Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to an air suction tube sleeve embedded in an injection mold. Background Technology

[0002] Most existing injection molds use horizontal opening and closing mechanisms. Due to space constraints, the injection surface of the lower mold is parallel to the upper mold, and the horizontal closing mechanism limits the mold's opening and closing range, resulting in a small operating space. This makes it difficult for operators to perform mold adjustments, cleaning, and inspections due to the limited space, increasing the difficulty of their work. Furthermore, the lower mold's parallel position is obstructed by the mold's structure, making it difficult for operators to directly observe the lower mold's condition. Utility Model Content

[0003] The purpose of this invention is to provide an air intake tube sleeve that can be embedded in an injection mold to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a suction tube sleeve embedded in an injection mold, comprising: Equipment rack; A rotating worktable is rotatably positioned on top of the equipment frame. A servo motor that drives the rotating worktable to rotate is installed inside the equipment frame. A lower mold is fixedly connected to the top of the rotating worktable. A fixing block is installed on the top of the lower mold. A positioning post two is slidably connected to the middle of the fixing block for positioning the end of the suction pipe. Two forming sliders are laterally arranged in the middle of the equipment frame and on both sides of the positioning post two. The upper mold is raised and lowered above the rotary worktable. The bottom of the upper mold is fixedly connected to an inclined plug that drives two forming sliders to close. The equipment frame is internally fixed with a hydraulic cylinder that drives the upper mold downward to close with the lower mold.

[0005] Preferably, a crossbeam is fixedly connected inside the equipment frame, a transmission pipe is fixedly connected to the bottom of the rotary worktable and rotatably connected to the crossbeam, a servo motor is fixedly connected to the bottom of the crossbeam, and the servo motor is connected to the transmission pipe through a gear set.

[0006] Preferably, a second lifting rod is slidably connected to the center of the rotary worktable, the second lifting rod passes through the middle of the crossbeam, and a first lifting rod is vertically slidably connected to the top of the equipment frame. The bottom of the first lifting rod and the bottom of the second lifting rod are fixedly connected by a metal plate.

[0007] Preferably, a support limiting plate is fixedly connected inside the equipment frame, and both the first and second lifting rods are slidably connected to the support limiting plate. A hydraulic cylinder three is fixedly connected to the top of the support limiting plate, and the output end of the hydraulic cylinder three is fixedly connected to a metal plate.

[0008] Preferably, a connecting plate is fixedly connected between the top of the first lifting rod and the top of the second lifting rod, and the upper mold is fixedly connected to the bottom of the connecting plate.

[0009] Preferably, a needle plate is raised and lowered in the middle of the lower mold, a hydraulic cylinder is fixedly connected to the bottom of the rotary worktable, the output end of the hydraulic cylinder is fixedly connected to the needle plate, an ejector pin is fixedly connected to the top of the needle plate, a lifting plate is fixedly connected to the bottom of the fixing block, and a positioning post is raised and lowered at the top of the lower mold. A mold cavity that mates with the positioning post is opened at the bottom of the upper mold, and both the positioning post and the lifting plate are fixedly connected to the ejector pin.

[0010] Preferably, a hydraulic cylinder is fixedly connected to the top of the lifting plate, a positioning post is fixedly connected to the output end of the hydraulic cylinder, a sliding rod is fixedly connected inside the lower mold, the forming slider is slidably installed on the outside of the sliding rod, an oblique hole that mates with the positioning post is opened on the top of the forming slider, a spring is sleeved on the outside of the sliding rod and between the two forming sliders, and a hole for accommodating the spring is opened at one end of the forming slider.

[0011] Compared with the prior art, the advantages of this utility model are: the rotary worktable can accurately rotate the lower mold to below the upper mold for mold closing operation, and can also rotate in the opposite direction to reset after injection molding; the hydraulic cylinder three drives the metal plate to rise and fall, which in turn drives the lifting rod one and lifting rod two to move downward in the middle of the support limit plate, ultimately enabling the upper mold and lower mold to cooperate to achieve mold closing; and the rotational misalignment of the upper and lower molds provides a large and unobstructed operating space, facilitating observation of the corresponding position of the lower mold and loading and unloading operations; during the mold closing process, the inclined insert is inserted into the inclined hole at the top of the forming slider, simultaneously pressing the two forming sliders towards the center.

The top of the lifting plate is fixedly connected to the first hydraulic cylinder, and the output end of the first hydraulic cylinder is fixedly connected to the second positioning post. During demolding, the second hydraulic cylinder drives the second positioning post and the first positioning post to return to their original positions upward through the pin plate and ejector pin. Then, the first hydraulic cylinder drives the second positioning post to retract, separating the second positioning post from the end of the suction pipe, further facilitating product demolding, preventing the product from sticking to the second positioning post, and ensuring the integrity of demolding and product quality.

[0014] 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.

[0015] Please see Figure 1 , 2As shown in Figures 3, 4, 5, 6, and 7, this utility model provides a technical solution: a suction pipe sleeve embedded in an injection mold, comprising: an equipment frame 1; a rotary worktable 2 rotatably mounted on the top of the equipment frame 1, a servo motor 21 for driving the rotary worktable 2 to rotate installed inside the equipment frame 1, the servo motor 21 being equipped with an encoder, a lower mold 15 fixedly connected to the top of the rotary worktable 2, a storage box fixedly connected to one side of the lower mold 15 for placing the suction pipe and preventing it from getting tangled with other workpieces, a lifting groove being provided on the top of the lower mold 15, and a lifting device being installed inside the lifting groove. The device is equipped with a fixing block 13, and a positioning column 14 is slidably connected to the middle of the fixing block 13 for positioning the end of the suction pipe. Two forming sliders 10 are laterally arranged in the middle of the device frame 1 and on both sides of the positioning column 14. The upper mold 6 is raised and lowered above the rotary worktable 2. The top of the upper mold 6 is connected to the extruder through a hose. The upper mold 6 has a flow channel that cooperates with the forming sliders 10. The bottom of the upper mold 6 is fixedly connected to an inclined insert 7 that drives the two forming sliders 10 to close. The device frame 1 is fixedly connected to a hydraulic cylinder 23 that drives the upper mold 6 downward to close with the lower mold 15.

[0016] It should be noted that this embodiment includes a controller and a corresponding operation panel. The controller controls the second positioning post 14 to extend forward, positioning its end above the molding slider 10. Then, one end of the suction pipe is inserted into the end of the second positioning post 14, placing the middle part of the suction pipe inside the storage box. The controller then controls the fixing block 13 to move downward. The fixing block 13 drives the second positioning post 14 to move downward, positioning the second positioning post 14 between the two molding sliders 10, with the ends of the second positioning post 14 and the molding slider 10 being concentrically arc-shaped. Then, the rotating worktable 2 rotates, causing the lower mold 15 to rotate below the upper mold 6. The upper mold 6 then moves downward to cooperate with the lower mold 15 to achieve mold closing. During the mold closing process, the inclined insertion 7 cooperates with the molding slider 10, causing the molding slider 10 to close towards the center. This cooperates with the upper mold 6 to form a ring structure outside the second positioning post 14, facilitating injection molding of the end of the suction pipe.

[0017] In one embodiment, a crossbeam is fixedly connected inside the equipment frame 1, and a transmission pipe is fixedly connected to the bottom of the rotating worktable 2 and rotatably connected to the crossbeam. A servo motor 21 is fixedly connected to the bottom of the crossbeam, and the servo motor 21 is connected to the transmission pipe through a gear set.

[0018] It should be noted that in this embodiment, when the rotary worktable 2 is driven to rotate, the servo motor 21 drives the driven gear to rotate through the driving gear, the driven gear drives the transmission tube to rotate, and the transmission tube drives the rotary worktable 2 to rotate. In this way, with the cooperation of the encoder, the lower mold 15 is rotated to correspond with the connecting plate 5, and the reverse rotation is performed after the injection molding is completed.

[0019] In one embodiment, a second lifting rod 4 is slidably connected to the center of the rotary worktable 2, passing through the middle of the crossbeam. A first lifting rod 3 is vertically slidably connected to the top of the equipment frame 1. The bottom of the first lifting rod 3 and the bottom of the second lifting rod 4 are fixedly connected by a metal plate. A support limiting plate 24 is fixedly connected inside the equipment frame 1. Both the first lifting rod 3 and the second lifting rod 4 are slidably connected to the support limiting plate 24. A third hydraulic cylinder 23 is fixedly connected to the top of the support limiting plate 24. The output end of the third hydraulic cylinder 23 is fixedly connected to the metal plate. A connecting plate 5 is fixedly connected between the top of the first lifting rod 3 and the top of the second lifting rod 4. The upper mold 6 is fixedly connected to the bottom of the connecting plate 5.

[0020] It should be noted that, in this embodiment, when the connecting plate 5 is raised or lowered, since the support limiting plate 24 is fixed to the equipment frame 1, the metal plate is raised or lowered by the hydraulic cylinder 23. The metal plate drives the lifting rod 3 and the lifting rod 4 to move downward in the middle of the support limiting plate 24. The lifting rod 3 and the lifting rod 4 drive the connecting plate 5 to move downward. The connecting plate 5 drives the upper mold 6 to move downward and cooperate with the lower mold 15, thereby realizing mold closing.

[0021] In one embodiment, a needle plate 17 is raised and lowered in the middle of the lower mold 15, a hydraulic cylinder 22 is fixedly connected to the bottom of the rotary worktable 2, the output end of the hydraulic cylinder 22 is fixedly connected to the needle plate 17, an ejector pin 18 is fixedly connected to the top of the needle plate 17, a lifting plate 16 is fixedly connected to the bottom of the fixing block 13, a positioning post 9 is raised and lowered at the top of the lower mold 15, a mold cavity 8 that mates with the positioning post 9 is opened at the bottom of the upper mold 6, the positioning post 9 and the lifting plate 16 are both fixedly connected to the ejector pin 18, a hydraulic cylinder 12 is fixedly connected to the top of the lifting plate 16, a positioning post 14 is fixedly connected to the output end of the hydraulic cylinder 12, a slide rod 19 is fixedly connected inside the lower mold 15, a forming slider 10 is slidably installed on the outside of the slide rod 19, an oblique hole 11 that mates with the positioning post 9 is opened at the top of the forming slider 10, a spring 20 is sleeved on the outside of the slide rod 19 and located between the two forming sliders 10, and a hole for accommodating the spring 20 is opened at one end of the forming slider 10.

[0022] It should be noted that in this embodiment, one end of the suction pipe is inserted into the end of the second positioning post 14, and the other end of the suction pipe is inserted into the outside of the first positioning post 9. The needle plate 17 is driven to move downward by the second hydraulic cylinder 22. The needle plate 17 drives the lifting plate 16 to move downward along with the first positioning post 9 through the ejector pin 18, so that the first positioning post 9 is placed downward inside the semi-circular groove structure. The lifting plate 16 drives the second positioning post 14 to be placed between the two molding sliders 10 through the fixing block 13. In this way, when the mold is closed, the semi-circle at the bottom of the upper mold 6 matches the corresponding position of the first positioning post 9, so that a ring structure can be injection molded on the outside of the first positioning post 9. During the mold closing process, the inclined insert 7 is inserted into the inclined hole 11 from the top of the molding slider 10, so that the two molding sliders 10 are simultaneously moved towards the center. During the extrusion process, the molding slider 10 slides outside the slide bar 19 and compresses the spring 20, thereby forming a ring structure on the outside of the positioning post 2 14. This allows for the injection molding of the ring structure on the outside of the positioning post 2 14. During mold separation, the spring 20 pushes the two molding sliders 10 to both sides. Then, the hydraulic cylinder 22 drives the positioning post 2 14 and the positioning post 1 9 to return upward through the needle plate 17 and the ejector pin 18. The hydraulic cylinder 12 then drives the positioning post 2 14 to retract, thereby separating the positioning post 2 14 from the end of the suction pipe.
