Procedure control opening and closing of a blow mold and blowing device arranged for its practice.

摘要

Method for controlling, in a spinning molding carousel moves in a direction (20) of rotation type, the opening and closing of a blow mold mold articulated type for manufacturing thermoplastic containers, particularly PET by blowing or stretch blow parts heated crude, said mold (1) comprising at least two mold halves (2a, 2b) which can be separated from one another by rotation about a common axis (3) fixed articulation asymmetrically on both sides of its plane (5) binding, controlling the two mold halves (2a, 2b) together by two connecting rods (7a, 7b) respective substantially the same length and having first ends coupled rotationally by links (10a, 10b) to the mold halves (2a, 2b) and second ends coupled together in rotation on a common shaft (12) movable, characterized in that said common axis (12) can move rse along a path (13) inclined relative to the plane (5) connecting the inclination of the path (13) being related to the asymmetry of opening of the two mold halves (2a, 2b) on both sides of the plane (5 ) of Union.
