Technical Field

[0001] The utility model relates to the technical field of die casting nozzle stamping, in particular to a die casting nozzle stamping die. Background Art

[0002] A product often needs to go through multiple processes such as die-casting, stamping, and polishing before it can be sold and used. In the die-casting manufacturing process, the process of removing the sprue is required after the product is formed. When removing the sprue of a die-casting, stamping is the fastest and most effective way to remove the sprue. With the development of modern technology, die-casting stamping dies for removing sprues are used more and more frequently, and the functions of the upper end are gradually improved, so that they can better meet the needs of use.

[0003] In view of this, Chinese patent number CN219786214U proposes a die-casting nozzle stamping die. In the utility model, the tubular die-casting placed on the cutting die can be centered and clamped from the inside by means of the threaded rod, scissor frame and clamping block, so that the nozzle cutting effect of the tubular die-casting is better and the work efficiency is improved. However, the stamping method for the mold in the above technical scheme is still top-down stamping. For the workpiece, especially the nozzle at the upper end of the tubular workpiece, the distribution area may be relatively large. The top-down stamping method limits the area of ​​the nozzle and cannot completely remove the nozzle, thereby reducing the use effect of the device. Utility Model Content

[0011] In one example, a rotating handle is rotatably provided on one side of the lower module, and one end of the double-threaded screw passes through the inner wall of the lower module and is fixedly connected to one end of the rotating handle, and protective pads are fixedly provided on the inner walls of the two U-shaped clamps.

[0023] In order to more clearly illustrate the overall concept of the utility model, a detailed description is given below in the form of examples in conjunction with the accompanying drawings.

[0024] The examples are as follows:

[0025] The utility model provides Figure 1-5 A die casting nozzle stamping die shown includes a lower module 1 and an upper module 2, and a transverse stamping and scraping nozzle mechanism is provided at the upper end of the upper module 2;

[0026] The transverse stamping wiper mechanism includes four first hydraulic rods 3 fixed on both sides of the bottom of the upper module 2, two lifting modules 4 are fixedly arranged at one end of the four first hydraulic rods 3, a second hydraulic rod 5 is fixedly arranged on one side of the two lifting modules 4, a stamping module 6 is fixedly arranged at one end of the two second hydraulic rods 5, a shaping module 7 is fixedly arranged at the middle position of the two stamping modules 6 at the bottom of the upper module 2, an electric telescopic rod 8 is fixedly arranged on the upper end of one side of the two lifting modules 4, a U-shaped bracket 9 is fixedly arranged on the output end of the two electric telescopic rods 8, and a scraper 10 is fixedly arranged on the inner wall of the two U-shaped brackets 9. When the stamping module 6 stamps the tubular casting, the U-shaped bracket 9 is moved to the rear side of the stamping module 6 by the electric telescopic rod 8 so that it does not contact the tubular casting to prevent the casting from being scratched during the stamping process, and when the stamping module 6 wraps the casting, a certain position is reserved at its lower end to prevent the scraper 10 from contacting the casting when the U-shaped bracket 9 moves later;

[0027] Furthermore, connection holes 11 are provided at the four corners of the bottom of the upper module 2 , and limiting rods 12 are fixedly provided at the four corners of the top of the lower module 1 .

[0028] The outer walls of the four limit rods 12 are respectively connected with the inner walls of the four connecting holes 11, and a positioning groove 13 is fixedly provided at the middle position of the top of the lower module 1. The limit rods 12 are connected with the connecting holes 11 so that the upper module 2 is not easy to deviate during the pressure drop process, ensuring that the stamping module 6 and the shaping module are dropped in the center.

[0029] Furthermore, the convenient positioning and clamping mechanism includes adjustment slots 14 provided on both sides of the inner wall of the positioning slot 13 , the inner walls of the two adjustment slots 14 are interspersed with movable brackets 15 , and one end of the two movable brackets 15 is fixed with a U-shaped clamp 16 .

[0030] The lower ends of the two movable brackets 15 are each provided with a screw hole 17 , and the lower end of the inner wall of the lower module 1 is rotatably provided with a double-threaded screw rod 18 , and the outer walls at both ends of the double-threaded screw rod 18 are respectively threadedly connected with the inner walls of the two screw holes 17 .

[0031] A rotating handle 19 is rotatably provided on one side of the lower module 1, and one end of the double-threaded screw 18 passes through the inner wall of the lower module 1 and is fixedly connected to one end of the rotating handle 19. The inner walls of the two U-shaped clamps 16 are fixedly provided with protective pads 20. When the tubular casting is clamped by the U-shaped clamp 16, the protective pad 20 at the upper end of the inner wall contacts it to prevent the clamp from wearing the casting. At the same time, when the double-threaded screw 18 moves with the clamp, the center point between the two clamps is always kept overlapping with the inner center point of the positioning groove 13.

[0032] Working principle: When using the die casting sprue stamping die in the present design, firstly, the upper module 2 needs to be connected through the limit rod 12 and the connecting hole 11 at its upper end, and connected to the upper end of the upper module 2 through an external driving device so that it can be pressure-dropped. When in use, the tubular casting is placed in the positioning groove 13, clamped by a clamping mechanism, and then the upper module 2 is pressure-dropped so that the shaping module 7 is inserted into the interior of the tubular casting, and then the first hydraulic rod 3 is started to adjust the height of the stamping module 6 so that it is wrapped around the upper end of the casting to prevent the stamping module 6 from squeezing the upper end of the lower module 1 and causing damage to the equipment. After the stamping module 6 stamps and wraps the casting, the shaping module 7 is kept constant so that it is not easily deformed due to excessive stamping strength, and then the electric telescopic rod 8 is started to move the U-shaped bracket 9 to the lower edge of the casting to make it upward The scraper 10 at the end contacts its surface, and is retracted again by the first hydraulic rod 3, thereby moving upward with the stamping module 6 and the scraper 10, and the scraper 10 scrapes the surface of the casting to scrape off the water outlet on its surface, thereby achieving the purpose of completely removing the water outlet and improving the use effect of the device. When placing the casting, it is inserted into the positioning groove 13 and then the rotating handle 19 on the side of the lower module 1 is rotated to rotate the double-threaded screw 18, and the two mobile brackets 15 are threadedly connected with the screw hole 17 to move closer to or away from each other in the adjustment groove 14, so that the U-shaped clamps 16 at the upper ends of the two mobile brackets 15 clamp the lower end of the tubular casting to fix it in the positioning groove 13 and ensure its central positioning, which is convenient for the stamping module 6 and the shaping module 7 at the upper end to be connected with it, and no manual adjustment by the staff is required, thereby improving the convenience of using the device.
