PROBLEM TO BE SOLVED: To reduce the deposition of impurities by forming a weighing chamber in a slantly provided injection machine of a sleeve, and generating a stirring flow by the extrusion of a molten metal stock with every injection time from the sleeve. SOLUTION: The injection machine for low melting point metal is installed slantly in such a manner that a nozzle at the tip of a heating-holding cylinder is made downward. A weighing chamber communicating with the nozzle is formed of a sleeve fitted into the nozzle member. The sleeve is projected from the internal toe of the nozzle member, from the heel face to form the slant bottom face of a storage chamber, and the opening edge has a length located in the storage chamber of the nozzle chamber. The projecting part in the sleeve is piercingly provided with a circulation port so as to be close to the slant bottom face. COPYRIGHT: (C)2006,JPO&NCIPI
