Document Type and Number:
WIPO Patent Application WO/2014/168279
Kind Code:
A1
Abstract:
The hybrid die casting molding apparatus according to the present invention comprises a hybrid mold (10) comprising: a fixed die (20) and a movable die (30) which can be coupled to and separated from each other; cavities (40) formed in the fixed die (20) and movable die (30), for casting/molding engine brackets; injection gates (60) connected from runners (50), from which molten metal is supplied, for injecting the molten metal into the cavities (40); and overflow vents (70) for creating a high vacuum in the cavities (40) and acting as passages through which the molten metal overflows from the cavities (40), thus the apparatus being characterized by manufacturing engine brackets (100A, 100B, 100C, 100D) having various forms while satisfying exacting conditions, such as molten metal flow together with oxide distribution and the filling condition of each gate, through which the molten metal is injected, and particularly by easily mass-producing the engine brackets (100A, 100B, 100C, 100D) while allowing same to have the rigidity required thereof.
