Abstract
Description
Technical Field
[0001] This invention belongs to the field of medical device injection molding panel application technology, specifically relating to a high-efficiency processing and positioning structure for medical device injection molding panels. Background Technology
[0002] Medical device injection molded panels refer to plastic panels used in medical devices manufactured through injection molding. These panels are typically made of medical-grade plastics and possess properties such as biocompatibility, chemical resistance, and high-temperature resistance, making them suitable for medical devices that come into contact with the human body.
[0003] The prior art patent publication number CN215396476U describes a high-efficiency processing and positioning structure for injection-molded panels of medical devices. This patent involves placing the mold on an adjustment table and then rotating a threaded rod to drive the external threaded sleeve downwards for adjustment. This causes the first and second rotating rods to rotate downwards from their connection point. During rotation, their lateral length changes, causing the clamping table to drive the adjustment clamping plate to move laterally. The adjustment clamping plate stops when it reaches the outer surface of the mold. This allows the adjustment clamping plate to fit tightly against the mold for stable positioning, achieving stable and reliable injection molding and thus improving processing efficiency. However, in actual use, the following shortcomings still exist: From a practical point of view, the positioning effect of this device is poor and its adaptability is low.
[0004] Therefore, there is a need for an efficient processing and positioning structure for injection-molded panels of medical devices to solve the problems existing in the prior art. Utility Model Content
[0005] The purpose of this invention is to provide a highly efficient processing and positioning structure for injection-molded panels of medical devices, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency processing and positioning structure for injection-molded panels of medical devices, comprising a base, the base being cylindrical, and having a connecting groove in the middle of the upper end of the base, a first sliding groove at the edge of the connecting groove, a placement platform fixedly connected to the base in the middle of the connecting groove, a plurality of conical limiting blocks fixedly connected to the curved surface of the placement platform, a plurality of fixing teeth on both sides of the limiting blocks, and a positioning component slidably connected between adjacent limiting blocks, and a cross guide line on the upper end of the placement platform.
[0007] It should be noted in the solution that an anti-slip pad is fixedly connected to the lower end of the base.
[0008] It is worth noting that the number of limiting blocks is twelve, and the lower center of each limiting block is fixedly connected to the bottom of the connecting groove by a connecting block.
[0009] Furthermore, it should be noted that each positioning component includes a base plate, a fixing frame is fixedly connected to the upper center of each base plate, a second sliding groove is provided in the center of each of the four sides of the fixing frame, a sliding component is slidably connected in each of the second sliding grooves, and a third sliding groove is provided on each of the four sides of the upper and lower center of the fixing frame, a top plate is fixedly connected to the upper end of the fixing frame, a fixing block is fixedly connected to the center of the upper end of the top plate, the fixing block is rectangular, a limit component is fixedly connected to the center of each of the four sides of the fixing block, a sliding hole is provided in the center of the fixing block, the sliding hole is slidably connected to the outer surface of the sliding column, a threaded head is fixedly connected to the lower end of the sliding column, and a rotating handle is fixedly connected to the upper end of the sliding column.
[0010] In a preferred embodiment, both the bottom plate and the top plate are cylindrical, and the diameter of both the bottom plate and the top plate is larger than the rectangle between adjacent limiting blocks. The fixing frame is rectangular, and the height of the fixing frame is equal to the height of the limiting block. The fixing frame can rotate freely in the gap between adjacent limiting blocks.
[0011] In a preferred embodiment, the limiting component includes a symmetrical first limiting block and a symmetrical second limiting block, and each of the symmetrical first limiting block and the symmetrical second limiting block has a plurality of right-angled grooves or a semi-circular connecting pad at its other end.
[0012] In a preferred embodiment, each sliding component includes a sliding plate. One side of the sliding plate is provided with several self-resetting teeth that can mesh with fixed teeth. A connecting plate is fixedly connected to the other side of the sliding plate. One side of the connecting plate is provided with a tapered threaded hole. The curvature of the tapered threaded hole is the same as the curvature of the thread head, and the two can be threaded together. A baffle is fixedly connected to the middle of the upper and lower ends of the sliding plate. A symmetrical return spring is fixedly connected to one side of the baffle, and the other end of the symmetrical return spring is fixedly connected to one side of the third sliding groove.
[0013] In a preferred embodiment, the sliding plate is slidably connected to the second sliding groove, and the baffle is slidably connected to the third sliding groove.
[0014] Compared with the prior art, the efficient processing and positioning structure for injection-molded panels of medical devices provided by this invention has at least the following beneficial effects:
[0015] By adjusting the positioning components according to the shape and size of the injection-molded panel, the positioning components are positioned between suitable adjacent limit blocks. Depending on the actual situation, a suitable limit component (first limit block or second limit block) is selected and pushed towards the placement platform until several positioning components position the injection-molded panel. Finally, the sliding column is rotated downwards, causing the sliding head to threadedly connect into the sliding holes of several fixed blocks. Because the sliding holes are conical and wider at the top than the bottom, the sliding head moves downwards, causing the sliding plate of the sliding component to move outwards. This allows the self-resetting locking tooth 4031 to mesh with the fixed locking tooth 301, thus fixing the positioning components. Disassembly is performed by reversing the operation. Due to the action of several symmetrical return springs, the sliding plate of the sliding component will move back. Therefore, this device can adapt to the positioning of injection-molded panels of various specifications of medical devices, improving versatility and providing multi-point uniform limiting to prevent panel displacement and enhance processing stability.

[0021] The present invention will be further described below with reference to embodiments.
[0022] Please see Figure 1-4This invention provides a high-efficiency processing and positioning structure for injection-molded panels of medical devices, comprising: a base 1, which is cylindrical and has a connecting groove 102 in the middle of its upper end; a first sliding groove 103 on the edge of the connecting groove 102; a placement platform 2 fixedly connected to the middle of the connecting groove 102; a plurality of conical limiting blocks 3 fixedly connected to the curved surface of the placement platform 2; a plurality of fixing teeth 301 on both sides of the limiting blocks 3; a positioning component 4 slidably connected between adjacent limiting blocks 3; and a cross guide line 201 on the upper end of the placement platform 2.
[0023] Further as Figure 1 As shown, it is worth noting that an anti-slip pad 101 is fixedly connected to the lower end of the base 1. The anti-slip pad 101 effectively prevents the base 1 from shifting during processing, ensures positioning accuracy, buffers equipment vibration, reduces processing noise, improves operating comfort, and avoids scratches caused by direct contact between the metal base 1 and the work surface.
[0024] Further as Figure 1 and Figure 2 As shown, it is worth noting that there are twelve limiting blocks 3, and the lower middle part of each limiting block 3 is fixedly connected to the bottom of the connecting groove 102 by a connecting block 302. The 12 conical limiting blocks 3 are evenly distributed around the circumference, so that the force deviation of the injection molded panel is less than 5%. The connecting block 302 is welded to the bottom of the connecting groove 102, which increases the torsional stiffness by 3 times. The 12 equally divided layout makes the positioning repeatability accuracy reach ±0.03mm.
[0025] Further as Figure 3 and Figure 4 As shown, it is worth noting that each positioning component 4 includes a base plate 401. A fixing frame 402 is fixedly connected to the upper center of each base plate 401. A second sliding groove 4021 is provided in the center of each of the four sides of the fixing frame 402. A sliding component 403 is slidably connected in each of the second sliding grooves 4021. A third sliding groove 4022 is provided on each of the four sides of the upper and lower center of the fixing frame 402. A top plate 407 is fixedly connected to the upper end of the fixing frame 402. A fixing block 404 is fixedly connected to the center of the upper end of the top plate 407. The fixing block 404 is rectangular, and a fixing block 404 is fixedly connected to the center of each of the four sides of the fixing block 404. A fixed connection limit component 405 is provided, and a sliding hole 4041 is provided in the middle of the fixed block 404. The sliding hole 4041 is slidably connected to the outer surface of the sliding column 406. A threaded head 4061 is fixedly connected to the lower end of the sliding column 406, and a rotating handle 4062 is fixedly connected to the upper end of the sliding column 406. XYZ three-way adjustment is achieved through the second sliding groove 4021 on the four sides of the fixed frame 402. The sliding hole 4041 and the sliding column 406 cooperate with each other, and the perpendicularity error is ≤0.05mm. The rotating handle 4062 is designed to save effort, and the operating torque is only 0.5N·m.
[0026] This solution involves the following steps: Based on the shape and size of the injection-molded panel, the positioning component 4 is positioned between suitable adjacent limiting blocks 3. Depending on the actual situation, a suitable limiting component 405 is selected, either the first limiting block 4051 or the second limiting block 4052. The positioning component 4 is then pushed towards the placement platform 2 until several positioning components 4 position the injection-molded panel. Finally, the sliding column 406 is rotated downwards, causing the threaded head 4061 to threadedly connect to the sliding hole 4041 of several fixing blocks 404. Since the sliding hole 4041 is conical and wider at the top than the bottom, the threaded head 4061 moves downwards, causing the sliding plate 4032 of the sliding component 403 to move outwards. This allows the self-resetting locking tooth 4031 to engage with the fixing locking tooth 301, thus fixing the positioning component 4. Disassembly is performed by reversing the operation. Due to the action of several symmetrical return springs 4036, the sliding plate 4032 of the sliding component 403 will move back.
[0027] According to the above working process, the anti-slip pad 101 effectively prevents the base 1 from shifting during processing, ensuring positioning accuracy, buffering equipment vibration, reducing processing noise, improving operating comfort, and preventing the metal base 1 from directly contacting the table surface and causing scratches. The 12 conical limit blocks 3 are evenly distributed around the circumference, ensuring that the force deviation of the injection molded panel is <5%. The connecting block 302 is welded to the bottom of the connecting groove 102, increasing the torsional stiffness by 3 times. The 12 equally divided layout ensures that the positioning repeatability accuracy reaches ±0.03mm. The four sides of the fixed frame 402 have a second sliding groove 4021 to achieve XYZ three-way adjustment. The sliding hole 4041 cooperates with the sliding column 406, with a verticality error ≤0.05mm. The handle 4062 is designed to save effort, requiring only 0.5N·m of operating torque.
[0028] Further as Figure 3 and Figure 4 As shown, it is worth noting that both the base plate 401 and the top plate 407 are cylindrical, and their diameters are larger than the rectangles between adjacent limit blocks 3. The fixing frame 402 is rectangular, and its height is equal to the height of the limit blocks 3. The fixing frame 402 can rotate freely in the gaps between adjacent limit blocks 3. The base plate 401 has a diameter 2mm larger than the gap between the limit blocks 3, forming a mechanical limit. The fixing frame 402 can rotate 30° in increments between the 12 limit blocks 3. The height of the top plate 407 is flush with the limit blocks 3 to avoid tool interference.
[0029] Further as Figure 3 and Figure 4As shown, it is worth noting that the limiting component 405 includes a symmetrical first limiting block 4051 and a symmetrical second limiting block 4052. The other end of the symmetrical first limiting block 4051 and the symmetrical second limiting block 4052 is provided with several right-angled grooves or semi-circular connecting pads. The right-angled grooves are adapted to the 90° panel edge, and the semi-circular connecting pads are adapted to the R3-R5 rounded corners.
[0030] Further as Figure 3 and Figure 4 As shown, it is worth noting that each sliding component 403 includes a sliding plate 4032. One side of the sliding plate 4032 is provided with several self-resetting teeth 4031, which can be engaged with the fixed teeth 301. A connecting plate 4033 is fixedly connected to the other side of the sliding plate 4032. One side of the connecting plate 4033 is provided with a tapered threaded hole 4034. The curvature of the tapered threaded hole 4034 is the same as the curvature of the thread head 4061, and the two can be threadedly connected. A baffle 4035 is fixedly connected to the middle of the upper and lower ends of the sliding plate 4032. A symmetrical return spring 4036 is fixedly connected to one side of the baffle 4035. The other end of the symmetrical return spring 4036 is fixedly connected to one side of the third sliding groove 4022. Through the sliding component 403, the position of the self-resetting teeth 4031 can be restricted, thereby restricting the position and movement of the positioning component 4.
[0031] Further as Figure 3 and Figure 4 As shown, it is worth noting that the sliding plate 4032 is slidably connected to the second sliding groove 4021, and the baffle 4035 is slidably connected to the third sliding groove 4022. The sliding plate 4032 and the second sliding groove 4021 have a fit tolerance of H7 / g6, the baffle 4035 and the third sliding groove 4022 have a gap of ≤0.01mm, the hardened track has a lifespan of 500,000 cycles, and the aluminum alloy sliding column 406 and the steel sliding hole 4041 have a CTE matching design.
[0032] In summary: By adjusting the shape and size of the injection-molded panel, the positioning component 4 is positioned between appropriate adjacent limiting blocks 3. Based on the actual situation, a suitable limiting component 405 is selected, either the first limiting block 4051 or the second limiting block 4052. The positioning component 4 is then pushed towards the placement platform 2 until several positioning components 4 position the injection-molded panel. Finally, the sliding column 406 is rotated downwards, causing the threaded head 4061 to be threaded into the sliding hole 4041 of several fixing blocks 404. Since the sliding hole 4041 is conical and wider at the top than at the bottom, the threaded head 4061 moves downwards, causing the sliding plate 4032 of the sliding component 403 to move outwards. This allows the self-resetting locking tooth 4031 to mesh with the fixed locking tooth 301, thus fixing the positioning component 4. During disassembly, the operation is reversed. Due to the action of several symmetrical return springs 4036, the sliding plate 4032 of the sliding component 403 will move back. The diameter of the base plate 401 is 2mm larger than the gap of the limit block 3, forming a mechanical limit. The fixing frame 402 achieves 30° indexing rotation among the 12 limit blocks 3. The height of the top plate 407 is flush with the limit block 3 to avoid tool interference. The right-angle groove is adapted to the 90° panel edge, and the semi-circular connecting pad is adapted to the R3-R5 rounded corner. The sliding component 403 can limit the position of the self-resetting tooth 4031, thereby limiting the position and movement of the positioning component 4. The sliding plate 4032 and the second sliding groove 4021 have a fit tolerance of H7 / g6. The gap between the baffle 4035 and the third sliding groove 4022 is ≤0.01mm. The hardened track has a life of 500,000 cycles. The aluminum alloy sliding column 406 and the steel sliding hole 4041 have a CTE matching design.
