Abstract

A hot-pressing machine mainly has two supporting frames and a turnover device. The turnover device of the hot-pressing machine includes a loading seat, a sliding assembly disposed on two sides of the loading seat and disposed on the supporting frames. A protrusion protrudes outwards from two sides of the loading seat. A prop surface is formed on an upper edge of the protrusion. A sliding hole is formed on each supporting frame, A top edge of the sliding hole has an upper edge surface. The protrusion is adapted to penetrate through the sliding hole to be pivotally connected to a sliding seat of the sliding assembly. Accordingly, after the loading seat is pushed upwards by a distance, the prop surface of the loading seat is firstly in contact with the upper edge surface and supported by the upper edge surface to thereby prevent the force from gathering around a pivot part where the loading seat and the sliding seat are pivotally connected to each other during the movement, which therefore prevents the pivot part from being damaged, prolongs the service life, increases the durability, and reduces costs of the future maintenance.
