After the uppermost hot pressing plate 5 contacts the several hot pressing plates 5 below, the laminate 2 that is compacted and positioned is hot-pressed. After the hot pressing is completed, several hydraulic cylinders 3 are started again to drive the upper part of the uppermost hot pressing plate 5, so that the uppermost hot pressing plate 5 cooperates with several T-shaped limit rods 6 to drive the several hot pressing plates 5 below to reset, until several horizontal push plates 14 are respectively set opposite to the upper ends of the several hot pressing plates 5 below.

[0025] The upper ends of the several hot pressing plates 5 below are each provided with a limiting mechanism, and the several laminates 2 are placed between two adjacent hot pressing plates 5 and pressed against the limiting mechanism.
