Definitions
- the invention relates to a molding machine with a Sand filling station and one in the transport direction of Molding boxes through a transport device after the Sand filling station arranged compression station, wherein between the sand filling station and the compaction station a vertical center column is arranged which is a turntable which is used for transport a mold box filled with sand together with a model plate and a filling frame from the sand filling station into the compression station and at the same time to transport an empty filling frame from the Compression station in the sand filling station Is rotatable 180 °, and with one lifting station each Area of the sand filling station and the compression station, the direction of transport at least in the area straight from sand filling station and compacting station and the mold boxes are shifted in cycles.
- Such multi-station molding machines previously known. It is also known in such Machine can run several processing steps simultaneously to let, for example, the filling of a Molding box with sand in a station of the molding machine and the compression of the molding sand in another Molding machine station. With the previously known machines it proves to be disadvantageous that one Large number of drive devices are required to transport the individual mold boxes and to to bring them into the molding machine in particular and dissipate from this.
- the CH-A-637 313 shows a molding machine in which hydraulic cylinders with push rods molded parts from one Transport path moved away and moved up on it again will. However, these push rods cause movement transverse to the transport direction of the molding boxes.
- the invention has for its object a molding machine of the type mentioned at the beginning, which with simple construction and simple, more reliable Applicability a transport of the mold boxes through the Molding machine with minimal technical outlay enables.
- the molding machine according to the invention is characterized by a number of significant benefits.
- the spacer element which in a gap between engages adjacent mold boxes, it is possible to mold boxes using a single transport device, which, seen in the direction of transport, is arranged in front of the molding machine to move. It no additional means of transport are required, to fill the filled mold boxes from the molding machine remove. This results in a much simpler one Construction of both the molding machine and the overall system.
- the spacer has a length of two molded boxes having. No interference occurs due to this length dimensioning the pitch of the individual mold boxes, so that a undisturbed processing in an entire casting plant can.
- the spacer is preferably in a central, Bearing element arranged in the area of the center column.
- Either the spacer element or the bearing element can be used be designed so that it is in the transport path the mold boxes can be introduced, for example by means of a Swivel lever. This ensures that when an empty molding box is pushed in, it is trouble-free can be introduced into the molding machine.
- spacer elements can be provided be, for example, it is possible to parallel to each other Use spacer bars.
- the molding machine comprises a designated 18 Frame, which has four vertical columns as well has two upper and two lower side members.
- Centric a vertical center column 2 is arranged in the frame 18, on which a turntable 3 is rotatable at the lower area and a swivel frame 6 is rotatably mounted on the upper area are.
- the turntable 3 is cycled by means of a drive 4 rotatable by 180 °, a drive 7 is used for clockwise Rotation of the swivel frame 6 also by 180 °.
- a sand dosing device 16 is arranged in the area of the frame 18, a compression unit is located opposite this 17.
- the sand dosing device 16 and the compression unit 17 are only shown schematically, since they are known from the prior art.
- I further shows a compressed air tank 19, which is assigned to the compression unit 17 is.
- the sand dosing device 16 forms a main component of one Sand filling station A, while the compression unit 17th The main component of a compression station B (see Fig. I and II).
- the lifting tables are 1a, 1b and the compression unit 17 can be actuated hydraulically.
- Fig. I extends through the molding machine a transport path 20 on which, as by the Shown arrow, individual mold boxes 10 can be transported are.
- the drive of the transport track 20 is not shown, it is located on the inlet side of the molding machine.
- the swivel frame 6 serves to the filling frames 8a and 8b to accommodate and each by 180 ° to pivot.
- support cams 9a, 9b are provided, which by means of a drive (see FIG. III) and are retractable.
- the support cams are withdrawn 9 the respective filling frame 8 is released, so that this, as shown in the left half of Fig. II, can be placed on a molding box 10a, which again rests on a model plate 5a.
- the Lifting table 1a is now possible from the filling frame 8a, the molding box 10a and the model plate 5a existing Lift off the unit and into the area of the sand dosing device Bring 16. After filling, it is lowered to the state shown in Fig. II, which enables that the turntable 3 pivots this unit by 180 °.
- the mold boxes 10 are fed, as already mentioned, by means of the transport track 20.
- roller conveyor elements 11 provided, which for example by means of a Hydraulic cylinder 12 can be advanced or retracted are a vertical movement in the retracted state to enable the mold boxes 10.
- a spacer element 13 can be swiveled in be, which by means of a bearing element 14 on the frame 18 is stored.
- the bearing element 14 is in turn on a pivot lever 21 is attached, which about an axis 22nd is pivotable by means of a hydraulic cylinder 15 (see FIG. Fig. III).
- FIG. II shows a state in which in the sand filling station A a molding box 10a is arranged on which a filling frame 8a is placed. Both are on one Model plate 5a. It was already using the sand dosing device 16 sand filled in, then the lifting table 1a move to its lower end position while the Roller conveyor elements 11a were advanced so that when an empty molding box 10 into the next transport step Molding machine can be inserted.
- the Transport device By feeding the not shown Transport device is the next molding box 10 on the Transport conveyor 20 pushed into the sand filling station A, wherein at the same time by means of the spacer 13 the finished Molding box 10b is pushed out of the molding machine.
- the rotary table 3 rotates through 180 ° Model plate 5b from the compression station B into the sand filling station A and at the same time the combination of model plate 5a, molding box 10a and filling frame 8a from the sand filling station A to be transferred to compression station B.
- the swivel frame 6 rotates through 180 ° to transfer the filling frame 8b into the sand filling station A.
- the lifting table 1a moves up, takes over the model plate 5b and the molding box 10 and the filling frame 8b and lifts this under the sand machine 16, so that the required The amount of molding sand can be filled.
- the roller conveyor elements 11a and the support cams 9b drive the roller conveyor elements 11a and the support cams 9b back so that the lifting table 1a the model plate 5b, the molding box 10 and the filling frame 8b on the turntable 3 can lower.
- the spacer element 13 moves in its starting position by means of the hydraulic drive 23 back.
- the lifting table 1b moves up to the model plate 5a, the molding box 10a and the filling frame 8a below to raise the compression unit 17 so that the molding sand can be compressed.
- the compaction process Support cams 9 and the roller conveyor elements 11 before, so that when lowering the filling frame 8 on the cams 9 and Molding box 10 remains on the roller conveyor elements 11.
- the model plate 5a is in turn lowered onto the turntable 3. A next work cycle can then be carried out will.
