Description

Technical Field

[0001] This utility model relates to the field of injection molding equipment technology, specifically an injection molding device for quantitative material output. Background Technology

[0002] When producing injection molded parts, it is often necessary to use injection molding equipment to inject molten plastic material into a mold for shaping.

[0003] In order to control the injection volume of some existing plastic injection equipment, users need to manually measure the amount of material dispensed, which can easily lead to errors, resulting in too much or too little material dispensed, making the injection equipment inconvenient to use. Therefore, a quantitative dispensing injection equipment is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The present utility model provides a quantitative dispensing injection device, including a storage tank. A first motor is fixedly connected to the outside of the storage tank, and a baffle is fixedly connected to the output end of the first motor. A through groove is formed on the surface of the baffle. A quantitative tube is connected to the inside of the storage tank, and a placement box is connected to the outside of the quantitative tube. An injection molding assembly is connected to the outside of the placement box, and a hydraulic cylinder is fixedly connected to the outside of the placement box. A sealing plate is fixedly connected to the output end of the hydraulic cylinder, and the sealing plate works in conjunction with the quantitative tube. This step, by setting up the baffle, quantitative tube, hydraulic cylinder, and sealing plate, facilitates the dispensing of material because the internal space volume of the quantitative tube is fixed. The plastic material entering from the inside is metered. First, a hydraulic cylinder drives a sealing plate to press against the lower side of the metering tube. Then, plastic material is injected into the storage tank, filling one metering tube along the channel. Next, the baffle is rotated to move the channel away from the metering tube, and the sealing plate is lowered, allowing the metered plastic material to enter the placement box. From there, it flows into the injection molding assembly and is discharged through the assembly. When a larger dose of plastic material needs to be injected, the channel can be moved to connect multiple metering tubes to fill them, thus expanding the metering range of the device. This eliminates the need for manual metering of the plastic material, improving the accuracy of the metering.

[0006] Preferably, a second motor is fixedly connected to the outside of the storage tank, and a gear is fixedly connected to the output end of the second motor. A gear ring meshes with the outside of the gear, and the gear ring is rotatably connected to the storage tank. A stirring rod is fixedly connected to the outside of the gear ring. This step, by setting up the second motor, gear, gear ring, and stirring rod, allows the second motor to drive the gear to rotate after the plastic material is injected into the storage tank. The gear then drives the gear ring to rotate, which in turn drives the stirring rod to rotate. The stirring rod further agitates and mixes the plastic material inside the storage tank, thereby removing air bubbles and making the mixing more uniform, thus improving the stability of the device.

[0007] Preferably, a limiting ring is fixedly connected to the outside of the stirring rod, and a limiting frame is rotatably connected to the outside of the limiting ring. The limiting frame is fixedly connected to the storage box. This step, by setting the limiting ring and the limiting frame, allows the side of the stirring rod away from the toothed ring to be further limited, thereby making the rotation of the stirring rod more stable and improving the stability of the device.

[0008] Preferably, a connecting plate is fixedly connected to the outside of the limiting frame, and a heating tube assembly is fixedly connected to the outside of the connecting plate. This step, by setting the connecting plate and the heating tube assembly, allows the plastic material to be heated by the heating tube assembly when the stirring rod stirs the plastic material, thereby making the plastic material less likely to solidify due to temperature drop during storage, and improving the stability of the device.

[0009] Preferably, a sealing frame is fixedly connected to the inner side of the storage box, and a sealing ring is fixedly connected to the inner side of the sealing frame. The sealing ring and the baffle are rotatably connected. This step, by setting the sealing frame and the sealing ring, further seals the space between the baffle and the storage box through the sealing frame, and further seals the space between the sealing frame and the baffle through the sealing ring. This makes it difficult for plastic material to leak out through the gap between the baffle and the storage box, thereby improving the sealing performance of the device.

[0010] Preferably, a filling block is fixedly connected to the outside of the sealing plate, and the filling block is used in conjunction with the metering tube. This step, by setting the filling block, allows for the insertion of filling blocks of different heights into the inside of the metering tube, thereby facilitating the adjustment of the space inside the metering tube at different positions. This allows for the injection of different volumes of plastic material into the inside of the metering tube at different positions according to the injection volume, thus improving the adjustability of the device's metering.

[0011] The advantages of this utility model are:

[0012] 1. This utility model, by setting up a baffle, a metering tube, a hydraulic cylinder, and a sealing plate, facilitates the metering of plastic material entering the metering tube due to the fixed volume of the space inside the metering tube. First, the hydraulic cylinder drives the sealing plate to press against the lower side of the metering tube, and then the plastic material is injected into the storage tank, so that the plastic material fills one metering tube along the through groove. Then, the baffle is rotated so that the through groove is away from the metering tube, and the sealing plate is moved down so that the metered plastic material enters the inside of the placement box, flows into the inside of the injection molding assembly through the placement box, and is then discharged through the injection molding assembly. When a larger dose of plastic material needs to be injected, the through groove can be moved to connect multiple metering tubes to fill multiple metering tubes, thereby expanding the metering range of the device. There is no need for manual metering of plastic material, thus improving the metering accuracy of the device.

[0013] 2. By incorporating a second motor, gears, a gear ring, and a stirring rod, this invention allows the second motor to drive the gears to rotate after the plastic material is injected into the storage tank. The gears then drive the gear ring to rotate, which in turn drives the stirring rod to rotate. The stirring rod further agitates and mixes the plastic material inside the storage tank, thereby removing air bubbles and ensuring more uniform mixing, thus improving the stability of the device.

Detailed Implementation

[0021] 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 scope of protection of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figures 1 to 5 As shown, a quantitative injection molding device includes a storage tank 1. A first motor 2 is fixedly connected to the outside of the storage tank 1. A baffle 3 is fixedly connected to the output end of the first motor 2. A through groove 4 is formed on the surface of the baffle 3. A quantitative tube 5 is connected to the inside of the storage tank 1. A placement box 6 is connected to the outside of the quantitative tube 5. An injection molding assembly 7 is connected to the outside of the placement box 6. A hydraulic cylinder 8 is fixedly connected to the outside of the placement box 6. A sealing plate 9 is fixedly connected to the output end of the hydraulic cylinder 8. The sealing plate 9 and the quantitative tube 5 work together. This step, by setting up the baffle 3, the quantitative tube 5, the hydraulic cylinder 8, and the sealing plate 9, facilitates the injection of plastic material into the inner side of the quantitative tube 5 because the internal space volume is fixed. To measure the amount of material, the hydraulic cylinder 8 first drives the sealing plate 9 to press against the lower side of the metering tube 5, and then injects plastic material into the storage box 1 so that the plastic material fills one metering tube 5 along the through groove 4. Then, the baffle 3 is rotated so that the through groove 4 moves away from the metering tube 5, and the sealing plate 9 is moved down so that the metered plastic material enters the placement box 6 and flows into the injection molding assembly 7 through the placement box 6. Then, the plastic material is discharged through the injection molding assembly 7. When a larger dose of plastic material needs to be injected, the through groove 4 can be moved to connect multiple metering tubes 5 to fill multiple metering tubes 5, thereby expanding the metering range of the device. There is no need for manual metering of plastic material, which improves the metering accuracy of the device.

[0024] Furthermore, such as Figure 1 and Figure 2As shown, a second motor 10 is fixedly connected to the outside of the storage tank 1. A gear 11 is fixedly connected to the output end of the second motor 10. A gear ring 12 meshes with the outside of the gear 11. The gear ring 12 is rotatably connected to the storage tank 1. A stirring rod 13 is fixedly connected to the outside of the gear ring 12. This step, by setting up the second motor 10, gear 11, gear ring 12 and stirring rod 13, allows the second motor 10 to drive the gear 11 to rotate after the plastic material is injected into the storage tank 1. The gear 11 then drives the gear ring 12 to rotate, and the gear ring 12 drives the stirring rod 13 to rotate. The stirring rod 13 further agitates and mixes the plastic material inside the storage tank 1, thereby removing air bubbles and making the mixing more uniform, thus improving the stability of the device.

[0025] Furthermore, such as Figure 1 As shown, a limiting ring 14 is fixedly connected to the outside of the stirring rod 13, and a limiting frame 15 is rotatably connected to the outside of the limiting ring 14. The limiting frame 15 is fixedly connected to the storage box 1. This step, by setting the limiting ring 14 and the limiting frame 15, allows the side of the stirring rod 13 away from the toothed ring 12 to be further limited, thereby making the rotation of the stirring rod 13 more stable and improving the stability of the device.

[0026] Furthermore, such as Figure 1 As shown, a connecting plate 16 is fixedly connected to the outside of the limiting frame 15, and a heating tube assembly 17 is fixedly connected to the outside of the connecting plate 16. This step, by setting the connecting plate 16 and the heating tube assembly 17, allows the stirring rod 13 to stir the plastic material, and the heating tube assembly 17 can heat the plastic material, thereby making the plastic material less likely to solidify due to temperature drop during storage, thus improving the stability of the device.

[0027] Furthermore, such as Figure 1 As shown, a sealing frame 18 is fixedly connected to the inner side of the storage box 1, and a sealing ring 19 is fixedly connected to the inner side of the sealing frame 18. The sealing ring 19 and the baffle 3 are rotatably connected. This step, by setting the sealing frame 18 and the sealing ring 19, further seals the space between the baffle 3 and the storage box 1 through the sealing frame 18, and further seals the space between the sealing frame 18 and the baffle 3 through the sealing ring 19. This makes it difficult for plastic material to overflow through the gap between the baffle 3 and the storage box 1, thereby improving the sealing performance of the device.

[0028] Furthermore, such as Figure 5As shown, a filling block 20 is fixedly connected to the outside of the sealing plate 9. The filling block 20 is used in conjunction with the metering tube 5. This step, by setting the filling block 20, allows for the insertion of filling blocks 20 of different heights into the inside of the metering tube 5, thereby facilitating the adjustment of the space inside the metering tube 5 at different positions. This allows for the injection of different volumes of plastic material into the inside of the metering tube 5 at different positions according to the injection volume, thus improving the adjustability of the device's metering.

[0029] Working principle: Since the volume of the space inside the metering tube 5 is fixed, it is convenient to meter the plastic material entering into it. First, the hydraulic cylinder 8 drives the sealing plate 9 to stick to the lower side of the metering tube 5. Then, the plastic material is injected into the storage box 1, so that the plastic material fills one metering tube 5 along the through groove 4. Then, the baffle 3 is rotated so that the through groove 4 is away from the metering tube 5. The sealing plate 9 is then moved down so that the metered plastic material enters the placement box 6 and flows into the injection molding assembly 7 through the placement box 6. The plastic material is then discharged through the injection molding assembly 7. When a larger dose of plastic material needs to be injected, the through groove 4 can be moved to connect multiple metering tubes 5 to fill multiple metering tubes 5. After injection, the sealing plate 9 is moved down again so that the plastic material is discharged and enters the injection molding assembly 7.
