Abstract
The invention relates to a novel knockout head of a casting mold. The novel knockout head comprises a fixing base. A lifting air cylinder is arranged on the upper surface of the fixing base. A plurality of ejector cores are arranged on the lower surface of the fixing base and correspond to sand shooting holes in position. The fixing base is of a hollow structure with an inner cavity, an air inlet pipe communicated with the inner cavity of the fixing base is arranged on the upper surface of the fixing base, and the air inlet pipe is provided with an electromagnetic adjusting valve. The ejector cores are connected with the fixing base through installing heads. Each ejector core is of a hollow pipe structure with an air conducting channel, and a plurality of vertically-arranged jet flow holes communicated with the air conducting channel of each ejector core are formed in the side wall of each ejector core. The jet flow holes are obliquely arranged downwards relative to the center axes of the ejector cores. The installing heads are rotationally connected with the fixing base through bearings, and provided with air ventilation cavities communicated with the inner cavity and the air conducting channels. The installing heads are provided with driven gears, and the adjacent installing heads are synchronously connected through engagement of the driven gears. The driven gear at the outermost end of one side is engaged with a drive gear, and the drive gear is connected with a drive motor through a belt.
