Description

Technical Field

[0001] The utility model relates to the technical field of punching and shearing dies, in particular to a punching and shearing die for die-casting products. Background Art

[0002] In stamping production, the die used for blanking is called a blanking die. The main task of the blanking die is to separate the materials. Under this premise, there are many ways to classify the blanking die. According to the nature of the process, the blanking die can be divided into blanking dies, punching dies, cutting dies, trimming dies, fine punching dies, etc.

[0003] The patent document with the prior art publication number CN219378624U provides an efficient punching die, including a base for supporting and fixing the punching die, a cutting assembly for conveniently cutting off the scraps in the middle of the punching die, and a demolding assembly for conveniently removing the forming die quickly in the middle of the punching die. The beneficial effect of the utility model is that a cutting assembly is arranged in the middle of the punching die, and each time the upper and lower dies are closed and punched, the scraps of the die will be cut off, and the cut scraps will also fall into the annular groove. When the punching is completed, the annular plate rises to recycle these scraps, which is convenient and quick, and the demolding assembly can quickly remove the formed die, thereby increasing the efficiency of die punching, thereby making the die efficiently produced and increasing production efficiency.

[0004] However, during the use of the existing product die-casting punching die, the raw material needs to be placed on the lower die, and then the upper die presses the raw material downward, and the upper die punches the raw material into a product through the lower die. During the punching, the raw material will produce friction and collision with the upper and lower dies. When the number of punching is too many, it will cause loss, resulting in a certain error in the punched product. When there is an error, only the upper and lower dies can be replaced, and it is impossible to replace them based on local loss, thereby increasing the production cost of the enterprise and also leading to the problem of a short service life of the punching die. For this reason, we propose a product die-casting punching die. Utility Model Content

[0024] In this embodiment, specifically, the installation assembly includes a base plate 1 and an installation port 2. The base plate 1 is fixedly connected to the bottom of the installation plate 3. The installation ports 2 are opened at the four corners of the top of the base plate 1. The mold can be installed by placing the base plate 1 in the installation position and then inserting the fixing accessories into the installation port 2 for tightening.

[0025] In the present embodiment, specifically, the limiting mechanism includes a limiting rod 8, a storage rod 9, a reset spring 10 and a fixing screw 12. The limiting rod 8 is fixedly connected to the top of the mounting plate 3. The top of the limiting rod 8 is movably connected to the storage rod 9. The outer sides of the limiting rod 8 and the storage rod 9 are movably connected to the reset spring 10. The top of the storage rod 9 is threadedly connected to the fixing screw 12. The storage rod 9 is fixedly connected to the top plate 11 by the fixing screw 12. When the stamping equipment pushes the upper mold 14 to move downward, the limiting rod 8 enters the storage rod 9, and the reset spring 10 is compressed at the same time. After the stamping is completed, the stamping equipment drives the upper mold 14 to reset through the mold handle 13, and the reset spring 10 drives the limiting rod 8 and the storage rod 9 to restore.

[0026] In the present embodiment, specifically, the pushing mechanism includes a pushing rod 401, a telescopic spring 402 and a mounting groove 403. The mounting groove 403 is arranged inside the lower mold 4. The mounting groove 403 is movably connected with the telescopic spring 402. The top of the telescopic spring 402 is fixedly connected with the pushing rod 401. When the product enters the mold groove 5, the pushing rod 401 squeezes the telescopic spring 402 to shrink into the mounting groove 403. After the stamping is completed, the reset spring 10 drives the limiting rod 8 and the storage rod 9 to restore. At this time, the telescopic spring 402 will reset and push the pushing rod 401, thereby pushing the product out.

At the same time, the reset spring 10 is compressed, and the upper template 15 and the lower template 6 will punch the raw material and punch the raw material into a product. At this time, the product will enter the die groove 5, and the push rod 401 squeezes the telescopic spring 402 to shrink into the installation groove 403. After the stamping is completed, the stamping equipment drives the upper die 14 to reset through the die handle 13. At the same time, the reset spring 10 drives the limit rod 8 and the storage rod 9 to recover. At this time, the telescopic spring 402 will reset and push the push rod 401, thereby pushing the product out. When the lower template 6 and the upper template 15 are worn out due to too many punching times, the staff can loosen the lower bolts 7 and the upper bolts 17. At this time, the lower template 6 can be removed from the mold groove 5, and the fixing plate 16 will be separated from the upper mold 14 to remove the upper template 15, and then the lower template 6 and the upper template 15 can be replaced and fixed with the lower bolts 7 and the upper bolts 17, so that the punching mold can be reset to its original accuracy, thus completing the use process of the utility model. The utility model has a simple structure and is safe and convenient to use.
