Abstract
An injection blow molding apparatus comprises: a first oil supply section which has a hydraulic drive source composed of a drive motor, whose number of revolutions can be controlled, and a hydraulic pump and which supplies oil from an oil tank to an injection mold drive unit provided in an injection mold unit; and a second oil supply section which has a hydraulic drive source composed of a drive motor, whose number of revolutions can be controlled, and a hydraulic pump and which supplies oil from the oil tank to a blow mold drive unit provided in a blow mold unit, the second oil supply section being provided independently of the first oil supply section.
Claims6
An injection blow molding apparatus, comprising:
- an injection molding section configured to form a preform by injection molding, the injection molding section including:
- an injection unit;
- and
- an injection mold unit configured to be operated by an oil pressure;
- a blow molding section configured to blow mold the preform and including a blow mold unit;
- a first oil supply section including a hydraulic drive source and configured to supply oil from an oil tank to an injection mold drive unit of the injection mold unit, the hydraulic drive source including:
- a drive motor, whose number of revolutions is configured to be controlled;
- and a hydraulic pump;
- a third oil supply section including a hydraulic drive source and configured to supply oil from the oil tank to an injection drive unit of the injection unit, the hydraulic drive source including:
- a drive motor, whose number of revolutions is configured to be controlled;
- and a hydraulic pump;
- and
- a controller configured to control the number of revolutions of the drive motor of the first oil supply section,
- wherein the injection mold drive unit includes at least an opening/closing drive portion for opening and closing the injection mold,
- wherein the first oil supply section is configured to supply oil from the oil tank to the opening/closing drive portion,
- wherein the third oil supply section is provided independently of the first oil supply section, and
- wherein the controller, which is configured to control the number of revolutions of the drive motor of the first oil supply section, is configured to control the number of revolutions of the drive motor of the third oil supply section.
