Abstract

A die casting machine with a die casting mold produces metal die cast parts. The die casting machine has a first machine shield, to which a first mold half of the die casting mold is secured, and a second machine shield, to which a second mold half of the die casting mold is secured. In order to compensate for the deflection of the machine shields, an intermediate plate which has at least two temperature-controlling devices that can be used to generate a temperature difference leading to the curving of the intermediate plate is arranged between the first machine shield and the first mold half and/or between the second machine shield and the second mold half.

First claim

What is claimed is:

1. A die casting machine with a die casting mold for producing metal die cast parts, comprising:
a first machine shield, to which a first mold half of the die casting mold is fastened;
a second machine shield, to which a second mold half of the die casting mold is fastened; and
an intermediate plate, which comprises at least two temperature-controlling devices by way of which a temperature difference which results in curvature is generatable, wherein
the intermediate plate is arranged between the first machine shield and the first mold half and/or between the second machine shield and the second mold half.

2. The die casting machine according to claim 1 , wherein
the intermediate plate comprises a first, electrically operable temperature-controlling device and a second temperature-controlling device which is operable with a temperature-controlling medium.

3. The die casting machine according to claim 1 , wherein
the intermediate plate comprises a first temperature-controlling device which is operable with a temperature-controlling medium and a second temperature-controlling device which is operable with a temperature-controlling medium.

4. The die casting machine according to claim 3 , wherein
the two temperature-controlling devices are formed by two differently designed duct systems.

5. The die casting machine according to claim 1 , wherein
the intermediate plate is produced from a solid steel block.

6. The die casting machine according to claim 1 , wherein
the intermediate plate comprises a height of between 250 mm and 350 mm in a closing direction.

7. A method of using a die casting machine having a die casting mold, the die casting machine comprising:
a first machine shield, to which a first mold half of the die casting mold is fastened;
a second machine shield, to which a second mold half of the die casting mold is fastened; and
an intermediate plate, which comprises at least two temperature-controlling devices by way of which a temperature difference which results in curvature is generatable, wherein the method comprises:
arranging the intermediate plate between the first machine shield and the first mold half and/or between the second machine shield and the second mold half; and
producing motor vehicle components via the die casting machine with the intermediate plate.

8. The method according to claim 7 , wherein
the produced motor vehicle components are motor vehicle side members.

9. A method of operating a die casting machine comprising a first machine shield, to which a first mold half of the die casting mold is fastened; a second machine shield, to which a second mold half of the die casting mold is fastened; and an intermediate plate, which comprises at least two temperature-controlling devices by way of which a temperature difference which results in curvature is generatable, the method comprising:
arranging the intermediate plate between the first machine shield and the first mold half and/or between the second machine shield and the second mold half;
setting a temperature difference in the intermediate plate such that the first and second mold halves of the die casting mold properly close.

10. The method according to claim 9 , wherein
the temperature difference is set to be between 30 K and 70 K.

11. The method according to claim 9 , wherein
the temperature difference is set to be 50 K.
