LIQUID BLOW MOLDING APPARATUS AND LIQUID BLOW MOLDING METHOD

摘要

PROBLEM TO BE SOLVED: To propose a liquid blow molding apparatus and a liquid blow molding method which prevent the partial lowering of temperature of a preform or prevent displacement relative to a blow molding mold and suppress the occurrence of molding failure in liquid blow molding.SOLUTION: There is provided a liquid blow molding apparatus 11 in which a support pin 5 is arranged inside a blow molding mold, the support pin 5 comprises a head 6 and a shaft 7, wherein the support pin 5 is configured so that a clearance C between the head 6 and a bottom part P4 of a preform P is formed in a state where the preform P is set in the blow molding mold and configured to be lowered according to the deformation of the preform P by supporting a bottom part P4 of the preform P at the timing during the molding process.SELECTED DRAWING: Figure 1
