The invention discloses a linkage mold opening mechanism of a sliding block type wax mold. The linkage mold opening mechanism comprises a connecting assembly, a lower mold sliding block, a linkage assembly and a power assembly. The connecting assembly comprises a lower workbench and an upper workbench. A bottom plate, a lower die plate and an inclined pressing frame are sequentially arranged above the lower workbench. An upper template is arranged on the lower bottom surface of the upper workbench; a lower die sliding block is arranged on the upper end surface of the lower template; the linkage assembly comprises a guide rail rack arranged on the lower bottom face of the lower die sliding block and connected with the lower die plate in a clamped mode, and a linkage gear rotationally connected to the lower die plate in a clamped mode and connected with the guide rail rack in a meshed mode. The power assembly is used for driving the linkage gear to rotate; the low-pressure turbine working blade wax mold is reas
