[0035] After the injection molding of the mold 4 is completed, the mold 4 needs to be cooled. The existing air cooling blowing direction is too few, and the blowing direction needs to be increased to improve the heat dissipation efficiency. The specific operation is as follows:

[0036] The starting motor 5102 drives the first rotating rod 5106 to rotate, drives the first rotating disk 5107 fixedly connected to the upper end of the first rotating rod 5106 to rotate, drives the first rotating disk 5107 fixedly connected to the first rotating disk 5107 to rotate, so that the guide hole 5109 and the second guide rod 5114 inside the guide hole 5109 rotate, and then drives the first guide rod 5112 to rotate, the appearance structure of the first guide groove 5110 is arc-shaped, and the arc direction of the first guide groove 5110 is opposite to the direction of the second guide groove 5111, and the appearance structure of the second guide groove 5111 is arc-shaped, so that the first guide rod 5112 moves inward and outward along the trajectory of the guide hole 5109 The air pushing plate 5113 can rotate inward and outward to increase the blowing range, and when the air pushing plate 5113 moves inward and outward, it drives the pull rod 5205 connected to the outer side above the air pushing plate 5113 to move, so that the third guide rod 5206 moves. When the third guide rod 5206 moves to the hypotenuse of the third guide groove 5204, the third guide rod 5206 drives the pull rod 5205 to move up and down, so that the air pushing plate 5113 can rotate, thereby increasing the blowing range and achieving better heat dissipation effect.

[0037] When the injection molding machine 3 performs injection molding on the mold 4, the air inside the mold 4 is not completely exhausted, which will cause bubbles to form inside the mold 4 during cooling. The bubbles need to be quickly exhausted. The specific operation is as follows:

[0038] When the second guide rod 5114 moves, it drives the second push rod 608 and the elastic rubber pad 610 arranged on the inner side of the third groove 609 to move inward and outward, drives the first push rod 607 to move, and makes the fourth guide rod 606 move on the inner side of the fourth guide groove 603. Because the appearance structure of the fourth guide groove 603 is bent, and the vertex of the fourth guide groove 603 at the bending point close to the mold 4 is higher than the vertex of the fourth guide groove 603 at the bending point away from the mold 4, the fourth guide rod 606 moves upward along the trajectory of the fourth guide groove 603, drives the first push rod 607 and the second push rod 608 to move upward, so that the knocking plate 611 will rotate to knock on the mold 4 from bottom to top, so that the bubbles can rise and be discharged from the exhaust port, thereby achieving the purpose of rapid discharge of bubbles.

[0039] When designing the first guide groove 5110 and the second guide groove 5111, they can be set according to the position of the exhaust hole of the mold 4. When the air pusher plate 5113 moves inward, it is not aimed at the position of the exhaust hole, but at the main body of the mold 4, so that the air flow hits the mold 4 and moves outward. At this time, the pressure outside the mold 4 is small, and the bubbles inside the exhaust hole can be discharged more easily.
