Abstract
A temperature adjustment mold for adjusting a temperature of an injection-molded bottomed preform made of resin includes: an air introduction member that is inserted into the preform and cools the preform by introducing compressed air from an air supply port into an interior of the preform; a cavity mold that accommodates the preform inside and performs heat exchange in contact with an outer peripheral surface of the preform into which the compressed air has been introduced; and a heating mechanism that heats a first portion of the cavity mold facing the air supply port more than a second portion of the cavity mold located on a downstream side of a flow path of the compressed air than the first portion.
