Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to an injection mold for a double-layer air guide plate. Background Technology

[0002] Injection molds are the core tools in the production of plastic products and an important process equipment for producing various industrial products. They form products of specific shapes and sizes by heating plastic materials and injecting them into the mold. With the rapid development of the plastics industry and the widespread application of plastic products in industries such as aviation, aerospace, electronics, machinery, shipbuilding and automobiles, the application scope of injection molds is becoming increasingly broad.

[0003] When using existing double-layer air guide plate injection molds, a certain amount of air is contained inside the mold and is not expelled. This air mixes with the injected molten material to form bubbles. At the same time, some bubbles are also not eliminated in the injected molten material. These bubbles affect the appearance and performance of the product, leading to a decrease in the factory's product qualification rate. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the prior art. When using the existing double-layer air guide plate injection mold, a certain amount of air is contained in the mold and is not discharged outside the mold. This part of the air will mix with the injected molten raw material to form bubbles. At the same time, some bubbles in the molten raw material are not eliminated. The bubbles will affect the appearance and performance of the product, resulting in a decrease in the product qualification rate of the factory. Therefore, a double-layer air guide plate injection mold is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A double-layer air guide plate injection mold includes an upper mold and a lower mold, wherein the outer surface of the upper mold is provided with a feed port, and the upper mold and the lower mold are connected.

[0007] An air-bubble elimination component is installed on the upper mold. The air-bubble elimination component includes a square plate, a push plate, a pressure rod, a cylinder, a moving plate, and an impact rod. The square plate is fixedly connected to the outer surface of the upper mold. Multiple cylinders are installed in a linear array on the outer surface of the square plate. The moving plate is slidably connected inside the cylinder. The impact rod is fixedly connected to the outer surface of the moving plate. A return spring is fixedly connected between the moving plate and the inner wall of the cylinder. The push plate is slidably connected between the two ends of the square plate. One end of the moving plate passes through the cylinder and is fixedly connected to the push plate. The pressure rod is fixedly connected to one end of the push plate.

[0008] Preferably, the upper mold is fixedly connected to an air extraction box, and the air extraction box and the upper mold are fixedly connected through an air extraction pipe, and one end of the impact rod is spherical.

[0009] Preferably, a fixing plate is fixedly connected to the upper surface of the upper mold, a rotating shaft is rotatably connected between the fixing plate and the inner wall of the suction box, and a piston plate is slidably connected inside the suction box.

[0010] Preferably, the piston plate is threadedly connected to the rotating shaft, a straight plate is fixedly connected to the outer surface of the piston plate, and multiple extrusion plates are installed in a linear array on the outer surface of the straight plate. The straight plate is slidably connected to the inner wall of the suction box, and the extrusion plates are slidably connected to the pressure rod.

[0011] Preferably, the upper mold is fixedly connected to two ends of a fixing block, the lower mold is fixedly connected to two ends of a square cavity, a trapezoidal rod is fixedly connected to the outer surface of the fixing block, and the trapezoidal rod is slidably connected to the square cavity.

[0012] Preferably, a locking plate is slidably connected inside the square cavity, the trapezoidal rod is slidably connected to the locking plate, a pull plate is fixedly connected to one end of the locking plate, and a straight spring is provided between the pull plate and the outer surface of the square cavity.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Through the combined action of parts such as the push plate, cylinder, moving plate, and return spring, the impact rod strikes the outer surface of the upper mold, causing the upper mold to vibrate. This vibration is transmitted to the molten material, breaking up any air bubbles that have formed within the molten material, thus eliminating the air bubbles and further improving the quality and performance of the product.

[0015] 2. Through the combined action of parts such as piston plate, rotating shaft, air extraction pipe, and air extraction box, the air between the upper and lower molds is drawn into the air extraction box, ensuring a near-vacuum state between the upper and lower molds. This prevents the air between the upper and lower molds from coming into contact with the molten material, which would cause the molten material to generate many bubbles, thus preventing the formation of bubbles in the material from affecting product quality.

[0016] 3. The trapezoidal rod, locking plate, square cavity, pull plate and other accessories work together to lock the trapezoidal rod in place, achieving a quick fixation effect without manual intervention, saving manpower and improving work efficiency. When it is necessary to release the lock, simply pull the pull plate outward, which facilitates the disassembly of the upper and lower molds. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0024] Reference Figures 1-4 A double-layer air guide plate injection mold includes an upper mold 1 and a lower mold 2. The outer surface of the upper mold 1 is provided with a feed port, and the upper mold 1 and the lower mold 2 are connected.

[0025] An air-bubble elimination component is installed on the upper mold 1. The air-bubble elimination component includes a square plate 10, a push plate 11, a pressure rod 12, a cylinder 13, a moving plate 14, and an impact rod 15. The square plate 10 is fixedly connected to the outer surface of the upper mold 1 and is U-shaped. Multiple cylinders 13 are arranged in a linear array on the outer surface of the square plate 10. The moving plate 14 is slidably connected inside the cylinder 13 and is divided into two parts. The part inside the cylinder 13 is circular, and the other part is similar to a T-shape. The impact rod 15 is fixedly connected to the outer surface of the moving plate 14. A return spring 16 is fixedly connected between the moving plate 14 and the inner wall of the cylinder 13. The return spring 16 has a large elastic force. The push plate 11 is slidably connected between the two ends of the square plate 10. One end of the moving plate 14 passes through the cylinder 13 and is fixedly connected to the push plate 11. The pressure rod 12 is fixedly connected to one end of the push plate 11. The end of the pressure rod 12 away from the push plate 11 is spherical, which is convenient for being squeezed and pushed.

[0026] An upper mold 1 is fixedly connected to a vacuum box 3, which is connected to the upper mold 1 via a vacuum pipe 4. One end of the impact rod 15 is spherical. A fixing plate 6 is fixedly connected to the upper surface of the upper mold 1. A rotating shaft 5 is rotatably connected between the fixing plate 6 and the inner wall of the vacuum box 3. A piston plate 7 is slidably connected inside the vacuum box 3. The piston plate 7 and the vacuum box 3 are leak-proof. The piston plate 7 is threadedly connected to the rotating shaft 5, and the piston plate 7 and the rotating shaft 5 are sealed. A straight plate 8 is fixedly connected to the outer surface of the piston plate 7. Multiple extrusion plates 9 are installed in a linear array on the outer surface of the straight plate 8. The straight plate 8 is slidably connected to the inner wall of the vacuum box 3. The pressure rod 12 is slidably connected. The upper mold 1 is fixedly connected to both ends of a fixed block 17. The lower mold 2 is fixedly connected to both ends of a square cavity 19. A trapezoidal rod 18 is fixedly connected to the outer surface of the fixed block 17. The lower end of the trapezoidal rod 18 is set in a right-angled trapezoid and is called a trapezoidal block. The inclined surface of the trapezoidal block will contact the locking plate 20. When it moves downward, it will push the locking plate 20 to move outward. The trapezoidal rod 18 is slidably connected to the square cavity 19. The locking plate 20 is slidably connected inside the square cavity 19. The trapezoidal rod 18 is slidably connected to the locking plate 20. A pull plate 21 is fixedly connected to one end of the locking plate 20. A straight spring is provided between the pull plate 21 and the outer surface of the square cavity 19.

[0027] In this invention, the feed port on the upper mold 1 is first connected to an external feed pipe. Then, by rotating the shaft 5, the piston plate 7 moves within the vacuum chamber 3. As the piston plate 7 moves within the vacuum chamber 3, the vacuum chamber 3 draws air from between the upper mold 1 and the lower mold 2 through the vacuum pipe 4, ensuring a near-vacuum state between the upper mold 1 and the lower mold 2. This prevents the air between the upper mold 1 and the lower mold 2 from contacting the molten material, which could cause numerous air bubbles to form and affect product quality. After the vacuuming process is complete, the molten material is poured into the space between the upper mold 1 and the lower mold 2 through the feed port. After the feeding process is complete, the shaft 5 is rotated again, causing the piston plate 7 and the straight plate 8 to move. The straight plate 8 gradually approaches the pressure rod 12 until the push plate 11 on the straight plate 8 contacts the pressure rod 12. When the pressure rod 12 contacts the shaft 5, the push plate 11 pushes the pressure rod 12 to move. The movement of the pressure rod 12 drives the push plate 11 to move, which in turn drives the moving plate 14 to move. The moving plate 14 presses the return spring 16 inward. At the same time, the moving plate 14 drives the impact rod 15 to move away from the upper mold 1. When the pressure rod 12 passes through the extrusion plate 9, it is now between the two extrusion plates 9 and is no longer subjected to the extrusion action of the extrusion plates 9. The moving plate 14 performs a reset under the action of the return spring 16. The moving plate 14 drives the impact rod 15 to move, and the impact rod 15 impacts the upper mold 1. The upper mold 1 vibrates, and this vibration is transmitted to the molten material, breaking the bubbles that have already formed in the molten material. This completes the work of eliminating bubbles in the molten material, thereby improving the quality and performance of the product.

[0028] When the upper mold 1 and the lower mold 2 are fixed, simply place the upper mold 1 on the lower mold 2. The trapezoidal rod 18 on the upper mold 1 will enter the square cavity 19. Under the weight of the upper mold 1 itself, the trapezoidal rod 18 will press the locking plate 20 outward. When the trapezoidal block at one end of the trapezoidal rod 18 passes through the locking plate 20, the locking plate 20 is no longer subjected to the pressing action of the trapezoidal rod 18. Under the cooperation of the pull plate 21 and the straight spring, the locking plate 20 will be stuck on the upper surface of the trapezoidal block of the trapezoidal rod 18, fixing and locking the trapezoidal rod 18, achieving the effect of quick fixing without manual intervention, saving manpower and improving work efficiency. When it is necessary to release the lock, simply pull the pull plate 21 outward, which facilitates the disassembly of the upper mold 1 and the lower mold 2.
