ABSTRACT:
A machine for producing hollow plastic articles having a housing with a pair of parallel spaced-apart longitudinal guide rails, a stationary extruder head mounted between the parallel guide rails, at least one blow mold closing unit slidably supported on each of the guide rails for supporting a blow mold, an inclinded guide formed on each closing unit defining an inclined path directed toward the extruder head, means for moving each of the units along the guide rails adjacent to the extruder heads and a further means for urging the molds along the inclined path into contact with the extruder at selected time intervals. A controlling unit is also provided so that one, two, three or four molds can be operated in sequence. Means are also provided to open each of the mold halves just prior to the molds contacting the extruder head so that the hollow plastic articles can be removed, trimmed and collected.
