Abstract
The present invention is directed to a process for the manufacture of a blow molded container comprising a physical geometry that creates more than one undercut and a means for removal of said container from a mold used to form said container.
Claims6
A process for the manufacture of an extrusion blow molded container with a recessed neck comprising the steps of:
- a) extruding a parison from a die;
- b) mold set in an open position with movable inserts in molding and pinching position;
- c) mold moving to capture the parison;
- d) mold engaging of blow air mechanism;
- e) mold holding until end of blow air cycle;
- f) first phase actuation of movable inserts providing clearance for subsequent phase(s) motions;
- g) subsequent phase(s) movable inserts actuation(s), finally providing a clearance for a container's undercut features to be removed from mold wherein a physical geometry creates more than one undercut;
- h) opening of mold for part removal;
- i) movement of inserts to return to a molding and pinching position;
- j) re-starting of a cycle,
- wherein at least one actuation is in a motion of rotating, curved, elliptical, multi-axis and mixtures thereof.
A process for the manufacture of an injection blow molded container with a recessed neck comprising the steps of:
- a) mold set in an open position with movable inserts in molding position;
- b) transferring a preform into a blow molding mold;
- c) closing the blow mold
- d) engaging of blow air;
- e) holding until end of blow air cycle;
- f) first phase actuation of movable inserts providing clearance for subsequent phase(s) motions;
- g) subsequent phase(s) movable inserts actuation(s), finally providing clearance for container's undercut details to be removed from mold wherein a physical geometry creates more than one undercut;
- h) opening of mold for part removal;
- i) movinginserts to return to molding position;
- j) re-starting of a cycle
- wherein at least one actuation is in a motion of rotating, curved, elliptical, multi-axis and mixtures thereof.
A process for the manufacture of an injection stretch blow molded container with a recessed neck comprising the steps of:
- a) mold set in an open position with movable inserts in molding position;
- b) transferring a preform into a blow molding mold;
- c) close mold;
- d) engaging of a stretch rod and blow air;
- e) holding until end of blow air cycle;
- f) first phase actuation of movable inserts providing clearance for subsequent phase(s) motions;
- g) subsequent phase(s) movable inserts actuation(s), finally providing clearance for container's undercut details to be removed from mold wherein a physical geometry creates more than one undercut;
- h) opening of mold for part removal;
- i) moving inserts to return to molding position;
- j) re-starting of a cycle
- wherein at least one actuation is in a motion of rotating, curved, elliptical, multi-axis and mixtures thereof.
