[0036] The specific usage and function of this embodiment are as follows:

[0037] When using this product, first check whether the internal mechanisms of the injection mold with mold cavity cleaning function are complete. When cleaning the inner cavities of the fixed mold base 4 and the movable mold base 3, the telescopic rod 7 drives the first connecting rod 10 to move to the inner cavity position of the fixed mold base 4 and the movable mold base 3. As the motor 9 rotates, the first connecting rod 10 is vertically located between the inner cavities of the fixed mold base 4 and the movable mold base 3. Then the pump 24 starts to work to draw water from the water tank 23 into the interior of the spray ring 21, and sprays it through the nozzle 22 to spray the inner walls of the inner cavities of the fixed mold base 4 and the movable mold base 3. Then the telescopic rod 7 and the motor 9 drive the first connecting rod 10 to rotate and retract. The telescopic rod 7 at the other end drives the second connecting rod 11 to move to the inner cavity position of the fixed mold base 4 and the movable mold base 3, and drives the third connecting rod 11 to rotate through the motor 9 to make it vertically located between the inner cavities of the fixed mold base 4 and the movable mold base 3. As the servo motor rotates, the turntable 8 starts to rotate, causing the first connecting plate 13 on the outer side of the turntable 8 to swing. Since the second connecting plate 14 is sleeved on the outer side of the first connecting plate 13, and a rivet is movably inserted between the first arc groove 16 and the second arc groove 15 opened at the same position of the first connecting plate 13 and the second connecting plate 14, the second connecting plate 14 is thrown out under the action of centrifugal force, so that the brush at one end of the second connecting plate 14 fits against the inner wall of the inner cavity for cleaning. After the cleaning is completed, the telescopic rod 7 and the motor 9 drive the second connecting rod 11 to be retracted. The first connecting rod 10 is re-erected between the inner cavities of the fixed mold base 4 and the movable mold base 3 under the action of the telescopic rod 7 and the motor 9. The hot air blower 25 is started to generate hot air to use the drying plate 18 to dry the water stains in the inner cavity. After the drying is completed, the first connecting rod 10 can be retracted.
