In actual production, in order to shorten the retention time of the cover plate in the molding region 61, the cover plate also slides into the molding region 61 synchronously in the process of descending the heat insulation plate 9, so that the lifting stroke of the heat insulation plate 9 is required to be enough to avoid the sliding stroke of the cover plate when the cover plate translates from the bending region 51 to the molding region 61 on the machine 1, and therefore the lifting stroke of the heat insulation plate 9 needs to be larger than the lifting stroke of the cooling table 621, so that the cover plate is prevented from being scratched by a descending partition plate when the cover plate is not completely transposed into the molding region 61. The length of the second link 97 is thus greater than the length of the first link 96, i.e., the first rotary cylinder 93 is disposed at a side close to the first boss 94.
