METHOD FOR MANUFACTURING CASTING MOULDS AND CORES USING THE TECHNOLOGY OF MOULDING COLD-HARDENING MIXTURES (CHM) INTO MODEL-CORE EQUIPMENT, THE FORMING MATERIAL OF WHICH CHANGES THE GEOMETRY IN A SHORT TIME Russian patent published in 2023 - IPC B22C9/02 B22C13/02 B22C15/02 B22C19/02 

FIELD: foundry production.

SUBSTANCE: method for manufacturing casting moulds and cores from cold hardening mixtures (CHM) includes 3D modelling of the casting, forming the form-generating surface of the model-core equipment in the form of many segments (2) and moulding CHM into the resulting form-generating surface. Using the specified CHM moulding, components of casting moulds and cores are produced, from which moulds and cores are then assembled. 3D models of these components are formed in a CAD system based on a 3D model of the casting, while an algorithm is entered into the programmable device and control codes are created for the controller, which supplies control signals to the actuators (3) to move the segments (2). The control signal is supplied to the actuator corresponding to the “X” and “Y” coordinates, which moves the segment along the “Z” axis relative to the forming surface. The segment, the height of which is specified technologically, is made in the cross section in the form of a regular triangle, a regular quadrangle or a regular hexagon.

EFFECT: stages of development of design documentation and production of model-rod equipment are eliminated.
