Title:
TEMPERATURE REGULATING MOLD AND METHOD FOR PRODUCING RESIN CONTAINER
Document Type and Number:
WIPO Patent Application WO/2023/145775
Kind Code:
A1
Abstract:
This temperature regulating mold for regulating the temperature of an injection-molded resin preform having a bottomed shape comprises: an air introduction member that is inserted into the preform and introduces compressed air from an air supply port to the interior of the preform to cool the preform; a cavity mold that accommodates the preform on the inside thereof, and contacts and undergoes heat exchange with the outer peripheral surface of the preform into which compressed air has been introduced; and a heating mechanism that heats a first site on the cavity mold which faces the air supply port more than a second site on the cavity mold which is downstream from the first site along the flow path of the compressed air.
