Anti-deformation engineering plastic filler framework structure and application thereof

The invention aims at providing an anti-deformation engineering plastic filler framework structure and application thereof, and belongs to the technical field of investment precision casting manufacturing, hole structures are evenly distributed in the filler framework structure so as to facilitate wax material mold filling, meanwhile, completely identical positioning protruding points are evenly distributed on the two sides, and the positioning protruding points are evenly distributed on the two sides of the filler framework structure so as to facilitate wax material mold filling. Therefore, the filler skeleton structure is located in the middle of the wax mold. When the wax mold is manufactured, an engineering plastic framework is added into the mold for wax pressing and wrapping of the framework, and as engineering plastic has good mechanical strength, dimensional stability and rigidity, the situation that plastic permanent deformation is generated in the subsequent trimming, combining, placing and shell ma
