Description

Technical Field

[0001] This utility model relates to the field of extrusion die technology, and in particular to an extrusion die with a quick die-changing structure. Background Technology

[0002] Quick-change extrusion dies are a type of die design used to improve production efficiency. They are widely used in the extrusion processing of materials such as plastics and metals. The background technology mainly solves the problems of long die change times and low efficiency in traditional dies. By simplifying the die change process, optimizing the die clamping device and the quick adjustment mechanism, the production line can quickly switch between different dies, reduce downtime, improve production efficiency, and reduce labor intensity.

[0003] However, in actual use, the following shortcomings still exist. For example, the existing extrusion dies cannot be changed quickly. The inability to change dies quickly means that a long downtime is required when changing to different products or dies. This directly leads to an increase in production line downtime, thereby reducing overall production efficiency. Long downtime not only means a reduction in production time, but may also increase indirect costs such as energy consumption, labor costs, and equipment depreciation. In addition, in order to cope with the problem of long die changeover time, companies may need to maintain a higher inventory level, which further increases inventory costs.

[0004] Therefore, this utility model proposes a quick-change extrusion die to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and propose a quick-change extrusion die.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a quick-change extrusion die, comprising:

[0007] The base plate and the support seat mounted on the base plate, with an extrusion die mounted on the support seat;

[0008] A lifting assembly is placed on the base plate near the bottom of the support seat. The lifting assembly includes a first electric push rod installed on the base plate near the bottom of the support seat. The output end of the first electric push rod is fixedly connected to a support plate. A moving rod is fixedly connected on the base plate near the first gear. A hollow tube is slidably connected inside the moving rod.

[0009] A fixing assembly is located on one side of the bottom of a support plate. The fixing assembly includes a second electric push rod installed on one side of the bottom of the support plate. A moving block is fixedly connected to the output end of the second electric push rod. A first rotating rod is rotatably connected to the moving block. A connecting rod is rotatably connected to the end of the first rotating rod away from the moving block. A rack is fixedly connected to the side of the connecting rod near the top. A second gear meshes on the rack. A second rotating rod is fixedly connected to the top of the second gear. A first limiting block is fixedly connected to the top of the second rotating rod. A second limiting block is fixedly connected to the side of the extrusion die near the first limiting block. A limiting groove is formed on the second limiting block.

[0010] In a preferred embodiment, a support block is fixedly connected to the side of the base plate near the first electric push rod, and a rotating shaft is rotatably connected to the support block.

[0011] The beneficial effects of adopting the above-mentioned further solution are: since a support block is fixedly connected to the side of the base plate near the first electric push rod, the base plate can support and fix the support block; since a rotating shaft is rotatably connected to the support block, the support block can support and limit the rotating shaft when it rotates.

[0012] In a preferred embodiment, a first gear is fixedly connected to the rotating shaft, and a toothed groove is provided on the side of the moving rod near the first gear, with the first gear meshing with the toothed groove.

[0013] The beneficial effects of adopting the above-mentioned further solution are as follows: Since the first gear is fixedly connected on the rotating shaft, the rotating shaft can support and fix the first gear. Since the moving rod has a toothed groove on the side near the first gear, and the first gear meshes with the toothed groove, when the hollow tube moves, the first gear can drive the first gear to rotate through the cooperation between the first gear and the toothed groove, thereby controlling the two hollow tubes to rise or fall synchronously.

[0014] In a preferred embodiment, a groove is provided on the side of the support plate near the connecting rod, and the connecting rod is slidably connected in the groove.

[0015] The beneficial effect of adopting the above-mentioned further solution is that, since a groove is provided on the side of the support block near the connecting rod, and the connecting rod is slidably connected in the groove, the groove can limit the movement of the connecting rod when it moves in the groove, preventing the connecting rod from deviating during movement.

[0016] In a preferred embodiment, the second gear is rotatably connected to the support plate.

[0017] The beneficial effect of adopting the above-mentioned further solution is that, since the second gear is rotatably connected to the support plate, the support plate can provide support and limit the connecting rod when the second gear rotates on the support plate.

[0018] In a preferred embodiment, the second rotating rod is disposed in the limiting groove, and the first limiting block is disposed on top of the second limiting block.

[0019] The beneficial effect of adopting the above-mentioned further solution is that, since the second rotating rod is set in the limiting groove and the first limiting block is set on the top of the second limiting block, the first limiting block can play a limiting role on the second limiting block, so that the extrusion mold can be fixed on the support base.

[0020] In a preferred embodiment, a limit rod is fixedly connected to the top of the support base near the side of the extrusion die.

[0021] The beneficial effect of adopting the above-mentioned further solution is that, since the top of the support base is fixedly connected to the side near the extrusion die, the extrusion die can be positioned during extrusion by means of the set limit rod, so as to prevent the die from shifting during extrusion.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] In this invention, when the height of the support plate needs to be adjusted, the position of the support plate can be changed by controlling the first electric push rod, thereby driving the fixing component to rise or fall. Then, the fixing component drives the moving block to slide along the moving rod via the second electric push rod, causing the first rotating rod to rotate around the moving block. This allows the connecting rod to drive the connecting rod and the rack to move. Simultaneously, the rack meshes with the second gear, causing the second gear to rotate. When the second gear rotates, it drives the second rotating rod to rotate as well, causing the first limiting block to rotate. The limiting groove on the second limiting block will cooperate with the first limiting block to ensure that the extrusion die remains stable during operation, achieving rapid die change and improving production efficiency and product quality.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0034] like Figures 1-4 As shown, this embodiment provides a technical solution: a quick-change extrusion die, comprising:

[0035] The base plate 1 and the support seat 2 provided on the base plate 1, and the extrusion die 3 is provided on the support seat 2;

[0036] Lifting assembly 4 is placed on the base plate 1 on one side near the bottom of the support seat 2. The lifting assembly 4 includes a first electric push rod 41 installed on the base plate 1 on one side near the bottom of the support seat 2. The output end of the first electric push rod 41 is fixedly connected to a support plate 42. A moving rod 46 is fixedly connected on the base plate 1 on one side near the first gear 45. A hollow tube 47 is slidably connected inside the moving rod 46.

[0037] The fixing component 5 is located on one side of the bottom of the support plate 42. The fixing component 5 includes a second electric push rod 51 installed on one side of the bottom of the support plate 42. A moving block 52 is fixedly connected to the output end of the second electric push rod 51. A first rotating rod 53 is rotatably connected to the moving block 52. A connecting rod 54 is rotatably connected to the end of the first rotating rod 53 away from the moving block 52. A rack 55 is fixedly connected to the side of the connecting rod 54 near the top. A second gear 56 meshes with the rack 55. A second rotating rod 57 is fixedly connected to the top of the second gear 56. A first limiting block 58 is fixedly connected to the top of the second rotating rod 57. A second limiting block 510 is fixedly connected to the side of the extrusion die 3 near the first limiting block 58. A limiting groove 511 is formed on the second limiting block 510. First, the base plate 1 serves as the basic support structure for the entire equipment. A support seat 2 is provided on the base plate 1 for placing the extrusion die 3. Second, the lifting component 4... The first electric push rod 41 controls the up-and-down movement of the support plate 42. When the height of the support plate 42 is required, the position of the support plate 42 can be changed by controlling the first electric push rod 41, thereby driving the fixed component 5 to rise or fall. Then, the fixed component 5 drives the moving block 52 to slide along the moving rod 46 through the second electric push rod 51, thereby causing the first rotating rod 53 to rotate around the moving block 52, so that the connecting rod 54 can drive the connecting rod 54 and the rack 55 to move. At the same time, the rack 55 meshes with the second gear 56, causing the second gear 56 to rotate. When the second gear 56 rotates, it will drive the second rotating rod 57 to rotate together, causing the first limiting block 58 to rotate as well. The limiting groove 511 on the second limiting block 510 will cooperate with the first limiting block 58 to ensure that the extrusion mold 3 remains stable during operation, realizing rapid mold changing of the extrusion mold 3, improving production efficiency and product quality.

[0038] The above solutions also have the problem that the support plate 42 cannot provide stability when it is rising or falling. Figures 1-3As shown: A support block 43 is fixedly connected to the side of the base plate 1 near the first electric push rod 41. A rotating shaft 44 is rotatably connected to the support block 43. Because the support block 43 is fixedly connected to the side of the base plate 1 near the first electric push rod 41, the base plate 1 can support and fix the support block 43. Because the rotating shaft 44 is rotatably connected to the support block 43, the support block 43 can support and limit the rotation of the rotating shaft 44. A first gear 45 is fixedly connected to the rotating shaft 44. A moving rod 46 is located near the first gear 45. A toothed groove 48 is provided on one side of the hollow tube 47, and the first gear 45 meshes with the toothed groove 48. Since the first gear 45 is fixedly connected to the rotating shaft 44, the rotating shaft 44 can support and fix the first gear 45. Since the toothed groove 48 is provided on the side of the moving rod 46 near the first gear 45, and the first gear 45 meshes with the toothed groove 48, when the hollow tube 47 moves, the first gear 45 can drive the first gear 45 to rotate through the cooperation of the first gear 45 and the toothed groove 48, thereby controlling the two hollow tubes 47 to rise or fall synchronously.

[0039] like Figures 1-2 as well as Figure 4 As shown, a groove 59 is provided on the side of the support plate 42 near the connecting rod 54. The connecting rod 54 is slidably connected in the groove 59. Since the groove 59 is provided on the side of the support block 43 near the connecting rod 54, and the connecting rod 54 is slidably connected in the groove 59, the groove 59 can limit the movement of the connecting rod 54 when it moves in the groove 59, preventing the connecting rod 54 from deviating during movement. The second gear 56 is rotatably connected to the support plate 42. On 42, when the second gear 56 rotates on the support plate 42, the support plate 42 can support and limit the connecting rod 54. The second rotating rod 57 is set in the limiting groove 511, and the first limiting block 58 is set on the top of the second limiting block 510. Since the second rotating rod 57 is set in the limiting groove 511 and the first limiting block 58 is set on the top of the second limiting block 510, the first limiting block 58 can limit the second limiting block 510, so that the extrusion mold 3 can be fixed on the support base 2.

[0040] like Figure 1 As shown, a limiting rod 6 is fixedly connected to the top of the support base 2 near the side of the extrusion mold 3. Because the limiting rod 6 is fixedly connected to the top of the support base 2 near the side of the extrusion mold 3, the extrusion mold 3 can be positioned during extrusion by means of the limiting rod 6, so as to prevent the mold from shifting during extrusion.

[0041] Working principle:

[0042] like Figures 1-4As shown, firstly, the base plate 1 serves as the basic support structure for the entire equipment. A support base 2 is installed on the base plate 1 to hold the extrusion mold 3. Secondly, the lifting assembly 4 controls the up-and-down movement of the support plate 42 via a first electric push rod 41. When the required height of the support plate 42 is needed, the position of the support plate 42 can be changed by controlling the first electric push rod 41, thereby causing the fixing assembly 5 to rise or fall. Thirdly, the fixing assembly 5 drives the moving block 52 to slide along the moving rod 46 via a second electric push rod 51, thereby causing the first rotating rod 53 to rotate around... The rotating block 52 causes the connecting rod 54 to move along with the rack 55. Simultaneously, the rack 55 meshes with the second gear 56, causing the second gear 56 to rotate. When the second gear 56 rotates, it drives the second rotating rod 57 to rotate as well, causing the first limiting block 58 to rotate as well. The limiting groove 511 on the second limiting block 510 will cooperate with the first limiting block 58 to ensure that the extrusion die 3 remains stable during operation. This enables rapid die changing of the extrusion die 3, improving production efficiency and product quality.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
