摘要

A clamping device for blow molding machines which comprises a body (2), tie bars (3) horizontally supported on the body (2) to be longitudinally movable, a front platen (4) and a rear platen (5) arranged on front and rear ends of the tie bars (3), respectively, a movable platen (6) facing the front platen (4) and arranged on the tie bars (3) to be longitudinally movable, and split mold dies (7, 8) provided on the side where the front platen (4) and the movable platen (6) face each other. Provided on the body (2) are a crank mechanism (9) and a drive source (10) for transmitting a drive force to a crank shaft (90) of the crank mechanism (9). The rear platen (5) and the movable platen (6) are connected to a crank arm (91) of the crank mechanism (9) via connecting rods (92, 93).
