ABSTRACT:
A blow-molding machine comprises a plastics extruder having a horizontal barrel which is mounted to swing in a horizontal plane about a vertical axis at or close to the center line of the extruder hopper, whereby the downwardly directed extrusion nozzle at the end of the barrel may be smoothly swung between an extruding station and a molding station horizontally spaced from the extruding station. A vertical blow pin, mounted to be moved horizontally between the molding station and a discharging station, moves the extrusion nozzle therewith so that when the blow pin is moved from the molding station to the discharging station, the continuously extruding parison is transported between the halves of a split blow mold at the molding station. Means are provided for severing the parison from the parent plastics material, whereafter the extrusion nozzle is restored to the extruding station and the blow pin is moved to the molding station and inserted into the parison to compression mold the neck portion of the article and effect the blow molding of the article. When the blown article has cooled sufficiently, the mold-halves are opened, the article is transported on the blow pin to the discharging station where it is deposited in an upright position on a take-off platform, subsequent closure of the mold halves closing trimming plates to trim excess plastics material from the hollow article. In a modified embodiment, the production rate is increased by providing the machine with two molding stations at opposite sides of the extruding station.
