Abstract: Mould for producing plastic items obtained by the injection of thermoplastic material of the “hot melt” or polyamide type, the mould being made of flexible vulcanised silicone, rubber or other elastomers, the mould being formed by two parts which, when facing each other and attached, generate a series of compartments and channels that allow for the introduction of the melted thermoplastic material and the filling of the cavities with the shape of the item desired, and, in turn, allow for a vacuum to be generated, also removing the inside air from the mould by means of a series of conduits and channels; and a method or methodology for producing said plastic items by means of said mould, allowing for the reproduction of short and medium series of items produced with plastic materials, and in which a control system and a mould incorporating a means to be identified can be added to the method.

Abstract: A supply device of molten metal for application in semi-automatic centrifuge machines with one plate or for automatic machines with three or more plates to collect the molten metal from the furnace, take it to the centrifuge and pour it into the centrifuge. The supply device occupies minimum space and allows both for a side or back furnace configuration. The device includes an automatic and programmable assembly having an arm that is radially secured on one end to the rotating shaft of a geared motor fitted to the centrifuge. On the other, the device is articulated to another vertical arm, holding a ladle at its lower end. The operation of the device is synchronized with the operation of the centrifuge, increasing productivity, reducing hazards for workers, reducing energy consumption, and improving the finish of the final product.
