Definitions
- the invention relates to a casting device for a piston for an internal combustion engine and to a method for opening and / or closing a casting device according to the preamble of claims 1 and 7, respectively.
- Cooling recesses are used, largely linear and obliquely with respect to the quills procedure. Presentation of the invention
- the invention has for its object, an apparatus and a method for casting a piston for a
- this has at least one largely linearly movable quill to form at least one
- the quill is thus a component which, at its end directed towards the casting cavity, has a substantially cylindrical section which forms a cavity for the finished piston
- At least one slide which can be moved substantially linearly and at an angle to the sleeve, is provided on the piston for forming at least one recess below the ring field.
- the travel of the slide results from the fact that the recesses under the ring field typically extend at an acute angle to the piston axis and thus obliquely to the axis of the quills extending perpendicular to the piston axis.
- the quill is at least indirectly coupled to the slide in such a way that the quill at least partly entrains the slide during the process. This coupling can during
- Opening the casting device for example, be designed such that the quill initially pulled back a bit is, and then a portion of the quill so at least indirectly engages the slider that it is moved obliquely to the quill.
- the quill is coupled to the slide, in particular for the opening movement, in such a way that it "takes along” it as part of a pulling movement.
- this coupling can also be effective when closing in the context of a "pushing" movement.
- the slider expediently has a projection that forms the positive shape of the desired recess and for a particularly simple retraction when opening the mold is in
- Casting also has any form (halves) that are required for casting a complete piston. Further, both the sleeve and the slider are preferably provided in duplicate to form the necessary configurations on both sides of the piston. Finally, the quill can pass through an opening in the slide.
- common casting devices do not have to be rebuilt. Compared to a pivoting movement of casting cores for the formation of recesses under the ring field also results in the advantage that the recesses can be made deeper, and thus a more extensive
- the slider is in at least one guide
- the movement of the slider can be defined very precisely.
- the coupling with the sleeve can be made flexible to a certain extent, so that the guide can be exchangeable and / or changeable, for example, with regard to the angle, without the
- Slider is connected at least indirectly and at least to some extent pivotally.
- the pivoting fork is pivotable through the sleeve, so that the quill "takes along” the slider by means of the pivoting fork.
- the slider is further at least slightly slidably coupled to the pivoting fork.
- At least one pin on the sleeve preferred, which is engageable with a projection and / or a sliding surface on the pivoting fork in engagement.
- the engagement with a projection is currently preferred for take-along when opening, while the interaction with a sliding surface in the context of
- Fig. 1 is a side view of a part of
- FIG. 2 is a first sectional view of that shown in FIG
- Fig. 3 is a second sectional view of that shown in Fig. 1
- Fig. 4 is a first sectional view of that shown in FIG.
- FIG. 2 is a second sectional view of that shown in FIG.
- Fig. 6 is a first sectional view of that shown in Fig. 1
- Fig. 7 is a second sectional view of that shown in FIG.
- Fig. 1 is a portion of the invention
- the sleeve 10 and the slider 12 are coupled by means of a pivoting fork 16, which is pivotable about an axis 24 in a direction C.
- Pin 18 which is engageable when opening with a projection 20 on the pivoting fork 16 and when closing with a sliding surface 22 on the pivoting fork in engagement.
- Fig. 2 which corresponds to the state of Fig. 1, it can also be seen that the quill 10 extends through an opening in the slider 12, and that the slider 12 according to the figures in the upper region of a nose-like projection 26 for forming a Has recess below the ring field of a piston.
- Pivoting movement is enabled, and also a certain linear displacement (according to the figures from right to left) is allowed.
- This mobility is due to the determination of the movement of the slider by the guide (see. Fig. 1) low, since at said degrees of freedom
- the movement of the slider can be defined by the guide, but can be transmitted through the fork on the slider.
- Casting device correspond and both pinoie as well
