Abstract: A demolding method for extracting a ceramic product (1) from a half-part (2) of a mold comprises at least the following steps: positioning an extractor element (3), which has a contact surface (3s), at a visible surface (1a) of the product (1) partially housed in the mold half-part (2); extracting the product (1) and placing it in abutment against the contact surface (3s); dividing the contact surface (3s) into two separate, matching portions (3a, 3b) by moving a first portion of it (3a), which supports the product (1), away from its other portion (3b); releasing the product (1) onto a work and/or supporting element or table (4) matchingly shaped to be coupled to the first portion (3a) of the extractor element (3); moving the first portion (3a) and the supporting element or work table (4) away from each other. The invention also relates to an apparatus that implements this method.

Abstract: The present invention concerns a device for regulating the flow of a liquid used for the manufacture of ceramic products and which may be used in plants (2) with at least one elastically deformable pipe (3), for supplying/draining the liquid to/from a mould for the manufacture of the products; the device (1) comprises: an actuator (5), placed in contact with an outer surface (3a) of the pipe (3), to generate a controlled pressure (P5) on the outer surface (3a) of the portion of the pipe (3) with which it is in contact; fixed contrast elements (6) fitted to and acting on at least the outer surface (3b) of the pipe (3) opposite to the surface (3a) in contact with the actuator (5) and for a length (L6) comparable with the length (L5) in contact with the actuator (5), to enable the portion of the pipe (3), when the actuator (5) is activated, to be deformed in a controlled and uniform manner.

Abstract: An apparatus (1) for smoothing a product (2), in particular a semi-finished ceramic product, comprises: an abrasive tool (3) in the form of an endless belt (4) which is trained around at least one pair of pulleys (5, 6), at least one of which is power-driven; the belt (4) has an active section (7) and at least one passive section (8); the active section (7) removes material from the product (2), while the passive section (8) receives a regenerating treatment that restores the abrasive capacity of the tool (3); drive means (20) acting on the belt (4) in such a way as to enable the belt (4) itself to move in the space surrounding the product (2); means (10) for spraying a liquid on the belt (4), which has liquid absorption properties, said means (10) being located in the vicinity of the belt (4) itself; and negative pressure means (9) associated with the passive section (8) of the belt (4) and operating in such a way as to extract the liquid and the materials retained by the belt (4) and removed from the produc

Abstract: Ceramic sanitary wares are cast using equipment that comprises at least one mold made up of two halves presenting relative cavities in which the cast item is formed, rendered capable of movement to and fro along a predetermined direction toward and away from one another through the agency of a first actuator, in such a way that respective mating surfaces of the mold halves can be joined together or separated. Pressure forces acting on the mold halves from within are contained and controlled by a system associated directly with the mold halves, which comprises a mechanism acting on the system itself and on the halves of the mold in such a way as to create a gap affording a free passage to the mold halves when drawn together and distanced one from another. In this way, at least one of the halves can be rendered independent of the containment and control system for demolding purposes.

Abstract: Sanitary wares are pressure-cast on a single mold machine comprising a bed and two platens associated with the bed, each one supporting a respective mold half; one of the two platens is translatable along the bed in a longitudinal direction, whilst the other incorporates a tilting platen carrying the respective mold half and is rotatable about a horizontal axis extending perpendicular to the longitudinal direction; the accessibility to the mold halves and to the casting are improved and therefore the operations of demolding the green wares and transferring them to successive stages of manufacture are much facilitated, as also is the procedure for changing the mold.

Abstract: A porous mould for making sanitaryware comprises: two half-parts (2, 3) joined to each other to create a product forming cavity (4); one of the half-parts (2) has a first inlet opening (5) through which respective means (6) feed a liquid (7) under pressure into the product forming cavity (4); a variable volume element (8) located inside the cavity (4); second means (10) for feeding a fluid under pressure, acting on this element (8) and varying the volume of the element (8) between at least two limit states, namely, a least expanded, idle state and a most expanded working state, when the forming liquid (7) is fed in, and where the element (8) occupies a predetermined volume of the cavity (4) in such a way as to control the inflow of the liquid (7) along the surfaces of the cavity (4); means (11) for controlling and regulating the degree to which the element (8) is filled and the liquid (7) feed pressure, acting on the respective first feed means (6) and second feed means (10) in such a way as to correlate the

Abstract: A device for producing an opening or cavity in the side of a ceramic product during product molding in a mould with a molding cavity delimited by a molding surface which has a window, comprising a deformable punch, joined on the window, designed to project into or retract from the molding cavity, with the ability to vary its rigidity. The device comprises punch shape variation differential constriction means and actuator means for punch deformation, which together produce a controlled anisotropic punch deformation, which makes the punch project into the molding cavity.
