Definitions

  • the present invention relates to a mold for pressing ceramic tiles, particularly according to batches having variable shapes and/or contours, i.e., to a mechanical device that is provided with one or more impressions for molding ceramic tiles from a powdered earthy mass, which is divided into an upper mold part and a lower mold part, which are fixed so as to be mutually opposite within the working area of the press, wherein each one of said mold parts must be made suitable for molding tiles having a shape and/or contour that differ partially or completely from the ones provided initially; the parts of such a mold are also the subject of a patent application.
  • molds which are provided with one or more large or full-size impressions and are suitable, if necessary, to include vertically movable blades in order to divide the earth poured into each large impression into two or four portions, in order to obtain a corresponding number of tiles of smaller size, for example with at least two sides that are submultiples of the side of the large impression.
  • the aim of the present invention is to solve the problem of finding a mold and/or mold parts that are adapted, in each instance, to form ceramic tiles that have a different format, even a multiple or submultiple of the initial one, or in any case a multiple or submultiple of one of the formats that coexist in said mold, and/or having contours that are different from the usual rectangular or square ones, such as a broken-line or otherwise curvilinear or mixed contour, advantageously without having to disassemble the mold completely, i.e., rapidly, cheaply and for any possible variation in format and/or contour, even without making a distinction in terms of mold type, be it of the so-called mirror plate type, or of the loose powder transfer type or of the so-called retracting type.
  • the above aim is achieved by adopting a mold that provides, directly at manufacture, the splitting of the body of the mold part into at least two components: one constituted by an active element, which has at least one cavity that constitutes the receptacle for the impression that is designed to receive the earth, or means that otherwise cooperate with at least that impression to form the tile, the other component being constituted by a framework or base, in which the active element, constituted in any manner, with impressions that are identical or otherwise different for any division and/or contour variation, can be inserted and fixed removably and interchangeably, even if the mold part remains fixed to the press; at least one of said active element cavities encloses an impression that is provided with at least one diaphragm that divides said impression into a plurality of impressions and/or elements for forming the tile contour with any shape: broken line, curvilinear or mixed.
  • each mold part in order to introduce and fix in each instance therein, detachably and interchangeably, the active element that is adapted to form tiles having certain formats and/or contours according to a program, replacing it when necessary with another element provided with different formats and/or contours in order to change the production program, and so forth.
  • Each mold part, originally fitted in the work area of the press, is provided with the suitable active element, intended either to produce large tile formats or to produce small tile formats; in any case, it is possible to provide, or otherwise add subsequently, one or more active elements for each mold part, said elements being manufactured in the workshop and available in the ceramic facility in order to replace them rapidly in the cavities of the frameworks of the mold parts when necessary, without having to disconnect and reassemble said frameworks with respect to the press.
  • the reference numeral 1 designates a framework of the upper mold part, which is provided for example with an extractable slider or carriage 2, which in this case acts as an active element (both in the upper mold part and in the lower mold part), which encloses cavities 3 lined by hardened strips 4, which delimit peripherally the walls of tile impressions 5 and partially delimit smaller impressions 6 and 7;
  • the reference numeral 8 designates a transverse bar for locking the active element 2;
  • the reference numerals 9 and 10 designate diaphragms with a tapering right-angled cross-section, the last one being divided for example into a central cross 11 ( Figure 3), and four segments 12 for dividing large impressions such as 5, or even an integral diaphragm 10a;
  • the reference numeral 13 designates cup-shaped elements, in which the bottom acts as a flange for fixing not only the strips but also the diaphragms to the active element 2 by means of axial through screws 14 ( Figure 4);
  • the reference numeral 15 designates screws for fixing the active element 2
