| description | The utility model belongs to the technical field of casting and provides an easily-fractured flow gate for cleaning precision castings easily. The easily-fractured flow gate mainly comprises cylindrical flow gate bodies, wherein one ends of the cylindrical flow gate bodies are connected with a gate stick, and the other ends of the cylindrical flow gate bodies are connected with castings; sunk annular notches I are radially formed in the upper edges of the cylindrical flow gate bodies, the longitudinal cross sections of the annular notches I are V-shaped, the annular notches I and the cylindrical flow gate bodies are coaxially arranged, the area of the cross section of the bottommost part of each annular notch I in the corresponding cylindrical flow gate body is equal to 40% of the area of the cross section of the cylindrical flow gate body, and each annular notch I forms an included angle of 60-90 degrees. Compared with the prior art, the novel easily-fractured flow gate has the advantages of simple process, convenience in operation, high operating efficiency and low production cost, and the castings can be directly knocked down without cutting. |
