Abstract
A blow molding machine for containers, having a conveyor path carrying a mandrel holder and pre-forming mandrels attached to the mandrel holders in an exchangeable manner by means of removable couplings, wherein each coupling has a mandrel clamping mechanism and a releasing element accessible form outside that can be adjusted at least relative to the mandrel holder for releasing the clamping mechanism. In the mandrel holder, particularly for use in a blow molding machine, the mandrel clamping mechanism is designed with a ball joint lock, and the ball joint lock can be released by means of a releasing element in order to exchange a performing mandrel.
Claims24
Blow molding machine for containers, in particular bottles, comprising a conveyor path carrying mandrel holders, pre-forming mandrels attached at the mandrel holders by means of releasable couplings in an exchangeable manner, and each coupling having a mandrel clamping mechanism and a releasing element accessible from outside that can be adjusted at least relative to the mandrel holder for releasing the clamping mechanism.
