Definitions
- the invention relates to a molding material for the production of moldings for casting molds for casting molten metals, in particular light metal melts, such as cast aluminum melts. Moreover, the invention relates to moldings produced from such a molding material. Finally, the invention provides a method with which molded parts can be produced from molded materials according to the invention.
- quartz sand is usually used as a raw material of molded materials from which moldings, such as casting cores, are produced for casting molds. This sand is placed in advance in a mixer and mixed with a binder. The molding material obtained by this mixture is then injected into the mold cavity defining the shape of the molding to be produced. Subsequently, the solidification of the molding takes place in the mold. If an organic binder, for example synthetic resin-based binder, is used, a chemical reaction in the molding material injected into the molding tool is brought about.
- an organic binder for example synthetic resin-based binder
- an inorganic for example, water-glass-based binder
- heat is usually added to the molding material contained in the mold in order to bring about the solidification of the molded part to be produced by evaporation of the water contained in the molding material.
- quartz sand as a raw material for the production of moldings has proven itself in many ways, especially in the field of casting of light metal materials.
- quartz sand can be obtained inexpensively and is characterized by a simple processability and a good quality in the image of the mold elements of each mold part to be produced.
- JP-A-06 063683 discloses the use of Chromitsend, so a quartz-free sand, as a base form stoFP for moldings of Gie ⁇ formen.
- the object of the invention was to provide a molding material, which allows the cost-effective production of mold parts, in particular casting cores.
- low cost manufacturable molded parts and a method should be specified, which makes it possible to produce such moldings.
- this object is achieved in that such a molding material from a base material produced on the basis of olivine sand and a mixed with the molding base, based on Water glass produced inorganic binder is made.
- Olivine sand is a widespread mineral that is available in large quantities at low cost.
- molding materials which are produced according to the invention on the basis of a wholly or at least predominantly quartz-free olivine sands base material, even when properly bonded with a water glass binder from the finished casting.
- the remaining sand retention on the casting is reduced to a minimum. In this way, even when using Moldings made of novel moldings containing a water glass binder can be guaranteed to give sanding adherence-free castings.
- the molding material produced on the basis of quartz-free olivine sand according to the invention creates the prerequisite for cost-effective production of castings.
- the outlay for sand removal is reduced compared with that which is obtained in the cleaning of cast parts which have been cast using molded parts produced from conventional, quartz-containing molding materials.
- the molding material used according to the invention can consist entirely of quartz-free olivine sand.
- One of the requirements of practice particularly well fulfilling molding composition is characterized in that it contains 1.5 to 3.0 wt .-% water glass.
- To improve the sand life of the molding material of the invention may contain 0.3 to 0.5 wt .-% sodium hydroxide solution.
- a molded part according to the invention for casting molds which is in particular a casting core, is produced from a molding material according to the invention.
- the advantageous effects achieved by using a molding material system based on the mixture of quartz-free sands and an inorganic water glass binder in the casting of light metal melts are independent of the process by which the respective molded parts, in particular casting cores, have been produced.
- moldings which are produced by mixing quartz-free sands according to the invention, in particular olivine sand precursors, with an inorganic binder can reliably produce molded parts which not only have a particularly high strength and image fidelity, but moreover have the property of to disintegrate without adhesion during the production of the castings. Decay promoting additives in the binder system are no longer required. Therefore, in the application of the invention, environmental stresses and hazards to the operator are avoided by escaping gases whose formation and unwanted spread can be minimized in conventional manufacturing only with great technical effort.
- the temperature of the molding box in the first stage of solidification should be 150 ° C to 200 ° C.
- the complete curing of the molding then adjusts safely when the exposure time of the microwave heating in the second phase of solidification is 2 - 5 minutes.
- the respective exposure time can be adjusted taking into account the complexity of the shaping so that at the end of the microwave treatment sufficient for the casting process final strength and dryness of the molding is guaranteed.
- a molding material has subsequently been produced by mixing the molding material with a waterglass binder.
- a proportion of sodium hydroxide solution has been added to the molding base to improve its durability.
- the mold base material thus composed contained 2.5% by weight of waterglass binder, 0.3% by weight of sodium hydroxide solution and the remainder the molding base material of the above-described composition.
- This molding material has been placed in the cavity of a preheated molding box which images the finished casting core. Due to the excellent flowability of the molding material while difficult-shaped, small-part mold elements of the cavity have been filled safely. This secure mold filling has also been supported by the fact that the mold box has already been subjected to negative pressure during the filling process. The negative pressure was 0.3 bar.
- the temperature of the mold box was 180 ° C when filling the molding material. At this temperature, after completion of the filling operation in the molding box, the molding material has been held for 30 seconds with still effective negative pressure. At this time formed in the area of the inner walls of the Mold box adjacent areas of the molding material, a solid outer shell. In this way, at the end of the completed in the mold box first stage of solidification, a molding was available, the strength was sufficient to be able to safely transport it in a microwave oven can.
- the molded article In the microwave oven, the molded article has been microwave heated for 3 minutes until it has reached a final strength sufficient for the casting insert.
- the casting core thus produced has then been placed in a casting mold, in which subsequently the melt produced from the aluminum casting alloy has been cast to the cylinder head to be produced.
- the casting core is automatically disintegrated into many small fragments due to the temperature influence of the casting heat and its due to the solidification of the casting mechanical stress, which could be easily removed after complete solidification of the casting.
