    摘要: The invention relates to an extrusion head (10) for a blow molding machine for producing two-layered hollow plastic bodies, including one or more extruders, connected to the extrusion head housing (12), for supply of molten plastic melt. In particular when using different plastic materials of different viscosities, it is very important to create for both materials substantially the same rheological flow conditions when distributed across the circumference to form a tubular parison. This is attained in accordance with the invention by making the ejector piston of two concentric cylindrical sleeves which define between them an annular gap in which the two spiral-channel distributor elements are located in opposite disposition inside on the inner surface of the outer cylindrical sleeve and outside on the outer surface of the inner cylindrical sleeve, so that the circumferentially distributed plastic materials of both distributor elements exit at the lower end of the annular gap approximately centrally from the ejector piston into the storage space of the extrusion head.

    摘要: The invention relates to an extrusion storage head (10) for a blow-molding machine and a method for production of blow-molded multi-layer plastic hollow bodies made from a two- or multi-layer pre-form, whereby two or more peripheral manifolds (16, 18) are arranged above a storage reservoir (20), from which the peripherally-extruded plastic may be sequentially ejected as a tubular parison from a controlled annular nozzle (24) by means of an ejector piston (22). According to the invention, an additional peripheral manifold (26) is arranged between the storage chamber (20) and the controlled annular nozzle (24) for application of a further plastic layer (outer functional layer) on the previously peripherally extruded plastic carrier. The additional peripheral manifold (26) is connected through a supply line (28) to an additional external storage element (30) for the molten plastic of the functional layer, wherein the additional external storage element (30) has a separate extruder (32).

    摘要: A blow molding machine, includes a base frame, a blow mold adapted for receiving a tubular parison and having a first mold support plate for support one mold half and a second mold support plate for support of another mold half. A transport unit is mounted to the base frame for so moving the first and second support plates that the mold halves are free from any direct, form-fitting coupling, with the transport unit including a first drive mechanism operatively connected to the first support plate and a second drive mechanism operatively connected to the second support plate and operating independent of the first drive mechanism. Secured to the support plates is a locking mechanism for pinching off the tubular parison and clamping the mold halves during the blow molding operation.

    摘要: The invention relates to an extrusion head for producing a tubular parison (22) in order to manufacture large-volume, blow molded plastic hollow bodies. The inventive extrusion head has an adjustable ring-shaped tube outlet nozzle for selectively adjusting the nozzle opening (20) in order to alter the wall thickness of the exiting parison (22). In order to provide a multiple adjustability of the extruded tube cross section, the invention provides that the extrusion head comprises at least three separate nozzle/mandrel gap adjustment elements (D 0=mandrel, DS I, DS II, DS III) which are differently profiled and exchangeable. The elements can be individually and/or simultaneously brought into working contact with the exiting parison (22) in the mandrel gap (20) from inside and/or outside, whereby at least two of the adjustment elements (D 0=mandrel, DS I, DS II, DS III) are configured such that they can be adjusted. To this end, the at least two adjustment elements are each equipped with a corresponding adjusting drive.
