Abstract (en)
[origin: EP3147046A1] The riser base is an insert obtained by manual moulding or by blowing having an insulating or exothermal composition, which comprises hollow microspheres of aluminium silicate. The mould is made, mainly, of silica sand and presents a main cavity designed to be filled with molten metal to obtain a cast part and one or several auxiliary cavities. The insert fits into the auxiliary cavity made in the mould and presents an interior cavity configured to receive molten metal from a feeding riser or mini-feeding riser and an exterior geometry which coincides with the geometry of the aforesaid auxiliary cavity. The auxiliary cavity or cavities made in the mould itself, are disposed in such a way that, when the riser base is inserted into said auxiliary cavity, the interior cavity of the riser base is left in communication with said main cavity of the mould (part) to allow passage of the molten metal.
