Abstract
The invention relates to a device for production of dental molded parts from a polymerizable plastic, with a flask (16) and with a heating device (40) for heating the polymerizable plastic in the flask (16). The heating device (40) is movable relative to the flask (16).
Claims26
A device for production of dental molded parts from a polymerizable plastic, the device comprising:
- a flask (16);
- a heating device (40) for heating the polymerizable plastic in the flask (16);
- a receiving area (41) for the flask (16), wherein the heating device (40) and the flask (16) are movable relative to one another between a rest position and a heating position, and wherein the heating device (40) heats the flask (16) in the heating position;
- wherein the flask (16) has two flask shells which can be pressed onto one another with aid of a clamping device (20), and wherein the two flask shells can be held together with aid of at least one mechanical closure element;
- and
- wherein the clamping device (20) has two clamping levers (22) which, each with a clamping jaw (28), press the two flask shells onto one another and jointly interact with a clamp element.
