Definitions

the invention relates to a feeder insert for insertion into a mold used in the casting of metals, comprising a feeder body having a feeder body of an exothermic and / or insulating material with a lower, the casting forming the forming region of the mold, provided with a bottom opening bottom surface, wherein on the feeder body a relative to the feeder body movable and when forming the feeder insert in the production of the mold via the bottom opening in the feeder volume insertable feeder base, in which one of the formation of the predetermined breaking point for forming in the feeder volume with Feiserunterteil feeder remainder serving feeder opening is formed and the feeder insert with feeder base during manufacture of the mold can be attached to a holding mandrel attached to the model forming the casting mold.
a feeder insert with the aforementioned features is in the EP 1 184 104 A1 described.
the known riser lower part is first placed on the retaining mandrel or the model during installation of the feeder insert and has in its upper, the feeder body facing radially projecting retaining projections on which is placed in the assembly of the feeder insert in the mold to be produced, the feeder body and thereon auflagert.
the dimensions of feeder body and feeder base are matched to one another such that the feeder base can be inserted into the feeder volume of the feeder body as soon as the compressive force exerted on the feeder body during the production of the casting mold has caused the holding projections to break off from the feeder base.
the feeder insert is yielding to the continued pressure exerted form, because the rising on the model riser lower part can slide into the feeder volume of the feeder body.
This advantages such as elimination of a refractive core or waiving a so-called spring mandrel are connected.
the invention is therefore based on the object, a feeder insert with the generic features in such a way that its assembly is simplified when molded into a mold.
the invention provides in its basic idea that the feeder lower part is arranged in the ready position before inserting the feeder insert into the mold with upwardly facing bottom surface in the interior of the feeder volume and is movable in such a way that when turning the feeder insert in its position of use with its the molding area the casting mold facing bottom surface of the riser lower part with a portion of its longitudinal extent emerges from the feeder volume and the leaked portion in the manufacture of the mold back into the feeder volume can be inserted, and effective on the feeder body in its position of use, the complete falling out of the feeder base from the feeder volume preventing fuse is formed.
the feeder body consisting of feeder body and feeder base can be preassembled in its manufacture by the feeder base is first inserted into the feeder volume of the feeder body and then the backup against falling out of the feeder base from the feeder body to the feeder body is attached.
the feeder insert can be handled as a component during assembly of the feeder insert in an advantageous manner, wherein when turning the feeder insert into its position of use, in which the feeder insert is rotated in a facing with its bottom surface position that feeder base slips so far due to its own weight from the feeder volume, until the fuse formed on the feeder body becomes effective and holds the feeder base. In this mounting position, the feeder insert can be placed on the retaining pin.
the feeder lower part can be inserted again into the feeder volume by the same amount of its slipping out, so that the feeder insert as a whole is yielding in the manner known in the prior art.
the feeder lower part is designed as a molded body comprising an exothermic and / or insulating material, which has a connecting channel between the feeder volume and the casting mold.
the feeder base is completely accommodated in the feeder volume in the ready-to-reach position or the section of the feeder body is surmounted by a section.
the securing is formed as the cross section of the bottom opening located in the bottom surface of the feeder body after the insertion of the Feiserunterteilils in the feeder volume constricting material support, for example, the material support from set at the edge of the bottom opening points or from a may consist of adhesive material corresponding circumferential ring.
the fuse is designed as a cross-section of the located in the bottom surface of the feeder body bottom opening after insertion of the Feiserunterteils in the feeder volume narrowing, introduced into the bottom surface ridges. In all cases, after the onset of the feeder lower part in the feeder volume of the feeder body as part of the pre-assembly of the feeder insert the cross-section of the bottom opening narrowing fuse introduced so that above the feeder base is fixed to the feeder body.
the fuse is formed as a snap ring inserted into the wall region of the feeder body adjoining the bottom opening, the snap ring being in the snap ring in particular may be a snap ring according to DIN 9045.
the snap ring is inserted into the feeder body following insertion of the feeder base into the feeder volume and narrows the cross section of the bottom opening such that the feeder base is fixed to the feeder body above it. This is advantageously a very simple assembly of the feeder insert with feeder body and feeder base connected because only the snap ring must be provided and used.
the feeder lower part has at least one stop cooperating with the safety device in its region movable in the feeder volume, it being possible for the feeder lower part to have a conical section narrowing in the direction of the bottom surface of the feeder body and the stop is formed at the upper edge of the conical section.
the centering designs are designed as centering ribs which spring into the connection channel receiving the holding mandrel during manufacture of the casting mandrel and enclose the holding mandrel.
the feeder insert 10 initially shown in FIG. 1 has a feeder body 11 which comprises a wall region 12 surrounding a feeder volume 13, a cover region 15 and a bottom surface 14. In the bottom surface 14, a bottom opening 16 is formed. In the opposite lid region 15 is a blind hole 17 for receiving the tip of a retaining pin, as will be described.
a feeder lower part 18 is accommodated which has a conical section 19 which narrows in the direction of the bottom opening 16 of the feeder body 11.
a radially widening stop 20 is formed.
the feeder base forms a connecting channel 21, at whose bottom opening 16 of the feeder body 11 facing the end Feed opening 27 is.
the connecting channel 21 jump star-shaped centering ribs 22 a.
the fuse 23 may consist, for example, of a peripheral ring extending from the edge of the bottom opening 16 made of an adhesive material.
the feeder insert according to FIG. 1 is first rotated 180 degrees during its mounting on the casting mold to be produced, so that its bottom surface 15 now faces the molding region of the casting mold.
the lower part of the feeder 18 slips out of the feeder volume 10 into a position due to its own weight, in which the feeder lower part 18 is held on the securing 23 of the feeder body 11 via the stop 20 formed on it.
the fuse 23 need only be designed so strong that it carries the weight of the lower part 18 of the riser.
the feeder insert 10 is placed from a retaining mandrel 24, wherein the retaining mandrel 24 passes through the connecting channel 21 and is surrounded by the centering ribs 22 springing into it.
the feeder base 18 and thus the feeder insert 10 is fixed relative to the retaining mandrel 24.
the tip 25 of the retaining pin 24 thereby enters into the blind hole 17 formed in the cover region 14 of the feeder body 11.
the feeder body 11 is supported by the retaining mandrel 24 so that the protruding from the feeder body 11 chronic portion 19 of the Feiserunterteilils 18 bridges the distance between the model surface and the feeder body 11.
the set 26 is filled in the model box, thereby filling the between Model surface and feeder body 11 existing gap around the feeder bottom 18 around.
the feeder lower part 18 pushes into the feeder volume 13, so that under the action of the mold pressure destruction or deterioration of the feeder body 11 is avoided.
the lower part of the feeder 18 forms the breaking edge in the desired shape in the area of its feed opening 27 after removal of the model plate with holding mandrel 24.
the hot metal can flow through the connecting channel 21 of the riser 18 down to the feeder volume 13 or be sucked back from here into the mold.
