Description

Technical Field

[0001] This utility model relates to the field of rubber core injection technology, specifically a rubber core injection connection device. Background Technology

[0002] Currently, in the production of rubber hoses, the forming process typically employs a soft-core method, using a rubber core as the inner core to control the hose's inner diameter. On one hand, because the produced hoses need to be cut according to specifications, the rubber core inside the hose cannot be avoided being cut as well. If the cut rubber core is too short, it cannot be reused, resulting in significant resource waste. On the other hand, continuous production of long-meter hoses requires a high degree of precision in the length of the rubber core, and rubber cores obtained through ordinary production methods cannot meet this requirement.

[0003] However, existing technologies still have significant shortcomings, such as:

[0004] In the existing technology, the glue injection connection device usually adopts a single fixed structure to limit and fix the limiting mold during injection molding. This can lead to the fasteners loosening after long-term use. As a result, the glue injection connection device will expand internally during glue injection, causing the glue injection mold to shift or shake, resulting in insufficient glue adhesion and affecting the glue injection connection of the rubber core.

[0023] 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.

[0024] Please see Figures 1-5 This utility model provides a technical solution: a rubber core injection connection device, including a base plate 1, a frame 4, an injection gun 5, a storage box 6, an injection pipe 11, an injection pump 12 and a top plate 13. The top two sides of the base plate 1 are provided with limiting components 2 for limiting the mold mechanism. The limiting components 2 include vertical plates 21, and the bottom of the vertical plates 21 is fixedly connected to the top two sides of the base plate 1.

[0025] Example 1:

[0026] A second electric telescopic rod 22 is fixedly installed at the middle of the outer side of the vertical plate 21 by bolts. The output end of the second electric telescopic rod 22 is fixedly connected to a movable frame 23 by bolts. A motor 27 is fixedly installed on the outer side of the movable frame 23 by bolts. A threaded rod 25 is fixedly connected to the output end of the motor 27. A threaded sleeve 24 is threadedly connected to the surface of the threaded rod 25. A support rod 28 is fixedly connected to the outer side of the threaded sleeve 24. A limit block 210 is fixedly connected to the surface of the support rod 28.

[0027] In this embodiment: the second electric telescopic rod 22 is used to drive the movable frame 23 to move left and right. The movable frame 23 drives the motor 27 and the limiting block 210 to move. The motor 27 drives the threaded rod 25 to rotate. The threaded rod 25 drives the threaded sleeves 24 on both sides to move inward. The threaded sleeves 24 drive the support rod 28 and the limiting block 210 to move inward to fix and limit the mold. The second electric telescopic rod 22 and the motor 27 are both controlled by an external controller and powered by an external power supply. The surface of the threaded rod 25 is provided with positive and negative threads.

[0028] The inner side of the movable frame 23 is provided with a sliding guide groove 29, and a sliding guide block 26 is slidably connected to the inner cavity of the sliding guide groove 29. The inner side of the sliding guide block 26 is fixedly connected to the surface of the threaded sleeve 24. Support legs are fixedly connected to the left and right sides of the bottom of the base plate 1, and anti-slip pads are provided at the bottom of the support legs.

[0029] In this embodiment, the sliding guide block 26 slides within the inner cavity of the sliding guide groove 29. During the sliding process, the sliding guide block 26 can limit the rotation of the threaded sleeve 24 in the opposite direction, thus preventing the threaded sleeve 24 from rotating on its own during the rotation process.

[0030] Example 2:

[0031] Based on Embodiment 1, this embodiment takes into account that although Embodiment 1 can achieve the fixed clamping and limiting of the mold, the threads on the surface of the threaded rod 25 will wear during actual use, which will lead to a decrease in fixing efficiency and abnormal movement of the limiting block 210. This embodiment uses the following mechanism to detect the shaking of the limiting block 210.

[0032] An alarm component 3 for detecting and alarming the limit component 2 is provided on the outside of the frame 4. The alarm component 3 includes a fixing sleeve 31. The inner cavity of the fixing sleeve 31 is fixedly connected to the surface of the support rod 28. An infrared sensor 35, a fixing rod 34, and a detection block 33 are fixedly connected to the top of the fixing sleeve 31 by bolts. A display 37 is electrically connected to one side of the infrared sensor 35 by a wire. The inner side of the display 37 is bolted to the outside of the frame 4 by a mounting plate 36. An alarm 38 is electrically connected to the top of the display 37 by a wire. An alarm light 32 is provided on the top of the alarm 38.

[0033] In this embodiment: the infrared sensor 35 can continuously detect the position of the detection block 33 and display the detected data through the display 37. At the same time, the alarm 38 is used to compare the data displayed on the display 37. When the data comparison is abnormal, the alarm light 32 starts to work and emits sound and light to alarm, which can effectively alert to abnormalities that occur during the glue injection process and prevent operators from failing to detect them in time. The alarm light 32, the alarm 38, the display 37 and the infrared sensor 35 are all powered by an external power supply.

[0034] Example 3:

[0035] A frame 4 is fixedly connected to both sides of the top of the base plate 1. A top plate 13 is fixedly connected to the top of the inner side of the frame 4. A storage box 6 is fixedly connected to the top of the top plate 13. A glue pump 12 is fixedly installed on one side of the storage box 6 by bolts. A glue gun 5 is fixedly connected to the output end of the glue pump 12 through a glue pipe 11. The top of the glue gun 5 is magnetically connected to the bottom of the frame 4. Two first electric telescopic rods 8 are fixedly connected to the bottom of the outer side of the frame 4 by bolts. Two mold bodies 9 are fixedly connected to the output end of the first electric telescopic rods 8 by bolts. A glue injection hole 10 is opened on the top of each of the two mold bodies 9. A feed pipe 7 is fixedly connected to the middle of the top of the storage box 6. A cover plate is movably connected to the top of the feed pipe 7.

[0036] In this embodiment: the mold body 9 is selected according to the specific usage requirements. The mold body 9 is fixed to the output end of the first electric telescopic rod 8 by bolts. The first electric telescopic rod 8 drives the mold body 9 and the rubber core inside the mold body 9 to move and close the mold. The glue pump 12 is started to deliver glue to the inner cavity of the glue gun 5. The glue gun 5 is held and aligned with the glue injection hole 10 to perform glue injection. The first electric telescopic rod 8 and the glue pump 12 are both controlled by an external controller and powered by an external power supply.

[0037] Working principle: The type or style of mold body 9 is selected according to the on-site usage requirements. The mold body 9 is fixed to the first electric telescopic rod 8 with bolts. The rubber core to be processed is placed inside the mold body 9. The first electric telescopic rod 8 drives the mold body 9 to move inward, closing the mold bodies 9 on both sides. The operator holds the glue injection gun 5 and aligns it with the glue injection hole 10. The glue pump 12 extracts the glue from the storage tank 6 and delivers it to the inner cavity of the glue injection gun 5. The glue injection gun 5 injects the glue into the inner cavity of the glue injection hole 10 for glue injection connection. Before this, the second electric telescopic rod 22 drives the movable frame 23. The movement inward brings the limiting block 210 and both sides of the mold body 9 to the same horizontal line. The motor 27 drives the threaded rod 25 to rotate, causing the threaded sleeve 24 to move inward. The threaded sleeve 24 drives the support rod 28 and the limiting block 210 to move inward. The limiting block 210 moves inward and contacts both sides of the mold body 9 for limiting. At this time, the infrared sensor 35 detects the detection block 33 and transmits the detected data to the display 37 for display and the alarm 38 for analysis. When the alarm 38 detects abnormal data, it activates the alarm 38 to sound an alarm, and the display 37 emits a red light as a warning.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
