The invention relates to the technical field of mold changing of injection molding machines, in particular to a rapid mold changing mechanism for injection molding machining and an injection molding machine thereof, and solves the problems that when an injection molding machine mold changing mechanism is used, a new mold can be installed only after an old mold is taken down and placed well, operation is inconvenient, mold positioning is generally not achieved when the mold is installed, and the mold changing efficiency is high. The injection molding machine comprises an injection molding machine mechanism, and two injection molding mold structures are arranged in the injection molding machine mechanism. Mechanical locking of the mold body is achieved by clamping the limiting insertion rods into the limiting grooves, meanwhile, the electromagnet is powered on, a magnetic conductive plate of the mold body is electromagnetically attracted through the electromagnet, electromagnetic locking of the mold body is achieved, the stability of the mold body is improved, and the service life of the mold body is prolonged. And the situation that the mold body is not mounted in place to cause mold slot positions during mold replacement is avoided.
