MOLD CLAMPING DEVICE OF BLOW MOLDER

摘要

PROBLEM TO BE SOLVED: To realize the prevention of molds from deviating and the pins and the holes of the molds from wearing, the improvement of the lives of the molds, the prevention of parting lines from poor missregistering and burrs from poor pinching-off (whiskers from developing) by a method wherein a horizontal bending toggle mechanism locates between an upper rod and a lower rod, which hold respective mold parts openably and closably so as to clamp the molds by utilizing the compressive forces of the respective rods. SOLUTION: This mold clamping device of a blow molder has a constitution for preventing parting lines from deviating, burrs from poor pinching-off and the like by providing the respective clevises 7a and 8a provided at both the ends of a toggle mechanism 9 at the intermediate position between an upper rod 19a and a lower rod 19b and bending and moving horizontally the respective toggle pieces 7 and 8 of the toggle mechanism normal to the hanging-down direction of a parison for carrying out the mold clamping by means of the compressive forces of respective rods 19a and 19b.
