Abstract

This invention discloses a position adjustment device and method for a mold holder in a blow molding machine, comprising a pair of string-length mechanisms. Each string-length mechanism includes a support column, a connecting seat at the top of the support column, and a positioning shaft assembly and a positioning sleeve assembly on the connecting seat. The positioning shaft assembly includes a vertically arranged positioning shaft, which is fixedly mounted on a positioning shaft support and is movable up and down between the positioning shaft support and the connecting seat. The positioning sleeve assembly includes a positioning sleeve, which is fixedly mounted on a positioning sleeve support and is movable up and down between the positioning sleeve support and the connecting seat. The mold holder on the rotary seat is adjusted using the above-mentioned position adjustment device in the blow molding machine. The advantages of this invention are: the adjustment device has a simple structure, the adjustment method is simple, all installation and adjustment are very convenient, and it can ensure the accuracy of the mold holder position in the blow molding machine, thereby ensuring the efficient operation of the blow molding machine.
