Abstract
An extension rod sliding mechanism includes an extension rod that outputs a fluid, which extends an intermediate molding product through blow molding, from a tip part; an extension plate that is joined to the extension rod and that moves in an axial direction of the extension rod; a blow core portion in which a through-hole for guiding the extension rod that moves in the axial direction with a movement of the extension plate is formed; and a guide member that penetrates the extension plate in the axial direction of the extension rod and that guides the extension plate moving in the axial direction of the extension rod.

An extension rod sliding mechanism comprising:
- an extension rod that outputs a fluid, which extends an intermediate molding product through blow molding, from a tip part;
- an extension plate that is joined to the extension rod and that moves in an axial direction of the extension rod;
- a blow core portion in which a through-hole for guiding the extension rod that moves in the axial direction with a movement of the extension plate is formed;
- and
- a guide member that penetrates the extension plate in the axial direction of the extension rod and that guides the extension plate moving in the axial direction of the extension rod.
An intermediate mold comprising:
- an extension rod sliding mechanism,
- wherein the extension rod sliding mechanism includes
- an extension rod that outputs a fluid, which extends an intermediate molding product through blow molding, from a tip part,
- an extension plate that is joined to the extension rod and that moves in an axial direction of the extension rod,
- a blow core portion in which a through-hole for guiding the extension rod that moves in the axial direction with a movement of the extension plate is formed, and
- a guide member that penetrates the extension plate in the axial direction of the extension rod and that guides the extension plate moving in the axial direction of the extension rod.
A mold unit comprising:
- a stationary side mold;
- an intermediate mold that includes an extension rod sliding mechanism;
- and
- a movable side mold,
- wherein the extension rod sliding mechanism of the intermediate mold includes
- an extension rod that outputs a fluid, which extends an intermediate molding product through blow molding, from a tip part,
- an extension plate that is joined to the extension rod and that moves in an axial direction of the extension rod,
- a blow core portion in which a through-hole for guiding the extension rod that moves in the axial direction with a movement of the extension plate is formed, and
- a guide member that penetrates the extension plate in the axial direction of the extension rod and that guides the extension plate moving in the axial direction of the extension rod.
