Embodiment 1
[0019] Embodiment 1: a metal component casting process, it comprises the steps:
[0020] (1) Manufacture pattern: After polishing the finalized metal components or the newly produced product model, wipe the surface with pure cotton cloth, and then apply Vaseline evenly on the surface;
[0021] (2) Silicone outer mold: a silicone rubber mold made of silicone rubber by multi-layer smearing or three-dimensional pouring with a pouring port reserved, and gypsum is used as a foil mold for the outside.
[0022] (3) Wax mold making: Melt the paraffin, pour it into the silicone mold through the sprue, and form a hollow paraffin mold after cooling;
[0023] (4) Modeling: a. Pour plaster into the inner cavity of the hollow paraffin wax model, and perform surface finishing after the inner cavity gypsum solidifies to make a solid paraffin wax model; b. According to the shape of the solid paraffin wax model, weld the pouring port and the solid paraffin wax model Riser system, and then atta...
