Abstract

A semi-solid injection forming device is characterized in that the semi-solid injection forming device comprises a horizontal injection cavity, a sealing mechanism and a horizontal pressurizing stirring mechanism; the horizontal pressurizing stirring mechanism comprises a stirring motor, a stirring rod, a piston rod and a plunger rod; a piston is arranged in the horizontal injection cavity in a sealed mode and can move horizontally; one end of the plunger rod is connected with the piston; and the other end of the plunger rod horizontally extends out of the horizontal injection cavity. The invention further discloses a forming method. Extruding casting and mechanical stirring are integrated, in the stirring process of melt, pressure is applied to the melt, pressure maintaining operation isconducted, the forming efficiency of finer crystal nucleus is improved, the nucleating number in unit volume is increased, the setting time is shortened, and the preparation efficiency is improved.

Description

technical field [0001] The invention relates to a semi-solid preparation device, and also relates to a semi-solid preparation method. Background technique [0002] Semi-solid forming technology includes rheological forming and thixoforming. This technology is a technology between solid forming and liquid forming (casting) that was first proposed by Professor M.C.Flemings of the Massachusetts Institute of Technology. A shaping technique. This technology integrates the advantages of plastic forming and casting technology, and has broad application prospects. The premise of realizing the engineering application of semi-solid forming technology is how to efficiently produce high-quality semi-solid slurry. Scholars at home and abroad have successively conducted related research on semi-solid slurry preparation technology. At present, the methods commonly used in this field and capable of preparing semi-solid slurry include stirring method (mechanical stirring method, electroma...
