PARISON THICKNESS DEVIATION ADJUSTMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To suppress initial equipment cost and running cost in a parison thickness deviation adjustment device.SOLUTION: A parison thickness deviation adjustment device 10 comprises: a first movement adjustment member 11 and a second movement adjustment member 12 for respectively moving a die 3 to a first axis P1 and a second axis P2 direction, being orthogonal to a center axis P of a core 2; a first servo motor 21 and a second servo motor 22 for respectively moving and adjusting the first movement adjustment member 11 and the second movement adjustment member 12 along the first axis P1 and the second axis P2 directions; a first pressing member 31 and a second pressing member 32 disposed so as to face the first movement adjustment member 11 and the second movement adjustment member 12 respectively sandwiching the center axis P of the core 2, and pressing the die 3 to the center axis P of the core 2; and a first air cylinder 41 and a second air cylinder 42 for switching a pressing state and a pressing release state of the first pressing member 31 and the second pressing member 32.SELECTED DRAWING: Figure 1
