PCT No. PCT/AT95/00220 Sec. 371 Date Apr. 19, 1997 Sec. 102(e) Date Apr. 19, 1997 PCT Filed Nov. 16, 1995 PCT Pub. No. WO96/14750 PCT Pub. Date May 23, 1996Disclosed are devices and processes for producing baked thin-walled shaped articles from baking or pouring mixtures which expand during the baking process. The bottom half (18) of a baking mold (16) for producing thin-walled shaped articles is accommodated in the bottom tongs section (13) of a pair of baking tongs (7) and the top half (17) of the baking mold is accommodated in the top tongs section (15) of the tongs (7). The mold halves (17, 18) and tongs sections (13, 15) are provided with stop surfaces (68c, 64d) and sealing surfaces (17a, 18a, 21a, 22a) and are in mutual contact when the baking mold (16) is closed. At least one clamp device (30, 31) is provided to press the mold halves (17, 18, 21, 22) of the closed baking mold (16) together; said clamp device forces at least the two mold halves (17, 18) of the closed baking mold (16) together with a predetermined clamping force during clamping and eliminates at least the play between them. The upper tongs section (15) of the baking tongs (7) can be guided via a lateral guide strut (14) in the lower tongs section (13). With baking tongs which have two-part dies in the lower tongs section, mechanisms can be provided between the baking tongs in the tongs chain in the baking oven to open or close the dies when passing a deviation in the chain. |
