Layered slab manufacturing system and method

A manufacturing method uses layered slabs to create a final pattern for a mold or for creating the mold itself. The method includes: preparing a desired number of slabs including a first slab and a second slab; machining the first slab; machining the second slab; and after the second slab is coupled to the first slab, repeating the machining step for each additional slab included in the desired number of slabs to form the final pattern or mold.

Stackable core system for producing cast plate heat exchanger

A method of forming a cast heat exchanger plate includes forming at least one hot core plate defining internal features of a one piece heat exchanger plate and at least one first set of interlocking features. At least one cold core plate is formed defining external features of the heat exchanger plate and at least one second set of interlocking features. A core assembly is assembled where each hot core plate is directly interlocked to at least one cold core plate. A wax pattern is formed with the core assembly with an external shell formed over the wax pattern. The wax pattern is removed to form a space between the core assembly and the external shell. The space is filled with a molten material. Once the molten material has solidified, the external shell and the core are removed.

A method including: obtaining a part design file of a part; deriving, from the art design file, a central mold design; determining one or more fill points for the central mold design; and attaching one or more mating connectors to the determined one or more fill points to create a modular part mold file.

DIE MOLDING SURFACE TREATMENT DEVICE

When molding surfaces (50A) of a pair of dies (50) are to be cleaned by air-blowing, air is blown towards the molding surfaces (50A) from blowing nozzles (22A) of a cleaning blowing function portion (22) while a moving body (16) is reciprocatingly moved by driving force of a driving mechanism (18). When a parting agent is to be applied to the molding surfaces (50A) of the pair of dies (50), the mold release agent is jetted out towards the molding surfaces (50A) from spraying nozzles (24A) of a parting agent application function portion (24) while the moving body (16) is reciprocatingly moved by the driving force of the driving mechanism (18). In both of these situations, at the same time as the treatment of the molding surfaces (50A), a cleaning brush (32) reciprocatingly moves together with the moving body (16) and sweeps a device floor surface (12).
