Definitions
- the invention relates to a casting tool for producing a piston according to the preamble of claim 1.
- the invention also relates to a corresponding method for producing such a piston.
- Fluid energy machines perform in the piston in cylinders transmitted via push rods periodic translational movement, are known in mechanical engineering as reciprocating engines.
- the most common type of piston engine represents the reciprocating engine, which converts the change in volume of a gas in the described linear movement of the piston and a connecting rod and a crank further into a rotational movement.
- the piston comprises a combustion bowl for this purpose.
- Suitable pistons are produced according to the prior art regularly by means of a primary molding process, in particular by means of specialized casting techniques.
- the problem here is the compensation of the occurring during operation of the engine extremely high thermal load in the edge region of the combustion bowl, which can lead to the formation of cracks in the piston under unfavorable conditions.
- the trough edge is also reinforced by the pouring of ceramic fibers.
- the squeeze casting method or a robot-assisted medium-pressure casting method (RMD) is sometimes used for this purpose in order to ensure the complete infiltration of the ceramic fibers through the aluminum melt and thus the integration of the ceramic fibers in to favor the metal structure.
- a corresponding method is known from DE 10 2004 052 231 A1 and the corresponding disclosure of EP 1804 985 B1. Both documents relate to a method for mass production of a piston, wherein a casting melt is filled via a feed into a multi-part mold with a casting bottom and at least one feeder, wherein it is provided that after the casting of the piston blank, the opening of the upwardly open end of the feeder sleeve is acted upon by a gas pressure acting on the casting melt. The tightness of the feeder is ensured by the use of a so-called collar feeder.
- An embodiment of this method is characterized in that after filling the piston casting tool, the formation of a peripheral shell of solidified casting melt is awaited. Due to a special design of the casting bottom and the feeder sleeve, a collar forms around the feeder in this solidification phase, so that a sealing surface is created between the mouthpiece of the feeder and the collar which holds the feeder contents in position.
- Critical here is a dense pressurization of Senater- materials, which usually consist of heat-insulating and mechanically less resilient materials such as ceramics.
- the formation of an edge shell in the feeder occurs functionally delayed with respect to the casting tool.
- the invention is therefore based on the object to provide an improved casting tool to produce high-quality piston in a robust casting process for pistons.
- the invention is therefore based on the idea of supplementing a casting bottom used in the casting process by a preferably annular groove surrounding the feeder or a preferably annular collar surrounding the feeder which is also arranged radially spaced from the feeder.
- the pouring melt fed into the casting mold by the feeder or an inlet can, for example, solidify in this groove to form a circumferential sealing rib, whose inner flank sealingly bears against a corresponding inner flank of the groove.
- solidification shrinks especially at different coefficients of thermal expansion, such as between an aluminum melt and a steel mold, the casting on the groove flank on.
- the high thermal conductivity of the steel causes a rapid cooling and solidification of the melt at the contact points, which can lead to directional solidification to form a fine, columnar-solidified microstructure.
- the still liquid part of the casting melt is held by the surface contact between the two flanks in a preferred, but unnecessary pressurization of the melt by the feeder in position and prevented from premature emergence from the Bodenkokille.
- the groove surface acts as a pressure-tight surface when pressurized by the feeder. This is particularly advantageous if the good thermal insulation of the feeder the melt in the feeder has not yet formed a stable marginal shell and thus the liquid melt can infiltrate by the pressurization by the feeder porous inserts, for example, to Muldenrandbewehrung.
- the circumferential groove or the circumferential collar is radially spaced from the feeder and separated from this, so that the feeder is not burdened by solidification of the casting melt by shrinking the casting melt, as this For example, in the feeder from DE 10 2004 052 231 A1 the case.
- the casting tool according to the invention for a piston comprises the mentioned mold for forming the piston from the casting melt, the casting tray with the centrally located feeder for feeding the casting melt into the casting mold and a pressure gas line opening into the feeder for compressing the casting melt within the casting mold.
- the pouring tray is either the circumferential around the feeder and this radially spaced, preferably annular, in particular annular groove and / or provided around the feeder and radially spaced to this, preferably annular, in particular annular collar provided.
- the groove has an inner groove flank for molding the casting melt into an annular sealing rib such that an inner rib flank of the sealing rib sealingly abuts the inner groove flank when the cast melt solidifies in the groove whereas the collar has an outer flank flank for molding the casting melt annular Has sealing groove such that an outer groove edge of the sealing groove sealingly abuts the outer collar edge when the casting melt solidifies.
- a suitable aluminum alloy as cast melt may be considered.
- properties such as hardness, vibration absorption, toughness and machinability of the piston blank for mechanical processing can be selectively influenced.
- an aluminum-silicon alloy has been found to be a light metallic cast melt that has its eutectic at a bulk level of approximately 12% silicon. Nevertheless, a hypoeutectic or slightly hypereutectic mixing ratio is recommended for the proposed method, which gives the resulting aluminum alloy a solidification range in which a small proportion of solid phases is already present in addition to the casting melt.
- the sealing effect of the solidifying rib according to the invention is achieved early in this way.
- the addition of a proportion by mass of up to 6% copper, up to 3% nickel and up to 1% magnesium may also be considered effective in order to further increase the strength of the piston blank. All alloying proportions are given in% by weight.
- the invention is further based on the general idea, in a method for producing a piston by means of a multi-part casting mold to fill a casting melt via a separate inlet of the casting tool, wherein the casting melt is pressurized by means of a pressure gas line opening into the feeder within the casting floor.
- the casting melt solidifies in an annular groove surrounding the feeder in the casting bottom and radially spaced therefrom such that an inner rib flank of the sealing rib abuts sealingly on an inner groove flank of the groove of the piston casting tool.
- a collar may be provided on the casting bottom, so that the casting melt solidifies at this circumferential and radially spaced from the feeder collar to an annular sealing groove, that an outer groove flank of the sealing groove sealingly against an outer collar flank the collar of the Kolbeng madtechnikmaschines rests.
- Both embodiments have in common that when a solidification of the casting melt no mechanical stress is exerted on the feeder by shrinking, but the shrunk casting is supported by a force exerted on the sealing surface pressure force directly on the casting floor and thereby causes sealing along the sealing surface.
- a particularly favorable embodiment results when the collar of the bottom mold is already carried out as close as possible contoured to the shape of the later combustion bowl, in particular of the bowl rim and neck.
- the proposed production process is carried out as a gravity mold or low-pressure casting process under a pressure between 0.3 bar and 20 bar.
- a full full mechanization is made possible by means of suitable robots, which can increase the casting performance considerably.
- a casting tool 1 according to the invention for a piston 2 has a casting mold 3 for molding the piston 2 from a casting melt 4 (see Fig. 2).
- the casting mold 3 has a casting bottom 5 with a preferably centrally arranged feeder 6 for feeding the molten casting 4 into the casting mold 3 and a pressure gas line 7 opening into the feeder 6 for compressing the molten casting 4 within the casting mold 3 (see Fig. 2).
- the feeder may be formed of ceramic, for example.
- a groove 8 which is arranged in the casting bottom 5 and extends annularly around the feeder 6 and is radially spaced therefrom, is provided with an inner groove flank 9 (see Fig. 4a) for shaping the cast melt 4 into an annular sealing rib 10 such that an inner rib flank 1 1 of the sealing rib 10 sealingly abuts the inner groove flank 9 when the molten casting 4 solidifies in the groove 8.
- an annular collar 12 which is arranged in the casting bottom 5 and extends annularly around the feeder 6 and is radially spaced therefrom, can also be provided (see FIGS.
- the groove 9 or the collar 12 is arranged radially on the outside, whereas it is arranged radially inwardly according to FIGS. 2 and 6, that is to say has a smaller radial distance from the feeder 6, than that shown in FIGS 1 and 5, shown as an alternative.
- a ring collar 12 may be provided, as shown in Figs. 3 and 7, is shown. Again, it is conceivable that the annular collar 12 is arranged further outward or further inward, wherein there is always a distance from the feeder 6.
- the groove flank 9 or the collar flank 13 can have an angle of inclination ⁇ of between 3 ° and 20 °, preferably of 10 ° to 15 °, relative to a perpendicular 16 on a surface of the casting floor 5.
- the angle of inclination ⁇ is small enough to be selected in order to ensure a secure hold of the shrunk-on casting on the sealing surface with regard to the coefficient of friction.
- the inclination angle ⁇ should still be sufficiently large to allow easy stripping of the finished cast piston 2.
- this geometric shape ensures that the sealing rib 10 or sealing groove 14 formed after hardening of the casting melt 4 in turn defines an inner rib flank 11 or outer groove flank 15, which rests flat against the inner groove flank 9 or outer flank 13 and the casting floor 5 or the Bodenkokille thus seals against premature and unwanted leakage of the casting pressure, thus allowing a proper determination infiltration of the porous inserts.
- a piston 2 can be produced as follows: First, the casting melt 4 is fed via the inlet 21 into the casting bottom 5 and above into the casting mold 3 of the casting tool 1, wherein the casting melt 4 is conveyed by means of the compressed gas line 7 opening into the feeder 6 is pressurized within the casting floor 5 in order to avoid voids formation and to infiltrate porous Eing manmaschine. When pouring the molten casting 4 into the casting mold 3, this also enters the feeder 6 in the casting bottom 5 annularly circumferential and radially spaced from this groove 8 and solidifies into an annular sealing rib 10, wherein the respective inner rib flank 1 1 of the sealing rib 10 tight on the inner groove flank 9 of the groove 8 applies (see Fig.
- the casting melt 4 also at the the feeder 6 in the casting bottom 5 annular and radially spaced from this annular collar 12 such solidify to form an annular sealing groove 14 that an outer groove edge 15 of the sealing groove 14 sealingly on the outer collar edge 13 of the annular collar 12 is present.
- the casting melt 4 is to be pressurized after filling the mold 3 and before complete solidification of the casting melt, at the earliest after filling the mold 3 and after the partial solidification of a peripheral shell of the piston and portions of the inlet 21st
- a porous insert 18 there (see FIGS. 5 to 8).
- the piston may contain other, not to be infiltrated inserts, such as ring carrier or salt cores to form cooling channels.
- the insert 18, in particular a ring carrier or a trough edge protection may for example be porous and be infiltrated by means of pressure applied to the casting melt 4. At the same time, the infiltration can be assisted by generating a negative pressure by means of suction lines 20.
- Casting melt 4 is in particular a near eutectic aluminum alloy, which comprises a mass fraction of 10% to 14% silicon and / or a further mass fraction of up to 6% copper, up to 3% nickel and / or up to 1% magnesium.
- other elements such as V and Zr (each ⁇ 0.2%), and for grain refining eg Ti ( ⁇ 0.2%) and P ( ⁇ 0.01%) are added.
- a near-eutectic or even hypoeutectic interpretation of the AlSi alloys has been shown.
- a casting melt is preferred, which is largely free of impurities by low-melting elements with a Melting point ⁇ 490 ° C, such as Pb, Bi, Sn, Zn, wherein the concentrations of these elements individually each below 0.01%.
- the casting of the piston 2 takes place by gravity die casting or low-pressure casting method, the solidification of the casting melt in the mold, in particular under a pressure between 0.3 bar and 20 bar.
- the casting melt 4 described is introduced into the casting tool 1 via the inlet 21 so that the free areas of the casting mold 3 are filled with molten casting 4 around a core 19, which later forms the small connecting rod eye of the piston 2.
- the special design of the pouring tray 5 and feeder 6 allows the formation of the food content in holding the sealing rib 10 and sealing groove 14 when the casting mold for the realization of short cycle times according to the method is opened at a time at which the content of the feeder 6 is still partially liquid inside can be.
- the stabilizing effect of the sealing rib 10 or sealing groove 14 is supported by the invention essential to the feeder 6 in the casting bottom 5 circumferential groove 8 and in the complementary embodiment by the annular collar 12, within which the casting melt 4 to form the annular sealing rib 10 and Sealing groove 14 solidifies.
- the casting melt 4 can rise to a desired extent, so that above the filled casting melt 4 after the completion of the supply of molten casting 4 within the feeder 6, a free space is created over which the casting melt 4 with a gas pressure between 0, 3 bar and 20 bar is applied.
- the gas for pressurization is supplied to the feeder 6 via the compressed gas line 7, which is open during the filling process of the molten casting 4 with respect to the environment, so that a pressure equalization can take place (cf., Fig. 2).
- the compressed gas line 7 is for the sake of simplicity only in Fig. 2 and the inlet 21 and the sleeve 22 are shown only in Fig. 8, it being understood that they may be present in other embodiments.
