Abstract
The utility model discloses a quick die changing device of a blow molding machine. A support is vertically installed at the top end of the frame, and a second sliding rail on one side of the support is connected with a lifting sliding block and a lifting plate. A polished rod is arranged in a rectangular groove in the tail end of the lifting plate, and the first movable block and the second movable block slide on the polished rod and are connected with the first containing plate and the second containing plate respectively. A threaded rod in the rectangular groove is in threaded connection with the first movable block and the second movable block, and distance adjustment is achieved through transmission of a motor, a chain wheel and a chain. Lifting chain wheels are arranged at the top end and the bottom end of the support respectively and connected through a lifting chain, the lifting chain is connected with a lifting sliding block, a balancing weight on a first sliding rail on the other side of the support is also connected with the chain, and a lifting motor at the top end of the movable frame drives a synchronizing shaft through the chain wheels and the chain to achieve lifting. Universal wheels are arranged at the bottom of the movable frame. The device can separately mount molds, can be operated in a mold opening state of the blow molding machine, is high in mold changing efficiency, can be adjusted to adapt to different molds, is stable in structure, and is convenient to move in a working site.
