[0032] Please refer to Figures 1 to 3 The embodiment of the utility model provides a linear and rotary composite automatic blowing system for a trimming machine, which is used for blowing the aluminum slag formed by the trimming machine 1. The trimming machine 1 comprises a lower die seat 11 and an upper die seat 12 arranged along a first direction. Guide columns 14 are arranged at each corner of the top surface of the lower die seat 11.

After the upper die seat 12 and the lower die seat 11 are combined, the excess corner material of the die casting can be removed. The blowing system is detachably installed on the two side surfaces along a second direction and the two side surfaces along a third direction of the lower die seat 11. The first direction is the vertical direction in Figure 1 , the second direction is the front-rear direction in Figure 1 , and the third direction is the left-right direction in Figure 1 . The blowing system comprises:

The connecting air nozzle 52 is in communication with the gas outlet of the gas source. A plurality of branch air pipes 53 are uniformly arranged at the bottom end of the main air pipe 51 along the axis extension direction. Each branch air pipe 53 extends downward and inclines away from the connecting air nozzle 52. A nozzle 54 is installed at the end of each branch air pipe 53 away from the main air pipe 51.

The rotary disk of the rotary slide 3 is provided with a connecting assembly 4, and the connecting assembly 4 is connected to the end of the main air pipe 51 near the connecting air nozzle 52. The rotary slide 3 drives the connecting assembly 4 and the air flow injection assembly 5 to rotate around the first axis, driving the nozzle 54 to move between the lower die base 11 and the upper die base 12;
