Abstract
The invention relates to a device for manufacturing models layer by layer. The inventive device comprises a frame (1), a vertically adjustable and exchangeable workpiece platform (17)m and a device for feeding the material comprising a coating applicator (4). Said coating applicator (4) serves to feed material from a storage container to a process zone above the workpiece platform (17), said workpiece platform (17) being fixed in the device at least during manufacturing of a model. The workpiece platform (17) is introduced on the one side of the device and extracted on the other side of the device.
Claims17
A device for pattern building in layers, comprising
- a frame defining a workspace within the frame;
- a workpiece platform for defining a building area, and being positioned within the frame and being height adjustable during pattern building for building a metal casting mold in layers;
- a storage bin situated in a workspace above the workpiece platform and serving as a source of a feed material including a moulding sand;
- a material feeder for delivering the feed material including the moulding sand from the storage bin to the workpiece platform;
- a feed material spreader including means for balancing out sag of the spreader along its length;
- and
- a dispenser for fluidly spraying a liquid agent to the moulding sand, which is delivered to the workpiece platform, for chemically hardening a resin and moulding sand admixture,
- wherein the building area is essentially rectangular, and has a pair of longer edges and a pair of shorter edges when viewed from the top, and the spreader is arranged to translate along at least one of the shorter edges of the rectangular cross-section of the workpiece platform.
A device for building a metal casting patterns in layers, comprising:
- a frame defining a rectangular workspace within the frame;
- a workpiece platform for defining a building area, which platform is interchangeable with at least one other workpiece platform, being positioned within the frame and being height adjustable during operation for building a metal casting patterns in layers;
- at least one motor for adjusting the height of the workpiece platform during operation;
- a storage bin situated in a workspace above the workpiece platform and serving as a source of a feed material including a moulding sand;
- a material feeder for vibratingly delivering the feed material including the moulding sand from the storage bin to the workpiece platform;
- a steel strip feed material spreader including means for balanced out to prevent sag of the spreader along its length;
- and
- an ink-jet dispenser for spraying an agent to the moulding sand on the workpiece platform, for chemically hardening a resin and moulding sand admixture,
- wherein the building area is essentially rectangular, and has a pair of longer edges and a pair of shorter edges when viewed from the top, and the spreader is arranged to translate along at least one of the shorter edges of the rectangular cross-section of the workpiece platform.
