Description

Technical Field

[0001] This utility model belongs to the technical field of demolding mechanisms, specifically relating to a demolding mechanism for forging blanks. Background Technology

[0002] Forgings refer to workpieces or blanks obtained by forging and deforming metal billets. Forgings can be classified into cold forging, warm forging, and hot forging based on the temperature at which the billet is processed. Cold forging is generally performed at room temperature, while hot forging is performed at a temperature higher than the recrystallization temperature of the metal billet. In practical applications, forged workpieces are prone to getting stuck in the mold, requiring a demolding mechanism for removal. However, existing demolding mechanisms often require cumbersome operations, hindering rapid demolding and resulting in limited practical effectiveness.

[0003] A patent with publication number CN222036683U discloses a mold tooling for forging parts, which includes a hydraulic rod, an upper mold, a lower mold, a pedal, a connecting plate, a storage spring, a rotating rod, a slider, and a lifting plate. When demolding is required, the hydraulic rod first raises the upper mold, separating it from the lower mold. Then, pressing the pedal downwards lowers the connecting plate and compresses the storage spring, causing the rotating rod to rotate and push the slider upwards at an angle, thereby pushing the lifting plate upwards and pushing the workpiece out of the lower mold.

[0004] However, the above solution requires not only controlling the upper mold to rise via hydraulic rods to separate the upper and lower molds during demolding, but also stepping on a pedal after the upper and lower molds have separated to raise the lifting plate for demolding. This increases the complexity of the entire operation, making it difficult to demold the workpiece quickly, and its practical effect is generally limited. Utility Model Content

[0005] To address the problems existing in the background art, this utility model provides a demolding mechanism for forging blanks.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A demolding mechanism for forging blanks includes a worktable. A support frame and a fixed seat are fixedly mounted on the top of the worktable. A pressure plate is fixedly connected to the support frame via a lifting assembly. Two rotating plates are rotatably mounted on the fixed seat, and the two rotating plates are symmetrically arranged. A support plate is slidably mounted in the fixed seat along the vertical direction. An elastic reset member is provided between the support plate and the worktable. The support plate is placed on the two rotating plates and abuts against them. In addition, the pressure plate is located directly above the support plate and is driven by the two rotating plates via a transmission member.

[0008] Furthermore, the lifting assembly includes a hydraulic cylinder, which is fixedly mounted on the support frame, and the telescopic shaft of the hydraulic cylinder is fixedly connected to the pressure plate.

[0009] Furthermore, the elastic reset component includes a slide plate, which is slidably installed through the upper limit of the worktable. The top of the slide plate slidably passes through the fixed seat and is fixedly connected to the bottom of the support plate. A limiting plate is integrally installed at the bottom of the slide plate, and a spring is sleeved on the surface of the slide plate. One end of the spring is fixedly connected to the bottom of the worktable, and the other end is fixedly connected to the top of the limiting plate.

[0010] Furthermore, both the workbench and the fixed base are provided with limiting grooves for the sliding plate to slide through.

[0011] Furthermore, the transmission component includes a connecting plate, which is slidably installed through the upper limit of the worktable and is fixedly connected to the pressure plate; two second sliding grooves are opened on the connecting plate and are symmetrically arranged; a fixing post is fixedly installed on each of the flip plates, and the fixing post corresponds one-to-one with the second sliding groove, and each fixing post is slidably installed in the corresponding second sliding groove.

[0012] Furthermore, a first sliding groove is provided on the support frame, and a sliding rod is fixedly installed in the first sliding groove. The connecting plate is both limited and slidably engaged with the first sliding groove, and is also slidably sleeved on the outer surface of the sliding rod.

[0013] This application has the following beneficial effects:

[0014] During the process of lifting the pressure plate by the lifting assembly, the two flipping plates will automatically flip outward with the cooperation of the transmission components. This not only facilitates the separation of the workpiece from the flipping plates on both sides, but also lifts the support plate, thereby realizing the rapid demolding of the workpiece. The operation is simple and has better practical effect. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: a demolding mechanism for forging blanks includes a worktable 1, a support frame 5 and a fixed seat 2 fixedly installed on the worktable 1, the support frame 5 is fixedly connected to a pressure plate 4 through a lifting assembly; the fixed seat 2 is U-shaped, and an L-shaped flip plate 3 is rotatably installed on each of the two open sides of the fixed seat 2, the two flip plates 3 are arranged facing each other, and the fixed seat 2 and the two flip plates 3 enclose a lidless rectangular box.

[0024] Furthermore, a support block (not marked in the figure) is integrated on the fixed base 2, and the flip plate 3 is located above the support block. The support block can not only provide support, but also ensure the normal flipping of the flip plate 3.

[0025] The lifting assembly includes a hydraulic cylinder 6, which is fixedly installed on the support frame 5. The telescopic shaft of the hydraulic cylinder 6 is fixedly connected to the pressure plate 4, which is located directly above the fixed base 2.

[0026] A support plate 13 is slidably positioned in the vertical direction inside the fixed base 2. The support plate 13 is placed on the two flip plates 3 and abuts against the two flip plates 3. The support plate 13 is opposite to the pressure plate 4 and is also adapted to the coverless rectangular box.

[0027] In addition, an elastic reset component is provided between the support plate 13 and the worktable 1, and the pressure plate 4 is driven by the transmission component to cooperate with the two flip plates 3.

[0028] The elastic reset component includes a slide plate 12, which is slidably installed through the upper limit of the worktable 1. The top of the slide plate 12 slides through the fixed seat 2 and is fixedly connected to the bottom of the support plate 13. A limiting plate is integrally installed at the bottom of the slide plate 12. A spring 11 is sleeved on the surface of the slide plate 12. One end of the spring 11 is fixedly connected to the bottom of the worktable 1, and the other end is fixedly connected to the top of the limiting plate.

[0029] Furthermore, both the workbench 1 and the fixed base 2 are provided with limiting grooves for the sliding plate 12 to slide through.

[0030] The transmission component includes a connecting plate 8, which is slidably installed through the upper limit of the worktable 1. The connecting plate 8 is fixedly connected to the pressure plate 4. Two second sliding grooves 9 are opened on the connecting plate 8, which are symmetrically arranged. The second sliding grooves 9 are composed of a horizontal groove and a vertical groove connected together, specifically in an L-shape. A fixing post 14 is fixedly installed on each flip plate 3, and the fixing post 14 corresponds one-to-one with the second sliding groove 9. Each fixing post 14 is slidably installed in the corresponding second sliding groove 9.

[0031] Furthermore, a first sliding groove 7 is provided on the support frame 5, and a sliding rod 10 is fixedly installed in the first sliding groove 7. The connecting plate 8 is both limited and slidably engaged with the first sliding groove 7, and slidably sleeved on the outer surface of the sliding rod 10.

[0032] Working principle: In actual use, when it is necessary to forge the workpiece, the raw material is placed on the support plate 13, the hydraulic cylinder 6 is started, and the pressure plate 4 is pushed down through the telescopic shaft of the hydraulic cylinder 6. The raw material is forged into a forging through the cooperation of the pressure plate 4, the fixed seat 2 and the flipping plate 3.

[0033] When it is necessary to demold the forged part, the telescopic shaft of the hydraulic cylinder 6 is retracted, causing the pressure plate 4 to drive the connecting plate 8 to rise. At this time, the fixed column 14 slides in the vertical groove of the second slide 9, and the flipping plate 3 does not flip.

[0034] When the fixed column 14 slides to the junction of the vertical and horizontal grooves of the second slide groove 9, as the telescopic shaft of the hydraulic cylinder 6 continuously retracts, the two flipping plates 3 will flip outwards due to the sliding engagement between the fixed column 14 and the second slide groove 9, causing the sides of the workpiece to detach from the flipping plates 3. Simultaneously, the flipping plates 3 will also lift the support plate 13 and compress the spring 11, thereby using the support plate 13 to lift the demolded workpiece, completing the demolding process. During this process, the pressure plate 4 slides relative to both the first slide groove 7 and the slide rod 10.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
