Digitalization processing method of gypsum mould

The invention discloses a method for digital processing a gypsum mold, belonging to the crossed technical field of precision casing and digital control processing. The method comprises the steps as follows: a gypsum mixture is made into a block to be dried and calcined into a gypsum block to be processed firstly; a three-dimensional CAD model of the gypsum mold is transformed into digital control processing code directly; the gypsum block is arranged on a processing device and milling processing is carried out under the drive of the digital control processing code; waste residue produced during processing is taken away by blew-out air current or is absorbed by a dust collector; and finally, the well processed gypsum mold is cast to obtain a cast. Compared with the existing gypsum patternmaking method, the processing method has high processing precision, saves the step for manufacturing a mold, reduces the processing procedures, shortens the production period and reduces the production cost. The method is especially suitable for processing and manufacturing a single piece or a small batch of precise cast.
