Abstract
A temperature adjusting unit of a blow molding apparatus includes: a first drive unit configured to drive a core mold, from which the cooling air is supplied, in a first direction; a second drive unit configured to drive a cavity mold that accommodates the preform in a second direction; a first lock portion configured to restrict a movement of the first drive unit in the second direction at a first position where the core mold is inserted into the preform; and a second lock portion configured to restrict a movement of the second drive unit in the first direction at a second position where the preform is accommodated in the cavity mold.
Claims12
A blow molding apparatus comprising:
- an injection molding unit configured to injection-mold a preform having a bottomed shape and made of a resin;
- a temperature adjusting unit configured to perform a temperature adjustment of the preform by supplying the preform that has been released from the injection molding unit with cooling air;
- and
- a blow molding unit configured to blow-mold the preform after the temperature adjustment to manufacture a container made of the resin, wherein
- the temperature adjusting unit includes:
- a first drive unit configured to drive a core mold, from which the cooling air is supplied, in a first direction to insert the core mold into the preform;
- a second drive unit configured to drive a cavity mold that accommodates the preform in a second direction opposite to the first direction to accommodate the preform in the cavity mold;
- a first lock portion configured to restrict a movement of the first drive unit in the second direction at a first position where the core mold is inserted into the preform;
- and
- a second lock portion configured to restrict a movement of the second drive unit in the first direction at a second position where the preform is accommodated in the cavity mold.
A blow molding apparatus comprising:
- an injection molding unit configured to injection-mold a preform having a bottomed shape and made of a resin;
- a temperature adjusting unit configured to perform a temperature adjustment of the preform by supplying the preform that has been released from the injection molding unit with cooling air;
- and
- a blow molding unit configured to blow-mold the preform after the temperature adjustment to manufacture a container made of the resin, wherein
- the temperature adjusting unit includes:
- a first drive unit configured to drive a core mold, from which the cooling air is supplied, in a first direction to insert the core mold into the preform;
- a first stroke changing portion configured to change a movement range of the first drive unit in the first direction;
- a second drive unit configured to drive a cavity mold that accommodates the preform in a second direction opposite to the first direction to accommodate the preform in the cavity mold;
- and
- a second stroke changing portion configured to change a movement range of the second drive unit in the second direction.
A blow molding method comprising:
- injection-molding a preform having a bottomed shape and made of a resin;
- performing a temperature adjustment of the preform by supplying the preform that has been released after injection molding with cooling air;
- and
- blow-molding the preform after the temperature adjustment to manufacture a container made of the resin, wherein
- in the performing the temperature adjustment,
- a core mold, from which the cooling air is supplied, is driven by a first drive unit in a first direction, and the core mold is inserted into the preform,
- a cavity mold that accommodates the preform is driven by a second drive unit in a second direction opposite to the first direction, and the preform is accommodated in the cavity mold,
- a movement of the first drive unit is restricted by a first lock portion in the second direction at a first position where the core mold is inserted into the preform, and
- a movement of the second drive unit is restricted by a second lock portion in the first direction at a second position where the preform is accommodated in the cavity mold.
