Definitions
- the present invention relates to a method and an apparatus for stepwise advancing moulds in a mould-string foundry plant of the kind set forth in the preamble of claims 1 and 4, respectively.
- mould-string foundry plants of this kind it is known to produce the moulds one at a time in the mould-making station and deliver the produced moulds to a precision conveyor, advancing the moulds stepwise to a pouring station, in closely juxtaposed position forming a mould string with casting cavities at the mainly vertical parting surfaces between successive moulds.
- Each step in the stepwise advancement of the mould string corresponds to the length occupied by one mould and the mould cavities are filled with liquid metal one at a time in the pouring station.
- the advancing of the moulds is partly performed by the mould-making station pushing a produced mould against the mould string, partly by advancing the precision conveyor, on which the mould string is positioned.
- the time available for the pouring is the standstill period for the stepwise advancement of the mould string, said standstill period being closely related to the production time of the mould-making machine.
- a foundry plant of this kind is e.g. known from EP-0,817,690.
- the stepwise advancing of the moulds is performed in steps corresponding to the distance occupied by two moulds and the mould- making machine is allowed to produce two consecutive moulds, i.e. two cycles for the mould-making machine, before the mould string is moved again, thereby substantially increasing the time for pouring relative to the time available when proceeding in the traditional way.
- Preferred embodiments of the method and apparatus e.g. comprising insertion of cores in the mould cavities, are revealed in the sub-ordinate claims.
- Figure 1 diagrammatically shows a mould-string foundry plant, in which the method in accordance with the present invention can be performed
- Figure 2 diagrammatically shows the sequence of operations in the mould-making machine during production in accordance with the present invention
- Figure 3 diagrammatically shows the movements of the squeeze plates in the mould-making station
- Figure 4 shows a sequence of operations corresponding to Figure 2 for a modified version of the apparatus in Figure 1 , in which cores can be inserted in the mould cavities,
- Figure 5 shows the movements of the squeeze plates corresponding to Figure 3 for the Figure 4 modification
- Figure 6 shows a sequence of operations corresponding to Figures 2 and 4 for a further modified version of the Figure 4 modification.
- the mould-string foundry plant shown in Figure 1 comprises a mould-making station A producing moulds one at a time for delivery to a precision conveyor C, advancing the moulds stepwise to a pouring station B, in which metal is poured 7 into the casting cavities formed at the mainly vertical parting surfaces between successive moulds. After pouring in the pouring station B, the mould string F is advanced stepwise to the extraction station E, in which the produced castings are taken out of the moulds.
- the mould-string foundry plant can further comprise a core-insertion station D for inserting cores into the mould cavities before closing thereof.
- the pouring station B is provided with two pouring units 7 in order to be able to pour metal into two mould cavities simultaneously.
- FIG. 2 The sequence of operations in the mould-string foundry plant shown in Figure 1 is shown diagrammatically in Figure 2.
- the mould-making machine is shown to the right diagrammatically comprising a mould-forming chamber 4 closed to the right by a squeeze plate 1 and to the left by a swingable squeeze plate 2 and comprising means 3 for introducing mould sand into the mould-forming chamber 4.
- the sequence of operations in Figure 2 is related to the movements of the squeeze plates 1 , 2, said movements being illustrated in Figure 3 indicating the speed of the squeeze plates as a function of time.
- the different operations of the mould-making machine are numbered op. 1-6.
- the mould string F is stationary during op. 1 - op. 4a and metal can be poured into the mould cavities in the pouring station B.
- the mould-forming cavity 4 is filled with mould sand from the sand hopper 3.
- the sand in the mould-forming cavity 4 is compacted by moving the squeeze plate 1 and the swingable squeeze plate 2 towards one another.
- the swingable squeeze plate 2 is moved to the left and swung out of the way, thereby opening the mould-forming cavity 4 ready for delivery of the produced mould, which is performed during operation op.
- the mould string F is moved one step further, over a distance corresponding to the length occupied by one mould in the mould string, whereafter pouring can be initiated in the pouring station B for the next two mould cavities to be poured.
- the operations op. 1 - op. 3 are performed as described above.
- Operation op. 4 is performed by moving the squeeze plate 1 at a relatively high speed until the produced mould 5 comes to the mould close-up position illustrated. The mould close-up is performed without moving the mould string F, due to the fact that room has been provided for the produced mould by the movement of the mould string F during operation op. 6, as described above.
- the operations op. 5 and op. 6 are performed and the sequence is continued from operation op. 1 as described initially. These operations are illustrated in Figure 2 down to operation op. 4a, where the pouring in the pouring station B is stopped.
- the time available for pouring metal into the mould cavities in the pouring station B is extended compared to the traditional method, in which the mould string F is moved one step forward during each delivery of a newly produced mould in operation op. 4b.
- the cycle time for the operations op. 1 , op. 2, op. 3, op. 4, op. 5, and op. 6 is reduced compared to the traditional operations op. 1 , op. 2, op. 3, op. 4a, op. 4b, op. 5, and op. 6.
- Figure 4 corresponds essentially to Figure 2.
- the time necessary for inserting the core may necessitate a certain delay between operations op. 2 and op. 3, as illustrated in Figure 5.
- the movements of the mould string can be performed as illustrated in Figure 6, which essentially corresponds to Figure 4 apart from the fact that the mould string F is moved the second step forward during operation op. 6, whereby the pouring in the pouring station B can be initiated immediately thereafter, and the core is inserted into the last produced mould during operation op. 2, as illustrated in Figure 6, thereby increasing the time available for pouring metal into the mould cavities.
