By the swap which the directly the mold cavity edges of the molded part 15 against the edges of the for the recess delimiting the hollow body on the molded part 18 and also the edges of the molded part 16 point. Apart from being pressed against the edges of the molded part 19, these parts can be pressed assumption, the shape of the plastic, which is still warm, will be very simple in the opposite direction. and molded parts 15, 18 and 16, 19 pressed together in a simple manner on the mold support plates to be brought. Their production is thus welded relatively along these edges and at the same time cheap. Also converting the device for a 60 different from the rest of the plastic in the blow chamber Hollow bodies can be separated quickly and easily. This creates the desired hollow ways take place. Because they move relative to each other.
