| A mould assembly for producing a casting core for a cooling jacket of an electric motor has an external mould and an internal mould enclosed by the external mould. The external mould forms an outer wall and the internal mould an inner wall of the core moulding cavity fillable with a core material and having a cylindrical shape. The internal mould has two first mould shells and two second mould shells. The two first mould shells and the two second mould shells jointly form the inner wall of the core moulding cavity. The second mould shells are arranged between the first mould shells. A first demoulding mechanism is arranged between the first mould shells and enables movement of the first mould shells toward one another. A second demoulding mechanism is arranged between the second mould shells and enables movement of the second mould shells toward one another. | ||||||

| A furnace assembly for dewaxing investment casting molds includes a housing having a top and a bottom and sides and extends along an axis to define a cavity. A plurality of tiles are supported in a spaced relationship with the bottom of the housing and define a pair of lower chambers for directing the wax vapors out of the cavity. A plurality of trays having apertures are supported by the tiles for moving molds through the housing. Chimneys connect to the lower chambers and a passageway is defined by the tiles for evacuating the wax and wax vapors from the cavity to the lower chambers and out through the chimneys. A pair of lower burners extends into the lower chambers for igniting wax vapors in said lower chambers. The heat from the lower chambers radiantly heats up portions of the furnace assembly that are disposed above the lower chambers. | ||||||

| 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. | ||||||

| 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. | ||||||

| The object of the device is to provide a novel cam device applicable to sand molding machines in which the cam (1) has its active surface (2) facing downwards to prevent sand or dirt from being deposited between said cam (1) and the its supporting follower (10), which the machine is provided with to cause the swivelling of the said cam. For this purpose the cam (1) is hinged at a point (3) to a frame (4) which may move longitudinally, while on another point (5) it is hinged to a connecting rod (6) which is in turn hinged on its opposite end at the point (8) to the front swinging plate (7) of the sand mote molding machine, with said front plate (7) hinged at the point (9) on its rearmost edge to the frame (4). | ||||||

| 31 | Foundry core or mold making machine | US173176 | 1980-07-28 | US4378835A | 1983-04-05 | Gilbert J. Janke |
| A foundry core or mold machine utilizes a horizontally extending frame pivoted at one end which fixedly supports one box half or cope and movably supports the other box half or drag. A power actuator pivots the frame to clamp the box halves closed against a blow head or gassing head which may be shuttled thereabove. The drag box half is mounted on a cradle on the frame for movement toward and away from the cope or fixed box half and for pivoting movement to bring the box to a core or mold discharge or an inspection or disassembly position when the box halves are not clamped against the blow head or gassing head. Each box half includes a machine actuated stripping mechanism to insure removal of the core or mold both from the cope and drag with the latter then placing the core on a discharge conveyor. The conveyor may be of the flat belt type canted slightly to present a flat surface to receive the core or mold. | ||||||

| The present disclosure relates to a system for fabricating a mold positive via additive manufacturing to form a casting mold. The mold positive material may have a first portion that undergoes a solid to gas phase transformation at a first temperature and a second portion that undergoes a solid to gas phase transformation at a second temperature. The first portion may be formed within the second portion, and the first temperature may be low relative to the second temperature. The first portion of the mold positive may thermally decompose at a lower temperature than the second portion, which may create voids within the mold positive so that during the higher temperature combustion of the second portion of the material, the second portion may expand into the newly empty spaces instead of into a ceramic casting mold. This may greatly reduce stress on the casting mold. | ||||||
