The invention provides a multiphase flow pipeline mechanical wax removal simulated test device and a mould to manufacture wax deposit. The multiphase flow pipeline mechanical wax removal simulated test device comprises a testing station. The testing station is fixedly provided with a multiphase flow pipeline component. The multiphase flow pipeline component comprises a main pipeline. The main pipeline is provided with a wax deposit arranged in the axial direction and having a crescent-shaped cross section. The main pipeline is provided with a pipeline cleaner. The pipeline cleaner is connected with a rope. One end of the rope penetrates the main pipeline. The upper part at one end of the main pipeline is provided with a wax cleaning resistance detection mechanism. The wax cleaning resistance detection mechanism comprises a measured force sensor. One end of the upper part of the measured force sensor is connected with an electric winch drive mechanism. Observation mechanisms are parallelly arranged at intervals on one side of the main pipeline and can observe pipeline cleaning. The multiphase flow pipeline mechanical wax removal simulated test device further comprises a control system. The test device is capable of simulating the use of a mechanical mode to clean the wax in a multiphase flow pipeline and can find applications in the research on the wax removal of an oceanic petroleum transporting pipeline.
