A pressing punch for the production of ceramic products comprises a base plate (15, 115) provided with a seat (16, 116) which receives a thin plate (17, 117) containing on its outer side a thin vulcanized rubber or resin layer containing the impression to be applied onto the product. Magnetic attraction means (19, 119) for performing magnetic fixing of the thin plate once it has been placed inside the seat (16, 116) are provided between the thin plate and seat. The base plate (15, 115) is also provided with actuatable pushing means (22, 122, 151 ) for moving upon operation the thin plate (17, 117) away from the seat (16, 116) against the retaining action of the magnetic attraction means (19, 119) so as to allow removal and replacement thereof. A method for raising the thin plate is also described. |
