Publication number: 20240123671Abstract: A temperature adjustment mold capable of performing local temperature adjustment in an axial direction from the inside of a preform while restricting shrinkage and deformation of the preform, for adjusting a temperature of an injection-molded bottomed resin-made preform includes a rod portion inserted into the preform and extending in the axial direction of the preform. The rod portion includes an annular projection portion that protrudes in a radial direction of the rod portion and contacts an inner peripheral surface of the preform. The rod portion contacts a bottom portion of the preform to restrict shrinkage in the axial direction of the preform. The projection portion restricts shrinkage in a radial direction of the preform, conducts heat between the rod portion and the preform, and adjusts a temperature at a predetermined part in an axial direction of the preform.Type: ApplicationFiled: February 22, 2022Publication date: April 18, 2024Applicant: NISSEI ASB MACHINE CO., LTD.Inventors: Kiyonori SHIMADA, Tomomi TSUCHIYA, Koichi IKEDA, Yuya MIYASAKA
