Device for forming bracket on hollow body

Abstract

Abstract PURPOSE:To form a bracket at an arbitrary position of a hollow body at any angle by a method wherein a part of a parison is pinched with a pair of chucking bodies connected to arm bodies, which are connected to each other so as to be pivotable and openable and closable and open and close at the forward and backward movements to a cavity, so as to be pivotable in the same plane as that of the arm bodies. CONSTITUTION:Together with the advancement of pinchers 11 to the cavity 7 of a blow mold 5, in which a parison 22 is housed, a pair of the arm bodies 13 of the pinchers 11 is opened by pivoting toward the cavity 7. Next, a part of the parison 22 is pinched with a pair of chucking bodies 17, which is pivotably supported at the tip parts of both the arm bodies 13, through the closing of their, tip sides by pivoting. At this time, since a pair of the arm bodies is open, a pair of the chucking bodies 17 pinches a part of the parison so as to pick with the fingers. Next, together with the retreat of the pinchers 11 from the cavity 7, a pair of the arm bodies 13 closes by pivoting. With the closing of a pair of the arm bodies, a pair of the chucking bodies 17 also pivots, resulting in bringing the whole pinchers into a closed state. As a result, a part of the parison pinched between said chucking bodies 17 is pressed so as to form a bracket 23 part.
