Definitions
- the invention relates to a method for producing casting cores or molds for casting molds from a mold base and a binder, and casting cores or molds after the method has been produced.
- Casting cores have the task of forming cavities in the casting or undercut external contours.
- This type of casting cores is produced in a known manner in core boxes by means of core shooting systems, the molding sand provided with binder and optionally with additives being introduced into the cavities of the core box using compressed air.
- Liquid synthetic resins or inorganic binders are generally used as binders.
- the invention relates to all organic and inorganic mold and core production processes, preferably to the urethane cold box process and / or the resol C0 2 process.
- Physical methods for example ultrasound methods, are also conceivable.
- the core production after the urethane cold box takes place in cold core boxes using organic binder systems that are gas-hardened directly in the core box, for example by tertiary amines.
- the molding material mixture e.g. quartz sand, organic binding system, hardener
- the individual components are mixed beforehand in special facilities.
- One advantage of this urethane cold box process is that the cores or molds have high strength.
- Others, e.g. B. so-called resol-CO 2 processes are core manufacturing processes with alkaline condensed phenolic resin as a binder which is gassed with carbon dioxide for curing.
- the molding material is generally based on the molding material quartz sand. This process is characterized by the prevention of "leaf ribs" in the casting process. A disadvantage of this gassing process are lower strengths, which are due to increased erosion and insufficient thermal stability.
- the finished cores can be coated with a size.
- These are refractory substances in powder, liquid or pasty form for the production of a thin coating on the casting cores.
- the sizing has several tasks. Among other things, the size is used for heat insulation, smoothing, preventing metal from sticking to the mold wall, forming ribs and thus ensuring a safe separation of the casting from the mold wall when the mold is emptied.
- the casting cores are removed from the casting.
- the casting cores are removed, for example, by blasting, vibrating, blowing out, tapping or washing out.
- a casting core for casting molds has become known from DE 195 25 307 A1.
- a casting core for casting molds is proposed from a dry substance solidified by means of a binder, which loses its shape due to the action of water.
- DE 195 49 469 A1 describes a casting core for casting molding from molding sand consolidated by means of a water-soluble binder based on polyphosphates, the binder being instant sodium polyphosphate and that a mixing ratio of 3 to 7 parts by weight of binder and 0.5 to 2 parts by weight of water for 100 parts by weight of molding sand.
- DE 199 14 586 A1 discloses a resin-based binder for the production of foundry sands for use in foundries.
- the binder mixture for core sand production consists of a single component (single resin) or a mixture of one or more individual components (resin mixture) with additives.
- the invention has for its object to provide a casting core or a shape of the type mentioned, which have a pore structure while avoiding the aforementioned disadvantages.
- the use of a size should no longer be necessary.
- the disadvantageous formation of leaf ribs in the casting process should be avoided.
- this object is achieved in that a pore-forming substance is added to the molding material and / or the binder.
- Pore-forming substances give off, for example, carbon dioxide when they are decomposed by acid formers or the action of heat, which produces the desired fine-pored structure in the molding material mixture.
- the use of physical methods, e.g. Ultrasound, contribute.
- the pore-forming substance is not limited to the generation of carbon dioxide. Any pore-forming additive is conceivable which creates the desired pores in the casting core or the casting mold, for example nitrogen-generating substances would also be conceivable.
- the presence of the pore structure means that a subsequent size treatment of the casting core is no longer necessary in order to avoid expansion errors.
- substances are used as pore-forming substances that generate carbon dioxide, such as. B. ammonium carbonate, ammonium hydrogen carbonate, sodium carbonate and / or sodium hydrogen carbonate. It has been shown that sodium hydrogen carbonate proves to be particularly suitable.
- An acidifying agent and / or heat is advantageously added to the carbon dioxide-forming substance.
- the carbon dioxide is released in particular by an acidic environment or by supplying energy in the form of heat.
- an acidifying agent for example tartar, is added to the carbon dioxide-forming substance.
- the binder is composed of a phenolic resin and an isocyanate component in a ratio of 1: 1, the two binder components being added to the molding material at the same time or in succession and then mixed.
- the pore-forming substance can also advantageously be added to the core molding material mixture simultaneously or subsequently with the binder.
- the carbon dioxide-forming substance is added together with a component of the binder.
- the main technical advantages are a simplified, less complex casting process compared to the prior art. Because the size treatment is eliminated due to the fine-pored pore structure and the suitable strength of the casting cores.
- a particularly advantageous exemplary embodiment for the composition of the mixture of quartz sand and binder for the production process according to the invention is specified below.
- resin e.g. phenolic resin
- isocyanate 0.6 parts by weight of isocyanate
- pore-forming material e.g. sodium bicarbonate
- the proportions by weight of resin and isocyanate can be between 0.5 and 1, depending on the desired strength of the casting cores.
- resin and isocyanate are mixed in equal amounts, i.e. H. in a 1: 1 ratio.
- the pore-forming substance is usually added in an amount of 0.5 to 1 parts by weight.
- an acid generator for example tartar
- 0.2 to 0.7 parts by weight of an acid generator for example tartar
- an acid generator for example tartar
- the pore-forming substance is added sequentially, in parallel with both binder components or in parallel with one binder component, the acid generator being added if necessary
- the mixing time is 10 to 120 seconds, depending on the desired requirements and mixer type
- the only figure shows the pore-shaped structure of a casting core material, the mean pore size being 100 nm to 500 nm.
