Claims27
A blow molding tool for a blow molding machine, comprising:
- two blow mold halves, each having at least one molding body in which at least one mold cavity is arranged, and
- a baseplate receiving the molding body,
- wherein an insulation block made of a thermally insulating material is arranged between the molding body and the baseplate such that the molding body is thermally insulated from the baseplate,
- the molding body has a rear side provided with channels providing heating/cooling circuits for a flow of a heating/cooling medium,
- the heating/cooling circuits are formed by the same channels in the insulation block and on the rear side of the molding body, wherein supply and discharge of the correspondingly temperature-controlled heating/cooling medium can be controlled by means of valves in such a way that the heating medium or the cooling medium can be introduced alternately into the channels.
