The invention discloses a powder-injection wax-injection integrated structure. The integrated structure comprises a wax-injection area and a powder flapping area, wherein the wax-injection area comprises a wax injection nozzle capable of injecting wax; the powder flapping area comprises a powder blowing nozzle capable of blowing powder; the integrated structure also comprises a fixture structure similar to a clamp die and a driving device; the driving device can be used for pushing and pulling the fixture structure to the wax-injection area or the powder flapping area. A manual powder flapping operation procedure is replaced by a mechanical operation mode of firstly flapping the powder and then injecting the wax, the time is saved, the efficiency is improved, and the cost is reduced.
