When the blowing seat 7 is arranged outside the mold, the air inlet pipe can be directly connected to the blowing hole 8 in the blowing seat 7, so the blowing hole 8 can be arranged as a horizontal straight hole, and the bottom of the blowing seat 7 can be connected to the side core-pulling slide seat 3 through a stud 9, and people can also adjust the blowing angle of the blowing hole 8 by rotating the blowing seat 7 at a small angle, which is convenient to adjust.

[0019] Furthermore, a positioning groove 10 is formed on the fixed mold plate 1 and / or the movable mold plate 2, and an air inlet hole 11 is opened in the positioning groove 10. One end of the air inlet hole 11 is connected to the air inlet pipe, and the air inlet pipe is connected to the air source. A blowing seat 7 is arranged in the positioning groove 10, and the blowing seat 7 is fixed to the fixed mold plate 1 or the movable mold plate 2 through a fastener. A T-shaped blowing hole 8 is formed in the blowing seat 7, and the bottom of the T-shaped blowing hole 8 is communicated with one end of the air inlet hole 11. One end of the upper part of the T-shaped blowing hole 8 corresponds to the side core pulling rod 5 or the thin mold iron 6, and a plug 12 is arranged in the other end of the upper part of the blowing hole 8.
