    57 A register system is provided for making molds for metal casting which reduces flaws attributable to parting line shift. This is accomplished by urging the cope mold flask (11) against two fixed stops (50, 52) on the long axis, and one fixed stop (54) on the short axis of the flask. This same register principle is applied in the drag mold making station (18), where the drag flask (15) is urged against two fixed stops (100, 102) on the long axis, and one fixed stop (90) on the short axis of the flask. At the closer station (24), where the mold halves are assembled, they are again urged against two fixed stops (134, 136) on the long axis, and one fixed stop (142) on the short axis of the flasks. Thus the flasks are properly aligned to the patterns at the mold making stations, and again properly aligned to each other at the closer station, so as to eliminate parting line shift problems of the mold halves.

    The invention relates to foundry production.
    The purpose of the invention is to improve the quality of the molds by preventing the half-form from moving along the parting line.

    3 assemblies of half-molds, Working position 4 of turning of the lower half-forms and clamps of the flask position: in the form of a pusher-Leu 5 and stops 6.
    Automatic line works in a consistent manner.
    Empty flasks 7, returned from the casting station, enter the conveyor 8, the molding of the upper flasks, where they are installed above the model board, are filled with the molding sand. The mixture is compacted at the work station 1 of the molding. In the same way, empty flasks 9, returned from the workplace, are cast, enter the conveyor 10 by molding the lower flasks, where they are installed above the board, filled with earth, the ground is compacted at the workplace 2 by molding the lower flasks. Lower flasks then pass the workplace
    4, where they are turned over so that the side of the model is facing up.
    After tilting, the lower mold halves 11 move along a conveyor 12 to the work station 3 of the mold assembly. During this movement, rods are installed in half-molds. On the workplace 3 assembly upper half of the form 13 raises

    Above the bottom flasks and positioned on them, forming a whole shape that has a horizontal dividing line, ready to move along the conveyor to the pouring workplace, where metal is poured into the mold. Movement is different. The conveyors 8, 10 and 12 are all coordinated so that they move together. Thus, for example, every 30 seconds (takt time) the flasks are advanced one step along the conveyor. Since the conveyor 12 carries half-molds in the direction along their long axis, the conveyors 8 and 10 move the half-molds along their short axis, the conveyor 12 must move accordingly a greater distance per stroke. Alternatively, the conveyor 12 may move continuously. In this case, at workplaces 1 and 3, a device is provided for synchronization with a continuously moving Kong. veier
    Figure 2-5 shows additional details of the workplace 1 forming the upper flasks. Upper flask 7 (Fig. 2) is installed on the -1 forming station in any suitable way, for example with grippers that can be lowered from the moving structure at the top. The grippers feed the flask 7 to the position above the model plate 14 and set it. The device from the cylinder with the piston 15 lifts the model plate 14 until it touches the bottom flange 16 of the flask. V. This time the positioning system accurately positions the flask relative to the model. After positioning the flask 7 on the model plate 14, the grips are lowered below and uncoupled, and the positioning system accurately positions the flask relative to the model. At this time, from the hopper 17, the flask is filled with molding sand. The hopper 17 is then retracted into the position releasing the flask, and the pressing mechanism 18 is inserted above the flask. The hopper 17 and the pressing mechanism 18 can be mounted on the same outboard mechanism (not shown), so that they can be in turn moved into the working and retracted position from opposite sides using appropriate means. The press mechanism 18 (Fig. 4) is lowered down until the upper surface of the molding sand touches the middle 31D54238.
    a cylinder with a piston, according to the model (FIG. 9). After installing the flask 9 and positioning on the model plate 31 (Fig. 7), the positioning system accurately positions the flask relative to the model. At this time, the hopper 33 fills the flask with the mixture. The ZZ bunker is then retracted so as not to interfere, and the pressing mechanism
    prior to contact with the surface of the moldable mixture, while shaking the flask 9 using a table 35 for sealing
    With the table 19, creating a CIM tag with a large force on this surface, and at the same time, the table 19 subjects the molding mixture to shaking or striking using appropriate means, for example using a pneumatic or hydraulic motor, thus sealing the 34 (FIG. 8) is placed above the flask. A press mixture that contains a sufficient owl mechanism 34 moves down a quantity of binder, such as clay, to form a semi-solid form inside the flask. The resulting α-semi-form, still in the flask, is then removed 15 mold sand. The resultant semi-working place 1 after the mold is then fed further to the worker, as a press mechanism, to the raised canting place 4 (Fig. 1), then upwards. The entire cycle ends with the lifting of the pressing mechanism, for a takt time of, for example, 30 seconds. Figure 9 depicts a workplace. Figure 5 describes the positioning system of 20 2 moldings of the lower mold. After taking on. Workplace 1 is mold-like empty flask 9 is lowered onto models. After the flask 7 is empty, the plate 31 and the grips 30 are unhooked, lowered onto the model plate 14 and a pair of stops 36 and 37 are used along the wadding 13, it is released, one side of the flask and a third stop 38. The pair of stops 6 and 20 along the side These stops (Fig. 5) are usually fastened on the ki, and the third stop 21 for precise fit or on the model holder. A pair of thickened flasks. The stops are usually ycta-hooks 39 and 40 used for turning on the model or holder of the flask in the correct position. Pair of pushers 5 to 22 use. the A cylinder unit with a piston 41 for moving the flask. To the support of the push rod 39, the frames are driven. A power cylinder with a piston 23 to move the box all the way down to the pusher 24 is then actuated to push the leg all the way to the stops 6 and 20. Then the piston 25 is actuated so that the pusher 26 shifts the side 7 until it touches the stop 21 and Now the flask 7 is precisely positioned relative to the boat, and then you can wait for the mold
    36 and 37. The cylinder 42 is then actuated so that the pusher 40 pushes the slide 9 up to the stop 38 into the stop. Now the flask 9 is precisely positioned relative to the model, and it is possible to mold the molding mixture in the flask and finish the molding. Plates 43-45 of hardened steel may
    Blend the mixture and mold the upper part 40 to be reinforced on the sides of the mold box 9 of the form. Plates 27-29 are hardened to interact with stops 36-38,
    so that they do not wear out quickly at these points. Stoppers can also be made from hardened steel. The 45 positioning system for the lower flasks is exactly the same as for the upper flasks, with the important difference that, since the lower flasks turn over at workplace 4 (Fig. 1), the stops 36 50 and 37 are in the lower part ( Fig.9) 4, while the stops 6 and 20 are located in the upper part (Fig.5). When the lower taps come to workplace 3 of the assembly (Fig. 1), the points of positioning-31 and stop. The cylinder with a piston-55 "upper and lower flasks 32 on the rack raises. the model will coincide on the flanges along the line of plate 31 until it touches the lower flange la.
    flasks. At this time, the positioning system. FIGS. 10-12 show the working position accurately positioning the flask with respect to 4 cants. A pair of sponges 46 and 47,
    Noahs may be reinforced on the sides of the flask 7 to interact with the lugs 6, 20 and 2.1 so that there is no wear at these points.
    Figure 6-9 shows the workplace 2 molding the bottom of the flask. Similar to what is done at the work station of the molding of the upper flask, the lower flask 9 is introduced into the workplace 2 in any suitable way, for example with the hooks 30 hanging from the upper structure. The grippers are brought by the flask 9 into position above the model plate.
    The flask 9 and positioning on the model plate 31 (Fig. 7), the positioning system precisely positions the flask relative to the model. At this time, the hopper 33 fills the flask with the mixture. The ZZ bunker is then retracted so as not to interfere, and the pressing mechanism
    34 (Fig. 8) is placed above the flask. The press mechanism 34 moves down the moldable mixture. The obtained half-form is then fed further to the workplace 4 canting (Fig. 1) after raising the pressing mechanism. Fig. 9 shows the work station 2 of the lower mold forming. After the empty flask 9 is lowered onto the model plate 31 and the grips 30 are uncoupled, a pair of stops 36 and 37 are used along one side of the flask and a third stop 38 These stops (figure 5) usually fasten on the model or on the model clip . A pair of pushers 39 and 40 are used to move the flask to the correct position. The cylinder assembly with the piston 41 for the pusher 39 is actuated to move the gaiter up to the stop against contact with the surface of the moldable mixture, while shaking the flask 9 using the table 35 for sealing
    34 (Fig. 8) is placed above the flask. The press mechanism 34 moves down the moldable mixture. The obtained half-form is then fed further to the workplace 4 canting (Fig. 1) after raising the pressing mechanism. Fig. 9 shows the work station 2 of the lower mold forming. After the empty flask 9 is lowered onto the model plate 31 and the claws 30 are uncoupled, a pair of stops 36 and 37 are used along one side of the flask and a third stop 38 These stops (figure 5) usually fasten on the model or on the clip models. A pair of pushers 39 and 40 are used to move the flask to the correct position. The cylinder assembly with the piston 41 for the pusher 39 is actuated to move the flask all the way to the stop 34 (Fig. 8) is placed above the flask. The press mechanism 34 moves down the moldable mixture. The obtained half-form is then fed further to the workplace 4 canting (Fig. 1) after raising the pressing mechanism. Fig. 9 shows the work station 2 of the lower mold forming. After the empty flask 9 is lowered onto the model plate 31 and the claws 30 are disengaged, a pair of stops 36 and 37 are used along one side of the flask and a third stop 38. 5 These stops (Fig. 5) are usually mounted on a model or on the holder of the model. A pair of pushers 39 and 40 are used to move the flask to the correct position. The cylinder assembly with the piston 41 for 0, the pusher 39 is actuated to move the box to the stop in the stop5
    36 and 37. The cylinder 42 is then actuated so that the pusher 40 pushes the slide 9 up to the stop 38 into the stop. Now the flask 9 is precisely positioned relative to the model, and it is possible to mold the molding mixture in the flask and finish the molding. Plates 43-45 of hardened steel may
    each on its axis 4b and 49 rotates, and both together relative to axis 50. When the half-mold 11 hits the work station 4 canting, the sponge 46 is in a horizontal position. (Fig. 10), s. sponge 47 is in the upper position (shown by dotted lines). After mounting the flask I on the lower jaw 46, the upper jaw 47 I rotates clockwise relative to the axis 49 so that the flask is firmly clamped or locked between the two jaws. The entire assembly then rotates approximately 180 counterclockwise with respect to the axis. 50 (Fig. 10) so as to put the flask on the level of the rail 12 (Fig. 1), and then the sponge 46 rotates upwards on the axis 48 (Fig. 11 ). The pusher 51 (Fig. 1) is driven by the action: and pushes the flask onto the conveyor 12. The sponges are turned back to their original position in order to be ready for the next flask coming from the work station 2 of the bottom flask forming.
    In workplace 3, the assemblies (Fig. 13) are connected. The top and bottom flasks. The bottom half of the mold 11 is fed to the assembly station by the conveyor 12. In the same way, the top half of the mold 13 is fed on top of the bottom half of the mold by means of clamps 52, .. Which are fixed to the top structure by any known method. Along the long axis, the positioning devices are connected to the flasks. A pair of pushers (Fig. 14 and .15) one by one move the flasks separately, pressing them against the stops. As in the workplaces of molding the upper and lower half-molds, they are the same. The plates 27-29 of hardened steel on the upper half-form and the corresponding plates on
