Abstract
Manufacturing process of a stone providing for the following steps: positioning a die and a base platform under punches of a press, filling cavities of the die with a sand layer, placing a tube on the sand, actuating the actuation means to actuate the punches from the idle position to the operating position so that each punch presses the tube in the sand and presses the sand in the cavities of the die, actuating the actuation means to raise the punches, placing the stones in a drying station, extracting the solidified sand inside the tube from each stone, and placing a lighting device in the tube.
Claims9
Manufacturing process of a stone comprising the following steps:
- a) providing a base platform;
- b) providing a horizontal die comprising a series of through cavities along a vertical axis;
- c) providing a press with a punch for every cavity of the die;
- said press comprising actuation means for a simultaneous actuation of all punches;
- said actuation means being configured in such manner to actuate each punch from an idle position, wherein each punch is raised with respect to the die, to an operating position, wherein each punch is lowered and inserted in the cavity in order to press the material contained in the cavity of the die,
- d) actuating the actuation means so that the punches are in idle position;
- e) positioning the die under the punches in such manner that each cavity of the die is surmounted by a punch;
- f) actuating the base platform in such manner to place the base platform under the die;
- said die being positioned on said base platform so that all cavities of the die are closed in lower position by said base platform;
- g) filling the cavities of the die with a sand layer;
- h) placing a tube on the sand;
- said tube having a height equal to or lower than the depth of the cavity and said tube being provided with a longitudinal hole, a lower mouth directed downwards and an upper mouth directed towards the punch;
- i) actuating the actuation means to actuate the punches from the idle position to the operating position, so that each punch presses the tube in the sand and simultaneously presses the sand inside each cavity of the die;
- said stones being provided with an upper surface directed upwards and a lower surface directed downwards;
- said tube being inserted in the stone with the upper mouth of the tube flush with the upper surface of the stone;
- j) actuating the actuation means to raise the punches and bring the pounces back to the idle position;
- k) raising the die upwards so that all stones are placed on the base platform (3);
- l) placing the stones, which are arranged on the base platform, in a drying station in order to let all stones solidify;
- m) extracting the solidified sand inside the tube from each stone so that the longitudinal hole of the tube is free;
- n) placing a lighting device in the longitudinal hole of the tube.
