A blow-molding machine for producing blow-molded hollow bodies from a thermoplastic material, includes two blow-mold halves which can be horizontally displaced and provided with separate drive units for a transport drive and for the sequence of movements of the mold closing and locking device to open and close the blow mold halves. Conventional blow-molding machines are still equipped with hydraulic drives at least for the mold closing and locking device. In order to provide a blow-molding machine that can for example be operated under clean-room conditions, the drive unit of the blow-molding machine according to the invention is configured for the clamping elements of the mold closing and locking device as an electromotive direct drive with a spindle drive and a spindle mechanism with recirculating rollers.

Blow molding machine

The invention relates to an extrusion head for producing a tubular parison ( ) 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 ( ) in order to alter the wall thickness of the exiting parison ( ). 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 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 ( ) in the mandrel gap ( ) from inside and/or outside, whereby at least two of the adjustment elements (D 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.

Extrusion head

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.

The invention relates to a storage head for a blow moulding machine for discontinuous manufacture of multi-layer co-extruded and blow-moulded hollow bodies made of thermoplastic. To improve the product quality and to increase the throughput, each distributor element is designed as a spiral channel distributor (20) which distributes the individual molten plastic streams uniformly at the periphery. The ejector (14) consists of at least two concentric tubular pieces (42, 44) and the peripherally distributed plastic flows from the ejector (14) through an annular gap (46) into the storage space (16) in the storage head housing (10) below the ejector.

Storage head for a blow molding machine

A mold closing system for plastic fabricating machines, having a separate transport means for carrying the mold halves toward and away from one another, and separate locking means mounted on the mold halves and operable at the end of the transport movement to lock the mold halves together after the transport means is shut off.
