Embodiment Construction

[0063] figure 1 is a rough structural representation of an apparatus 1 for forming plastics material pre-forms 10 into plastics material containers 20 according to the invention. The heated plastics material pre-forms 10 are supplied to the apparatus by means of a heating device 50; wherein the heating device 50 may be, for example, a microwave oven or an infrared heating oven. Reference numeral 6 refers to a blow molding device, inside which the plastics material preforms are expanded by the action of air to form plastic containers. Reference 4 refers to a single forming station. It is worth noting that the device 1 has a carrier 2 on the outer edge of which a plurality of forming stations 4 are arranged. Reference numeral 20 designates the finished container.

[0064] figure 2 Curve K1 is shown, which illustrates the movement of the rod. In this example, the position of the rod is plotted on the left coordinate and the pressure is plotted on the right coordinate. Time...

Abstract

An apparatus for forming plastics material preforms into plastics material containers, the apparatus having a movable carrier on which at least one forming station for forming plastics material preforms into plastics material containers is provided; the forming station has an internal forming cavity The blow molding device, the plastic material preform is formed into a plastic material container in the cavity; the forming station also has a pressurizing device that acts on the plastic material preform through a flowable medium to expand the plastic material preform, and can insert the plastic material preform A rod-shaped body for stretching the plastics material pre-form in the longitudinal direction, and a drive device for moving the rod-shaped body relative to the plastics material pre-form. According to the invention, a coupling device is provided which couples the movement of the rod-shaped body relative to the plastics material pre-form, in particular mechanically, at least for a period of time, with the movement of the pressing device relative to the plastics material pre-form; the device has at least partially Influencing means for influencing the feed movement of the pressing means to the plastics material pre-forms.

Description

technical field [0001] The invention relates to a device and a method for forming plastics material preforms into plastics material containers. Background technique [0002] Devices and methods of this type already exist in the prior art. In this case, the plastics material pre-form is usually first heated in a heating furnace and then shaped into a container by a forming device, in particular a blow molding machine. For this purpose, a gaseous medium, in particular a blast, is usually used to act on the plastics material pre-form, which is then further stretched by the rod-shaped body. [0003] In this case, the plastics material pre-form is usually expanded by means of a blow molding nozzle which is introduced into the plastics material pre-form. In this case, it is known that the blow molding nozzle is fixed on the blow molding piston, and it is known that the blow molding nozzle or the blow molding piston can be provided to the plastics material pre-forms using a guide...
