Abstract
A blow molding apparatus includes: a temperature adjusting unit configured to supply a preform with cooling air to perform a temperature adjustment of the preform, the preform having been injection-molded, having a bottomed shape and made of a resin; a blow molding unit configured to blow-mold the preform that has been subjected to a temperature adjustment with blow air, and configured to manufacture a container made of a resin; an air tank configured to supply the temperature adjusting unit with the cooling air; and a recovery unit configured to recover the blow air exhausted from the blow molding unit into the air tank.
Claims10
A blow molding apparatus comprising:
- a temperature adjusting unit having a first mold that accommodates a preform and configured to perform a cooling blow that supplies cooling air to the preform in the first mold in order to adjust a temperature of the preform, the preform having been injection-molded, having a bottomed shape and made of a resin;
- a blow molding unit having a second mold different from the first mold and that accommodates the preform, configured to blow-mold the preform that has been subjected to a temperature adjustment with blow air in the second mold, and configured to manufacture a container made of a resin;
- an air tank configured to supply the temperature adjusting unit with the cooling air;
- and
- a recovery unit configured to recover the blow air exhausted from the blow molding unit into the air tank.
A blow molding method comprising:
- accommodating a preform in a first mold to perform a cooling blow that supplies cooling air to the preform in the first mold in order to adjust a temperature of the preform, the preform having been injection-molded, having a bottomed shape and made of a resin;
- accommodating the preform in a second mold different from the first mold to blow-mold the preform that has been subjected to the temperature adjustment with blow air in the second mold, to manufacture a container made of a resin;
- and
- recovering the blow air exhausted in the blow-molding into an air tank from which the cooling air is supplied.
