Method for regulating temperature of bottle mold and bottle mold used therefor

摘要

In order to allow vertical ventilation in a plurality of circumferential locations around the contour surface of a mold in the process of molding and regulate the temperature, the ventilation is carried out using an abutting path formed between the abutting surfaces of inner and outer members forming the contour surface part and its outer peripheral part of the mold, thereby achieving cooling. In this way, various shapes based on the axially changing shape of the contour surface are obtained readily and inexpensively, and temperature control suitable for the axially changing shape of the contour surface is carried out with high cooling effect.
