Descrizione del Brevetto d'invenzione Industriale dal titolo: Description of the Industrial Invention Patent entitled:
“Procedimento per la costruzione rapida di stampi per manufatti in argilla", "Procedure for the rapid construction of molds for clay products",
Descrizione Description
La presente invenzione si riferisce ad un procedimento per la costruzione rapida di stampi per manufatti in argilla, quali tegole e simili. The present invention relates to a process for the rapid construction of molds for clay articles, such as tiles and the like.
E'noto come la costruzione di stampi da usare con presse per la produzione di manufatti in argilla sia quanto mai laboriosa, vista la natura del materiale da lavorare, e la notevole usura degli stampi che ne deriva. It is known how the construction of molds to be used with presses for the production of clay products is extremely laborious, given the nature of the material to be worked, and the considerable wear of the molds that derives from it.
Detti stampi vengono prodotti in acciaio, acciaio che deve essere sottoposto a trattamento termico apposito affinchè la superficie dello stesso rimanga -dura e .resistente nel tempo per gli usi ai quali detto stampo è destinato. Said molds are produced in steel, steel which must be subjected to a specific heat treatment so that its surface remains hard and resistant over time for the uses for which said mold is intended.
Attualmente, allo scopo „di ovviare a questi inconvenienti, si è adottata'una tecnica con la quale sulla faccia superiore ed inferiore degli stampi vengono costruiti i positivi del manufatto in argilla da stampare, quindi tra detti positivi viene colata una resina ad indurimento, tipo resina epossidica o simile, con la quale colata si ottengono i negativi del manufatto da stampare. Currently, in order to overcome these drawbacks, a technique has been adopted by which the positives of the clay product to be molded are constructed on the upper and lower face of the molds, then a hardening resin is poured between said positives, such as epoxy resin or similar, with which the negatives of the product to be printed are obtained.
Questo è già un notevole miglioramento rispetto alla tecnica tradizionale alla quale si è accennato prima, tuttavia con questa tecnica l'inconveniente principale sta nell'usura della membrana, in gomma o simile, che viene solitamente interposta tra stampo ed argilla. This is already a considerable improvement with respect to the traditional technique mentioned above, however with this technique the main drawback lies in the wear of the membrane, made of rubber or the like, which is usually interposed between the mold and clay.
Scopo della presente invenzione è ovviare a questo inconveniente dell'usura della membrana interposta tra stampo ed argilla. The object of the present invention is to obviate this drawback of the wear of the membrane interposed between the mold and clay.
Secondo una prima forma di realizzazione del trovato si crea nello stampo un supporto in gesso e detto supporto viene rivestito con un materiale avente ottime proprietà anti-usura, quale un materiale polimerico rinforzato con acciai ceramici . According to a first embodiment of the invention, a gypsum support is created in the mold and said support is coated with a material having excellent anti-wear properties, such as a polymeric material reinforced with ceramic steels.
Secondo una seconda forma di realizzazione del trovato vengono creati dei tasselli in resina, poi rivestiti con il materiale anti-usura sovracitato, detti tasselli così rivestiti venendo inseriti nello stampo e fissati in loco con appositi mezzi di fissaggio. According to a second embodiment of the invention, resin plugs are created, then coated with the aforementioned anti-wear material, said plugs thus coated being inserted into the mold and fixed on site with suitable fastening means.
Come si è detto, il materiale anti-usura citato ed usato nelle due forme di realizzazione succitate è un prodotto bicomponente costituito da una matrice polimerica rinforzata con acciai ceramici . As stated, the anti-wear material mentioned and used in the two aforementioned embodiments is a two-component product consisting of a polymer matrix reinforced with ceramic steels.
Il trovato verrà ora descritto con particolare riferimento ai disegni allegati, forniti a titolo d'esempio non limitativo, in cui: The invention will now be described with particular reference to the attached drawings, provided by way of non-limiting example, in which:
Fig. 1 è uno schema illustrante due positivi da inserire in uno stampo; Fig. 1 is a diagram illustrating two positives to be inserted in a mold;
Fig. uno schema illustrante l'accoppiamento dei due positivi di Fig. 1, tra i quali verrà colata resina; Fig. A diagram illustrating the coupling of the two positives of Fig. 1, between which resin will be poured;
Fig. 3 è uno schema illustrante un semistampo secondo la prima forma di realizzazione del trovato; e Fig. 3 is a diagram illustrating a half-mold according to the first embodiment of the invention; And
Fig. 4 è uno schema analogo a Fig. 3 illustrante un semistampo secondo.la seconda forma di realizzazione del trovato. Fig. 4 is a diagram similar to Fig. 3 illustrating a half-mold according to the second embodiment of the invention.
Nelle Figure 1 e 2, con 1 e 3 sono indicati i positivi dei manufatti da ottenere secondo la tecnica precedente più .avanzata, e citata in precedenta. In Figures 1 and 2, 1 and 3 indicate the positives of the manufactured articles to be obtained according to the more advanced prior art, cited above.
Tra detti positivi l e 3 viene colata della resina 5 che viene a costituire, una* volta indurita, il negativo del manifatto da ottenere. Resin 5 is poured between said positives 1 and 3 which, once hardened, forms the negative of the product to be obtained.
Detto negativo 5 è fissato al positivo superiore 1 con mezzi idonei di fissaggio quali viti 7 o simili. Said negative 5 is fixed to the upper positive 1 with suitable fastening means such as screws 7 or the like.
In Fig. 3 è indicata una prima forma di realizzazione del trovato. In Fig. 3 a first embodiment of the invention is indicated.
Secondo detta prima forma di realizzazione, si crea nello stampo 9 un supporto 11 in gesso o simile e detto supporto II viene rivestito con un materiale 13 avente ottime proprietà anti-usura, quale un materiale polimerico rinforzato con acciai ceramici . According to said first embodiment, a support 11 made of gypsum or the like is created in the mold 9 and said support II is coated with a material 13 having excellent anti-wear properties, such as a polymeric material reinforced with ceramic steels.
In Fig. 4 è indicata una seconda forma di realizzazione del trovato. In Fig. 4 a second embodiment of the invention is indicated.
Secondo detta seconda forma di realizzazione, vengono creati dei tasselli 15 in resina, poi rivestiti con il materiale 13 anti-usura sovracitato, detti tasselli 15. così rivestiti venendo inseriti nello stampo 9 e fissati in loco con appositi mezzi di fissaggio 17. According to said second embodiment, resin plugs 15 are created, then coated with the aforementioned wear-resistant material 13, said plugs 15. thus coated being inserted into the mold 9 and fixed on site with suitable fastening means 17.
Come si è detto, il materiale 13 anti-usura citato ed usato nelle due .forme di realizzazione succitate è un prodotto bicomponente costituito da una matrice polimerica rinforzata con acciai ceramici. As stated, the anti-wear material 13 mentioned and used in the two aforementioned embodiments is a two-component product consisting of a polymeric matrix reinforced with ceramic steels.
Un esempio di detto materiale è quello noto con il marchio distintivo BELZONA 1111. An example of this material is the one known by the distinctive brand BELZONA 1111.
