[0017] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0018] Example

[0019] Please see Figures 1-4 This utility model discloses a stamping die assembly for piercing holes in an automotive radiator grille, comprising a protective box 1, a collection box 4, two sets of base supports 7, and two sets of limiting rods 9. A servo motor 2 is fixedly mounted on the top of the protective box 1. Threaded rods 3 are threadedly connected to both sides of the protective box 1. Extension plates 5 are integrally fixedly connected to both sides of the collection box 4, with the tops of the extension plates 5 aligned with the tops of the collection box 4. V-shaped locking blocks 6 are integrally connected to the bottom ends of both sets of extension plates 5. The two sets of base supports 7 are symmetrically fixedly connected to the lower front side of the protective box 1. V-shaped slots 8 are provided at the top of each set of base supports 7. The collection box 4 is mounted on the base supports 7 through the cooperation of the V-shaped locking blocks 6 and the V-shaped slots 8. Connecting shafts 12 are integrally connected to the top sides of both sets of limiting rods 9. Mounting grooves 1 are provided in the middle of the sides of both sets of extension plates 5. 1. Two sets of limiting rods 9 are symmetrically rotated and installed on two sets of extension plates 5 through the cooperation of connecting shaft 12 and mounting groove 11. Limiting grooves 10 are opened on the outer side of both sets of base supports 7. The limiting grooves 10 are located directly below the mounting groove 11. The two sets of limiting rods 9 are respectively locked in the two sets of limiting grooves 10. In use, when installing the collection box 4, the cooperation of V-shaped locking block 6 and V-shaped locking groove 8 can guide the installation of the collection box 4, so that the collection box 4 can be smoothly placed on the base support 7. After the collection box 4 is installed, the limiting rods 9 are locked into the limiting grooves 10. Through the cooperation of the limiting rods 9 and the limiting grooves 10, the collection box 4 is limited to ensure the stability of the installation of the collection box 4, thereby making the installation of the collection box 4 more convenient and improving convenience.

[0020] Both sets of limiting rods 9 have a pull ring 13 integrally connected to the end away from the mounting groove 11. By setting the pull ring 13, when the collection box 4 is removed, by holding the pull ring 13, the limiting rod 9 is rotated outward, so that the limiting rod 9 is disengaged from the limiting groove 10 and rotates to the top of the extension plate 5. Thus, the collection box 4 can be lifted off the base 7 and taken off for carrying through the limiting groove 10. This makes it more convenient for the limiting rod 9 to rotate and also makes it easier to pick up and put down the collection box 4 for carrying.

[0021] The limiting rod 9 and the mounting groove 11 are in clearance fit, while the limiting rod 9 and the limiting groove 10 are in interference fit. The clearance fit between the limiting rod 9 and the mounting groove 11 makes the limiting rod 9 rotate more smoothly on the extension plate 5, and the interference fit between the limiting rod 9 and the limiting groove 10 makes the limiting rod 9 fit more tightly into the limiting groove 10, preventing the limiting rod 9 from coming out of the limiting groove 10 on its own.

[0022] Both sets of limiting grooves 10 have flared chamfers 14 on their outer sides; by setting the flared chamfers 14, when the limiting rod 9 is inserted into the limiting groove 10, it plays a guiding role, making it easier for the limiting rod 9 to be inserted into the limiting groove 10.

[0023] This utility model discloses a stamping die assembly for piercing holes in an automotive radiator grille. Its working principle is as follows: During installation of the collection box 4, by holding the pull ring 13 and lifting the collection box 4, the limiting rod 9 is vertically positioned above the extension plate 5. Through the cooperation of the V-shaped locking block 6 and the V-shaped locking groove 8, the installation of the collection box 4 is guided, smoothly placing the collection box 4 onto the base 7. After installation, the collection box 4 is positioned so that it abuts against the front of the protective box 1, thereby causing the limiting rod 9 to... Once aligned with the limiting groove 10, the limiting rod 9 can be rotated downwards via the pull ring 13 to engage with the limiting rod 9 in the limiting groove 10. Guided by the flared chamfer 14, the limiting rod 9 is more easily engaged. The cooperation between the limiting rod 9 and the limiting groove 10 limits the collection box 4, ensuring its stable installation. When removing the collection box 4, hold the pull ring 13 to rotate the limiting rod 9 out of the limiting groove 10, and then lift the collection box 4 off the base 7 to remove it.
