ABSTRACT:
A system for manufacturing molded articles and simultaneous engineering of mold cavities, comprising a casting device, a machining device and interchangeable cassettes. The casting device comprises a casting mold having two mold halves, each having cassette receptacles and being moveable against each other perpendicular to a separation surface of the casting mold. The casting device also has interchangeable cassettes inserted into the cassette receptacles of the mold halves so that they abut each other and enclose the mold cavity when the casting mold is closed. The cassettes have positive guides on their sides opposite the separation surface that are insertable into the positive guides on the cassette receptacles of the mold halves. The machining device comprises a machining station such as a drill, a turning tool, a milling tool, a grinder and an eroding tool, and also a clamping device within a working range of the machining station. The clamping device has cassette receptacles with positive guides that correspond to the positive guides of the cassettes. The cassettes can be interchangeably and precisely mounted in the cassette receptacles of the machining device and of the casting device without adjusting the position of the cassettes.
