A blow molding tool (1) for a blow molding machine (1). The blow molding tool (1) comprises at least one first blow mold half (2) and one second blow mold half (3). The first blow mold half (2) has a baseplate (4) and a molding body (5). At least one mold cavity (6) with an inner wall (51) is arranged in the molding body (5). At least one region (511) of the inner wall (51) of the mold cavity (6) comprises, in the associated section of the molding body (5), separate temperature control channels (54) for controlling the temperature of the region (54).

Mold base including a base wall and a peripheral side wall which is connected to the base wall by a fillet, this mould base ending with a peripheral upper edge and including ribs forming cavities for grooves for strengthening the base of a container to be formed and which each straddle the fillet, this mould base also including decompression vents hollowed out of the moulding face and which include, for each rib, at least one pair of shallow side channels which extend on either side of the rib and open, at an upper end, on to the peripheral upper edge.

A mold for manufacturing, by extrusion blow-molding, containing two parts having at least a first section having a first molding surface having a plurality of contact regions configured to simultaneously form, by pressing, regions for fixing at least one internal component to the inside of a parison, and a second section having a second molding surface. The second section of the part of the mold is movable with respect to the at least one first section associated with the part of the mold.

A one-piece mold element (3, 7) for a mold (1) for manufacturing containers from blanks of plastic material by blow molding or stretch blow molding. The mold element (3, 7) includes a one-piece molding wall (4, 8) having a raised molding surface (5, 9) bearing the imprint of at least one portion of a container, the molding wall (4, 8) having at least one decompression vent (20) extending therethrough, the hole leading, via an inner opening (21), onto the molding surface (9), which is provided in the form of a slot.

Even when the filling speed increases, the surface temperature of a molded bottle falls within a constant range, and a sterilizer adequately sterilizes the bottle. A preform is heated, the heated preform is sealed in a mold, the preform sealed in the mold is blow-molded into a bottle, the surface temperatures of a neck portion, a body portion, and a bottom portion of the molded bottle are measured, and the mold temperatures of a neck portion, a body portion, and a bottom portion of the mold is so adjusted that the measured surface temperature of the bottle falls within a specified temperature range.

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.

A one-piece mold bottom (7) for a mold (1) for manufacturing containers, includes a molding wall (8) having a raised molding surface (9) bearing the imprint of at least one portion of a container bottom. The mold bottom (7) includes a cavity (27) integrally formed with the mold bottom (7), defined by a surface casing (29) defined entirely by the mold bottom (7) and including an inner surface (31) of the molding wall (8), opposite the molding surface (9) and matching the raised pattern thereof, and a rear surface (32, 33) opposite the inner surface (31). The mold bottom (7) is provided with at least one pair of openings (35; 37) leading into the cavity (27) for circulating a heat-transfer fluid inside the cavity.

The invention relates to a blow molding tool for a blow molding machine for producing plastic containers in an extrusion or stretch blow-molding process. The blow molding tool comprises two blow mold halves, each of which comprises at least one molding body in which at least one mold cavity is disposed, and a baseplate that receives said molding body. An insulation block consisting of a thermally insulating material is arranged between the molding body and the baseplate and, optionally, further components of the blow mold halves.

Apparatus for transforming plastic parisons into plastic containers includes a transforming station having a blow mould within which plastic parisons can be expanded by application of a gaseous medium. The blow mould has a base part arranged releasably on a support. The transforming station has at least one first connector for supplying a flowable temperature control medium to the transforming station, and this supply of the temperature control medium can be disconnected via the connector. The fastening mechanism has a release element which is movable in a predetermined straight direction. By displacement of this release element into a first predetermined position fastening of the base part on the support is releasable and by a displacement of this release element into a second predetermined position the base part can be fastened on the support.
