[0002] When reprocessing hardware, a hot pressing device is required. Hot pressing requires a hot pressing mold. The hot pressing mold includes an upper mold and a lower mold. One mold can only be used for hot pressing of one hardware. Only after cooling can the hot pressing part be removed from the mold. Generally, after the hot pressing part solidifies, the upper mold can be removed without cooling, and the hot pressing part in the lower mold can be cooled before demolding. However, a lower mold matches one upper mold. Industrial hot pressing generally waits for the demolding to be completed before waiting for the next or next batch of hot pressing, which is inefficient and cannot be continuous.
