Description

Technical Field

[0001] This utility model relates to the field of stamping demolding technology, specifically a stamping structure that facilitates demolding. Background Technology

[0002] Stamping is a manufacturing technology that uses dies and presses to apply pressure to metal sheets, causing them to undergo plastic deformation or separation, thereby obtaining workpieces of the required shape and size. In the production and processing of U-shaped parts, stamping machines and corresponding U-shaped stamping dies are mostly required.

[0003] The aforementioned device lacks a structure for rapid material removal from the stamping die during use. This makes it easy for the bent U-shaped part to get stuck on the upper die and difficult to remove when the U-shaped part is stamped. If the U-shaped part is manually removed from the upper die, the safety hazard will increase significantly after a person's hand enters the die. The stamping machine and die will threaten the personal safety of the operator. Based on the shortcomings of the existing technology, this utility model designs a stamping structure that facilitates demolding. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 A stamping structure for easy demolding includes a base plate 1, a second top plate 2 above the base plate 1, and a material ejection mechanism 3 below the second top plate 2 for quick removal of U-shaped parts. A limit rod 101 is fixedly connected to the upper surface of the base plate 1, and a lower stamping die 102 is fixedly connected to the upper surface of the base plate 1. A stamping groove 103 is provided on the lower stamping die 102, and a first top plate 104 slides and moves up and down in the stamping groove 103. Telescopic rods 105 are provided at the bottom of both ends of the first top plate 104, and ejector springs 106 are sleeved on the telescopic rods 105. The bottom end of the telescopic rods 105 is fixedly connected to the base plate 1, and the upper and lower ends of the ejector springs 106 are respectively fixedly connected to the opposite sides of the first top plate 104 and the base plate 1.

[0019] Please see Figure 3 A connecting plate 201 is fixedly connected to the upper surface of the second top plate 2. Limiting sleeves 202 are fixedly connected through both ends of the lower surface of the connecting plate 201. The limiting sleeves 202 are slidably sleeved on the limiting rod 101.

[0020] Please see Figure 4-5The ejection mechanism 3 includes an upper stamping die 301, an inner groove 302, an ejection rod 303, an ejection plate 304, a pull head 305, a push plate 306, and a spring 307. The upper stamping die 301 is fixedly connected to the lower surface of the second top plate 2. The inner groove 302 is formed inside the upper stamping die 301. The ejection rod 303 is slidably inserted into the inner groove 302. The ejection plate 304 is fixedly connected to the rear end of the ejection rod 303. The pull head 305 is fixedly connected to the front end of the ejection rod 303. The push plate 306... 06 is fixedly connected to the side wall of the ejector bar 303. The spring 307 is sleeved on the ejector bar 303. The upper stamping die 301 is slidably inserted into the stamping groove 103. The upper stamping die 301 is pressed down above the first top plate 104. The ejector bar 303 is slidably inserted into the upper stamping die 301. The ejector plate 304 is slidably connected to both sides of the upper stamping die 301. The push plate 306 is slidably connected to the inner groove 302. The two ends of the spring 307 are respectively connected to one end of the inner wall of the inner groove 302 and the push plate 306.

[0021] By setting up a material ejector bar 303, a material ejector plate 304, and a pulling head 305, the material ejector plate 304 is moved forward by the material ejector bar 303 and slides on the upper stamping die 301 to push the U-shaped part out of the bottom plate 1. By setting up an inner groove 302, a push plate 306, and a spring 307, the material ejector plate 304 is tractioned to slide on the upper stamping die 301 to push out the U-shaped part. After the pulling head 305 is released, the spring 307 can rebound to push the push plate 306 and the material ejector bar 303 to push the material ejector plate 304 backward to slide out of the upper stamping die 301 and reset to wait for the next part removal without affecting the next stamping.

[0022] Working principle: When a stamping structure that facilitates demolding is used, in the initial state, the lower stamping die 102 with a stamping groove 103 at the top is first set on the upper surface of the base plate 1. The second top plate 2 set above the base plate 1 is connected to the base plate 1 through the limiting rod 101 and the limiting sleeve 202. The upper stamping die 301 is set on the lower surface of the second top plate 2 to facilitate the stamping of U-shaped parts. The ejector rod 303 is inserted into the inner groove 302 opened on the upper stamping die 301. The ejector rod 303 has an ejector plate 304 and a pull head 305 at both ends. The ejector plate 304 is slidably connected to both sides of the upper stamping die 301 to facilitate the ejection of the U-shaped parts clamped on the upper stamping die 301 after stamping. When a U-shaped part needs to be ejected quickly and safely, firstly, after the upper stamping die 301 completes the stamping process of the U-shaped part and the workpiece is clamped on the upper stamping die 301, the pull head 305 is hooked and the ejector rod 303 is pulled forward. The forward-moving ejector rod 303 drives the ejector plate 304 and the push plate 306 to move forward as well. The forward-moving ejector plate 304 removes the U-shaped part stuck on the surface of the upper stamping die 301, while the push plate 306 also compresses the spring 307. After the U-shaped part is removed, the pull head 305 is released, causing the spring 307 to rebound and push the push plate 306 to reset. The reset push plate 306 pushes the ejector rod 303 to reset as well, and drives the ejector plate 304 to slide out of the upper stamping die 301 to wait for the next stamping. This device facilitates the quick and safe ejection of U-shaped parts.
