Abstract
A cast molding method accomplishes the cast molding by a smelting chamber, a casting chamber, a hinge press system and a vacuum system. First, a metallic die is assembled in the casting chamber and then a metallic material is put in the smelting chamber. Next, the metallic material is heated up in a vacuum state and the casting chamber is pre-heated at a same time. After the metallic material in the smelting chamber has been melted down and the casting chamber has been vacuumized, the melted metallic material is filled into the metallic die, and then the hinge press system is turned on to cast mold the metallic die, resulting in a semi-solid product. After the semi-solid product has been cooled down, the product of cast molding is accomplished according to the present invention.
