Abstract

Mould for casting artificial stone. Block of rubber-like thermoplastic is shaped. Before hardening, at least one natural stone is pressed into it, and is removed as soon as possible, before the final cooling of the block. A mould space is formed, with the shape of the natural stone, after cooling. Pref. the plastics is PVC based.

Description

  

  
 



  Verfahren zur Herstellung einer Giessform zur Herstellung eines Kunststeines
Die Erfindung bezieht sich auf ein Verfahren zur Herstellung einer Giessform zur Herstellung eines Kunststeines.



   Die Erfindung bezweckt, eine Giessform zu schaffen, in der natursteinähnlich gebildete Kunststeine gegossen werden können.



   Das erfindungsgemässe Verfahren ist dadurch gekennzeichnet, dass ein Block aus einem kautschukähnlichen, thermoplastischen Kunststoff geformt wird, in den vor dem Aushärten durch Erkalten mindestens ein Naturstein eingepresst wird, und dass der Naturstein frühestens vor dem endgültigen Erkalten des Blockes aus diesem entfernt und so ein Formhohlraum gebildet wird, der die Gestalt des Natursteins nach dem Erkalten beibehält.



   Die Zeichnung zeigt als Ausführungsbeispiel eine blockförmige Giessform 1 zur Herstellung eines Kunststeines teilweise im Schnitt. Sie besteht aus einem   kau    tschukähnlichen, thermoplastischen Kunststoff. Diese Giessform ist durch Einpressen des erweichten Kunststoffes in eine äussere Blockform hergestellt.



   In den noch weichen Kunststoff wird ein Naturstein stück 2 oder werden mehrere Natursteinstücke in der Anordnung eines Mauerverbandes eingepresst. Diese bilden den Formhohlraum 3 als Abdruck der Konturen 4 des Natursteins aus.



   Nach dem Aushärten des Kunststoffs oder kurz vor dem endgültigen Erkalten desselben kann der Naturstein,   dér    gemäss der Zeichnung noch im Formhohlraum liegt, aus diesem entnommen werden.



   Die Erfindung ist nicht auf das dargestellte und beschriebene Ausführungsbeispiel beschränkt; vielmehr können Einzelheiten dem jeweiligen Verwendungszweck angepasst werden, ohne vom grundsätzlichen Erfindungsgedanken abzuweichen.



   Die Giessform kann aus einem bekannten Kunststoff auf PVC-Basis bestehen; diese Kunststoffe können nämlich wieder eingeschmolzen werden. Nicht mehr gebrauchte Giessformen können daher aufgearbeitet und der Kunststoff dann erneut zu neuen Giessformen verarbeitet werden. 



  
 



  Process for the production of a casting mold for the production of an artificial stone
The invention relates to a method for producing a casting mold for producing an artificial stone.



   The aim of the invention is to create a casting mold in which artificial stones formed similar to natural stone can be cast.



   The method according to the invention is characterized in that a block is molded from a rubber-like, thermoplastic material, into which at least one natural stone is pressed before it hardens by cooling, and that the natural stone is removed from the block at the earliest before the block has finally cooled, thus creating a mold cavity is formed, which retains the shape of the natural stone after cooling.



   The drawing shows, as an exemplary embodiment, a block-shaped casting mold 1 for producing an artificial stone, partially in section. It consists of a rubber-like thermoplastic material. This mold is made by pressing the softened plastic into an outer block mold.



   In the still soft plastic a piece of natural stone 2 or several pieces of natural stone are pressed in the arrangement of a wall association. These form the mold cavity 3 as an imprint of the contours 4 of the natural stone.



   After the plastic has hardened or shortly before it has finally cooled, the natural stone, which according to the drawing is still in the mold cavity, can be removed from it.



   The invention is not limited to the illustrated and described embodiment; rather, details can be adapted to the respective purpose without deviating from the basic inventive concept.



   The casting mold can consist of a known plastic based on PVC; these plastics can namely be melted down again. Casting molds that are no longer used can therefore be refurbished and the plastic can then be processed again to make new casting molds.
