The invention provides a cooling apparatus for a hot nozzle of an injection mould and belongs to the technical field of plastic mould manufacturing. The invention solves problems of poor cooling effects and uncontrollable temperature in the hot nozzle of an injection mould in the prior art. The injection mould in the invention includes a moving die, a fixed die and the hot nozzle which passes through the fixed die. The cooling apparatus includes a cooling water well, a water inlet flow path and a water outlet flow path which are all arranged in the moving die. The upper part of the cooling water well is a cooling chamber which is arranged below the hot nozzle. The water inlet flow path and the water outlet flow path are both communicated with the cooling water well. A flow guide member is arranged inside the cooling water well and is used for guiding cooling water flowing into the cooling water well from the water inlet flow path to pass through the cooling chamber and then flow into the water outlet flow pat
