Definitions
- the invention relates to a method for producing a cast part model for a first element of a component that can be assembled from several elements by dividing an overall model of the component in the area of at least one parting plane.
- an overall model is first formed, which has the same shape as the body to be cast. Then the overall model is divided into partial cast models, which in turn are then used to produce negative part molds for the casting process.
- the division of the overall model into cast sub-models can be accomplished by various ablation techniques (e.g. machining or laser ablation). All of these methods have in common that a parting line with finite expansion is created. This means that the partial cast models cannot be reassembled seamlessly to form the overall model. This must be taken into account when producing the individual casting molds using the partial casting models.
- ablation techniques e.g. machining or laser ablation. All of these methods have in common that a parting line with finite expansion is created. This means that the partial cast models cannot be reassembled seamlessly to form the overall model. This must be taken into account when producing the individual casting molds using the partial casting models.
- the invention has for its object to provide a method of the type mentioned, can be created by the cast part models that can be used with as little effort as possible to create greeting forms.
- the object is achieved in that in a method of the type mentioned at least one recess is made in the overall model prior to division and at least one reference surface of the partial casting model of the first element lying in the division plane is formed by a boundary surface of the recess and at after which the overall model is divided, leaving out the areas of the reference surfaces, by introducing a continuous recess, between whose interfaces on the overall model side the division plane runs.
- the partial cast models produced by the process according to the invention can be used to produce casting molds with particularly little effort.
- the reference surfaces serve to define the interfaces with which the various molds will later adjoin one another when they are assembled to form the overall mold. This is done, for example, by placing the partial cast model with the reference surfaces on a straight base plate. The surface of the base plate then defines the parting plane with respect to the cast part model.
- the method according to the invention ensures that the reference surfaces protrude further with respect to the parting plane than the other parts of the cast part model or at least do not lag behind them. This creates between the base plate and the cast part model outside the areas of the reference surfaces if necessary, joints that are sealed before the corresponding mold is created.
- the molds created by molding can later be reassembled without any gaps by adjoining each other in the parting planes and that an overall casting mold is created which, in its dimensions, has a negative shape exactly matches the overall model before the parting corresponds.
- the invention can advantageously be designed in such a way that, in the method, at least one reference surface of the respective cast part model is formed on each of two cast part models adjacent to one another before the division of the overall model by introducing at least one recess into the overall model .
- This design of the method according to the invention ensures that all cast part models have the properties mentioned above, so that all cast part models can be treated equally and the elements created by casting can be assembled without joints.
- a further advantageous embodiment of the invention provides that in the method, by introducing several recesses into the overall model, a number of three reference surfaces for each of the cast partial models corresponding to the number of recesses are formed.
- the invention can advantageously be designed in that, in the method, the recesses are designed as slots running essentially parallel to a division plane.
- a further advantageous embodiment of the invention provides that in each case two reference surfaces of casting partial models which are adjacent to one another before the division of the overall model are arranged alongside one another without a gap along a division plane.
- the invention further relates to an overall model for creating cast partial models for elements of a component composed of several elements by dividing the overall model of the component in the region of at least one division plane, which has at least one recess lying in the region of a division plane, through the boundary surface of which a reference surface of a cast partial model lying in the division plane is formed.
- FIG. 1 shows a simple hollow cylinder 1 as a complete model 1 in a side view.
- the hollow cylinder has six slot-shaped recesses 2, 3, of which only two are visible in FIG. 1.
- the hollow cylinder 1 is divided by the parting plane 4 into two half hollow cylinders 5, 6, which form the partial cast models 5, 6.
- the recesses 2, 3 are arranged such that the recess 2 is delimited on one of its sides by a reference surface 7 of the cast part model 6 (half hollow cylinder 6) lying exactly in the division plane 4.
- the recess 3 is delimited on one of its sides by a reference surface 8 of the cast part model 5 (half hollow cylinder 5) lying in the division plane 4.
- the reference surfaces 7, 8 are highlighted in FIG. 1 by a larger line width.
- the hollow cylinder becomes divided by a continuous recess 9, whose overall model-side interfaces are indicated in FIG. 1 by the dashed lines 10, 11.
- the division plane 4 runs between the interfaces 10, 11 on the model side.
- the continuous recess 9 is, for example, in the form of a saw cut, which excludes the regions 24 of the reference surfaces 7, 8.
- the reference surfaces 7, 8, 12, 13, 14, 15 protrude or lie beyond the remaining boundary surfaces 16, 17, 18, 19, 20 of each partial cast model 5 facing the division plane 4 with these at least in one level.
- each cast part model 5, 6 can be placed on a base plate 21, the surface 22 of which corresponds to the parting plane after the reference surfaces 14, 15 of the cast part model 6 have been placed. This is ensured by the fact that the reference surfaces 14, 15 determine the correct position of the cast part model relative to the base plate 21.
- the resulting cavities 23 are filled before the casting of the partial cast model.
