Definitions

the invention relates to a method and an apparatus for the production of molds for foundry purposes, which are composed of several interconnected molded parts, in particular also core parts, the individual molded parts being molded for themselves in a molding tool consisting of at least two partial boxes.
a generic method and a generic device are described in WO 87/07543, to which express reference is made, in particular also with regard to the actual production of the mold or core part.
the known device has conventional core molding machines, the number of which corresponds to that of the mold parts or core parts to be produced which are desired for a mold or a core.
a moving device is also provided with which the molded parts produced are in one of their part boxes be moved to a joining station in which they are assembled to the desired overall shape. Then the respective partial boxes move back into their molding machine so that a corresponding molded part can then be produced there.
the invention is therefore based on the object of providing a method and a device for producing cores which, while avoiding the abovementioned disadvantages, enable the production of molded parts to be improved with less outlay in terms of apparatus and design.
the above-mentioned object is achieved in the method of the type mentioned at the outset in that the tools are conveyed cyclically step by step by means of an endless conveyor, in that the shooting hoods assigned to them are conveyed synchronously with the tools and in that the shooting hoods move laterally into a shooting station common to them promoted position.
a device for the production of molds or cores for foundry purposes of the type mentioned is characterized by at least one discontinuously cyclically rotating tool conveyor for the molding tools, in each case a conveyor rotating in synchronism with this for shooting hoods adapted to the tools, and by at least one Tool conveyors assigned to a common firing station for several tools, in which the tools and associated firing hoods are guided offset from one another by their conveyors.
a (total) mold will consist of two molded parts, a basic or basic molded part and a final molded part, a core comprising a plurality of core parts being arranged within or between them. The number of core parts and - as a rule - two molded parts then determines the total number of molded and core parts for the (overall) shape to be assembled.
conveyors with ten tools are optimal.
conveyors with fewer, for example five, or more tools, for example twelve, can also be provided.
a further firing station may be provided, for example, on a device which is intended per se for the production of molds from a multiplicity of molded parts and can accordingly convey many tools can also be used if the device is to be used to produce molds which require significantly fewer individual molded parts, in particular equal to or less than half of the total tools provided on the conveyor. In this way, several forms can be produced simultaneously with a device according to the invention.
a major advantage of the invention is that the expensive and complex firing and gassing station need only be present in accordance with the number of overall forms to be produced, but not in accordance with the number of individual partial forms.
the shooting and gassing station is practically permanently in use and has no long downtimes.
the main movement of the tools can be carried out by means of a tool carrier in the form of a carousel in the form of a circular movement, which is kinematically more favorable than the entire back and forth movement of a parts molding box for all molded parts.
the conveyors for the tools and the firing hoods are rotary machines, in particular in the form of carousels which support the periphery of the tools and the firing hoods.
the revolving axes of the conveyors are arranged offset in the area limited by their circumference, but relatively perpendicular to each other.
the shot station has a shot boiler and fumigation carriage with a shot boiler and a fumigation hood which can be moved linearly above the tool located in the shot station, the shot boiler having devices for receiving and transmission of the firing hood is provided via the tool, further improvements being achieved in that the firing station is arranged radially to both axes of rotation or in that there are several mixing bunkers which can be brought centrally above into the positioning point into which these firing hoods are carried by the firing hood carrier to shoot the core molding material (sand) into the tools.
a transfer device for receiving pusher plates and removing them from the tools is provided in a station in front of the molding station, further developments provide that the transfer device has a swivel arm and that the gassing hood has a device for receiving and expelling the pusher plates .
An extremely preferred embodiment provides that the shooting station is followed by a device (transfer station) for removing a basic mold box with a molded part therein from the tool holder for the tools and for moving back into the area of open follow-on tools.
This embodiment is further characterized by devices for Holding shaped molded parts in top boxes of tools and for joining a molded part held in this way with molded parts held in a base box of another tool, possibly already assembled (package of molded parts).
the device and the corresponding process sequence according to the invention have the further advantage that, apart from the basic mold lower box, no further mold box parts, in particular no mold box part of the other tools from the cyclic or endless conveyor for the tools - which, as mentioned, is preferably designed as a circular carousel is - must be removed.
the joining is not carried out in a separate, remote joining station, as is the case with the prior art, but directly in the held tools themselves.
their individual boxes are only brought at a vertical distance from one another.
the opening and closing movements of the tools, which are required anyway, and the devices required for this, such as preferably hydraulic cylinders, are used to carry out the joining process itself.
the invention offers the advantageous possibility that a further conveyor, preferably in the form of a carousel, with its own firing and gassing station is assigned to the transfer station designed in this way at its end facing away from the first conveyor, so that parts to be joined alternately in the individual firing stations are molded and the individual molded parts are alternately brought from one conveyor or from the other conveyor to the transfer station and are joined there by moving the already assembled individual molded parts into the respective conveyor area.
a further conveyor preferably in the form of a carousel, with its own firing and gassing station is assigned to the transfer station designed in this way at its end facing away from the first conveyor, so that parts to be joined alternately in the individual firing stations are molded and the individual molded parts are alternately brought from one conveyor or from the other conveyor to the transfer station and are joined there by moving the already assembled individual molded parts into the respective conveyor area.
At least one of the endless conveyors has a further transfer station, so that when molds with a small number of molded parts are produced, the two devices also work independently of one another can.
This configuration offers the possibility of automatically producing molded parts with a high number of individual molded parts by working the two conveyors together, while, if desired, two molds, possibly of different types with a lower number of molded parts, can be produced in parallel independently on the machines.
the number of pieces will determine whether a rotary machine with a large number of tools and one or two molding stations or two rotary machines can be used with fewer tools and a common transfer station.
the invention also offers the possibility that if the molds are to be created from a number of molded parts that is greater than the number of molds of the device, individual molded parts may preferably be produced separately on separate molding machines and used separately in the transfer station.
the device according to the invention for the production of molds for foundry purposes initially has on a machine stand 1a (FIG. 2) a tool holder 1 in the form of a circular conveyor for the tools 2, which is arranged on the circumference of the tool holder 1 are.
the tool carrier 1 is rotatable about an axis of rotation 3.
the molded parts 5, 5a (FIGS. 4,5), in particular also core parts, are produced in the closed tools 2 in a manner to be described.
a shot cap carrier 4 for the shooting hood 6 Arranged above the tool carrier 1 is a shot cap carrier 4 for the shooting hood 6, which is also designed as a circular conveyor and rotates about an axis of rotation 7.
Tool carrier 1 and firing hood carrier 4 can preferably be designed as support arms, each driven by a precision and indexing table, on a slewing ring table for the tools 2 and firing hoods 6, respectively.
firing station 8 - the tools 2 carried by the tool carrier 1 and the firing hoods 6 correspondingly associated with each tool 2 are offset in the horizontal direction, that is to say perpendicular to their axes of rotation 3, 7, as can be seen from FIGS. 1 and 2.
an optimally compact device is achieved in that the two axes 3, 7 are offset from one another in an extension of the firing station 8 and the firing hood support 4 has a circumference which allows the desired number of firing hoods 6 to be accommodated. If one were to choose matching axes based on the latter, the desired offset in the shooting station 8 would result in a larger dimensioning of the entire device.
the shooting hoods 6 In the area diagonally opposite the shooting station 8 via the pivot points 3, 7 (at 9), the shooting hoods 6 essentially move above the respective tool 2.
the tools 2 consist, in a manner known per se, of a lower box 11, an upper box 12 and ejector plates 13 adapted to them.
each tool is assigned its own adapted shooting hood 6 which has weft channels (not shown) extending from a central shot opening 14, which lead to the shot holes formed in the upper tool 12 for ejector rods 16 of the ejector plates 13 and thus allow the molding sand to be shot in through them.
the firing station 8 has one or more mixing bunkers 21 (two in the exemplary embodiment shown), which can be moved from a standby position 22 into an operating position 23, which is located centrally above the position into which a firing hood 6 through the firing hood carrier 4 in the part Forming station is guided.
a shot boiler and gassing carriage 26 is arranged to be movable in the horizontal direction between the mixing bunker 21 arranged there and the shooting hood 6 supported there by the shooting hood support 4.
the carriage 26 carries, on the one hand, a shot boiler 27 and, on the other hand, at a distance corresponding to the horizontal distance from the shooting hoods and tools in the parts-forming station, a fumigation hood 28 which is provided with an ejection device 28a, by means of which it is gassed via an ejector plate 13 with ejector rods 16 can eject a shaped basic molded part from the upper box so that it remains in the lower box.
the ejector rods 16 on the ejector plate 13 push through the shot holes in the upper tool 12.
the shot boiler and gassing carriage 26 moves radially to both axes of rotation 3, 7 (ie in alignment with the same).
a storage plate 31 for the upper ejector plates 13 is arranged radially outside the tools 2 at a distance which corresponds to the horizontal distance already mentioned between the firing hood and tools or firing kettle 27 and fumigation hood 28 on the carriage 26.
a transfer device 32 for the ejector plates 13 in front of the shooting station 8 such that the device 32 with a swivel arm 33 in a tool position in front of the shooting station 8 receive the ejector plate 13 belonging to the tool 6 located there and transfers it to the storage space 31 and can drop there.
the ejector plate 13 is pivoted relative to the transfer movement of the arm 33 relative to the arm 33 in such a way that its outside always, i.e.
a transfer station 41 is located in the direction of rotation A behind the firing station 8.
the transfer station 41 has a transfer carriage 42 for receiving one of two basic mold lower boxes 11a (transfer boxes) of a basic tool.
11 lifting devices 43 and for the upper tool boxes ejectors 44 are also provided for the lower tool boxes, which are hydraulically actuated, as are also the other horizontal and vertical linear movements mentioned hydraulically by the hydraulic cylinder indicated in the drawing.
a removal station 51 is assigned to a further standstill position of the tools 2. This also has a radially movable carriage, namely a removal carriage 52 for the basic form lower box 11a and in the retracted position of the removal carriage 52 has an ejector 53 for ejecting the mold or cores located therein.
a lifting device 54 is also provided in the path of the tools 2 required by the tool carrier 1 below the lower box.
the assembled molds or cores in the removal station can either be removed by hand, if necessary using aids, or it is a known removal device for the composite shapes and cores provided.
the two carriers 1, 4 rotate synchronously. If the tool 2 with the basic form lower box 11a now arrives in the station 34, the arm 33 grips the associated individual upper ejector plate 13 conveyed with the tool 2 in this station and transfers it to the storage space for the ejector plate 13 in the manner described. At the same time, the rest of the tool from the basic-form lower box 11a and upper box 12 and the associated firing hood 6 move further into the firing station 8.
the shot boiler 27 was filled with sand from the mixing bunker 21 moved over it.
the shot boiler and gassing carriage 26 picks up the shot hood and moves it with the shot boiler 27 via the tool 2. This is then closed by the lifting device 17 by the lower box 11 or 11a can be lifted against the top box 12 and both together against the underside of the shooting hood 6 and together with this against the shooting bowl 27.
the sand located in the shot boiler 27 is distributed in a conventional manner through the shot hood 6 and through its channels and the shot holes in the upper box 12 into the interior of the tool 2.
the gassing hood picks up the ejector plate 13 from its storage space 31.
the gassing hood 28 with the ejector plate 13 is moved over the tool 2 and placed thereon with its peripheral edge in a gas-tight manner.
the gas is then gassed with a catalytically active gas, which activates a binder added to the sand and thereby causes the sand-binder mixture to solidify in the tool.
the tool 2 and then the lower box 11a are then lowered in a further work step relative to the upper box 12 (by means of the cylinder 18a), as a result of which the ejector plate 13, which is in the closed state of the tool is supported with rods or feet on the lower box 11a, is released and with its ejection rods 16 simultaneously with the downward movement of the basic lower box 11a, the shaped basic molded part 5a or the basic core) is released from the upper box and into the basic lower box 11a presses.
the ejector rods 16 are spring-loaded upwards for safety reasons, this can be done by applying additional force, for example by additionally pressing down an ejection piston 28a located in the gassing hood 28.
the fastened basic molded part 5a is then located in the basic lower box 11a.
the sub-box in question is the base or base sub-box 11 a with a basic molded part, which comes to lie at the bottom in the overall form to be composed of a plurality of molded parts 5, 5 a, then this is picked up by the transfer carriage 42 and in the transfer station 41 move radially outwards together with the basic molded part 5a located in it.
the associated upper box 12 and the receptacle on the tool carrier 1 enter the removal station 51 and take over from there a second, identical basic box 11a.
two basic-shape lower boxes 11a are used, while the other lower boxes 11 and upper boxes 12 and shooting hoods 6 are only present once.
the molded part 5 is then brought into the transfer station 41 with the tool 2 open and adhering in the upper box 12.
the transfer carriage 42 moves the basic molding 5a previously transferred to it in the basic mold lower box 11a with the latter into the opened tool 2 and in particular under the subsequent molded part 5 held in its upper box 12.
Basic mold lower box 11a and upper box 12 with the corresponding molded parts 5a, 5 are now brought together, for example by lifting the basic shape lower box 11a indirectly against the upper box 12 by the lifting device 43 of the transfer station 41 by means of the lower box 11 located there.
the ejector 44 presses the ejector plate 13 with its ejector pins 16 downward, so that the molded part 5 initially located in the upper box 12 is pressed out of the upper box 12 when the basic mold lower box 11a and the basic molded part 5a located therein are lowered and with the basic shape -Lower box 11a and in this molded part 5 is lowered.
the second molded part was thus connected to the basic molded part 5a.
the tool for the second molded part passes through the removal station 51 without any process operation taking place there. All other molded parts 5, from which the shape to be ultimately created is assembled, are produced in the same manner described and connected to the molded parts 5, 5a previously assembled in the basic mold lower box 11a.
the transfer carriage 42 does not take the basic shape lower case 11a carrying the shape out of the tool carrier 1 again, but rather brings the basic shape lower case 11a with the entire mold assembled in it for the removal station 51 (as shown in FIG. 5).
the removal carriage 52 of the station takes over the basic form lower box 11a together with the form in it from the tool carrier 1 and moves it radially outwards.
the finished assembled mold is then ejected from the basic mold lower box 11a by means of the ejector 53 and the finished assembled mold can be removed from the device according to the invention in the manner already indicated above.
the second basic-shape lower box 11a has returned to the transfer station 41 and has been removed from the tool carrier 1 therein.
a tool carrier element with a missing basic shape lower box 11a enters the removal station 51, so that the first basic shape lower box 11a located there is brought back into its place in the tool carrier 1 by the carriage 53.
the first basic mold lower box 11a is thus ready for molding a further basic molded part.
the device shown includes a carousel of ten, in which ten molded parts to be assembled into a mold can be molded with a shot station 8.
the invention Device optimized in terms of construction and operational technology, that is, an optimal size was selected, with which in most of the molds to be produced, all of the molded parts 5.5a can be produced with the device.
the device according to the invention also offers the possibility of producing molds with more than ten molded parts by feeding and using molded parts produced either on another or other conventional molding machine either by hand or in the manner given in WO 87/07543 in the transfer station 41 can be or the illustrated transfer station 41 is at the same time a transfer station for a further device according to the invention with a tool carrier 1 in the manner described with ten or fewer tools, so that in the manner described with this second carousel and its associated firing station 8 the corresponding parts in shaped in the manner described and the overall shape can be assembled from the individual molded parts in the common transfer station 41.
tool carrier carousels with fewer tools can also be used.
the position of the transfer station 41 and immediately after it the removal station 51 near the firing station 8 is desirable, it is not necessary. Accordingly, for example, a first transfer station 41 can be provided in a device according to the invention, which is a common station for two tool carrier carousels. A further transfer station to which no further carousel is assigned can be provided behind this in the direction of movement. Of course, there will also be a removal station.
two tool carrier carousels for creating Molds with several individual parts can work together, or they can independently create molds with fewer individual mold parts, one of the transfer stations being used by a carousel, which need not have any more, while the other transfer station 41 is only used by the carousel to which it is assigned .
the arrangement of the tool carrier and the firing hood carrier is the optimum in the manner explained at the beginning of the description of the figures, both can also be arranged concentrically to one another or offset such that the path of their peripheral edge does not intersect, but rather the firing hood 6 in the region of the Shot station 8 is brought up from the outside.
the design shown is the optimal one.
the endless conveyor carrying the tools 2 and the shooting hoods 6 does not have to be designed as a circular conveyor or carousel, but can also include, for example, a conveyor chain or the like which surrounds a rectangle, square, oval, an ellipse or the like and which contains the corresponding holders for the Tools 2 and the shooting hood 6 carries.
FIGS. 5 and 6 Further preferred refinements of the device according to the invention for carrying out the method according to the invention are shown schematically in FIGS. 5 and 6. Insofar as individual parts basically match, they are identified by the same reference numerals as in FIGS. 1 to 4. If individual elements are not shown in detail in FIGS. 5 and 6, they can in principle be designed as shown in FIGS. 1 to 4 and described with reference to these figures.
the tool carrier 1 is designed as a roller conveyor for the tools.
the tool conveyor 1 is designed as a rectangular endless conveyor, in which the tools rotate.
the shooting hood support 4 which is also designed as a rectangular roller conveyor for the shooting hoods 6.
the webs 1, 4 are also offset in height here. While in the illustrated embodiment of FIG. 5 the firing cap holder 4 is arranged entirely within the tool holder 1, it could also be guided in the rear part (above in FIG. 5) over the part of the tool holder 1 there.
the shooting station 8 is also shown schematically. In contrast to the embodiment of FIGS. 1 and 2, in which the tools 2 which have been molded into them are conveyed by the tool conveyor 1 to a transfer station 41 separate from the firing station 8, the transfer station 41 is in the embodiment of FIGS. 5 and 6 arranged directly at the shooting station 8.
the transfer station 41 Separated from the tool conveyor 1, the transfer station 41 is followed by a tray 61, from which the mold packages produced can be conveyed directly into a casting installation 62 and from there via a tray 63 for the casting for further processing of the cast parts.
the workflow is basically the same as described with reference to Figures 1 to 4.
the basic shape is then produced in the manner described with reference to FIGS. 1 and 2.
the lower box and the upper box of the basic tool are separated from one another in the shooting station 8, the shaped basic molded part just remaining in the above-explained manner, which is moved out of the shooting station 8 perpendicularly to the tool carrier path 1 by a transfer carriage of the transfer station 41 , while the associated upper tool is conveyed along the tool carrier path 1.
the next tool 2 is conveyed into the firing station 8.
the core part to be produced in this tool is produced in the manner also described above. After production, the tool is opened by separating the lower box and the upper box, whereby the core part produced is ejected from the lower box and remains in the upper box.
the base part with the base part located in it can be inserted into the opened next tool by the transfer carriage of the transfer station 41.
the core part produced in this is ejected from its upper box and with the basic form lower box and the one located in it Basic part moved out of the shot station 8 by the transfer station 41.
the lower and upper box of the second tool are then conveyed out of the firing station 8 along the tool carrier path 1.
the production of the further core and molded parts as well as the assembly of the individual parts to the overall shape is then carried out in basically the same way. For details, reference may be made to the explanation of FIGS. 1 to 3.
the entire mold After the entire mold has been produced, it can be conveyed in the direction of arrow A to the storage for the core package 61 and from there then for casting the casting into the casting installation 62, from which the casting, optionally after intermediate storage (63), in the direction of arrow C the device is advanced. Then the upper box of the first tool again arrives at the shooting station 8, where the basic mold lower box, freed from the core package, is also retracted into the shooting station 8, so that the subsequent molded parts for another core package and this can be produced. If necessary, it is also possible to work with two basic shape lower boxes for an associated upper box in the manner described above.
the procedure in the embodiment of FIG. 6 is fundamentally the same, the tools 2 and the firing hoods 6 only being moved back in the opposite direction to the original conveying direction during processing after the production of all molded and core parts and of the core package composed of these. If the upper box of the first tool is moved through the firing station 8, the associated basic shape lower box is simultaneously brought into the firing station by the transfer station 41 and brought together with the upper box. Then in the same In turn, the individual mold and core parts for the next mold or core package and this are manufactured.
FIGS. 5 and 6 are surrounded by a housing 66.
FIGS. 5 and 6 reference can in principle be made to the explanation for FIGS. 1 to 4 for a preferred embodiment thereof.
