FIELD: extrusion-blow forming of plastic articles. ^ SUBSTANCE: proposed device for making hollow articles from plastic by extrusion-blow forming method contains extrusion block, extruder and die head with one extrusion nozzle connected with extruder. Block is installed in frame of housing. Device has one position with blow moulds provided with table with blow moulds, with one mould having hole made on side of mould pointed to extrusion nozzle. Mould can be moved along side guide from end position at side of die head to position under die head and back to provide vertical overlapping of extrusion nozzle and hole of mould. Die head is installed for vertical tilting and turning to side in housing, and it can be shifted in longitudinal direction. Device is furnished with articulated fastening in zone of center of gravity of extrusion block on end section of extruder pointed from die head for which hinge fastening on drive section is provided. Die head is hinge connected with extruder. ^ EFFECT: reduced cost of manufacture, provision of compensation of vibration of extrusion block correction of positions. ^ 9 cl, 3 dwg |
