The invention provides an automatic production injection mold with an automatic bottle capping function and a using method thereof. The automatic production injection mold with the automatic bottle capping function comprises a formwork structure assembly, a thread demoulding mechanism assembly, a jacking assembly, a mold parting control assembly, a mold forming assembly and a before-jacking automatic capping assembly. As for the layout of the mold, the mold is provided with four cavities, and a casting system is in a hot runner nozzle direct-casting mode. By adoption of the injection mold of the technical scheme, the actual operation problem that during injection molding production of flip combined plastic bottle caps, subsequent manual capping is needed after bottle caps are subjected to injection molding and consequently the production efficiency is low is solved, full-automatic injection molding production and automatic capping operation of the flip combined plastic bottle caps can be achieved through a simple mechanism, the product forming quality is effectively ensured, and the production efficiency is effectively improved; and the automatic production injection mold with the automatic bottle capping function is reasonable in structural design, compact in structure, stable in operation, safe, reliable and convenient to use.
