Description

Technical Field

[0001] This utility model relates to the field of automatic demolding technology, specifically an automatic demolding device for forgings with inclined guides. Background Technology

[0002] Forging demolding is a crucial step in the forging production process. It refers to the process of separating and removing the forging from the mold cavity after the metal billet has undergone plastic deformation under pressure or impact within a mold (usually including an upper die, lower die, or a concave die and a convex die) to form a forging that conforms to the designed shape and size. An automatic forging demolding device with inclined guides is an automated device specifically designed for forging production. Its core function is to achieve efficient, smooth, and damage-free automatic separation and removal of the forging from the mold cavity after it has been formed, through the coordinated action of the inclined guide structure and the automated drive and control system.

[0003] Existing publicly available technical solution CN210789085U discloses an automatic rotary unloading device for forging production, including a bearing plate. Support legs are fixedly connected to the four corners of the bottom of the bearing plate. An inverted L-shaped support frame is fixedly connected to the bearing plate. A hydraulic press is fixedly connected to the side of the support frame near the bearing plate. A hydraulic telescopic rod is connected to the output end of the hydraulic press. A connecting plate is fixedly connected to the end of the hydraulic telescopic rod away from the hydraulic press. A pressure block is fixedly connected to the side wall of the connecting plate away from the hydraulic telescopic rod. A connecting groove is formed on the bearing plate, and a mold is fixedly connected in the connecting groove. A linkage mechanism is connected to the bearing plate, including a fixed plate and a threaded shaft. This utility model can automatically demold and push the forging to a designated position using the power of the hydraulic press, eliminating the need for manual operation, saving manpower, improving efficiency, and preventing workers from contacting dangerous areas, thus avoiding dangers such as high-temperature burns and protecting worker safety. However, when implementing the existing technical solution, if the forging is pushed directly to the discharge port after demolding and then stored in the box, the forging may accumulate at the discharge port and be unable to slide down due to its own weight, which will affect production efficiency.

[0005] Given that in the existing technology, when forgings are directly pushed to the discharge port after demolding and then stored in the box, the forgings may accumulate at the discharge port and be unable to slide down due to their own weight, which affects production efficiency.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model activates a hydraulic cylinder, which in turn moves the first connecting column downwards, causing the pressure block to press down, the third connecting block to move downwards, and the first top column to move downwards. At this time, the return spring deforms, pulling the third limit block downwards, thus moving the second top column downwards, which in turn moves the ejector block welded to the upper end of the second top column downwards. When the ejector block contacts the second limit block, it is blocked and stops moving downwards. At this time, the first top column continues to move downwards until the pressure block contacts the ejector block. At this time, the forging blank deforms, causing the power output end of the hydraulic cylinder to rise, which in turn causes the pressure block to detach from the forging. At this time, the third connecting block also rises, which in turn causes the first top column to rise. When the upper end of the first top column contacts the ejector block, it pushes it upwards, which in turn pushes the forging upwards until it is demolded.

The first gear and the second gear mesh with each other, and the rotation of the second gear drives the first lead screw to rotate. Therefore, the first push rod can push the inclined plate to move.

[0016] 3. This utility model starts the motor, the second lead screw rotates, driving the second push rod to move horizontally until the forging is pushed to the inclined plate. The forging slides down the inclined plate in an orderly manner into the storage box. The forging is buffered when it passes the rubber sheet to prevent damage. Attached Figure Description

[0019] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments. Example 1

[0022] Please see Figure 1 - Figure 5 This is the first embodiment of the present utility model. This embodiment provides an automatic demolding device for forgings with inclined guide, including a worktable 1, a hydraulic cylinder 2, a storage box 3, a pressing component 4, an ejection component 5, a feeding component 6, and a pushing component 7; Hydraulic cylinder 2 is located behind workbench 1; storage box 3 is located in front of workbench 1; pressing component 4 is installed above hydraulic cylinder 2; ejection component 5 is installed inside workbench 1; feeding component 6 is located to the right of ejection component 5; and pushing component 7 is located to the left of workbench 1.

[0023] Specifically, the pressing component 4 includes: a first connecting post 401 and a first connecting block 402; the first connecting post 401 is keyed to the power output end of the hydraulic cylinder 2; and the first connecting block 402 is welded to the surface of the first connecting post 401.

[0024] Furthermore, the first connecting post 401 moves downward, thus causing the first connecting block 402 to move downward as well.

[0025] Specifically, the pressing component 4 also includes: a second connecting block 403, a first limiting block 404 and a pressing block 405; a second connecting block 403 welded to one side of the first connecting block 402; a first limiting block 404 welded to the lower end of the other side of the second connecting block 403; and a pressing block 405 disposed at the lower end of the first limiting block 404.

[0026] Furthermore, the second connecting block 403 moves downward, which in turn causes the pressure block 405 to press down.

[0027] Specifically, the ejector assembly 5 includes: a third connecting block 501 and a first ejector post 502; a third connecting block 501 connected to the middle of the lower end of the second connecting block 403; the third connecting block 501 is L-shaped; and a first ejector post 502 welded to the upper side of the other end of the third connecting block 501.

[0028] Furthermore, the third connecting block 501 moves downward, which in turn causes the first top column 502 to move downward.

[0029] When in use, the first connecting block 402 moves down, at which time the second connecting block 403 moves down, which in turn drives the pressure block 405 to press down. When the second connecting block 403 moves down, it drives the third connecting block 501 to move down, which in turn drives the first top column 502 to move down.

[0030] In summary, this utility model activates the hydraulic cylinder 2, which in turn moves the first connecting column 401 downward, causing the pressure block 405 to press down, the third connecting block 501 downward, and the first top column 502 downward. At this time, the return spring 505 deforms, pulling the third limiting block 506 downward, thus moving the second top column 503 downward, and consequently the ejector block 507 welded to the upper end of the second top column 503 downward. When the ejector block 507 contacts the second limiting block 504, it is blocked and stops moving downward. At this time, the first top column 502 continues to move downward until the pressure block 405 contacts the ejector block 507. At this time, the forging blank deforms, causing the power output end of the hydraulic cylinder 2 to rise, thereby causing the pressure block 405 to detach from the forging. At this time, the third connecting block 501 also rises, thereby causing the first top column 502 to rise. When the upper end of the first top column 502 contacts the ejector block 507, it pushes it upward, thereby pushing the forging upward until it is demolded. Example 2

[0031] Please see Figure 1 - Figure 5This is the second embodiment of the present utility model.

[0032] Specifically, the ejection assembly 5 also includes: a second ejector post 503, an ejection block 507, a third limiting block 506, a second limiting block 504, and a return spring 505; a second ejector post 503 disposed inside the first ejector post 502; an ejection block 507 welded to the upper end of the second ejector post 503; a third limiting block 506 installed at the lower end of the second ejector post 503; a second limiting block 504 slidably connected to the surface of the first ejector post 502; and a return spring 505 connected to the lower end of the interior of the first ejector post 502.

[0033] Furthermore, the return spring 505 deforms, pulling the third limit block 506 downward, which in turn drives the second top post 503 downward, and in turn drives the ejector block 507 welded to the upper end of the second top post 503 downward. When the ejector block 507 contacts the second limit block 504, it is blocked and stops moving downward.

[0034] Specifically, the feeding assembly 6 includes: a sloping plate 601, a first push rod 603, a first lead screw 605, and a second gear 607; the sloping plate 601 is connected to the inner wall of the worktable 1 via a rotating shaft; the first push rod 603 is connected to the lower end of the sloping plate 601 via a rotating shaft; the first lead screw 605 is threaded into the first push rod 603; and the second gear 607 is keyed to the surface of the first lead screw 605.

[0035] Furthermore, the forging slides orderly from the inclined plate 601 into the storage box 3. The forging is buffered when it passes the rubber sheet 602 to prevent damage. The rotation of the second gear 607 drives the first lead screw 605 to rotate, so the first push rod 603 can push the inclined plate 601 to move.

[0036] Specifically, the feeding assembly 6 includes: a first gear 606, a second connecting post 608, a fourth connecting block 604, and a rubber sheet 602; the first gear 606 meshes above the second gear 607; the second connecting post 608 is keyed to the inside of the first gear 606; the fourth connecting block 604 is welded to the other end of the second connecting post 608; and the rubber sheet 602 is pasted on the surface of the inclined plate 601.

[0037] Furthermore, the forging is cushioned when it passes the rubber sheet 602 to prevent damage. When the inclination of the inclined plate 601 needs to be adjusted, the handle is turned, which in turn drives the fourth connecting block 604 to rotate, drives the second connecting column 608 to rotate, and then drives the first gear 606 to rotate. The first gear 606 and the second gear 607 mesh with each other, and the rotation of the second gear 607 drives the first lead screw 605 to rotate.

[0038] Specifically, the feeding assembly 7 includes: a motor 701, a second lead screw 702, and a second push rod 703; the motor 701 is located on the left side of the worktable 1; the second lead screw 702 is keyed to the power output end of the motor 701; and the second push rod 703 is threaded to the surface of the second lead screw 702.

[0039] Furthermore, the motor 701 is started, the second lead screw 702 rotates, driving the second push rod 703 to move horizontally until the forging is pushed onto the inclined plate 601.

[0040] In use, the forging blank is first placed on the ejector block 507, and the hydraulic cylinder 2 is activated, which in turn moves the first connecting column 401 downward, thus moving the first connecting block 402 downward. At this time, the second connecting block 403 moves downward, which in turn moves the pressure block 405 downward. When the second connecting block 403 moves downward, it moves the third connecting block 501 downward, which in turn moves the first ejector column 502 downward. At this time, the return spring 505 deforms, pulling the third limit block 506 downward, thus moving the second ejector column 503 downward, which in turn moves the ejector block 507 welded to the upper end of the second ejector column 503 downward. When the ejector block 507 contacts the second limit block 504, it is blocked and stops moving downward. At this time, the first ejector column 502 continues to move downward until the pressure block 405 contacts the ejector block 507. At this time, the forging blank deforms. After the deformation is completed, the power output end of the hydraulic cylinder 2 is raised, which in turn moves the pressure block 405 away from the forging blank. When the forging is being processed, the third connecting block 501 also rises, which in turn drives the first ejector 502 to rise. When the upper end of the first ejector 502 contacts the ejector block 507, it pushes the forging to rise, which in turn pushes the forging to rise until it is demolded. At this time, the motor 701 is started, the second lead screw 702 rotates, which drives the second push rod 703 to move horizontally until the forging is pushed to the inclined plate 601. The forging slides orderly from the inclined plate 601 into the storage box 3. The forging is buffered when it passes the rubber sheet 602 to prevent damage. When it is necessary to adjust the inclination of the inclined plate 601, the handle is turned, which drives the fourth connecting block 604 to rotate, which drives the second connecting column 608 to rotate, which in turn causes the first gear 606 to rotate. The first gear 606 and the second gear 607 mesh with each other. The rotation of the second gear 607 drives the first lead screw 605 to rotate. Therefore, the first push rod 603 can push the inclined plate 601 to move.

[0041] In summary, this utility model activates the hydraulic cylinder 2, which in turn moves the first connecting column 401 downward, causing the pressure block 405 to press down, the third connecting block 501 downward, and the first top column 502 downward. At this time, the return spring 505 deforms, pulling the third limiting block 506 downward, thus moving the second top column 503 downward, and consequently the ejector block 507 welded to the upper end of the second top column 503 downward. When the ejector block 507 contacts the second limiting block 504, it is blocked and stops moving downward. At this time, the first top column 502 continues to move downward until the pressure block 405 contacts the ejector block 507. At this time, the forging blank deforms, causing the power output end of the hydraulic cylinder 2 to rise, thereby causing the pressure block 405 to detach from the forging. At this time, the third connecting block 501 also rises, thereby causing the first top column 502 to rise. When the upper end of the first top column 502 contacts the ejector block 507, it pushes it upward, thereby pushing the forging upward until it is demolded. This invention, by rotating the handle, drives the fourth connecting block 604 to rotate, which in turn drives the second connecting column 608 to rotate, thereby causing the first gear 606 to rotate. The first gear 606 meshes with the second gear 607, and the rotation of the second gear 607 drives the first lead screw 605 to rotate. Therefore, the first push rod 603 can push the inclined plate 601 to move. Alternatively, by starting the motor 701, the second lead screw 702 rotates, driving the second push rod 703 to move horizontally until the forging is pushed onto the inclined plate 601. The forging then slides orderly from the inclined plate 601 into the storage box 3. The forging is cushioned when passing over the rubber sheet 602 to prevent damage.
