direction and protrude from this on one side to As in F i g. 3, the outer cores can laterally have recesses 14 in the adjacent parts 5, 7 standing at right angles to them, so that hard sections can be screwed in. On the inner wall of the hollow body, this has the disadvantage that the assembly and removal of the frame or sash 15 reinforcements 16 of the mold core is cumbersome and results in 50. When demolding is first the middle that the core sections with a screw on the core part 6 pulled out and then the outer longitudinal bore will have to be provided. Ren core parts 5, 7, one after the other, to the middle, the object of the invention is therefore to create a mold core that is pushed in more than one and then, like the middle core part, that is quickly pulled out together.
