The first driving device is installed on the stamping machine. The first driving device is located above the pressing assembly 2, and the output end of the first driving device faces the pressing assembly 2 directly. The first driving device is a hydraulic cylinder. Four guide rails 11 are provided on the front of the mounting base 1. The number of the fixing assemblies 6 and the moving seats 7 is four respectively. The four moving seats 7 are respectively slidably installed on the corresponding guide rails 11.

In this embodiment, the third driving device 61 is a cylinder. After the die-cast product is placed on the positioning assembly 5, the second driving device drives the fixing assembly 6 to reset through the moving seat 7, and then the output end of the third driving device 61 retracts, and the connecting bar 62 drives the pressing block 63 to approach the front of the mounting seat 1, so as to press and fix the die-cast product. The pressing block 63 is specifically F2 hard glue.

The four positioning columns 53 are respectively located inside the four stop blocks 111; the profiling positioning block 54 is installed on the front of the top of the mounting seat 1, the profiling positioning block 54 is located above the positioning columns 53, and the profiling positioning block 54 is located between the two positioning columns 53. In this embodiment, through the positioning of the two first positioning bosses 51, the two second positioning bosses 52, the four positioning columns 53 and the profiling positioning block 54, the die-cast product can be accurately placed at the press-fitting position, so as to ensure that the mounting hole of the special-shaped water nozzle is adapted to the special-shaped water nozzle, which is beneficial to improving the press-fitting quality.

[0037] As Figures 1-3As shown, the reset component 3 includes a moving rod 31, an elastic member 32, and a blocking member 33. A top plate 12 is provided at the top of the mounting base 1.

The elastic member 32 is sleeved on the outer periphery of the moving rod 31. One end of the elastic member 32 abuts against the press-fitting component 2, and the other end of the elastic member 32 abuts against the top surface of the mounting base 1. In this embodiment, the numbers of the moving rod 31, the elastic member 32, and the blocking member 33 are two respectively. The elastic member 32 is a spring. The tops of the two moving rods 31 are respectively connected to the left and right ends of the press-fitting component 2. The two moving rods 31 can be movably mounted on the tops of the left and right ends of the top plate 12. The two blocking members 33 are located below the top plate 12. During operation, the output end of the first driving device extends to drive the press-fitting component 2 to press down until the press-fitting component 2 abuts against the limiting component 4, then the special-shaped water nozzle press-fitting is completed. Then, the output end of the first driving device retracts, and the press-fitting component 2 is pushed upward to reset under the elastic force of the elastic member 32. The moving rod 31 also moves upward accordingly until the blocking member 33 at the bottom of the moving rod 31 abuts against the bottom surface of the top plate 12, then the automatic reset is completed, which is convenient and fast.

[0038] As Figures 1-3 shown, the press-fitting component 2 includes a lower pressing plate 21, a lower pressing seat 22, and a placing seat 23. The lower pressing seat 22 is mounted on the bottom surface of the lower pressing plate 21. The top plate 12 is provided with an avoidance area 121. The placing seat 23 is mounted on the bottom surface of the lower pressing seat 22. The placing seat 23 is directly opposite to the avoidance area 121. The placing seat 23 is provided with a placing position 231 for placing the special-shaped water nozzle. The top of the moving rod 31 is connected to the end of the lower pressing seat 22. In this embodiment, the tops of the moving rods 31 are respectively connected to the bottoms of the left and right ends of the lower pressing seat 22. During operation, the special-shaped water nozzle is installed in the placing position 231 of the placing seat 23, and then the first driving device drives the lower pressing plate 21 to press down. The lower pressing plate 21 pushes the lower pressing seat 22 to press down. The moving rod 31 moves downward. The elastic member 32 is compressed. The placing seat 23 passes through the avoidance area 121 to press-fit the special-shaped water nozzle onto the die-cast product, which is convenient and fast.

[0039] As Figure 4As shown, the placement position 231 is provided with a positioning groove 2311 for positioning and clamping a special-shaped water nozzle. In this embodiment, the positioning groove 2311 is provided in the placement position 231, so that the special-shaped water nozzle can be quickly positioned and clamped in the placement position 231, which is convenient and fast and improves production efficiency.

[0040] As Figures 1-3 shown, the limiting component 4 includes limiting columns 41. The number of the limiting columns 41 is two. The two limiting columns 41 are installed on the top surface of the top plate 12, and the limiting columns 41 are provided with limiting steps 411. The bottom surface of the lower pressing plate 21 can abut against the top surface of the limiting columns 41, and the bottom surface of the lower pressing seat 22 can abut against the limiting steps 411. In this embodiment, by providing the two limiting columns 41 on the top surface of the top plate 12, and the two limiting columns 41 are located below the left and right ends of the lower pressing seat 22, the structural design of the two limiting columns 41 on the left and right can prevent the lower pressing component 2 from tilting after being limited and blocked by the limiting columns 41. When the lower pressing plate 21 pushes the lower pressing seat 22 down, the bottom surface of the lower pressing plate 21 abuts against the top surface of the limiting columns 41, and the bottom surface of the lower pressing seat 22 abuts against the limiting steps 411. Through the double-plane limiting and blocking structure, the blocking pressure on the top surface of the blocking column 41 is reduced, which is beneficial to improving the service life of the blocking column 41.
