Abstract: A temperature adjustment device and a temperature adjustment method for a preform in a blow molding device with which it is possible to reduce a molding cycle time is provided. A temperature adjustment device for a preform in which a hollow rod member is inserted into an injection-molded, bottomed preform retained by a retention member, and a first air circulation path is formed between the preform and the hollow rod member to adjust the temperature of the preform. The temperature adjustment device is characterized in that a flow path adjustment member is fitted and attached to the outer periphery of the hollow rod member, whereby the cross-sectional area of the first air circulation path is partially adjusted and changed.

Abstract: A male element (100) of a mould (10) for the compression moulding of a parison comprises: a die (110), extending along a longitudinal axis (A) and including a body (112) having, inside it, a longitudinal cavity (113) 5 extending along the longitudinal axis (A) and, at one end of it, a socket (111) in communication with the longitudinal cavity (113); a stretching rod (120), slidably inserted in the longitudinal cavity (113) and including a terminal portion (121) at one end of it, the stretching rod (120) being movable relative to the die (110) between a retracted position, in which the 10 terminal portion (121) is housed inside the socket (111), and an extracted position, in which the terminal portion (121) is extracted from the socket (111).
