Abstract
The invention relates to a device for producing containers (22) by blow molding, with at least one temperature-controllable blow mold (21) held by a mold holder (20), namely with a bottom insert held by a bottom mold carrier and/or with mold inserts held by mold half carriers, and is characterized by an inductive heating device, which indirectly heats the bottom insert and/or the mold inserts by means of induction.
Claims20
A device for producing containers by blow molding comprising:
- at least one temperature-controllable blow mold held by a mold holder, wherein the blow mold and the mold holder include a bottom mold insert held by a bottom mold carrier and/or mold half inserts held by mold half carriers;
- and
- an inductive heating device;
- wherein the mold holder includes a plurality of inductors, which are arranged at a distance to each other, as the inductive heating device,
- wherein the plurality of inductors are arranged in a matrix with two or more inductors in a circumferential direction and two or more inductors in a longitudinal direction of the mold holder,
- wherein the mold holder and/or the blow mold is/are provided with a plurality of adapters, which are arranged at a distance to each other and are configured to be directly heated by means of induction by the plurality of inductors,
- wherein the bottom mold insert held by the bottom mold carrier and/or the mold half inserts held by the mold half carriers is/are configured to be indirectly heated by means of induction via heat transferred from the plurality of adapters, which are configured to be directly heated by means of induction by the plurality of inductors, and
- wherein the device is a blowing station of a blowing machine arranged on a rotary driven blowing wheel.
