions at the workplace is ensured by reduced catalyst consumption at constant speed or cycle time. Furthermore, thereby the disposal costs and the cleaning costs for the device are reduced and thus a much lower environmental impact can be achieved. In addition, the device should be inexpensive.
  • the invention relates to a device for curing foundry cores from a sand-containing molding material, wherein the device is adapted to the core for its curing in a core mold a catalyst vapor-carrier gas mixture and subsequently a compressed air flow, each with a predetermined pressure and predetermined Temperature, suspend.
  • this device is characterized in that the device does not have a preheater, which heats the compressed air before it is fed to the heating and mixing stage or the heating source, so that the organic catalyst and the compressed air are heated together in the heating and mixing stage are arranged, and that a first check valve in the second line, which connects the compressed air source to the heater and mixer, is arranged, which is closed at the beginning of the purge, and that a second check valve in the fourth line, which the compressed air source via the heat source is connected to the gassing plate, is arranged, which is open at the beginning of the rinse.
  • the device has two gas sources, of which the first is connected to the heater and mixer, and the second is connected to the heat source. Furthermore, it is advantageous if the heat source is switched on a temperature control. Further, it is advantageous if, prior to the supply of the catalyst in liquid form in the heater and mixing stage, the supply of the liquid catalyst container or the reservoir with a flow meter via a changeover valve temporarily switched to a return line to the reservoir for pressure equalization in the flow system can.
  • the present invention relates to a method for curing foundry cores, which is inventively characterized in that the guided for a timed fumigation through the heating and mixing stage compressed air is heated only in the heating and mixing stage together with the organic catalyst, and the compressed air used for the timed purging is conducted and heated by means of a heating source in a separate line.
  • a preferred embodiment of the method according to the invention is that before the supply of the catalyst in liquid form in the heater and mixing stage in the flow pressure equalization is prepared. Further, it is advantageous if the catalyst vapor-carrier gas mixture is heat-accompanied on its way to the core-forming tool.
  • the device comprises first a gas-tight coupled to the core mold gassing plate or hood 20 with an upstream heater and mixing stage 12 for transferring the liquid organic catalyst, which is preferably an amine, in its gaseous state and for generating one of the gassing of the core serving catalyst vapor-carrier gas mixture, as will be explained in more detail below.
  • the liquid organic catalyst which is preferably an amine
  • the organic catalyst in liquid form from a storage container or a liquid catalyst container 7 is metered via metering means 8 and 11, a metering unit 9, a flow meter 10 or the like via a line L1 into the heaters for timed gasification - And mixing stage 12, where it is converted into its gaseous state.
