Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and more specifically, to an injection mold that prevents material overflow. Background Technology

[0002] Injection molding is a manufacturing method that combines injection and molding technologies. Its significant advantages include a high-speed and efficient production process, easy automation, diverse product styles, flexible shape design, wide range of sizes and high precision, and the ability to quickly iterate and update products. It can also mold complex parts. This molding method is particularly suitable for the manufacturing needs of large-scale production and complex-shaped products. Injection molds are an indispensable key piece of equipment for realizing this process.

[0003] The working principle of injection molds is based on the thermoplastic or thermosetting properties of plastics. During the injection molding process, the mold clamping device of the injection molding machine pushes the moving mold towards the fixed mold until the moving mold and the fixed mold are tightly closed, forming a closed cavity. However, in general injection molds, the gap between the upper and lower molds can lead to overflow. Traditional devices prevent overflow by installing sealing strips on the edge of the injection cavity. Although the sealing strips are deformable, they can result in poor sealing between the upper and lower molds during use. Therefore, improvements and optimizations are needed. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides an injection mold that prevents overflow, which has the advantages of preventing overflow and easy removal.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an injection mold for preventing material spillage, comprising a lower mold and an upper mold, wherein the upper mold is movably disposed above the lower mold;

[0006] The lower mold has a first groove inside, and an airbag is fixedly installed at the bottom of the inner side of the first groove. The side of the airbag is fixedly connected to the inner side of the first groove. The lower mold also has a second groove inside, and a high-temperature sealing airbag is fixedly installed at the bottom of the inner side of the second groove. The side of the high-temperature sealing airbag is fixedly connected to the side of the second groove. One side of the high-temperature sealing airbag is movably connected to the upper mold. A connecting pipe is fixedly connected to one side of the airbag, and one end of the connecting pipe extends into the interior of the high-temperature sealing airbag.

[0007] As a preferred technical solution of this utility model, a groove three is provided at the bottom of the inner side of the lower mold, a gear two is rotatably installed at the bottom of the inner side of the groove three, a threaded rod is fixedly installed above the gear two, a threaded sleeve is threaded on the outer surface of the threaded rod, one end of the threaded sleeve extends to the top of the lower mold and a top plate is fixedly installed thereon, a rubber pad is fixedly installed above the top plate, the top of the side of the rubber pad is fixedly connected to the lower mold, and a drive mechanism is fixedly installed on one side inside the groove three.

[0008] As a preferred embodiment of this utility model, side plates one are fixedly installed on both the left and right sides of the lower mold, and side plates two are fixedly installed on both the left and right sides of the upper mold.

[0009] As a preferred embodiment of this utility model, a telescopic cylinder is fixedly installed on the upper part of the first side plate, and the top of the telescopic cylinder is fixedly connected to the bottom of the second side plate.

[0010] As a preferred embodiment of this utility model, the driving mechanism includes a connecting block fixedly disposed on one side inside the groove three, a motor fixedly installed at the bottom of the connecting block, and a gear one fixedly installed above the drive shaft of the motor.

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

[0014] 1. This utility model uses a telescopic cylinder to move the upper mold downwards, causing the bottom of the upper mold to contact the air bladder. When the bottom of the upper mold contacts the air bladder, the air bladder is compressed, causing it to deform. The gas inside the air bladder enters the interior of the high-temperature sealing air bladder through the connecting pipe, causing the high-temperature sealing air bladder to deform and tightly fit the connection between the lower mold and the upper mold. Compared with traditional devices, this device seals the connection between the lower mold and the upper mold, preventing the injection liquid inside the lower mold and the upper mold from flowing out and avoiding overflow, thereby improving the working efficiency of the device.

[0015] 2. This utility model uses a starting motor to drive the rotation of gear one. When gear one rotates, it drives the rotation of gear two. The rotation of gear two drives the threaded rod to rotate, thereby causing the threaded sleeve to move upward and driving the top plate to rise. This causes the rubber pad to move upward and remove the model. Compared with traditional devices, this device improves the efficiency of removing the model by removing it, thereby improving the working efficiency of the device and making it easier to remove the model from the device.

[0024] 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.

[0025] like Figures 1 to 7As shown, this utility model provides an injection mold for preventing material spillage, including a lower mold 1 and an upper mold 5, with the upper mold 5 movably disposed above the lower mold 1;

[0026] The lower mold 1 has a groove 7 inside, and an airbag 8 is fixedly installed at the bottom of the inner side of the groove 7. The side of the airbag 8 is fixedly connected to the inner side of the groove 7. The lower mold 1 has a groove 9 inside, and a high-temperature sealing airbag 10 is fixedly installed at the bottom of the inner side of the groove 9. The side of the high-temperature sealing airbag 10 is fixedly connected to the side of the groove 9. One side of the high-temperature sealing airbag 10 is movably connected to the upper mold 5. A connecting pipe 11 is fixedly connected to one side of the airbag 8. One end of the connecting pipe 11 extends into the interior of the high-temperature sealing airbag 10.

[0027] When the operator uses it, the operator first activates the telescopic cylinder 3 to move the upper mold 5 downward. When the upper mold 5 moves downward, the bottom of the upper mold 5 will contact the airbag 8. When the upper mold 5 contacts the airbag 8, it will compress the airbag 8 downward. When the airbag 8 is compressed downward, it will deform. At this time, the gas inside the airbag 8 will enter the interior of the high-temperature sealing airbag 10 through the connecting pipe 11. When the gas inside the airbag 8 enters the interior of the high-temperature sealing airbag 10, it will deform the high-temperature sealing airbag 10, thereby making the high-temperature sealing airbag 10 tightly fit with the connection between the lower mold 1 and the upper mold 5.

[0028] By activating the telescopic cylinder 3, the upper mold 5 is moved downward, causing the bottom of the upper mold 5 to contact the airbag 8. When the bottom of the upper mold 5 contacts the airbag 8, the airbag 8 is compressed, causing it to deform. The gas inside the airbag 8 enters the interior of the high-temperature sealing airbag 10 through the connecting pipe 11, causing the high-temperature sealing airbag 10 to deform and tightly fit the connection between the lower mold 1 and the upper mold 5. Compared with the traditional device, this device seals the connection between the lower mold 1 and the upper mold 5, preventing the injection liquid inside the lower mold 1 and the upper mold 5 from flowing out and avoiding overflow, thereby improving the working efficiency of the device.

[0029] The lower mold 1 has a groove 3 12 at the bottom of its inner side. A gear 2 16 is rotatably mounted at the bottom of the groove 3 12. A threaded rod 17 is fixedly mounted above the gear 2 16. A threaded sleeve 18 is threaded onto the outer surface of the threaded rod 17. One end of the threaded sleeve 18 extends to the top of the lower mold 1 and is fixedly mounted on a top plate 19. A rubber pad 20 is fixedly mounted on the top of the top plate 19. The top of the side of the rubber pad 20 is fixedly connected to the lower mold 1. A drive mechanism is fixedly mounted on one side inside the groove 3 12.

[0030] When the operator uses the device, they first start the motor 14. Once the motor 14 starts, it drives the first gear 15 to rotate. When the first gear 15 rotates, it meshes with the second gear 16, causing the second gear 16 to rotate as well. When the second gear 16 rotates, it drives the threaded rod 17 to rotate. When the threaded rod 17 rotates, it is threadedly connected to the threaded sleeve 18, causing the threaded sleeve 18 to move upward. When the threaded sleeve 18 moves upward, it drives the top plate 19 to move upward. When the top plate 19 moves upward, it drives the bottom of the rubber pad 20 to move upward, thus pushing out the molded model.

[0031] By starting the motor 14, the first gear 15 is driven to rotate. When the first gear 15 rotates, it drives the second gear 16 to rotate. The rotation of the second gear 16 drives the threaded rod 17 to rotate, thereby causing the threaded sleeve 18 to move upward and drive the top plate 19 to rise. This causes the rubber pad 20 to move upward and remove the model. Compared with the traditional device, this device improves the efficiency of removing the model by removing the model, thereby improving the working efficiency of the device and making it easier to remove the model from the device.

[0032] The lower mold 1 has side plates 2 fixedly installed on both its left and right sides, and the upper mold 5 has side plates 4 fixedly installed on both its left and right sides.

[0033] The design of side plate 1 (2) and side plate 2 (4) facilitates the movement of the upper mold 5, improving the ease of operation of the device.

[0034] A telescopic cylinder 3 is fixedly installed on the upper part of side plate 2, and the top of the telescopic cylinder 3 is fixedly connected to the bottom of side plate 4.

[0035] The design of the telescopic cylinder 3 facilitates the movement of the upper mold 5 and provides power for the movement of the upper mold 5.

[0036] The drive mechanism includes a connecting block 13 fixedly disposed on one side inside the groove 12, a motor 14 fixedly mounted on the bottom of the connecting block 13, and a gear 15 fixedly mounted on the drive shaft of the motor 14.

[0037] By starting the motor 14, the first gear 15 is driven to rotate, which in turn drives the second gear 16 to rotate.

[0038] The upper mold 5 has an injection hole 6 at its top, and the bottom of the injection hole 6 extends through the upper and lower sides of the upper mold 5.

[0039] The design of the injection hole 6 makes it easy for workers to add injection liquid into the lower mold 1 and the upper mold 5.

[0040] Among them, gear 15 is located on one side of gear 2 16, and gear 2 16 meshes with gear 15.

[0041] The meshing of gear 15 and gear 2 16 enables gear 15 to drive gear 2 16 to rotate when it rotates.

[0042] Working principle and usage process of this utility model:

[0043] When the operator uses it, the operator first activates the telescopic cylinder 3 to move the upper mold 5 downward. When the upper mold 5 moves downward, the bottom of the upper mold 5 will contact the airbag 8. When the upper mold 5 contacts the airbag 8, it will compress the airbag 8 downward. When the airbag 8 is compressed downward, it will deform. At this time, the gas inside the airbag 8 will enter the interior of the high-temperature sealing airbag 10 through the connecting pipe 11. When the gas inside the airbag 8 enters the interior of the high-temperature sealing airbag 10, it will deform the high-temperature sealing airbag 10, thereby making the high-temperature sealing airbag 10 tightly fit with the connection between the lower mold 1 and the upper mold 5.

[0044] When the operator uses the device, they first start the motor 14. Once the motor 14 starts, it drives the first gear 15 to rotate. When the first gear 15 rotates, it meshes with the second gear 16, causing the second gear 16 to rotate as well. When the second gear 16 rotates, it drives the threaded rod 17 to rotate. When the threaded rod 17 rotates, it is threadedly connected to the threaded sleeve 18, causing the threaded sleeve 18 to move upward. When the threaded sleeve 18 moves upward, it drives the top plate 19 to move upward. When the top plate 19 moves upward, it drives the bottom of the rubber pad 20 to move upward, thus pushing out the molded model.
