Definitions
- the invention relates to a method for producing molds or cores, in particular for foundry purposes, from a mixture of sand or molding material and a binder, which is in particular water-soluble and / or hygroscopic, wherein the mixture by means of at least one shooting unit from this in a shooting process by at least a scrap opening disposed on a shooting plate is shot into a forming or core tool and then cured, wherein at least between two firing operations the area of the broke opening is moistened and / or kept moist by means of a liquid or water.
- the invention further relates to an apparatus for producing molds or cores, in particular for foundry purposes, from a mixture of sand or molding material and a preferably inorganic binder, which is in particular water-soluble and / or hygroscopic, with at least one shooting unit having a shooting tube and a shooting head, wherein at the shooting head a shooting plate with at least one reject opening and a device for the moistening are provided, in particular for carrying out the aforementioned method.
- Such a method and a comparable device are out DE 103 40 491 B3 known. It is provided for the realization of the method that the moisture is supplied as a finely divided or sprayed or atomized liquid. However, it has been shown that by doing so get much liquid in the area of the reject orifices or outlets and the binder from the mixture of sand and binder leach out or swamp out and / or make in the reject openings or outlets and shortly above it located mixture of sand and binder to moist, so that within the Mold or core tool differently moist mixture areas of sand or molding material and binder may be present, which can lead to irregularities of the mold or the core.
- the moistening liquid or moistening water is ultrasonically atomized to a buoyant aerosol and supplied to the region of the broke opening and / or the shooting unit or the shooting head.
- ultrasound liquid for example water-containing liquid or even water
- a suspended aerosol whose liquid constituents are so small that they pass into atmospheric moisture without condensing and without condensate in the region knock down the reject opening for the sand-binder mixture.
- the size of the fluid particles produced by ultrasound may be on the order of 0.01 millimeters or less.
- a sufficiently high humidity is achieved, which prevents the drying of the sand-binder mixture, for example, between two shots, so that the individual shots can be done safely, without causing unevenly moist areas in the form or in the core.
- the aerosol or the quantity of this aerosol which can be aerated and the size of the volumetric flow provided with the aerosol can be adjusted by changing the pulse packets delivered by the ultrasound transmitter (s) and / or by changing the voltage of the ultrasound transmitter (s). In this way, the amount of aerosol that can be aerated, which wets the area of the reject opening (s), can be adapted to existing conditions such as atmospheric humidity, number of rejected openings and ambient temperature.
- a particularly expedient embodiment of the method according to the invention may consist in that the aerosol can be suspended formed at a distance from the / the reject openings and fed via a line of the / the reject openings.
- the aerosol can be suspended formed at a distance from the / the reject openings and fed via a line of the / the reject openings.
- Another particularly advantageous embodiment of the method according to the invention can be that the sand supply in the shooting tube and / or in the shooting head is moistened with a liquid aerosol.
- the shooting tube and / or the shooting head can therefore also be connected via one or more lines with an ultrasonic atomizer for liquid or water, so that the sand supply and in particular its surface, which could otherwise possibly form a crust, are moistened, but without drenched What can be done in addition to direct humidification of the reject opening or instead as indirect humidification of the reject opening.
- the device defined at the outset is characterized in that it comprises at least one ultrasonic atomizer for water or for a liquid containing in particular water, and that this ultrasonic atomizer is in communication with the reject orifices.
- the invention makes use of the fact or knowledge that with ultrasound donors water or a water-containing liquid can be atomized such that the individual droplets can be less than 20 thousandths of a millimeter or even less than 10 thousandths of a millimeter, so that they in humidity and do not precipitate as a moisture film on parts of the shooting unit and in particular in the area of the reject opening.
- the ultrasonic transmitter (s) and the associated liquid reservoir are spatially separated from the shooting unit and connected to the region of the reject opening (s) via at least one pipe or hose line.
- the floating aerosol formed by an ultrasonic atomizer made of water or of a liquid containing water can be easily transported over several meters through such a conduit to then provide sufficiently humid air at the or the reject openings, which drying of the mixture of sand or mold material and binder prevented in particular in the reject openings, but without too much wet this mixture.
- the liquid reservoir with ultrasound generator can advantageously be arranged at a location of the forming or core shooter or near this machine, where sufficient space is available for it.
- a fan and / or a pressure connection can be arranged in particular above the liquid surface of the liquid reservoir.
- a fan or a compressed gas connection can improve this flow or also allow a greater distance of the ultrasonic transmitter from the reject openings.
- the aerosol can also be conveyed upwards so that the ultrasound transmitter can also be arranged deeper with the liquid reservoir, where as a rule there is sufficient space therefor. It is advantageous in this case that any condensate which may occur can flow back down into the reservoir on the inner walls of the pipe or hose in which the aerosol is transported.
- the liquid reservoir is a closed liquid container and is under pressure by a fan arranged in or on one of its walls or effective there and / or pressure connection. Accordingly, the aerosol generated by an ultrasonic atomizer can be transported to the place of its destination.
- liquid reservoir it is particularly advantageous if one or more, for example, two ultrasonic atomizers are provided on the liquid reservoir.
- the surface of the liquid reservoir and the liquid contained therein can be correspondingly large and a corresponding amount of aerosol can be generated, so that correspondingly large shooting units can be kept moist at several places at the same time.
- the shooting head may include a movable guard having a scavenging hood having the aerosol port removable or movable away from the individual shots, and the connecting line from the ultrasonic atomizer and liquid reservoir to the guard may be a telescoping tube or a hose.
- a movable protection device and flushing hood to provide, since it can be connected to the movable line, which can join the movements of the protective device.
- the shooting tube and / or the shooting head of the shooting unit is / are connected via one or more lines to the ultrasonic atomizer and the liquid reservoir.
- the sand supply can thereby be specifically moistened in such a way that only a small or possibly no moisture supply at the exit or shooting opening is no longer necessary, but the moisture is supplied to the region of the reject opening via the sand reservoir.
- direct or indirect delivery of the aerosol to the reject port (s) may be provided, with a combination of both promising the best results.
- FIG. 1 shows in a schematic representation of a longitudinal section through a shooting unit for supplying a mixture of sand or molding material and a binder to a likewise schematically shown in vertical section core tool, wherein on a belonging to the shooting unit protection device with gas flushing hood on the one hand and on a belonging to the shooting unit shooting on the other hand respectively opens a conduit that comes from a liquid container with ultrasonic atomizers and is used to moisten the reject opening and the sand stock.
