The invention relates to the technical field of hot presses, in particular to a hot press and a product feeding and discharging method. The hot press comprises a feeding mechanism, a discharging mechanism, a plurality of hot pressing mechanisms arranged between the feeding mechanism and the discharging mechanism, a transfer platform, a transfer mechanism and a bearing device arranged on the hot pressing mechanisms, and the transfer mechanism is used for transferring batteries between the transfer platform and the multiple hot pressing mechanisms; hot-pressing processing is completed on the battery on multiple stations through the multiple hot-pressing mechanisms, the production efficiency is greatly improved through full-automatic production, the hot-pressing mechanisms are double-layer hot-pressing mechanisms, and the productivity is greatly improved. The bearing device used for supporting the product is arranged on the hot-pressing mechanisms, the product is lifted through the bearing device, the avoiding position allowing the transferring mechanism to stretch in to grab the battery is formed, the problem that feeding is difficult is solved, and mechanical interference between the transferring mechanism and the hot-pressing mechanism when the battery is put into or taken out of the hot-pressing mechanism is avoided; the accuracy and flatness of the battery placing position are guaranteed, and the battery processing quality is improved.
