A method for transferring a negative structure of a surface of an inner wall (51) of a blow molding tool (1) onto a surface of a plastic container. The method comprises the steps of heating at least one region (511) of a mold cavity (6) of a molding body (4) of the blow molding tool (1), on which the negative structure is formed, inserting a preform into the mold cavity (6), closing the blow molding tool (1), molding the plastic container by inflating the preform and bringing the preform to lie against the inner wall (51) of the mold cavity (6), cooling the region (511) by supplying a coolant through temperature control channels (54), and removing the plastic container from the mold.

An apparatus for blow-molding plastic containers includes at least one blow-molding station that defines at least one molding cavity for forming plastic containers. The blow-molding station includes two lateral bodies and, for each forming cavity defined by the blow-molding station, a bottom. The bottom includes an external body of the bottom that defines an annular portion that extends around the axis of extension of the respective forming cavity, and an internal body that can be accommodated at least partially inside the annular portion, between the external lateral surface of the internal body and the internal surface of the annular portion there being at least one air evacuation opening that extends around the axis of extension and is connected to first air evacuation elements. The internal body is adjustably movable on command with respect to the annular portion along the axis of extension.

In a fixing member 110 formed with an insertion hole 113 for inserting an elevation rod 111, a communication hole 114 communicating with the insertion hole 113 is formed to open at a side surface of the fixing member 110. A key member 112 is inserted into the communication hole 114 and engaged with a key groove 118 provided at the distal end of the elevation rod 111. By so doing, the elevation rod 111 and the fixing member 110 are coupled together.

The invention relates to a method for producing a plastic article and a blow molding tool for performing the method. The method comprises extruding an approximately tube-shaped preform, dividing the melt flow within the extrusion head or separating the extrudate exiting or already exited from the extrusion head, such that a preform having an approximately C-shaped cross section is obtained, forming the preform into a hollow part within a multipart blow molding tool using differential pressure, wherein an expansion and partial preforming of the preform first takes place with the blow molding tool partially closed, then in a further step at least one insert is inserted into the interior of the partially preformed article between the not completely closed blow molding tool and through the open side of the preform, and in a further step the blow molding tool is completely closed, wherein the article is completely formed, forming at least one at least partially circumferential pinch-off seam.
