Description

Technical Field

[0001] This utility model belongs to the field of plastic bucket injection molding technology, and more specifically, it relates to an injection mold for plastic buckets. Background Technology

[0002] Plastic buckets are a common type of packaging container, widely used in various fields. The main process for producing plastic buckets is injection molding, which involves injecting molten plastic into a mold and then cooling it to form a plastic bucket.

[0003] In existing technology, plastic buckets are generally injection molded by combining an upper mold and a lower mold. However, when removing the finished plastic bucket from the inside of the mold, workers need to reach inside the upper and lower molds to remove the plastic bucket, which is time-consuming and labor-intensive. Utility Model Content

[0004] To address the problem that when plastic buckets are injection molded using a combination of upper and lower molds, workers need to reach inside the upper and lower molds to remove the finished plastic buckets, which is time-consuming and labor-intensive, this utility model proposes an injection mold for plastic buckets to overcome the aforementioned technical problems in existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an injection mold for a plastic bucket, comprising a shell:

[0007] The housing is respectively equipped with a drive assembly, a moving assembly, a moving mold assembly, a limiting assembly, and an ejection assembly;

[0008] A drive component, the output end of which is fixedly installed at one end of a moving component, so that the drive component drives the moving component to move;

[0009] The bottom end of the moving mold assembly is fixedly installed to the top end of the movable assembly so that the moving assembly drives the moving mold assembly to move when the movable assembly moves.

[0010] A limiting component is fixedly installed at its top end and at the bottom end of the moving component, so that the limiting component restricts the movement direction of the moving component;

[0011] The ejector assembly has its outer surface slidably disposed with the interior of the moving mold assembly so that the ejector assembly demolds the plastic bucket on the moving mold assembly.

[0012] Furthermore, the drive assembly includes a mounting bracket, the top of which is fixedly mounted to the inside of the housing, and a motor is fixedly mounted on one side of the mounting bracket.

[0013] Furthermore, the moving component includes a mounting base, the top of which is fixedly mounted to the inside of the housing. A threaded rod is rotatably provided inside the mounting base, one end of which is fixedly mounted to the output end of the motor. A moving block is threadedly connected to the threaded surface of the threaded rod, and a moving stage is fixedly connected to the top of the moving block.

[0014] Furthermore, the moving mold assembly includes a support column and a lower mold. The bottom end of the support column is fixedly installed to the top end of the housing. A support plate is fixedly installed to the top end of the support column. A cylinder is fixedly installed to the top end of the support plate. An installation plate is fixedly installed to the telescopic end of the cylinder. An upper mold is fixedly installed to the bottom end of the installation plate. The bottom end of the lower mold is fixedly installed to the top end of the moving stage.

[0015] Furthermore, the limiting component includes a fixed base, the top of which is fixedly installed inside the housing, a limiting rod is fixedly connected to one side of the fixed base, a limiting block is slidably provided on the outer surface of the limiting rod, and the top of the limiting block is fixedly installed to the bottom of the moving stage.

[0016] Furthermore, the ejection assembly includes an ejector rod, the outer surface of which is slidably disposed with respect to the interior of the moving table and the lower mold, a top plate is fixedly connected to the top of the ejector rod, a connecting plate is fixedly connected to the outer surface of the ejector rod, a tension spring is fixedly connected to the top of the connecting plate, and the bottom end of the tension spring is fixedly connected to the top of the moving table.

[0017] Furthermore, the ejection assembly also includes a support frame, the top of which is fixedly installed inside the housing. A guide rail is fixedly installed on the top of the support frame, and a roller is rotatably mounted on the top of the guide rail. The top of the roller is fixedly installed on the bottom of the ejector rod.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model uses a drive component to drive a movable component installed at the output end to move. When the movable component moves, it can drive the moving mold component installed at the top to move, so that the moving mold component can drive the injection-molded plastic bucket to move. When the moving mold component moves, it can drive the ejector component that is slidably set inside to move. When the ejector component moves, it can move slowly upward, thereby pushing the plastic bucket on the outer surface of the moving mold component upward, which makes it easier to remove the plastic bucket from the outer surface of the moving mold component, thus facilitating the demolding of the plastic bucket, which is more time-saving and labor-saving.

[0020] 2. This utility model uses a moving platform to move the lower mold, which in turn moves the internally sliding push rods. The push rods then move the rollers fixed at their bottom ends. Since the outer surface of the rollers rolls against the top of the guide rail, and the guide rail is inclined, the rollers move in a gradually rising trajectory as they follow the guide rail. This causes the rollers to move the push rods upwards. When the push rods move upwards, they move the top plate fixed at the top, thus pushing the plastic bucket, which is attached to the outer surface of the lower mold, upwards. This allows for demolding of the plastic bucket from the lower mold, facilitating demolding and unloading, saving time and effort.

[0021] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0032] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0033] Please see Figures 1-6 As shown, this utility model is an injection mold for a plastic bucket, including a shell 1:

[0034] The housing 1 is respectively provided with a drive assembly 2, a moving assembly 3, a moving mold assembly 4, a limiting assembly 5, and an ejection assembly 6;

[0035] The output end of the drive component 2 is fixedly installed at one end of the moving component 3 so that the drive component 2 drives the moving component 3 to move.

[0036] The bottom end of the moving mold assembly 4 is fixedly installed with the top end of the moving assembly 3 so that the moving assembly 3 drives the moving mold assembly 4 to move when it moves.

[0037] The limiting component 5 is fixedly installed at its top end to the bottom end of the moving component 3 so that the limiting component 5 restricts the moving direction of the moving component 3.

[0038] Ejector assembly 6 has its outer surface slidably disposed with the interior of moving mold assembly 4 so that ejector assembly 6 demolds the plastic bucket on moving mold assembly 4.

[0039] In use, the moving mold assembly 4 is activated to injection mold the plastic bucket. After injection molding is completed, the moving mold assembly 4 is activated again to separate the parts. Then, the drive assembly 2 is activated to drive the moving assembly 3 installed at the output end to move. This causes the moving assembly 3 to move the limiting assembly 5 installed at the bottom end and move along the direction of the limiting assembly 5. At the same time, when the moving assembly 3 moves, it can drive the moving mold assembly 4 installed at the top to move, so that the moving mold assembly 4 can move the injection-molded plastic bucket. When the moving mold assembly 4 moves, it can drive the ejector assembly 6, which is slidably set inside, to move. When the ejector assembly 6 moves, it can move slowly upward, thereby pushing the plastic bucket on the outer surface of the moving mold assembly 4 upward, making it easy to remove the plastic bucket from the outer surface of the moving mold assembly 4.

[0040] This invention uses a drive assembly 2 to drive a movable assembly 3 installed at the output end to move. When the movable assembly 3 moves, it drives the moving mold assembly 4 installed at the top to move, so that the moving mold assembly 4 moves the injection-molded plastic bucket. When the moving mold assembly 4 moves, it drives the ejector assembly 6, which is slidably installed inside, to move. When the ejector assembly 6 moves, it moves slowly upward, thereby pushing the plastic bucket on the outer surface of the moving mold assembly 4 upward, making it easier to remove the plastic bucket from the outer surface of the moving mold assembly 4, thus facilitating demolding of the plastic bucket, which is more time-saving and labor-saving.

[0041] In one embodiment, the drive assembly 2 includes a mounting bracket 201, the top of which is fixedly mounted to the inside of the housing 1, and a motor 202 is fixedly mounted on one side of the mounting bracket 201.

[0042] The mounting bracket 201 is designed to support the motor 202 mounted on one side, ensuring that the motor 202 can operate stably.

[0043] In one embodiment, the moving component 3 includes a mounting base 301, the top end of which is fixedly mounted to the inside of the housing 1. A threaded rod 302 is rotatably provided inside the mounting base 301. One end of the threaded rod 302 is fixedly mounted to the output end of the motor 202. A moving block 303 is threadedly connected to the threaded surface of the threaded rod 302. A moving stage 304 is fixedly connected to the top end of the moving block 303.

[0044] The threaded rod 302 installed at the output end is driven to rotate by the starting motor 202. Since the threaded surface of the threaded rod 302 is connected to the internal thread of the moving block 303, and the top of the moving block 303 is fixedly connected to the moving platform 304, when the threaded rod 302 rotates, it can drive the moving block 303 to move, so that the moving block 303 drives the moving platform 304 to move. Since the bottom end of the moving platform 304 is in contact with the top end of the housing 1, it can restrict the moving block 303 and prevent it from rotating with the rotation of the threaded rod 302, thereby improving the stability of the moving block 303 during operation.

[0045] In one embodiment, the moving mold assembly 4 includes a support column 401 and a lower mold 402. The bottom end of the support column 401 is fixedly installed with the top end of the housing 1. A support plate 403 is fixedly installed with the top end of the support column 401. A cylinder 404 is fixedly installed with the top end of the support plate 403. An installation plate 405 is fixedly installed with the telescopic end of the cylinder 404. An upper mold 406 is fixedly installed with the bottom end of the installation plate 405. The bottom end of the lower mold 402 is fixedly installed with the top end of the moving stage 304.

[0046] The mounting plate 405, which is installed at the telescopic end, is moved by starting the cylinder 404. Since the inside of the mounting plate 405 is slidably set with the outer surface of the support column 401, and the bottom end of the mounting plate 405 is fixedly installed with the top end of the upper mold 406, when the mounting plate 405 moves, it can drive the upper mold 406 to move downward along the direction of the support column 401, so that the inside of the upper mold 406 and the outer surface of the lower mold 402 are closed. Then, the molten plastic is injected into the closed mold to form a plastic bucket. After the injection is completed, the cylinder 404 is started again to cooperate with the mounting plate 405 to drive the upper mold 406 to move upward, so that the formed plastic bucket is in contact with the outer surface of the lower mold 402.

[0047] Since the bottom end of the lower mold 402 is fixedly installed with the top end of the moving table 304, when the moving table 304 moves with the moving block 303, the moving table 304 can drive the lower mold 402 to move, so that the lower mold 402 moves out of the mold closing range, thereby facilitating the unloading of the plastic bucket that is attached to the outer surface of the lower mold 402.

[0048] In one embodiment, the limiting component 5 includes a fixed base 501, the top of the fixed base 501 is fixedly installed inside the housing 1, a limiting rod 502 is fixedly connected to one side of the fixed base 501, a limiting block 503 is slidably provided on the outer surface of the limiting rod 502, and the top of the limiting block 503 is fixedly installed at the bottom of the moving stage 304.

[0049] When the moving stage 304 moves, it can drive the limiting block 503 installed at the bottom to move as well. Since the inside of the limiting block 503 is slidably set with the outer surface of the limiting rod 502, and both ends of the limiting rod 502 are fixedly connected to one side of the fixed base 501, when the limiting block 503 moves, it can move along the direction of the limiting rod 502, so as to restrict the movement direction of the limiting block 503 and thus improve the stability of the moving stage 304 during the movement process.

[0050] In one embodiment, the ejection assembly 6 includes an ejector rod 601. The outer surface of the ejector rod 601 is slidably disposed with the inside of the moving table 304 and the lower mold 402, respectively. The top end of the ejector rod 601 is fixedly connected to a top plate 602. The outer surface of the ejector rod 601 is fixedly connected to a connecting plate 603. The top end of the connecting plate 603 is fixedly connected to a tension spring 604. The bottom end of the tension spring 604 is fixedly connected to the top end of the moving table 304.

[0051] The ejector assembly 6 also includes a support frame 605, the top of which is fixedly installed inside the housing 1. A guide rail 606 is fixedly installed on the top of the support frame 605, and a roller 607 is slidably installed on the top of the guide rail 606. The top of the roller 607 is fixedly installed on the bottom of the ejector rod 601.

[0052] When the moving table 304 moves the lower mold 402, it can move the internally sliding ejector rods 601, causing the ejector rods 601 to move the rollers 607 fixed at their bottom ends. Since the outer surface of the rollers 607 rolls against the top of the guide rail 606, and the guide rail 606 is inclined, when the rollers 607 move along the direction of the guide rail 606, their movement trajectory gradually rises. This allows the rollers 607 to move the ejector rods 601 upwards. When the ejector rods 601 move upwards, they can move the top plate 602 fixed at its top end. This causes the plastic bucket, which is attached to the outer surface of the lower mold 402, to be pushed upwards, so that the plastic bucket can be demolded from the lower mold 402. At the same time, when the ejector rod 601 moves upwards, it can drive the connecting plate 603 fixed on the outer surface to move synchronously. This allows the connecting plate 603 to drive the tension spring 604 fixed at the bottom to stretch. Then, when the moving table 304 drives the lower mold 402 to reset, the tension spring 604 can gradually retract the tension force, so that the tension spring 604 can cooperate with the connecting plate 603 to drive the ejector rod 601 to reset, so as to facilitate the subsequent production and processing of the plastic bucket.

[0053] Through the above technical solution, 1. The moving component 3 installed at the output end is driven by the start-up drive component 2 to move. When the moving component 3 moves, it can drive the moving mold component 4 installed at the top to move, so that the moving mold component 4 can drive the plastic bucket that has been injected and molded to move. When the moving mold component 4 moves, it can drive the ejector component 6 that is slidably set inside to move. When the ejector component 6 moves, it can move upward slowly, so that it can push the plastic bucket on the outer surface of the moving mold component 4 upward, thereby making it easier to remove the plastic bucket from the outer surface of the moving mold component 4, and thus making it easier to demold the plastic bucket, which is more time-saving and labor-saving.

[0054] 2. The lower mold 402 is moved by the moving table 304, which in turn moves the internally sliding ejector rod 601. The ejector rod 601 moves the roller 607 fixed at the bottom. Since the outer surface of the roller 607 rolls with the top of the guide rail 606 and the guide rail 606 is inclined, the roller 607 moves along the direction of the guide rail 606, and its movement trajectory gradually rises. This allows the roller 607 to move the ejector rod 601 upward. When the ejector rod 601 moves upward, it moves the top plate 602 fixed at the top, which pushes the plastic bucket that is attached to the outer surface of the lower mold 402 upward, so that the plastic bucket is demolded from the lower mold 402. This facilitates demolding and unloading of the plastic bucket, which is more time-saving and labor-saving.
