[0069] When this application embodiment is used,

[0070] Preparation:

[0071] Check that all components of the equipment are securely installed, including whether the bottom mold 4 is securely installed by the mounting block 26 at the bottom and the mounting groove 25 at the top of the supporting base plate 6, and whether the cutting head 27 is securely installed by the mounting block 23 at the top of the mounting base 16 and the mounting groove 22 at the bottom of the movable plate 8. Check that the finished product box 10 and the waste box 11 are placed in the cavity 1 28 and cavity 2 17 respectively, and that the doors on one side of the machine body 1 corresponding to cavity 1 28 and cavity 2 17 can be opened and closed normally. Confirm that switch 1 19 and switch 2 21 are in the closed state and are undamaged. Place the aluminum alloy die-casting part to be processed on the bottom mold 4, ensuring that the die-casting part is in the correct position.

[0072] Start the device:

[0073] The operator simultaneously presses switch 19 and switch 21 on one side of the top support plate 6 of the worktable 12, at which point the equipment starts.

[0074] Trimming operation:

[0075] The cylinder 15 at the top center of the top plate 14 starts working, and the output end of the cylinder 15 pushes the movable plate 8 downward. Because the guide holes 9 at the four corners of the movable plate 8 cooperate with the guide rods 7 at the four corners of the top of the supporting base plate 6, the guide rods 7 ensure that the movable plate 8 moves downward smoothly. As the movable plate 8 descends, the trimming head 27 installed at the bottom of the movable plate 8 gradually approaches the aluminum alloy die-casting part to trim its edges. During this process, the push rod 18 at the bottom of the movable plate 8 also descends. The length of the push rod 18 is greater than the height of the trimming head 27, and the push rod 18 will first contact the waste material at the top of the waste guide trough 20 and squeeze the waste material.

[0076] Waste and finished products are collected separately:

[0077] The finished product generated during the trimming process passes through a hole 5 in the center of the bottom mold 4, then through the material discharge channel 2 on the lower worktable 12 and the supporting base plate 6, and finally falls into the finished product box 10 in the cavity 28 at the center of the machine body 1. The waste generated during trimming is squeezed by the trimming head 27 into the downward-sloping waste guide groove 20 on the outside of the bottom mold 4. The waste slides down the waste guide groove 20 to the waste outlet 3 on the worktable 12, and enters the cavity 17 inside the machine body 1 through the waste outlet 3, finally falling into the waste box 11 in the cavity 17. When the movable plate 8 rises, the spring 24 on the inner side of the waste guide groove 20 returns to its original deformation and vibrates, causing the waste remaining at the top of the waste guide groove 20 to fall quickly into the waste box 11.

[0078] Complete the trimming:

[0079] After the trimming is completed, the output end of the cylinder 15 drives the movable plate 8 to rise, causing the trimming head 27 and the ejector rod 18 to leave the bottom mold 4 and the waste guide groove 20 and return to the initial position.

[0080] Remove finished products and waste materials:

[0081] Open the doors on one side of the machine body 1 corresponding to the positions of cavity 28 and cavity 17, take out the finished aluminum alloy die-cast parts from the finished product box 10, and take out the collected waste from the waste box 11 for further processing.

[0082] Equipment maintenance:

[0083] Regularly inspect the wear condition of each component of the equipment, such as the wear of the cutting head 27. If the wear is severe, the cutting head 27 can be replaced by disassembling the mounting base 16. Check the fit between the guide rod 7 and the guide through hole 9 to ensure smooth movement of the movable plate 8. Clean the waste guide chute 20 and the discharge channel 2 to prevent waste accumulation from affecting the normal operation of the equipment. Perform necessary lubrication and maintenance on the equipment to extend its service life.

[0084] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
