Definitions
- the present invention primarily relates to a closed one Feeder insert, hereafter also called feeder for use in Pouring of metals in molds, with the features according to the preamble of claim 1, so as known from US-A-5,462,106.
- Such feeder inserts are used in the manufacture of a casting mold integrated into these and form a space surrounded by molding material, the has a passage (passage) to the mold cavity and during casting is filled by the casting flow with liquid metal, which during the Freezing process flow back to the casting and the volume deficit at to compensate for the solidification of the casting.
- so-called voids which are shrinkage cavities, which are caused by the Metal volume contraction during the solidification process arise
- the module (volume to surface ratio) of the feeder must be larger than that of the casting.
- the walls of the feeder become common from an exothermic material, such as an aluminothermic Mixture, formed.
- an exothermic material such as an aluminothermic Mixture
- the molding material usually molding sand, in individual cases also other granular materials
- the molding material is then compacted and the feeder thereby more or less firmly from the compacted Molded material included.
- Spring pins are as well as fixed (rigid) mandrels intended to keep a feeder insert in a predetermined position.
- she usually comprise (a) a tubular element for attachment to a model plate, (b) one disposed in the tubular member Spring and (c) a spring resting on the spring, longitudinally within the tubular element telescopically displaceable spike tip element.
- a spring mandrel is usually on the model plate (model surface) attached, and then a feeder insert is placed on it, whose lower surface is in the starting arrangement before filling the Formstoffs located at a predetermined distance from the model surface.
- the separation of the so-called residual feeder i.e. the casting remaining in the feeder insert, solidified metal
- the breaking point i. the mental Interface between casting and feeder, but in a considerable Distance from the casting, somewhere in the range of often several centimeters wide sand gap between casting and feeder insert.
- refractive cores also as constricting, knock-down or collar cores
- the cleaning effort is therefore usually quite high.
- Spring pins are also quite expensive and susceptible to wear.
- the footprint of the specified feeder should be included preferably be dimensioned small without relevant stability disadvantages can.
- the feeder insert should also be put together can be used with a breaker core, the separation of the residual feeder facilitated by the casting.
- a breaker core is doing in Frame of the present text as part of the feeder insert understood and not as a separate component.
- the task is solved by specifying a closed Feeder insert of the type mentioned with the further features according to characterizing Part of claim 1.
- the displaceability of the first and second form element into one another causes the during a conventional compression process in the feeder longitudinal direction acting on the feeder insert according to the invention high Compression pressures (compression forces) do not lead to its destruction, but only tolerated by the compressibility of the surrounding molding material (molding sand) limited insertion of the one element element in the other one.
- the footprint of the feeder insert can small and the Suiterwandung be comparatively thin.
- the form elements should be out of their original configuration, i. out the relative arrangement, which is for the mold elements before wrapping the Feeder insert is provided with molding material, at least 5 mm, preferably can be pushed together by 10 mm.
- the feeder insert can meet the requirements of the individual case corresponding, for example, in the manner of a compact or ball feeder designed or with a nearly cylindrical top in the upper riser be provided.
- spring mandrels with the feeder inserts according to the invention is therefore not excluded, but usually can but on it be waived.
- a preferred feeder insert according to the invention is therefore in particular, for use with a centering mandrel can be designed as a self-centering feeder.
- a self-centering Feiser has one or more wall sections that towards the top in operation (opposite the feeder passage) Rejuvenate the end wall of the feeder so that a spike tip when positioning the feeder insert along these sections into theirs Target position is guided.
- a centering provided for receiving the mandrel tip cf. our DE utility model 93 03 392.
- a self-centering feeder according to the invention especially suitable for use on fast molding equipment.
- First and second form element of a feeder insert according to the invention can be glued together after production or otherwise get connected.
- the form elements can also be used as separate parts stored and combined (stacked) as needed.
- Identical first (or second) form elements can be with style (e.g., in size) different second (or first) features be combined to respective feeder inserts according to the invention.
- the holding elements are preferably an integral part of respective formula elements, and they can be used in the manufacture of each Moldings without additional step to be molded to this. It can in particular with them stand or clamping projections, circumferential Stand rings, engageable with complementary recesses pins or the like. It is important in each case that the holding elements are designed so that they in the foundry, if first and second Form element still present approximately in their initial arrangement, the molding material but already filled in the molding box, by the subsequent Molding material compaction process of its associated form element can be separated or at least so far deformed that first and telescoping second mold element.
- the retaining elements are therefore preferably only over small connecting surfaces with their associated Form element connected.
- retaining elements As an alternative to the use of retaining elements is the use of a Spring mandrel.
- a Spring mandrel Such a can namely a second, in operation upper Shaping element in the intended starting position relative to the model surface and hold the first mold element without the invention
- Feeder insert itself includes holding elements. But spring thorns like mentioned in the beginning are quite expensive and susceptible to wear, is their use limited to exceptional cases.
- this is closer to the passage of the feeder sleeve or this forming first mold element designed so that it (optionally after separation or deformation of holding elements) in the second mold element can be inserted.
- the outside dimensions of the first, in Operation lower, the casting closer molding element are therefore preferred smaller than the inner dimensions of the associated second, in operation upper Form element.
- This embodiment is compared with the reverse one (Also inventive) embodiment in which the upper in operation Form element in the lower mold element can be inserted, advantageous because it ensures that during the filling process no disturbing quantities Mold material penetrate into the first mold element.
- the first, im Operation lower mold element is designed so that it (telescopically) in the second mold element can be inserted, wherein the outer wall of the first element form fit into the inner wall of the second element element intervenes.
- the gap width between the outer wall of the first Formulas and the inner wall of the second formula element is in the intended output arrangement of the mold elements, if necessary is characterized by the position of the holding elements, preferably maximum 3 mm, advantageously not more than 1.5 mm.
- the mold elements should be made of their intended, if necessary by the holding elements defined output arrangement out in the feeder longitudinal direction by at least 5 mm, preferably by at least 10 mm into each other let it before, due to the further nesting forces occurring between the form elements to break or Breaking of the first or second formula element comes.
- the first and / or the second form element includes one or more guide elements that are arranged a tilting or tilting of the two form elements relative to each other at least substantially prevent, if this (from the starting arrangement out) along the feeder longitudinal axis into each other become.
- These guide elements preferably have the shape in Feeder longitudinally extending thin strips or beads, and she are advantageously located on the outer wall of that element, which can be inserted into the partner mold element; in In a large number of cases they are on the outside of the first one Formula elements arranged.
- a breaking edge if necessary Part of a breaker core, which is then in operation directly on the model plate can be put on.
- This integration of a breaking edge (of a refractive core) ensures a significant reduction in the foundry business Putzaufwands in comparison with the known feeder inserts, the Use with spring thorns are provided and therefore no breaking edge (no breaker core) own.
- the footprint of the feeder according to the invention especially when using a crushing edge (a refractive core) very kept small.
- the feeder insert according to the invention or the associated form elements may be partially or completely made of insulating or exothermic molding compounds be prepared. If a breaker core is integrated into the first shaping element, so this is typically not exothermic, the associated second Form element will then often be exothermic.
- the feeder inserts according to the invention comprise two or more Shaped elements that are combined according to demand when stored separately can.
- the invention therefore also relates to a kit for manufacturing a feeder insert according to the invention, comprising a first mold element and a second mold member which can be arranged to be along a feeder longitudinal axis are slidable.
- preferred Embodiments of belonging to the kit form elements are the above to remove the feeder insert according to the invention.
- the molding machine comprises in the usual way a model plate (i.e., a patterning machine for molding machines, usually consisting of a flat plate with cast-in or mechanically fastened models), and the first mold member is preferably arranged to project the compression process in direct contact with the model plate (the Model surface) stands. This is especially true when in the first Form element is integrated a breaker core.
- a model plate i.e., a patterning machine for molding machines, usually consisting of a flat plate with cast-in or mechanically fastened models
- the first mold member is preferably arranged to project the compression process in direct contact with the model plate (the Model surface) stands. This is especially true when in the first Form element is integrated a breaker core.
- Feeder insert 2 comprises a first (lower) mold element 4 and a second (Upper) mold element 6, wherein both mold elements are substantially rotationally symmetrical are formed.
- the longitudinal axis of rotation of the feeder insert 2 is indicated by a dashed line Line 20 marked.
- the first mold element 4 is shown separately in Fig. 1b again Longitudinal section and shown in Fig. 1b in plan view. It is off a molding compound (e.g., insulating or exothermic) shaped and relative thin-walled.
- the footprint of the first element element 4, with the this is seated on a model plate 22 is small, the footprint diameter is only about 40 mm, the diameter of the inside of the footprint lying feeder passage only about 20 mm.
- Starting from his Footprint expands the first form element outside to a maximum Diameter of about 77 mm conical, and the thus defined conical Section 34 then merges into an upper section 44 which follows at the top very slightly conical up to a diameter of about 76 mm rejuvenated.
- the holding projections 12 are also assigned a total of four Guide and spacer strips 14 extending from the retaining projections extend in the longitudinal direction of the feeder sleeve 2 upwards and opposite the outer wall of the upper portion 44 of the lower mold element 4 each project by about 2 mm.
- Fig. 1a With its lower edge 26 on the retaining projections 12th of the lower mold element 4 is placed on the second (upper) mold element 6. It is formed from an exothermic molding compound and also very thin-walled educated.
- the outer contour of the upper mold element 6 tapers towards the top slightly towards one on the outside substantially flat upper wall termination 36.
- the inner wall of the upper Formulas 4 runs, starting from the lower edge 26 first parallel to the outer wall of the upper portion 44 of the lower mold element 4 and then goes into a conically upwardly tapering wall section 46 above, along which the top of a centering pin at Positioning of the feeder insert can be performed.
- the conical Wandungsabêt 46 finally opens into a in the feeder axis lying, passing through the termination 36 ZentrierausEnglishung 56 for Picking up a thorn top.
- the two form elements 4, 6 are designed so that the four Guide rails 14 of the lower mold element 4 frictionally engaged on the inner wall of the upper die element 6, if this, as in Fig. 1a shown in the output arrangement on the four retaining projections of the lower element 4 rests. They therefore cause a press fit and prevent an undesired lateral displacement of the two form elements; they also define a uniform width of the gap between the lower (here inner) and the upper (here outer) form element.
- a centering pin 16 is located, which is attached to the model plate 22 and from there (always in the feeder rotational axis 20) through the feeder passage 10 and the feeder cavity through into the Zentrierausappelung 56 inside extends.
- the two form elements 4, 6 of the feeder insert 2 can be telescopically push together when parallel to the axis of rotation 20 a directed onto the pattern plate 22 force (arrow F) on the feeder insert acts, as for example after the filling of molding material Forming is the case (see Fig. 3a-d).
- the force only has to be sufficiently large to the retaining projections 12 from the lower mold element. 4 separate.
- the inner wall of the second (upper, outer) element element approaches when pushed onto the first (lower, inner) form element of the Outside wall continuously and finally passes, after a displacement path of about 15 mm, all around in contact with it. Such a displacement path is enough for many compaction processes.
- the final position of the lower edge 26 of the upper mold element 6 after covering said Displacement path is indicated by a dashed line.
- the Guide rails 14 are when nesting the mold elements 4.6 deformed or severed and / or they cut into the inner wall of the outer (upper) element element 6.
- the centering recess 56 extends through the upper end wall of the feeder sleeve 2 and the tip of the centering mandrel comprises a cylindrical portion which is significantly longer than 15 mm and its diameter to the inner diameter of the ZentrierausEnglishung 56th is adapted. This is why it comes with the telescopic sliding of the upper on the lower mold element not to a handicap; the spike tip occurs rather unimpeded out of the feeder insert.
- the lower edge 26 of the lower mold element 4 projecting wall of the upper die element 6 acts like a during a compression process Stamp surface on the molded material to be compressed between edge 26 and Model plate 22.
- the (also) using a compaction process The processes occurring in the feeder insert 2 are described below with reference to FIG. 3a-d explained in more detail.
- FIG. 2 shows an alternative feeder insert 202 according to the invention shown in longitudinal section.
- the feeder sleeve 202 is also more compact and Thick walled trained as the feeder 2.
- the existing here Centering recess 256 does not pass through the upper end of the riser, but extends in the longitudinal direction of the feeder insert so far that an associated centering mandrel inserted sufficiently far into it can be when the upper mold member 206 telescopically on the lower Form element 204 is moved in the direction of the model plate.
- Figs. 3a-d is a method according to the invention for the arrangement a feeder insert according to the invention in a casting mold schematically shown.
- the following explanations apply to the feeder insert 1a-c as well as for the feeder sleeve of FIG. 2.
- a first mold element 104 is on a centering mandrel 116 mounted, which is mounted on a pattern plate 122.
- the form element 104 is in direct contact with the model plate 122 brought.
- FIG. 3b a second mold element 106 on the first mold element 104 placed so that it is supported by this.
- retaining projections 112 are provided which in their shape and function explained with reference to FIGS. 1a-c retaining projections 12th correspond.
- the retaining projections 112 are from the first Shaped element 104, the second (upper) mold element 106 is telescopically a little way on the first (lower) mold element 104th postponed.
- the displacement path D of the second feature 106 on the fixed in its position first mold element 104 is thereby by the measure the molding material compression predetermined and limited.
