摘要:
Machine for the production of sand moulds comprising a machine structure with a moulding chamber (3), a front plate (1) and a rear plate (2). The front plate (2) and rear plate (3) are arranged for pressing sand within said moulding chamber so as to form a sand mould, and are arranged for receiving respective pattern plates (200) for providing front and rear surfaces of the sand mould with corresponding patterns. The machine further comprises a robot arm (6) arranged for replacing the pattern plates (200), said robot arm being (6) attached to the machine structure, such as to a side (101) of the machine structure.
摘要:
The invention relates to a mote molding machine which comprises a molding chamber (3), a front plate (1) closing the molding chamber at a front end and a rear plate (2) closing the molding chamber (3) at a rear end, opposite the front end. The plates shift gradually during the mote compression and extraction phases. The machine comprises a first shifting system for shifting the front plate and which comprises at least one first electric motor (4), and a second shifting system for shifting the rear plate and which comprises at least one second electric motor (5).
摘要:
A mold-forming assembly for forming chemical set sand into a plurality of mold portions for one or more objects to be cast in the mold portions. The assembly includes a loading subassembly for forming the mold portions, a positioning subassembly for positioning each mold portion in a predetermined position, and a conveyor subassembly extending between the loading and positioning subassemblies, for moving the mold portions from the loading subassembly to the positioning subassembly.
摘要:
A device for supporting an upper mold tool (7) for movement with respect to a lower mold tool (25). Compared to known devices with simple pivoting supports, in which the space conditions for handling the workpieces with the mold tool opened are very restricted, the upper mold tool (7) is supported on a frame (1) by means of a multi-bar mechanism, such as a four-bar mechanism (10, 11) or a six-bar mechanism to provide a very wide opening of the space between the two mold tools.
摘要:
A method of making sand molds, cores or the like for use in casting foundry pieces. First and second continuous conveyors are utilized, the first conveyor having a number of pattern pieces and flasks attached to it, and the second conveyor for transporting the sand molds, cores or the like from the flasks after deposition thereon by inverting the flasks over the second conveyor. Each flask is filled in turn with sand and binder mixture when in an upright position, the sand-binder mixture is compacted and partial curing thereof is allowed, the flasks are inverted in turn to bring the sand mold into contact with the second conveyor, and the sand mold is released from each flask while it is inverted. Each flask is then brought back into an upright position for receipt of further sand-binder mixture to repeat the process, the process being substantially continuous.
摘要:
An arrangement is disclosed for improving the handling or stripping of the flasks or molds of the type which are used to cast large items such as cast metal plates or frames. A system is provided for lifting the flask or mold vertically from the pattern with assurance that each portion or part is moved at exactly the same rate and amount as every other part.
