- she has a portal-shaped frame on which a rotary table is freely rotatable is.
- a two-arm boom is attached to it, the free one
- Each end is arranged a manipulator for handling molds.
- the axis of rotation determined by the turntable is in the direction of rotation of the turntable seen successively a core insertion station, a casting station with a melting furnace, a removal station and a sizing station.
- the core loading station and the removal station are located opposite one another diametrically opposite, as well as the casting station and the finishing station.
- a drive interacting with the rotary table via an indexing gear moves the diametrically opposite one during a working cycle Manipulators in turn to each of the above workstations, whereby the working cycles of the two manipulators are identical, but by one half cycle are shifted against each other.
- the insertion of the cores and the casting process are related to the removal of the castings and immersing the molds in a sizing bath Operations.
- the each at the removal station or the The manipulator located in the finishing station can only go to the next workstation be rotated further when the core insertion operation or the casting process is finished. This leads to considerable cycle times.
- the removal station is a service station assigned to jet cleaning the mold parts. Must now a mold is cleaned after a certain number of working cycles the other manipulator during the cleaning time at the core loading station stand. There is therefore no production during this time.
- the low-pressure mold casting device enables short cycle times due to long-term operations at two workstations can run simultaneously.
- the low-pressure mold casting device shown in the figures has Portal-like frame 10 with four vertical supports supported on the foundry floor Columns 11 on top of each other by means of longitudinal and cross members 12, 12 ' are connected. On the side members 12 is a horizontal support plate 14 attached, on which two rotary tables 16, 18 are arranged. The common vertical axis of rotation of the two Rotary tables 16, 18 arranged one above the other are designated by 20.
- the ring-like lower Rotary table 16 is arranged - compare in particular Fig. 3. On this also sits coaxially to the axis of rotation 20 of the same design second Axial ball bearing 24 on which the upper turntable 18 is arranged.
- the lower rotary table 16 fixed radially outer ring 22 'of the first axial ball bearing and the one with the upper rotary table 18 firmly connected radially outer ring 24 'of the second axial ball bearing 24 are provided with a circumferential spline 26, with which meshes a pinion 28 of an associated rotary drive 30 or 32.
- Each of the rotary drives 30, 32 has one from a control device 34 controlled, attached to the frame 10 electric motor with an indexing gear on whose output shaft the respective pinion 28 is seated.
- the support plate 14 has a circular passage 36, which from a support tube 38 'of a first support element coaxial with the axis of rotation 20 38 is reached with play.
- This support tube 38 ' is at the top at the bottom Turntable 16 attached to its radially inner edge.
- another support tube 40 'of a further support element 40 is arranged. This is with his attached to the upper end of the upper turntable 18.
- the two Support tubes 38 ', 40' end in a horizontal plane below the side members 12 and each have a recess set back towards the top on.
- each of these two arms 44 has parallel support profiles attached.
- the end region of each of these two arms 44 is a manipulator 46 same structure, see in particular Fig. 1.
- the recesses are designed such that the two manipulators 46 about the axis of rotation 20 can rotate relative to each other from about 80 ° to about 280 °.
- a rotating union 48 for the connection of the control device 34 coming control and feed lines with the manipulators 46.
- the part of the rotating union fixed to the turntable 48 with the manipulator arranged on the inner support tube 40 ' 66 rigid lines can be used, whereas for connection flexible lines are to be provided with the other manipulator, which the mutually different rotational position can take up.
- each of the arms 44 vertical profile of the manipulator 46 in the vertical Direction can be raised and lowered.
- a rail profile 52 At the lower end of the support profile 50 is a rail profile 52 about an axis of rotation 20 in tangential direction axis 54 rotatably mounted.
- the rail profile 52 is by means of a corresponding drive about the axis 54 from a horizontal direction to a vertical direction current position and swiveling back again.
- a cantilever-like support member 56 is fixed and on the other hand a carriage 58 to and from the support member 56 slidably mounted away.
- the distance between the axes 54 from the axis of rotation 20 is the same size and in 1 labeled R.
- the manipulators 46 can thus along a rotating circle 68 - see FIG. 2 - about the axis of rotation 20 to work stations 70 are moved. It goes without saying that these workstations 70 along the rotating circle 68 in the circumferential direction one behind the other are.
- FIG. 1 is a core insertion station 72 on the right and a casting station on the left 74 shown. As can be seen from Fig. 2, these are two Stations 72, 74 at an angle of approximately 160 ° with respect to the axis of rotation 20 arranged to each other.
- the casting station 74 has a melting furnace 76 known type with one arranged in a above the melting furnace 76 Pipe 80 opening riser pipe 80.
- the casting station 74 Seen in the direction of rotation D, the casting station 74 is followed by a removal station 82 with a conveyor 84 for those ejected from the mold 66 Castings and then a sizing station 86 with a sizing bath 88.
- the removal station 82 is to the casting station 74 and the finishing station 86 to the core insertion station 72 at an angle of approximately 80 °.
- the two Manipulators 46 relative to each other between about 80 and 280 ° the axis of rotation 20 can be rotated, they can be in neighboring Workstations 70 are located at the same time, with the exception of the removal station 82 and finishing station 86.
- FIGS. 4 to 8 The mode of operation of the low-pressure mold casting device shown in FIGS. 1 to 3 will now be explained in more detail with reference to FIGS. 4 to 8.
- Fig. 4 is one of the manipulators 64 in the casting position, where the in Mold parts 64, 64 'were in the closed position, as in FIG. 3 shown on the left, to which Giessmund 78 are lowered.
- the rail profile 52 is in a radial position.
- the mold 66 is moved through Lifting the support profile 50 lifted from the pouring mouth 78 and by driving of the assigned rotary table 16 or 18 to the removal station 82 spent. 5, the two mold parts 64, 64 'separated from each other by moving the carriage 58 in the open position.
- the castings become ejected from the relevant mold part 64, 64 ', which on the conveyor 84, for example a conveyor belt, fall.
- the manipulator 46 is now rotated and lowered over the size bath 88.
- the carriage 58 is in the open position Carrier 62 pivoted about the pivot axes 60 by 90 ° into a position in which they point away from the rail profile 52 at a right angle, whereby the Mold parts 64, 64 'while avoiding the formation of air cushions on the recesses immerse the mold parts 64, 64 'in the sizing bath 88, such as this shows Fig. 6.
- the manipulator 46 becomes again raised and the carriers 62 are in the aligned working position swiveled back.
- the two manipulators 46 are independent of one another about the axis of rotation 20 are movable, they can be simultaneously at the core insertion station and are at the casting station 74.
- the operations in these two Workstations 70 take significantly longer time than purging the castings in the removal station 82 and the immersion of the mold parts 64, 64 'into the sizing bath 88.
- the other manipulator 46 can follow End the pouring process from the pouring station 74 to the removal station 82 and then move to the sizing station 86.
- This manipulator 46 can then be rotated into the core loading station 72 when the other manipulator 46 leave the core insertion station 72 in the direction of the casting station 74 Has.
- the mold parts are after a certain number of work cycles 64, 64 'to be cleaned by irradiation, for example with brass shot.
- the manipulator 46 in question is brought into the service station 90 rotated.
- the mold parts 64, 64 'by means of the jet device 94 are treated, the production goes by means of the other manipulator 46 by turning in and against the direction of rotation D.
- this manipulator 46 of the core insertion station 72 against the direction of rotation D to the casting station 74 moved and lowered onto the pouring mouth 78.
- the manipulator 46 becomes the removal station in the direction of rotation D.
- the design of the low-pressure mold casting device outlined in the drawing has a very compact design. That included not enabled simultaneous placement of the two manipulators 46 in the The removal station 82 and the finishing station 86, however, lead to none or to an insignificant extension of a work cycle, because in these two Workstations 70 the time required is much shorter than in the Core insertion station 72 and casting station 74.
- a service station separate from the other workstations 70 90 brings the advantage that also while one of the manipulators 46 is in the service station 90, can be produced with the other manipulator 46. If this advantage is waived, the service station can of course 90, for example, can be assigned to the removal station 82.
