Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a die cavity adjustment type stamping die. Background Art

[0002] Stamping dies are special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform it, thereby obtaining the desired parts.

[0003] The Chinese patent publication number is CN220574524U. It discloses a stamping die with a variable die cavity, which includes a lower die, a die cavity is provided in the lower die, and an adjustment component is provided in the die cavity, and the adjustment component includes adjustment blocks that are relatively distributed. The knob is rotated to rotate the screw rod, and the screw rod cooperates with the thread groove, which then drives the adjustment block to move horizontally, and the horizontal block slides along the slide groove to adjust the spacing between the two adjustment blocks to achieve the change and adjustment of the die cavity size. The scheme has a novel structure, can achieve the adjustment of the die cavity size, and improves practicality.

[0004] With regard to the above-mentioned related technologies, the device has some shortcomings. In actual use, the screw, as a driving structure, does not have any positioning mechanism and has low stability. During the stamping process of parts, the position of the adjustment block is easily displaced, which reduces the stability and reliability of the mold during the stamping process of parts. Therefore, it is necessary to provide a cavity adjustment stamping mold to solve the above-mentioned technical problems. Utility Model Content

[0027] See also Figure 1-4 , an embodiment provided by the utility model:

[0028] A die cavity adjustment type stamping die, comprising:

[0029] A lower mold 1, a mold cavity 2 is arranged on the top of the lower mold 1, threaded barrels 12 are rotatably mounted on both sides of the lower mold 1, and the opposite ends of the two threaded barrels 12 penetrate the side of the lower mold 1 and contact the inner wall of the mold cavity 2, the two threaded barrels 12 are threadedly connected with threaded rods 8, the opposite ends of the two threaded rods 8 are fixedly mounted with adjustment blocks 3, and the adjustment blocks 3 are slidably connected with the inner wall of the mold cavity 2;

[0030] Transmission gears 6 are fixedly mounted on the outer walls of the opposite ends of the two threaded barrels 12. Gear plates 10 are rotatably mounted below the threaded barrels 12 on both sides of the lower mold 1, and the gear plates 10 are meshed with the transmission gears 6. A positioning mechanism is provided on the gear plates 10.

[0031] Horizontal blocks 4 are installed above the opposite sides of the two adjustment blocks 3 , and limiting grooves 5 are provided above both sides of the inner wall of the mold cavity 2 , and the limiting grooves 5 are slidably connected to the horizontal blocks 4 .

[0032] In one of the embodiments, the positioning mechanism includes a fixing hole 18, and the fixing hole 18 is opened above one side of the gear plate 10, a slide groove 15 is opened on the upper side of the inner wall of the fixing hole 18, a slide rod 17 is fixedly installed inside the slide groove 15, a slider 13 is sleeved on the outer wall of the slide rod 17, and the slider 13 is slidably connected to the slide groove 15, a spring 16 is sleeved on the outer wall of the slide rod 17 on one side of the slider 13, a positioning rod 7 is fixedly installed at the bottom of the slider 13, and the positioning rod 7 is slidably connected to the fixing hole 18, a handle 9 is fixedly installed at one end of the positioning rod 7, a plurality of positioning grooves 11 are opened on both sides of the lower mold 1, and the positioning grooves 11 are clamped with the positioning rod 7, thereby realizing the self-locking function of the adjustment structure of the adjustment block 3.

[0033] In one of the preferred embodiments, a plurality of anti-skid rings are sleeved on the outer wall of the handle 9. The anti-skid rings can increase the friction of the handle surface, making it easier for the operator to hold it during use, thereby improving the stability and safety of the operation.

[0034] In one of the embodiments, the lower mold 1 and the mold cavity 2 are an integrally formed structure, and the integrally formed structure can optimize the performance of the stamping mold, improve its reliability, precision and production efficiency, thereby bringing better processing effects and economic benefits.

[0035] In one preferred embodiment, a sliding hole matched with the sliding rod 17 is opened on one side of the sliding block 13, and the sliding block 13 is slidably connected with the sliding rod 17 through the sliding hole opened on one side.

[0036] The working principle of the utility model is as follows: the parts not involved in the device are the same as the prior art or can be implemented by the prior art. When the size of the cavity 2 needs to be adjusted during the use of the lower mold 1, the staff can directly hold the handle 9 and pull the positioning rod 7 to move. The movement of the positioning rod 7 drives the slider 13 to slide on the outer wall of the slide rod 17 and squeeze the spring 14. The movement of the positioning rod 7 will disengage from the inside of the positioning groove 11 at the corresponding position. After the gear plate 10 loses the clamping limit between the positioning rod 7 and the positioning groove 11, the gear plate 10 can be directly driven by the handle 9 to rotate. Through the meshing of the gear plate 10 and the transmission gear 6, the transmission gear 6 drives the threaded barrel 12 to rotate. Through the threaded transmission of the threaded barrel 12 and the threaded rod 8, and the sliding relationship between the adjustment block 3 and the cavity 2, The adjusting block 3 stably moves laterally inside the die cavity 2. After the position of the adjusting block 3 is determined, the limit on the handle 9 is released. Under the elastic action of the spring 14, the positioning rod 7 will be driven by the slider 13 to directly snap into the corresponding positioning groove 11. The position of the gear plate 10 is limited by the clamping connection between the positioning rod 7 and the positioning groove 11. The gear plate 10 will directly lock the transmission gear 6. After the transmission gear 6 is limited, the threaded barrel 12 can ensure the stability of the position of the adjusting block 3 through the threaded transmission between the threaded rod 8, so that in the subsequent workpiece stamping process, the position of the adjusting block 3 is not easy to shift, thereby improving the stability and reliability of the mold during the parts stamping process. In addition, the adjustment structure of the adjusting block 3 is simple to operate, which is convenient for people to quickly change the size of the die cavity 2 to adapt to the stamping forming requirements of different workpieces, and is highly practical.

[0037] During the lateral movement of the adjustment block 3 inside the mold cavity 2, the horizontal block 4 will be driven to slide on the limit groove 5, which can further improve the stability of the lateral movement of the adjustment block 3. At the same time, the horizontal block 4 can block the unused area inside the mold cavity 2, facilitating the stamping of the workpiece.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
