Description

Technical Field

[0001] This utility model belongs to the field of injection mold clamping technology, specifically relating to a novel injection mold clamping component. Background Technology

[0002] Injection molds are process equipment used in plastic molding. They are made by injecting heated and molten plastic raw materials into a closed mold cavity through the screw of an injection molding machine under high pressure. After cooling and solidification, the mold is opened and the finished product is removed. Mold closing is the clamping of two molds together. Mold closing components can guide and position the molds during closing. For example, the precision mold closing mechanism of an injection mold for automotive exterior parts disclosed in the utility model with authorization announcement number CN222628529U uses clamping components to clamp the first mold and the second mold, and uses displacement components to make the movement of the first mold and the second mold more stable.

[0003] The existing technology still has the following problems when used: The device guides the movement of the first and second molds by setting displacement grooves and displacement blocks. However, the displacement grooves can damage the integrity of the base plate and reduce its structural strength. The base plate is also prone to deformation near the displacement groove, which can affect its service life. The device limits the movement of the clamping plate by rotating the threaded rods on both sides of the first and second molds in sequence. However, it is difficult for operators to accurately control the distance the clamping plate moves, which can cause the first and second molds to misalign when they come into contact, reducing the mold closing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a novel injection mold clamping assembly to solve the technical problems mentioned in the background.

[0005] The specific technical solution adopted in this utility model is as follows: A novel injection mold clamping assembly includes: Mounting plate, with two injection mold bodies disposed on the top of the mounting plate; A drive mechanism is located at the bottom of the mounting plate and is used to drive the two injection mold bodies to move closer together to close the mold. A clamping mechanism is symmetrically arranged on the top surface of the mounting plate. The clamping mechanism is used to clamp and fix the injection mold body.

[0006] In a preferred embodiment, support columns are fixedly installed at each of the four corners of the bottom surface of the mounting plate.

[0007] In a preferred embodiment, the driving mechanism includes a U-shaped plate, a bidirectional lead screw, a first guide rod, a servo motor, a first fixed plate, and a second fixed plate. The bottom surface of the mounting plate is slidably connected to a symmetrical U-shaped plate. The bidirectional lead screw and the first guide rod are disposed through the interior of the U-shaped plate. A servo motor is disposed on the side of the bidirectional lead screw. The output end of the servo motor is fixedly connected to the bidirectional lead screw. The bottom surface of the mounting plate is fixedly disposed to a first fixed plate and a second fixed plate. The housing of the servo motor is fixedly connected to the first fixed plate. The output end of the servo motor passes through the first fixed plate and is rotatably connected to the first fixed plate.

[0008] In a preferred embodiment, the bidirectional lead screw is threadedly connected to the U-shaped plate, and the end of the bidirectional lead screw away from the servo motor is rotatably connected to the second fixed plate through a bearing. The left and right sides of the first guide rod are respectively fixedly connected to the first fixed plate and the second fixed plate.

[0009] In a preferred embodiment, the clamping mechanism includes a base plate, a clamping plate, a third fixed plate, a second guide rod, a fourth fixed plate, knobs, threaded rods, a moving block, and connecting rods. Symmetrical base plates are slidably connected to the top surface of the mounting plate, symmetrical clamping plates are slidably connected to the top surface of the base plates, and symmetrical third fixed plates are fixedly mounted on the top surface of the base plates. Second guide rods are fixedly mounted on the opposite sides of the clamping plates, and fourth fixed plates are fixedly mounted on the opposite sides of the base plates. Symmetrical knobs are located above the mounting plate, and threaded rods are fixedly mounted on the opposite sides of the knobs. A moving block is penetrated through the outer side of the threaded rod, and symmetrical connecting rods are hinged to the front and rear sides of the moving block. The other end of the connecting rod is hinged to the second guide rod.

[0010] In a preferred embodiment, the width of the base plate is the same as that of the injection mold body, and both the front and rear sides of the base plate are fixedly connected to the U-shaped plate. The sides of the clamping plates that are close to each other are rough surfaces. The second guide rod passes through the third fixed plate and is slidably connected to the third fixed plate. The bottom surface of the fourth fixed plate is slidably connected to the mounting plate. The threaded rod is threadedly connected to the moving block. The end of the threaded rod away from the knob is rotatably connected to the fourth fixed plate through a bearing.

[0011] The technical effects achieved by this utility model are as follows: This utility model, by setting a drive mechanism, controls a servo motor to drive a bidirectional lead screw to rotate, which can drive two U-shaped plates to move in a direction that brings them closer to each other. The movement of the U-shaped plates causes the base plates to move closer to each other, thereby causing the injection mold bodies on the base plates to move closer to each other for mold closing. The drive mechanism can reduce damage to the integrity of the mounting plate, thereby extending the service life of the mounting plate. This invention utilizes a clamping mechanism to place the injection mold body on the top surface of the base plate and tightly against the fourth fixing plate. Rotating the knob drives the threaded rod to rotate, which in turn moves the moving block away from the fourth fixing plate. The movement of the moving block causes the connecting rod to rotate simultaneously, which in turn moves the second guide rod towards each other. The movement of the second guide rod causes the clamping plates to move closer together. When the clamping plates contact the injection mold body, they can push the injection mold body to slide on the top surface of the base plate until both base plates are in contact with and tightly against the injection mold body. This clamps and fixes the injection mold body in the center of the top surface of the base plate, aligning the two injection mold bodies and improving mold closing efficiency.

[0018] Please see the appendix Figure 1 As shown, this utility model provides a novel injection mold clamping assembly, including: a mounting plate 100, a driving mechanism 300 and a clamping mechanism 400. Support columns 101 are fixedly provided at the four corners of the bottom surface of the mounting plate 100. Two injection mold bodies 200 are provided on the top of the mounting plate 100. The injection mold bodies 200 are close to each other and snapped together to facilitate injection molding.

[0019] In a preferred embodiment, please refer to Figures 1 to 3 A drive mechanism 300 is provided at the bottom of the mounting plate 100. The drive mechanism 300 consists of a U-shaped plate 301, a bidirectional lead screw 302, a first guide rod 303, a servo motor 304, a first fixing plate 305, and a second fixing plate 306. A symmetrical U-shaped plate 301 is slidably connected to the bottom surface of the mounting plate 100. A bidirectional lead screw 302 and a first guide rod 303 are provided through the U-shaped plate 301. Both the bidirectional lead screw 302 and the first guide rod 303 are located below the mounting plate 100. A servo motor 304 is provided on the side of the bidirectional lead screw 302. The output end of the servo motor 304 is fixedly connected to the bidirectional lead screw 302. A first fixing plate 305 and a second fixing plate 306 are fixedly provided on the bottom surface of the mounting plate 100. The housing of the servo motor 304 is fixedly connected to the first fixing plate 305. The output end of the servo motor 304 passes through the first fixing plate 305 and is rotatably connected to the first fixing plate 305.

[0020] In this embodiment, the bidirectional lead screw 302 is threadedly connected to the U-shaped plate 301, and the end of the bidirectional lead screw 302 away from the servo motor 304 is rotatably connected to the second fixed plate 306 through a bearing. The left and right sides of the first guide rod 303 are fixedly connected to the first fixed plate 305 and the second fixed plate 306 respectively.

[0021] In this embodiment, controlling the servo motor 304 to drive the bidirectional lead screw 302 to rotate can drive the two U-shaped plates 301 to move in a direction that brings them closer to each other. The first guide rod 303 guides the movement of the U-shaped plates 301. The movement of the U-shaped plates 301 can drive the top injection mold body 200 to move closer to each other for mold closing. The drive mechanism 300 can reduce damage to the integrity of the mounting plate 100, thereby extending the service life of the mounting plate 100.

[0022] In a preferred embodiment, please refer to Figures 1 to 4 The top surface of the mounting plate 100 is provided with symmetrical clamping mechanisms 400. Each clamping mechanism 400 consists of a base plate 401, a clamping plate 402, a third fixing plate 403, a second guide rod 404, a fourth fixing plate 405, a knob 406, a threaded rod 407, a moving block 408, and a connecting rod 409. The top surface of the mounting plate 100 is slidably connected to the symmetrical base plate 401, the top surface of the base plate 401 is slidably connected to the symmetrical clamping plate 402, and the top surface of the base plate 401 is fixedly provided with the symmetrical third fixing plate 405. 3. A second guide rod 404 is fixedly installed on the side of the clamping plate 402 that is far apart from each other. A fourth fixing plate 405 is fixedly installed on the side of the base plate 401 that is far apart from each other. A symmetrical knob 406 is provided above the mounting plate 100. A threaded rod 407 is fixedly installed on the side of the knob 406 that is close to each other. A moving block 408 is provided through the outside of the threaded rod 407. A symmetrical connecting rod 409 is hinged on the front and rear sides of the moving block 408. The other end of the connecting rod 409 is hinged to the second guide rod 404.

[0023] In this embodiment, the width of the base plate 401 is the same as that of the injection mold body 200. The front and rear sides of the base plate 401 are fixedly connected to the U-shaped plate 301. The sides of the clamping plates 402 that are close to each other are rough surfaces. The second guide rod 404 passes through the third fixed plate 403 and is slidably connected to the third fixed plate 403. The second guide rod 404 cooperates with the third fixed plate 403 to guide the movement of the clamping plate 402. The bottom surface of the fourth fixed plate 405 is slidably connected to the mounting plate 100. The threaded rod 407 is threadedly connected to the moving block 408. The end of the threaded rod 407 away from the knob 406 is rotatably connected to the fourth fixed plate 405 through a bearing.

[0024] In this embodiment, the injection mold body 200 is placed on the top surface of the base plate 401 and closely attached to the fourth fixing plate 405. Rotating the knob 406 drives the threaded rod 407 to rotate. The rotation of the threaded rod 407 drives the moving block 408 to move away from the fourth fixing plate 405. The movement of the moving block 408 drives the connecting rod 409 to rotate simultaneously. The rotation of the connecting rod 409 drives the second guide rod 404 to move in a direction that brings them closer together. The movement of the second guide rod 404 can drive the clamping plates 402 to move closer together. When the clamping plates 402 contact the injection mold body 200, they can push the injection mold body 200 to slide on the top surface of the base plate 401 until both base plates 401 are in contact with and closely attached to the injection mold body 200, thereby clamping the injection mold body 200 and fixing it to the center of the top surface of the base plate 401, so that the two injection mold bodies 200 are aligned with each other, improving the mold closing efficiency.

[0025] The working principle of this utility model is as follows: When using the device, rotating the knob 406 causes the threaded rod 407 to rotate. The rotation of the threaded rod 407 causes the moving block 408 to move closer to the fourth fixed plate 405. The movement of the moving block 408 causes the connecting rod 409 to rotate simultaneously. The rotation of the connecting rod 409 causes the second guide rod 404 to move away from each other. The movement of the second guide rod 404 causes the clamping plates 402 to move away from each other until the distance between the two clamping plates 402 reaches its maximum. The injection mold body 200 is then placed on the top surface of the base plate 401 and pressed tightly against the fourth fixed plate 405. Rotating the knob 406 in the opposite direction causes the clamping plates 402 to move closer together. When the clamping plates 402 contact the injection mold body 200, they can push the injection mold body... The body 200 slides on the top surface of the base plate 401 until both base plates 401 are in contact with and tightly adhere to the injection mold body 200, thereby clamping the injection mold body 200 and fixing it to the center of the top surface of the base plate 401, aligning the two injection mold bodies 200 with each other. Controlling the servo motor 304 to drive the bidirectional lead screw 302 to rotate can drive the two U-shaped plates 301 to move in a direction that brings them closer to each other. The movement of the U-shaped plates 301 causes the base plates 401 to move closer to each other, thereby causing the injection mold bodies 200 on the base plate 401 to move closer to each other for mold closing. The drive mechanism 300 can reduce damage to the integrity of the mounting plate 100, thereby extending the service life of the mounting plate 100.

[0026] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
