Claim:
1. A system for injecting semisolid metal into a mould, said system comprising: a mould comprising a mould chamber suitable to receive the semisolid metal through an injection mouth; at least one press device for pressure-injecting the semisolid metal into said mould, said at least one press device comprising a cylinder having a substantially vertical axis (X-X), an injection chamber configured to receive and contain molten metal having a mouth for coupling to said injection mouth of said mould to enable direct injection of the semisolid metal from said injection chamber into said mould, and a thrust piston positioned within said injection chamber of said cylinder configured to travel toward said mouth of said injection chamber to force the semisolid metal from said injection chamber into said mould wherein said cylinder has passageways configured to receive cooling fluid that cools the molten metal received within said injection chamber to produce semisolid metal for injection into said mould; a positioning device supporting a blending device having an active portion and a cover, wherein said positioning device is configured to selectively move said active portion of said blending device into said injection chamber and simultaneously position said cover over said mouth of said injection chamber in order to temporarily close said injection chamber; and an actuating device that selectively drives said thrust piston to inject the semisolid metal from said injection chamber into said mould when said mouth of said injection chamber is connected to said injection mouth of said mould.
