Definitions
- the invention relates to a feeder insert for use in a vertically divided mold used in the casting of metals, having an inner cavity as a feeder volume, consisting of an exothermic and / or insulating material feeder body, which in its one when the mold is produced in the mold
- the model body facing the bottom surface of the model has a feed opening for connecting the cavity to the mold cavity of the mold, the feeder body being oriented with its longitudinal axis through the feed opening at an angle to the model oriented vertically, and the volume of the interior cavity relative to one in or is designed asymmetrically parallel to the longitudinal axis imaginary dividing plane.
- a feeder insert with the aforementioned features is known from EP 2489450 AI.
- This feeder insert is already intended for use in a vertically divided mold and set up.
- Such a vertically divided mold is known and results for example from WO 2010/041091 AI.
- the feeder insert in the production of the mold on a vertical model or a corresponding model plate oriented and molded in a quasi-horizontal arrangement in the mold, so that its feed opening is also oriented substantially vertically.
- the feeder insert is offset eccentrically downwards relative to the longitudinal center axis of the feeder body, wherein the volume of the inner cavity above the feeder opening is greater than the volume below the feeder opening.
- the feeder body can also be tilted upwards with its longitudinal axis from the horizontal. This is to ensure that the feed opening is covered during the casting process in each case by the pending in the inner cavity liquid metal.
- the known feeder insert also has a so-called William kernel in the form of a protrusion formed on a wall area enclosing the inner cavity and protruding with its tip into the inner cavity. This William core is in the above the feeder opening located and having the larger volume portion of the inner cavity of the feeder sleeve.
- a feeder arrangement is known in which above a vertically molded in a mold feeder insert in the mold sand introduced to form the mold, a feeder head is formed with a receiving of liquid metal cavity serving. From a side wall of the feeder head projects into the cavity an e- b here vertically oriented William kernel whose facing the feeder insert lower surface at a distance from the feeder insert and runs parallel to it. For a horizontal arrangement and a corresponding design of the feeder assembly in the mold, such a composition is not suitable.
- the invention is therefore based on the object, a feeder insert with the aforementioned-n, generic features in such a way that a faulty orientation of the feeder insert is avoided when molding into a vertically divided mold and at the same time the advantage of a complete feed of the mold cavity is maintained.
- the solution to this problem arises, including advantageous refinements and developments of the invention from the content of the claims, which are adjusted to this description.
- the invention provides that the feeder body with respect to the parting plane has an unequal mass distribution with a center of mass on a side of the dividing plane and at a distance therefrom and the region of the inner cavity of the feeder body situated on the side of the dividing plane opposite the center of mass has a larger volume than the region of the inner cavity located on the side of the graduation plane which faces the center of mass.
- the feeder insert aligns automatically due to the uneven mass distribution during molding. If a feeder insert formed according to the invention is fitted onto a forming mandrel when the casting model is loaded, for example, the feeder insert automatically rotates to a position in which the greater volume fraction of the internal cavity lies above the longitudinal axis of the feeder body extending through the feeder opening. This ensures that the stored volume of liquid metal above the feeder opening is increased and dimensioned sufficiently for the feeding process, so that the feeder insert does not run empty during the feeding process. At the same time, the cross-section of the feed opening is covered by the liquid metal present in the inner cavity of the feeder body.
- the unequal mass distribution is achieved by forming different wall thicknesses on the feeder body, wherein the alignment of the feeder body lying below the dividing plane on the vertical model is achieved. gene region of the wall portion has a greater wall thickness than the above the dividing plane located portion of the wall portion of the feeder body.
- the invention can be realized with feeder inserts, in which the longitudinal axis of the feeder opening forms the center axis of the feeder body.
- a design of the feeder insert is possible in which the longitudinal axis of the feeder opening is arranged eccentrically to the center axis of the feeder body, as is already known from the generic EP 2489 450 AI.
- the feeder body is provided in its lid surface opposite the bottom surface with an opening extending inwardly of the feeder opening and aligned with the feeder opening for receiving a shaping mandrel attached to the casting mold inserted into the casting mold so that the feeder insert is already in front the shaping can be pushed over the mandrel so that the feeder insert does not slip off during the molding process.
- the feeder insert is then further displaced in the direction of the longitudinal center axis of the feeder insert or of the mandrel carrying it in the direction of the model carrying the mandrel. It can be plugged onto a rigid mandrel or on a so-called spring mandrel in a conventional manner, the feeder insert.
- the feeder body consists of two halves split along a transverse axis extending at a pitch angle to its longitudinal axis and assembled to form the feeder body.
- a preferably made of metal and a aligned with the feeder opening of the feeder body passageway having molding is fixed, as is known from the generic
- EP 2489450 AI is known.
- the molded part performs the same task as in a feeder insert inserted into a horizontally split mold.
- FIG. 1 shows a feeder insert in a position associated with a vertical mold half in a lateral sectional view
- Figure 2 shows the subject of Figure 1 with a his Feiserfuß forming
- the feeder insert 10 shown in FIG. 1 has a feeder body 11 which comprises a wall region 13 enclosing an inner cavity 12 as a so-called feeder volume and a lid region 14.
- the feeder body has an outer surface 16 and an inner surface 15 surrounding the inner cavity 12 of the wall region 13 and a bottom surface 17 in which a feeder opening 18 is formed.
- the feeder insert 10 which is shown in a "lying" arrangement, is intended to be associated with a vertical mold half 20, for which purpose the feeder insert can be plugged onto a forming mandrel, not shown, formed on a model inserted into the casting mold extends into the lid portion 14 of the feeder sleeve 10, wherein in this lid region 14 is formed an opening 22 for receiving the tip of the shaping mandrel.
- the tip of the Aufformdorns' is the radical cross section of the lid portion in the opening 22 pierces.
- this is also known from the prior art.
- the region 26 of the wall region 13 coinciding, imaginary and extending into the plane of the drawing, above the longitudinal axis 21 of the feeder opening 18, which simultaneously forms the longitudinal center axis of the feeder body 11 in the embodiment shown in the drawing a significantly thin material thickness and thus significantly less mass than the located below the parting plane 25 region 27 of the wall portion 13 so that the unspecified in the drawing center of gravity of the entire wall portion 13 of the feeder sleeve 10 is located below the dividing plane 25 anyway.
- the inner cavity 12 of the feeder insert 10 is asymmetrically designed with respect to the longitudinal axis 21, wherein the area 28 of the inner cavity 12 situated on the opposite side of the center of gravity of the graduation plane 25 has a larger volume than that on the side of the graduation plane 25 facing the center of mass
- the feeder insert 10 since the feeder insert 10 is in each case aligned when it is placed on a shaping mandrel such that the heavier region 27 of the wall region 13 is located below the longitudinal axis of the shaping mandrel, this inevitably leads to the region 28 of the inner cavity 12 with the larger volume is above the longitudinal axis 21 or division plane 25.
- Fig. 1 it can also be seen that for the sake of a simpler manufacture of the feeder body 11 consists of two along a perpendicular to the longitudinal axis 21 extending transverse axis 23 divided and assembled to form the feeder body 11 halves IIa, IIb, which can be produced in each case as individual parts are.
- FIG. 2 differs from the embodiment described above only in that on the bottom surface 17 of the feeder insert 10, a preferably metallic molding 30 is disposed and preferably connected to the bottom surface 17 by gluing, which is a hat-shaped or cylindrical shape and a with the bottom opening 17 of the feeder insert 10 aligned passage opening 31 has.
- a preferably metallic molding 30 is disposed and preferably connected to the bottom surface 17 by gluing, which is a hat-shaped or cylindrical shape and a with the bottom opening 17 of the feeder insert 10 aligned passage opening 31 has.
- Such a design including such a molded part 30, which may also be deformable in itself, corresponds to the generic state of the art.
