PURPOSE: A water jet blower assembly for the injection of plastic is provided to easily couple a water jet head and a water jet injection nozzle and to improve the production of plastic. CONSTITUTION: A water jet blower assembly for the injection of plastic comprises a water jet head(10), an abrasive nozzle(20), and a water jet injection nozzle(30). The water jet head comprises a converging pipe and an abrasive feeding unit. The abrasive feeding unit is composed of an abrasive inlet(15a) and an abrasive outlet(15b). The abrasive inlet is formed on the surface of the converging pipe. The abrasive outlet moves an abrasive inside the converging pipe. The abrasive nozzle accelerates the injection speed of the abrasive. The water jet nozzle is composed of an insertion pipe(31), a locking sill(31a), a converging unit(32), and an acceleration nozzle(33). The insertion pipe is pressed to the inner surface of a pressing pipe of the water jet head. The locking sill has elasticity. The converging unit accelerates the injection speed of high-pressure flowing water and mixes the flowing water with the abrasive. The acceleration nozzle increases the moving speed of the mixture.
