Abstract
A method for the production of a hollow body from die casting aluminum in a die casting machine with a die casting die having mould parts with a stationary mould part and with at least two movable mould parts. The movable mould parts are guided in at least one further movable mould part of the die, so that, in the closed position of the die, the movable mould parts are blocked at least by way of an interlock which is attached to the stationary mould part.
Claims9
A method of producing a hollow body from die cast aluminium, the method comprising:
- providing a die casting machine with a casting die that includes a stationary mould plate and a movable mould plate having a plurality of movable mould parts which correspond to an outer contour of the hollow body to be cast and which are movable from a centre of the movable mould plate, the movable mould parts being guided in at least one additional second movable mould part of the die, the movable mould parts combining with corner battens to form a space in which a third movable mould part is introduced;
- moving the movable mould parts and the corner battens together;
- forming a seal which is of at least single-stage form, such that in a closed position of the die, the movable mould parts are blocked at least by interlocks which are attached to the stationary mould plate.
A method of producing a hollow body, the method comprising:
- providing a die casting machine with a mould that includes a stationary mould plate and movable mould plate having a plurality of movable mould parts which are movable from a centre of the movable mould plate;
- moving a core into the mould, the core having a plurality of teeth on an outer surface thereof which form corresponding casting points on an inner surface of the hollow body;
- displacing the movable mould parts from the centre of the movable mould plate and closing the mould by pressing the movable mould plate against the stationary mould plate;
- pressing a liquid metal into the mould;
- moving the movable mould plate into an operating position and then moving the core to the operating position;
- and
- removing the hollow body from the mould after moving the core to the operating position.
