DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention:

[0016] As shown in the figure, a device for processing tooth-shaped inserts of automobile staples is used to process Figure 1The illustrated staple 1 has two sets of tooth arrays 11, each with multiple teeth 111. The two sets of tooth arrays 11 are arranged in mirror-image symmetry, and two staple slots 12 are located before the ends of the two sets of tooth arrays 11. The lower end 13 of the staple 1 is conical. The device of the utility model includes a tooth-shaped mold 2 and an insert 3. The insert 3 includes a left insert 31 and a right insert 32. The left insert 31 and the right insert 32 have identical structures and are arranged in mirror-image symmetry. The tooth-shaped mold 2 is divided into a left mold 21 and a right mold 22. The left mold 21 is provided with an insert slot 1 23, and the right mold 22 is provided with an insert slot 24. When the left mold 21 and the right mold 22 are combined in mirror-image symmetry, two tooth array cavities 25 are formed. The insert slot 1 23 and the insert slot 24 are located on either side of the tooth array cavity 25. The bottoms of the two tooth array cavities 25 form a conical groove 26, which mates with the lower end 13. The two tooth array cavities 25 correspond to the two sets of tooth arrays 11. The tooth array cavities 25 are provided with the same number of tooth cavities 251 as the teeth 111. The cross-section of the tooth array cavities 25 is an arc-shaped shape that is smaller than a semicircle. The tooth array 11, after processing the staple raw material, is formed into an integral piece, making it more secure after secondary assembly than existing single teeth. The right insert 32 has a concave groove 321 at one end that matches the staple groove 12, and a trapezoidal insert tail 322 at the other end. The middle of the right insert 32 is provided with a protrusion 1 323 and a protrusion 2 324 outward. These protrusions 1 323 and 324 contribute to the firmness of the right insert 32 during processing. A circular step 325 is provided on the outside of the protrusion 2 324 to facilitate the removal and insertion of the right insert 32.

[0017] During use, the left and right inserts 31 and 32 are not yet placed in the insert slots 1 and 2, respectively. At this point, the top of the staple 1 has already been machined, and the lower portion of the staple 1 is a rectangular parallelepiped. The rectangular parallelepiped is placed in the gap between the two tooth array cavities 25. The device is then energized, rotating the raw material during electrocorrosion to cast two sets of tooth arrays 11. After the two sets of tooth arrays 11 are cast, the left insert 31 is placed in the insert slot 1, respectively, and the right insert 32 is placed in the insert slot 2, respectively, and energized to complete the machining of the two staple slots 12. The protrusions 1 and 2, respectively, 323 and 324, ensure the stability of the left and right inserts 31 and 32 during machining. After the staple slots 12 are machined, the left and right molds 21 and 22 are separated, demolding is completed, and the staples can be removed.

[0018] The above embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
