Gate stick and preparation process

The invention discloses a gate stick which comprises a gate stick body and a gate cup, the gate stick body is provided with at least one small-included-angle structure, and a preparation process of the gate stick comprises the steps of simulating a hot spot area at the connecting position of the gate stick and a gate through software, manufacturing a wax mold, manufacturing a protruding structure in the hot spot area of the wax mold of the gate stick, manufacturing a shell, dewaxing, and then manufacturing the shell. The convex structure forms a small included angle structure at the gate stick shell; by utilizing the characteristic that the small included angle is easy to loosen when the mold shell is poured, the small included angle structure is prepared on the gate stick, the hot spot of the gate stick is increased, and the solidification time of molten metal at the position of the small included angle structure is shorter than the time of the gate during pouring, so that the purpose of feeding the gate is
